4 July 2006 18:38 GMT. Landing Date: 2006-12-22 22:32:00 PM. Flight Time: 171.16 days. Flight Up: STS-121. Flight Back: STS-116. Crew: Reiter. Backup Crew: Eyharts. Program: ISS. The Astrolab Mission was Europe’s first long-duration mission to the International Space Station (ISS). Thomas Reiter lived and worked on board the ISS for five months.

French ESA astronaut Leopold Eyharts was the back-up astronaut for the mission. The mission was covered by an agreement between ESA and the Russian Federal Space Agency (Roscosmos), which covered Reiter’s flight in a shuttle crew position originally planned for a Russian cosmonaut.

During the mission, Reiter became the first ESA astronaut to serve on an ISS Expedition crew, supporting both EO-13 and EO-14 crews in the running and maintenance of the station; the first ESA astronaut to undertake a spacewalk from the ISS; conducted the first long-duration European experiment program on the ISS; and commissioned three ESA-developed experimental facilities delivered aboard STS-121.

The Astrolab experiments came from scientific institutions across Europe, and included experiments in human physiology, biology, physics and radiation dosimetry. These included operation of the Minus 80 degrees Laboratory Freezer for the ISS (MELFI); the European Modular Cultivation System (EMCS); and the Percutaneous Electrical Muscle Stimulator (PEMS).

Reiter's arrival at the ISS marked the return to three-member long-duration ISS crews, which had been reduced to two following the Columbia Space Shuttle accident in February 2003. Reiter's activities were coordinated for the first time from the Columbus Control Centre in Oberpfaffenhofen, near Munich.

ISS Astrolab Chronology

2006 Apr 7 - International Space Station Status Report: SS06-016
After orbiting Earth more than 3,000 times during six months on the International Space Station, Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev returned to the planet Sunday morning in Kazakhstan.
With them was Marcos Pontes, Brazil's first astronaut.
The Soyuz spacecraft with McArthur, Tokarev and Pontes landed in central Kazakhstan, about 30 miles northeast of Arkalyk, at 7:48 p.m. EDT, Saturday. The crew's families will greet them at Star City, Russia, near Moscow, early Monday. McArthur and Tokarev will remain in Star City for post-flight debriefings before returning to Houston later this month. McArthur and Tokarev launched from the Baikonur Cosmodrome, Kazakhstan, Sept. 30, 2005.
They spent 189 days, 18 hours and 51 minutes in space. During their mission, they conducted two spacewalks and relocated their Soyuz spacecraft twice, becoming the first ISS crew to dock to every Russian docking port on the complex. They also became the first two-person station crew to conduct a spacewalk in both Russian and U.S. spacesuits. Pontes flew to the station with the Expedition 13 crew last week as part of a commercial agreement with the Russian Federal Space Agency, Roscosmos. He spent eight days on the station conducting experiments.
The new station crew, Expedition 13 Commander Pavel Vinogradov and Flight Engineer and NASA Science Officer Jeff Williams, will have light duty for the next few days as they rest from a busy handover. They will remain in orbit for six months. The crew plans to perform two spacewalks and greet two space shuttle crews during their expedition.
Joining them during their stay on the station will be Thomas Reiter, a European Space Agency astronaut from Germany, also flying under a commercial agreement with Roscosmos. Reiter is scheduled to come to the station on the Space Shuttle Discovery's STS-121 mission, targeted for a July launch.
Reiter will be the first non-Russian, non-U.S. long-duration crew member on the station. His arrival will bring the station crew size to three for the first time since May 2003, when the crew size was reduced to conserve supplies in the wake of the Columbia accident.
Shuttle Atlantis' STS-115 mission is also scheduled during Expedition 13 and will resume major assembly of the station. The shuttle and station crews will work together to add another set of batteries and solar arrays to the complex.

2006 Apr 14 - International Space Station Status Report: SS06-017
The 13th crew of the International Space Station is wrapping up its first week flying solo in its new orbiting home.
The crew's work has included station maintenance, medical and other experiments and standard daily exercise.
Expedition 13 Commander Pavel Vinogradov and Flight Engineer and NASA Science Officer Jeff Williams said farewell to their predecessors last Saturday. The Expedition 12 crew and a visiting Brazilian astronaut undocked that afternoon and landed in Kazakhstan at 7:48 p.m. EDT.
Vinogradov and Williams had light duty Sunday and Monday, a break after completing eight days of extensive handover activities with their counterparts.
Maintenance work included a three-and-one-half hour scheduled replacement of station toilet components on Tuesday. Both crew members also took time to talk with two Russian news organizations and participants at a Russian school children's aerospace festival.
On Wednesday, Russian President Vladimir Putin called the crew from the Kremlin. Putin's call came on the 45th anniversary of the first human spaceflight by Yuri Gagarin, a landmark event commemorated by the Russian holiday Cosmonautics Day. That date, April 12, was also the 25th anniversary of the first NASA space shuttle launch in 1981.
Putin told the crew it was a pleasure to see representatives of the United States and Russia working together on the same spacecraft. During the light-hearted exchange, Vinogradov invited Putin to visit the space station.
The crew continued loading the station's Progress cargo craft with trash and conducted physical evaluations and experiments Thursday. Vinogradov and Williams practiced an emergency evacuation drill Friday. Throughout the week, they had time to familiarize themselves with their new home.
Vinogradov and Williams will remain in orbit for six months. During that time, they plan to welcome two space shuttles and perform two spacewalks. Shuttle Discovery's STS-121 mission, targeting a launch no earlier than July 1, will bring European Space Agency astronaut Thomas Reiter aboard the station.
Reiter will increase the station crew size to three for the first time since May 2003 when the crew size was reduced to conserve station supplies following the Columbia accident.
Back on Earth for almost a week, Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev remain in Star City, Russia, near Moscow. They continue to undergo debriefing and rehabilitation after 190 days in space. With them is Marcos Pontes, Brazil's first astronaut, who launched with Expedition 13. He returned to Earth with the Expedition 12 crew after spending about eight days on the station conducting experiments.
Tentative plans call for McArthur to return to Houston later this month.

2006 Apr 21 - International Space Station Status Report: SS06-018
The Expedition 13 crew this week focused on experiments, maintenance and preparations for the arrival of two and a half tons of food, supplies and equipment.
Expedition 13 Commander Pavel Vinogradov and Flight Engineer and NASA Science Officer Jeff Williams also had time set aside each day to continue to become familiar with their orbiting home.
In scientific work, Williams operated the Capillary Flow Experiment, which uses liquid silicone to study how fluids move in a microgravity environment. This portion of the experiment examined the interface between the liquid and the solid surface of the container. The results could be used by designers of systems for future spacecraft.
Williams also set up and activated cameras that will be remotely operated by middle school students to take photos of Earth through the station window. Called the Earth Knowledge Acquired by Middle School Students (EarthKAM) experiment, it allows students to study the Earth and then control a special digital camera mounted on the station. They photograph coastlines, mountain ranges and other geographic items of interest from the unique vantage point of space. More than 112 schools from eight countries have signed up for this session of the experiment. This is the 22nd time the experiment has been performed aboard the station.
Williams and Vinogradov completed the first of three sessions with the Renal Stone experiment, a study of whether potassium citrate can be used to reduce the risk of kidney stone formation. Astronauts have an increased risk of developing kidney stones because urine calcium levels are typically much higher in space. The crew recorded all consumed food and drinks and collected urine samples for later return to Earth. An understanding of the crew's diet during the urine collection timeframes will help researchers determine if the excess calcium in the urine is due to diet or a response to the microgravity environment.
The Expedition 13 crew also spent several hours practicing the use of a manual docking system for next week's arrival of the ISS Progress 21 cargo vehicle. The computer-based training will ensure they're ready to take control of the Progress if the automated system does not work properly. The 21st Progress to visit the station is scheduled to launch from the Baikonur Cosmodrome in Kazakhstan at 12:03 p.m. EDT Monday, and dock with the space station at 1:40 p.m. EDT Wednesday.
A planned reboost of the station was aborted before any engines were fired this week when downlink telemetry showed one of two sunshade covers on the Zvezda Service Module thrusters was not fully open. The station's onboard software detected that the cover was not properly opened and did not ignite the thrusters. The firing was designed to test two thrusters that have not been used since Zvezda docked to the station in July 2000. Zvezda has several other thrusters that could be used if needed. Engineers at the Russian Mission Control Center in Korolev are reviewing data and considering whether additional tests are required.
Friday the crew talked with experts in Mission Control, Houston, about an electrical repair procedure planned for Monday. The pair will replace a failed type of circuit breaker called a Remote Power Control Module (RPCM) in the Destiny Laboratory. The RPCM failed during the last crew's stay aboard the station, and power for several systems has been routed by an alternate path until it is replaced.
Vinogradov and Williams will remain in orbit for six months. During that time, they expect to welcome two space shuttles and perform two spacewalks. European Space Agency astronaut Thomas Reiter will join the Expedition 13 crew when the Space Shuttle Discovery arrives on the STS-121 mission, targeted for launch no earlier than July 1. Reiter will increase the station crew size to three for the first time since May 2003 when it was reduced to conserve supplies following the Columbia accident. The payload operations team at NASA's Marshall Space Flight Center, Huntsville, Ala., coordinates U.S. science activities on the station.

