24 May 2002 - ISS Status Report: ISS 02-25. The Expedition 4 crew of the International Space Station spent much of this week preparing for the arrival of Endeavour on STS-111 and their return home. They packed equipment and supplies for return to Earth aboard Endeavour. They also reconfigured and checked out spacesuits and the station's joint airlock in preparation for three spacewalks at the station by Endeavour mission specialists Franklin Chang-Diaz and Philippe Perrin.

Expedition 4 Commander Yury Onufrienko and astronauts Carl Walz and Dan Bursch were launched last Dec. 5 aboard Endeavour's STS-108 mission, and have been on the ISS since Dec. 7.

Endeavour is scheduled for launch on May 30. That would result in a docking with the station on June 1. Endeavour Commander Ken Cockrell, Pilot Paul Lockhart, and mission specialists Chang-Diaz and Perrin are bringing the Expedition 5 crew to the station. That crew is commanded by Valery Korzun and includes astronaut Peggy Whitson and cosmonaut Sergei Treschev.

The first two of the three spacewalks by Chang-Diaz and Perrin will focus on installation of a new Mobile Base System for the station's robotic arm, Canadarm2. It will allow the arm to move along the railroad-like tracks of station's main truss, eventually to reach a length of more than 350 feet. The third spacewalk is to change out the wrist roll joint of Canadarm2.

On Friday, Dan Bursch worked with the Biomass Production System, a plant growth experiment using wheat and a plant related to cabbage and radishes. Each crewmember was scheduled for an hour to pack personal possessions, as they have been for much of this week. On Thursday Walz and Bursch completed their final session with the PuFF (pulmonary function in flight) experiment, which looks at effects of microgravity on lung function.

Several experiments have been deactivated, including the Physics of Colloids in Space, which was shut down Tuesday and which will be returned to Earth on Endeavour. It is a study of fine particles suspended in a fluid. An example of such fluids is paint.

Major systems aboard the station continue to function well as the ISS orbits at an average altitude of about 243 statute miles.

• Bay 1-2: Orbiter Docking System - 1800 kg + 2 EMU spacesuits - 240 kg
• Bay 4: Mobile Base System (MBS) - 1600 kg. The Mobile Base System was made by MD Robotics of Brampton, Ontario. It was to be attached to the Mobile Transporter and used to mount the SSRMS Canadarm-2 arm and heavy payloads.
• Bay 6P: Adapter Beam / Wrist Roll Joint - 150 kg. The WRJ (Wrist Roll Joint) would be swapped with the broken one on the SSRMS arm.
• Bay 7-12: MPLM FM1 "Leonardo" - 10557 kg. The Leonardo module carried 8 Resupply Stowage Racks and 4 Resupply Stowage Plaftorms, with equipment to be transferred to the station. It also carried two science racks: the MSG (Microgravity Science Glovebox) and Express-3, which would be installed on Destiny. Leonardo, built by Alenia Spazio in Torino, also flew on STS-102 and STS-105.
• Bay 13P: ICAPC Beam / PGDF - 75 kg. The PGDF (Power-Data Grapple Fixture) would be installed on the P6 truss.
• Bay 13S: Adapter Beam / SMDP - 200 kg. The Service Module Debris Panels (SMDP) package contained 6 panels which would be stowed on PMA-1 until a later spacewalk attached them to the Zvezda module to protect it from space debris hits.
• Total: 14622 kg

Aboard Endeavour are Commander Ken Cockrell, Pilot Paul Lockhart, Mission Specialists Franklin Chang-Díaz and Philippe Perrin of the French Space Agency, CNES, along with Expedition 5 Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev. As Endeavour launched from Florida, the space station orbited 240 statute miles over the southern Indian Ocean west of Perth, Australia.

Aboard the ISS, Expedition 4 Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch are wrapping up their 182nd day in space, their 180th day on the station. Walz and Bursch will break the U.S. record for the longest single space flight - 188 days - set by astronaut Shannon Lucid in 1996. Another record was equaled today as Chang-Díaz became only the second human to fly in space seven times, tying a mark set in April by Jerry Ross on the STS-110 mission.

Less than nine minutes after launch, Endeavour and its crewmembers settled into orbit and work began to prepare the shuttle for its planned 12-day mission.

Endeavour is scheduled to dock to the station Friday afternoon, setting the stage for the handover between the Expedition 4 and Expedition 5 station crews. Three spacewalks are scheduled during the mission by Chang-Díaz and Perrin. The first two will help install and activate the Mobile Base System, a platform that will be mated to the Mobile Transporter on the S-Zero (S0) Truss. The new platform will allow the station's Canadarm2 robotic arm to "walk off" the Destiny Laboratory onto the Mobile Base System so it can be transported up and down the length of the ISS for future assembly tasks. On the third spacewalk, Chang-Díaz and Perrin will replace a faulty wrist roll joint on the station's robotic arm that has experienced an electrical problem in one of its two data and power channels.

The shuttle crew will go to sleep at 10:23 p.m., and will be awakened at 6:23 a.m. Thursday to begin its first full day in orbit.

Aboard Endeavour, Commander Ken Cockrell, Pilot Paul Lockhart, Mission Specialists Philippe Perrin and Franklin Chang-Díaz and Expedition Five Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev, were awakened at 6:23 a.m. Central time by the song "Gettin' Jiggy Wit It," by Will Smith. The song was played for Korzun, who will soon take command of the space station.

The Expedition Four crewmembers - Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch - are in their 183rd day in space, their 181st day aboard the ISS. They will return to Earth aboard Endeavour after six months in orbit on June 17.

In preparation for docking Friday, Perrin and Chang-Díaz will set up a centerline camera to help Cockrell with views of the station's docking mechanism during Endeavour's final approach tomorrow and will test the orbiter docking system ring. Cockrell and Lockhart will fire the shuttle's jets to raise the altitude of Endeavour and draw it closer to the station. The maneuvers will bring the shuttle about 46 statute miles behind the station by Friday morning.

Cockrell and Perrin will also activate the shuttle's robotic arm and use its cameras to survey the contents of the payload bay, including the Leonardo Multi-Purpose Logistics cargo module, the Mobile Base System and the replacement wrist roll joint for the station's robotic arm, Canadarm2, as well as debris shields for the Zvezda Service Module. Chang-Díaz and Perrin will install these components during three spacewalks scheduled for the mission. Today, they will prepare their spacesuits for use out of the Quest Airlock on the station next week.

Later this morning, Cockrell and Chang-Díaz will participate in a live conversation with Costa Rican President Abel Pacheco and reporters from two Hispanic television networks. Costa Rican-born Chang-Díaz tied the human spaceflight record yesterday when he launched on his seventh mission. Astronaut Jerry Ross set the record in April during the STS-110 mission.

Commander Ken Cockrell, Pilot Paul Lockhart and Mission Specialists Philippe Perrin and Franklin Chang-Díaz, and Expedition Five Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev, were awakened just after 4:30 Central time this morning by "American Woman," by Lenny Kravitz, a song selected for Whitson.

At the time of the crew's wakeup call, Endeavour had closed to within 900 statute miles of the ISS, aiming for a linkup to the docking port at the forward end of the Destiny Laboratory at 11:17 a.m. Central time as the two vehicles fly off the northeast coast of Australia, south of New Guinea. On board the station, the Expedition Four crew, Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch, are spending the morning preparing for the arrival of Endeavour's astronauts and their Expedition Five replacements. Onufrienko, Walz and Bursch are in their 184th day in space, their 182nd day aboard the ISS.

A little less than two hours after Endeavour docks to the station, the hatches between the two spacecraft will open and Onufrienko, Bursch and Walz will greet their counterparts and conduct a safety briefing. Then, the ten astronauts and cosmonauts will begin transferring equipment, supplies and experiments between the two vehicles. The two Expedition crews will exchange their custom-made Soyuz return craft seat liners for the rescue vehicle currently docked to the station. Once the new Expedition Five crew conducts checks of their Russian entry suits, they will officially take over command of station operations, and Onufrienko, Walz and Bursch will become shuttle crewmembers.

All systems aboard Endeavour and the ISS continue to function in excellent shape.

At 2:08 p.m. central time, hatches between Endeavour and the station swung open, and the station's Expedition Four crewmembers-Commander Yury Onufrienko and Flight Engineers Dan Bursch and Carl Walz-greeted their visitors-Cockrell, Lockhart, Mission Specialists Franklin Chang-Díaz and Philippe Perrin and oncoming Expedition Five Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev.

The 10 astronauts and cosmonauts immediately set to work transferring priority equipment, supplies and experiments between the two vehicles. Items moving to the station included two Extravehicular Activity spacesuits and EVA tools to be used during the mission's three scheduled spacewalks. The Expedition Five crewmembers' custom-made Soyuz return craft seat liners and their Russian entry suits were transferred from Endeavour to the station at 5:55 p.m. central time, marking the official start of the Expedition Five Increment. With that transfer complete, Onufrienko, Bursch and Walz formally concluded their 182-day stay as space station residents. Korzun, Whitson and Treschev now begin their tenure as the fifth resident crew to live and work on board the International Space Station.

Communications checks between the station's Quest Airlock and the EVA suits Perrin and Chang-Díaz will use also were completed today. The spacewalks will see installation of a new platform, the Mobile Remote Servicer Base System, on the station's railcar, the Mobile Transporter, and replacement of the wrist roll joint on the station's arm.

Late in the day, the Flash Evaporator System Primary B controller failed for an as-yet unknown reason. The system has three redundant controllers, Primary A, Primary B and Secondary, and the failure of one controller will have no effect on mission operations.

The Flash Evaporator System sprays excess supply water into the inside of a trash-can shaped vessel that is wrapped by Freon coils. The heat being carried in these coils causes the water to flash into vapor and be vented overboard, disposing of excess heat and excess supply water.

The newly arrived crewmembers of Expedition Five aboard the International Space Station - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - will continue settling into their new home today as they work with Endeavour's astronauts to move the Leonardo Multi-Purpose Logistics Module from the shuttle's cargo bay to the Unity module of the complex in advance of the start of the transfer of almost 3 tons of equipment and supplies.

Commander Ken Cockrell, Pilot Paul Lockhart and Mission Specialists Philippe Perrin and Franklin Chang-Díaz, and the newest shuttle crewmembers - former Expedition Four Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch, were awakened at 4:23 Central time this morning by "I Have a Dream," by ABBA, a song selected for Treschev.

Using the shuttle's robotic arm, Cockrell and Perrin will reach into Endeavour's payload bay and latch onto Leonardo at mid-morning. The pressurized cargo module will be attached to the nadir berthing port on Unity. After Walz and Whitson perform pressure checks, the hatch to the cargo carrier will be opened. Leonardo contains equipment, supplies and experiments necessary for the fifth resident crew's 4 ½-month stay in orbit.

The six Expedition crewmembers will continue their handover conferences and the 10 cosmonauts and astronauts will review procedures for the first spacewalk of the flight tomorrow. Perrin and Chang-Díaz will step out of the Quest Airlock Sunday to begin installing the Mobile Base System, a new platform which will enable the station's robotic arm, Canadarm2, to ride a railway the length of the station for future assembly tasks. Two more spacewalks are scheduled for Tuesday and Thursday to complete the Mobile Base system installation and to replace an ailing wrist roll joint on the station's robotic arm.

The Expedition Five crew officially assumed command of station operations yesterday at 5:55 p.m. Central time, marking the end of the Expedition Four increment at 181 days. Onufrienko, Walz and Bursch are now considered part of Endeavour's crew, aiming for a homecoming on June 17.

Systems on Endeavour and the ISS are functioning normally as the two vehicles orbit the Earth every 90 minutes at an altitude of 240 statute miles.

The Leonardo Multi-Purpose Logistics Module (MPLM) was unberthed from the payload bay early this morning by Commander Ken Cockrell operating the shuttle's robotic arm to move the module to the station's Unity module. Leonardo's installation proceeded perfectly with completion at 9:28 a.m. Central time. About 4:30 p.m. Central time, the MPLM's hatch was opened. Dan Bursch of Expedition Four called down at 4:52 pm that all crew members had entered the logistics module and were working to get the transfers rolling. The crew got a good start on the movement of more than 5,600 pounds of cargo to the station.

Early today, one of four control moment gyroscopes used in the station's attitude control system experienced a mechanical failure. Flight controllers turned it off and began using the remaining three gyros to maintain the station's attitude. It is believed that one of its spin bearings failed, causing it to seize. Flight Engineer Carl Walz reported that the crew could feel and hear "growling" vibrations as it failed. While the failure is a serious complication for the long-term space station operations, there are multiple backup systems for control of the station's attitude so it poses no threat to the safety of the shuttle or expedition crews. The situation is expected to require only minor changes to the STS-111 flight activities.

Franklin Chang-Díaz, and Perrin, with help from Paul Lockhart, readied their extravehicular mobility unit space suits and tools, and reviewed procedures for Sunday's spacewalk. The two first-time spacewalkers will install a Power and Data Grapple Fixture (PDGF) to the station's P6 solar array truss and temporarily store some Russian meteoroid/debris shields. They'll also remove thermal blankets from the Mobile Base System (MBS) in Endeavour's cargo bay, and support its unberthing. The MBS will be parked on the shuttle's arm near its installation point so that hardware temperatures can equalize before it is attached to the existing Mobile Transporter platform. At the end of the day, flight controllers will activate the MBS from the ground in preparation for the next day's operations. Chang-Díaz also will inspect and photograph the exterior condition of station's failed control moment gryoscope at the end of his spacewalk.

The combined STS-111 crew of Cockrell, Lockhart, Chang-Díaz, Perrin, Yury Onufrienko, Dan Bursch and Carl Walz will wake up at 4:23 am CDT Sunday, while new station Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev will arise at 4:53 am.

Commander Ken Cockrell, Pilot Paul Lockhart and Mission Specialists Philippe Perrin and Franklin Chang-Díaz, and the newest shuttle crewmembers - former Expedition Four Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch, were awakened at 4:23 Central time this morning by "I Have a Dream," by ABBA, a song selected for Treschev.

Using the shuttle's robotic arm, Cockrell and Perrin will reach into Endeavour's payload bay and latch onto Leonardo at mid-morning. The pressurized cargo module will be attached to the nadir berthing port on Unity. After Walz and Whitson perform pressure checks, the hatch to the cargo carrier will be opened. Leonardo contains equipment, supplies and experiments necessary for the fifth resident crew's 4 ½-month stay in orbit.

The six Expedition crewmembers will continue their handover conferences and the 10 cosmonauts and astronauts will review procedures for the first spacewalk of the flight tomorrow. Perrin and Chang-Díaz will step out of the Quest Airlock Sunday to begin installing the Mobile Base System, a new platform which will enable the station's robotic arm, Canadarm2, to ride a railway the length of the station for future assembly tasks. Two more spacewalks are scheduled for Tuesday and Thursday to complete the Mobile Base system installation and to replace an ailing wrist roll joint on the station's robotic arm.

The Expedition Five crew officially assumed command of station operations last night just before 6 p.m. Central time, marking the end of the Expedition Four increment at 182 days. Onufrienko, Walz and Bursch are now considered part of Endeavour's crew, aiming for a homecoming on June 17.

Systems on Endeavour and the ISS are functioning normally as the two vehicles orbit the Earth every 90 minutes at an altitude of 240 statute miles.

With the help of Endeavour Pilot Paul Lockhart, who will help coordinate the spacewalk from inside Endeavour, Chang-Díaz and Perrin will leave the Quest Airlock this morning for a planned six-hour spacewalk to first install a Power and Data Grapple Fixture to the station's P6 truss for its future relocation. The two first-time space walkers will then temporarily park micrometeoroid debris shields on the Russian segment of the station. Expedition Five Flight Engineer Peggy Whitson and ISS Commander Valery Korzun will install the shields on the Zvezda Service Module during a spacewalk set for late July.

The final task of the spacewalk will involve the removal of thermal blankets from the Mobile Base System. That component will be mated tomorrow to the Mobile Transporter on the S0 (S-Zero) Truss of the ISS to enable the Canadarm2 robotic arm to "walk off" the Destiny Laboratory onto the station's railcar system for transport up and down the length of the complex. Chang-Díaz will be identifiable by solid red stripes on the legs of his spacesuit. Perrin will wear the pure white suit with no stripes.

Commander Ken Cockrell will use the shuttle robotic arm's cameras to monitor the activities outside. Whitson and Endeavour Astronaut Carl Walz will transport Chang-Díaz on the end of Canadarm2 during the spacewalk.

During the spacewalk, Chang-Díaz will conduct a visual and photographic inspection of one of the station's four control moment gyroscopes (CMGs) on the station's Z1 Truss. The gyroscope experienced a mechanical failure of its spin bearing yesterday and will no longer be able to be used to assist in station attitude control.

Three other CMGs are operating normally to provide full attitude control for the ISS. If necessary, station control can be maintained with only two functioning CMGs, with other backup attitude control systems also available. The CMG failure will have no impact on ISS operations. A substitute CMG is available on the ground and program managers are evaluating future replacement options. To accommodate the use of three CMGs and varying thermal conditions, the orientation of the shuttle and station will be altered slightly for today's spacewalk.

Once the protective blankets are removed from the Mobile Base System, Whitson and Walz will latch onto the platform in Endeavour's cargo bay with Canadarm2, remove it from its carrier, and maneuver it to a position just above the Mobile Transporter, which was installed on the S-Zero Truss in April. Canadarm2 will be left in a parked position overnight to thermally condition the Mobile Base System before it is mated to the Transporter railcar Monday.

At the start of their fifth day in space, Endeavour's crew was awakened at 4:23 a.m. Central time to the sound of "Drops of Jupiter" by Train, a tune selected for Cockrell.

Chang-Díaz and Perrin ventured outside the station's Quest airlock at 10:27 a.m. Central time. With the help of Endeavour Pilot Paul Lockhart, who guided the spacewalk from inside the shuttle, Chang-Díaz and Perrin first installed a Power and Data Grapple Fixture to the station's P6 truss. The fixture will be used to relocate the P6 truss structure to its final location on the station.

Attached to a foot restraint at the end of the station's robotic arm, Canadarm2, operated by Expedition Five Flight Engineer Peggy Whitson and ISS Commander Valery Korzun, Chang-Díaz gathered six micrometeoroid debris shields from the shuttle cargo bay and, with help from Perrin, temporarily stored them on Pressurized Mating Adapter-1 which links Unity to Zarya. Whitson and Korzun will install the shields on the Zvezda Service Module during a spacewalk set for late July.

Chang-Díaz then conducted a visual and photographic inspection of one of the station's four control moment gyroscopes on the station's Z1 truss, a task that was added to today's spacewalk after the gyroscope experienced a mechanical failure yesterday. The photos may help ground controllers better understand why the gyroscope failed.

Removal of thermal blankets from the Mobile Remote Servicer Base System or MBS was the final task of the spacewalk. At 5:21 p.m. Endeavour Commander Ken Cockrell commanded the release of latches that had secured the MBS to its carrier in the payload bay. Whitson and Carl Walz then latched onto the MBS with Canadarm2, removed it from its carrier, and maneuvered it to a position about three feet above the station's railcar, the Mobile Transporter. Canadarm2 will be left in a parked position overnight to thermally condition the MBS before it is mated to the railcar Monday.

Later, the Canadarm2 robotic arm will be commanded to "walk off" its position attached to the Destiny Laboratory onto a Power and Data Grapple Fixture atop the MBS. The arm will then be able to move up and down along the station truss for use in future assembly operations.

Following an inventory of the tools they used during the spacewalk, Perrin and Chang-Díaz re-entered Quest. Airlock repressurization began at 5:41 p.m. Central time, signaling the end of the spacewalk.

The MBS was attached to the Mobile Transporter on the Destiny Lab at 8:03 a.m. Central by Expedition Five Flight Engineer Peggy Whitson and Endeavour Astronaut Carl Walz. The two used the station's robotic arm, Canadarm2, to maneuver the MBS into position. Controllers on the ground then commanded latches on the transporter to close, securing the MBS in place. Eventually, Canadarm2 will "walk off" its current base location on the Destiny Lab onto the MBS. The MBS is an important part of the station's future Mobile Servicing System, which will allow the station's arm to travel the length of the station to perform future construction tasks.

The astronauts and cosmonauts on the Shuttle/Station complex, including STS-111 Commander Ken Cockrell, Pilot Paul Lockhart, Mission Specialists Philippe Perrin and Franklin Chang-Díaz, as well Expedition Four crew Yury Onufrienko, Dan Bursch and Walz, and Expedition Five crewmembers Whitson, Commander Valery Korzun and Flight Engineer Sergei Treschev, continued their transfer of equipment and supplies to the station from the Leonardo Multi-Purpose Logistics Module. As they began their Monday morning in space, the crewmembers already had transferred 73 percent of the equipment and supplies.

Though the Expedition Five crew has been in charge of station operations since Friday afternoon, an official change of command ceremony between the two Expedition crews took place this afternoon. The crew also reviewed procedures for tomorrow's second spacewalk of the mission by Chang-Díaz and Perrin in which the two astronauts will hook up cables between the Mobile Base System and the Mobile Transporter and firmly bolt the two components together.

At 4:53 p.m. today, Endeavour completed a one-hour reboost maneuver to increase the station's altitude by a little over a mile. This is the first of three such maneuvers that eventually will raise the station's altitude by six miles. Systems on both Endeavour and the station continue to function normally as they orbit the Earth every 90 minutes at an altitude of about 240 statute miles.

The Mobile Base System (MBS), parked overnight on the station's robotic arm about three feet from installation, has had a chance to receive the proper thermal conditioning to match the temperatures on the Mobile Transporter, the actual railcar on the truss itself. Operated by Expedition Five Flight Engineer Peggy Whitson and Endeavour Astronaut Carl Walz, the space station robotic arm will mate the MBS platform to the railcar and flight controllers on the ground will command latches to close to secure the platform in place. Eventually, the station arm will "walk off" its current base location on the Destiny Laboratory to the MBS and ride the railway to move up and down the entire length of the station.

The 10 astronauts and cosmonauts on the Shuttle/Station complex will also continue their transfer of equipment and supplies to the station from the Leonardo Multi-Purpose Logistics Module.

Endeavour's crew - Commander Ken Cockrell, Pilot Paul Lockhart, Mission Specialists Philippe Perrin and Franklin Chang-Díaz, and former station residents Yury Onufrienko, Walz and Dan Bursch - were awakened at 4:23 a.m. Central time to "I Only Have Eyes for You" by the Flamingoes, from the American Graffiti soundtrack which was selected for Lockhart.

Although Expedition Five crewmembers Whitson, Commander Valery Korzun and Flight Engineer Sergei Treschev have been in charge of ISS operations since Friday afternoon, an official change of command ceremony between Expedition crews will occur early this afternoon.

The crews will also participate late today in a review of procedures for tomorrow's second spacewalk by Chang-Díaz and Perrin to hook up cables between the Mobile Base System and the Mobile Transporter and to bolt the two components together. Systems on both Endeavour and the ISS continue to function normally as the two craft orbit the Earth every 90 minutes at an altitude of about 240 statute miles.

Working side by side, the Endeavour crew - Ken Cockrell, Paul Lockhart, Franklin Chang-Díaz, Philippe Perrin, Yury Onufrienko, Carl Walz and Dan Bursch - and the Expedition Five crew of Valery Korzun, Peggy Whitson and Sergei Treschev have transferred approximately 4,500 of the expected 4,665 pounds of material that will return to Earth inside the MPLM. All of the items slated to be moved from Endeavour's middeck to the station have been transferred and the astronauts are now restowing return items.

Also today, Endeavour's small steering jets were fired in a series of pulses to gently raise the station's orbit by another mile. This was the second of three scheduled reboost maneuvers designed to raise the station's altitude by a total of six miles.

The crewmembers also reviewed the plans for the third and final scheduled spacewalk of the mission. Thursday morning, at 9:43 a.m. Central, Chang-Díaz and Perrin will float out of the Quest airlock and begin work to replace a faulty wrist-roll joint on the space station's robotic arm, Canadarm2. The spacewalk is slated to last about seven hours.

This afternoon, the crews took a break from the stowage activities to discuss the progress of their mission with reporters in the U.S., France and Canada during a joint crew news conference.

Endeavour's payload bay cameras captured views of wildfires burning in Colorado about 4:40 p.m Central today. Smoke rising from the wildfires was clearly visible as the shuttle/station complex orbited 240 miles over the surface of the Earth.

The two crews are scheduled to go to sleep just before 8 p.m. today and will awaken just before 4 a.m. Thursday. All systems on both Endeavour and the International Space Station continue to function normally as the two craft orbit the Earth every 90 minutes at an altitude of 240 statute miles.

At 1:55 a.m. Central time, Walz set a new U.S. record for most aggregate days spent in orbit, exceeding Shannon Lucid's record as he reached the 223 day mark accrued over five flights. Last night, Walz and Bursch also surpassed Lucid's U.S. single spaceflight endurance record of 188 days at 9:19 p.m. Central time.

Today, along with Expedition Five Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev, the 10 astronauts and cosmonauts will continue to transfer unneeded station equipment and supplies to the Leonardo Multi-Purpose Logistics Module to be returned to earth. Handover conferences will also continue between the two Expedition crews.

The crewmembers will also review the plans for the third and final spacewalk of the mission on Thursday. Chang-Díaz and Perrin will replace a faulty wrist roll joint on the space station's robotic arm, the Canadarm2.

Reporters in the U.S., France and Canada will also have a chance to question the two crews on the progress of the flight during a Joint Crew News Conference this afternoon.

The second of three reboosts of the station's altitude will be performed later today, using the shuttle jets to counter the natural effects of atmospheric drag on the station's orbit.

All systems on both Endeavour and the International Space Station continue to function normally as the two craft orbit the Earth every 90 minutes at an altitude of 240 statute miles.

Canadarm2 experienced an electrical problem in March in one of two redundant power and data channels which command the operation of the seven-jointed apparatus. It was determined that a short created inadvertent commanding in the arm's primary channel which resulted in the unexpected activation of the arm's brakes. The backup commanding channel has functioned perfectly. Even though the arm has continued to operate flawlessly through a software modification, the replacement of the problematic wrist joint was added to the STS-111 mission.

Inside the shuttle, Pilot Paul Lockhart will choreograph the planned seven-hour spacewalk while Commander Ken Cockrell will use the shuttle's robotic arm to provide television views of the spacewalk activity. Inside the station, Endeavour Astronaut Dan Bursch and Expedition Five Commander Valery Korzun will conduct a checkout of the health of the arm once the new joint is installed. Expedition Five Flight Engineers Peggy Whitson and Sergei Treschev will continue cargo transfer activities throughout the day.

Each joint of Canadarm2 is attached to the next joint by six bolts and an additional bolt that disconnects power, data and video connections. The first task for the spacewalkers is to remove the latching end effector (LEE), essentially the hand of Canadarm2, leaving the faulty wrist roll joint exposed. Next they will disconnect the wrist roll joint and Perrin will carry the failed unit to Endeavour's payload bay to temporarily store it next to the new joint. Chang-Díaz will assist in removing the new joint from its launch carrier and Perrin will bring it up to Canadarm2. The spacewalkers will align the new component with the wrist yaw joint at the end of the arm, tighten the six bolts and turn the final bolt to connect power, data and video lines. They will reinstall the LEE and power will be turned back onto Canadarm2.

Endeavour's astronauts - Cockrell, Lockhart, Chang-Díaz, Perrin, Bursch, Yury Onufrienko and Carl Walz - were awakened just before 4 a.m. Central time this morning to the song, "On the Road Again," by Willie Nelson, selected for Walz by his family. Walz is returning to Earth after a six-month stay in orbit.

All systems on both Endeavour and the International Space Station continue to function normally as the two craft orbit the Earth every 90 minutes at an altitude of 240 statute miles.

Working with the International Space Station's Expedition Five crew, Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev, Endeavour's astronauts will deactivate the Leonardo Multi-Purpose Logistics Module and will remove it from its location on the Unity node of the International Space Station. Using the shuttle's robotic arm, Cockrell will place the module back into Endeavour's cargo bay for its return to Earth.

About 5,600 pounds of equipment and supplies are being left behind on the ISS, including a new phone booth-sized rack to house delicate microgravity experiments and a glovebox to provide the Expedition Five crew future hands-on interaction with contained experiments. The cargo module is returning with 4,665 pounds of discarded equipment and supplies to Earth.

Last night, an initial attempt to provide power from the newly installed Mobile Base System platform to the space station robotic arm, Canadarm2, was not successful. Engineers believe that a minor software glitch is preventing commanding from the platform to reach the newly refurbished robotic arm so that the new platform, rather than the Destiny Laboratory, can provide power for the arm. This is not believed to be a serious problem, and should be corrected well before the arm "walks off" its base location on the Destiny to use the Mobile Base System as its formal platform for a ride down the length of the station's truss structure. Canadarm2 received a new wrist roll joint yesterday during the final spacewalk of the flight by Chang-Díaz and Perrin, and the arm itself has full functionality and redundancy.

Endeavour's steering jets are being used to raise the station's altitude a third and final time today prior to tomorrow's scheduled undocking. The three maneuvers are expected to raise the altitude of the ISS by around six statute miles.

Endeavour is scheduled to undock from the ISS Saturday morning at 9:32 a.m. Central time while the two spacecraft fly over western Kazakhstan, not far from Russia's primary launch site at the Baikonur Cosmodrome. Once Endeavour departs, ISS residents Korzun, Whitson and Treschev will begin their 4 ½ month mission in earnest, unpacking gear and settling in to their new home in orbit.

All systems on both Endeavour and the International Space Station continue to function normally as the two craft orbit the Earth every 90 minutes at an altitude of 240 statute miles. Endeavour is scheduled to undock from the space station Saturday morning.

Endeavour astronaut Philippe Perrin completed the last major task of the STS-111 mission today when he successfully returned the Leonardo Multi-Purpose Logistics Module to the shuttle's payload bay at 3:11 p.m. Central.

Leonardo brought a total of 8,062 pounds of supplies and equipment to the space station, including a new science rack to house microgravity experiments and a glovebox that will allow station crews to conduct experiments that require isolation. More than 1,000 pounds of equipment was also brought to the station on Endeavour's middeck.

In addition to carrying home the results of several science experiments, Leonardo is returning to Earth with 4,667 pounds of equipment and supplies that are no longer needed aboard the station. More than 1,000 pounds of equipment also will be returned to Earth in Endeavour's middeck.

Endeavour's steering jets were used today to raise the station's altitude by an additional four miles, the third and final reboost of the mission. Together, the three reboosts raised the altitude of the station by approximately six miles.

Early Saturday morning, about 6:30 central time, following final goodbyes, the hatches between the two spacecraft will swing shut. About three hours later, the crew of Endeavour - Ken Cockrell, Paul Lockhart, Franklin Chang-Díaz, Perrin, Dan Bursch, Yury Onufrienko and Carl Walz - will depart the space station, leaving the Expedition Five crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - to begin their 4½ -month mission of continued station growth and scientific research.

All systems on both Endeavour and the International Space Station continue to function normally as the two craft orbit the Earth every 90 minutes at an altitude of 240 statute miles.

After final farewells and the closing of the hatches between the two vehicles, Endeavour will undock from the ISS at 9:32 a.m. Central time as the two craft fly over western Kazakhstan, not far from Russia's primary launch site at the Baikonur Cosmodrome.

The initial separation will be provided by springs that will gently push the shuttle away from the station. When Endeavour is about two feet away from the station and the docking devices are clear of one another, Pilot Paul Lockhart will fire Endeavour's steering jets to begin slowly moving away.

About 45 minutes after undocking, when Endeavour is 450 feet in front of the ISS, Lockhart will begin a one-hour flyaround of the station. After 1 1/4 laps of the complex, Lockhart will fire Endeavour's jets to move away from the station about 11:16 a.m. Once Endeavour departs the outpost for the final time, the new ISS crew will begin to unpack gear and prepare for its long duration stay on orbit.

Endeavour's astronauts - Lockhart, Chang-Diaz, Commander Ken Cockrell, Philippe Perrin, Dan Bursch, Yury Onufrienko and Carl Walz - were awakened just before 3:30 Central time this morning to the song, "Hello to All the Children of the World", prepared for Bursch by his son's classmates.

Endeavour is scheduled to land at the Kennedy Space Center just before noon Central time Monday, bringing Onufrienko, Bursch and Walz home after 194 days in space, which for Walz and Bursch will set a new U.S. single spaceflight endurance mark. Landing Monday will result in one more day in space for Onufrienko than he logged in 1996 as Commander of the former Russian Mir Space Station.

Endeavour and the ISS to continue to function normally as they orbit at an altitude of around 240 statute miles.

After final farewells among the STS-111 and Expedition Four and Five crews, the hatches between the spacecraft were closed at 7:23 a.m. Central today. Following a series of pressure and leak checks, Endeavour gently undocked from the Station at 9:32 a.m. as the two spacecraft flew over western Kazakhstan.

As Endeavour departed the station, Whitson rang the ship's bell on board, announcing "Expedition Four departing, Endeavour departing." Dan Bursch, who along with Yury Onufrienko and Carl Walz, spent 181 days aboard the station, responded with "smooth sailing, Peggy." After a 1 ¼ lap flyaround of the station, Pilot Paul Lockhart fired a final separation burn of Endeavour's engines at 11:15 a.m. and began its final departure from the station. The two spacecraft are now about 315 miles apart, with the gap widening by 40 miles every orbit.

Both crews will enjoy some well-deserved time off today to relax following a busy week of joint operations. Endeavour's crew will go to sleep at 7:23 p.m. today, waking at 3:23 a.m. Sunday. The Expedition Five crew began an extended sleep period about 3 p.m., shifting over to its standard daily wakeup time of 1 a.m. on Sunday.

The focus of activities aboard Endeavour on Sunday will include a checkout of the systems that will be used during Monday's planned landing at the Kennedy Space Center. Endeavour is scheduled to land at the Kennedy Space Center just before noon Central time Monday, bringing Onufrienko, Bursch and Walz home after 194 days in space.

Aboard the station, Korzun, Whitson and Treschev will begin unpacking some of the supplies and equipment transferred from Endeavour and set up house for their planned 4 ½ month stay on the station. They are scheduled for about four hours of off-duty time Sunday.

Today, Commander Ken Cockrell, Pilot Paul Lockhart and Flight Engineer Franklin Chang-Diaz activated one of three hydraulic power units on Endeavour, tested all of its aerosurfaces, and then test-fired Endeavour's steering jets. The remaining crew members - Philippe Perrin of CNES, and former Expedition Four crewmembers Yury Onufrienko, Carl Walz and Dan Bursch - continued packing up gear and hardware in anticipation of tomorrow's landing.

Endeavour has two opportunities to land at the Kennedy Space Center on Monday. The first begins with a deorbit burn of the Orbital Maneuvering System engines at 10:51 a.m., followed by a landing at 11:59 a.m. Central time (12:59 p.m. Eastern.) In the event weather prevents a landing on that first opportunity, there is a second opportunity, beginning with a deorbit burn at 12:30 p.m. and resulting in a 1:36 p.m. Central (2:36 p.m. Eastern) landing in Florida. Preliminary weather forecasts call for the possibility of clouds and rain showers within the vicinity of the three-mile long landing strip on Monday. The backup landing site at California's Edwards Air Force Base was not called up for support Monday. Endeavour has sufficient consumables to remain in orbit, if necessary, until Thursday.

Onufrienko, Bursch and Walz took a few minutes this afternoon to talk with Fox News, WOIO-TV of Cleveland - Walz' hometown, and WICZ-TV of Vestal, NY - Bursch's hometown. The crew extended their best wishes on this Father's Day and discussed their 193-day stay in space. With an on-time landing Monday, Onufrienko, Bursch and Walz will have spent 194 days in space.

Meanwhile, aboard the space station, the Expedition Five crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - spent today settling into their new home, unpacking some of the equipment and hardware carried to the station by Endeavour. They also enjoyed a few hours of off-duty time today.

Endeavour's crew will begin a scheduled eight-hour sleep period at 7:23 p.m. today, waking just before 3:30 a.m. Monday to prepare for a homecoming to the Kennedy Space Center.

Commander Ken Cockrell, Pilot Paul Lockhart, Mission Specialists Franklin Chang-Diaz and Philippe Perrin, and returning Expedition 4 crewmembers Yury Onufrienko, Carl Walz and Dan Bursch were awakened at 3:23 a.m. to "Where My Heart Will Take Me," the theme song from Star Trek: Enterprise, performed by Russell Watson.