2006 Jun 23 - International Space Station Status Report: SS06-030
New supplies arrived at the International Space Station Monday as an unpiloted Russian cargo spacecraft linked up to the station's Pirs Docking Compartment.
Filled with 2.5 tons of food, fuel and supplies for the station's Expedition 13 crew, the ISS Progress 22 automatically docked at 12:25 p.m. EDT as the spacecraft and the station sailed 220 miles above northern Africa. The 22nd Progress to visit the station was launched Saturday from the Baikonur Cosmodrome in Kazakhstan.
Commander Pavel Vinogradov and Flight Engineer Jeff Williams will open the hatch to the supply ship once leak checks are completed later Monday. The crew will begin unloading items Tuesday.
The supplies include oxygen and air, clothing, experiment hardware and spare parts, as well as personal items from the crew's families. The new Progress joins an older Progress supply ship that arrived at the station's Zvezda Service Module in April. Progress 21 will remain docked until mid-September. It will be used to stow trash, and its supply of oxygen will help replenish the station's atmosphere when required.
ISS Progress 22 holds 1,918 pounds of propellant for the Russian thrusters, 108 pounds of oxygen and air as a backup supply for the oxygen generated by the Russian Elektron system and 264 pounds of water to augment onboard supplies. The new cargo also includes 2,800 pounds of spare parts, experiment hardware and life support components.
The experiment hardware includes items that will be used by European Space Agency astronaut Thomas Reiter once he arrives via the Space Shuttle Discovery's STS-121 mission. This flight will return the station to three crew members for the first time since 2003.

2006 Jun 26 - International Space Station Status Report: SS06-032
New supplies arrived at the International Space Station Monday as an unpiloted Russian cargo spacecraft linked up to the Pirs Docking Compartment.
Filled with 2.5 tons of food, fuel and supplies for the station's Expedition 13 crew, the ISS Progress 22 automatically docked to the Pirs airlock at 11:25 a.m. CDT as the spacecraft and the station sailed 220 miles above northern Africa. The 22nd Progress to visit the station was launched Saturday from the Baikonur Cosmodrome in Kazakhstan.
Commander Pavel Vinogradov and Flight Engineer Jeff Williams will open the hatch to the supply ship once leak checks are completed later Monday. The crew will begin unloading items Tuesday.

2006 Jun 30 - International Space Station Status Report: SS06-033
The Expedition 13 crew welcomed a Russian resupply ship this week and prepared for the arrival of Space Shuttle Discovery.
Discovery’s launch is scheduled for 3:49 p.m. EDT Saturday. Discovery's STS-121 mission will return the station to three crew members for the first time since 2003, when European Space Agency astronaut Thomas Reiter joins crew members Jeff Williams, flight engineer and Pavel Vinogradov, commander. To get ready for upcoming STS-121 spacewalks, the crew flushed cooling loops in the Quest airlock and U.S. spacesuits, configured airlock systems and tools, and reviewed robotic arm procedures. They checked out a ship-to-ship communications system that will be used for conversations with Discovery's crew during rendezvous and disconnected the station’s Common Cabin Air Assembly heat exchanger. That device will be returned to Earth aboard Discovery along with other equipment in the Italian-built Leonardo Multipurpose Logistics Module. Discovery will bring about 5,000 pounds of supplies to the station carried aboard the logistics module.
The crew also completed a mid-mission session of the renal stone experiment by collecting urine samples and logging all of the food and drinks consumed over a three-day period. Each crewmember is taking either potassium citrate, a drug found to be useful in preventing kidney stone formation on Earth, or a placebo. Crews in space are at risk for kidney stones linked to their loss of bone density.
ISS Progress 22, the unpiloted Russian cargo spacecraft, brought 2.5 tons of fresh produce, other foodstuffs, food, fuel and supplies to the station June 26. After the cargo ship was fully connected with station systems, flight controllers in Moscow completed a routine thruster test and Vinogradov removed its Kurs automated rendezvous hardware.

2006 Jul 4 - STS-121 Crew: Lindsey, Kelly Mark, Fossum, Nowak, Wilson, Sellers, Reiter. Spacecraft: Discovery. Payload: Discovery F32 / Leonardo. Mass: 121,094 kg (266,966 lb). Launch Site: Cape Canaveral. Launch Vehicle: Shuttle. Duration: 12.78 days. Perigee: 332 km (206 mi). Apogee: 351 km (218 mi). Inclination: 51.60 deg. Period: 91.40 min.
The shuttle was launched using external tank ET-119 and solid motors RSRM-93. Cameras revealed that large chunks of foam were still shed from the external tank during the ascent to orbit. However examination of the heat shield using a new extension and sensors attached to the shuttle's robot arm revealed no significant damage. Discovery docked with the PMA-2 adapter on the Destiny module of the ISS at 14:52 GMT on 6 July. On July 7 the Leonardo cargo module was moved from the shuttle payload bay by the robot arm and docked to the Unity Module of the ISS between 09:42 and 11:50 GMT. The crew then began unloading the spare parts and supplies in the module to the station. A series of three EVAs conducted on 8 to 12 July tested the new equipment and techniques for repairing the shuttle heat shield in case of damage, and did some preliminary installations on the exterior of the ISS to pave the way for continued station assembly missions. On 14 July, the station's SSRMS robot moved the Leonardo module from the station back to the shuttle cargo bay between 13:08 and 14:50 GMT. The shuttle separated from the ISS, and fired its engines at 12:07 GMT on 17 July to make a 92 m/s deorbit maneuver. Discovery landed at the Kennedy Space Center at 13:14 GMT. European astronaut Reiter was left behind to make up part of the EO-13 resident crew on the station.