Today, Cockrell, Lockhart and Chang-Diaz will test the reaction control system jets and flight control surfaces that will be used to guide Endeavour through the atmosphere Monday morning. Onufrienko, Walz, Bursch and Perrin will install their seats for re-entry on Endeavour's middeck. Perrin will help the Expedition 4 crewmembers into their seats Monday. Endeavour is scheduled to land at Kennedy Space Center in Florida Monday at 11:59 a.m. CDT.

Onufrienko, Walz and Bursch are coming back to Earth after 181 days aboard the International Space Station. If Endeavour lands on time, Walz and Bursch will set a new record of U.S. spaceflight endurance with 194 days in orbit. Astronaut Shannon Lucid held the previous record of 188 days, set on her mission to Mir in 1996.

The Expedition 4 crew will talk with media representatives from the Fox News Network and TV stations in Ohio and New York in a news conference beginning at 12:38 p.m.

Cockrell and Lockhart will fire Endeavour's orbital maneuvering system engines for 10 seconds today to allow sensors to observe the plume created by the burn to help improve models on the ground.

On board the space station, the Expedition 5 crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - was awakened at 1 a.m. The crew is unpacking and settling into its new home, preparing for a 41/2-month stay in orbit.

The crew of Endeavour will begin a scheduled eight-hour sleep period at 7:23 p.m. today. They are to be awakened just before 3:30 a.m. Monday to prepare for re-entry and landing of Endeavour, concluding a successful mission to the station.

Endeavour crewmembers, Commander Ken Cockrell, Pilot Paul Lockhart, and Mission Specialists Philippe Perrin and Franklin Chang-Diaz, and Expedition 4's Yury Onufrienko, Carl Walz and Dan Bursch, were given the word to back out of deorbit preparations about 10:30 a.m. today.

Endeavour has two landing opportunities at KSC Tuesday. The first begins with the firing of Endeavour's braking rockets at 9:47 a.m. and a landing at 10:55 a.m. CDT. A second opportunity for a Florida landing would see the deorbit burn at 11:24 a.m. and a landing at KSC at 12:31 p.m. CDT. Preliminary weather forecasts call for the possibility of clouds and rain showers in the area of the three-mile landing strip on Tuesday.

The Edwards Air Force Base landing site will be activated Tuesday, though KSC remains the preferred landing location. Forecasts for both KSC and Edwards called for questionable weather that could prevent a Tuesday landing. Endeavour has enough consumables on board to remain in orbit until Thursday.

The first of two Tuesday opportunities to land at Edwards would see a deorbit burn at 12:54 p.m. and a landing at 2 p.m. CDT. For the second opportunity, the deorbit burn would begin at 2:32 p.m. with a landing at 3:36 p.m. CDT.

Endeavour completed all major objectives of its STS-111 flight. It rotated station crews, brought more than 9,000 pounds of equipment and supplies to the station, and in three successful spacewalks gave the station's robotic arm, Canadarm2, a mobile base for future station assembly and maintenance work, and replaced its wrist-roll joint.

Crewmembers aboard Endeavour were scheduled to begin a sleep period at 6:23 p.m. and be awakened at 2:23 a.m. Tuesday.

Meanwhile, the ISS Expedition 5 crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - is still unpacking the supplies and equipment delivered by Endeavour to the station.

Endeavour completed all major objectives of its STS-111 flight. Expedition 5 crewmembers were taken to the station while Expedition 4 crewmembers are coming home. Tons of equipment and supplies were transferred between the two spacecraft and three spacewalks replaced the wrist roll joint of the station's robotic arm, Canadarm2, and gave the arm a mobile base for future station assembly and maintenance work.

Endeavour Commander Ken Cockrell, Pilot Paul Lockhart, and Mission Specialists Philippe Perrin and Franklin Chang-Diaz, and Expedition 4 crewmembers Yury Onufrienko, Carl Walz and Dan Bursch were awakened at 3:23 a.m. by the "The Eyes of Texas," performed by the University of Texas Marching Band. Cockrell and Lockhart hold degrees from that university.

Meanwhile, aboard the ISS, the Expedition 5 crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - is still settling into its new home, unpacking the supplies and equipment delivered by Endeavour to the station.

Houston's Mission Control Center told Endeavour crewmembers, Commander Ken Cockrell, Pilot Paul Lockhart, and Mission Specialists Philippe Perrin and Franklin Chang-Diaz, and Expedition 4's Yury Onufrienko, Carl Walz and Dan Bursch, of the second of two wave offs about 9:35 a.m.

Similar inclement weather on Monday resulted in a wave-off of those landing opportunities. Wednesday offers two landing opportunities at KSC and three at Edwards Air Force Base in California. Forecasters are predicting improving weather at both sites. Endeavour has enough consumables on board to remain in orbit until Thursday, if necessary.

The first of the KSC landing attempts would begin with a deorbit burn at 8:44 a.m. and a landing at 9:53 a.m. CDT (10:53 a.m. eastern.) A second opportunity for a Florida landing would see the deorbit burn at 10:19 a.m. and a landing at KSC at 11:27 a.m. CDT (12:27 p.m. eastern.)

The first of the three subsequent opportunities at Edwards would begin with a deorbit burn at 11:50 a.m. and a landing at 12:58 p.m. CDT. The deorbit burn for the second attempt would be at 1:27 p.m. and a landing at 2:33 p.m. CDT. The third opportunity would see a deorbit burn at 3:06 p.m. and a landing at 4:11 p.m. CDT.

Crewmembers aboard Endeavour are scheduled to begin a sleep period at 5:23 p.m. and be awakened at 1:23 a.m. Wednesday.

All continues to go smoothly aboard the International Space Station in the early days of Expedition 5's residency. Commander Valery Korzun, and Flight Engineers Peggy Whitson and Sergei Treschev, are still unpacking the supplies and equipment delivered by Endeavour.

Rain and thundershowers in the area of the Kennedy Space Center landing site in Florida caused flight controllers to wave off both of Monday's opportunities to bring Endeavour home.

Meanwhile, the ISS Expedition 5 crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - is still unpacking the supplies and equipment delivered by Endeavour to the station and familiarizing themselves with their new home.

Endeavour touched down on Edwards' concrete runway at 12:58 p.m. CDT (10:58 a.m. PDT), concluding a record 196-day stay in space for Expedition 4 crewmembers Yury Onufrienko, Carl Walz and Dan Bursch. The STS-111 flight of Endeavour delivered the Expedition 5 crew - Commander Valery Korzun, Astronaut Peggy Whitson and Cosmonaut Sergei Treschev - to the International Space Station. In addition, the shuttle carried more than 9,000 pounds of equipment and supplies to the station and the crew conducted three spacewalks to expand the station's capabilities.

Endeavour traveled 5,781,115 statute miles since its June 5 launch from KSC's Pad 39A. Today's landing followed weather-related wave-offs on Monday, Tuesday and today because of rain showers, thunderstorms and cloud cover in the area of the Kennedy Space Center, the primary shuttle landing site.

The STS-111 and Expedition 4 astronauts will return to a welcoming ceremony at Ellington Field's Hangar 990 in Houston near the Johnson Space Center around 3 p.m. Central time Friday, June 21. The public is invited.

Meanwhile aboard the International Space Station, the Expedition 5 crew continues to settle into its new home with Whitson beginning investigations with a cell culture experiment today.

For a second day, rain, thundershowers and clouds around the Kennedy Space Center in Florida caused flight controllers to wave off Tuesday's opportunities to bring Endeavour and its crew home.

Similar weather Monday resulted in a wave-off of those landing opportunities. Wednesday offers two landing opportunities at KSC and three at Edwards Air Force Base in California.

All continues to go smoothly aboard the International Space Station in the early days of Expedition 5's residency. Commander Valery Korzun, and Flight Engineers Peggy Whitson and Sergei Treschev are activating equipment, initiating scientific experiments and getting used to the space station environment and routines.

Expedition 5 Commander Valery Korzun, astronaut Peggy Whitson and cosmonaut Sergei Treschev began their 4½-month tour of duty on June 5 when they launched on board space shuttle Endeavour, They arrived on the ISS June 7. Since the shuttle undocked from ISS on Saturday, the new crewmembers have spent time familiarizing themselves with the station and its systems while unpacking the gear that arrived on board with them.

This week the crewmembers started loading unneeded equipment and other trash into the Progress 7 supply ship docked to the aft port of the Zvezda Service Module. That cargo ship is slated to undock from ISS at 3:23 a.m. CDT Tuesday and will be destroyed during entry into Earth's atmosphere. A new unpiloted capsule, Progress 8, loaded with food, fuel, clothing and other supplies for the station crewmembers, is targeted to launch from the Baikonur Cosmodrome in Kazahkstan at 12:36 a.m. CDT Wednesday, and will dock automatically to ISS early June 29. Korzun and Treschev are scheduled to spend time this weekend refreshing their knowledge of the station's backup approach and docking system in preparation for Progress operations next week.

This week Whitson completed operations with the StelSys experiment in the Biotechnology Specimen Temperature Controller (BSTC), which supports investigations in cell biology and tissue engineering in a weightless environment. The BSTC houses stationary bioreactors that maintain samples at a specified temperature in a controlled environment. The StelSys Liver Cell Research experiment, a Space Product Development investigation done under a licensing agreement with StelSys, Inc. of Baltimore, Md., seeks to compare the function of liver cells in microgravity with that of duplicate cells on Earth as a means of learning more about how to maintain the health of humans living and working in space. Whitson's tasks included analyzing the growth media in those bioreactors, replacing the media, preserving and photographing sample cultures, and purging the growth chamber with carbon dioxide to prepare it for its next use. The StelSys samples are stowed in a refrigerator/freezer in the Lab for return to Earth on the next space shuttle assembly mission, STS-112/9A, targeted for launch in August.

Each day station crewmembers are assigned time for physical exercise, using the station's treadmill, bicycle ergometer, or resistive exercise devices, to strengthen the muscles and cardiovascular systems which don't get the workout in weightlessness that they do on Earth. Along with their routine exercise this week, Korzun and Treschev completed two sessions of a Russian-Japanese experiment in which they shot close-up high-definition video of themselves while running on the treadmill. Researchers study the crewmembers' facial features as part of the medical evaluation of a crewmember on orbit.

The ISS Expedition 4 crewmembers --Commander Yury Onufrienko and astronauts Carl Walz and Dan Bursch--completed a 196-day mission when they and their STS-111 crewmates touched down at Edwards Air Force Base in California at 10:58 a.m. PDT Wednesday. Walz and Bursch are now the co-holders of the record for the longest single spaceflight in U.S spaceflight history, 196 days,and Walz' total of 231 days on orbit during his five missions makes him the American astronaut with the most cumulative time in space.

Russian flight controllers commanded the undocking at 3:23 a.m. CDT. Three minutes later, at 3:26 a.m., springs pushed the Progress 7 away from the aft port of the station's Zvezda Service Module. Expedition 5 crewmembers, Commander Valery Korzun, Astronaut Peggy Whitson and Cosmonaut Sergei Treschev monitored the undocking.

Progress engines did the first of two separation burns on command from Mission Control Moscow when it was about 50 yards from the station, at 3:29 a.m. The second was done at 3:35 a.m., with Progress 7 about 275 yards from the station.

Later this morning, at about 6:35 a.m., Russian flight controllers will command Progress 7 to fire its engines in a deorbit burn, which will send it to destruction with its cargo of trash and unneeded supplies and equipment. The spacecraft will feel the first effects of the atmosphere a little after 7:10 a.m. as it begins its fiery descent into the atmosphere.

The undocking clears the way for the arrival of a new Progress. Preparations are being completed at the Baikonur Cosmodrome in Kazakhstan for the launch early Wednesday of Progress 8, which will bring several tons of fuel, equipment and supplies to the space station. It is scheduled to dock with the ISS early Saturday.

The Progress 8 spacecraft lifted off on a Soyuz rocket at 12:37 a.m. CDT. About nine minutes later its solar rays and navigational antennas deployed in response to preprogrammed commands, and the umpiloted cargo carrier was safely in orbit.

Progress 8 is scheduled to dock with the space station early Saturday, where Expedition 5 crewmembers, Commander Valery Korzun, Astronaut Peggy Whitson and Cosmonaut Sergei Treschev, will begin unloading its cargo. The Progress can carry about 7,000 pounds into orbit, including fuel for the Zvezda Service Module's attitude control thrusters.

A series of rendezvous burns by the Progress 8 engines over the next three days will result in its docking to the aft port of the Zvezda Service Module at about 1:25 a.m. CDT Saturday over Central Asia. That port was vacated Tuesday when the Progress 7 was undocked with its load of trash and deorbited to a fiery destruction in the Earth's atmosphere.

The Progress docked to the aft port of the station's Zvezda Service Module at 1:23 a.m. CDT as the two spacecraft orbited about 240 statute miles above Central Asia. Shortly after first contact, hooks and latches engaged between the Progress and Zvezda to lock the two together.

Expedition 5 crewmembers, Commander Valery Korzun, Astronaut Peggy Whitson and Cosmonaut Sergei Treschev, will do leak checks between the Progress and Zvezda before opening hatches at about 4:30 a.m. to gain access to the newly arrived vehicle. The crew will unload its cargo during the coming days.

Progress 8 replaces the Progress 7 cargo carrier at the space station. Progress 7 was undocked early Tuesday and deorbited later that morning. It burned in the Earth's atmosphere with its load of trash from the ISS.

This week, the crew continued to settle into its new home and conduct scientific experiments. Whitson and Treschev worked to activate the Zeolite Crystal Growth Furnace, and Korzun and Whitson performed their first of several monthly sessions with the Pulmonary Function experiment to test their lung capabilities while living in a microgravity environment. Whitson took the first samples from the Advanced Astroculture soybean plant growth experiment.

Expedition 5 Commander Valery Korzun, and Flight Engineers Peggy Whitson and Sergei Treschev had a relatively light week of work; with Sunday and Monday largely rest days after last Saturday’s docking of the Progress 8. July 4 was essentially a holiday in space for the crewmembers, thought they did some work off a generic task list.

Whitson spent much of this morning installing the SUBSA experiment in the glovebox, which has not yet been commissioned for operations. The SUBSA installation will be completed once the MSG is activated.

Earlier this week, crewmembers began unloading the Progress and cataloguing its contents into the computerized, barcode Inventory Management System of the space station. Whitson brought the Medium-rate Communications Outage Recorder (MCOR) in Destiny back to life on Wednesday, after a three-week outage. She checked its fans and replaced a computer docking station. The MCOR records payload data during periods when the station is out of communication with the ground and transmits the data once communications are restored. The outage had no impact on science operations.

Next Wednesday, Korzun and Whitson will be at the controls of the Canadarm2 robotic arm in Destiny, commanding the Canadian-built arm to “walk off” its grapple fixture on the laboratory so that its available latching end effector can grapple a power and data fixture on the recently installed Mobile Base System, the platform mounted on the station’s rail car on the S0 (S-Zero) truss. One end of the arm is already affixed to the Mobile Base System, but the “walk off” of the other end of the arm to the mobile platform will mark another first for station robotic operations. The rail car will eventually move down the truss to be placed in position for the installation of the S1 Truss on the starboard side of the ISS, planned for later this year.

U.S. and Russian timeliners have converged on Aug. 16 and 23 as the two dates for spacewalks planned by Korzun and Whitson, then Korzun and Treschev, to mount experiments on the outside of the station and to install micrometeoroid debris shields on Zvezda. Those are the only two spacewalks planned for the Expedition 5 crew.

On Wednesday, Commander Valery Korzun and Flight Engineer Peggy Whitson commanded the Canadian-built robotic arm to "walk off" its grapple fixture on the Destiny laboratory and grapple a power and data fixture on the Mobile Base System on the S0 truss. The walk-off was the first time the Canadarm2 has been detached from Destiny since it was installed in April 2001. Korzun and Whitson also completed a dry run of the S1 truss installation. The S1 will be brought to the station during STS-112. On Friday, the duo maneuvered the Canadarm2 onto several other MBS grapple fixtures to give engineers on the ground the data they need to prepare for the installation of both the S1 and P1 trusses.

During the week, Korzun and Flight Engineer Sergei Treschev also continued to unload the Progress 8 resupply craft and enter supplies it brought to the station into the Inventory Management System. Korzun and Treschev also spent time doing periodic maintenance activities and installing cargo enclosures in Zarya.

When not working with the Canadarm2, Whitson activated and checked out systems in the MSG and completed the first runs of the Solidification Using a Baffle in Sealed Ampoules experiment in that new facility. Processing in the Zeolite Crystal Growth furnace concluded Friday after 15 days of operations and a new science payload, the Microencapsulation Electrostatic Processing System experiment, will begin next week.

The crew congratulated the designer of the station's Zvezda service module today, the second anniversary of its launch.

Korzun and Whitson worked together for four hours on Monday and another four hours on Tuesday to replace the Desiccant/Sorbent Bed Assembly of the Carbon Dioxide Removal Assembly (CDRA) in the U.S. laboratory Destiny. There are two such beds in CDRA. The one replaced had not functioned properly since its launch in Destiny on Discovery's STS-98 mission in February 2001 because a valve between the desiccant and sorbent sides had stuck in the open position. The second bed continued to function, and a carbon dioxide scrubber in the Russian segment also was available.

Whitson and Korzun overcame or worked around a series of minor difficulties during the removal and replacement. Engineers and flight controllers on the ground are reactivating the Atmosphere Revitalization Rack where the CDRA is situated. The CDRA will be turned on next Tuesday and operated for several days to verify the success of the replacement.

Crewmembers performed an emergency medical operations drill on Wednesday, designed to keep them sharp in emergency medical procedures and to ensure that equipment is optimally stowed and available.

Whitson also worked with a balky spacesuit battery recharger. Her inputs were valuable to engineers on the ground and flight controllers who devised procedures that should fix the problem, the failure of a battery in the device to discharge before receiving a new charge. She also regenerated one of the spacesuit Metox carbon dioxide removal canisters.

Scientific experiments performed by the crew included work with the Microencapsulation Electrostatic Processing experiment, enclosing a drug or drugs in microballoons. Crewmembers also tended the Advanced Astroculture experiment, which grows soybeans in space with an eye to improving their oil, protein or carbohydrate content. The Microgravity Science Glovebox was used in the Solidification Using a Baffle In Sealed Ampoules experiment, designed to understand the motion in melted fluids to improve semiconductors.

All three crewmembers participated on Tuesday in an Educational Outreach project called Toys in Space. They operated toys, among them a boomerang, a jump rope and marbles, to demonstrate scientific principles. The demonstrations were in conjunction with questions from children at the Houston Museum of Natural Science and the American Museum of Natural History in New York City.

Russian officials have decided to perform a reboost of the International Space Station on Aug. 1, to put it at an optimal altitude for arrival of the next Progress unpiloted Russian supply spacecraft, and the next Soyuz crew return vehicle this fall.

Microgravity research included a session with the semiconductor crystal-growing experiment known as Solidification Using a Baffle in Sealed Ampoules, or SUBSA. Whitson set up and activated the experiment in the Microgravity Science Glovebox inside the Destiny laboratory. In the experiment, semiconductor samples are heated to their melting point and allowed to cool and solidify. Whitson downlinked television pictures of the experiment, which thanks to a transparent furnace design allowed scientists to see the solidification of indium antimonide crystals in space for the first time. The objective is to develop techniques for making larger, purer semiconductors for a variety of computer and electronics applications on Earth.

Whitson also took electronic images of soybean plants growing in the Advanced Astroculture experiment package, which scientists on the ground used to confirm that the plants have begun to flower. Scientists hope to develop soybeans with improved oil, protein, or carbohydrate content as a result of this research, which will feature the first seed-to-seed grown of soybeans on orbit.

All three crewmembers worked with biological experiments associated with their upcoming spacewalks on Aug. 16 and 23. They took turns blowing into a tube attached to sensitive instruments on the Pulmonary Function in Flight, or PuFF, experiment, which looks at the effects of spacewalks and long-duration spaceflight on human lung function. They also took background radiation readings that will help to calibrate readings from sensors that will be placed in pockets on the liquid cooling underwear they'll use during the spacewalks.

Korzun and Whitson will make the first foray out of the Russian Pirs docking compartment and airlock to install panels designed to protect the Zvezda living quarters from space debris, as well as a new set of Russian materials samples to be exposed to the rarified atmosphere of atomic oxygen at the station's altitude of 242 statute miles. Korzun and Treschev will make the second excursion, installing similar samples in a Japanese experiment and two additional amateur radio antennas.

The workweek began with removal and replacement of remote power converter modules in the Quest airlock. The modules had been exhibiting signs of malfunction, and although recoverable, these signs led engineers on the ground to recommend their replacement. Korzun and Whitson completed the swap, and flight controllers in Houston confirmed that the new units appear to be working properly. The older units will be returned to Earth for detailed inspection and analysis.

Mission Control also followed up on repair work on the Carbon Dioxide Removal Assembly by Korzun and Whitson. The pair had replaced one of two absorbent beds for the system last week. On Tuesday, flight controllers attempted to activate the replacement bed, which contains Zeolite crystals to absorb the excess carbon dioxide breathed out by the crew. But the replacement bed showed signs of leakage similar to that seen from the original bed, but at a lower rate. Life support systems engineers on the ground suspect there may be another leak elsewhere in the CDRA that was not corrected by the bed replacement, but are still studying the data and considering further options. They verified that the system can still function properly with just one bed in operation. In the meantime, scrubbers in the station's Russian segment continue to provide all of the carbon dioxide removal required by the Expedition 5 crew and visiting taxi crews.

On Thursday, the crew reported hearing "clattering" noises as they ran or walked in place on the Treadmill Vibration Isolation System. As a result, exercise on that equipment was suspended. Instead, the station inhabitants will use a variety of other stationary bicycles and resistive exercise devices to maintain their cardiovascular health and muscle tone. Treadmill experts on the ground are working to replicate the problem on a duplicate TVIS so that they can design an effective repair.

A full-up fire drill and checkout of emergency equipment such as fire extinguishers and portable breathing apparatus made sure that Korzun, Whitson and Treschev are ready to respond in the unlikely event of a fire inside the station.

The crew wrapped up its work week filming demonstrations for Toys in Space, an educational outreach project intended to inspire students to study science, engineering and mathematics so that they can become the next generation of space explorers. They operated toys, such as yo-yos, gyroscopes, soccer balls and a miniature hockey game, documenting the way the toys react in microgravity.

Russian officials conducted routine Progress thruster manifold tests in preparation for a reboost of the International Space Station about 11 a.m. CDT Aug. 1. The reboost will put the station at the best altitude to welcome the next unpiloted Russian Progress supply spacecraft and Soyuz crew return vehicle in September and October.

Scientific research in the Destiny lab this week focused on the Advanced Astroculture (ADVASC) and Solidification Using Baffle in Sealed Ampoules (SUBSA) experiments. The ADVASC plant growth chamber houses the first soybean plant growth experiment ever conducted in space. Photographs taken by Whitson show that the plants have developed flowers and seedpods. Tuesday Whitson performed the third nutrient exchange and gas sample procedure for the experiment. This microgravity research may result in soybeans with improved oil, protein, or carbohydrate content, as well as the secondary metabolites, such as phytoestrogen, of commercial value.

The SUBSA experiment, isolated inside the Microgravity Science Glovebox (MSG), is testing what causes motion in the melted fluids used to create semiconductors and a way to reduce the magnitude of that motion, potentially leading to a reduction in defects in semiconductors in space and on Earth. Wednesday ground controllers at the Payload Operations Center at the Marshall Space Flight Center in Huntsville, Ala., sent a software patch to the MSG system to increase the allowed temperature of a furnace inside the box. The SUBSA samples are heated to their 1,490 degrees Fahrenheit (810 degrees Celsius) melting point. After a successful test run of the empty MSG, Whitson loaded the third set of samples into the experiment Thursday.

The crewmembers began a modified exercise routine this week after engineers decided they should not use the Treadmill Vibration Isolation System until it can be fixed. Investigations by the crew found a problem with one of the many rollers that the treadmill's belt runs along. A ball bearing for the rod supporting the roller has seized and the rod has rubbed against the frame of the treadmill. Engineers are working to develop a procedure and hardware to fix the treadmill that could be sent to the station on the next Progress resupply vehicle in September. The crew can use other various machines onboard including a cycle ergometer and a resistive exercise devise.

Korzun and Treschev worked on a procedure to bring the oxygen-generating Elektron system back to its full capabilities. The Elektron separates water into its oxygen and hydrogen components, venting the oxygen into the cabin for the crew to breathe and sending the hydrogen overboard. The original liquid unit in the system experienced a problem in April and the crew replaced it with a backup unit that has had to run in a manual mode requiring the crew to activate its valves. This week, the crew returned the original liquid unit into the Elektron, but that did not bring the system back online. The crew replaced the original with the backup unit again, restoring manual mode operations.

Operations to test the Mobile Servicing System were partially completed Thursday. Korzun and Whitson maneuvered the space station robotic arm, Canadarm2, into a position enabling cameras to look back on its Mobile Base System and the attached Payload Orbital Replacement Unit Accommodation (POA) grapple fixture. The POA was commanded to go through the motions of grasping a payload while cameras on the end of the robotic arm watched. During a test, the computer software thought the POA motors were running too quickly and put the robotic system in a safe mode. Flight controllers turned the POA on and off and restored Canadarm2's motion. A test run with the motors operating more slowly was successful and the arm was left in place until it will be moved next week into a position to use its cameras to view the first Expedition 5 spacewalk. The remaining checkout procedures will be rescheduled.

Korzun and Whitson will step outside of the Russian Pirs docking compartment and airlock Aug. 16 to install panels designed to protect the Zvezda service module from space debris, as well as a new set of Russian materials samples to be exposed to the harsh conditions of space. Live coverage of the spacewalk will begin on NASA Television at 2 a.m. CDT. Korzun and Treschev will make another spacewalk starting late Aug. 22, installing similar materials samples in a Japanese experiment and two additional amateur radio antennas.

The Progress spacecraft's engines boosted the station by about 5 statute miles to an average altitude of 246 statute miles Thursday. This sets the stage for the arrival of a new Progress and a Soyuz taxi crew, both scheduled to launch from the Baikonur Cosmodrome in Kazakhstan this fall.

This week the crewmembers spent time each day reviewing plans for the spacewalk and checking out the tools and equipment they will use. Next Friday at 2:40 a.m. CDT, Korzun and Whitson will open the hatch on the Russian Pirs docking compartment to begin a 5-hour, 55-minute excursion. They will install protective panels on the Zvezda service module and a new set of samples in a Russian experiment verifying the effectiveness of devices designed to protect the station's exterior from contamination by thruster firings. Live coverage of the spacewalk begins on NASA Television at 2 a.m.

On Thursday Whitson maneuvered the station's Canadarm2 into position for its cameras to capture images of the EVA, the third spacewalk of Korzun's career and the first for Whitson.

Korzun and Treschev will make the second spacewalk of this mission (the first for Treschev) starting late Aug. 22 CDT. They will retrieve samples in a Japanese materials exposure experiment, install two additional amateur radio antennas and inspect a condensate collector. All activities will be on the Zvezda service module.

In conjunction with the spacewalk, Korzun and Whitson today tested their lung function for a Human Life Sciences experiment called PuFF (Pulmonary Function in Flight). Station crewmembers use equipment at the Human Research Facility rack in the Destiny module to gauge their lung function before and after a spacewalk so scientists can judge if there are long-term effects from the time spent in the lower-than-normal air pressure environment of a spacesuit.

Wednesday Whitson reactivated the Microgravity Science Glovebox (MSG) in the Destiny laboratory for a fourth run of the experiment SUBSA (Solidification Using a Baffle in Sealed Ampoules). The experiment, conducted inside a transparent furnace in the MSG, tests what causes motion in melted fluids used to create semiconductors. If that motion can be reduced, the experiment could help lead to reducing defects in semiconductors made in space and on Earth. The crewmembers' routine exercise sessions were scheduled on the bicycle ergometer and a resistive exercise device for most of this week while engineers developed a repair plan for the Treadmill Vibration Isolation System in the Zvezda module. Last week the crew found that a ball bearing for a rod supporting one of the rollers under the tread on that apparatus had seized, and the rod was rubbing against the frame of the treadmill. That rod has now been secured, and the crew is cleared to use the treadmill in a non-motorized, reduced speed mode. Plans are being developed to send repair parts to the station on the next Progress resupply vehicle, targeted for launch Sept. 20.

Tuesday morning all the crewmembers gathered in the Destiny laboratory to answer questions from students at the Maryland Science Center in Baltimore, at the completion of a conference on "Women in Science." The session focused on life in a weightless environment.

This week, Russian officials said the next Soyuz crew return vehicle will be launched to the space station Oct. 28. The three-member taxi crew will spend eight days on the ISS. That crew will return to Earth Nov. 7 on the Soyuz now at the station.

It was the first of two spacewalks for the Expedition Five crew, the third of Korzun's career and the first for Whitson. Today's excursion was the 42nd spacewalk in support of ISS assembly and maintenance and the 17th staged from the station itself. 25 spacewalks at the ISS have originated from visiting space shuttles. While Korzun and Whitson worked outside, Flight Engineer Sergei Treschev tended to station systems and choreographed the spacewalk from inside Zvezda.

After a 1 hour, 43 minute delay to the start of the spacewalk because of a misconfigured valve regulating the operation of the primary oxygen bottles in their Orlan spacesuits, Korzun and Whitson opened the hatch to Pirs at 4:23 a.m. Central time (923 GMT) as the ISS flew over the southern Atlantic Ocean east of the southern coast of South America at an altitude of 230 statute miles. Their first task was to set up tools and unfurl a telescoping crane called the Strela boom from the side of the docking module that is attached to the nadir port of Zvezda.

They pressed ahead to move six micrometeoroid debris shields from a temporary stowage location on the connecting module adapter between the U.S. and Russian segments of the ISS that were delivered in June during the STS-111 mission of the shuttle Endeavour.

One by one, the shields were affixed around Zvezda, designed to provide debris protection for the lifetime of the module. 17 additional shields will be flown to the ISS on future missions to complete the job.

Because of the late start to the spacewalk, Russian flight controllers decided to defer the refurbishment of an experiment on Zvezda called Kromka, designed to collect samples of residue emitted from the module's jet thrusters. That lower priority task and the swabbing of thruster residue from Zvezda's hull for analysis will be conducted on a future spacewalk. It was not immediately known whether Korzun and Treschev would perform those tasks next Friday during the second spacewalk of the Expedition.

After retrieving their tools and stowing the Strela crane, Korzun and Whitson returned to Pirs and closed the hatch at 8:48 a.m. Central time (1348 GMT) to wrap up their excursion.

Korzun will venture outside Pirs one week from today with Treschev to install equipment on the exterior of the Russian module which will facilitate the placement of future payloads and the routing of spacewalkers' tethers and to replace Japanese experiments outside Zvezda which measure the effect of atomic oxygen in low Earth orbit on sample materials. Korzun and Treschev will also install two additional amateur radio antennas outside Zvezda to improve contacts with ham radio operators on Earth.

Whitson completed the first spacewalk of her career last Friday with Korzun, spending four hours and 25 minutes outside the orbiting laboratory. Monday's spacewalk will be Korzun's fourth and Treschev's first.

Korzun and Treschev have a variety of tasks to complete Monday morning, including attaching hardware to the exterior of the Zarya module that will be used for tethers and other equipment during future spacewalks; replacing Japanese materials experiment panels on Zvezda, which measure the effects of atomic oxygen in low Earth orbit and collect small pieces of space debris; attaching new plates for the Russian Kromka experiment, which are used to collect and study the residue emitted by Zvezda's jet thrusters; and installing two additional amateur radio antennas on Zvezda to improve contacts with ham radio operators on Earth. The two spacewalkers will also photograph each of these activities for engineers on the ground.

In preparation for Monday's spacewalk, Korzun and Treschev took part in an experiment called PuFF that is being used to look for any changes in crewmembers' lungs that may occur during a long-duration spaceflight. The two cosmonauts tested their lungs Friday using equipment in the Human Research Facility Rack and will test them again after the spacewalk.

It was the second of two spacewalks for the Expedition Five crew, the fourth of Korzun's career and the first for Treschev. Today's excursion was the 43rd spacewalk in support of ISS assembly and maintenance and the 18th staged from the station itself. 25 spacewalks at the ISS have originated from visiting space shuttles. While Korzun and Treschev worked outside, Flight Engineer Peggy Whitson tended to station systems and choreographed the spacewalk from inside Zvezda.

Whitson and Korzun conducted a 4 hour, 25 minute spacewalk on August 16 to install six micrometeoroid debris shields on Zvezda.

After a slight delay to track down a small pressure leak across the hatch between Zvezda and the Zarya module, Korzun and Treschev opened the hatch to Pirs at 12:27 a.m. Central time (527 GMT) as the ISS flew over Russia at an altitude of 235 statute miles. They went to work right away, installing a frame on the Zarya as a "parking place" for modular equipment to be temporarily stowed during future ISS assembly spacewalks and hardware on Zarya which will better route tethers for spacewalkers working around the Russian segment of the station.

The two Russian spacewalkers then exchanged trays of experiments in suitcase-like devices on Zvezda for NASDA, the Japanese Space Agency, which measure the effect of the space environment on engineering materials.

With that work accomplished, Korzun and Treschev completed a task left over from the previous spacewalk ten days ago. They replaced an experiment on the outside of Zvezda called Kromka, which measures the amount of residue emitted from the module's jet thruster firings. Deflectors previously installed on Zvezda have significantly reduced the buildup of residue on the hull of the module.

The final job for Korzun and Treschev was the installation of two additional ham radio antennas on Zvezda to enhance amateur radio operations in the future. ISS residents frequently conduct conversations with "hams" back on Earth.

After retrieving their tools, Korzun and Treschev returned to Pirs and closed the hatch at 5:48 a.m. Central time (1048 GMT) to wrap up their excursion.

The next series of spacewalks to be conducted at the ISS is planned for October when two shuttle astronauts, Dave Wolf and Piers Sellers, conduct three excursions from the Quest Airlock on the STS-112 mission aboard Atlantis to help install and activate the S1 (Starboard One) truss segment, further expanding the station's backbone.

Commander Valery Korzun and Flight Engineer Sergei Treschev completed a 5-hour, 21-minute spacewalk Monday morning, swapping out Japanese space exposure experiments and a Russian experiment measuring jet thruster residue on the shell of the Zvezda Service Module. Flight Engineer Peggy Whitson kept everything running smoothly and helped coordinate her crewmates' activities from inside. She also helped take post-spacewalk readings on how her crewmates' lungs were functioning after working in the lowered pressure of their spacesuits, part of an ongoing study.

Then research took center stage again as Whitson cleaned up the Microgravity Science Glovebox and prepared it to resume experiments studying semiconductor formation in space. After a recent fifth experiment run, a quartz sample tube broke inside the glovebox enclosure. Whitson used a vacuum tube and fan system to remove and secure any particles left inside the box.

Whitson also downlinked a video tour of the U.S. Destiny laboratory module for NASA's Marshall Space Flight Center, where station research is coordinated by the Payload Operations Control Center. Whitson highlighted some of the two dozen experiments that she and her crewmates have been conducting during their first three months in orbit. Thirteen of the 24 phone booth-sized racks inside Destiny are dedicated to science investigations including a wide variety of experiments in human life sciences, physical sciences, commercial space product development and Earth observation, as well as education and technology demonstrations.

Friday, Whitson worked in the Quest airlock module, servicing the American spacesuits and recharging their batteries to prepare for upcoming tests next week. She also partially removed the Express 2 experiment rack in Destiny to gain access and replace a balky smoke detector before the crew began a three-day break over the Labor Day holiday.

Beginning work on Tuesday, following the Labor Day holiday, Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev charged and discharged batteries used in the U.S. extravehicular mobility unit spacesuits in preparation for three spacewalks that will originate from the station's Quest airlock module. Whitson also did some troubleshooting on the battery charging assembly associated with that task.

The entire crew participated in emergency training sessions, practicing their assignments and responsibilities in the event of either an emergency depressurization of a station module, or a medical emergency affecting a crewmember. The training sessions are scheduled periodically to make sure the crew is always prepared to react quickly and effectively in the event of an emergency.

Whitson resumed research in the Destiny Laboratory and its new Microgravity Science Glovebox, conducting two runs with an experiment studying semiconductor formation in space. That experiment, Solidification Using a Baffle in Sealed Ampoules, uses a special furnace to control the initial melting, fluid motion and bubbles as the crystals form in an effort to make larger, purer semiconductor crystals. Two more samples will be processed before Whitson reconfigures the glovebox for the next, the Pore Formation and Mobility Invesigation, which focuses on the bubbles that often become trapped in a metal or crystal sample and diminish the material's strength and usefulness.

Thursday was robotics day on the station, with Whitson and Korzun taking turns at Canadarm2's controls both to increase their proficiency and to continue to check out the Mobile Base System on the station's truss structure. The pair "flew" the arm into position so that the Latching End Effector (LEE) of the arm could look directly into the LEE of the Payload and Orbital Replacement Unit Accommodation (POA), and vice versa. This allowed television cameras to downlink views of the snare and latching mechanisms for flight controllers and engineers to inspect.

Next, they moved the arm in a survey of the Mobile Base System and its four Power and Data Grapple Fixtures (PDGFs). Once the survey was complete, they grappled and ungrappled the fourth and final PDGF to be checked out. All of the major objectives of the arm operations and grapple fixture checkout were successful.

Maintenance was the major activity Friday, and the crew powered down about half of Destiny's systems in order to replace a Remote Power Control Module (RPCM) which switches power to various systems on the station. The systems power down and replacement of the module went well, and flight controllers were restoring power to the systems that had been shut down as the crew began preparing for bed Friday afternoon.

This morning Expedition Five Flight Engineer Peggy Whitson set up and activated the ultrasound equipment at the Human Research Facility rack in the Destiny laboratory, then with guidance from flight surgeons in Houston, used it on herself to capture live video images for more than four hours. The ability to capture and downlink ultrasound imagery from orbit expands the kinds of medical research that can be conducted in space by scientists on Earth, and could offer physicians the chance to diagnose ailments in space station crewmembers earlier than they could otherwise. This possibly could improve the chances of effectively treating the problem without requiring an emergency deorbit of the crew and abandonment of the station.

Whitson completed another research milestone on Wednesday when she removed the last sample of the experiment known as SUBSA (Solidification Using Baffle in Sealed Ampoules), the first science project conducted inside the Destiny lab's new Microgravity Sciences Glovebox. Investigators observed via videotape as semiconductor materials were melted inside a transparent furnace. They are investigating methods for reducing the magnitude of motions in those melting materials as a means of reducing defects in the manufacture of semiconductors. The next MSG experiment, which begins operation next week, is PFMI (Pore Formation and Mobility Investigation), in which scientists will observe the formation and movement of bubbles trapped in melting metal and crystal samples, which might diminish material strength and effectiveness.

Thursday, Expedition Five Commander Valery Korzun and Whitson used the station's Canadarm2 to visually examine the Common Berthing Mechanism on the nadir (Earth pointing) side of the Unity module. The examination was prompted by the discovery of some foreign object debris on the CBM of the Leonardo Multi-Purpose Logistics Module that was docked to Unity during the most recent shuttle mission in June. During a three-hour procedure, the station crewmembers gathered close-up views of Unity's berthing port with its protective petals closed and open. Specialists in Houston are reviewing the images along with crewmember descriptions to determine if any action is required.

Wednesday night Russian flight controllers commanded a firing of thrusters on the Progress cargo craft docked to the aft end of Zvezda, raising the station's average altitude by 1.5 nautical miles to 243 statute miles (391 kilometers). The reboost sets the stage for the arrivals of a new Progress resupply ship, targeted to launch from the Baikonur Cosmodrome in Kazakhstan Sept. 24, and a new Soyuz rescue craft, planned to launch on Oct. 28 carrying a "taxi" crew consisting of Russian cosmonaut Sergei Zalyotin and European Space Agency astronaut Frank De Winne of Belgium.

Along with getting time for rest and family conferences last weekend, the station crewmembers fashioned a temporary grounding strap for the Active Rack Isolation System in the Destiny laboratory's Express Rack No. 2 using standard grounding straps found in the lab's zero-g stowage racks. This temporary repair, permitting ARIS activation for operations recalibration, became necessary when the original strap became frayed. New hardware to finalize this repair is being scheduled for delivery to the station on the next shuttle flight.

The shuttle that next will visit the International Space Station moved to Launch Pad 39B at the Kennedy Space Center in Florida Tuesday for final preparation for the next assembly mission (9A). STS-112 is targeted for an Oct. 2 launch on a flight to install the next component of the station's Integrated Truss Structure, the S1 Truss, during three planned spacewalks. The move to the launch pad was completed following replacement of bearings in the Jacking, Equalization and Leveling cylinders of shuttle Crawler Transporter No. 2.

Next week Korzun and Whitson are expected to return to maintenance of the Carbon Dioxide Removal Assembly in the Destiny laboratory, which is still scrubbing the station's environment of carbon dioxide despite indications of interior leaks. Troubleshooting by flight controllers in Houston led to the conclusion that the desiccant valves in the Desiccant/Sorbent Bed Assemblies are seated properly, and that a leak is likely in one of the hydroflow lines; a visual inspection of that area by Whitson confirmed the analysis. Time should be scheduled for Korzun and Whitson next week to open the system rack housing CDRA, as they did when they replaced one of the sorbent bed assemblies in July, to make repairs.

The problem was an elusive leak. Initial reports indicated the repair was a success. On Thursday flight controllers at Mission Control Center activated the device for a 24-hour run. Friday morning they said telemetry indicated it is capable of functioning on both its sorbent beds for the first time since it arrived on the station.

Whitson was named NASA ISS science officer Monday during a space-to-ground conversation with NASA Administrator Sean O'Keefe, speaking with her from the International Space Station Flight Control Room in the Mission Control Center. O'Keefe said it was time to increase the station's main mission, scientific research.

Through the week, Korzun and Treschev spent time each day loading the Progress 8 unpiloted supply spacecraft. It will undock from the station on Tuesday with its cargo of trash and unneeded equipment and supplies. After about two weeks during which Russian flight controllers will use its cameras capture and downlink images of smog and smoke over northeastern Russia, it will be deorbited to burn up in the Earth's atmosphere. NASA TV coverage of the 8:58 a.m. CDT undocking will begin at 8:30 a.m. Coverage of the docking of Progress 9, scheduled to reach the aft docking port of the Zvezda Service Module at 12:07 p.m. on Sept. 29, will begin on NASA TV at 11:30 a.m. that day. Progress 9 is to be launched from the Baikonur Cosmodrome in Kazakhstan Sept. 25.

On Tuesday Whitson activated the lab's Microgravity Science Glovebox in preparation for a new series of experiments. Those experiments called Pore Formation and Mobility Investigation (PFMI) melt a transparent substance to study how bubbles form and move in molten materials. She activated the first in that series of experiments on Thursday.

Also on the crew's schedule was packing of items to be returned to Earth on the shuttle Atlantis. The spacecraft is scheduled to launch no earlier than Oct. 2 on STS-112, bringing the Starboard 1 (S1) Truss to the station. Atlantis crewmembers will do three spacewalks during the shuttle's visit, focusing on connecting fluid, power and data lines between the S1 and the rest of the station. The spacewalks will be performed from the station's Joint Airlock, and E5 crewmembers devoted some of their attention this week to spacewalk preparations.

Flight controllers did a major exercise with the station's Canadarm2 on Wednesday. The arm is functioning well after replacement of its wrist-roll joint by spacewalkers during the STS-111 flight in June. This exercise involved simulating a failure - essentially turning off power to an arm joint -- then devising a way to work around the problem. The exercise was completed satisfactorily.

Late in the week, the crew completed repressurization of the station's atmosphere with oxygen from Progress 8.

Friday activities included additional work toward arrival of Atlantis, packing transfer items and talking by radio with Atlantis crewmembers about the spacewalks. Friday science focused on the Advanced Astroculture experiment, which looks at soybean growth in space and wrapping up the first of the PFMI experiments.

As science activity, station maintenance and crew medical and health activities, including about two hours of exercise for each member daily, continued through the week, Korzun, Whitson and Treschev did manage to take time out on Tuesday to talk with students at Ashland, Wis., area schools. Crewmembers showed a video of exercise devices aboard the station and answered questions from the students.

Expedition 5 Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson, and Flight Engineer Sergei Treschev have spent the early part of the week preparing for the departure of the Progress 8 vehicle and the arrival of the next, and worked with science experiments in the U.S. Laboratory Destiny.

Also, the crew continues preparations for the arrival of Space Shuttle Atlantis and the STS-112 crew scheduled for launch between 2 p.m. and 6 p.m. EDT on Oct. 2 by pre-packing items to be brought home upon Atlantis' departure.

After the Progress 8 spacecraft - loaded with trash and unneeded equipment - was undocked Tuesday, it was parked a safe distance from the station where it will remain for about two weeks while Russian flight controllers use its cameras to document smog and smoke over northeastern Russia.

The STS-112 mission will deliver the Starboard 1 (S1) Truss to the station, with final connections being conducted during three spacewalks by shuttle crewmembers. The Expedition Five crew devoted some of its attention this week to preparing the station's Airlock Quest for those spacewalks.

Also, in preparation for the arrival of the station's newest component, Whitson will practice with the Canadarm2 Thursday, moving the robotic arm through the same tasks it will see during the installation of the S1 Truss.

As science activity, station maintenance and crew medical and health activities continued, Korzun, Whitson and Treschev took part in two educational events with school children in Iowa and in Japan.

The Progress 9 vehicle linked up to the aft docking port of the Zvezda Service Module of the ISS at 12:01 p.m. Central time (1701 GMT) as the two spacecraft flew over Central Asia after a four-day flight following its launch Wednesday from the Baikonur Cosmodrome in Kazakhstan. The automated docking went off without a hitch as Expedition 5 Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson, and Flight Engineer Sergei Treschev viewed the arrival of the new capsule from inside Zvezda. A few minutes later, hooks and latches closed between the two vehicles to form an airtight seal.

Korzun was prepared to take over manual control of the Progress for the docking in the event its automated rendezvous system did not work, but the linkup was executed flawlessly.

The crew was scheduled to open hatches between Zvezda and Progress this afternoon and will begin unloading supplies from the craft on Monday.

Some of the supplies include clothing and personal items for the Expedition Six crew - Commander Ken Bowersox and Flight Engineers Nikolai Budarin and Don Pettit - who will be launched aboard Endeavour on the STS-113 mission in November to replace Korzun, Whitson and Treschev following the completion of their 5 1/2 month mission.

The older Progress 8 vehicle, which arrived at the ISS in June and which was undocked on Tuesday, remains in orbit a safe distance away from the station, spending another 10 days aloft to enable Russian flight controllers to document smog and smoke over northeastern Russia through its cameras.

The Progress docking clears the way for the launch of Atlantis on the STS-112 mission Wednesday to deliver the 14-ton Starboard 1 (S1) Truss to the station. A Wednesday launch would result in Atlantis' docking to the ISS Friday. Commander Jeff Ashby, Pilot Pam Melroy and Mission Specialists Dave Wolf, Sandy Magnus, Piers Sellers and Fyodor Yurchikhin are in the final stages of their prelaunch preparations.

Preparations included powering down Mission Control Houston as Lili approached the Gulf Coast. The storm was expected to take a more northerly heading beginning late today or early Thursday, leading to a landfall on the Louisiana coast. Forecasters say it will be at least midnight before the storm's course becomes more clear, so preparations continue at Johnson Space Center.

The hurricane preparation in Houston also led to a delay in the launch of Atlantis to the on STS-112 flight to the space station. Atlantis, bringing the Starboard 1 Truss segment to the station, is now scheduled to launch no earlier than Monday. The Houston Support Group is an organization that includes flight controllers and others based at Mission Control Moscow in the Russian capital's suburb of Korolev. They will continue reduced flight control operations communicating with the orbiting laboratory using Russian ground stations augmented by U.S. ground stations. The group in Russia remains in close contact with the flight control team in Houston, which is using other Johnson Space Center facilities.

Aboard the orbiting laboratory, Expedition 5 Commander Valery Korzun, NASA International Space Station Science Officer Peggy Whitson, and Cosmonaut Sergei Treschev, were told of the shift Tuesday afternoon CDT, near the end of their working day. They were told a little after 9 a.m. today of the delay in Atlantis' launch.

The station's 240-foot solar wing assembly is no longer tracking the sun, because of reduced monitoring capabilities on the ground. As a result of decreased power production, some non-essential equipment aboard the station was turned off to reduce power consumption. Otherwise, the crew is working through an essentially normal day on the orbiting laboratory.

Houston flight control of the station was resumed about 6 p.m. Thursday. That was a little over 12 hours after reactivation of MCC Houston, begun when it became apparent that Lili would not hit the area.

Members of the Houston Support Group in Mission Control Moscow had taken over control of the station's U.S. segment early Wednesday, when Lili was churning in the Gulf of Mexico and its landfall uncertain. The group followed a contingency plan setting up a Backup Control Center (BCC) in MCC Moscow. They communicated with the station using Russian and U.S. ground stations, and remained in close telephone contact with flight control teams gathered in a conference room at Johnson Space Center.

While the BCC was in operation, high-rate data downlink from the station was not available. Since they were unable to monitor the movement of the solar arrays, flight controllers put them in a fixed position. As a result, power to some station payloads and systems was reduced. The repowering process is being carried out largely by flight controllers.

Russian and Houston-based station officials praised the smoothness of the handovers to the BCC and back to Mission Control Houston, as well as the performance of the BCC itself. The Houston Support Group, U.S. flight controllers and others based in Mission Control Moscow, and Mission Control Houston practiced for just such a contingency less than three weeks ago.

As Lili approached on Wednesday, power at MCC Houston was turned off in a carefully planned sequence, and its electronic equipment covered with waterproof plastic sheets. Today, operations are essentially back to normal.

The hurricane precautions in Houston led to a delay in the launch of Atlantis on the STS-112 flight to the space station. Atlantis, bringing the Starboard 1 Truss segment to the station, is now scheduled to launch on Monday. Preparations for the launch are going smoothly.

The situation also caused the Russians to cancel a scheduled Wednesday test of thrusters on Progress 9, the unpiloted cargo vehicle that docked to the rear of the station's Zvezda Service Module on Sunday. They also canceled a station reboost by the Progress, which had been scheduled for today.

The Expedition 5 crew, Commander Valery Korzun, NASA International Space Station Science Officer Peggy Whitson, and Cosmonaut Sergei Treschev, had a relatively quiet Friday to wind up their hurricane-impacted workweek about 240 statute miles above the Earth's surface. Science activities and station maintenance continued. The crew also devoted some time to unloading the Progress 9 unpiloted supply spacecraft docked at the back of the station's Zvezda Service Module.

Aboard Atlantis are Commander Jeff Ashby, Pilot Pam Melroy and Mission Specialists Dave Wolf, Sandy Magnus, Piers Sellers and Russian cosmonaut Fyodor Yurchikhin. A small television camera on the shuttle's external fuel tank captured a unique view of the Earth as Atlantis headed into orbit.

Less than nine minutes after launch, Atlantis and its crewmembers settled into orbit and work began to prepare for a planned 11-day mission.

As Atlantis headed toward space, on board the ISS, Expedition 5 Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev were completing their 124th day in orbit and their 122nd day aboard the station. At the time of Atlantis' launch, the space station orbited 240 statute miles above the Pacific Ocean west of Ecuador.

Atlantis' crew is setting up equipment on board and preparing to open the shuttle's payload bay doors to begin orbital operations prior to heading to bed just before 9 p.m.

Atlantis is scheduled to dock to the station at about 10:30 a.m. Wednesday, setting the stage for the installation of the S1 truss on the starboard side of the S0 truss, which arrived at the ISS in April. Three spacewalks are scheduled during the mission by Wolf and Sellers to help activate the new truss' systems. The S1 truss is the fourth of 11 truss segments which will form the structural backbone for the station and provide the cooling and support for new solar arrays to be delivered to the station next year.

The shuttle crew will be awakened at 4:46 a.m. Tuesday to begin its first full day in orbit and to prepare for Wednesday's docking.

Aboard Atlantis, Commander Jeff Ashby, Pilot Pam Melroy and Mission Specialists Dave Wolf, Sandy Magnus, Piers Sellers and Cosmonaut Fyodor Yurchikhin were awakened at 4:46 a.m. to the song "Venus and Mars" by Paul McCartney and Wings. It was for Wolf, requested by his wife, Tammy.

The Expedition Five crew, Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Cosmonaut Sergei Treschev – in their 18th week in space – were awakened at 3 a.m. Atlantis' crew will be their first visitors since June. They are shifting their sleep schedules to prepare for the week of docked operations with Atlantis.

Today, Atlantis' crew focuses on preparations for rendezvous and docking by checking out the necessary tools. The crew also will prepare the spacesuits to be used during the three planned spacewalks by Wolf and Sellers scheduled for Thursday, Saturday and Monday. The shuttle's robotic arm also will be checked out and used to survey the payload bay, including the Starboard 1 (S1) Truss.

This afternoon the centerline camera will be mounted in the Orbiter Docking System hatch to assist Ashby as he guides the orbiter in for docking. The crew then will extend the docking ring, which makes first contact with the station.

The station crew is continuing with science operations and standard exercise activities. Whitson is working with radiation monitors for Wolf and Sellers, who will conduct the spacewalks to hook up the S1 after it is lifted from Atlantis' cargo bay and installed on the station Thursday. She will activate the monitor's badge readers and do pre-spacewalk background readings.

Atlantis' crew is scheduled to begin an eight-hour sleep period at about 6:30 p.m. today.

After arising at 4:46 a.m. CDT, the crew began its first full day on orbit with Pilot Pam Melroy assisting Mission Specialists Dave Wolf and Piers Sellers in a checkout of spacewalk suits and equipment. Commander Jeff Ashby worked with the prime robotic arm operator, Mission Specialist Sandy Magnus, to verify the arm's readiness. Ashby and Magnus powered up the arm for a video survey of Atlantis' payload bay.

In preparation for Wednesday's rendezvous and docking with the station at 10:24 a.m., the crew set up the orbiter docking system's centerline camera, extended the orbiter's spring-loaded ring that will make first contact, and checked out rendezvous tools.

The crew successfully completed three Orbital Maneuvering System burns to boost the orbiter into the station's orbit and refine its approach path to the station.

Science already is getting underway on Atlantis with Wolf leading check-out activities for the SHIMMER experiment sponsored by the Naval Research Lab. The Spatial Heterodyne Imager for Mesospheric Radicals experiment uses an ultraviolet sensing camera to observe the Earth's atmosphere at 40-90 kilometers looking for possible ozone loss. The experiment proved a bit balky, but with help from Mission Control the crew worked out steps to ready the gear for observations during the mission.

Meanwhile, the space station residents readied their home for the first visitors in the123 days since their arrival at the vehicle. Peggy Whitson and crewmates Valery Korzun and Sergei Treschev have been prepacking materials to return on Atlantis and to make room for about 7,500 pounds of gear arriving at the station.

Whitson has been sending letters describing her life on the International Space Station back to Earth over the last few months. Her most recent letter describes her anticipation and preparations for the shuttle visitors.

Both crews will head for sleep two hours earlier than Monday at 6:46 pm to get plenty of rest before Wednesday's busy day. Rendezvous operations begin at 5:06 a.m., with station docking scheduled for 10:24 a.m. Hatch opening between Atlantis and the station is expected at 12:36 p.m.

Shortly after the musical wakeup call to the crew at 2:46 this morning – Tina Turner's "The Best" for Commander Jeff Ashby from his wife, Paige – the shuttle crew focused its attention on the rendezvous and docking procedures that will culminate with the orbiter docking to a port on the U.S. Destiny Lab of the station.

The Terminal Initiation burn preceding the final approach is planned for 8:04 a.m. and occurs with the two spacecraft 50,000 feet apart. That is followed by a series of four small correction burns, which set the stage for Ashby's taking manual control of Atlantis' thruster jets as he looks out the overhead and rear windows of the flight deck. He will fly Atlantis to a point 600 feet below the station, then begin a quarter circle alignment of the orbiter's docking system and Destiny, which will place the shuttle about 300 feet in front of the station.

Assisting with the rendezvous using lasers and computers are the remaining shuttle crewmembers, including Pilot Pam Melroy and Mission Specialists Dave Wolf, Sandy Magnus, Piers Sellers and Russian cosmonaut Fyodor Yurchikhin.

Awaiting the arrival of Atlantis are the three station crewmembers – Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev – in their 126th day in space.

Thursday will see the installation of the station's newest component – the Starboard 1 (S1) Truss – and shortly thereafter, the first of three planned spacewalks will begin by Wolf and Sellers to connect power, data and fluid lines between S1 and the station.

Crew sleep is set to begin about 6:30 this evening.

All efforts pointed toward the deployment and installation of the Starboard One (S1) Truss. Pilot Pam Melroy, Space Station Commander Valery Korzun, and Mission Specialists Dave Wolf, Piers Sellers, and Fyodor Yurchikhin configured the spacesuits for Thursday's spacewalk. Mission Specialist Sandy Magnus and NASA ISS Science Officer Peggy Whitson reviewed robotic arm operations for moving the new truss segment into place. Sergei Treschev, ISS Flight Engineer, participated in the safety briefing for the station visitors.

Thursday, Magnus and Whitson will use the Canadarm2 from inside Destiny to grapple the huge S1 Truss, take it out of Atlantis' payload bay and move it into position at the starboard end of the S0 Truss. After the segments are soft-mated, capture bolts will make the mating solid. With the truss firmly attached to the station, the spacewalkers will exit the station.

Tomorrow's EVA begins three days of spacewalks – Thursday, Saturday and Monday - at the station-shuttle complex. Shuttle and Mir veteran Wolf and space rookie Sellers will perform the EVAs, which are primarily focused on the installation and hookup of the S1 segment. In Thursday's six-hour spacewalk, Wolf and Sellers will connect power, data and fluid umbilicals between the segments; install a camera and antenna assembly; and release a number of launch restraints. Wolf will ride on the end of the robotic arm for most of the excursion, while Sellers will be a "free floater" moving around the truss structure.

Tonight the crew is scheduled to begin its sleep period at 6:46 p.m. with the wake-up call to sound at 3:16 a.m. Thursday.

Expedition Five's Peggy Whitson and Atlantis' Sandy Magnus used the station's Canadarm2 robotic arm to grapple the 45-foot-long, 14-ton S1 structure, remove it from Atlantis' cargo bay and move it to the starboard end of S0. Motorized bolts locked the two truss segments together at 8:36 a.m. CDT.

Wolf and Sellers ventured outside the station's Quest airlock at 10:21 a.m. Their first task was to connect power, data and fluid lines between the S0 and the S1 trusses. As Wolf worked to accomplish this task, Sellers, on his first spacewalk, released the locks on three folded-up radiators mounted to the S1, allowing S1's radiators to be oriented for optimal cooling

Wolf and Sellers then worked together to install a new S-band antenna assembly. Wolf, attached to the end of the station robotic arm, moved the antenna into position. He then tightened stanchion bolts to lock the antenna into place near the end of the S1 Truss where it connects to the S0 as Sellers held it in place. The new component will increase the S-band data and voice communications capability from the space station to ground controllers.

The duo then went to work releasing restraints that had held the Crew and Equipment Translation Aid (CETA) cart to the S1 for launch and configure its brakes. The CETA cart, a handcar that rides along rails on the station's truss, can be used to move spacewalkers and equipment.

Installation of the S1's outboard nadir external camera was the final major task of the spacewalk. The camera, launched on Atlantis' middeck, is the first of two that will be installed on S1. They will be used as situational awareness tools for spacewalkers and robotic arm operators.

Throughout the spacewalk, Pilot Pam Melroy was inside, offering guidance and advice to the spacewalkers and keeping them on schedule. She had help with arm operations and spacewalk guidance from controllers in the International Space Station Flight Control Room because the spacewalk originated out of the station's Quest airlock. Shuttle Commander Jeff Ashby operated the shuttle robotic arm, providing camera views for documentation.

Following an inventory of the tools they used during the spacewalk and cleanup activities, Wolf and Sellers re-entered Quest. Airlock repressurization began at 5:22 p.m., signaling the end of the spacewalk.

Expedition Five's Peggy Whitson and Atlantis' Sandy Magnus will use the station's Canadarm2 robotic arm to install the 45-foot long, 15-ton structure beginning about 5:30 this morning. Simultaneously, Astronauts Dave Wolf and Piers Sellers will prepare for the first of three spacewalks to attach plumbing, data and electrical lines to bring S1 to life. They plan to exit the Quest Airlock at about 9:40 a.m. and can easily be identified while outside. Wolf will wear a suit with solid red stripes, while Sellers will wear an all white spacesuit.

Throughout the spacewalk, Pilot Pam Melroy will be inside offering guidance and advice to the spacewalkers and keeping them on schedule. Shuttle Commander Jeff Ashby will operate the shuttle robotic arm providing camera views for documentation.

Following grapple of the S1, Magnus and Whitson will move it into position at the starboard end of the first truss segment where it will be secured in place by four remotely operated bolts. That first segment was delivered on a shuttle flight earlier this year.

In addition to hooking up power, data and fluid lines, Wolf and Sellers will release locks on a beam allowing S1's radiators to be oriented for optimal cooling. They also will deploy an antenna and release restraints on a handcar, which can be used to move spacewalkers and equipment along the truss. The next spacewalk, or Extravehicular Activity (EVA) is planned for Saturday to continue hooking S1 connections to the station.

S1 is the third of what will be 11 segments of the Integrated Truss delivered to the station. The truss eventually will stretch 356 feet from end to end and will support four huge solar wing assemblies, one pair of which is already atop the station's P6 Truss. The truss also will support cooling radiators and the first railroad in space, capable of carrying the robotic arm to assembly and maintenance sites around the station.

The workday began at 3 a.m. with a musical wakeup call to Atlantis' crew from Mission Control, Houston. The "medley of childhood songs" was played for Magnus from her family. The Expedition Five crew, Commander Valery Korzun, Whitson and Cosmonaut Sergei Treschev, woke aboard the station at the same time.

The crew is scheduled to go to bed about 8 o'clock this evening.

On Thursday, crewmembers attached the 14-ton, 45-foot Starboard One (S1) truss to the station, using the station's Canadarm2 operated by Atlantis' Sandy Magnus and NASA ISS Science Officer Peggy Whitson. That was followed by the first of three planned spacewalks by Dave Wolf and Piers Sellers to complete a series of tasks, including connecting power lines to the station.

The spacewalk lasted 7 hours, 1 minute and brings the total time for ISS assembly via Extravehicular Activity (EVA) to 272 hours, 45 minutes.

In addition to the time off and transfer operations, Wolf and Sellers will prepare the tools and other equipment for use during tomorrow's second spacewalk. Just before their evening meal, crewmembers will gather to review Quest Airlock procedures for the spacewalk, which is expected to begin about 9:40 a.m. Saturday.

The crew will take part in two interviews today. First, the three Russian crewmembers – Expedition Five Commander Valery Korzun, Expedition Five Flight Engineer Sergei Treschev and STS-112 Mission Specialist Fyodor Yurchikhin – will discuss the mission with Russian press beginning at 10:46 a.m. Later in the day at 1:56 p.m., Wolf, Sellers, Magnus and possibly other crewmembers will be interviewed by CBS Radio, Fox News and the Cable News Network (CNN). Both interviews can be seen on NASA Television.

Today's wakeup call to Pilot Pam Melroy and the rest of Atlantis' crew came at 3:46 a.m. "Oh Thou Tupelo," performed by the Wellesley College Choir, was for Melroy, a 1983 graduate. The station crew woke up about 4:15 a.m. today.

The Atlantis and ISS complex is orbiting the Earth every 92 minutes at an altitude of 244 statute miles.

The spacewalk began at 9:31 a.m. CDT and ended about a half-hour early at about 3:35 p.m. CDT for an official duration of six hours, four minutes. About six and a half hours had originally been allotted for the spacewalk, the second of three ventures outside the station planned for Wolf and Sellers during STS-112 to set up the new station S1 (S-One) truss segment delivered by Atlantis.

The duo prepared a new handcar system for future use on the station's truss-mounted railway. Called the Crew and Equipment Translation Aid, the car will allow astronauts to propel themselves, maintenance and construction equipment hand-over-hand along what eventually will be a 100-yard railway atop the station's truss. The spacewalkers also installed 22 Spool Positioning Devices (SPDs) on station ammonia cooling line connections, devices that will prevent a possible condition that could lock up those connections, preventing them from being opened if needed.

Two more such devices were to be installed during the spacewalk, bringing the total to 24, but they were not attached. Due to a different configuration than anticipated on the two line connections in question, the additional two SPDs would not have fit properly. However, space station engineers and managers have determined those two connections are in a satisfactory condition and will not require any further work.

Other work included the installation of an additional exterior station television camera outside of the Destiny Laboratory; hooking up an ammonia supply for lines to a radiator on the new truss segment that will be deployed Monday afternoon; and checking equipment that will be used to add the next starboard truss segment to the station in the fall of 2003.

During today's spacewalk, STS-112 Mission Specialist Sandy Magnus and ISS Science Officer Peggy Whitson operated the station's Canadarm2 robotic arm, using it to position the spacewalkers at various times. Prior to today's outing by Wolf and Sellers, Atlantis Commander Jeff Ashby and Pilot Pam Melroy fired the shuttle's small steering jets periodically over the course of an hour to boost the altitude of the shuttle and station by about 4 statute miles. The shuttle will perform another boost of altitude for the complex tomorrow, raising it an additional 2 miles.

The station and shuttle crews will begin a sleep period at 7:46 p.m. CDT and awaken at 3:46 a.m. CDT Sunday.

The Extravehicular Activity, or EVA, is set to begin about 9:40 this morning and is planned to last about 6 1/2 hours. It includes installation of devices to prevent pressure buildup in line fittings; connecting cooling system lines; removing launch restraints from a radiator which will be deployed Sunday, and installing a second camera.

The Spool Positioning Devices (SPDs) are designed to prevent pressure buildup in Quick Disconnect fittings, which could make it impossible to disconnect fittings, if necessary. Sellers and Wolf will install 24 of the devices – most of which are on ammonia lines – during the spacewalk.

Sellers, in the all-white spacesuit, will ride the station's robotic arm to the S1 Truss worksite to hook up nitrogen lines used to pressurize the ammonia system, while Wolf, wearing the suit with red stripes, releases launch restraints on the Crew and Equipment Translation Aid – a handcar on the truss rails. Peggy Whitson, NASA ISS science officer, and Atlantis' Sandy Magnus will operate the robot arm. As with the first spacewalk Thursday, Pilot Pam Melroy will choreograph the EVA from Atlantis' flight deck.

Prior to the spacewalk, Commander Jeff Ashby and Melroy will gently raise the altitude of the station by firing small thrusters on Atlantis. This reboost maneuver will increase the altitude of the complex from 238 statute miles (383 kilometers) to 242 sm (389 km).

Atlantis' crew was awakened at 2:46 a.m. today by the song "Push It," performed by the group Garbage. It was for Sellers, requested by his family. The station crew woke up about 30 minutes later.

Atlantis and station crewmembers are scheduled to go to bed about 7:30 tonight.

Dave Wolf and Piers Sellers once again will conduct the spacewalk out of the Quest Airlock beginning about 9:40 this morning. It is the 46th spacewalk devoted to the assembly and maintenance of the station. Today they will focus on the removal and stowage of launch support brackets no longer required; installation of additional clamps on fittings to prevent pressure buildup in fluid lines; install an attach bracket for a future station truss element; and remove a balky bolt preventing activation of a cable cutter on the Mobile Transporter.

Ahead of the spacewalk, Atlantis' thrusters will again be used to gently raise the station's altitude another couple of miles. The reboost lasts about 35 minutes and sets the stage for the arrival of a Russian Soyuz spacecraft set to launch from the Baikonur Cosmodrome in Kazakhstan on Oct. 28. The Soyuz serves as the emergency rescue vehicle of the station and must be replaced about every six months.

Shortly after crew wakeup today, one of the three cooling radiators on the newly installed S1 Truss was deployed serving as a mechanical test for the deployment system. The deployment to its full length of 75 feet began at 3:01 a.m. and was completed nine minutes later. The task was delayed from Sunday for an electrical adjustment. The radiator is not needed operationally until next year.

Peggy Whitson, NASA ISS science officer, and Atlantis' Sandy Magnus will operate the station's robot arm throughout the spacewalk, while Pilot Pam Melroy will again choreograph the Extravehicular Activity (EVA) from Atlantis' flight deck. Wolf will wear the spacesuit with red stripes and Sellers' suit will be all white.

Today's wakeup music for Dave Wolf from his wife Tammy was "You Gave Me The Answer," by Paul McCartney and Wings and came at 2:46 a.m. The station crewmembers awakened about 30 minutes later.

The spacewalk began at 9:11 a.m., and was the 46th devoted to assembly and maintenance of the station. Making quick work of their first task, to remove a bolt preventing activation of a cable cutter on the mobile transporter, Wolf and Sellers moved on to connect ammonia lines and remove structural support clamps that held the truss in place during launch. With Sellers and Wolf working well ahead of schedule, an additional "get ahead" task – installing Spool Positioning Devices on a pump motor assembly – was added to the spacewalk. The pump motor assembly helps to circulate ammonia through the station's cooling system. Throughout today's spacewalk the station's robotic arm, which was used as a work platform by Sellers and Wolf, was operated by NASA's ISS science officer Peggy Whitson and Mission Specialist Sandy Magnus.

Earlier in the day at 6:20 a.m. Commander Jeff Ashby and Pilot Pam Melroy pulsed Atlantis' thrusters for 35 minutes gently raising the altitude of the station by 2.3 miles. The combined results of two reboost maneuvers by Atlantis increased the station's altitude by a total of six miles, setting the stage for the arrival of a replacement Soyuz spacecraft, set for launch on October 28.

Atlantis' crew is scheduled to awaken at 3:46 a.m. Tuesday with the station crew awakening about one-half hour later. Tuesday will see some scheduled off-duty time for the two crews, allowing them some final hours together before Wednesday's scheduled undocking and departure of Atlantis from the station.

Atlantis Commander Jeff Ashby and Expedition Five Science Officer Peggy Whitson put on their air-conditioning maintenance caps, removing and replacing a humidity separator in the station's Quest airlock. That device, which removes excess moisture from the airlock's atmosphere, had been exhibiting some leakage attributed to a clogged filter. The repair work went as planned, and the old unit is destined to come home in the same space on Atlantis that carried up the fresh unit.

Loadmaster Sandy Magnus coordinated the final transfer of equipment and supplies from Atlantis to the station, as well as the packing of items that are being returned to Earth on the shuttle. A total of about 1,800 pounds of supplies were delivered to the station, and an equal amount will be brought back.

The joint crew will be awakened at 2:46 a.m. CDT Wednesday and begin final departure preparations. The two crews will conduct a final farewell ceremony at 5:59 a.m., then gather on the opposite sides of their hatches and close the doors.

Undocking is scheduled for 8:13 a.m. After Pilot Pam Melroy gently eases Atlantis out to a distance of 450 feet, she will fire its reaction control system thrusters and begin a slow fly-around of the station so that her crewmates may take still and video pictures of the station with its newest addition, the Starboard 1 truss structure. Melroy expects to fly at least halfway around the station before separating, but if propellant supplies allow she may be able to make one complete revolution.

Once back on their own, the Expedition Five voyagers – 131 days into their mission, 129 as station crewmembers – return their attention to unpacking a Russian Progress supply vehicle that arrived in late September, and packing up belongings for their own return home scheduled for late November aboard Space Shuttle Endeavour. Endeavour rolled out to its Kennedy Space Center launch pad over the weekend, and the next station addition, a Port 1 truss segment, was loaded in the cargo bay today.

Between now and then, Expedition Five will receive more guests from Earth when a new Russian Soyuz emergency return vehicle and crew arrive following launch Oct. 28 from the Baikonur Cosmodrome in Kazakhstan.

Following undocking, Pilot Pam Melroy flew Atlantis a partial lap around the station, as her crewmates used cameras to document its latest addition and overall condition. At 10 a.m., she fired Atlantis' engines in a final separation maneuver, leaving the Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - to continue stowing away many of the items that were transferred over the past week and preparing for the early November arrival of a new Soyuz return vehicle, and its visiting crew.

Flying solo, the focus on board Atlantis is on preparing for a return trip to Earth on Friday. Commander Jeff Ashby, Melroy and flight engineer Sandy Magnus will check out Atlantis' flight control systems and test fire its reaction control system jets in preparation for re-entry and landing. The entire crew also will begin packing up the cameras, equipment and hardware they've used over the course of the past 10 days in space.