2006 Jul 4 - STS-121 MCC Status Report #01
On the nation’s 230th birthday, Discovery rocketed into the Florida sky this afternoon, returning the shuttle fleet to space after almost a year.
The first human spacecraft to launch on an Independence Day holiday, Discovery has begun a journey to resupply and service the International Space Station. Commander Steve Lindsey, Pilot Mark Kelly and Mission Specialists Mike Fossum, Lisa Nowak, Stephanie Wilson, Piers Sellers and Thomas Reiter, a European Space Agency astronaut, lifted off at 1:38 p.m. CDT. The launch followed a flawless countdown.
During the next 12 days, Discovery’s crew will demonstrate techniques for inspecting and protecting the shuttle’s thermal protection system, restore the station to a three-person crew for the first time since May 2003, and replace critical hardware needed for future station assembly. The crew is planned to conduct two spacewalks during the mission. If supplies allow, managers may extend Discovery's flight by an additional day, a day that will be used by the crew to conduct a third spacewalk.
A system of new and upgraded ground-based cameras, radar and airborne cameras aboard high altitude aircraft documented Discovery's launch. That imagery, along with data to be gathered from in-flight inspections, will be used to ensure Discovery's heat shield is in good condition. The in-flight inspections will be performed by the crew using the shuttle's robotic arm, an extension boom and laser system as well as photography to be taken from the station of a back flip the shuttle will perform as it approaches for docking.
Moments after main engine cutoff, less than nine minutes after liftoff, Fossum and Wilson used handheld video and digital still cameras to document the external tank after it separated from the shuttle. That imagery, as well as imagery gathered by cameras in the shuttle’s umbilical well where the tank was connected, will be transmitted to the ground for review.
As Discovery lifted off, the International Space Station was 220 miles above the southern Pacific Ocean, south of Tasmania. Aboard the outpost, Expedition 13 Commander Pavel Vinogradov and Flight Engineer and NASA Science Officer Jeff Williams watched the launch via a television transmission from Mission Control. Discovery is set to dock to the complex at about 9:51 a.m. CDT July 6.
The shuttle crew will test Discovery’s robot arm tomorrow and then use it to grasp a 50-foot long boom extension, called the Orbiter Boom Sensor System. That boom holds the laser system and TV cameras they will use to inspect the shuttle’s wings and heat shield.
During the two spacewalks, Sellers and Fossum will test the capability of the boom extension to be used as a work platform from which repairs could be performed to the shuttle heat shield. They also will repair a cable system on the station’s rail car, a system that will be a base for the station's robotic arm for future assembly work. If the mission is extended by a day, the third spacewalk will be used to test techniques under development for repair of the reinforced carbon-carbon that makes up the heat shield on the shuttle wing edges.
Carried inside the Leonardo multi-purpose logistics module in Discovery’s cargo bay and elsewhere on the shuttle, about 14 tons of hardware and supplies is on its way to the space station. Discovery's crew begins an eight-hour sleep period at 7:38 p.m. CDT. The astronauts will awaken at 3:38 a.m. CDT Wednesday to begin their first full day in orbit.

2006 Jul 5 - STS-121 MCC Status Report #02
Discovery's astronauts are awake and ready to begin their first full day in space.
Today the crew will focus on thermal protection system inspections, preparing for docking to the International Space Station and getting spacesuits ready for two and perhaps three spacewalks.
Commander Steve Lindsey, Pilot Mark Kelly and Mission Specialists Mike Fossum, Lisa Nowak, Stephanie Wilson, Piers Sellers and Thomas Reiter got their wakeup call at 4:08 a.m. CDT, allowing them an extra 30 minutes of sleep after their first day in space ran long. The wakeup song was “Lift Every Voice and Sing” performed by the New Galveston Chorale.
Four crewmembers will spend much of the day looking for damage to Discovery's thermal protection system. Lindsey, Kelly, Fossum and Nowak will use the Orbiter Boom Sensor System (OBSS), a 50-foot boom on the end of the shuttle's robotic Canadarm, to look at the wings' leading edges and the nose cap.
The task involves about 6½ hours of intense work for the crew members. Actual data takes will total about an hour, 20 minutes for each wing and the nose cap. The rest of that time is devoted to very careful movement of the Canadarm and the OBSS.
Later, after lunch, Nowak and Wilson will return the OBSS to its berth on the starboard sill of Discovery's cargo bay. Then they and Fossum will use cameras on the shuttle arm to photograph the outside of Discovery's cabin. That activity should take about an hour.
Wilson also will take digital hand-held camera photos of the orbital maneuvering system pods at the base of the shuttle's vertical tail fin.
Photos and sensor readings from the shuttle, as well as photos of launch and ascent from more than 100 ground-based and airborne cameras and radar and instrument data, will be reviewed by experts on the ground. The data, photos by the station crew and information from subsequent arm surveys at the station and after undocking, will be used to determine if Discovery sustained damage during launch and ascent or in space, to ensure that it is safe for the shuttle to re-enter the atmosphere to land.
In other activities today, Wilson and Reiter will get items on the middeck ready for transfer to the station. Spacewalkers Fossum and Sellers, helped by Kelly, the intravehicular officer who will coach the spacewalkers, will check out spacesuits.
Nowak and Sellers will extend the shuttle docking ring which will help secure Discovery to the station. Just before the shuttle crew goes to bed, Kelly and Sellers will check out and prepare docking tools, including laptop computers.
At 3:30 a.m., Discovery was trailing the station by 9,573 statute miles and closing at a rate of 870 statute miles per orbit. Docking is scheduled for 9:52 a.m. Thursday.
Today the space station crew, Commander Pavel Vinogradov and NASA Science Officer Jeff Williams, will continue to prepare the orbiting laboratory for Discovery's arrival. They will ready the digital cameras with 400mm and 800mm lenses they will use during Discovery’s approach to take high-resolution photos of the shuttle's heat shield. They also will pressurize the Pressurized Mating Adapter 2 at the end of the U.S. laboratory Destiny, where Discovery is scheduled to dock.

2006 Jul 5 - STS-121 MCC Status Report #03
The Astronauts of Space Shuttle Discovery examined their spaceship with the Orbiter Boom Sensor System today and found no evidence of any damage from debris during yesterday’s ride to orbit.
The several hours of inspection began just after 6:00 a.m. when Mission Specialists Lisa Nowak and Stephanie Wilson verified proper operation of the Space Shuttle’s robotic arm, then maneuvered it to lift the 50-foot-long OBSS from the starboard sill of the payload bay.
Assisted by Commander Steve Lindsey, Pilot Mark Kelly and Mission Specialist Mike Fossum, Nowak and Wilson began a slow and steady examination of the reinforced carbon-carbon panels along the leading edge of Discovery’s starboard wing just before 8:30 a.m., looking for any evidence of damage.
The inspection using the Laser Dynamic Range Imager, Laser Camera System, and Intensified Television Camera on the end of the boom continued across the shuttle’s nose cap and port wing. After returning the OBSS to its berth, Nowak, Wilson and Fossum spent an hour using the cameras on the shuttle robot arm to scan the outside of the crew cabin.
While the survey proceeded, Mission Specialist Piers Sellers completed the setup of on board computers and cameras and Mission Specialist Thomas Reiter of the European Space Agency prepared Discovery’s middeck for the planned transfer of supplies onto the International Space Station. The first item to be transferred after docking, scheduled for 9:52 a.m. Thursday, is Reiter’s customized seat liner for the Soyuz vehicle; that will make him an official member of the station’s Expedition 13 crew, and the first ISS crewmember who is neither an American nor a Russian.
Sellers and Fossum, who also installed the centerline camera in Discovery’s docking mechanism, completed a checkout of the spacesuits they will wear during scheduled spacewalks on Flight Days 5 and 7. The EVAs will evaluate the combination of ISS robot arm and OBSS as a work platform for astronauts repairing a damaged shuttle orbiter and restore the station’s Mobile Transporter to full operation to support continued station assembly.
On board ISS Commander Pavel Vinogradov and Flight Engineer Jeff Williams prepared the digital cameras with 400mm and 800mm lenses they will use to take high-resolution photos of the shuttle's heat shield when it flies a nose over tail somersault at a range of 600 feet below the station. They also prepared Pressurized Mating Adapter 2, at the forward end of the U.S. laboratory Destiny, where Discovery will dock tomorrow morning.
The astronauts on Discovery were scheduled to be awakened at 2:38 a.m. CDT Thursday to being final preparations for the docking with the ISS.

2006 Jul 6 - STS-121 MCC Status Report #04
A third crewmember will join the International Space Station today after the docking of the Space Shuttle Discovery.
It will mark the first time since May 2003 that more than two long-duration crew members have called the orbiting laboratory home.
Discovery, with Commander Steve Lindsey, Pilot Mark Kelly and Mission Specialists Mike Fossum, Lisa Nowak, Stephanie Wilson, Piers Sellers and Thomas Reiter aboard, is scheduled to dock with the station at 9:52 a.m. CDT.
Shortly after the welcome by station Commander Pavel Vinogradov and NASA Science Officer Jeff Williams and a mandatory safety briefing, Reiter will transfer his seat liner to the Soyuz spacecraft attached to the station, making him an official station crewmember. Reiter is a European Space Agency astronaut from Germany, flying under a contract between ESA and the Russian Federal Space Agency.
During Discovery’s approach to the station, Lindsey will pilot the shuttle on what amounts to a back flip, called the Rendezvous Pitch Maneuver. At about 600 feet below the station, the flip will give Vinogradov and Williams a chance to photograph the thermal protection tiles on the bottom of Discovery. Using digital cameras with 400mm and 800mm lenses, they will take a carefully planned series of photos of the shuttle's underside.
The images will be downlinked for study by experts on the ground, starting with the more detailed images from the 800mm lens. More 800mm photos will be taken than during Discovery's approach during STS-114. One increased photo emphasis will be looking for protruding gap fillers, like those removed by STS-114 spacewalker Steve Robinson last year.
These photos and other data, including images from more than 100 cameras on the ground, in aircraft and on the shuttle, as well as data from the shuttle arm and the Orbital Boom Sensor System (OBSS) attached to it, will be used, along with data from subsequent surveys, to make sure that Discovery sustained no major damage on launch, ascent and in orbit.
About three hours after docking, both crews get to work with more robotic operations to prepare for additional surveys. Nowak, Wilson and Williams will operate the space station robotic arm, Canadarm2, from inside the Destiny Lab.
They will use the arm to lift the OBSS from Discovery's payload bay sill and hand it over to the shuttle arm, operated by Lindsey and Fossum. Clearance restraints around the shuttle’s docking mechanism do not allow the shuttle arm to grapple the boom on its own.
Transfer of cargo from the shuttle's middeck including spacesuits will begin shortly after docking. At least two spacewalks are scheduled, one on Saturday and another on Monday. A third may be done if the mission is extended a day.
Discovery’s crew was awakened at 2:38 a.m. Thursday by "Daniel," performed by Elton John and dedicated to Reiter. The station crew was awakened at the same time by its standard wakeup tone.

2006 Jul 6 - STS-121 MCC Status Report #05
There is a crew of three aboard the International Space Station today for the first time in more than three years, and for the first time ever that crew includes an American, a Russian and a European.
European Space Agency astronaut Thomas Reiter of Germany was delivered as the newest member of ISS Expedition 13 just hours after Space Shuttle Discovery docked at the station’s Pressurized Mating Adapter 2 at 9:52 a.m. CDT, as the two ships flew above the south Pacific Ocean south of Pitcairn Island.
Commander Steve Lindsey piloted Discovery’s approach to ISS, halting 600 feet directly below the station to perform the rendezvous pitch maneuver: the shuttle was commanded to do a nose-over-tail somersault so ISS Commander Pavel Vinogradov and Flight Engineer Jeff Williams could photograph the thermal protection system tiles on the orbiter’s underside. Imagery experts on the ground will study the high-resolution still pictures for evidence of any damage to the insulating tiles.
Lindsey and his crew—Pilot Mark Kelly and Mission Specialists Mike Fossum, Lisa Nowak, Stephanie Wilson, Piers Sellers and Reiter—greeted the station crewmembers when the hatches between the vehicles were opened at 11:30 a.m. CDT.
After Vinogradov’s safety briefing for the shuttle crew, he helped Reiter install his customized Soyuz seat liner into the Russian rescue vehicle and check his pressurized Sokol suit, finalizing Reiter’s transfer from Discovery to ISS. Other first-day transfers from Discovery included the spacesuits that Sellers and Fossum will wear on their spacewalks out of the Quest airlock on Flight Days 5 and 7.
In preparation for the first EVA, Nowak, Wilson and Williams lifted the Orbiter Boom Sensor System with the station’s robotic arm and handed it over to the shuttle’s robotic arm. During the first spacewalk Sellers and Fossum will simulate orbiter repair tasks while attached to the OBSS/shuttle arm combination to test that 100-foot-long construction crane as a work platform.
On the second spacewalk the astronauts will deliver a spare Pump Module to an external stowage platform before replacing a damaged power and data cable reel assembly in the station’s truss. The repair will allow the Mobile Transporter to move along the truss during installation of new truss segments on future shuttle assembly missions.

2006 Jul 7 - STS-121 MCC Status Report #06
After a successful docking to the International Space Station Thursday, the focus of the STS-121 shuttle mission now turns to unloading more than 7,000 lbs of cargo, continued shuttle inspections and preparations for the mission’s first spacewalk.
The first task of the day will be the relocation of the Leonardo Multi-Purpose Logistics Module (MPLM) from the shuttle payload bay onto the station’s Unity Module. Mission Specialists Lisa Nowak, Stephanie Wilson, Mike Fossum and Piers Sellers will use the station robotic arm, Canadarm2, to maneuver the module, with help from pilot Mark Kelly.
Once successfully mated to its temporary position on the station, shuttle Commander Steve Lindsey and new Expedition 13 Flight Engineer Thomas Reiter will conduct leak checks and enter the pressurized cargo container. Wilson will lead the transfer activities, which are scheduled to continue until next Thursday.
Later, using the shuttle robotic arm and boom system, Kelly, Nowak and Wilson will conduct additional inspections of the orbiter’s thermal protection system. They will target a few specific areas on the shuttle’s nose cap that were missed on the initial scans, as well as two gap fillers that appear to be protruding from Discovery’s underside. They also intend to get a closer look at a piece of fabric near the shuttle nose.
Fossum and Sellers will make preparations for Saturday’s planned spacewalk. They will configure tools and the U.S. airlock Quest for the spacewalk. They will repair the station's mobile transporter and test the capability of the robotic arm boom extension to carry spacewalkers. The results of that test will help engineers understand the feasibility of using the arm for thermal system inspections and repairs if needed on later flights.
The crew has time set aside at the end of the day for a review of the spacewalk procedures.
The newly augmented space station crew, including Flight Engineer Jeff Williams and Commander Pavel Vinogradov, will work closely with the shuttle crew, assisting with transfer activities and robotic arm operations.
Some crewmembers will talk with journalists. Lindsey and Kelly will chat in the morning with radio reporters from CBS, Fox, ABC and National Public Radio. Toward the end of the day, the Expedition crew will speak with CNN, CBS News and the Associated Press.
The space shuttle crew awoke at 2:14 a.m. CDT by the Beatles’ "Good Day Sunshine" dedicated to first time spaceflyer Lisa Nowak. The Expedition 13 crew awoke 30 minutes later with their standard wake up tone.