The Atlantis crew will be awakened at 2:16 a.m. to begin what should be its final full day in orbit with landing scheduled for 10:44 a.m. CDT Friday at the Kennedy Space Center in Florida. The Expedition Five crew will awaken at 3:30 a.m., settling into a slightly later than normal shift to support the upcoming visits of the Soyuz taxi crew and Space Shuttle Endeavour.

The first steps in changing Atlantis from a spaceship to an airplane are to test its aero surfaces, required as the orbiter begins to interact with the upper atmosphere on reentry and landing. Also tested today are the thruster jets on the nose and tail of Atlantis which maneuver the vehicle prior to dropping below 400,000 feet in altitude following the deorbit burn.

Atlantis' computers systematically deactivate these jets when desired air pressure readings are detected at various stages throughout entry and landing.

The crew of Commander Jeff Ashby, Pilot Pam Melroy and Mission Specialists Dave Wolf, Sandy Magnus, Piers Sellers and Cosmonaut Fyodor Yurchikhin spend the day stowing equipment, supplies and belongings in preparation for tomorrow's anticipated return to the Kennedy Space Center in Florida.

At 11:46 this morning, the crew will discuss the success of the mission with media representatives from the AP Radio Network, KMOX Radio of St. Louis and WISH-TV of Indianapolis. The interview will air on NASA Television.

Behind the shuttle at a distance of 120 miles (193 kilometers), the ISS Expedition Five crew of Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Cosmonaut Sergei Treschev are preparing for their next visitors, a Soyuz taxi crew scheduled to arrive late this month. The taxi crew will return to Earth in the Soyuz at the station, which is nearing its certified on orbit life limit.

The shuttle crew began its last full day on orbit with a wakeup call from Mission Control at 2:18 a.m. The song "These are the Days" performed by Natalie Merchant was played for Sellers at the request of his wife.

Atlantis' crew sleep begins at about 6:30 this evening and the crew will be awakened at 2:16 a.m. Friday to begin landing preparations.

Commander Jeff Ashby, Pilot Pam Melroy and Flight Engineer Sandy Magnus activated one of three hydraulic power units on Atlantis, tested all of the orbiter's aerosurfaces, and then test-fired the steering jets. All of the systems are in good shape for reentry and landing. The remaining crew members - Dave Wolf, Piers Sellers and Fyodor Yurchikhin - continued packing up gear and hardware in anticipation of tomorrow's landing.

Atlantis has two opportunities to land at the Kennedy Space Center (KSC) on Friday. The first begins with a deorbit burn of the Orbital Maneuvering System engines at 9:36 a.m., followed by a landing at 10:44 a.m. Central (11:44 a.m. Eastern.) In the event weather prevents a landing on that first opportunity, there is a second opportunity, beginning with a deorbit burn at 11:16 a.m. and resulting in a 12:21 p.m. Central (1:21 p.m. Eastern) landing in Florida.

Tomorrow's weather forecast for the shuttle landing facility at KSC is favorable. The backup-landing site at California's Edwards Air Force Base was not called up for support Friday. Atlantis has sufficient consumables to remain in orbit, if necessary, until Tuesday.

Atlantis' crew will begin a scheduled eight-hour sleep period at 6:16 p.m. today, waking just after 2 a.m. Friday to prepare for a homecoming to the Kennedy Space Center. Actual deorbit preparations will get underway at 5:40 a.m. Atlantis' payload bay doors are scheduled to be closed at 6:56 a.m. and the crewmembers will get into their seats at 8:36 a.m.

Meanwhile, aboard the International Space Station, the Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - enjoyed a few hours of off-duty time today. Tomorrow they will turn their attention back to unpacking the Russian Progress resupply vehicle that arrived at the station in late September.

With weather of little concern today, Commander Jeff Ashby piloted the shuttle to its 60th landing at KSC at 10:44 a.m. CDT. The deorbit burn occurred an hour earlier as Atlantis flew high above the southwestern Indian Ocean, dropping the shuttle out of orbit for the high-speed reentry and landing.

Atlantis' ground track carried it above Central America and western Cuba before crossing the west coast of Florida south of Tampa. Ashby took over manual control of Atlantis at an altitude of 50,000 feet, guiding the 200,000 pound shuttle through a 290-degree right turn to line up with Runway 33.

Meanwhile, aboard the International Space Station, the Expedition Five crew was able to watch Atlantis' safe landing while the three crewmembers continue to unpack and stow supplies delivered by the shuttle crew. Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Cosmonaut Sergei Treschev are in their 135th day in space (133rd aboard the station).

Their next visitors are the three members of a Soyuz Taxi Crew scheduled to deliver a fresh rescue spacecraft to the station later this month. Expedition Five's ride home will be aboard Endeavour scheduled to launch no earlier than Nov. 10 bringing another truss segment and the Expedition Six crew.

Atlantis will be hauled into its hangar later today to begin preparations for its next mission to the station in March 2003 on the STS-114 mission.

Atlantis' six crewmembers are expected to hold a news conference at about 4 p.m. today on NASA Television and plan to return to the Johnson Space Center in Houston Saturday at about 5:30 p.m.

Atlantis has two landing opportunities at KSC. The first begins with the firing of the shuttle's braking rockets at 9:36 a.m. and a landing at 10:44 a.m. CDT. A second opportunity for a KSC landing would see the deorbit burn at 11:16 a.m. and a landing at 12:21 p.m. Forecasts call for favorable weather for landing, with scattered clouds, good visibility and 10-knot winds.

The backup-landing site at California's Edwards Air Force Base will not be activated today. Atlantis has enough consumables to stay in orbit until Tuesday.

The crew, Commander Jeff Ashby, Pilot Pam Melroy and Mission Specialists Dave Wolf, Sandy Magnus, Piers Sellers and Cosmonaut Fyodor Yurchikhin, was awakened at 2:25 a.m. by "Someday Soon," performed by Suzy Bogguss. It was for Ashby, requested by his wife.

Deorbit preparations began about 5:40 a.m. The payload bay doors are to be closed at 6:56 a.m.

About 3,000 miles behind the shuttle, the ISS Expedition 5 crew, Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Cosmonaut Sergei Treschev, is in its 135th day in space. Crewmembers are awaiting a taxi crew scheduled to arrive late this month with a replacement for the Soyuz now at the station. Expedition 5 is to return home on the STS-113 mission of Endeavour, scheduled for launch with their Expedition 6 replacements no earlier than Nov. 10.

During the week it was docked to the station, Atlantis did two reboosts of the orbiting laboratory, raising its altitude by about six miles. Another station reboost was performed about 3:25 a.m. today using the engines of the Progress unpiloted cargo carrier docked to the rear of the Zvezda Service Module. It was to raise the station's altitude an additional 6.9 miles and adjust the orbit for the arrival of the new Soyuz. The station's average altitude after the reboost was expected to be 249 miles.

If Atlantis lands on time, crewmembers are tentatively scheduled to return to the Johnson Space Center in Houston Saturday afternoon.

Next week, the taxi crew will bring a new Soyuz to the station and remain on board the ISS for eight days. The Soyuz is scheduled to launch at 9:11 p.m. CST Oct. 29 from the Baikonur Cosmodrome in Kazakhstan. Docking to the station is scheduled for 11 p.m. CST Oct. 31. The taxi crew will undock the Soyuz now at the station and land Nov. 9. The crew, which consists of Russian Commander Sergei Zalyotin, European Space Agency Flight Engineer Frank DeWinne from Belgium and Russian Flight Engineer Yuri Lonchakov, will perform science experiments during their stay on board.

Endeavour is planned to launch from the Kennedy Space Center Nov. 10 between midnight and 4 a.m. EST. Endeavour's STS-113 flight will deliver the next segment of the station's backbone, the (P1) Truss, and the three members of the station's Expedition 6 station crew.

The Expedition 5 crewmembers - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - have already begun packing for their return to Earth aboard Endeavour.

On Thursday, from the robotic workstation in the Destiny lab, Whitson and Korzun successfully "flew" the space station robotic arm through a dry run of the procedure to install the P1 truss. Working in the station's Quest airlock, Whitson prepared the batteries and air regeneration system for the spacesuits that STS-113 spacewalkers Mike Lopez-Alegria and John Herrington will wear when they conduct three spacewalks to help install and activate the P1 truss to the station.

Whitson's own science investigation on board the space station was completed this week with a final data collection. The experiment tests a drug that may prevent the formation of kidney stones during long duration space flights.

Flight controllers at Houston's Mission Control Center Houston sent new files to the three systems computers in the Destiny lab module this week. The computers run life support, thermal control and power systems in the lab. The new files upgraded the operating system in Destiny for the first time since it was mated to the station in February 2001.

Russian "taxi crew" Commander Sergei Zalyotin, European Space Agency Flight Engineer Frank DeWinne from Belgium and Russian Flight Engineer Yuri Lonchakov lifted off in dense fog in the new Soyuz TMA-1 vehicle at 9:11 p.m. Central time (311 GMT Oct. 30). About nine minutes later, the new Soyuz had reached orbit and its solar panels and navigational antennas had deployed.

The new Soyuz is designed to accommodate larger or smaller crewmembers, and is equipped with upgraded computers, a new cockpit control panel and improved avionics. Zalyotin, who commanded the last mission to the Mir Space Station in 2000, DeWinne, a first-time flier, and Lonchakov, who flew on the shuttle Endeavour to deliver the Canadarm2 robotic arm to the ISS in 2001, are scheduled to dock their Soyuz vehicle to the station's Pirs Docking Compartment Thursday night around 11 p.m. CST (500 GMT Nov. 1) for the start of eight days of joint operations. Hatches between the Soyuz and the ISS are scheduled to swing open around 12:40 a.m. CST Friday (640 GMT).

The Expedition 5 crewmembers - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - were asleep at the time of the Soyuz launch. When they are awakened, they will begin their 147th day in space, the 145th day aboard the ISS.

After arriving at the station, Zalyotin, DeWinne and Lonchakov will join their Expedition resident colleagues in performing a variety of scientific experiments, many of them furnished under a commercial contract between the European Space Agency and the Russian Aviation and Space Agency on behalf of DeWinne. The taxi trio is scheduled to board the Soyuz TM-34 return craft that has been linked to the ISS since April, and undock on Nov. 9 for a landing on the steppes of Kazakhstan.

A fresh Soyuz is delivered to the ISS every six months to provide an assured return capability for station residents in the unlikely event a problem would force them to come home prematurely.

Russian "taxi crew" Commander Sergei Zalyotin, European Space Agency Flight Engineer Frank DeWinne from Belgium and Russian Flight Engineer Yuri Lonchakov docked their new Soyuz TMA-1 capsule to the Russian Pirs Docking Compartment of the ISS at 11:01 p.m. Central time last night (501 GMT Nov. 1) as the two craft flew 230 statute miles over central Russia, linking up to the ISS along side an older Soyuz TM-34 return vehicle which has been at the station since April. Zalyotin, DeWinne and Lonchakov will depart the ISS in the older Soyuz on Nov. 9.

A fresh Soyuz is delivered to the ISS every six months to provide an assured return capability for station residents in the unlikely event a problem would force them to come home prematurely. The new Soyuz is designed to accommodate larger or smaller crewmembers, and is equipped with upgraded computers, a new cockpit control panel and improved avionics.

The Expedition 5 crewmembers - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - monitored the arrival of their new visitors from the Zvezda Service Module to which the Pirs docking port is attached.

After conducting leak checks between the Soyuz and the ISS, hatches swung open between the two spacecraft at 12:26 a.m. Central time (626 GMT), enabling the six crewmembers to greet one another and receive congratulatory calls from Russian and European dignitaries gathered at the Russian Mission Control Center in Korolev, outside Moscow.

The visiting "taxi" crew will spend eight days on the ISS. During that time, DeWinne will conduct a host of scientific experiments, some of them in the Microgravity Glovebox housed in the station's Destiny Laboratory.

The arrival of the "taxi" crew sets the stage for the launch of the shuttle Endeavour Nov. 11 to bring a new crew of residents to the ISS to replace Korzun, Whitson and Treschev, who have been in space since June. Endeavour's crew, led by Commander Jim Wetherbee, will also deliver the Port One (P1) truss segment to the ISS, the fourth of 11 such trusses which form the backbone for the ISS for the addition of new modules and power-producing solar arrays.

-MOREDetails about the final days of the work on orbit by the Expedition Five crew and the progress of the Soyuz "taxi" flight to the station will be offered in an ISS Mission Status Briefing to be held at the Johnson Space Center, TX on Tuesday, Nov. 5, at 1 p.m. CST.

The week started out with Expedition 5 Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev making sure station systems are ready to support installation of the next piece of the orbiting outpost's truss structure. They performed a final checkout of the Mobile Transporter, Canadarm2, the Quest airlock, and the spacewalk tools and equipment that already are on board. After those activities were complete, they began pre-packing items that will come home with them aboard Endeavour, which is set to launch with a replacement crew between 11 p.m. Sunday and 3 a.m. Monday CST.

Once the Port One (P1)1 truss is installed, the Expedition 5 crew will hand over control of the station to Expedition 6 Commander Ken Bowersox and Flight Engineers Nikolai Budarin and Don Pettit and return home with Endeavour's crew - Commander Jim Wetherbee, Pilot Paul Lockhart and Mission Specialists Mike Lopez-Alegria and John Herrington.

The visiting taxi crew - Commander Sergei Zalyotin, European Space Agency Flight Engineer Frank DeWinne from Belgium and Russian Flight Engineer Yuri Lonchakov - will undock from the station at 2:41 p.m. CST on Saturday. Zalyotin will fire the Soyuz deorbit engines at 5:10 p.m., bringing his crew in for a landing on the Kazakh steppes at 6:04 p.m.

The taxi crew, which rode into orbit aboard an upgraded Soyuz TMA capsule with more legroom and more modern cockpit controls, displays and computers, will ride home in the older Soyuz TM-34 return vehicle that has been at the station since April. A fresh Soyuz is delivered to the ISS every six months to provide an assured return capability for station residents in the unlikely event they would need to come home early.

During their eight-day stay on the station, the taxi crew conducted a host of medical, protein crystal growth and materials processing experiments. With DeWinne leading the investigations, the crew looked at human physiology in microgravity and how crystals grow and alloys form inside the Microgravity Science Glovebox in the Destiny Laboratory module.

Flight controllers in Houston are troubleshooting with the Carbon Dioxide Removal Assembly in the Destiny lab. CDRA is a system of absorption beds, tubing and valves that remove excess carbon dioxide from the atmosphere after it is expelled during breathing and vents it overboard. Two of six valves appear to be malfunctioning, causing the system to shut down several hours after it is started. The system supplements the station's Russian Vozdukh carbon dioxide removal system when more than three crewmembers are on board.

Troubleshooters have confirmed that a recent lab systems software update is not the cause of the problems, and they are refining their activation procedures to try to support the upcoming shuttle and Expedition 6 crews with CDRA using additional ground commanding. Lithium hydroxide canisters, which absorb carbon dioxide through a chemical process, may also be used to supplement the primary system; one canister was used during some of the CDRA troubleshooting activities.

The Elektron unit that generates oxygen by separating the oxygen and hydrogen atoms from water molecules also is not working properly. Korzun and Treschev conducted troubleshooting activities this week and are scheduled to replace the unit's liquid electrolysis module on Sunday. Additional oxygen is available in the Progress vehicle docked to the aft end of Zvezda. Oxygen and nitrogen also are available in tanks attached to the Quest airlock. Oxygen also is available from Russian oxygen generating "candles."

Saturday's departure of the taxi crew will set the stage for the launch of the shuttle Endeavour. The crew arrived at the Kennedy Space Center last night, and the launch countdown began today. Endeavour will take the 1 truss structure and additional resupply items, as well as two replacement valves for the station's CDRA system to the ISS. The three-pound aluminum replacement valves are about 5 by 9 by 6 inches, and look like valves in a home air conditioning system.

Russian "taxi crew" Commander Sergei Zalyotin, European Space Agency Flight Engineer Frank DeWinne from Belgium and Russian Flight Engineer Yuri Lonchakov undocked the Soyuz TM-34 capsule from the Zarya Control Module's nadir docking port at 2:44 p.m. Central time (2044 GMT) and backed away from the ISS to a safe distance through a series of thruster firings. The Soyuz TM-34 vehicle arrived at the ISS in April. Left behind docked to the Russian Pirs Docking Compartment of the ISS is the new Soyuz TMA-1 return craft which carried Zalyotin, DeWinne and Lonchakov from the Baikonur Cosmodrome in Kazakhstan during their launch on Oct. 30. They arrived at the ISS on Nov. 1.

A fresh Soyuz is delivered to the ISS every six months to provide an assured return capability for station residents in the unlikely event a problem would force them to come home prematurely. The new Soyuz is designed to accommodate larger or smaller crewmembers, and is equipped with upgraded computers, a new cockpit control panel and improved avionics.

The Expedition 5 crewmembers - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - bid the "taxi" crew farewell earlier today before closing hatches between the station and the Soyuz return vehicle.

Later today, Zalyotin will perform a deorbit maneuver using the Soyuz thrusters to begin the descent back home for a landing on the steppes of Kazakhstan at 6:04 p.m. Central time (0004 GMT Nov. 10, 5:04 a.m. Kazakhstan time Nov. 10).

The departure of the "taxi" crew sets the stage for the launch of the shuttle Endeavour on the STS-113 mission early Monday to bring a new crew of residents to the ISS to replace Korzun, Whitson and Treschev, who have been in space since June. Endeavour's crew, led by Commander Jim Wetherbee, will also deliver the Port One (P1) truss segment to the ISS, the fourth of 11 such trusses that will form the backbone for the ISS for the addition of new modules and power-producing solar arrays.

During the week, Expedition 5 packed, checked and labeled experiment racks, and did a dry run of the installation of the Port One (P1) truss segment onto the ISS using the Canadarm2. The crew also performed maintenance on the VOA (volatile organics analyzer), which looks for volatile organic compounds in the station's atmosphere, and replaced a cable on the station's treadmill. They also set up the EarthKam equipment to give over 2,000 students and teachers across the U.S. and Japan a chance to take pictures of the Earth using a remotely controlled camera aboard the station. Whitson deactivated the camera Friday, but Expedition 6 will reactivate it for use during its mission.

The space shuttle Endeavour will deliver the Expedition 6 crew, along with the P1 truss, to the station during the STS-113 mission. The P1 will be the third segment of the station's integrated truss system to be launched this year. Part of the station's backbone, it is one of 11 such truss segments that will support cooling radiators power-producing solar arrays and a railroad on which the Canadarm2 can move.

Preparations continue for the launch next week of Endeavour to the ISS next week.

On board the International Space Station, the current residents - Expedition Five Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - were told of Endeavour's on-time liftoff by spacecraft communicator Stan Love in the space station control center.

"Thanks so much for the play-by-play Stan. That was great," Whitson said in response to the news that the Expedition Six crew - Commander Ken Bowersox and Flight Engineers Nikolai Budarin and Don Pettit - were en route.

Once on orbit, Commander Jim Wetherbee, Pilot Paul Lockhart and Mission Specialists Mike Lopez-Alegria and John Herrington, along with Bowersox, Budarin and Pettit will begin setting up equipment on board and preparing to open the shuttle's payload bay doors to begin orbital operations.

Endeavour is scheduled to dock to the station about 3:30 p.m. central time Monday, setting the stage for Tuesday's installation of the Port One (P1) truss to the International Space Station. As was the case during Atlantis' flight last month to deliver the Starboard One truss segment, three spacewalks will be conducted by Lopez-Alegria and Herrington to help activate the new truss' systems. P1 is the third truss segment to be launched this year. It is one of 11 truss segments that will form the structural backbone for the station and provide the cooling and support for new solar arrays to be delivered to the station next year.

Endeavour's crew will go to sleep just before 1 a.m. Sunday and will be awakened just before 9 a.m. to begin its first full day in orbit. The crew will begin check-outs of the Shuttle's robot arm, the spacesuits to be worn by Lopez-Alegria and Herrington during their spacewalks and the tools and mechanisms involved in Monday's rendezvous with the ISS.

In preparation for Monday's docking, Endeavour's crew - Commander Jim Wetherbee, Pilot Paul Lockhart, Mission Specialists Mike Lopez-Alegria and John Herrington, and the Expedition Six crew Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and flight engineer Nikolai Budarin - verified operation of the equipment used to support a smooth rendezvous and soft docking. A camera was installed to give Wetherbee a view of the station's docking port through the shuttle's docking system, a shock-absorbing ring that will make the first contact was extended and a variety of handheld cameras and distance-measuring devices were checked out. In addition, Lopez-Alegria and Herrington inspected and checked out the spacesuits being delivered to the station for use on three spacewalks to install and outfit the P1 truss segment.

Checkout of the shuttle's Remote Manipulator System went smoothly today, but the robotic arm camera survey of Endeavour's payload bay ran a little longer than expected. The robotic arm's wrist roll joint was commanded in extra maneuvers to help work in lubrication that was applied during the arm's preflight servicing. The robotic arm is ready to support operations to remove Endeavour's primary cargo, the P1 or port truss, from the payload bay on Tuesday.

Also today, Bowersox, Budarin and Pettit spoke with reporters from USA Today and AP Radio News. The trio will become the sixth resident crew to live and work in space aboard the International Space Station, replacing the current Expedition Five residents.

Onboard the station, the Expedition Five crew, Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev, continued preparations for the arrival of Endeavour, and their replacement crew.

Endeavour's crew is scheduled to go to sleep about 11:20 p.m. Central time and awaken about 7:20 a.m. Monday.

Onboard the station, the Expedition Five crew, Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev, awakened at 7:45 a.m. to continue preparations for the arrival of Endeavour, and their replacement crew.

In preparation for Monday's docking, Endeavour's crew - Commander Jim Wetherbee, Pilot Paul Lockhart, Mission Specialists Mike Lopez-Alegria and John Herrington, and the Expedition Six crew Commander Ken Bowersox, NASA ISS science officer Don Pettit and flight engineer Nikolai Budarin - will verify operation of the equipment used during docking. The centerline camera will be installed in the docking system, the orbiter docking system ring will be extended and a variety of handheld cameras and distance-measuring devices will be checked out. In addition, Lopez-Alegria and Herrington will inspect and checkout the spacesuits they will wear during three scheduled spacewalks to install and outfit the P1 truss segment.

Monday's docking to the International Space Station is scheduled to occur about 3:26 p.m. central time and sets the stage for those three spacewalks to be conducted over a period of five days. The P1 truss is the third such segment to be launched this year, one of 11 truss segments that will form the structural backbone of the station. The trusses will also provide cooling and support for new solar arrays, which will be delivered to the station next year.

At 6:55 p.m., Bowersox, Budarin and Pettit will talk with reporters from USA Today and AP Radio News. The trio will become the sixth resident crew to live and work in space aboard the International Space Station, replacing the current Expedition Five residents who are beginning their 173rd day in space today.

The rendezvous and docking of Endeavour with shuttle Commander Jim Wetherbee at the controls went smoothly. Docking occurred about 248 statute miles above the South Pacific off the southeastern coast of Australia.

After successful leak checks, the last hatch between the two spacecraft was opened at 5:31 p.m. The Expedition 5 crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - welcomed the new arrivals to the orbiting laboratory to begin a week of docked operations. After greetings, the first item on the agenda was a safety briefing by Korzun.

Expedition 6 Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin later installed their custom seatliners in the Soyuz spacecraft that could serve as a return vehicle in the unlikely event it became necessary to leave the station unexpectedly. Their call saying they had completed the installation and pressure checks of the Russian SOKOL re-entry suits made them station crewmembers. It also officially ended the Expedition 5 increment, after 171 days, 3 hours and 33 minutes.

Expedition 5 was launched last June 5 and has been on the station since June 7. The trio will return to Earth with the Endeavour crew, Wetherbee, Pilot Paul Lockhart, Mission Specialists Michael Lopez-Alegria and John Herrington.

During the week together at the station, Expedition 5 crewmembers will conduct extensive briefings for their successors, familiarizing them with their new home and the location and function of its equipment and experiments. They also will brief the Expedition 6 crew on the inventory and location of supplies aboard the station.

On Tuesday the shuttle and station crews will lift the new P1 truss segment from Endeavour's cargo bay with the shuttle's robotic arm, operated by Wetherbee. He will hand the P1 off to the Canadarm2, the station's arm, which Bowersox and Whitson will use to position it for installation.

Once remotely operated bolts have secured P1 to the S0 truss center, Lopez-Alegria and Herrington will begin the first of three spacewalks to make electrical, fluid and data connections between it and the rest of the station and to outfit the new truss segment.

Subsequent spacewalks will be made Thursday and Saturday. Each of the three spacewalks will be about 61/2 hours long.

Onboard the space station, the Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - awakened at 7:50 a.m. to continue preparations for the arrival of their latest guests, including their replacement crew.

After hatch opening and a safety briefing conducted by Korzun, the two crews will begin transferring supplies and equipment that will be needed during the three upcoming spacewalks, as well as the Expedition Six seat liners and reentry suits for the Soyuz spacecraft. The Soyuz serves as a lifeboat for the station, enabling a crew to come home quickly in the event of an emergency. Each crewmember has their own custom-fitted seat liner to cushion the effects of a Soyuz landing. The official exchange of resident crews aboard the station will be complete once the Expedition Six crew has transferred its seatliners to the Soyuz spacecraft and the Expedition Five crew transfers its seatliners over to Endeavour for the return trip home.

Over the next seven days, the astronauts and cosmonauts will work together to attach another truss to the space station, the Port 1 (P1) truss, and complete the changeover between the Expedition Five and Six crews. The first of three spacewalks to install and outfit the truss is scheduled for Tuesday afternoon, to be conducted by Mission Specialists Mike Lopez-Alegria and John Herrington.

Endeavour's crew - Commander Jim Wetherbee, Pilot Paul Lockhart, Mission Specialists Lopez-Alegria and Herrington, and the Expedition Six crew Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin - will begin rendezvous operations around 10:35 a.m. The final approach phase of the docking is scheduled to begin about 1 p.m. with hatch opening between the two spacecraft scheduled to occur at 4:45 p.m.

Beginning around 9:20 a.m., Endeavour Commander Jim Wetherbee will use the shuttle's robotic arm to lift the P1 truss from the cargo bay, then hand it off to the station's robotic arm. Expedition Six Commander Ken Bowersox and Expedition Five NASA ISS Science Officer Peggy Whitson will fly the station's robotic arm. Bowersox and Whitson will position the P1 for installation around 1 p.m.

About 2:20 p.m., after remotely-operated bolts have secured the P1 truss to the station's central Starboard Zero (S0) truss segment. Mission Specialists Michael Lopez-Alegria and John Herrington will exit the station's Quest airlock to begin the first of the mission's three spacewalks. Lopez-Alegria will start by making connections between the P1 and the S0 while Herrington releases launch restraints on the Crew and Equipment Translation Aid cart. Lopez-Alegria also will install Spool Positioning Devices onto the station. Both spacewalkers will then remove a drag link on the P1 that served as a launch restraint.

The final major task of the 61/2-hour spacewalk is the installation by both spacewalkers of a Wireless video system External Transceiver Assembly (WETA) onto the Unity module. The WETA will be used to support helmet camera communications from future spacewalkers.

Endeavour Pilot Paul Lockhart will coordinate the spacewalk from the flight deck of the shuttle. During the spacewalk, the Expedition Five crew - Commander Valery Korzun, Whitson and Flight Engineer Sergei Treschev - will continue handover discussions with the Expedition Six crew - Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin.

P1 was removed from Endeavour's payload bay at 9:22 a.m. CST by the shuttle's robotic arm, operated by Commander Jim Wetherbee. He handed it off to the station's Canadarm2, operated by Expedition 6 commander Ken Bowersox and Expedition 5 NASA ISS Science Officer Peggy Whitson, and released the shuttle arm's grip on P1 a little before 11 a.m. Whitson and Bowersox maneuvered the 14-ton, 45-foot truss segment to its installation position.

P1 is the third segment of the Integrated Truss Structure to be installed this year. A fourth segment, the P6 truss, supports the 240-foot-long solar arrays atop the station. It was installed there in December 2000 and will be moved later to the left end of the station's backbone. At completion, the integrated truss will consist of 11 segments stretching the length of a football field.

The spacewalk began at 1:49 p.m., about 30 minutes earlier than planned, after the four bolts securing the P1 to the S0 truss centerpiece had been driven home by remote commands. The spacewalk ended a little before 8:35 p.m. for a total time of 6 hours and 45 minutes.

Herrington and Lopez-Alegria hooked up electrical connections between P1 and the station, installed spool positioning devices designed to ensure that quick disconnect devices in fluid lines will function properly, and released launch locks securing the Crew and Equipment Translation Aid (CETA) cart, a kind of hand car for the truss railway. The two spacewalkers also removed two drag links, large metal rods that had supported P1 during launch, and stowed them in the P1 framework. Finally, after Herrington had topped off his oxygen supply in the airlock, they installed Node Wireless video system External Transceiver Assembly (WETA) antennas allowing reception from spacewalkers' helmet cameras without a shuttle present.

Endeavour Pilot Paul Lockhart, with help from Bowersox and Expedition 6 Science Officer Don Pettit, served as intravehicular officer during the spacewalk, coaching Lopez-Alegria and Herrington through their tasks and keeping them on the timeline.

The spacewalk was the 22nd station-based spacewalk, and brought the total time for space station spacewalks to 292 hours, 10 minutes. There have been 25 shuttle-based assembly spacewalks.

Lopez-Alegria, wearing the spacesuit with red stripes, and Herrington, in the all-white spacesuit, will conduct two more spacewalks, each scheduled for 61/2 hours, on Thursday and Saturday. Both will focus on making additional connections between the new truss segment and the station, and outfitting the P1.

Expedition 5 Commander Valery Korzun, Whitson and Flight Engineer Sergei Treschev conducted handover discussions with their Expedition 6 successors, Bowersox, Pettit and Flight Engineer Nikolai Budarin, during parts of the Tuesday spacewalk.

In the afternoon, Endeavour's crew - Commander Jim Wetherbee, Pilot Paul Lockhart and Mission Specialists Michael Lopez-Alegria and John Herrington - will take time to prepare for the second spacewalk of the mission, scheduled for Thanksgiving Day. The second spacewalk will focus on making additional connections between the new Port 1 (P1) truss segment and the station and outfitting the P1 for future use.

The Expedition Five and Six crews also will continue handover discussions and training as Expedition Six - Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin - begins their stay. Expedition Five - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev -- is completing six months in orbit as they prepare to return home.

Wetherbee, Lockhart, Lopez-Alegria and Herrington will take a break from their moving duties at about 2:30 p.m. CST for interviews with KFOR-TV of Oklahoma City, OK; the Chickasaw Times newspaper; and the Cedena Ser radio network.

This morning, Mission Control radioed up birthday greetings to Wetherbee, who is celebrating his 50th birthday in orbit today.

The crew of Endeavour was awakened at 7:20 a.m. and the Expedition Six crew was awakened at 7:50 a.m. The shuttle and station remain in excellent condition.

The transfer of items between the two spacecraft is going smoothly, as are the handover briefings for Expedition 6 Commander Ken Bowersox, Cosmonaut Nikolai Budarin and NASA ISS Science Officer Don Pettit. Expedition 5 Commander Valery Korzun, NASA Science Officer Peggy Whitson and Flight Engineer Sergei Treschev are familiarizing the new arrivals with station systems and procedure, and discussing the location of equipment and supplies on the ISS.

This afternoon, Whitson and Bowersox replaced two valves and cleared debris from vent lines of the Carbon Dioxide Removal Assembly (CDRA) in the station's U.S. Destiny laboratory. The job was completed about 8 p.m. CST. Later Mission Control radioed them that the valve replacement had been successful, but that there was a leak in one of the CDRA vacuum lines. Whitson and Bowersox began efforts to find and fix that leak late today. CDRA had not been working well for the past several weeks. A Russian system cleanses the station atmosphere of the carbon dioxide exhaled by the normal three-person crew, but CDRA is needed to handle the load of larger crews.

NBC's Jay Leno wished Endeavour Commander Jim Wetherbee a happy 50th birthday. The good wishes were videotaped during Leno's show and transmitted to Endeavour via Houston's Mission Control Center.

This afternoon Wetherbee, Endeavour Pilot Paul Lockhart, Lopez-Alegria and Herrington talked with reporters from KFOR-TV of Oklahoma City, Okla., the Chickasaw Times newspaper; and the Cadena Ser radio network of Spain. The radio network spoke with Lopez-Alegria in Spanish.

Endeavour performed the first of three scheduled reboosts of the station a little after 11 a.m., increasing the altitude of the orbiting laboratory by about 2.8 statute miles. That left the average altitude of the station and Endeavour at almost 244 statute miles. Subsequent reboosts are scheduled for Friday and Sunday.

Thursday's second of three STS-113 spacewalks will see Lopez-Alegria and Herrington make more electrical, data and fluid line connections for the new Port One (P1) truss segment, install a second wireless video antenna system and move a Crew Equipment Translation Aid railway handcar from the P1 to the S1 truss. P1 was installed just before the Tuesday spacewalk. Thursday's and Saturday's spacewalks each will last about 61/2 hours.

Thanksgiving travel is being taken to new heights by Endeavour and ISS crewmembers. They will log about 1.68 million miles during the four-day weekend, with no weather or traffic delays, no airport security problems and certainly no crowds. Their vehicles' mileage over just those four days is excellent -- almost unlimited. Lopez-Alegria and Herrington are scheduled to travel about 227,500 Thanksgiving weekend miles outside the ISS-Endeavour complex during their two spacewalks.

The Thanksgiving Day spacewalk started at 12:36 p.m. CST, almost 45 minutes ahead of schedule, and ended officially at 6:46 p.m.

Lopez-Alegria and Herrington were helped by intravehicular officer Paul Lockhart, Endeavour's pilot, who coached them through their activities from the shuttle's aft flight deck. Expedition 5 NASA ISS Science Officer Peggy Whitson, with help from her Expedition 6 successor Don Pettit, operated the station's Canadarm 2. Endeavour Commander Jim Wetherbee did photo and TV documentation.

The first task for Lopez-Alegria, wearing the spacesuit with red stripes, and Herrington, in the all-white spacesuit, was connection of two fluid jumpers between P1 and the Starboard Zero (S0) truss centerpiece. The jumpers link plumbing for ammonia in the station's cooling system. Next the spacewalkers removed the starboard keel pin, a launch support, and using the Crew and Equipment Translation Aid - one of two handcar-like devices on the truss railway - moved it to the proper location and stowed it in the P1 truss structure.

Lopez-Alegria and Herrington installed a second Wireless video system External Transceiver Assembly (WETA), this one on the P1 truss. They had installed the first WETA on the station's Unity Node during their Tuesday spacewalk. After removal and stowage of the port keel pin, they did the first of the additional jobs, releasing launch locks on the P1's radiator beams. Then they turned their attention to relocation of the CETA cart.

Herrington, in a foot restraint on Canadarm2, lifted the cart from its tracks and held it while Whitson swung him and his cargo around the front of the station, past Endeavour's cargo bay and to the Starboard One (S1), where he attached the cart to tracks and secured it to its sister CETA, launched with the S1 truss on Atlantis' STS-112 flight in October. The relocation was done to clear the P1 tracks for the Canadarm2 to move along them on its Mobile Transporter and Mobile Base System.

The CETA move accomplished, the two spacewalkers moved on to the second additional task, reconnection of one of the cables on the WETA installed Tuesday. Both extra jobs took about 20 minutes.

The oxygen prebreathe protocol before today's spacewak to purge nitrogen from spacewalkers' bloodstreams, was done on the shuttle's cycle ergometer. Whitson and Expedition 6 Commander Ken Bowersox checked out the station's cycle ergometer with a newly uplinked procedure to use it in manual mode.

Expedition 5 Commander Valery Korzun, Whitson and Flight Engineer Sergei Treschev continued their handover briefings for Bowersox, cosmonaut Nikolai Budarin and Pettit. Transfer of equipment and supplies between the station and shuttle also continued.

The Carbon Dioxide Removal Assembly (CDRA) is functioning well. Whitson and Bowersox replaced two valves and cleaned airlines on the device on Wednesday, and later that evening they repaired a leak in a CDRA vacuum line.

Endeavour Mission Specialists Mike Lopez-Alegria and John Herrington will exit the station's Quest airlock for a second time during this mission to begin a 61/2-hour spacewalk. Scheduled to begin about 1:20 p.m. central time, the work outside the station today will see Lopez-Alegria and Herrington connect fluid lines from the new Port One (P1) truss segment to the Starboard Zero (S0) truss; install a second wireless video antenna system to the P1; relocate stanchions that were used to hold the P1 in place during launch; and move a Crew Equipment Translation Aid railway handcar from the P1 to the Starboard One (S1) truss.