2006 Jul 8 - STS-121 MCC Status Report #08
The first spacewalk of Discovery's STS-121 mission to the International Space Station will highlight Saturday activities for crews of both docked spacecraft.
Spacewalkers Piers Sellers and Mike Fossum have two major tasks. First they will work to ensure that the second power and data cable linking the mobile transporter to the rest of the station is spared the fate of the mobile transporter's other trailing umbilical system cable. It was inadvertently severed by its safety cutter last December. The second activity is to test the capability of the shuttle's robotic arm and its 50-foot extension to act as a platform for spacewalkers making repairs.
Expedition 12 crewmembers tried to install a safety bolt to protect the remaining cable. They were unable to insert the bolt, so they removed the cable from the emergency cutter.
Sellers and Fossum will install a device to block the cutter blade. If that doesn't work, they'll install a new unit, called an interface umbilical assembly, this one without a blade. Once they reinstall the cable, the mobile transporter will again be able to move the station's robotic arm along the rails on the station's main truss. The arm is scheduled to be moved during the Monday spacewalk.
For the test of the arm as a repair platform, Sellers will work on the end of the 50- foot extension, called the orbital boom sensor system. Then both spacewalkers will simulate working motions at the end of the extension. That will be done in at least three arm positions.
Sellers will be the lead spacewalker and wear the spacesuit with red stripes. He did three spacewalks in October 2002 during the STS-112 mission of Atlantis to the station. On that mission he helped install the station's starboard one (S1) truss.
Fossum will wear the all-white spacesuit. He is making his first spaceflight. Discovery Pilot Mark Kelly will serve as the intravehicular officer, coaching and helping the spacewalkers from inside the station-shuttle complex.
Mission Specialists Lisa Nowak and Stephanie Wilson will operate the robotic arms during all three of the mission's spacewalks. They will maneuver the shuttle's Canadarm with its extension during the first, scheduled to begin at 8:13 a.m. CDT Saturday. They will use the station's Canadarm2 during the second spacewalk on Monday and the third on Wednesday.
Expedition 13 Flight Engineer and NASA Science Officer Jeff Williams and Discovery Commander Steve Lindsey also will help out during the spacewalk.
Meanwhile Thomas Reiter, the European Space Agency astronaut from Germany who became part of the Expedition 13 crew shortly after docking, will work with station commander Pavel Vinogradov to transfer cargo and equipment from the Leonardo multi-purpose logistics module.
In staggered wake ups, the shuttle crew arose at 2:08 a.m. CDT to the sound of "God of Wonders" by Marc Byrd and Steve Hindalong. The music was selected for Fossum by his family. The station crew was awakened about 30 minutes later.

2006 Jul 8 - STS-121 MCC Status Report #09
Astronauts from Space Shuttle Discovery prepared the International Space Station’s rail car for restoration and tested a repair crane during a 7 hour 31 minute long spacewalk today, while their colleagues delivered a new oxygen generator and laboratory freezer to the station.
Mission Specialists Piers Sellers and Mike Fossum turned their spacesuits to battery power to officially start the spacewalk at 8:17 a.m. CDT. After they configured their tools and safety tethers, they moved to the S0 Truss and installed a blade blocker in the zenith Interface Umbilical Assembly to protect the undamaged power, data and video cable. Then they rerouted that cable through the IUA so the Mobile Transporter rail car could be moved into position on the truss for replacement of the Trailing Umbilical System containing the severed power and data cable during a spacewalk Monday.
The remainder of today’s spacewalk was devoted to testing the combination of space shuttle robotic arm and Orbiter Boom Sensor System as a platform for spacewalking astronauts to make repairs to a damaged orbiter. Sellers got into a foot restraint on the OBSS, almost 100 feet from where the shuttle arm is attached to the payload bay sill, and performed a set of motions designed to see how the arm/OBSS handled the forces generated by those movements; Fossum stood nearby and reported his observations of the arm/OBSS’ movements.
Then Fossum joined Sellers on the end of the OBSS for another round of demonstrations, with measurements again taken by a load cell mounted under the foot restraint. For the last measurement the arm maneuvered Fossum into position so he could push against the end of the P1 Truss.
Sellers, wearing the spacesuit with red stripes, and Fossum, wearing the white spacesuit, re-entered the station and started pressurizing the airlock at 3:48 p.m., concluding the first of three spacewalks planned for the mission. Today’s EVA was the fourth of Sellers’ career, and the first for Fossum.
Pilot Mark Kelly served as intravehicular crewmember, keeping the spacewalkers on time and relaying information from Mission Control in Houston, while Mission Specialists Lisa Nowak and Stephanie Wilson and Expedition 13 Flight Engineer Jeff Williams operated the shuttle robot arm and Discovery Commander Steve Lindsey monitored their activities while transferring water onto ISS.
During the EVA ISS Commander Pavel Vinogradov and Flight Engineer Thomas Reiter unloaded cargo from the Multipurpose Logistics Module. Today’s transfers included a new oxygen generator, to be installed in the Destiny laboratory in the coming months, and a Minus Eighty Degree Laboratory Freezer for ISS, which will provide low temperature storage for lab supplies and for experiment samples awaiting return to Earth.
Delivery of cargo from the MPLM onto ISS will be the centerpiece of activity on orbit Sunday, and the second of two spacewalks will take place Monday morning at 7:13 a.m. CDT.
Also Saturday, Mission Managers reported clearing for entry all but one area of the orbiter’s thermal protection system that engineers had been looking at closely. The remaining area, a protruding gap filler near the external tank umbilical doors, needs further analysis, according to Steve Poulos, Orbiter Project Office Manager. The outlook was favorable for clearing that area, as well, Poulos said, but image analysts will be working through the night Saturday to finish looking at it.
Overall, the spacecraft thermal protection system had relatively few “dings” and Chairman of the Mission Management Team John Shannon said that Discovery was by far the "cleanest" in terms of damage to the heat shield.

2006 Jul 9 - STS-121 MCC Status Report #11
Delivering the equipment and supplies loaded in an Italian-built moving van was the primary activity for the crews of Space Shuttle Discovery and the International Space Station today.
The astronauts also made preparations for the second spacewalk during joint docked operations, scheduled for Monday morning.
Leonardo, the Multipurpose Logistics Module that rode to orbit in the shuttle payload bay, launched with more than 7,400 pounds of new space station equipment and crew supplies. Today’s operations included transfer of a new heat exchanger for the Common Cabin Air Assembly, a component of the ISS environmental control system which collects condensate out of the air, and a spare U.S. spacewalk suit and emergency jet pack.
As they deliver the module’s contents onto the station, the astronauts are also refilling Leonardo with almost 4,400 pounds of material no longer needed on the station. That includes experiment samples, trash, and broken equipment.
For several hours today Mission Specialists Piers Sellers and Mike Fossum refreshed the systems of their spacesuits and prepared tools and equipment for tomorrow’s EVA. During that planned six and a half hour excursion, scheduled to begin at 7:13 a.m. CDT, they will deliver a spare cooling system Pump Module to a stowage platform and replace the Trailing Umbilical System on the nadir side of the S0 Truss. That replacement will give the station’s Mobile Transporter rail car a redundant pair of power, data and video cables so it can translate along the truss in support of future station assembly tasks.
Earlier today, Discovery Commander Steve Lindsey, Pilot Mark Kelly, and Mission Specialists Lisa Nowak, Stephanie Wilson, Fossum and Sellers joined Expedition 13 Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter to answer questions about their missions from reporters at NASA centers and at the European Astronaut Center in Cologne, Germany.
Late today John Shannon, the deputy shuttle program manager and chairman of the STS-121 Mission Management Team, reported that mission managers cleared Discovery for its return to Earth, declaring that the shuttle’s heat shield was free from any damage. The crew will conduct another inspection later in the mission looking for any other evidence of damage done by orbital debris prior to landing.
Discovery’s crew began its sleep period just after 5 p.m. CDT and will be awakened at 1:08 a.m. CDT Monday to begin the seventh day of the flight.

2006 Jul 10 - STS-121 MCC Status Report #12
Discovery Mission Specialists Mike Fossum and Piers Sellers will work on the International Space Station’s mobile transporter and install a pump module today on the second of three spacewalks of the STS-121 mission.
The shuttle crew was awakened at 1:08 a.m. CDT by "Clocks," performed by Coldplay. It was requested by Sellers' family for the day of the second spacewalk.
The spacewalk is scheduled to begin at 7:13 a.m. and expected to last nearly seven hours. First, Fossum and Sellers will make their way to the shuttle’s payload bay to a spare pump module for the station’s thermal control system. Once there, they will attach it to the fixed grapple bar which will allow Mission Specialists Lisa Nowak and Stephanie Wilson, inside at the controls of the robotic arm, to maneuver the pump to the external stowage platform.
While the module is being moved, Fossum and Sellers will stay in the payload bay and get ready for their next task, replacement of a trailing umbilical system (TUS) reel assembly, this one on the nadir side of the mobile transporter.
After they reconfigure the payload bay for the activity, they’ll then translate to the starboard zero truss segment, to get it ready for retrieval. Fossum will disconnect electrical cables while Sellers changes out the assembly. Once it is ready, they will leave that site to go to the stowage platform and assist with the detaching and installation of the pump into its permanent storage location. That pump is onboard as a spare should it be needed in the future.
The two spacewalkers will then return to the truss and remove the TUS reel assembly. Fossum, on the end of the robotic arm, will take the reel assembly to the payload bay. Sellers will move there on his own, and set up for the swap of that assembly with a new one. After the swap is complete, the two will go back to the worksite to install the new reel assembly, reroute the power and data cable and thus restoring the desired redundancy to the mobile transporter and enabling it again to be used for continued station assembly tasks.
Shuttle Commander Steve Lindsey and Pilot Mark Kelly will support the spacewalk with Lindsey monitoring the vehicle systems and video/television set ups and Kelly overseeing activities and coaching the spacewalkers.
The Expedition 13 crew, Commander Pavel Vinogradov and flight engineers Jeff Williams and Thomas Reiter, will be working steadily throughout the day transferring trash and unneeded equipment and supplies for return to Earth in the multipurpose logistics module Leonardo. More than 4,300 pounds of cargo will be packed for the return to Earth.

2006 Jul 10 - STS-121 MCC Status Report #13
A six-hour, 47-minute spacewalk by astronauts from Space Shuttle Discovery today restored the International Space Station’s Mobile Transporter rail car to full operation and delivered a spare pump module for the station’s cooling system.
Spacewalkers Piers Sellers and Mike Fossum exited the Quest module’s airlock at 7:14 a.m. and climbed down into the shuttle payload bay, where they lifted the Pump Module from its stowage platform so Mission Specialists Lisa Nowak and Stephanie Wilson could grapple it with the station’s 58-foot-long robotic arm. While the arm moved the module to its destination, Sellers and Fossum moved to the S0 Truss segment to begin work on the primary task of the EVA, replacement of the nadir-side Trailing Umbilical System (TUS).
A TUS contains a power, data and video cable that serves the Mobile Transporter as it moves along the station’s truss; the nadir TUS cable was inadvertently severed late last year and required replacement. As the first step in that process Sellers replaced the Interface Umbilical Assembly - the component containing the cutter - with a new IUA, one without a blade.
By that time, Canadarm2 reached External Stowage Platform 2 on the forward side of Quest with the Pump Module; Sellers and Fossum moved to the platform to receive the module from the arm, secured it to the storage platform, and returned to the TUS work site.
The spacewalkers removed the damaged TUS from within the S0 Truss, and Fossum carried it to the payload bay while riding the station arm. When he arrived, Sellers removed the new TUS from the payload bay platform, and the two swapped cable reels. Sellers stowed the old TUS on the cross-bay carrier while the arm moved Fossum back to the truss work site, where Sellers rejoined his crewmate to complete installation of the TUS and properly route its power, data and video cable through the IUA.
At two points during the spacewalk Fossum paused to take care of a loose connection of the emergency jet thruster backpack on Sellers’ spacesuit, securing it the first time with a safety tether.
The spacewalkers closed the hatch and began to repressurize Quest to end the spacewalk at 2:01 p.m. to conclude a six-hour, 47-minute excursion; the combined time spent spacewalking on two EVAs on this mission so far is 14 hours, 18 minutes. A third spacewalk, devoted to testing potential repair techniques and materials, is scheduled for Wednesday.
During the spacewalk Pilot Mark Kelly oversaw the timeline for the spacewalkers while Commander Steve Lindsey managed the cameras and transferred two containers of water onto ISS. Expedition 13 Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter continued to work on delivery and stowage of equipment and supplies from the Multipurpose Logistics Module.

2006 Jul 11 - STS-121 MCC Status Report #14
Repacking the multi-purpose logistics module Leonardo will be the focus of today’s activities for the Space Shuttle Discovery and International Space Station crews.
More than 4,300 pounds of experiment results, unneeded hardware and trash is scheduled to be loaded onto the pressurized cargo module for return to Earth in Discovery's cargo bay next week. Mission Specialist Stephanie Wilson serves as the loadmaster for the extensive transfer activity.
All nine shuttle and station crew members will help gather and stow the return cargo in Leonardo. It brought more than 7,000 pounds of clothing, food and other supplies for the station.
Throughout the day, Mission Specialists Mike Fossum and Piers Sellers will also have spacewalk preparation tasks. They’ll recharge the spacesuits, gather and organize needed tools, and configure the airlock.
Before the day’s end, they’ll be joined by Commander Steve Lindsey, Pilot Mark Kelly, and fellow Mission Specialists Lisa Nowak and Stephanie Wilson for a review of the spacewalk procedures.
Kelly, Fossum, Nowak, Wilson and Sellers will talk with representatives from the Associated Press and USA Today. That 20-minute chat is scheduled to begin at 7:18 a.m. CDT.
The shuttle crew was awakened at 1:08 a.m. by "All Star," performed by Smashmouth. It was for Nowak, requested by her family.
Expedition 13 Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter were awakened 30 minutes later, at 1:38 a.m.

2006 Jul 11 - STS-121 MCC Status Report #15
In between spacewalks, the joint crews aboard Space Shuttle Discovery and the International Space Station today turned their attention to packing the Leonardo logistics module in preparation for its return to Earth.
Additional time was set aside today for procedural review for the third spacewalk planned to begin at 6:13 a.m. CDT Wednesday.
Expedition 13 Commander Pavel Vinogradov along with Flight Engineers Jeff Williams and Thomas Reiter spent most of the day loading items no longer needed on the station into the Multipurpose Logistics Module docked to the station’s Unity module. Before being returned to Discovery’s payload bay on Friday, the Italian-built Leonardo will be filled with almost 4,400 pounds of experiment samples, unneeded hardware and trash.
Included in the more than 7,400 pounds of supplies delivered to the station was a new window and window seals for the Microgravity Science Glovebox, a European Space Agency-developed enclosed workspace for science experiments involving fluids, flames, particles or fumes. Reiter, the ESA astronaut who joined the station crew last week, installed the new window and window seals today. Additional work will be needed after the shuttle departs before the MSG can resume operation.
Discovery Mission Specialists Piers Sellers and Mike Fossum, who already have spent 14 hours and 18 minutes outside the Discovery/ISS complex on two spacewalks, devoted much of the day to preparing their spacesuits and tools for the mission’s third Extravehicular Activity. The planned 6-½ hour spacewalk is devoted to testing a non-oxide adhesive as a repair material for the reinforced carbon carbon panels that line a shuttle’s leading edge, and the use of an infrared camera to detect unseen damage to RCC.
At 7:18 this morning the spacewalkers joined Pilot Mark Kelly and Mission Specialists Lisa Nowak and Stephanie Wilson to talk about the progress of their flight in interviews with the Associated Press and USA Today.