Endeavour Pilot Paul Lockhart will coordinate the spacewalk from the orbiter's flight deck and Endeavour Commander Jim Wetherbee will provide photo and TV support. From the ISS, Expedition Five NASA Science Officer Peggy Whitson will provide robotic arm support using the station's Canadarm2, and will be assisted by Expedition Six NASA ISS Science Officer Don Pettit.

Expedition Five Commander Valery Korzun, Whitson and Flight Engineer Sergei Treschev will also continue their handover and training briefings for Expedition Six Commander Ken Bowersox, Flight Engineer Nikolai Budarin and Pettit.

Whitson and Bowersox will take some time today to test the station's bicycle ergometer, which experienced some trouble over the weekend. In addition to being used for exercise, it is used as part of a pre-spacewalk protocol to purge nitrogen from crewmembers' bodies. Testing of the Carbon Dioxide Removal Assembly in the station's Destiny laboratory continued overnight and showed that maintenance work performed by the crew on Wednesday had resolved a faulty valve problem with the system.

Handover briefings of the Expedition 6 crew, Commander Ken Bowersox, cosmonaut Nikolai Budarin and NASA ISS Science Officer Don Pettit, by their Expedition 5 predecessors, Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and cosmonaut Sergei Treschev, continued. The briefings focus on procedures aboard the ISS, science and the location of equipment and supplies.

This afternoon Korzun ceremonially handed over the reigns of the station to Bowersox. Expedition 6 has been the official station crew since Monday when they installed their custom seat liners in the Soyuz spacecraft attached to the station. Later in the afternoon the 10 astronauts and cosmonauts held their crew news conference, fielding questions from reporters at Johnson Space Center and Kennedy Space Center.

Endeavour commander Jim Wetherbee initiated a series of shuttle thruster firings which boosted the altitude of the International Space Station by about eight-tenths of a mile this morning. The reboost left the station at an average altitude of more than 244 statute miles. It was the second of three reboosts during Endeavour's mission to the station. The first, on Wednesday, increased the station's altitude by about 2.8 miles. A third reboost is scheduled for Sunday.

Whitson and Pettit did troubleshooting on the Microgravity Science Glovebox (MSG) on board the station. They checked electrical circuits upstream and downstream of the MSG's power distribution and conversion box - the device that provides electrical power to the facility - in hopes of identifying what caused the component to fail Nov. 20.

Endeavour astronauts Michael Lopez-Alegria and John Herrington reviewed procedures for their third and final spacewalk of the STS-113 mission on Saturday. Participating were pilot and spacewalk intravehicular officer Paul Lockhart, Bowersox and Canadarm2 operators Whitson and Pettit. Much of the spacewalk will be devoted to installation of 33 spool positioning devices, to ensure that quick disconnect devices in station ammonia coolant lines will release as designed. Other tasks include connecting Ammonia Tank Assembly umbilicals and reconfiguring a circuit breaker on the Main Bus Switching Unit. If time allows, they also will reconfigure the Squib Firing Unit, designed to release Port One truss radiator panels for deployment.

Among the items to be transferred today are various science experiments, two returning home aboard Endeavour and one moving to the station. This morning, Mission Specialist Mike Lopez-Alegria and Expedition Five NASA ISS Science Officer Peggy Whitson will transfer the Protein Crystal Growth Single Thermal Enclosure System (PCG-STES) - Unit 7 to Endeavour, while Expedition Six Commander Ken Bowersox will transfer PCG-STES Unit 10 from the shuttle to the station. This afternoon, Lopez-Alegria and Expedition Six NASA ISS Science Officer Don Pettit will transfer the Plant Generic Bioprocessing Apparatus (PGBA) to Endeavour. Plants grown while on orbit will be studied by researchers on the ground.

Whitson and Pettit will also spend some time today troubleshooting the Microgravity Science Glovebox (MSG) on board the station. The MSG recently developed a problem with its power distribution and conversion box - the device that provides electrical power to the facility.

To date, NASA has conducted more than 90,000 hours of scientific research aboard the station and the Expedition Six crew is scheduled to conduct 18 new or continuing experiments.

About 11 a.m., Commander Jim Wetherbee will fire Endeavour's small thruster jets to gently raise the altitude of the station by slightly less than one mile. Late today, Pilot Paul Lockhart, Mission Specialist John Herrington, Lopez-Alegria, Whitson, Bowersox and Pettit will take time to review plans for Saturday's third and final scheduled spacewalk of the mission.

A formal Change of Command ceremony between the Expedition Five and Six crews is scheduled for 2:20 p.m., but may occur earlier. The full crews also will gather for a joint crew news conference beginning at 3:49 p.m. central time.

Pilot Paul Lockhart will coordinate the spacewalk from the aft flight deck of Endeavour. The station's robotic arm, the Canadarm2, will be operated at varying times by Expedition Five Flight Engineer Peggy Whitson, Expedition Six Commander Ken Bowersox and Expedition Six NASA ISS Science Officer Don Pettit. Commander Jim Wetherbee will provide TV and photo support.

The spacewalkers will begin by installing 33 spool positioning devices on various locations around the outside of the station. The clamp-like devices ensure that the quick disconnect fittings in the station's ammonia coolant lines release as designed.

Other spacewalk tasks include connecting the Ammonia Tank Assembly umbilicals and reconfiguring a circuit breaker on the Main Bus Switching Unit. If time allows, the two also will reconfigure the Squib Firing Unit, a pyrotechnic device designed to release the Port One truss radiator panels when they are deployed next year.

Before the spacewalk begins, Whitson and Bowersox will command the Canadarm2 to walk off its current location on the Destiny Laboratory to its mobile base on the P1 truss. Whitson will operate the robotic arm with Pettit assisting during some of the spacewalk activities. When Herrington is finished, Whitson and Bowersox will command the Canadarm2 to return to a Power and Data Grapple Fixture on the Destiny Laboratory.

During the spacewalk, Expedition Five Commander Valery Korzun and Flight Engineer Sergei Treschev will continue handover activities with Bowersox and Expedition Six Flight Engineer Nikolai Budarin. Korzun and Treschev also will complete their final sessions in the Lower Body Negative Pressure suit, a Russian device to help the cosmonauts prepare for their return to Earth's gravity.

This morning Endeavour Commander Jim Wetherbee initiated a series of firings of Endeavour's thrusters to raise the station's altitude by about 2.8 statute miles. This was the third reboost of the flight and left the ISS almost 61/2 miles higher than it was when the shuttle docked on Nov. 25. The station's average altitude is now about 247 miles.

Shuttle crewmembers, Wetherbee, Pilot Paul Lockhart, Mission Specialists Michael Lopez-Alegria and John Herrington, and Expedition 5's NASA ISS Science Officer Peggy Whitson, her Expedition 6 successor Don Pettit and Expedition 6 Commander Ken Bowersox, spoke with representatives of Indian Country Today and Native America Calling radio network.

Transfer activities wound down, with the crew wrapping up movement of supplies, equipment and experiments between the two spacecraft. Endeavour brought more than 2,500 pounds of material to the station in the shuttle's crew compartment.

During the afternoon, Pettit and Whitson did additional troubleshooting on the Microgravity Science Glovebox (MSG) in the station's U.S. laboratory Destiny. The glovebox allows experiments with fluids, flame, particles or fumes to be performed in an enclosed environment. The MSG's power distribution and conversion box failed Nov. 20. The box will be returned to Earth aboard Endeavour, leaving the MSG inactive.

Handover talks continued between the Expedition 5 crew, Commander Valery Korzun, Whitson and cosmonaut Sergei Treschev, and Expedition 6 crewmembers Bowersox, Cosmonaut Nikolai Budarin and Pettit.

Hatches between the two spacecraft are to be closed about 11:15 a.m. CST Monday, with Endeavour undocking from the station about 2:05 p.m. near the west coast of Australia after a pass over the Indian Ocean. Landing is scheduled for Wednesday afternoon at Kennedy Space Center.

After final farewells among the STS-113 and Expedition 5 and 6 crews, the hatches between the spacecraft were closed at 11:57 a.m. CST. Following a series of pressure and leak checks, Endeavour gently undocked from the station at 2:05 p.m. as the two spacecraft flew over northwestern Australia. Total docked time for the mission was six days, 22 hours and six minutes.

As Endeavour departed the station, Bowersox rang the ship's bell on board and wished the crew a safe landing. Endeavour Commander Jim Wetherbee wished the Expedition 6 crew "fair winds." After a one-quarter-lap fly-around of the station, Pilot Paul Lockhart fired a final separation burn of Endeavour's engines at 3:01 p.m. and began its final departure from the station.

All major mission objectives were accomplished during Endeavour's stay at the ISS. The 14-ton Port One truss segment, one of 11 such structures that will form the station's backbone, was delivered and installed over the course of three spacewalks by Mission Specialists Michael Lopez-Alegria and John Herrington, and the station crews were exchanged. With its latest addition, the station's mass stands at 197 tons, or about 400,000 pounds. Returning home after spending 178 days on the station is the Expedition 5 crew -- Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev.

At 4:05 p.m., Endeavour's crew released two miniature satellites as part of an experiment referred to as MEPSI. Funded by the Defense Advanced Research Projects Agency (DARPA), the two small satellites, which are tethered together, were released from Endeavour's payload bay to fly free for three days as a technology demonstration of the launcher assembly and use of micro- and nano-technologies in space systems.

The focus of activities aboard Endeavour on Tuesday will include a checkout of the systems that will be used during Wednesday's planned landing at the Kennedy Space Center. Endeavour is scheduled to land at 2:48 p.m., bringing Korzun, Whitson and Treschev home after 182 days in space. Weather for landing is forecasted to be questionable.

Endeavour will leave behind the Expedition Six Crew - Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin - who are scheduled to live and work aboard the station for the next four months.

Endeavour Commander Jim Wetherbee, Pilot Paul Lockhart, Mission Specialists Michael Lopez-Alegria and John Herrington, and Expedition Five Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev are scheduled to begin those farewells at 11:15 a.m.

Endeavour is scheduled to undock from the space station at 2:05 p.m., after bringing the station a new resident crew, installing the Port One truss and transferring more than 2,500 pounds of supplies, equipment and experiments. As Endeavour gently undocks and backs slowly away from the station, the two vehicles should be flying high over Western Australia.

Shortly after undocking, the Endeavour crew will release two miniature satellites as part of an experiment referred to as MEPSI. Funded by the Defense Advanced Research Projects Agency (DARPA), the two small satellites, which are tethered together, will be released from Endeavour's payload bay to fly free for three days as a technology demonstration of the launcher assembly and use of micro-and nano-technolgoies in space systems.

As the Expedition Six crew settles into its first day alone aboard the station, Endeavour's crew will begin stowing away equipment and hardware in anticipation of Wednesday's scheduled landing at the Kennedy Space Center. Weather permitting, Endeavour is scheduled to return to Earth on Wednesday at 2:48 p.m. central.

The crew will spend its day stowing away equipment and hardware, and preparing their vehicle for its high-speed reentry. With a landing tomorrow, the returning Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev -will have spent 182 days in space. Approximately 2,203 pounds of equipment and experiments from the International Space Station will also return home aboard Endeavour.

Over the course of an 11-day mission, the STS-113 crew - Commander Jim Wetherbee, Pilot Paul Lockhart and Mission Specialists Mike Lopez-Alegria and John Herrington - Whitson, Korzun and Treschev, and the Expedition Six crew of Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin, combined to install the new P1 truss to the station, perform three spacewalks to outfit and activate the truss, and transfer supplies and equipment between the two spacecraft.

Preliminary weather forecasts for tomorrow's landing in Florida indicate the possibility of clouds and rain showers in the vicinity of the landing site. Flight controllers will continue to watch weather conditions and receive updated briefings throughout the day today.

About 2 p.m. today, Endeavour's crew will take time to discuss the successful mission with CBS "Up to the Minute," TV-E Spain and Tulsa World newspaper. Aboard the space station, Bowersox, Pettit and Budarin are spending their 10th day in space unpacking the 2,135 pounds of supplies and equipment brought to the station by Endeavour.

Commander Jim Wetherbee, Pilot Paul Lockhart and Flight Engineer John Herrington activated one of three hydraulic power units on Endeavour, tested all of its aerosurfaces, and then test-fired Endeavour's steering jets. The remaining crewmembers - Mike Lopez-Alegria, and Expedition 5 crewmembers Valery Korzun, Peggy Whitson and Sergei Treschev - continued packing up gear and hardware in anticipation of tomorrow's landing.

Endeavour has two opportunities to land at the Kennedy Space Center on Wednesday. The first begins with a deorbit burn of the Orbital Maneuvering System engines at 1:42 p.m. CST, followed by a landing at 2:48 p.m. In the event weather prevents a landing on that first opportunity, there is a second opportunity, beginning with a deorbit burn at 3:20 p.m. and resulting in a 4:26 p.m. landing. Preliminary weather forecasts call for the possibility of clouds and rain showers in the vicinity of the three-mile-long landing strip on Wednesday. The backup landing site at California's Edwards Air Force Base was not activated for Wednesday. Endeavour has sufficient consumables to remain in orbit until Sunday.

The seven crewmembers took a few minutes this afternoon to talk with CBS' "Up to the Minute," TV-E Spain and the Tulsa World newspaper. The crew discussed its successful shuttle mission as well as the Expedition 5 crew's to date 181-day experience in space.

Meanwhile, aboard the International Space Station, the Expedition 6 crew -Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin - spent today settling into its new home and unpacking some of the equipment and hardware carried to the station by Endeavour. The crew also enjoyed some time off during its first full day alone on the station.

Endeavour's crew will begin a scheduled eight-hour sleep period at 9:50 p.m. today, waking at 5:50 a.m. Wednesday to prepare for a homecoming to the Kennedy Space Center.

Endeavour has two opportunities to land today. The first begins with a deorbit burn of the Orbital Maneuvering System engines at 1:42 p.m. CST, followed by a landing at 2:48 p.m. In the event weather prevents a landing on that first opportunity, there is a second opportunity, beginning with a deorbit burn at 3:20 p.m. and resulting in a 4:26 p.m. landing.

Preliminary weather forecasts call for the possibility of clouds and rain showers in the vicinity of the three-mile-long landing strip, with a 30 percent probability of weather prohibiting landing. The backup landing site at California's Edwards Air Force Base has not been activated for today. Endeavour has sufficient consumables to remain in orbit until Sunday.

Commander Jim Wetherbee, Pilot Paul Lockhart and Missions Specialists Michael Lopez-Alegria and John Herrington have been in space since Nov. 23. Returning to Earth from the International Space Station with STS-113 is the Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - which has been in space since June 5.

The new crew of the International Space Station - Expedition Six Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin - will spend its day, respectively, reconfiguring the station's computer network and loading new software onto the computers to support the crew's activities for the next four months; checking out the equipment in the Human Research Facility Rack and the station's defibrillator; and performing periodic maintenance on the station's Russian systems.

If Endeavour lands on time, crewmembers are tentatively scheduled to return to the Johnson Space Center in Houston on Friday afternoon.

Flight controllers are now focusing on opportunities for landing on Thursday at the Kennedy Space Center. The next opportunity for a landing by Endeavour would begin with an engine firing at 12:49 p.m. CST Thursday leading to a touchdown in Florida at 1:54 p.m. CST. A second opportunity to land tomorrow also is available beginning with an engine firing at 2:26 p.m. CST leading to touchdown at 3:30 p.m. CST.

Flight controllers plan to monitor weather forecasts for Florida overnight before making a decision early tomorrow on whether to pursue Thursday's landing opportunities. The alternate shuttle landing site at Edwards Air Force Base in California will not be considered on Thursday.

Endeavour has enough supplies to remain in orbit until at least Sunday if necessary. The current weather forecast for a Thursday landing calls for possible clouds and rain that could be unacceptable.

Aboard Endeavour are Commander Jim Wetherbee, Pilot Paul Lockhart, Mission Specialists Mike Lopez-Alegria and John Herrington and the returning International Space Station Expedition 5 crew of Commander Valery Korzun, Science Officer Peggy Whitson and Flight Engineer Sergei Treschev. Wetherbee, Lockhart, Lopez-Alegria and Herrington have been aloft since Nov. 23. Korzun, Whitson and Treschev have been in orbit since June 5.

There are two opportunities for Endeavour to return home to Florida on Friday. The first begins with an engine firing at 11:51 a.m. Central Time leading to a 12:57 p.m. touchdown in Florida. A second opportunity is available with a 1:27 p.m. deorbit burn leading to a 2:33 p.m. landing.

Flight controllers will continue to monitor weather forecasts throughout the day. Preliminary forecasts indicate a continuing chance of clouds and rain over the next 24 hours. The alternate shuttle landing site at Edwards Air Force Base in California will not be called up for support Friday. Endeavour has enough supplies to remain in orbit until at least Sunday if necessary.

If weather does not permit a landing on the first opportunity, there is a second, with a deorbit burn at 1:27 p.m. resulting in a 2:33 p.m. Central Time landing.

Preliminary forecasts for today continue to show low cloud ceilings, possible windy conditions and rain at the Florida landing site. A clearing trend is expected over the next 24 hours with improved conditions in the vicinity of the Kennedy Space Center on Saturday. The alternate shuttle landing site at Edwards Air Force Base in California will be called up for support as well on Saturday.

There are two landing opportunities available at both the Kennedy Space Center and Edwards Air Force Base on Saturday, if required. The first of two opportunities in Florida would see Endeavour land at 1:37 p.m. Central Time, with a second opportunity at 3:14 p.m. Central. The times for a California landing are 4:45 p.m. Central and 6:22 p.m. Central.

Endeavour's seven-member crew includes Commander Jim Wetherbee, Pilot Paul Lockhart, Mission Specialists Mike Lopez-Alegria and John Herrington, and the returning International Space Station Expedition Five crew of Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev. Korzun, Whitson and Treschev are now in their 184th day in space.

Aboard the International Space Station, the Expedition Six crew is completing its first week in orbit. Commander Ken Bowersox, Flight Engineer Nikolai Budarin and NASA ISS Science Officer Don Pettit have been busy at work stowing away the supplies and hardware carried to orbit by Endeavour. They also are preparing for Thursday's scheduled 6 1/2 hour-long spacewalk to be conducted by Bowersox and Budarin. NASA Television coverage of the spacewalk begins at 7 a.m., with the start of the spacewalk slated for 8 a.m. Central.

There are a total of four landing opportunities on Saturday, two in Florida and two at Edwards Air Force Base in California. The Kennedy Space Center remains the primary landing site, with improved weather conditions predicted. Preliminary forecasts at KSC currently show the potential for continuing cloud cover, but generally improved conditions. Weather at Edwards Air Force Base is expected to be acceptable to support a landing.

The first opportunity for Endeavour to return to Florida would see a deorbit burn at 12:32 p.m. Central Time with landing at 1:37 p.m. Central. The second opportunity of the day begins with a deorbit firing of Endeavour's engines at 2:09 p.m. with landing at 3:15 p.m. Central. If weather conditions require Endeavour to land at the alternate site in California, the first opportunity would be at 4:45 p.m., with a second opportunity at 6:22 p.m. Central.

Flight controllers will carefully monitor weather forecasts on both coasts overnight as they prepare to bring Endeavour home Saturday. A landing tomorrow will conclude a 185-day stay in space for the returning Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - and a 14-day mission for the STS-113 crew of Commander Jim Wetherbee, Pilot Paul Lockhart, and Mission Specialists Mike Lopez-Alegria and John Herrington.

This is the fourth day of landing attempts for Endeavour. There are four landing opportunities available today, the first two opportinuties in Florida and the later two in California. The forecast for the Kennedy Space Center today calls for a slight chance of low clouds and fairly strong winds predicted to calm as the day progresses.

The first opportunity for Endeavour to return to Florida would see a deorbit burn at 12:32 p.m. Central Time with landing at 1:37 p.m. Central. The second opportunity of the day begins with a deorbit firing of Endeavour's engines at 2:09 p.m. with landing at 3:15 p.m. Central. If weather conditions require Endeavour to land at the alternate site in California, the first opportunity would begin with an engine firing at 3:41 p.m. Central leading to touchdown at 4:45 p.m. Central. The second California opportunity would begin with an engine firing at 5:18 p.m. Central leading to a touchdown at 6:22 p.m. Central.

A landing today will conclude a 185-day stay in space for the returning Expedition Five crew - Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev - and a 14-day mission for the STS-113 crew of Commander Jim Wetherbee, Pilot Paul Lockhart, and Mission Specialists Mike Lopez-Alegria and John Herrington.

Commander Jim Wetherbee guided Endeavour to a touchdown on KSC's shuttle runway at 1:37 p.m. Central, completing a 5.74-million-mile journey that added a new segment to the space station's growing backbone and exchanged resident space station crews. Endeavour's landing completed the final shuttle mission of the year and brought home the station's Expedition Five crew -- Commander Valery Korzun, Science Officer Peggy Whitson and Flight Engineer Sergei Treschev. The Expedition Six crew -- Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin -- remain on the International Space Station, beginning a three-month stay. Ending a 14-day flight aboard Endeavour today were Wetherbee, Shuttle Pilot Paul Lockhart and Mission Specialists Mike Lopez-Alegria and John Herrington.

Official landing times for Endeavour include main gear touchdown at 1:37:12 p.m. Central which equates to 13 days, 18 hours, 47 minutes and 25 seconds Mission Elapsed Time. Nose gear touch down occurred at 1:37:23 p.m. Central or 13 days, 18 hours, 47 minutes and 36 seconds Mission Elapsed Time. Wheels stop for Endeavour occurred at 1:38:25 p.m. Central or 13 days, 18 hours, 48 minutes and 38 seconds Mission Elapsed Time.

The Expedition Five crew and Endeavour's crew will return to Houston's Ellington Field on Monday, December 9. A welcome home ceremony is planned beginning at 3 p.m. Central at Hangar 990.

Early this week Commander Ken Bowersox, Flight Engineer Nikolai Budarin, and NASA ISS Science Officer Don Pettit completed the first of three rounds of sample collection for a Human Life Sciences experiment looking into the risk of kidney stone formation in astronauts during extended spaceflights. The investigation, developed by Peggy Whitson before her assignment on the Expedition 5 crew, tests whether the use of potassium citrate, which has been used successfully to combat kidney stones in people on Earth, decreases the occurrence of stone formation in astronauts during long periods in a microgravity environment. This week Bowersox, Budarin and Pettit also finished their first monthly session with an apparatus that measures pulmonary function, gathering data on possible adverse impacts from being in zero-g or in the lower-than-normal atmospheric pressure inside a spacesuit during a spacewalk.

On Thursday Pettit completed a scheduled monthly check of the GASMAP equipment in the Human Research Facility rack. The Gas Analyzer System for Metabolic Physiology analyzes gases in a crewmember's breath so flight surgeons can assess aerobic capacity; it also measures cardiac output and lung volume and efficiency.

Flight control teams in Houston and Moscow continue to work on rescheduling the increment's only planned spacewalk, which was postponed this week. The spacewalk by Bowersox and Budarin, which includes tasks to continue outfitting the station's new P1 Truss but is not time-critical, is being considered for late January. The station's Expedition 5 crewmembers—Commander Valery Korzun, NASA ISS Science Officer Peggy Whitson, and Flight Engineer Sergei Treschev—completed their 185-day spaceflight Dec. 7 when the space shuttle Endeavour and its crew, after waiting out three days of poor weather, landed at Kennedy Space Center. Endeavour delivered Expedition 6 and the P1 Truss during its two-week mission. Korzun, Whitson and Treschev returned to the Johnson Space Center in Houston Monday to continue their physical rehabilitation after six months in weightlessness.

Malenchenko and Lu answered questions posed by reporters from CNN, CBS and KCRA-TV, Sacramento, Calif., during breaks in their Progress unloading and scientific research. Lu even took a moment in one interview to play a short rendition of the "Peanuts" theme on a keyboard he has been practicing with on orbit.

But for the most part, it was a busy week of work as the pair unloaded about two tons of food, water, clothing, office supplies, environmental system replacement parts and experiment gear from Progress 11. The Russian cargo craft automatically docked to the Pirs Docking Compartment on June 11; the Expedition 7 crew began unloading the cargo ship last Friday. Water transfers were effected using hoses and a portable electric pump that moved about 210 liters of drinking water from the Progress into a bladder in the Zvezda Service Module. Each crewmember uses about 2 liters of water per day.

In addition, propellant valves were opened between the Service Module fuel system and the Pirs system to enable fuel to be transferred from the new Progress to Zvezda.

Tuesday, Lu slipped his hands into the Microgravity Science Glovebox to continue work with the Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE) experiment. InSPACE is investigating a type of "smart fluids" that researchers hope will help improve braking and vibration damping systems. Lu beamed down video of his setup and deactivation of the experiment, as well as shots of the bright green liquid inside the experiment chamber. Scientists at the Payload Operations Center at Marshall Space Flight Center in Huntsville, Ala., monitored the experiment and the associated video.

Next week, the crew will continue unpacking the Progress and transferring fuel to Zvezda's tanks. Also on the schedule is a ship-to-ship conversation between the crew and Peggy Whitson, the Expedition 5 science officer who is commanding a 14-day underwater research mission as part of the NASA Extreme Environment Operations (NEEMO) project. That conversation will be broadcast live on NASA TV at 11:25 a.m. CDT Wednesday, June 25, between the ISS and the Aquarius underwater lab off the coast of Key Largo, Fla.

InSPACE stands for Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions. The experiment, in the U.S. laboratory Destiny, looks at fluids that contain small particles that can be magnetized. The research could result in improved brake or vibration dampening fluids, or even improved systems to make buildings better able to survive earthquakes.

Malenchenko spent part of today loading the Progress 10 unpiloted supply craft docked to the aft port of Zvezda with ISS discards. With its load of trash, that progress will be undocked in October and burn up in the Earth's atmosphere. A similar craft, Progress 11, arrived at one of the Zarya docking ports on June 11 and crewmembers have worked to unload it.

Lu and Malenchenko on Monday and Wednesday replaced the flexpacks in the canisters of the resistive exercise device (RED). The flexpacks provide the resistance as crewmembers exercise major muscle groups. The new flexpacks were brought up on Progress 11.

Tuesday Lu calibrated an ultrasound device and downlinked ultrasound images from the instrument in the Human Research Facility, a rack in the U.S. laboratory. Malenchenko did maintenance on the Zarya module's cooling system, replacing a pump in one of the cooling loops.

Medical tests continued throughout much of the week. On Wednesday Lu set up and calibrated the Portable Clinical Blood Analyzer (PCBA). The next day each crewmember performed health status checks on one another using a variety of equipment, including the PCBA.

The two crewmembers talked on Tuesday with reporter Stephen Young of SpaceflightNow.com. Wednesday they held a ship-to-ship chat with the six-member Aquarius crew of the NASA Extreme Environment Mission Operations (NEEMO). Peggy Whitson, the first NASA ISS science officer, who flew on ISS Expedition 5 from June to November 2002, commands the Aquarius crew. And on Thursday they talked with people from the NASAexplorers website at NASA's Marshall Space Flight Center in Huntsville, Ala.

Saturday and Sunday will be days off, though exercise and necessary station maintenance will be performed both days. On Sunday they will have a chance to talk with their families in private family conferences. Another InSPACE run is scheduled for Monday, as is data transfer with the EXPRESS Rack 1 in the Destiny laboratory.

Malenchenko and Whitson, together with visiting Korean astronaut Yi, who had been delivered to the ISS by Soyuz TMA-12, undocked from the station aboard Soyuz TMA-11 at 05:06 GMT on 19 April 2008. Following the deorbit burn at 07:40 GMT the aft service module of the Soyuz failed to separate and the spacecraft began re-entry in a reversed position, with the forward hatch taking the initial re-entry heating. As was the case with Soyuz 5 in 1970, the connections with the service module finally melted away, and the freed capsule righted itself aerodynamically with the heat shield taking the brunt of the re-entry heating. However the crew experienced a rough ride, a ballistic re-entry of over 8 G's force, smoke in the cabin, a failure of the soft landing system, and a very hard landing. They landed 470 km short of the target point at 50 deg 31" N, 61 deg 7" E at 08:29 GMT. A small grass fire was started at the landing point and the injured crew had to be helped from the capsule by passers-by. Malenchenko and Whitson suffered no permanent injury, but Yi was hit by Whitson's personal effects bag on impact and required physical therapy for neck and spine injuries.

After setting up the video camera gear for covering their CEVIS cycle ergometer workout, Peggy Whitson and Dan Tani activated the OUM-PFE (Oxygen Uptake Measurement - Periodic Fitness Evaluation) equipment at the HRF-2 (Human Research Facility 2) rack, including the HRF PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), Mixing Bag System and GDS (Gas Delivery System). Both crewmembers then completed the evaluation protocol, wearing HRMs (Heart Rate Monitors), with each one in turn acting as subject and operator, obtaining measurements on themselves on the CEVIS cycle ergometer. (The operations were documented with photo and video. Later, Peggy and Dan updated the evaluation protocol, deactivated & stowed the gear, including photo/video equipment, and powered down the OUM-PFE laptop. Purpose of OUM-PFE is to measure aerobic capacity during exercise within 14 days after arrival on ISS, and once monthly during routine PFEs. The data allows exercise physiologists & flight doctors to assess the crew's health & fitness and to provide data for modifying & updating crew-specific exercise regimes. PFE-OUM is a collaborative effort between NASA and ESA (European Space Agency).)

The crew completed the mandatory CHeCS (Crew Health Care Systems) emergency/contingency medical OBT (on-board training) drill, a one-hour U.S. exercise designed to refresh crewmembers' acuity in applying HMS (Health Maintenance System) equipment like ACLS (Advanced Cardio Life Support) in an emergency. (The drill gives the crew the opportunity to work as a team in resolving a simulated medical emergency onboard ISS and to refresh their memory of on-orbit stowage & deployment locations, equipment use, and procedures. Setting up (but not actually operating/manipulating) onboard equipment such as the RSP (Respiratory Support Pack), ALSP (Advanced Life Support Pack), intubation kit, HMS defibrillator, all stowed in the Lab CHeCS rack, and the CMRS (Crew Medical Restraint System), Peggy, Yuri and Dan stepped through the ACLS algorithm manual to resolve a simulated medical emergency onboard ISS. Objectives of the exercise include practicing communication and coordination necessary to perform medical emergency procedures, locating appropriate emergency medical components, and determining each crewmember's individual method of delivering CPR (cardio-pulmonary resuscitation) in zero-G.)

EVA-11 'Bravo' was completed fully successfully in 7 hrs 16 min, accomplishing all objectives plus several get-ahead tasks. During the spacewalk, CDR Peggy Whitson (EV1) and FE-2 Dan Tani (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, connected and configured one half of the Node-2 fluid, power, and cooling jumpers. The other half will be done on EVA-12 'Charlie' on 11/24 (Saturday).

(The test, using the RSS2 laptop, consisted of switching from the regular 128-byte TM frame to a 206-byte format, for the ground to run tests overnight from RGS (Russian Ground Sites). Tomorrow, in part 2 the FE-1 will reconfigure the BSR-TM back to 128-byte format.)

Afterwards, Malenchenko recorded the post-EVA radiation readings from the Russian EMU-worn plus one background 'Pille-MKS' dosimeters in a log table for subsequent downlink to the ground.

Starting preparations of their next spacewalk, EVA-12 'Charlie' on 11/24 (Saturday), CDR Whitson and FE-2 Tani -

CDR Whitson & FE-1 Malenchenko started off on today's light-duty schedule with another standard 30-min Shuttle RPM (R-bar Pitch Maneuver) skill training, Peggy's third, Yuri's fourth, using DCS-760 digital still cameras with 400 & 800mm lenses at Service Module (SM) windows 6 & 8 to take imagery of documented EO (Earth Observation) targets facing the velocity vector (in flight direction). Afterwards, Peggy downlinked the obtained images to the ground for analysis, to be discussed at a subsequent tagup. (The skill training prepares crewmembers for the bottomside mapping of the Orbiter at the arrival of STS-122/1E in December. During the RPM at ~600 ft from the station, the ISS crew will have only ~90 seconds for taking high-resolution digital photographs of all tile areas and door seals on the Atlantis from SM windows 6 & 8, to be downlinked for launch debris assessment. Thus, time available for the shooting will be very limited, requiring great coordination between the two headset-equipped photographers and the Shuttle.)

Additional Details: ISS On-Orbit Status 11/22/07.

(The test, controlled from the RSS2 laptop, began 11/21 with Yuri switching from the regular 128-byte TM frame to a 206-byte format, for TsUP to run tests from RGS (Russian Ground Sites). Today, in Part 2 as per plan the FE-1 returned the BSR-TM to the nominal 128-byte format.)

Malenchenko also transferred measurements & imagery from the ESA/RSC-Energia experiment ALTCRISS (Alteino Long Term monitoring of Cosmic Rays on the ISS) to OCA for subsequent downlink to the ground, after yesterday's first repositioning of the spectrometer. (ALTCRISS uses the AST spectrometer to monitor space radiation in the Russian segment (RS).)

Node-2 Harmony is ready to accept Columbus!

EVA-12 'Charlie' was completed fully successfully in 7 hrs 4 min, accomplishing all objectives & get-ahead tasks.
As a consequence, Node-2 Harmony was fully activated by the ground, one day earlier than originally planned, enabling interior activations by the crew tomorrow.

During the spacewalk, CDR Peggy Whitson (EV1) and FE-2 Dan Tani (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, connected and configured the second half of the Node-2 fluid, power, and cooling jumpers (the first half was accomplished on EVA-11 'Bravo' on 11/20).

Ahead: Week 6 of Increment 16.

The FE-1 started his day by recording post-EVA radiation readings from the Russian 'Pille-MKS' dosimeters in the two spacesuits worn by Whitson & Tani during yesterday's spacewalk and from one background dosimeter. Measurements were logged in a table for subsequent downlink to the ground.

In the SM (Service Module), Malenchenko afterwards activated the Kenwood D700 amateur radio station and started the program for the Russian SHADOW-BEACON (Tenj-Mayak) experiment. (Objective of the experiment is the automatic retranslation of time tag (pre-planned executable) packets from ground stations. SHADOW (or ECLIPSE), sponsored by Roskosmos and its leading Moscow research organization TSNIIMASH (Central Research Institute of Machine Building), employs VHF amateur radio (ham) operators around the globe (via ARISS/Amateur Radio on ISS) to help in observing refraction/scattering effects in artificial plasmas using the method of RF (radio frequency) sounding in space experiments under different geophysical conditions. This is the experiment's second run, after Flight Engineer Mikhail Tyurin conducted it first on Expedition 14 in November 2006.)

ff-duty day for CDR Whitson, FE-1 Malenchenko and FE-2 Tani. Underway: Week 6 of Increment 16. Having passed the Day 30 mark in her flight, CDR-16 Whitson began her second session with the NASA/JSC experiment NUTRITION w/Repository, for which she had to forego exercising and food intake for eight hours. (After collecting an initial urine sample, Whitson, assisted by Dan Tani, followed it with phlebotomy, i.e., drawing blood samples (from an arm vein) which she first allowed to coagulate in the Repository, then spun in the HRF RC (Human Research Facility/Refrigerated Centrifuge) and finally placed in MELFI (Minus-Eighty Laboratory Freezer for ISS). The RC was later powered off after a temperature reset to limit wear on the compressor, and cleaned (see RC troubleshooting, below). The equipment was then stowed. NUTRITION activities today included the required 24-hour data urine collection by Whitson, by securing samples during the day, all stored immediately in MELFI. The Clinical Nutritional Assessment profile currently required on all U.S. Astronauts collects blood and urine samples preflight and postflight. NUTRITION expands this protocol by also capturing inflight samples and an additional postflight sample. Furthermore, additional measurements are included for samples from all sessions, including additional markers of bone metabolism, vitamin status, and hormone and oxidative stressor tests. The results will be used to better understand the impact of countermeasures (exercise and pharmaceuticals) on nutritional status and nutrient requirements. The Clinical Nutritional Assessment profile (MR016L), first started on two Mir crewmembers and then on all ISS US crews, nominally consists of two pre-flight and one post-flight analysis of nutritional status, as well as an in-flight assessment of dietary intake using the FFQ (Food Frequency Questionnaire). The current NUTRITION project expands MR016L testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

Today she collected another urine sample for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS). The sampling kit was then stowed away. (The current NUTRITION project expands the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

(The FE-2 configured the hardware to allow the ground to perform ground commanding to the MLC (Microgravity Science Glovebox Laptop Computer) for diagnostic testing and to develop recovery steps for the ECU (Electronic Control Unit) to be reprogrammed correctly.)