2006 Jul 12 - STS-121 MCC Status Report #16
The third and final spacewalk of the STS-121 space shuttle mission will be the focus of today’s space activities.
Mission Specialists Mike Fossum and Piers Sellers will test techniques to inspect and repair damage to an orbiter's heat shield. The 6.5-hour spacewalk from the Quest airlock is scheduled to start at 6:13 a.m. CDT.
Sellers and Fossum will set up tools and a foot restraint on the station robotic arm. Sellers will position himself on the arm, operated by Mission Specialists Lisa Nowak and Stephanie Wilson. He will use an infrared camera to record about 20 seconds of imagery as the arm, and Sellers, move along the shuttle’s wing leading edge.
Sellers, designated EV1 and wearing the spacesuit with red stripes, will meet EV2 Fossum, in the all-white suit, in Discovery’s payload bay. There they will set up the worksite for the repair tasks. A pallet with 12 reinforced carbon-carbon panels is pre-positioned in the payload bay. Eight are pre-damaged and will be the subject of the repair test. Two are blank, to be used as a work palette, and the last two are for further imaging by the infrared camera.
Sellers and Fossum will use a variety of tools and methods for the repair work demonstration including a space-certified caulk gun and a variety of spatulas to manipulate the test materials.
They hope to finish demonstrations on at least two of those samples. Then they’ll do a 60-second recording using the IR camera of two other damaged tiles. The camera is designed to capture temperature gradients that will indicate invisible damage.
If they have time, they may take additional photos of some shuttle panels and move the fixed grapple bar in the shuttle payload bay.
The spacewalkers will clean up the worksite and inspect their spacesuits. Then Fossum will ride the robotic arm back to the airlock, again taking video of the wing leading edge as he passes it. Sellers will make his own way back.
Pilot Mark Kelly will again serve as the intravehicular activities officer. Commander Steve Lindsey will oversee the shuttle systems and spacewalk operations.
While the shuttle crew is helping with the spacewalk, repacking of the multi-purpose logistics module Leonardo will continue. The Expedition 13 crew, Commander Pavel Vinogradov, and Flight Engineers Jeff Williams and Thomas Reiter, will put experiment results, unneeded equipment and garbage into Leonardo.
The STS-121 crew woke this morning at 12:08 a.m. to "I Believe I Can Fly," played for Wilson. The Expedition 13 crew was awakened 30 minutes later.

2006 Jul 12 - STS-121 MCC Status Report #17
Astronauts aboard Space Shuttle Discovery gathered valuable new data during the third spacewalk today as part of an ongoing evaluation of repairing a damaged orbiter.
Mission Specialists Piers Sellers and Mike Fossum began the spacewalk at 6:20 a.m. CDT and prepared a foot restraint on the end of the International Space Station’s Canadarm2. Sellers rode the arm, commanded by Mission Specialists Lisa Nowak and Stephanie Wilson, to the starboard wing of Discovery where he used an infrared camera to shoot 20 seconds of video of selected reinforced carbon carbon panels on the wing’s leading edge. Infrared imagery may aid in identifying damage on the inside of those panels.
Fossum translated to the aft of Discovery’s payload bay to join Sellers and help prepare a box containing 12 RCC sample panels for the EVA’s primary task of testing a repair material known as NOAX. Non-oxide adhesive experimental is a pre-ceramic polymer sealant containing carbon-silicon carbide powder, and is being evaluated for repairing damage to RCC panels.
Data gathered from tests on mission STS-114 last year indicated NOAX is most effective when applied while the temperature of an RCC panel is falling between 120° F and 30° F, so today’s spacewalkers were directed to apply NOAX to the pre-damaged RCC panels based on the temperatures of the panels. Over the course of almost two and a half hours, Sellers and Fossum completed three gouge repairs and two crack repairs with NOAX, and provided Mission Control a running dialogue describing the repair activity and how the NOAX responded. They also imaged four of the samples with the infrared camera, which Fossum also used to gather video of an area of Discovery’s port wing while riding Canadarm2 back to the airlock.
Near the end of the EVA, Mission Control added a task to the spacewalk. Since the spacewalkers were on schedule and had plenty of supplies, Sellers carried a Pistol Grip Tool to the Integrated Cargo Carrier in Discovery’s payload bay and removed the fixed grapple bar used during delivery of the Pump Module during the second spacewalk. He carried it to the S1 Truss where Fossum helped him install it on an ammonia tank inside that truss so that the tank can be moved on a later shuttle assembly mission.
Repressurization of Quest began at 1:31 p.m., completing a 7-hour, 11-minute spacewalk, the 68th in support of ISS assembly and maintenance. The cumulative duration of the three spacewalks on this mission is 21 hours and 29 minutes. Sellers’ total spacewalking time of 41:10 on six EVAs ranks him 4th among U.S. spacewalkers and 9th in the world all-time.
ISS Expedition 13 Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter concentrated on packing the Multipurpose Logistics Module today with returning experiment samples, unneeded hardware and trash. The Leonardo module is scheduled to be returned to Discovery’s payload bay on Friday.

2006 Jul 13 - STS-121 MCC Status Report #18
After eight days in space, three spacewalks and six days of cargo transfer, the Space Shuttle Discovery crew today gets a much deserved day off.
The crew woke at 12:08 a.m. CDT to "Charlie's Angels Theme Song." It was for the entire crew, from their training team.
Moments later, Texas A&M University yell leaders performed briefly for Mission Specialist Mike Fossum from Mission Control. Fossum is the first A&M undergraduate alum to fly in space.
Fossum is scheduled to receive a call from Texas Gov. Rick Perry, also an A&M graduate and former member of the Corps of Cadets, at 11:58 a.m. It will air on NASA Television.
Later in the day, Fossum and Mission Specialist Lisa Nowak will talk with representatives of MSNBC and FOX News Live. That interview, at 12:23 p.m., also will be seen on NASA-TV.
Fossum, Nowak and shuttle Commander Steven Lindsey, Pilot Mark Kelly and Mission Specialists Stephanie Wilson and Piers Sellers then have off duty time with only a few isolated tasks and exercise planned.
International Space Station Expedition 13 Commander Pavel Vinogradov, and Flight Engineers Jeff Williams and Thomas Reiter will talk at 3:13 a.m. with European Space Agency Astronaut Pedro Duque, a journalist, students and the operations manager at the Columbus Control Centre, in Cologne, Germany. At 8:09 a.m. the crew will talk with Russian journalists at Mission Control Moscow. Those events will air on NASA-TV and be replayed with interpretation at 9 a.m.

2006 Jul 14 - STS-121 MCC Status Report #20
It’s back to work for the Space Shuttle Discovery crew.
After a day off, the crew will spend much of today getting ready for their undocking from the International Space Station.
The crew woke at 12:19 a.m. CDT with the Aggie War Hymn performed by the Fighting Texas Aggie Band. It was for Mission Specialist Mike Fossum, a graduate of Texas A&M University.
The first activity of the day will be media interviews for most of the crew -- shuttle Pilot Mark Kelly, Mission Specialists Fossum, Lisa Nowak, Stephanie Wilson and Piers Sellers, and station Expedition 13 Commander Pavel Vinogradov and Flight Engineer Jeff Williams. Beginning at 3:03 a.m. they will talk with journalists from CNN, ABC News, NBC’s Today Show, and CBS News.
Meanwhile, shuttle Commander Steve Lindsey and station Flight Engineer Thomas Reiter will deactivate the multipurpose logistics module Leonardo and begin preparing for its move back to Discovery’s payload bay. Nowak and Wilson will use the station robotic arm to maneuver Leonardo, which has been packed with more than 4,000 pounds of experiment results, unneeded supplies and equipment from the station, to its place in the cargo bay.
The two, joined by Lindsey, will also use the arm with the boom extension to conduct a scheduled final inspection of the shuttle’s port wing to ensure it has not been damaged by orbital debris during the docked operations.
Throughout the day, the remainder of the crew will continue with final transfer of supplies and equipment from the shuttle’s middeck, organize the spacewalk tools and do other tasks to get ready for Discovery's undocking from the station on Saturday.