FE-1 Yuri Malenchenko performed a thorough 2-hr. troubleshooting inspection & verification of the connections of the Russian segment's Onboard Cabling System (BKS) to the FGB's Thermal Control System (SOTR). (Using the Nikon D200 digital camera, Yuri documented the SOTR layout behind panel 215 and checked connector pins for dirt or misalignment.)

This includes inspection and audio function checks of all comm panels (PA) in and between the Service Module (SM), FGB and Docking Compartment (DC1), VHF receiver tests, and an audit of headsets. (The "Voskhod-M" STTS enables telephone communications between the SM, FGB, DC1 and U.S. segment (USOS), and also with users on the ground over VHF channels selected by an operator at an SM comm panel, via STTS antennas on the SM's outside. There are six comm panels in the SM with pushbuttons for accessing any of three audio channels, plus an intercom channel. Other modes of the STTS include telegraphy (teletype), EVA voice, emergency alarms, Packet/Email, and TORU docking support. Last time done 4/15/07 by Yurchikhin & Kotov.)

(After yesterday's hardware setup, leak checking of the electronics box and evacuation of the vacuum work chamber (ZB) with the turbopump, the CDR conducted more testing and calibration, uploaded new software from a USB stick to the payload laptop, checked out the software installation and verified the readiness of the experiment. After additional leak checking on the work chamber during the day, Yuri will deactivate the turbopump tonight at ~4:25pm EST. The experiment is performed on plasma, i.e., fine particles charged and excited by HF (high frequency) radio power inside the evacuated work chamber. Main objective is to obtain a homogeneous plasma dust cloud at various pressures and particle quantities with or without superimposition of an LF (low frequency) harmonic electrical field. The experiment is conducted in automated mode. PK-3+ has more advanced hardware and software than the previously used Russian PKE-Nefedov payload.)

The FE-2 later conducted inflight maintenance on the Node-2 ITCS (Internal Thermal Control System)'s MTL (Moderate Temperature Loop) by adjusting its fluid sampling adapter metering valve and then taking another fluid sample for return to the ground and one for OPA (Ortho-Phthalaldehyde) testing.. Afterwards, Dan repeated the sampling process on the LTL (Low Temperature Loop) side of the Node-2 ITCS. (OPA, an antimicrobial agent, was introduced into the Lab ITCS coolant by the AmiA (Antimicrobial Applicator).)

FE-1 Malenchenko performed monthly maintenance on the Russian IK0501 GA (gas analyzer) of the SOGS Pressure Control & Atmospheric Monitoring System, deactivating the unit and replacing its CO2 filter assembly (BF) with a new unit from FGB stowage (replaced last: 10/29). (After ensuring good seals on the instrument's base and no leaks around the installed filter, Yuri reactivated the GA and stowed the spent BF for disposal. IK0501 is an automated system for measuring CO2, O2, and H2O in the air as well as the flow rate of the gas being analyzed.)

CDR Whitson completed the periodic offloading of the Lab CCAA (Common Cabin Air Assembly) dehumidifier's condensate tank, filling CWC (Contingency Water Container) #1062 with the collected water slated for processing, and putting aside two water samples in sample bags for analysis. (Estimated offload time before termination (leaving ~6 kg in the tank): ~20 min.)

During the spacewalk, Tani (EV1) & Whitson (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, inspected the Stbd (right-side) 1A BGA (Beta Gimbal Assembly) and BMRMM (Bearing Motor Roll Ring Module), followed by a detailed investigation and photo documentation of the Stbd SARJ (Solar Alpha Rotary Joint).
Specifically, the spacewalkers -

Found no obvious signs of external damage on cables or hardware of the BGA & BMRMM that might have caused the repeated tripping of circuit breakers (RPCs/Remote Power Controllers), making it more likely that the issue is internal to the hardware or its electrical system;
Entered into the S5 truss to disconnect some wiring to allow the ground to perform diagnostic continuity tests, and later reconnected the cables;
Temporarily removed 22 protective MLI (Multi-Layer Insulation) covers to inspect the SARJ, its two DLAs (Drive Lock Assemblies), and its 12 TBAs (Trundle Bearing Assemblies), reattaching the covers afterwards,
Found most metal shavings around TBA-4 and TBA-5, i.e., metallic, magnetic contamination on the main gear bearing's outboard angled race ring as well as pitting and abrasions on the ring but no obvious damage on the inboard race ring or on the gear teeth themselves. DLA (Drive Lock Assembly) #2 appeared especially 'ugly', i.e., filled with contamination, and, according to the spacewalkers, the further away from the DLA, the less contamination was observed;
Took photographs, measured the depth of surface pits with a special probe and collected debris samples; and
Deinstalled and removed TBA-5 from its housing under cover #20, using a PGT (Pistol Grip Tool), then brought it inside in a bag for eventual return to Earth aboard STS-122/Atlantis (SARJ can function OK on only 11 TBAs).
(Official start time of the spacewalk was 4:50am EST, 70 minutes ahead of the timeline, ending at 11:46am. Total EVA duration (PET = Phase Elapsed Time) was 6h 56min. It was the 100th spacewalk for ISS assembly & maintenance and the 72nd from the station (28 from Shuttle, 50 from Quest, 22 from Pirs) totaling 436h 3m, and the 4th for Expedition 16 (totaling 28h 11m. During the spacewalk, her fifth, Peggy Whitson set a new record of aggregated EVA time by a woman (of 32h 36m) when she exceeded the 29h 18m held by Sunita Williams. After today's EVA, a total of 121 spacewalkers (90 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 624h 25m outside the station on building, outfitting and servicing. It was also the 122nd spacewalk by U.S. astronauts. The 100th EVA dedicated to ISS assembly & maintenance originally was to have been conducted by Rex Walheim & Hans Schlegel of the delayed STS-122/1E mission.)

Happy 46th Birthday, Yuri Ivanovich!

Last night, Progress M-61/26P successfully undocked from the ISS at 10:59pm EST (hook opening command: 10:57pm). The separation appeared smooth with no vibrations noted. Downlinked video from the cargo vehicle showed that the docking ring surface was nominal. The first separation burn was performed at 11:03pm and a second separation burn followed at 11:09pm. The spacecraft initially moved aft of the station, then forward, overtaking the ISS on a lower (faster) orbit. 26P will remain in orbit in free flight for 3-4 weeks, continuing to phase out in front of the ISS (about 40 km per orbit) as part of a Russian Earth observation experiment.

Additional Details: ISS On-Orbit Status 12/22/07.

Ahead: Week 10 of Increment 16.

With the usual dependability, Progress M-62/27P launched nominally this morning at Baikonur at 2:12am EST. Orbit insertion and 3rd stage separation were nominal at ~2:21:30am. Critical antennae and solar array deployments took place without issue. Docking is scheduled on Wednesday, 12/26 (~3:25am EST). Congrats, Baikonur!

Before breakfast, FE-2 Dan Tani and CDR Peggy Whitson completed their daily access of the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink.

FE-1 Malenchenko serviced the Russian BMP (Harmful Impurities Removal System), starting the "bake-out" cycle to vacuum on absorbent bed #2 of the regenerable dual-channel filtration system. The regen process will be terminated at ~2:45pm EST. (Regeneration of each of the two cartridges takes about 12 hours and is conducted only during crew awake periods. Filter bed 1 was regenerated yesterday.)

Yuri also performed the routine servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM. (Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.)

The crewmembers completed their regular 2.5-hr physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (FE-2), TVIS treadmill with vibration isolation (CDR, FE-1), RED resistive exercise device (CDR, FE-2) and VELO bike with bungee cord load trainer (FE-1).

Afterwards, Peggy copied the exercise data file to the MEC (Medical Equipment Computer) laptop for downlink, including the daily wristband HRM (Heart Rate Monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

At ~1:00pm, Dan Tani had a PFC (Private Family Conference) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-10 laptop).

At ~11:30am, CDT Whitson conducted a teleconference with the Houston Flight Control Team (FCT).

ASN-M Testing: TsUP-Moscow began with tests of the ASN-M Satellite Navigation System over six orbits, without crew involvement. (ASN-M is required for ATV (Automated Transfer Vehicle) 'Jules Verne' prox ops next year.)

Final Approach start: 3:17am
27P Docking at DC1 nadir port: 3:25am
RGS LOS: 3:37am
Progress hooks closed: 3:46am
CEO photo targets uplinked for today again were Polar Mesospheric Clouds (PMC - also known as noctilucent clouds) over selected ground sites (12 minutes for each). Also suggested for Dan Tani were a series of night photographs of city lights. (Use of the footprint of city lights as a proxy for population size and density (in different cultures/economies) is proving out as a workable method of observing population change through time).

Progress M-62 (27P), approaching from below the station, docked nominally at the DC1 Docking Compartment nadir port at 3:14am EST, with automatic AO-VKA orientation antenna retraction, followed by docking probe retraction and hook closure ('sborka') at 3:23am after motion damp-out, while the ISS was in free drift. (Launched 12/23 (2:12am EST), the 27P resupply drone delivered about 2.5 tons of cargo for the ISS crews, including propellants for the Russian thrusters, fresh water, oxygen, food, spare parts, repair gear, life support and science experiment hardware. For the docking, ISS attitude control authority was handed over to Russian MCS (Motion Control System) thrusters at 11:48pm and returned to US Momentum Management at 5:06am. Starting with TV camera activation at ~2:37am (range ~8 km), the KURS TV camera display data overlay failed to show through docking despite attempts by the crew to activate the numerical display. The docking took place nominally, without violation of any joint flight rules, since Malenchenko and Whitson had all numerical data on a laptop before them. Telemetry was also available in TsUP-Moscow.)

Upon wakeup, FE-1 Yuri Malenchenko terminated his fifth MBI-12 SONOKARD experiment session, started last night, by taking the recording device from his SONOKARD sports shirt pocket and later copying the measurements to the RSE-MED laptop for subsequent downlink to the ground. (SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

Dr. Whitson conducted her first clinical blood analysis of the US PHS (Periodic Health Status) with Blood Labs exam. Afterwards, all PHS hardware was stowed again. (The PHS exam, with PCBA (Portable Clinical Blood Analyzer) analysis and clinical evaluation, is guided by special software (IFEP, in-flight examination program) on the MEC (Medical Equipment Computer). While PCBA analyzes total blood composition, the blood's hematocrit is particularly measured by the Russian MO-10 protocol.)

Also before breakfast, Peggy Whitson, Yuri Malenchenko and Dan Tani performed the periodic Russian biomedical routine assessments PZEh-MO-7/Calf Volume Measurement and PZEh-MO-8/Body Mass Measurement (5th for CDR & FE-1, 4th for FE-2), using the IM mass measurement device which Malenchenko afterwards broke down for stowage. (Calf measurements (left leg only) are taken with the IZOG device, a custom-sewn fabric cuff that fits over the calf, using the knee and lower foot as fixed reference pints, to provide a rough index of deconditioning in zero-G and effectiveness of countermeasures. For determining body mass in zero-G, where things are weightless but not massless, the Russian IM "scales" measure the inertial forces that arise during the oscillatory motion of a mass driven by two helical metering springs with known spring constants. By measuring the time period of each oscillation of the unknown mass (the crewmember) and comparing it to the period of a known mass, the crewmember's mass is calculated by the computer and displayed.)

At ~5:00am EST, FE-1 Malenchenko received a 10-min VIP call via S-band from Patriarch Alexis II of the Russian Orthodox Church, speaking from TsUP/Moscow and extending best wishes to the crew on the occasion of today's Orthodox Christmas celebration. (The Russian Orthodox Church celebrates its Christmas 13 days after Western Christmas, on January 7, in accordance with the old Julian calendar. It is a day of both solemn ritual and joyous celebration. Christmas was banned throughout Russia after the 1917 Revolution, along with other religious celebrations, and it wasn't until 75 years later, in 1992, that the holiday was again openly observed. Today, it's once again celebrated in grand fashion, with citizens participating in an all-night Mass in incense-filled Cathedrals amidst the company of the painted icons of Saints, along with a traditional family get-together and special meal on Christmas Eve.)

Later, Yuri completed today's routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM), including ASU toilet facilities systems/replaceables, the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP.

The crewmembers performed their regular 2.5-hr physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (FE-2), TVIS treadmill (CDR, FE-1), RED (CDR, FE-2) and VELO bike with bungee cord load trainer (FE-1).

Afterwards, Peggy Whitson copied the exercise data file to the MEC (Medical Equipment Computer) laptop for downlink, including the daily wristband HRM (Heart Rate Monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

With the Russian O2 (oxygen) generator 'Elektron' turned off since 12/28/07, the FE-1 had time set aside for another 1-hour O2 repress of the cabin atmosphere from Progress M-62/27P storage tankage, if required. Yesterday's repress added about 8 mmHg of O2 into the ISS as per plan. (The Elektron will remain powered down until 1/9/08 to conserve hardware lifetime. During this time, the station will be periodically repressurized with oxygen from Progress 27P.)

A new entry still on discretionary US 'job jar' task list for Peggy and Yuri is 'ghosting' an updated personal image with their preferred material on a 60GB hard disk in an A31p laptop UltraBay Adapter reserved as their CPSD (Crew Personal Support Disk), a 45-min task for each.

Also on Whitson's voluntary task list, at her convenience, is an audit of rack locations, using the IMS (Inventory Management System). (The audit function, introduced with the implementation of IMS software version 2.0, allows the crewmember to set up audits of bags, kits, containers and stowage locations on the laptop.)

A third new item on the 'job jar' task list is for FE-2 Tani to continue his crew departure preparations.

The two flight engineers were scheduled for PFCs (Private Family Conferences) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-9 laptop), Yuri at ~6:20am EST, Dan at ~11:50am.

No CEO photo targets uplinked for today.

The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)

Working in the DC1 Docking Compartment, FE-1 Malenchenko, later joined by CDR Whitson, started a three-day maintenance activity on three Russian Orlan-M spacesuits (#25, #26, #27), first initiating discharge of 825M3 Orlan battery pack #1, then scrubbing and degassing the Orlan water loops, followed by the coolant loops in the DC1 and SM PkhO (Service Module Transfer Compartment) BSS Orlan Interface Units. (Functional inspection & checkout of the suits and their spare parts, including bladder leak tests, are scheduled tomorrow & Thursday.)

The FE-2 worked in the Airlock (A/L), starting on a lengthy (2h 25m) troubleshooting procedure on the EACP (EVA/EMU Audio Control Panel), first setting up comm from the A/L, then activating the EACP and connecting it via the 'low clearance' Y-cable to ATU-4 (Audio Terminal Unit, #4) and ATU-6 on the A/L Avionics Rack. After initial testing, the EACP was turned off again. (ATU-6 was installed by Clay Anderson on 10/11/07 in place of a failed unit, and the failed ATU-6 was returned on 10A. The new ATU-6 has been experiencing periodic lockups and PBIT (passive built-in test) faults. Engineering analysis and testing indicate that these issues may be caused by improperly mated J3 & J4 connections, a problem with the address connector, or a dirty fiber-optic connector. There are 3 ATUs in the A/L, one of which must be functional for EVAs, so long as the suited EVA crew has established UHF (Ultra High Frequency) radio communication.)

(Each day, Yuri has selected higher symmetrical (shoulders) & asymmetrical (chest & back) loads (~20-30 kgf), after calibrating the system with no load on the suit's internal tension straps. Load data are then collected by the SIN electronics (via analog-to-digital converters) and downloaded to a A31p laptop three times daily, followed by downlink to the ground via BSR-TM.)

FE-2 Tani performed his daily status check on the BCAT-3 (Binary Colloidal Alloy Test-3) science payload, running by itself in Node-2 since 12/13/07 (briefly interrupted for EVA-13 photo support). (The status check, conducted on the last image taken by the DCS 760 digital still camera which is controlled by EarthKAM software on an A31p laptop, is to verify proper image focus and camera alignment. The SSC (Station Support Computer) is taking photography of the phase separation occurring in the BCAT Sample 3, with the photo flash going off every half hour.)

Malenchenko completed today's routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM), including ASU toilet facilities systems/replaceables, the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP.

The crewmembers performed their regular 2.5-hr physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR, FE-2), TVIS treadmill (FE-1), RED (CDR, FE-2) and VELO bike with bungee cord load trainer (FE-1).

The CDR and FE-2 each had their weekly PFC (Private Family Conference) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-10 laptop), Dan at ~9:05am EST, Peggy at ~12:00pm.

Working off his discretionary 'time permitting' task list, Yuri conducted another session of the Russian "Uragan" (hurricane) earth-imaging program, using the Nikon D2X digital camera with 800 mm focal length lens. (Targets uplinked for today were Patagonia Glaciers and Icebergs in the Drake Passage.)

A second job item on the FE-1's voluntary list for today was another KPT-3 session to make observations and take aerial KPT-3 photography of environmental conditions for Russia's Environmental Safety Agency (ECON) using the Nikon D2X digital camera with SIGMA 300-800mm telephoto lens.

Task items on Peggy's and Dan's discretionary 'job jar' task list today were (1) a thorough review of uplinked draft material on the BMRRM (Bearing Motor Roll Ring Module) hardware and EVA-14 procedures for its upcoming R&R, (2) an audit of CTB (Cargo Transport Bags) and their contents, and (3) installation of a ground wire on the PFA (Portable Fan Assembly).

No CEO photo targets uplinked for today.

CDR Whitson & FE-2 Tani started out with the daily reading of SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment data accumulated during the night, for logging and filling in questionnaire entries in the SLEEP session file on the HRF-1 laptop for downlink. (To monitor the crewmembers' sleep/wake patterns and light exposure, Dan and Peggy wear a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)

Preparatory to today's pump R&R (Removal & Replacement) of the EHS VOA (Environmental Health Systems/Volatile Organic Analyzer), CDR Whitson rotated the CHeCS rack down for some AAA(Avionics Air Assembly) fan/filter and smoke detector cleaning, before FE-2 Tani performed the VOA IFM (Inflight Maintenance), with filter inspection, preceded and followed by taking CSA-O2 (Compound Specific Analyzer-Oxygen) readings in the affected rack areas. (If the O2 percentage was between 15.7% - 24.1%, Dan was Go to proceed. If not, the ground had steps to be taken to ventilate the area. Ground analysis has shown that the secondary seals in QDs (Quick Disconnects) in the Nitrogen/Oxygen systems do not always seal properly, which can result in an increased N2/O2 concentration behind panels & racks with no ventilation. The CHeCS (LAB1D4) is one of these racks.)

Also before breakfast, Peggy Whitson, Yuri Malenchenko and Dan Tani performed the periodic Russian biomedical routine assessments PZEh-MO-7/Calf Volume Measurement and PZEh-MO-8/Body Mass Measurement (6th for CDR & FE-1, 5th for FE-2), using the IM mass measurement device which Malenchenko afterwards broke down for stowage. (Calf measurements (left leg only) are taken with the IZOG device, a custom-sewn fabric cuff that fits over the calf, using the knee and lower foot as fixed reference pints, to provide a rough index of deconditioning in zero-G and effectiveness of countermeasures. For determining body mass in zero-G, where things are weightless but not massless, the Russian IM "scales" measure the inertial forces that arise during the oscillatory motion of a mass driven by two helical metering springs with known spring constants. By measuring the time period of each oscillation of the unknown mass (the crewmember) and comparing it to the period of a known mass, the crewmember's mass is calculated by the computer and displayed.)

Ahead: Week 14 of Increment 16.

For today's VolSci (Voluntary Weekend Science) program, CDR Whitson continued her work with the MSG (Microgravity Science Glovebox) and the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment, today conducting runs #18, #19, and #20, then powered down the payload and switched the MSG to standby. (After activation of MSG plus InSPACE & InSPACE-2 equipment, Peggy checked on alignment & focusing of MSG video cams, switched the magnetic field between runs, today pulsing the field at 2 Hz (Hertz) instead of 20 Hz as she did previously. Peggy also repositioned the sample vial (VA-004) by 90 deg, used camera 2 & recorder 2 in the vial position 2 starting with run #19, changed out video recorder tapes and later deactivated InSPACE & MSG. InSPACE, conducted last in June 2006 by Jeff Williams on Increment 13, obtains basic data on magnetorheological fluids, i.e., a new class of "smart materials" that can be used to improve or develop new brake systems, seat suspensions robotics, clutches, airplane landing gear, and vibration damper systems. The dispersed particles are contained in CAs (Coil Assemblies) in the MSG that subject them to electric fields of certain strength and frequencies.)

FE-2 Dan Tani completed his daily status check on the BCAT-3 (Binary Colloidal Alloy Test-3) science payload, running by itself in Node-2 since 12/13/07 (briefly interrupted for EVA-13 photo support).

At ~9:30am EST, Yuri had his PFC (Private Family Conference) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-10 laptop).

At ~2:22pm, Dan had his PFC.

With the Elektron-VM O2 (oxygen) generator currently off, a 5-min cabin air refresh is to be performed by the FE-1 (off his voluntary task list) from Progress M-62/27P storage (SrPK) as required.

MPC HDTV Update: Dan Tani was lauded by the ground for his great work on 1/17 verifying the MPC HDTV (Multi-Purpose Converter/High-Definition TV) capability all the way to the NASA TV satellite. The test was very successful, yielding an overall end-to-end audio latency (delay) for the MPC System of 3.2 seconds. This is the delay from the crewmember to JSC/MCC-H to NASA Headquarters and out to the NASA TV satellite in high definition, i.e. the sum total of the audio delay the interviewer and interviewee will "feel" during an interactive event. This Japan/JAXA originated system will be utilized soon for downlink messages and in-flight interviews based on client capability.

No CEO photo targets uplinked for today. (Due to the Martin Luther King Federal Holiday tomorrow (1/21), the next CEO observations will be conducted on 1/23 (targets uplinked 1/22).)

CDR Whitson & FE-2 Tani started out with the daily reading of SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment data accumulated during the night, for logging and filling in questionnaire entries in the SLEEP session file on the HRF-1 laptop for downlink.

Upon wakeup, FE-1 Yuri Malenchenko terminated his eighth MBI-12 SONOKARD experiment session, started last night, by taking the recording device from his SONOKARD sports shirt pocket and later copying the measurements to the RSE-MED laptop for subsequent downlink to the ground. (SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

FE-1 Malenchenko finished Part 2 of his first stress test plus saliva and blood sampling of the ESA/Russian biomed experiment 'IMMUNO' (Neuroendocrine & Immune Responses in Humans During & After Long Term Stay at ISS), today completing remaining urine sample collections. Specimens were then stowed in a special urine containment bag (blood samples were secured yesterday in the MELFI {Minus Eighty Degree Celsius Laboratory Freezer for ISS} in cold packs). (IMMUNO is a 24-hr. test of human immune system changes, with the objective to investigate immune neuro-endocrine reactions in the space environment by studying samples of saliva, blood and urine using collection kits and the biomedical (MBI) protection kit. Also included are entries in a fluid/medications intact log, and a stress-test questionnaire to be filled out by the subject at begin and end of the first day.)

This is a periodic service task.

Additional Details: ISS On-Orbit Status 01/28/08.

With the Elektron-VM O2 (oxygen) generator currently off, a one-hour cabin air refresh was to be performed by the FE-1 from Progress 27P storage (SrPK) if required.

CDR Whitson conducted the periodic (every two weeks) 10-min inspection of the RED (Resistive Exercise Device) canister cords and accessory straps as well as the canister bolts for re-tightening if required.

Malenchenko completed today's routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables.

Working off his 'time permitting' discretionary job list, Yuri performed the daily 20-min. IMS maintenance, updating/editing its standard 'delta file' including stowage locations, for the regular weekly automated export/import to its three databases on the ground (Houston, Moscow, Baikonur).

At ~8:45am EST, the crew conducted a teleconference with the Shuttle crew of STS-122/1E, scheduled for launch on 2/7.

At ~9:40am, Peggy, Dan and Yuri tagged up with EVA specialists at MCC-H to discuss final arrangements for tomorrow's EVA-14 spacewalk.

Spending time in the Airlock (A/L) for final preparations for EVA-14, Peggy Whitson and Dan Tani -

Configured the DCS-760 digital camera and flash attachment to be taken outside,
Recharged three batteries for the EVA EMU-prebreathe period, to be installed in the EVA photo flash unit and EVA camera just prior to the spacewalk (when off station power),
Prepared the A/L EL (Airlock Equipment Lock) for the Campout & spacewalk,
Tagged up with ground specialists at ~9:40am EST for reviewing EVA particulars, and
Underwent the standard pre-EVA PMC (Private Medical Conference) via S- & Ku-band audio/video.
Yuri prepared three Russian 'Pille-MKS' radiation dosimeters, recorded their dosages and equipped each of the two EMUs (Extravehicular Mobility Unit) with a radiation sensor (A0309/CDR & A0310/FE-2). (A third sensor, A0308, was placed in the SM on the PULT reader for background readings.)

The CDR powered down the ham radio equipment in SM (Service Module) and FGB at ~12:30pm to prevent RF interference with the EMUs during the spacewalk. Peggy also closed the protective Lab science window shutters.

The crewmembers completed their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR, FE-2), TVIS treadmill (FE-1, FE-2), RED resistive exercise device (CDR, FE-2), and VELO bike with bungee cord load trainer (FE-1).

Whitson then transferred the crew's exercise data file to the MEC for downlink, as well as the daily wristband HRM data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

At ~2:50pm EST, Whitson and Tani began their overnight Campout prebreathe and lockout in the A/L. With METOX (Metal Oxide) canisters for CO2 removal in the A/L, the two spacewalkers performed PBA (Portable Breathing Apparatus) mask prebreathe for denitrogenation, while readying their equipment, then depressed the A/L to 10.2 psi for the campout.

After the 8.5-hr sleep period before the spacewalk, the A/L CL (Crewlock) hatch will be cracked at ~1:00am EST for a hygiene break/with mask prebreathe for Whitson and Tani, after spending the night on 10.2 psi. Around 2:10am, the hatch will be closed again by IV Yuri Malenchenko for EVA preparations in 10.2 psi, followed by EMU purge & prebreath. Afterwards, Yuri will support CL depressurization and EV1 & EV2 will egress (~5:20-5:30am).

CEO photo targets uplinked for today were IPY - Aurora Borealis; Heard Island, S. Indian Ocean (clear weather windows continue to be present in the region of Heard Island at the time of the ISS orbit pass. Looking to the right of track as ISS approached Antarctica. Mapping photography of the island was requested to capture snow and ice extent. The island of Kerguelen may also be visible to the northwest of Heard Island), and Patagonian Glaciers, S. America (this orbit track provided a traverse across the central portion of the Patagonian ranges. Overlapping, nadir mapping frames of glaciers on the western side of the mountains were requested).

Atlantis lifted off from the Kennedy Space Center on mission STS-122 at 1:45 p.m. CST. Aboard the shuttle are Commander Steve Frick, Pilot Alan Poindexter and Mission Specialists Leland Melvin, Rex Walheim, Stanley Love, Hans Schlegel and Leopold Eyharts. Schlegel and Eyharts are European astronauts.

Atlantis is in excellent condition. The shuttle is scheduled to dock with the International Space Station on Saturday. On Friday, the crew will use the shuttle's robotic arm to inspect Atlantis' heat shield on the wing leading edges and nose. They also will check the spacesuits that will be used for three spacewalks during the mission.

After Atlantis arrives at the station, Eyharts will become a member of the Expedition 16 crew, joining Commander Peggy Whitson and Flight Engineer Yuri Malenchenko. Flight Engineer Dan Tani, who has been aboard the station since October 2007, will return to Earth on Atlantis.

The launch of Atlantis is the 121st space shuttle launch and the 29th flight of Atlantis. The Columbus module is Europe's primary contribution to the space station. Columbus will host experiments in life, physical and earth sciences.

The shuttle crew will begin a sleep period at 7:45 p.m. CST and awaken at 3:45 a.m. CST Friday to begin their first full day in space.<

The crew's work/sleep cycle was shifted once more in preparation for Atlantis 1E arrival, to 5:00am-8:15pm.

STS-122/Atlantis continues its catch-up flight for tomorrow's FD3 ISS docking at ~12:25pm EDT, to begin ISS Stage 1E. (Catch-up rate ~480 nmi. per revolution of ~92 min.). (Hatch opening: expected at ~1:35pm, followed by: Safety Briefing, OBSS (Orbiter Boom Sensor System) handoff from SSRMS (Space Station Remote Manipulator System) to SRMS (Shuttle RMS) at ~4:30pm, Soyuz seat liner transfer (for the Tani/Anderson exchange), and preparations for the first spacewalk, EVA-1, by EV1 Walheim & EV2 Schlegel, on 2/10, preceded by their overnight Campout tomorrow night in the Airlock (A/L) for denitrogenation/pre-breathe. Objectives of the nominal 11-day mission: Delivering & installing the Columbus module, delivering new ISS-16 crewmember LÃ(c)opold Eyharts & bringing Dan Tani back home, and conducting a total of three EVAs. Landing will nominally take place at KSC on FD10 (2/18) at ~9:59am EST.)

Installing the laboratory, named for Christopher Columbus, is the primary goal of this 121st space shuttle mission. It will add 2,648 cubic feet of pressurized volume, four science experiment racks and one storage rack to the space station.

This morning's wakeup song, 'The Book of Love,' performed by Peter Gabriel, was played for European Space Agency astronaut Leopold Eyharts at 3:45 a.m. CST. Eyharts will become a member of the Expedition 16 crew, replacing Flight Engineer Dan Tani, after Atlantis arrives at the space station Saturday.

Today Atlantis Commander Steve Frick and his crewmates, Pilot Alan Poindexter and Mission Specialists Leland Melvin, Rex Walheim, Stanley Love, Hans Schlegel and Eyharts will perform an inspection of Atlantis' heat shield using the shuttle's robotic arm and the Orbiter Boom Sensor System. They'll also check out the tools they need for Saturday's rendezvous and docking to the station and install a centerline camera in the shuttle's orbiter docking system.

Spacewalkers Walheim, Schlegel and Love will prepare spacesuits that they will wear during the mission's three spacewalks; two by Walheim and Schlegel and one by Walheim and Love.

The International Space Station's Expedition 16 Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Tani started their day at 4 a.m. CST. Today they will conduct a leak check of the Pressurized Mating Adapter 2 where Atlantis will dock to the station Saturday morning at 11:25 a.m. CST.

Commander Steve Frick and his crewmates, Pilot Alan Poindexter and Mission Specialists Leland Melvin, Rex Walheim, Stanley Love, Hans Schlegel and Leopold Eyharts, today completed a five-hour inspection of Atlantis' heat shield using the shuttle's robotic arm and the Orbiter Boom Sensor System. Imagery analysts and engineers on the ground will add today's three-dimensional sensor images to imagery and accelerometer data collected at launch and during the climb to orbit and continue their analysis of the shuttle's heat shield.

Also today, the crew checked out the tools that will be used during tomorrow's rendezvous and docking to the station, installed the centerline camera that will be used during docking and extended the outer ring of the Orbiter Docking System.

Spacewalkers Walheim, Schlegel and Love checked out the spacesuits that they will wear during the mission's three spacewalks. At 2:02 p.m. Walheim reported that the suits had been fully prepared for transfer to the space station.

On board the space station, Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Dan Tani readied the station for the arrival of Atlantis' crew by conducting a leak check of Pressurized Mating Adapter-2, Atlantis' docking point.

Tomorrow, Frick will perform the rendezvous pitch maneuver, an orbiter back-flip 600 feet below the space station that will allow Whitson and Malenchenko to take hundreds of detailed images of the orbiter's underside. With the pitch maneuver complete, Frick will fly the shuttle ahead of the station and slowly ease the orbiter back to a docking with the space station.

Tomorrow also marks Whitson's 48th birthday. She commented today that she was looking forward to Atlantis' arrival as her birthday present.

The STS-122 crew is on an 11-day mission that will deliver a new research module to the International Space Station, the European Space Agency's Columbus laboratory. Columbus will be Europe's largest contribution to the construction of the station, adding 2,648 cubic feet of pressurized volume, four science experiment racks and one storage rack to the orbiting complex.

Atlantis' crew is scheduled to go to sleep at 7:45 p.m. and will awaken at 3:45 a.m.

aturday = Docking Day. Happy Birthday, Peggy Whitson!

STS-122/Atlantis docked smoothly at the PMA-2 (Pressurized Mating Adapter-2) port at 12:17pm EST, eight minutes ahead of time, after successfully completing the RPM (R-Bar Pitch Maneuver) at 11:32am. The station now hosts ten occupants again as Mission 1E is underway. (The combined crew is comprised of ISS CDR Peggy Whitson, FE-1 Yuri Malenchenko, FE-2 Dan Tani, STS CDR Steve Frick, PLT Alan Poindexter, MS1 Leland Melvin, MS2 Rex Walheim, MS3 Hans Schlegel, MS4 Stanley Love, and MS5 LÃ(c)opold Eyharts who replaces Dan Tani as FE-2, while the latter returns on the Atlantis as MS-5.)

What wasn't delayed, however, was the official crew rotation of ESA Astronaut Leopold Eyharts and Expedition 16 Flight Engineer Dan Tani, which was completed at 5:20 p.m. Eyharts now is a member of Expedition 16 and Tani is an STS-122 mission specialist.

Expedition 16 Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Tani welcomed the seven-man Atlantis crew into the space station at 12:40 p.m., following an 11:17 a.m. docking, following a flawless rendezvous throughout the morning.

They'll have 24 extra hours to finish preparing for the mission's next major milestone, however, due to a crew medical issue. The mission's first spacewalk originally was scheduled for Sunday, but has been postponed until Monday. Mission Specialist Rex Walheim will be joined for the spacewalk by Mission Specialist Stanley Love, rather than Mission Specialist Hans Schlegel, as originally planned.

Space Shuttle Program Deputy Manager John Shannon said ground teams are currently reworking the mission timeline and there should be no impact to the completion of the mission's objectives, despite being shifted one day later.

To make up for the delay, Shannon said the crew will conserve enough power to spend an additional day in space. Atlantis went into orbit with the option of adding one day to its mission, which was to be used for additional work commissioning the new Columbus module. By adding a second day, the crew could shift their activities by one day and still have time for more Columbus work after the module is installed.

Before docking, Commander Steve Frick flew the shuttle through a backflip to allow the space station crew a good view of Atlantis' heat shield. Whitson and Malenchenko took about 300 photos of the shuttle's thermal protection system and sent them down to teams on the ground for analysis.

The teams also are paying close attention to photos sent down by the crew Friday of minor damage to a thermal blanket over the shuttle's right Orbital Maneuvering System pod. A similar condition occurred on the left pod last year on STS-117 and was repaired during a spacewalk.

Shannon said this case does not seem to be as much of a concern, because this particular blanket location does not experience as much heat during the shuttle's reentry.

Docking went smoothly with the exception of a hiccup with one of the station's five general purpose computers. After experiencing some problems with guidance and navigation software on the computer, the crew opted to use other computers for the shuttle's rendezvous with the station. Only one computer is needed to perform the rendezvous, with one computer required for backup. Mission Control will review the computer's software to ensure its health.

Space shuttle Atlantis will deliver the new module and a new crew member to the station when it docks at 11:25 a.m. CST to begin 6 days of docked operations.

Today's wakeup song, played for Commander Steve Frick, at 3:45 a.m. CST was the theme song from Garrison Keillor's radio variety show 'A Prairie Home Companion.' The song is the Spencer Williams composition "Tishomingo Blues," but with lyrics written especially for the show.

Frick and his shuttle crewmates begin rendezvous operations at 5:30 a.m. CST. At 10:23 a.m., at a range of 600 feet below the station, Frick will command Atlantis to perform a back flip so ISS Commander Peggy Whitson and Flight Engineer Yuri Malenchenko can photograph the thermal tiles on the shuttle's underside. Those digital images will be sent to Mission Control for analysis.

With the pitch maneuver complete, Frick will then fly the shuttle ahead of the station and slowly ease the orbiter back to a docking with the space station.

After hatch opening, the crew members will begin moving spacewalking equipment into the Quest airlock to prepare for the first excursion on Sunday. Mission Specialists Rex Walheim and Hans Schlegel will go outside to prepare the Columbus module to be grappled by the station's robotic arm, lifted from Atlantis' payload bay, and installed on the starboard side of Harmony.

The official exchange of Atlantis crewmember LÃ(c)opold Eyharts with space station Flight Engineer Dan Tani, who arrived at the station in October, is planned for 6 a.m. CST Sunday. The transfer becomes official with the installation of Eyharts' customized seat liner in the Soyuz.

The STS-122 crew is on an 11-day mission to install and activate Columbus. The new laboratory is Europe's largest contribution to the construction of the station, adding 2,648 cubic feet of pressurized volume, four science experiment racks and one storage rack to the orbiting complex.

Ahead: Week 17 of Increment 16.

Mission 1E replanning by MCC-Houston, driven by the one-day delay of the first spacewalk, was completed last night, as follows:

Approved mission extension by one day (i.e., 12+0+2 instead of 11+0+2), resulting in 2/19 (Tuesday) as return date for Atlantis;
Limiting resource being oxygen (O2), under further discussion is the option to either extend by one more docked day or transfer the unexpended O2 to the ISS (current O2 margins are estimated to be 11+1+2 plus an additional 20-25 hours. These are still being refined given the insertion of the new FD4);
All FD 4 activities moved to FD 5. EVA-1 will be conducted by Stanley Love and Rex Walheim tomorrow, with Campout of the two tonight;
Today (FD 4) was replanned and includes 1.5 hrs of focused inspection (FI) of the starboard OMS (Orbital Maneuvering System) pod blanket that has a corner slightly peeled back (the FI, starting at ~ 2:15 pm EST, is planned for 90 min, with additional FI time available on FD 06 if needed);
Transfer status: 22% of transfer complete, 6 hours of transfer scheduled for FD 4, expect 35/40 lbs N2 transfer today, 3 CWCs filled.
Wakeup time for the ISS crew remains at 4:45am EST, with sleep time tonight 8:45pm. Same times for the Shuttle crew.

Additional Details: ISS On-Orbit Status 02/10/08.

Mission 1E's EVA-1 was completed successfully by Stanley Love & Rex Walheim in 7hr 58min, accomplishing all its objectives.
(During the spacewalk, Walheim (EV1) & Love (EV2) prepared Columbus for unberthing and installation, hooking up electric cables, removing protective covers from the module's docking mechanism and equipping Columbus with the PDGF (Power & Data Grapple Fixture) required for grappling. They also started preparing the NTA (Nitrogen Tank Assembly) for removal, preparatory to replacement with a new NTA on EVA-2 (disconnecting electric cables and two ammonia flex hoses was deferred to Wednesday, but Walheim unfastened two of the four bolts holding down the NTA). Official start time of the spacewalk was 9:13am EST, about 25 minutes ahead of the timeline, and it ended at 5:11pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 58min. It was the 102nd spacewalk for ISS assembly & maintenance and the 74th from the station (28 from Shuttle, 52 from Quest, 22 from Pirs) totaling 451h 11min, and the 6th for Expedition 16 (totaling 43h 19min.) After today's EVA, a total of 125 spacewalkers (94 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 639h 33min outside the station on building, outfitting and servicing. It was also the 124th spacewalk by U.S. astronauts.)

Additional Details: ISS On-Orbit Status 02/11/08.

At ~9:15am EST, the European Columbus laboratory was opened and entered by crewmembers for the first time. (Columbus is permanently attached at the starboard port of Node-2.)

Crew sleep cycle remains at 4:45am - 8:15pm for both crews.

Before breakfast, FE-2 Dan Tani completed his daily access of the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink. (To monitor the crewmember's sleep/wake patterns and light exposure, Dan wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)

CDR Peggy Whitson and FE-2-16 Leo Eyharts continued their IMMUNO (Integrated Immune Assessment) experiment, begun on 2/9, with liquid saliva collections, first thing after wake-up and prior to breakfast, drinking and teeth-brushing. All samples were stored at ambient temperature. Dan Tani's IMMUNO liquid saliva collection starts tomorrow morning. (IMMUNO (Integrated Immune Assessment)is a 24-hr. test of human immune system changes, with the objective to investigate immune neuro-endocrine reactions in the space environment by studying samples of saliva, blood and urine using collection kits and the biomedical (MBI) protection kit, to develop and validate an immune monitoring strategy consistent with operational flight requirements and constraints. The strategy uses both long and short duration crewmembers as study subjects. The saliva is collected in two forms, dry and liquid. The dry samples are collected at intervals during the collection day using a specialized book that contains filter paper. The liquid saliva collections require that the crewmember soak a piece of cotton inside their mouth and place it in a salivette bag; there are four of the liquid collections during docked operations. The on-orbit blood samples are collected right before undocking and returned on the Shuttle so that analysis can occur with 48 hours of the sampling. This allows assays that quantify the function of different types white blood cells and other active components of the immune system. For cold storage, samples are secured in the MELFI (Minus-Eighty Laboratory Freezer for ISS). Also included are entries in a fluid/medications intact log, and a stress-test questionnaire to be filled out by the subject at begin and end. Urine is collected during a 24-hour period, conventionally divided into two twelve-hour phases: morning-evening and evening-morning.)

Crew sleep cycle remains at 4:45am EST - 8:15pm for both crews.

Mission 1E's EVA-2 was completed successfully by Rex Walheim & Hans Schlegel in 6h 45m, accomplishing all its objectives and get-aheads.
(During the spacewalk, Walheim (EV1) & Schlegel (EV2) removed the new NTA (Nitrogen Tank Assembly) from the Shuttle PLB (Payload Bay), 'flew' it to the CETA (Crew & Equipment Translation Aid) cart for transfer to the P1 truss, installed it in place of the failed NTA, which they returned via CETA for stowage in the PLB, and performed Get-Aheads, viz.: Clean up Lab MMOD (Micrometeoroid/Orbital Debris Shield) & install Columbus Trunnion Covers.) Official start time of the spacewalk was 9:27am EST, about 8 min ahead of the timeline, and it ended at 4:12pm. Total EVA duration (PET = Phase Elapsed Time) was 6h 45min. It was the 103rd spacewalk for ISS assembly & maintenance and the 75th from the station (28 from Shuttle, 53 from Quest, 22 from Pirs) totaling 457h 56min, and the 7th for Expedition 16 (totaling 50h 04min). After today's EVA, a total of 127 spacewalkers (95 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 646h 18min outside the station on building, outfitting and servicing. It was also the 125th spacewalk involving U.S. astronauts.)

Additional Details: ISS On-Orbit Status 02/13/08.

Crew sleep cycle shifted one hour earlier: 3:45am - 7:15pm for both crews.

Last night, Mission 1E was extended by one day (13+0+2), with landing now on Wednesday, 2/20, at ~9:03am EST (if at KSC).

Columbus final activation has been completed.

After yesterday's command queue lockup between the COL CCS (Columbus Orbital Laboratory Command & Control System) and the COL MMC (Mission Management Computer), final activation of COL data management systems was accomplished late last night by transitioning/swapping the primary & backup C&C MDM (Multiplexer/Demultiplexer) computers. (The MMC is the intermodule interface computer required between the US C&DH (Command & Data Handling) system and the COL DMC (Data Management Computer) which handles equipment monitoring)

This morning, Shuttle Commander Steve Frick and Mission Specialists Hans Schlegel and Daniel Tani, station Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Leopold Eyharts spoke with German Chancellor Angela Merkel. Also participating were European Space Agency Director General Jean-Jacques Dordain and former astronaut Thomas Reiter of the German Space Agency.

The astronauts then spoke with NBC News, WOI-TV and WBBM radio. WOI-TV is in Des Moines, Iowa, capital of Whitson's home state. WBBM is in Chicago, near Tani's hometown of Lombard, Ill.

Tonight, Mission Specialists Stanley Love and Rex Walheim will camp out inside the Quest airlock. This will purge the nitrogen from their bodies in advance of tomorrow's spacewalk.

During the 6.5-hour spacewalk that is scheduled to start at 7:40 a.m. CST, Love and Walheim will install two experiment platforms on the outside of the Columbus module. If time allows, they also will take a closer look at some damage to a handrail on the Quest airlock. The astronauts have built a special tool that will be used during the inspection, which comprises an overglove material wrapped around a socket. They will run the tool over the damaged handrail to see if there are any edges sharp enough to cut the material.

The shuttle crew woke up at 2:45 a.m. to 'Consider Yourself at Home.' The song, which is from the musical 'Oliver!', was played for Mission Specialist Stanley Love.

The first major event of the day will begin at 8:55 a.m., when shuttle Commander Steve Frick, Mission Specialists Hans Schlegel and Daniel Tani, station Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Leopold Eyharts speak with Angela Merkel, the Chancellor of Germany. Schlegel, a European Space Agency astronaut, is from Germany.

Tani, Whitson and Malenchenko will then speak with reporters from NBC News, WOI-TV and WBBM radio at 10:10 a.m. WOI-TV is in Des Moines, Iowa, capital of Whitson's home state. WBBM will be calling from Chicago, near Tani's hometown of Lombard, Ill.

Before the day is over, the crews will also go over the plan for the mission's third and final spacewalk. Love and Mission Specialist Rex Walheim will be installing experiment platforms on the outside of the new Columbus laboratory and storing a failed control moment gyroscope in the shuttle's cargo bay. They will also take a closer look at some damage to a handrail on the Quest Airlock that may be the cause of cuts to spacesuit gloves on recent missions.

Part of today's preparations will involve building a tool that will be used in the inspection. Astronauts will wrap an overglove around a socket, then run the tool over the damaged handrail to see if there are any edges sharp enough to cut the material.

ISS crew goes to sleep one hour earlier than yesterday: 3:45am - 6:15pm, Shuttle crew half an hour later. 3:45am - 6:45pm.

Mission 1E's EVA-3 was completed successfully by Rex Walheim & Stan Love in 7h 25m, accomplishing all its objectives and get-aheads.
(During the spacewalk, Walheim (EV1) & Love (EV3) transferred the European SOLAR (Solar Monitoring Observatory) and the EuTEF (European Technology Exposure Facility) to the COL EPF (Columbus Orbital Laboratory External Payload Facility), retrieved the failed CMG (Control Moment Gyro) for stowage in the Shuttle PLB for return, installed COL worksite interface fixtures and handrails, inspected a suspected sharp-edged MMOD impact site on an Airlock (A/L) handrail (#508), and inspected, photographed and took samples from the failed starboard SARJ (Solar Alpha Rotary Joint) race ring and covers not yet inspected before. Official start time of the spacewalk was 8:07am EST, about 28 min ahead of timeline, and it ended at 3:32pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 25min. It was the 104th spacewalk for ISS assembly & maintenance and the 76th from the station (28 from Shuttle, 54 from Quest, 22 from Pirs) totaling 465h 21min, and the 8th for Expedition 16 (totaling 57h 29min). After today's EVA, a total of 129 spacewalkers (97 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 653h 43min outside the station on building, outfitting and servicing. It was also the 126th spacewalk involving U.S. astronauts.)

Wake/sleep cycle shifted back again to prepare for 2/18 undocking: 3:15am - 5:15pm EST, Shuttle crew: 3:15am - 5:45pm.

More crewtime was applied to COL (Columbus Orbital Laboratory) rack configuration, activation & operation, led by CDR Peggy Whitson and FE-2-16 Leo Eyharts. (In particular, Whitson focused on readying the EDR (European Drawer Rack), gathering equipment, outfitting the rack, installing PCDF EU (Protein Crystalization Diagnostic Facility Electronic Unit) coolant water and data connections, setting up the laptop, verifying its software load & activating it, checking out the EDR RFI (Rack Fire Indicator), and checking out the functionalities of the rack's various subsystems.)

Additional Details: ISS On-Orbit Status 02/16/08.

Earlier in the day, space shuttle Atlantis' propulsion system was used to reboost the station's altitude by about 1.4 miles (2.2 kilometers) -the first reboost of the station using shuttle thrusters since 2002.

The altitude adjustment lasted 36 minutes and used four of the shuttle's vernier jets that produced about 28 pounds of thrust each to gently raise the orbit. The increased altitude will allow the station to be in the proper orbit for next month's arrival of Endeavour on the STS-123 mission.

Early Saturday, all 10 members of the shuttle and station crews held their traditional news conference with media in the United States and Europe. Today set the stage for the final transfer of cargo between the shuttle and station early on Sunday. The crews will bid farewell to one another and close the hatches between the shuttle and station shortly after 11 a.m. Sunday. Atlantis' departure remains scheduled for early Monday.

Dan Tani's 118th day in space (116 aboard ISS). Ahead: Week 18 of Increment 16.

Wake/sleep cycle shifted further back to prepare for 2/18 undocking: 1:45am - 4:15pm EST (incl. Eyharts), Shuttle crew: 1:45am - 4:45pm (incl. Tani).

CDR Peggy Whitson performed her final INTEGRATED IMMUNE blood collection, assisted by MS1 Leland Melvin, right before hatch closure. FE-2 Dan Tani will continue his saliva collections, both liquid and dry, and blood collections aboard the Atlantis all the way home FE-2-16 Leo Eyharts transferred his and Peggy's saliva return pouches and blood sleeves as well as Dan's saliva collection kit to the Shuttle for return. (Background: IMMUNE assessment, integrated with the Russian IMMUNO, is a 24-hr. test of human immune system changes, with the objective to investigate immune neuro-endocrine reactions in the space environment by studying samples of saliva, blood and urine using collection kits and the biomedical (MBI) protection kit, to develop and validate an immune monitoring strategy consistent with operational flight requirements and constraints.

US Holiday (President's Day).

STS-122/Atlantis and ISS are flying in separate orbits again (Flight Day 12 for STS-122/1E)

After final preparations on both sides of the hatches (closed yesterday on ISS side at 1:03pm EST), Atlantis this morning undocked smoothly at 4:27am from PMA-2 (Pressurized Mating Adapter 2), after a total docked time of 11d 13h 42m. (For undocking, the station was turned from -XVV through ~180 deg to +XVV ZLV (+x-axis in velocity vector, z-axis in local vertical) at ~3:30am, put briefly on free drift for the undocking, and then maneuvered to 1E Stage attitude of +XVV TEA attitude at 5:06am.) See picture from Atlantis flight deck, below.

Additional Details: ISS On-Orbit Status 02/18/08.

Wake/sleep cycle for the crew was adjusted to 1:00am-4:30pm EST.

For today's Voluntary Science program, CDR Whitson continued her work with the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment in the MSG (Microgravity Science Glovebox), conducting runs #28, #29 and #30, investigating low frequency behavior of the lowest concentration magnetorheological (MR) fluid, exchanging video tapes after each run, then switching to the highest concentration (vial #4) and finally powering the MSG down. (The activity included an EPO (Education Payload Operation) Demo for grades 9-12. InSPACE obtains basic data on MR fluids, i.e., a new class of "smart materials" that can be used to improve or develop new brake systems, seat suspensions robotics, clutches, airplane landing gear, and vibration damper systems. The colloidal (dispersed) particles are contained in CAs (Coil Assemblies) in the MSG that subject them to electric fields at certain strength and frequencies. The desired strong dipolar interaction between the small colloidal particles can be achieved in micro-G simply with an external magnetic field being turned on and off. On the ground, the flow properties (rheology) of many materials, especially those making up consumer products like detergents, fabric softeners, toothpaste and paints, are similarly controlled, though not by magnetic fields but by adding a polymer. It now appears, for example, that new formulations of fabric softeners may perform better in space than on earth. )

STS-122/Atlantis returned to Earth this morning after 12d 18h 22min in space, touching down at KSC on the first landing opportunity at 9:07am EST, after 202 orbits & 5.3 million miles. During the perfectly executed ISS 1E mission, its seven-member crew conducted three EVAs, delivered and installed the European Columbus laboratory, brought up new Expedition 16 crewmember LÃ(c)opold Eyharts and returned his predecessor Dan Tani who spent 121 days in space (116 on board the station). It was the 121st flight of a Space Shuttle, the 24th Shuttle mission to visit the station and the 29th for Atlantis. Welcome back, Atlantis! Next up: STS-123/Endeavour/1J/A on March 11 with the Kibo laboratory module - Japan/JAXA's BIG day.

The regen process will be terminated before sleeptime, at ~2:15pm EST. Regeneration of bed #2 follows tomorrow. (Regeneration of each of the two cartridges takes about 12 hours and is conducted only during crew awake periods.)

CDR Whitson and FE-2 Eyharts completed the mandatory 30-min. medical CBT (Computer-based Training) contingency drill, with video & text material, to refresh their CMO (Crew Medical Officer) proficiency/rating. (To maintain proficiency in using HMS (health maintenance systems) hardware, today's training focused on Part 2 of the regular exercise, viz., a review of Nasal Airway, Suction Device, ILMA (Intubating Laryngeal Mask Airway) with endotracheal tube, and Cricothyrotomy (incision to re-enable breathing air inflow).)

The crew performed the regular weekly three-hour task of thorough station cleaning. ("Uborka", usually done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the Service Module (SM) dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the CDR's sleep station with a standard cleaning solution; also, fan screens and grilles are cleaned to avoid temperature rises. Special cleaning is also done every 90 days on the HEPA (high-efficiency particulate air) bacteria filters in the Lab.)

Underway: Week 19 of Increment 16.

Before breakfast, having reached the FD15 (Flight Day 15) mark in his flight, FE-2 Eyharts undertook his first session with the NASA/JSC experiment NUTRITION w/Repository, today limited to two blood draws (for Serum & Heparin). (Acting as operator and CMO (Crew Medical Officer), Peggy Whitson performed phlebotomy on Leo, i.e., drew blood samples (from an arm vein) which were first allowed to coagulate in the Repository, then spun in the HRF RC (Human Research Facility/Refrigerated Centrifuge) and finally placed in MELFI (Minus-Eighty Laboratory Freezer for ISS). The RC was later powered off after a temperature reset to limit wear on the compressor, and cleaned. Background: NUTRITION is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight; this includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes. The Clinical Nutritional Assessment profile currently required on all U.S. Astronauts collects blood and urine samples preflight and postflight. NUTRITION expands this protocol by also capturing inflight samples and an additional postflight sample. Furthermore, additional measurements are included for samples from all sessions, including additional markers of bone metabolism, vitamin status, and hormone and oxidative stressor tests. The results will be used to better understand the impact of countermeasures (exercise and pharmaceuticals) on nutritional status and nutrient requirements. The Clinical Nutritional Assessment profile (MR016L), first started on two Mir crewmembers and then on all ISS US crews, nominally consists of two pre-flight and one post-flight analysis of nutritional status, as well as an in-flight assessment of dietary intake using the FFQ (Food Frequency Questionnaire). The current NUTRITION project expands MR016L testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

The samples were consecutively stored in the MELFI (Minus-Eighty Laboratory Freezer for ISS). Blood collections were performed by Peggy on Leo yesterday. (The current NUTRITION/Repository project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

Additional Details: ISS On-Orbit Status 02/26/08.

The sampling kit was then stowed away. Leo's next NUTRITION/Repository activity will be his Flight Day 30 (FD30) session. (The current NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight.

Progress thrusters (DPO) were inhibited and not involved. (Crew activities focused on TORU activation, inputting commands via the RUO Rotational Hand Controller and close-out ops. TORU lets an SM-based crewmember perform the approach and docking of automated Progress vehicles in case of failure of the automated KURS system. Receiving a video image of the approaching ISS, as seen from a Progress-mounted docking television camera ('Klest'), on a color monitor ('Simvol-Ts', i.e. 'symbol center') which also displays an overlay of rendezvous data from the onboard digital computer, the crewmember steers the Progress to mechanical contact by means of two hand controllers, one for rotation (RUO), the other for translation (RUD), on adjustable armrests. The controller-generated commands are transmitted from the SM's TORU control panel to the Progress via VHF radio. In addition to the Simvol-Ts color monitor, range, range rate (approach velocity) and relative angular position data are displayed on the 'Klest-M' video monitor (VKU) which starts picking up signals from Progress when it is still approximately 7 km away. TORU is monitored in real time from TsUP over Russian ground sites (RGS) and via Ku-band from Houston, but its control cannot be taken over from the ground.)

Before breakfast and exercise, FE-2 Eyharts performed his first PHS (Periodic Health Status) w/Blood Labs examination. CDR Whitson assisted in drawing blood and using the U.S. PCBA(Portable Clinical Blood Analyzer). The second part of PHS, Subjective Clinical Evaluation, was performed later in the day. (The PHS exam, with PCBA analysis and clinical evaluation, is guided by special software (IFEP, In-Flight Examination Program) on the MEC (Medical Equipment Computer). While PCBA analyzes total blood composition, the blood's hematocrit is particularly measured by the Russian MO-10 protocol.)

The crew completed the regular weekly three-hour task of thorough station cleaning. ("Uborka", usually done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the Service Module (SM) dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the CDR's sleep station with a standard cleaning solution; also, fan screens and grilles are cleaned to avoid temperature rises. Special cleaning is also done every 90 days on the HEPA (high-efficiency particulate air) bacteria filters in the Lab.)

Ahead: Week 20 of Increment 16.

For today's Voluntary Science program, Peggy Whitson continued her work with the InSPACE-2 (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions) experiment in the MSG (Microgravity Science Glovebox), conducting another three runs (#38, #39 and #40) to investigate higher-frequency behavior (2 Hz for #38 & #39, 5Hz for #40) at different current levels for the MR (magnetorheological) fluid with no vial change, exchanging video tapes after each run, then removing the vial assembly and finally powering the MSG down. (InSPACE obtains basic data on MR fluids, i.e., a new class of "smart materials" that can be used to improve or develop new brake systems, seat suspensions robotics, clutches, airplane landing gear, and vibration damper systems. The colloidal (dispersed) particles are contained in CAs (Coil Assemblies) in the MSG that subject them to electric fields at certain strength and frequencies. The desired strong dipolar interaction between the small colloidal particles can be achieved in micro-G simply with an external magnetic field being turned on and off. On the ground, the flow properties (rheology) of many materials, especially those making up consumer products like detergents, fabric softeners, toothpaste and paints, are similarly controlled, though not by magnetic fields but by adding a polymer. It now appears, for example, that new formulations of fabric softeners may perform better in space than on earth.)

FE-1 Malenchenko completed the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM), including ASU toilet facilities systems/replaceables plus the weekly collection of the toilet flush counter (SPK-U) and water supply (SVO) readings for calldown to TsUP/Moscow. (Regular daily SOZh maintenance consists of replacement of the KTO & KBO solid waste containers, replacement of an EDV-SV waste water and EDV-U urine container, replacement of the KOV EDV for the Elektron-intended water, and processing U.S. condensate water as it becomes available in a filled CWC (Contingency Water Container) from the Lab humidifier. Weekly SOZh reports (on Sundays) to TsUP/Moscow deal with number & dates of water and urine containers, counter readings of water consumption & urine collection, plus data and total operating time of the Russian POTOK-150MK (150 micron) air filter unit of the SOGS air revitalization subsystem.)

After Houston flight controllers deactivated the CDRA (Carbon Dioxide Removal Assembly) early this morning (4:00am-9:00am EST) and cooling was no longer required, CDR Whitson disconnected the ITCS LTL QD (Internal Thermal Control System/Low Temperature Loop/Quick Disconnect) jumper to the CDRA rack (LAB1D6).

Working from the Russian voluntary 'time permitting' task list, Yuri Malenchenko -

Completed his eighth run of the Russian DZZ-2 "Diatomeya" ocean observations program (using the NIKON F-5 digital still camera with 80-200 mm lens and the SONY PD-150P camcorder at medium zoom Yuri focused on phytoplankton field blooming in early March in the sub-arctic front of the Atlantic and bioproductive processes intensifying at this time of year in the Indian Ocean due to restructuring of the monsoon circulation; also of interest were associated oceanic phenomena (cloud pattern, water surface dynamics) in the target areas, today in the Indian Ocean were the Oman coastal area and the areas west of Australia, and in the Atlantic Ocean the Gulf of Saint Lawrence and the Western Sahara offshore area);
Conducted the regular daily checkup on the Japanese experiment GCF-JAXA (Granada Crystallization Facility) in the Russian TBU incubator, maintained at +20 degC, including a temperature check on its ART (automatic temperature recorder), and
Performed the daily monitoring, picture-taking and downloading for the BIO-5 Rasteniya-2 ("Plants-2") experiment which researches growth and development of plants (peas) under spaceflight conditions in the Lada-12 greenhouse from IBMP (Institute of Bio-Medical Problems, Russian: IMBP).
At ~3:45am, the FE-1 participated in today's Presidential Election in the Russian Federation with a personal downlink at ~3:45am EST as a Crew Choice event via RGS (Russian Ground Site) VHF.

Eyharts and Whitson had their weekly PFCs (Private Family Conferences) via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on the SSC-10 laptop), Leo at ~10:45am EST, Peggy at ~12:12pm

The crewmembers completed their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (FE-2), TVIS treadmill (CDR, FE-1, FE-2), RED resistive exercise device (CDR) and VELO bike with bungee cord load trainer (FE-1, FE-2).

No CEO photo targets uplinked for today.

FE-1 Malenchenko updated software on the Russian RS1 laptop HDD (Hard Disk Drive). (After first connecting the A31p to the AGAT external monitor (temporarily disconnected from TP2 laptop), the FE-1 'ghosted' (cloned) its HDD with Vers. 07.05 file structure from a DVD, then updated the RS1 HDD new software from an USB memory stick, and created a copy of the load.)

Afterwards, Malenchenko conducted the periodic/long-term inspection of the pressure hull in the Service Module Working Compartment (SM RO), looking for any moisture, deposits, mold, corrosion and pitting behind panels 107, 109, 130, 134, 135, 138, 139, 452, also underneath the TVIS treadmill (where deposit was discovered earlier) and the cold plates (where SNT and STR lines are installed). (The inspection of the hull surface, which is coated with a primer and dark-green enamel, is done using cleaning napkins to wipe the area in question if required and reporting results to the ground. The hull inspection looks for changed color and cavities; if cavities are found, they are to be measured for depth after cleaning. Digital photographs of the shell before and after the removal of deposits will be made for documentation.)

(Today's troubleshooting dealt with repair and cleaning of a threaded hole on a standoff element for the right K-BAR capture fitting. The FE-2 used a vacuum cleaner to remove FOD (Foreign Object Debris) plus safety goggles, rubber gloves and a surgical mask for his protection.)

Leo also continued COL commissioning, today unlocking (but not completely removing) the AVM (Anti-Vibration Mount) locking bolts of the module's ISFA (Intermodular Ventilation Supply Fan Assembly) and IRFA (Intermodular Ventilation Return Fan Assembly). (The two fan assemblies are located at opposite sidewalls of the module, both behind cover panels.)

CDR Whitson performed the periodic calibration of the two CSA-O2 (Compound Specific Analyzer-Oxygen sensor) instruments #1041 & #1052, using a calibration tank with accurately known pressure. (Partial Pressure Oxygen (ppO2) readings were 21.4% before and 21.3% after calibration on #1041, 23,3%/21.3% on #1052.)

Afterwards, Whitson took the periodic CO2 (Carbon Dioxide) measurements in the cabin atmosphere with the CDMK (CO2 Monitoring Kit, #1013). (Measured levels were 0.45% in the Lab, 0.43% in the SM (Service Module), 0.44% in the COL (Columbus Orbital Laboratory). 0.45% = 4,500 ppm (parts per million).)

(SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

>>>Tonight's BIG EVENT: Launch of ATV Jules Verne (see Ascent Timeline below).

For his second run with the NASA/JSC experiment NUTRITION w/Repository, FE-2 Eyharts completed the all-day session, collecting urine samples for 24 hrs (to continue through tomorrow morning) and blood samples (for Serum & Heparin). (Acting as operator and CMO (Crew Medical Officer), Peggy Whitson performed phlebotomy on Leo, i.e., drew blood samples (from an arm vein) which were first allowed to coagulate in the Repository, then spun in the HRF2 RC (Human Research Facility 2/Refrigerated Centrifuge) and finally placed in MELFI (Minus-Eighty Laboratory Freezer for ISS).

After a flawless, precise on-time launch last night at 11:03:04 pm EST at Kourou/French Guiana, ATV1 Jules Verne is on its way to the ISS. (Currently entering a period of test and orbit raising maneuvers, the European automated freighter will start 'loitering' on 3/19 about 1200 miles ahead of ISS (which at that time is busy with STS-123/1J/A), then will begin maneuvering at 3/27, conduct checkout Demos toward an IMMT Go/No Go decision on 4/2, and Docking on 4/3 (start Final Approach: ~6:10am EDT, contact SM aft port: ~10:20am.)

STS-123/Endeavour (ISS-1J/A) lifted off spectacularly in darkness early this morning right on time (2:28am EDT) with all systems performing nominally, for rendezvous with ISS tomorrow (3/12, Wednesday) and docking at approximately 11:25pm EDT. The Orbiter is carrying the seven-member crew of Commander Dominic L. Gorie, Pilot Gregory H. Johnson and Mission Specialists Richard M. Linnehan, Robert L. Behnken, Michael J. Foreman, Takao Doi and Garrett E. Reisman. Reisman will replace LÃ(c)opold Eyharts as ISS Flight Engineer 2, who returns on 3/26 (nominal) with STS-123. STS-123 is the 122nd space shuttle flight, the 21st flight for Endeavour, the 25th flight to the station and the second of six Shuttle flights planned for 2008 (including the Hubble Service Mission 4). Its primary payloads are the 18,490-lbs Japanese Experiment Logistics Module-Pressurized Section (ELM-PS or JLP) and the 3,400-lbs Canadian Special Purpose Dexterous Manipulator (SPDM) 'Dextre'. We are off to another great mission!

Additional Details: ISS On-Orbit Status 03/11/08.

Aboard the shuttle are Commander Dominic Gorie, Pilot Gregory H. Johnson and Mission Specialists Robert Behnken, Mike Foreman, Rick Linnehan, Garrett Reisman and Takao Doi, a Japan Aerospace Exploration Agency astronaut.

Endeavour will deliver the first component of the Japanese laboratory complex, Kibo, to the station. Kibo, which means "Hope" in English, is the major contribution of Japan to the International Space Station. The laboratory complex will take three shuttle flights to assemble. Endeavour also is carrying an intricate robotics system called Dextre that was developed for the station by the Canadian Space Agency. The two-armed robot will be attached to the end of the station's robotic arm to handle smaller tasks that otherwise would require a spacewalk to accomplish.

The STS-123 mission will be the longest mission to date to the station and will include five spacewalks.

International Space Station Expedition 16 Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Leopold Eyharts were awake beginning their workday when Endeavour launched. Reisman will become a member of the station crew after docking as he trades places with Eyharts, who will return to Earth aboard Endeavour once it departs the station.

Endeavour's crew will begin a sleep period at 7:28 a.m. today and awaken at 3:28 p.m. to begin its first full day in space. The shuttle is scheduled to dock to the station at 10:20 p.m. Wednesday.

The crew was awakened at 3:28 p.m. by the Vince Guaraldi Trio's 'Linus & Lucy.' The song, which is from the album 'A Charlie Brown Christmas,' was played for Mission Specialist Mike Foreman.

The main activity of the day is the standard inspection of Endeavour's heat shield to ensure it is in good condition following launch. Commander Dominic Gorie, Pilot Gregory H. Johnson and Mission Specialist Takao Doi will use the shuttle's robotic arm and orbiter boom sensor system to scan the shuttle's wing leading edges and nose cap. The survey results will be sent to the ground for analysis.

Mission Specialists Robert L. Behnken, Rick Linnehan and Garrett Reisman will check out spacesuits in preparation for the five spacewalks they and Foreman will perform while at the International Space Station. Foreman has several other activities scheduled for the day, including preparations for Wednesday's docking with the station.

The station crew also is preparing for Wednesday's docking. Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Leopold Eyharts started their day at 3 p.m., after a shortened sleep period that allowed them to align their schedules with that of the shuttle crew.

STS-123/Endeavour continues its chaser flight for tonight's docking at ~11:25pm EDT, to begin ISS Stage 1J/A. (Catch-up rate ~480 nmi. per revolution of ~92 min). (Hatch opening is expected at ~1:08am, followed by: Safety Briefing, Soyuz seat liner transfer (for the Eyharts/Reisman exchange), SRMS (Shuttle Remote Manipulator System)- transfer of SLP-D1 (Spacelab Pallet Deployable 1), carrying SPDM 'Dextre', from Shuttle cargo bay to POA (Payload ORU Attachment) on MBS (Mobile Base System) at ~2:30am, and preparations for the first spacewalk, EVA-1, to be conducted by EV1 Linnehan & EV2 Reisman on 3/13 (~9:23pm EDT), preceded by their 'overnight' Campout tomorrow (6:43am-7:45pm) in the Airlock (A/L) for denitrogenation/pre-breathe. Main objectives of the nominal 16-day mission: Installation of the 18,490-lbs ELM-PS or JLP (Japanese Experiment Logistics Module-Pressurized Section) and the 3,400-lbs Canadian SPDM (Special Purpose Dexterous Manipulator) 'Dextre', delivering new ISS-16 crewmember Garrett Reisman & bringing LÃ(c)opold Eyharts back home, and conducting a total of five EVAs. Landing will nominally take place at KSC on FD17 (3/26) at ~8:35pm EDT.)

Additional Details: ISS On-Orbit Status 03/12/08.

Commander Dom Gorie and his crewmates, Pilot Greg Johnson and Mission Specialists Bob Behnken, Mike Foreman, Takao Doi, Rick Linnehan and Garrett Reisman, early Wednesday completed a five-hour inspection of Endeavour's heat shield using the shuttle's robotic arm and the Orbiter Boom Sensor System. Imagery analysts and engineers on the ground will add these sensor images to those collected at launch and during the climb to orbit and continue their analysis of the orbiter's heat shield.

Additionally the STS-123 crew checked out the tools that will be used during Wednesday's rendezvous and docking to the station; installed the centerline camera that will be used during docking; and extended the outer ring of the Orbiter Docking System.

Spacewalkers Linnehan, Foreman, Behnken and Reisman checked the spacesuits that they will wear during the mission's five planned spacewalks.

On board the space station, Commander Peggy Whitson and Flight Engineers Yuri Malenchenko and Leopold Eyharts readied the station for the arrival of Endeavour by conducting a leak check of the docking port attached to the Harmony node.

About an hour before docking as the shuttle approaches the station, Gorie will perform the rendezvous pitch maneuver -an orbiter back-flip -600 feet below the station that will allow Whitson and Malenchenko to take hundreds of detailed images of the orbiter's underside. With the pitch maneuver complete, Gorie will fly the shuttle to a point about 300 feet in front of the station and then slowly ease the orbiter back to a docking.

STS-123 is budgeted for 16 days -the longest mission to the station -and will deliver the Japanese logistics compartment and the Canadian dextrous robot arm to their permanent home. A record five spacewalks will be performed while Endeavour is docked to the station to assist with the robotic attachment of the small logistics module and the assembly of Dextre -the Special Purpose Dextrous Manipulator that will extend the reach and capability of the station's robotic arm.

Endeavour's crew is scheduled to go to sleep at about 7 a.m. with the wakeup call from Mission Control scheduled for 2:58 Wednesday afternoon.

STS-123/Endeavour docked smoothly last night at 11:49pm EDT at the PMA-2 (Pressurized Mating Adapter-2) port, 24 minutes behind schedule (due to loss of target lock by the CW {Continuous Wave} laser of the Shuttle's TCS {Trajectory Control Sensor} during the manual rendezvous phase, requiring manual lock re-acquisition). The RPM (R-Bar Pitch Maneuver) started at 10:26pm and was successfully completed at 10:34pm, with Whitson and Malenchenko taking 200-300 close-up photographs of Endeavour's bottom heatshield. The station now hosts ten occupants again as Mission 1J/A is underway. (At the point of docking, Peggy Whitson rang the traditional ship's bell and announced 'Endeavour landed!' The combined crew is comprised of ISS CDR Whitson, FE-1 Yuri Malenchenko, FE-2 LÃ(c)opold Eyharts, STS CDR Dominic Gorie, PLT Gregory Johnson, MS1 Robert Behnken, MS2 Mike Foreman, MS3 Takao Doi (Japan), MS4 Rick Linnehan, and MS5/FE-2-16 Garrett Reisman who replaces Eyharts as FE-2, as the latter returns on the Endeavour as MS-5.)

Additional Details: ISS On-Orbit Status 03/13/08.

Shuttle Commander Dom Gorie started the approach with the Terminal Initiation burn earlier Wednesday evening leading to the Rendezvous Pitch Maneuver at 9:26 p.m. From a distance of 600 feet below the station, Gorie manually flew the shuttle through a well-timed backflip allowing the station crew to photograph the shuttle's heat shield. The photos are being analyzed by engineers in Mission Control to ensure the heat shield is in good condition.

Following docking and leak checks, the hatches between the two spacecraft were opened at 12:36 a.m. Thursday.

Expedition 16 Commander Peggy Whitson, joined by Flight Engineers Yuri Malenchenko and Leopold Eyharts, welcomed the shuttle crew onboard and provided an orientation of station operations and safety before proceeding to the remaining tasks.

The first 'transfer' item after hatch opening was swapping Mission Specialist Garrett Reisman for Expedition 16 Flight Engineer Eyharts from the European Space Agency.

The transfer was official when the form-fitting Soyuz seatliners were swapped at 2:50 a.m. Eyharts officially spent 33 days as a member of Expedition 16. With an on-time landing March 26, Eyharts will have spent 48 days in space.

The crew also prepared for the mission's first spacewalk, set to begin Thursday evening by Mission Specialist Rick Linnehan and Expedition 16 Flight Engineer Reisman.

Linnehan and Reisman transferred spacesuits to the station, and will spend the night in the Quest Airlock as part of the routine "campout" prebreathe protocol. The spacewalk will take about 6.5 hours as they plan to prepare the Japanese Experiment Logistics Module-Pressurized Section for unberthing from the payload bay. They also will work on some of the initial outfitting and assembly of the Special Purpose Dextrous Manipulator's two arms.

In preparation for that task, using the Canadarm2, Pilot Gregory Johnson and Mission Specialist Robert Behnken unberthed the Spacelab Pallet containing the Dextre and mated it to a temporary location on the station's Mobile Base System.

Mission Specialists Mike Foreman and Takao Doi commenced with the initial transfer work that will continue throughout the docked phase and set up photo and TV equipment between the two vehicles. The crews are scheduled to go to bed about 7 a.m. and wake up at 3:28 p.m.

Crew sleep cycle today:sleep 8:00am-4:30pm; wake 4:30pm-7:00am tomorrow.

Mission 1J./A's EVA-1 was completed successfully by Rick Linnehan & Garrett Reisman in 7h 1m, accomplishing all its objectives (no get-aheads).
(During the spacewalk, Linnehan (EV1) & Reisman (EV2) -

Prepared the JAXA JLP (JEM Experiment Logistics Module Pressurized Section) for its transfer, i.e. -
opened and secured the protective flap over the Node-2 topside (zenith) hatch viewport for the internal CBCS (Centerline Berthing Camera System),
removed 8 PCBM (Passive Common Berthing Mechanism) contamination protection covers,
demated & stowed JLP LTA (Launch-to-Activation) connectors & installed protective caps on the LTA receptacles;
Performed Part 1 Assembly of the SPDM (Special Purpose Dexterous Manipulator), i.e. -
released two OTCMs (ORU Tool Changeout Mechanisms) from the launch locations on the SLP (Spacelab Pallet),
installed the OTCMs on the SPDM,
released the OTP EDFs (ORU Temporary Platform Expandable Diameter Fasteners),
inspected the SLP PDGF (Power & Data Grapple Fixture) horseshoe connectors;
Took photographs of the SPDM, and
Installed a protective wire tie over the sharp edge divot discovered during Flight 1A on the Airlock (A/L) handrail.
Official start time of the spacewalk was 9:18pm EDT, about 5 min ahead of timeline, and it ended at 4:19am. Total EVA duration (PET = Phase Elapsed Time) was 7h 1min. It was the 105th spacewalk for ISS assembly & maintenance and the 77th from the station (55 from Quest, 22 from Pirs, 28 from Shuttle) totaling 472h 22min, and the 9th for Expedition 16 (totaling 64h 30min) and the 6th so far this year. After today's EVA, a total of 131 spacewalkers (99 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 660h 44min outside the station on building, outfitting and servicing. It was also the 127th spacewalk involving U.S. astronauts.)

Additional Details: ISS On-Orbit Status 03/14/08.

The astronauts started their day at 3:35 p.m. to the tune of The Byrds' 'Turn! Turn! Turn! (To Everything There is a Season).' The song was played for Mission Specialist Rick Linnehan.

Linnehan will be one of the first three crew members to enter the station's new module, the Japanese Experiment Logistics Module, Pressurized Section -or JLP, for short. Preceding him will be Japanese Space Agency astronaut Takao Doi and station Commander Peggy Whitson. That entry is scheduled to take place at 11:18 p.m.

But before that can happen, Doi, Linnehan and Whitson will spend several hours outfitting the vestibule between the station and the module and beginning activation of the module.

Work will also be done on Endeavour's other main cargo, the Special Purpose Dexterous Manipulator. When Dextre, as the robot is known, was removed from the shuttle's cargo bay after the shuttle docked to the station, ground teams ran into problems routing power to the pallet on which the robot is being assembled. The teams tried troubleshooting the problem with a software patch early this morning, but were not successful.

The next round of troubleshooting is scheduled to start at 8:53 p.m. In hopes of showing that the problem is in the pallet, not the robot itself, Mission Specialists Bob Behnken and Leopold Eyharts will grapple Dextre with the space station's robotic arm, Canadarm2, and attempt to power the robot through the robotic arm.

Shuttle Commander Dominic Gorie, Pilot Gregory H. Johnson and station Flight Engineer Garrett Reisman will take about 20 minutes out of their schedule at 12:28 a.m., to talk with reporters from ABC News, Space.com and Florida Today.

The astronauts will wrap up the fifth day of their mission by reviewing procedures for the mission's second spacewalk. Spacewalkers Linnehan and Mission Specialist Mike Foreman will spend their sleep period in the station's Quest Airlock in preparation for that spacewalk on Saturday.

f the Japan Aerospace Exploration Agency's Kibo laboratory, was installed on the station early Friday morning.

With Japan Aerospace Exploration Agency astronaut Takao Doi at the controls and assisted by Commander Dominic Gorie, the JLP was gently attached to its interim location on the Harmony Node 2 module at 3:06 a.m. CDT. The module, which primarily will be used for storage space atop the larger Kibo Laboratory, will be relocated to its permanent location after the arrival of Kibo on space shuttle Discovery's STS-124 mission in May.

Preparations for the move were among the tasks accomplished in today's spacewalk, the first of five planned for the mission. Mission Specialist Rick Linnehan and Expedition 16 Flight Engineer Garrett Reisman ventured out of the pressurized confines of the station at 8:18 p.m. to begin the 7-hour, 1-minute spacewalk, which ended at 3:19 a.m.

Once outside the Quest Airlock, they first removed a thermal cover to reveal the Centerline Berthing Camera System on top of the Harmony module. The system provides live video to assist with docking spacecraft and modules together and was used for the attachment of the Japanese Logistics Module - Pressurized Section.

Once in the shuttle's payload bay, the two spacewalkers removed contamination covers from the JLP docking mechanism. They also disconnected other power and heater connections, preparing it for its removal.

Next, the two headed to the port truss segment where they worked on the initial assembly of the Special Purpose Dexterous Manipulator, known as 'Dextre.' They installed both the Orbital Replacement Unit/Tool Changeout Mechanisms (OTCMs) -the 'hands' of Dextre's arms. The OTCMs are parallel jaws that can hold a payload or tool. They each also have a retractable motorized socket wrench to turn bolts and mate or detach mechanisms, as well as a camera and lights.

Initial attempts to route power to Dextre were not successful Thursday after its unassembled components were temporarily parked on the station's truss in a pallet structure. Canadian Space Agency engineers spent the day developing a software patch to bypass what was initially believed to be a problem in a communications path from the station's robotic workstation to the new device.

But Pierre Jean, CSA's acting ISS program manager, told a Friday morning briefing that a problem with a cable harness on Dextre's pallet housing, and not the robot itself, might be the cause for the initial power glitch. Jean said the grapple of Dextre by the station's Canadarm2 robotic arm later today should initiate the routing of power to Dextre to set the stage for the rest of its assembly over the next few days.

Pilot Greg Johnson also supported the spacewalk activity, overseeing the video operations and Mission Specialist Mike Foreman served as the intravehicular officer, assisting with the choreography of the spacewalks.

Meanwhile, Expedition 16 Commander Peggy Whitson assisted with the pre- and post-spacewalk activities, while Flight Engineer Yuri Malenchenko worked in the Russian segment.

Friday's spacewalk marks the 105th devoted to assembly and maintenance of the station with a total cumulative time of 660 hours. The second spacewalk is scheduled for Saturday night.

Crew sleep cycle today: Sleep 7:00am -3:30pm; wake 3:30pm -7:00am tomorrow.

Node-2/JLP vestibule outfitting, JLP ingress & JLP rack reconfigurations successfully accomplished! The first Japan-made human-rated space facility is now in operation. Arigato Gozaimasu!
(After completing outfitting the Node-2 vestibule to the JAXA JLP (JEM Experiment Logistics Module Pressurized Section), including removing CBM (Common Berthing Mechanism) hardware, installing several utility jumpers & taking air samples, crewmembers, led by 'high-productivity' Peggy Whitson, ingressed the module three hours early (~9:20pm EDT). This allowed the reconfiguring of three JLP racks (including relocating rack front stowage to Node-2 in preparation for the racks transfer to the JEM during Flight 1J, plus retrieving two bags from behind a rack that contain K-Bars and pivot fittings) to be completed right away, rather than tonight (FD6) as planned. FD6 timeline replanning includes troubleshooting/repair of the broken ISS Multimeter.)

More good news!

SPDM Dextre was checked out and is working nominally with both arms. (The waist-up-only robot from Canada arrived in space in nine separate pieces that are being assembled in the current spacewalks. Each of the two arms has seven joints; in addition, SPDM (Special Purpose Dexterous Manipulator) Dextre can pivot at the 'waist'. Its grippers (hands) have built-in socket wrenches, cameras & lights. Only one arm is movable at a time, to keep the robot stable and avoid a two-arm collision. Dextre can be attached to MT (Mobile Transporter) to translate along the stations rail tracks, or alternately to the SSRMS (Space Station Remote Manipulator System) to swing to places where the railcart can't go. What a supercool helper!)

The crew members were awakened at 2:43 p.m. with 'God of Wonders' by Caedmon's Call. The song was played for Endeavour's commander, Dominic Gorie.

Just before the crew went to sleep Sunday morning, flight controllers on the ground began checking out systems on Dextre -the Canadian Space Agency's Special Purpose Dexterous Manipulator. Those tests wrapped up at 6:18 a.m., and were all successful.

Mission Specialist Robert L. Behnken and station Flight Engineer Garrett Reisman will pick up where the ground teams left off. Behnken will go through a series of tests to make sure the brakes on the joints on the two 11-foot arms on the robot work. At 10:48 p.m., Behnken will stow Dextre in the configuration needed for the third spacewalk of the mission by him and Rick Linnehan Monday night, when the assembly of Dextre will be completed.

Behnken and Linnehan will be starting their campout in the Quest Airlock for that spacewalk at 3:43 a.m., but before they do that, they'll join Mission Specialists Mike Foreman, Reisman and station Commander Peggy Whitson for a set of interviews with reporters on the ground. KMOX Radio in St. Louis, WEWS-TV in Cleveland and WBZ-TV in Boston will be talking with the astronauts at 9:18 p.m. All three stations are all in cities close to crew members' hometowns: Behnken, Linnehan and Foreman are from Missouri, Massachusetts and Ohio, respectively.

Work inside the Japanese Experiment Logistics Module, Pressurized Section, continues to be ahead of schedule. Japan Aerospace Exploration Agency astronaut Takao Doi will be doing get-ahead tasks today for the STS-124 mission, when space shuttle Discovery will bring up the second Japanese component, the large Kibo pressurized laboratory.

Crew sleep cycle today: Sleep 6:00am -2:30pm; wake 2:30pm -6:00am tomorrow.

After wake-up yesterday at ~3:30pm, CDR Peggy Whitson completed another session with the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink, as suggested on her discretionary 'job jar' task list. (To monitor the crewmember's sleep/wake patterns and light exposure, Peggy wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)

EVA-3 was completed successfully by Rick Linnehan and Bob Behnken in 6h 53m, accomplishing most of its objectives.
(During the spacewalk, Linnehan (EV1) & Behnken (EV2) -

Installed the OTP (ORU {On-Orbit Replaceable Unit} Temporary Platform) and THA (Tool Holder Assembly) on the SPDM (Special Purpose Dexterous Manipulator),
Removed MLI (Multi-Layered Insulation) thermal blankets,
Installed the CLPA (Camera, Light & Pan/Tilt Assembly) on the SPDM,
Cleaned up & configured the SLP (Spacelab Pallet) for return (to be transferred with the SSRMS (Space Station Remote Manipulator System) from the POA (Payload ORU Attachment) to the Orbiter PLB (Payload Bay) tomorrow evening (FD9)),
Transferred the spare SSRMS yaw joint from the PLB to stowage on the ESP-2 (External Stowage Platform 2),
Transferred two spare DCSUs (Direct Current Switching Units) from the PLB to stowage on the ESP-2,
Transferred the LWAPA (Light Weight Adapter Plate Assembly) for installation on the Columbus EPF (External Payload Facility) and prepared for the installation of two MISSE-6 (Materials International Space Station Experiment) payloads,
Removed the MCAS EBCS (Mobil Common Attachment System External Berthing Camera System) cover flap as a get-ahead, and
Stowed the JLP (JEM Experiment Logistics Module Pressurized Section) trunnion covers on a handrail for future installation.

The crew's day started at 1:28 p.m. CDT. Their wake-up call came in the form of Ayaka Hirahara's 'Hoshi Tsumugi no Uta' -a Japanese song that translates to 'Song of Spinning Stars.' The song was played for Mission Specialist Takao Doi, a Japan Aerospace Exploration Agency astronaut.

The first robotic work of the day is scheduled to start at 3:43 p.m. when Mission Specialist Leopold Eyharts and International Space Station Flight Engineer Garrett Reisman will tuck away the arms of Dextre, the Special Purpose Dexterous Manipulator. That will prepare the robot for its move to its temporary home on a Destiny laboratory power and data grapple fixture, by Eyharts and Pilot Gregory H. Johnson.

Attaching Dextre to Destiny will free up the station's robotic arm, Canadarm2, which has been holding Dextre since early this morning. That will allow Johnson and Reisman to use Canadarm2 to remove the Spacelab Logistics Pallet that Dextre was assembled on from the station's truss and stow it back inside Endeavour's cargo bay for return to Earth. Canadarm2 will then be attached to the station's mobile base system so that it can be moved along the truss to its next worksite by Eyharts and Expedition 16 Commander Peggy Whitson.

Other activities for the day include resizing spacesuits by Mission Specialists Robert L. Behnken and Mike Foreman for their next spacewalk on flight day 11, and two hours of off-duty time for the shuttle crew members.

Crew sleep cycle today: Sleep 5:00am -1:30pm; wake 1:30pm -5:00am tomorrow.

Three more major mission steps were accomplished:

SPDM (Special Purpose Dexterous Manipulator) 'Dextre', with repositioned arms, was successfully stowed on the U.S. Lab PDGF (Power & Data Grapple Fixture) (and is looking very cool);
SLP (Spacelab Pallet) was returned to the Shuttle PLB (Payload Bay) for re-berthing; and
SSRMS (Space Station Remote Manipulator System) was 'walked off' the Node-2 PDGF onto MT/MBS (Mobile Transporter/Mobile Base System) PDGF-3 and maneuvered into position for today's MT translation from Worksite 6 (WS6) to WS4.
(During commanding of the SPDM's body ('waist') roll joint to stowage mode, it rotated in the opposite direction than expected, due to a sign mistake (polarity inversion, i.e., a plus-sign instead of a minus-sign) in the DMCS (Dexterous Manipulator Control Software) configuration file. Flight Controllers worked around this in real time, and the crew was able to maneuver the SPDM LEE (Latching End Effector) onto the LAB PDGF without further ado. Work is underway at CSA/MDA to write a corrective software patch.)

The wake-up call at 12:41 p.m. CDT was 'Burning Love' by Elvis Presley, played for Mission Specialist Mike Foreman.

For the first part of the day all of the crew members on both vehicles are scheduled off duty, a chance to relax after almost a full week of docked operations. So far they've completed three spacewalks, delivered and outfitted Japan's first space station component, and assembled and delivered a Canadian robotic attachment to its home on the station's U.S. Destiny laboratory.

At 6:08 p.m. shuttle Commander Dominic Gorie and station Commander Peggy Whitson will join Mission Specialist Takao Doi for a congratulatory phone call from Japan's prime minister, and all 10 crew members will gather at 7:58 p.m. to talk about the flight in interviews with CBS News, NBC News and WMUR-TV in Manchester, N.H.

This evening Mission Specialists Robert L. Behnken and Foreman will make preparations for Thursday's spacewalk, when they will test a heat shield repair technique. The spacewalkers will set up a caulk-gun-like tool named the Tile Repair Ablator Dispenser, which they'll use to dispense a material called Shuttle Tile Ablator-54 into purposely damaged heat shield tiles. Those test samples will be returned to Earth to undergo extensive testing on the ground.

Mission Specialist Takao Doi was joined by shuttle Commander Dom Gorie and station Commander Peggy Whitson for a phone call from Yasuo Fukuda, Japan's prime minister, who conveyed his congratulations for the successful installation of the first component of the Kibo laboratory at the station. The astronauts also answered questions from Japanese students. Afterward, all 10 crew members discussed their flight with CBS News, NBC News and WMUR-TV in Manchester, N.H.

Mission Specialists Bob Behnken and Mike Foreman, along with their spacewalk coordinator Rick Linnehan, configured the tools they will use during Thursday night's spacewalk. Behnken and Foreman will employ a tool called the Tile Repair Ablator Dispenser (T-RAD) -a caulk-gun-like device -to apply a substance called Shuttle Tile Ablator-54 (STA-54) into purposely damaged heat shield tiles. Behnken and Foreman will then smooth the substance in place with foam-tipped tools. Those test samples will be returned to Earth to undergo extensive testing on how STA-54 performs in the environment of space. The demonstration is considered important in advance of the Hubble Space Telescope servicing mission later this year since that flight will be conducted independently of a 'safe haven' capability at the ISS in the event the shuttle incurs damage to its heat shield.

Additional objectives of the spacewalk include replacement of a failed Remote Power Controller Module (RPCM) on the station's truss, including the temporary shutdown and spinup of Control Moment Gyroscope-2 (CMG). The RPCM replacement is needed to restore redundant power to CMG-2 and CMG-3.

Both crews reviewed procedures for that spacewalk, scheduled to start at 5:28 p.m. on Thursday and last 6.5 hours. Behnken and Foreman will sleep in the station's Quest airlock overnight for the standard spacewalk 'camp out' procedure to purge the nitrogen from their bodies.

The fifth and final spacewalk is scheduled for Saturday to move the shuttle's Orbiter Boom Sensor System (OBSS) onto the station. This is caused by the size of the huge Japanese Kibo pressurized laboratory module, which will be delivered to the station aboard Discovery in May, preventing the shuttle from carrying its own OBSS. Once Kibo is installed, Discovery's astronauts will detach the OBSS left behind by Endeavour, use it to perform tile inspections and bring it home.

Crew sleep/wake cycle today: Sleep 5:00am -1:30pm; wake 1:30pm -5:00am tomorrow.
FD10 was off-duty for both crews.

After wakeup yesterday at ~1:30pm EDT and before breakfast, CDR Peggy Whitson completed another session with the SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop, as suggested on her discretionary 'job jar' task list. (To monitor the crewmember's sleep/wake patterns and light exposure, Peggy wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.)

EVA-4 was completed successfully by Bob Behnken & Mike Foreman in 6h 24m, accomplishing most of its objectives.
During the spacewalk, Behnken (EV1) & Foreman (EV2) -

Demonstrated an on-orbit heat shield repair technique using the T-RAD (Tile Repair Ablator Dispenser) to demonstrate an Orbiter tile repair DTO (Development Test Objective) in space. (The spacewalkers tested STA-54, a pink putty-like material consisting of two compounds that are mixed together in a pressure-driven applicator gun just before they exit the nozzle. With Foreman working the applicator, the test was completed nominally, and the test samples were stowed in the TSA (Tool Stowage Assembly in the Orbiter PLB (Payload Bay) for return and analysis; results looked good);
Removed RPCM (Remote Power Controller Module) S02B-D on the S0 truss and replaced it with a new unit. (Since the RPCM controls CMG-2 (Control Moment Gyroscope #2), circuitry had to be powered down and the CMG-2 removed from the steering law beforehand. After the successful R&R, the spacewalkers attempted several times to reconfigure the Z1 patch panel, a pre-requisite for powering the new RPCM, but were unable to do so due to tough-to-reach connectors which could not be unmated. The patch panel reconfiguration currently remains incomplete, but there are no impacts to current operations);
Inspected the Z1 truss toolbox for MMOD (Micrometeoroid/Orbital Debris) damage and noticed several 'pits'. (Video imagery will be assessed by specialists);
Released Node-2 Port ACBM (Active Common Berthing Mechanism) launch locks in preparation for berthing the JEM (Japanese Experiment Module) module 'Kibo' on Flight 1J next May;
Removed the remaining SPDM OTCM-2 (Special Purpose Dexterous Manipulator/ORU Tool Changeout Mechanism #2) thermal covers, reconfigured some of the wrist blankets and flaps, and inspected the Shoulder Roll joint of SPDM Arm #2 for possible MLI (Multi-Layered Insulation) interference. None was seen. (WVS (Wireless Video System) helmet cam video was also obtained for ground analysis.)
Additionally, two get-ahead tasks were completed:

ISS crew sleep/wake cycle today: Sleep 3:15am -11:45am; wake 11:45am -11:00pm.

After wakeup yesterday, FE-2-16 Reisman had his third session with the biomed experiment INTEGRATED IMMUNE (Validating Procedures for Monitoring Crew member Immune Function), collecting dry saliva samples. (INTEGRATED IMMUNE protocol requires the collection to occur first thing post-sleep, before eating, drinking and brushing teeth, and all samples are stored at ambient temperature. Along with NUTRITION (Nutritional Status Assessment), IMMUNE samples & analyzes participant's blood, urine, and saliva before, during and after flight for changes related to functions like bone metabolism, oxidative damage and immune function to develop and validate an immune monitoring strategy consistent with operational flight requirements and constraints. The strategy uses both long and short duration crewmembers as study subjects. The saliva is collected in two forms, dry and liquid. The dry samples are collected at intervals during the collection day using a specialized book that contains filter paper, all stored at ambient temperature.)

STS-123/Endeavour and ISS are flying in separate orbits again (Flight Day 15/16 for STS-123/1J/A)

After final preparations on both sides of the hatches (closed yesterday on ISS side at 5:51pm EDT), Endeavour undocked last night at 8:25pm, 29 min late, from PMA-2 (Pressurized Mating Adapter 2) after a total docked time of 11d 20h 36m. (For undocking, the station was turned from -XVV through ~180 deg to +XVV ZLV (+x-axis in velocity vector, z-axis in local vertical, i.e., flying Shuttle-leading again) at ~7:09pm, put briefly on free drift for the undocking, and then moded to 1J/A Stage attitude of +XVV TEA attitude. During pre-undock feathering & locking of the station's P6 solar arrays, latch #2 of the 2B BGA (Beta Gimbal Assembly) latched only at the third attempt, delaying the undocking by ~29 min.)

Additional Details: ISS On-Orbit Status 03/25/08.

ISS crew is back on its regular work cycle: 2:00am - 5:30pm EDT.

For her VolSci (Voluntary Science) program today, CDR Peggy Whitson set up the SLAMMD (Space Linear Acceleration Mass Measurement Device) equipment on the HRF1 (Human Research Facility 1) rack, performed the scheduled checkout/control run and took a body mass measurement, documenting the activities with digital still & video imagery for ground evaluation and finally disassembling the equipment again. (SLAMMD provides an accurate means of determining the on-orbit mass of humans spanning the range from the 5th percentile Japanese female and the 95th percentile American male. The procedure, in accordance with Newton's 2nd Law of Motion, finds the mass by dividing force, generated by two springs inside the SLAMMD drawer, by acceleration measured with a precise optical instrument that detects the position versus time trajectory of the SLAMMD guide arm and a micro controller which collects the raw data and provides the precise timing. The final computation is done via portable laptop computer with SLAMMD unique software. To calculate their mass, crewmembers wrap their legs around a leg support assembly, align the stomach against a belly pad and either rest the head or chin on a head rest. For calibration, an 18-lbs. mass is used at different lengths from the pivot point, to simulate different mass values. Allowable crew mass range is from 90 to 240 lbs.)

STS-123/Endeavour returned to Earth last night after 15d 18h 11m in space, the longest Shuttle mission to ISS so far, touching down at KSC on the second opportunity at 8:39pm EDT, after 250 orbits & 6.6 million miles (first opportunity waived off due to cloud layer). (During the perfectly executed ISS 1J/AE mission, its seven-member crew conducted a record five EVAs, delivered & installed the JAXA JLP (Japanese Experiment Module Experiment Logistics Module Pressurized Section) and the Canadian SPDM Dextre, brought up new Expedition 16 crewmember Garrett Reisman and returned his predecessor Leopold Eyharts who spent 48 days in space (44 aboard the station). It was the 122nd flight of a Space Shuttle, the 25th Shuttle mission to visit the station, the 21st for Endeavour and the second of six Shuttle missions planned for 2008. Next up: STS-124/Discovery/1J on 5/25 with JAXA's JEM Pressurized Module 'Kibo', racks & the JEM RMS.)

(To monitor the crewmember's sleep/wake patterns and light exposure, Garrett wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days.)

FE-1 Yuri Malenchenko serviced the Russian BMP (Harmful Impurities Removal System), starting the "bake-out" cycle to vacuum on absorbent bed #2 of the regenerable dual-channel filtration system. The regen process was terminated before sleeptime, at ~4:30pm EDT. (Regeneration of each of the two cartridges takes about 12 hours and is conducted only during crew awake periods. Filter bed 1 was regenerated yesterday.)

The log entries are done within 15 minutes of final awakening for seven consecutive days.)

Also before breakfast, having reached the FD15 (Flight Day 15) mark in his flight, Reisman undertook his first session with the NASA/JSC experiment NUTRITION w/Repository, collecting blood and urine samples. (Acting as operator and CMO (Crew Medical Officer), CDR Whitson performed phlebotomy on Garrett, i.e., drew blood samples (from an arm vein) which were first allowed to coagulate in the Repository, then spun in the HRF RC (Human Research Facility/Refrigerated Centrifuge) and finally placed in MELFI (Minus-Eighty Laboratory Freezer for ISS). The RC was later powered off after a temperature reset to limit wear on the compressor, and cleaned. Garrett's urine samples were also placed in the MELFI. Background: NUTRITION is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight; this includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes. The Clinical Nutritional Assessment profile currently required on all U.S. Astronauts collects blood and urine samples preflight and postflight. NUTRITION expands this protocol by also capturing in-flight samples and an additional postflight sample. Furthermore, additional measurements are included for samples from all sessions, including additional markers of bone metabolism, vitamin status, and hormone and oxidative stressor tests. The results will be used to better understand the impact of countermeasures (exercise and pharmaceuticals) on nutritional status and nutrient requirements. The Clinical Nutritional Assessment profile (MR016L), first started on two Mir crewmembers and then on all ISS US crews, nominally consists of two pre-flight and one post-flight analysis of nutritional status, as well as an in-flight assessment of dietary intake using the FFQ (Food Frequency Questionnaire). The current NUTRITION project expands MR016L testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

Also upon wake-up, CDR Whitson started Part 2 (of 5) of the periodic acoustic measurement protocol by recording post-sleep data of the crew-worn acoustic dosimeters, later deploying the dosimeters statically in Node-2, COL (Columbus Orbital Laboratory), and SM (Service Module) near the Central Post for the duration of the day. (Acoustic data must be taken twice per Increment, each time for the duration of the 16-hour crew workday.)

SM hooks were closed at 10:56am. The docking was essentially a repeat of Demo Day 2 except for the final approach from S41 (~12m) to Contact and Hooks Closed. (The 19-ton unmanned ATV maneuvered from a holding position 39 km behind the ISS and conducted a 4-hour staged approach with several stops at reference points for checks. It autonomously computed its own position through relative GPS (Global Positioning System) data, comparing with GPS data received from ISS, and in close range it used VDM (Videometer) lasers pointed at LRRs (Laser Retroreflektors) on the SM for distance & orientation determination relative to its target. Final approach was at a relative velocity of 7 cm/s and with an accuracy of better than 10 cm. The cargo transport, which remains docked for the next four months, is delivering 1,150 kg of dry cargo, including food, clothes and equipment as well as two original manuscripts handwritten by Jules Verne and a 19th Century illustrated edition of his novel 'From the Earth to the Moon'. The cargo also includes 856 kg of propellant, 270 kg of drinking water and 21 kg of oxygen, to be transferred to the SM.)

This included conducting a 30-min OBT (Onboard Training) procedures review for Docked ATV Operations,
Completing a one-hour leak check of the SM PrK (Service Module Transfer Compartment)/ATV vestibule interface,
Preparing the necessary equipment for the first ingress (including GSC (Grab Sample Container), IPD-CO air sampler for CO (Carbon Monoxide), AK-1M air sampler, a manual sampling pump, goggles, a dusk mask, an A-2 air scrubber filter, etc.)
Donning the PPE (Personal Protective Equipment) i.e.,safety goggles, dust mask) (keeping PPE on until after ATV closeout operations and egress),
Opening the hatches for partial ingress (~6:20am EDT),
Installing the QD BZV (quick disconnect screw clamps) of the SSVP docking & internal transfer mechanism to rigidize the coupling,
Taking copious air samples from the ATV interior, and
Starting the air scrubber, equipped with an FPP electronic/EMI interference filter, to run for about 8h 20m with hatches closed.
For the second ingress, scheduled tomorrow (Saturday, 4/5, at ~4:00am EDT), the air scrubbing in the ATV will make the PPE unnecessary. ATV1 will then be readily accessible to the crew for nominal operations. Also scheduled for tomorrow is an ATV thruster test.

Having passed Day 180 of her flight, Dr. Peggy Whitson began her fourth session with the NASA/JSC experiment NUTRITION w/Repository, for which she had to forego exercising and food intake for eight hours. Today's protocol consisted of two blood draws (for Serum & Heparin). Later, the CDR set up the equipment for the 24-hour urine collections which start with the first void early tomorrow morning and continue through Sunday morning. (Acting as operator, CMO (Crew Medical Officer)Garrett Reisman performed phlebotomy on Peggy Whitson, i.e., drawing blood samples (from an arm vein) which was first allowed to coagulate in the Repository for 20-30 minutes, then spun in the HRF RC (Human Research Facility/Refrigerated Centrifuge) and finally placed in MELFI (Minus-Eighty Laboratory Freezer for ISS). The RC was later powered off after a temperature reset to limit wear on the compressor, and cleaned. Background: NUTRITION is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight; this includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes. The Clinical Nutritional Assessment profile currently required on all U.S. Astronauts collects blood and urine samples preflight and postflight. NUTRITION expands this protocol by also capturing inflight samples and an additional postflight sample. Furthermore, additional measurements are included for samples from all sessions, including additional markers of bone metabolism, vitamin status, and hormone and oxidative stressor tests. The results will be used to better understand the impact of countermeasures (exercise and pharmaceuticals) on nutritional status and nutrient requirements. The Clinical Nutritional Assessment profile (MR016L), first started on two Mir crewmembers and then on all ISS US crews, nominally consists of two pre-flight and one post-flight analysis of nutritional status, as well as an in-flight assessment of dietary intake using the FFQ (Food Frequency Questionnaire). The current NUTRITION project expands MR016L testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

Ahead: Week 25 of Increment 16.

Having passed Day 180 of her flight, Dr. Peggy Whitson ended her fourth session with the NASA/JSC experiment NUTRITION w/Repository by collecting a final urine sample upon wakeup for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS). The sampling kit was then stowed away. (The current NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

This morning at 4:49am EDT, Progress M-63/28P successfully undocked from the ISS. All separation burns went off nominally, and the deorbit burn followed at 7:50am for destructive reentry over the Pacific Ocean. This freed the DC1 Docking Compartment port for Soyuz TMA-12/16S docking on 4/10 at ~9:02am. (For the undocking, ISS attitude control was handed over to Russian MCS (Motion Control System) at ~2:55am and returned to U.S. momentum management at ~5:45am, still in earth-fixed LVLH (local vertical/local horizontal). During the undocking, the station was in free drift for ~9 min. Structural response data were taken by MAMS (Microgravity Acceleration Measuring System) and the external truss-mounted SDMS (Structural Dynamic Measurement System). The undocking was preceded at ~4:15am by a temporary shutdown of the amateur radio equipment in the FGB (Ericsson) & SM (Kenwood) to prevent radiofrequency interference with the departing Progress vehicle.)

Separations from second & third stage were nominal. Orbit was attained at L+ 8:45 min at an altitude of ~202 km (perigee ~189.6 km/apogee ~230.1 km, downrange ~520 km, velocity ~7.50 km/s). Antennas and solar arrays deployed nominally at orbit insertion. 16S has a planned two-day rendezvous profile, to aim for docking on Thursday, 4/10. (At orbit insertion, Soyuz unfolded two solar arrays, four Kurs antennas, one TORU/Rassvet-M antenna and one telemetry antenna. Later, the crew activated antenna heaters, set the maneuver mode, turned on the RKO orbit radio tracking system, started leak checks, etc. Two orbit adjustment burns of ~5 min duration each were executed this morning, DV1 (~25.55 m/s) at ~10:57am, DV2 (~14.27 m/s) at ~11:50am, both with the SKD main engine. After the two-day "chase", supported by several more midcourse burns, 16S will dock at the DC1 Docking Compartment on 4/10 at ~9:02am EDT.)

(FD1 activities yesterday included the first two maneuver burns, DV1 (10:57am) & DV2 (11:50am), both with the SKD main engine. FD2 activities, started yesterday afternoon with Soyuz crew wakeup at ~4:05pm on Orbit 12, include systems & crew health status reports to TsUP, preparation of the Soyuz Habitation Module (SA) workspace, building attitude for and executing the DV3 burn, placing Soyuz back in its sun-spinning "barbecue" mode (ISK), and swapping CO2 absorption cartridges (LiOH) in the BO. Afterwards, the crewmembers will put on their Sokol suits and PKO biomed harnesses, transfer to the SA, activate its air purification system (SOA) and close the hatch to the Descent Module (BO). After activation of the active Kurs-A system on Soyuz and of the passive Kurs-P on the Service Module (SM), with a short Kurs-A/P test and several additional adjustment burns during automated rendezvous, station fly-around to align with the DC1 Docking Compartment will begin tomorrow at ~8:37am at ~400m range, followed by station keeping at ~160m (~8:46am) and docking at the DC1 port at ~9:02am. Volkov & Kononenko will replace Expedition 16 CDR Whitson & FE-1 Malenchenko. FE-2 Dr. Garrett Reisman remains on the station, joining Expedition 17 until early June when he is replaced by U.S. Astronaut Gregory E. Chamitoff on STS-124/1J. So-Yeon Yi, the 30-year old biotechnologist student from KAIST (Korea Advanced Institute of Science & Technology) and South Korea's first astronaut, will return with Peggy & Yuri on 4/19 in Soyuz TMA-11/15S.)

Work period will shift again tomorrow (6:20am -5:50pm) and on 4/12 (2:10am -5:40pm).

Yest kasaniya! Soyuz TMA-12/16S docked smoothly at the DC1 port at 8:57am EDT, five minutes ahead of time, with Expedition 17 crewmembers CDR Sergei Volkov and FE-1 Oleg Kononenko, plus Korean SFP (Spaceflight Participant) So-Yeon Yi, 14th Visiting Crewmember (VC). After about 1.5 hrs spent in Soyuz on pre-transfer activities, the crew opened hatches, followed by crew transfer, the traditional joyful welcome event and the installation of the BZV QD (quick disconnect) clamps by Volkov and Kononenko at ~12:10pm. (After successful "kasaniya" (contact), automatic "sborka" (closing of Soyuz & DC1 port hooks & latches) took place shortly thereafter (~9:07am) while ISS was in free drift. Attitude control authority had been handed over to the Russian MCS (Motion Control System) at ~5:25am and was returned to US CMG control at ~10:05am. For the 16S docking, Russian thrusters were disabled during Soyuz volume pressurization and clamp installation; they were afterwards returned to active attitude control (~12:30pm). Before hatch opening, the crew performed leak checks of the Soyuz modules and the Soyuz/ISS interface vestibule. They then doffed their Sokol suits and set them up for drying (~1:05pm), deactivated the Atmosphere Pu