2006 Jul 14 - STS-121 MCC Status Report #21
Emptied of its cargo and refilled with returns, the Multipurpose Logistics Module Leonardo is back in the payload bay of Space Shuttle Discovery with just hours left before the orbiter undocks from the International Space Station and heads home.
First thing this morning Shuttle Commander Steve Lindsey and ISS Flight Engineer Thomas Reiter deactivated the cargo module, closed the hatch, and prepared it for removal from the Unity node. Just after 8:32 a.m. CDT Mission Specialists Lisa Nowak and Stephanie Wilson used the station robotic arm to uninstall Leonardo from ISS; the MPLM was reberthed in the shuttle payload bay at 10:00 a.m. CDT.
More than 7,400 pounds of cargo was delivered to ISS in the cargo module, and approximately 4,600 pounds of material including experiment samples, broken equipment and trash are now packed inside for return to Earth.
After the MPLM was returned to Discovery, Nowak and Wilson used the shuttle robot arm and the Orbiter Boom Sensor System to inspect the shuttle’s port wing. Similar to the pre-docking inspection on Flight Day 2, which was aimed at uncovering evidence of damage from debris at launch, this inspection looked for any signs of damage done by debris on orbit. None was found; inspection of the starboard wing and the shuttle’s nose cap will be done after undocking tomorrow, which is scheduled to occur at 5:08 a.m. CDT.
Early this morning, as Lindsey and Reiter worked at the MPLM, Nowak and Wilson joined Mission Specialists Mike Fossum and Piers Sellers, Pilot Mark Kelly, and ISS Commander Pavel Vinogradov and Flight Engineer Jeff Williams to discuss the mission in interviews with CNN, ABC, NBC and CBS.

2006 Jul 15 - STS-121 MCC Status Report #22
Today marks the final day of joint operations for the Space Shuttle Discovery and International Space Station crews.
After almost nine days together, Discovery is scheduled to undock from the station today at 5:08 a.m. CDT.
Discovery crew members were awakened at 12:08 a.m. by "Beautiful Day," performed by U2. It was for Discovery Pilot Mark Kelly, on undocking day.
After a few final equipment transfers and system configurations, all nine crew members will gather for a televised farewell ceremony at 2:38 a.m. Hatch closure between the station and shuttle will immediately follow.
After undocking, Kelly will perform the two separation burns to take Discovery away from the station.
About three hours after undocking, Commander Steve Lindsey and Mission Specialists Lisa Nowak and Mike Fossum will use the shuttle's robotic arm and the orbital boom sensor system to perform final inspections of the starboard wing. Then Kelly and Mission Specialist Stephanie Wilson will do the same on the shuttle nose.
Discovery will remain about 45 miles behind the station until the mission management team reviews survey results and clears Discovery for landing, scheduled for Monday at Kennedy Space Center.
The Expedition 13 crew will resume normal station operations. Once their shuttle counterparts have departed, they will conduct some routine maintenance and exercise onboard. Commander Pavel Vinogradov and Flight Engineer Thomas Reiter will conduct emergency drills training and Flight Engineer Jeff Williams will depressurize the pressurized mating adapter.

2006 Jul 15 - STS-121 MCC Status Report #23
The Space Shuttle Discovery is on its way home with six astronauts on board, one fewer than when it launched 11 days ago.
The delivery of European Space Agency astronaut Thomas Reiter to join Expedition 13 on the International Space Station was one of the major goals achieved on this second return to flight shuttle mission. Discovery is now aiming for an 8:14 a.m. CDT Monday landing at the Kennedy Space Center in Florida.
The shuttle astronauts said goodbye to Reiter and his crewmates, Station Commander Pavel Vinogradov and Flight Engineer Jeff Williams, and Commander Steve Lindsey and Pilot Mark Kelly reported the hatches between the two ships closed at 3:15 a.m. CDT. Astronauts Lisa Nowak and Stephanie Wilson completed a leak check in the docking vestibule while Mike Fossum and Piers Sellers installed a centerline camera in the hatch window.
With Kelly at the controls, Discovery released its grip on the station at 5:08 a.m. CDT and springs pushed the two ships apart. Kelly guided the shuttle away to a distance of 400 feet and fired thrusters to separate the vicinity of the complex. A second engine firing, 50 minutes after undocking while above and behind the station, set Discovery on course that now has it about 46 miles behind the station and opening the distance slowly. No other shuttle engine firings are planned before it fires its engines to begin the descent to Earth Monday morning.
After Discovery left the station, the shuttle crew used the robotic arm and boom sensors to thoroughly inspect the starboard wing and nose cap heat shield, looking for damage from orbital debris. A similar survey of the port wing was conducted yesterday. After the nose cap survey, the boom was berthed along the starboard sill of the payload bay and the robot arm was powered down.
Mission managers reviewing the latest heat shield inspections of Discovery have found no concerns so far, and the analysis is continuing. Discovery is planned to fire its engines to deorbit at 7:07 a.m. CDT Monday. That is the first of two opportunities for landing on Monday at Kennedy. A second opportunity begins with a deorbit engine firing at 8:43 a.m. CDT leading to a landing at 9:50 am. CDT.

2006 Jul 16 - STS-121 MCC Status Report #24
The Space Shuttle Discovery crew is scheduled for their last full day in space today, as they make their final preparations for deorbit and landing tomorrow.
Their day began at 12:18 a.m. with “Just Like Heaven,” by The Cure for Mission Specialist Piers Sellers. It was requested by his family.
At 3 a.m., Shuttle Commander Steve Lindsey, Pilot Mark Kelly and Entry Flight Engineer Lisa Nowak will do an hour-long flight control system checkout and fire the reaction control system jets. The checkout will let managers further assess the performance of one of the auxiliary power units. The APUs power flight control surfaces. Specialists had detected a small leak in the APU but have determined it is likely a nitrogen gas leak and should not affect re-entry.
Throughout the day, most of the crew members, including Mission Specialists Mike Fossum and Stephanie Wilson, will work on final clean up and stowage of the vehicle cabin area. All six crew members will participate in a deorbit briefing with the ground team as part of their final preparation for landing.
At 11:03 a.m. CDT, the STS-121 crew will participate in interviews with major television networks, including, ABC, CBS, CNN, FOX and NBC. That event will be televised on NASA television.
Mission managers continue to analyze images from the post-undocking inspection of Discovery's port wing and nose cone. Initial analysis indicated nothing amiss. A decision on whether to clear Discovery for landing is expected later today.
Discovery's deorbit burn is scheduled for 7:07 a.m. Monday, for an 8:14 a.m. CDT landing at Kennedy Space Center. A second opportunity would see a deorbit engine firing at 8:43 a.m. for a landing at 9:50 a.m.
Aboard the International Space Station, Expedition 13 Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter are enjoying an off-duty day after the intense activity during Discovery docked operations.

2006 Jul 17 - STS-121 MCC Status Report #26
A smooth landing by the Space Shuttle Discovery at the Kennedy Space Center this morning completed the second return to flight test mission and set the stage to resume assembly of the International Space Station later this summer.
Discovery and its crew of six astronauts touched down on runway 15 at the Shuttle Landing Facility at 8:15 a.m. CDT, completing 12 days, 18 hours and 38 minutes in space covering 5.3 million miles. They delivered European Space Agency astronaut Thomas Reiter to the station to join Expedition 13 and completed three spacewalks, one to restore the station’s rail car to full capability and two to develop shuttle repair techniques.
The crew was awakened at 12:08 a.m. CDT today with “The Astronaut” by Something Corporate, played for Commander Steve Lindsey as he prepared to complete his fourth shuttle flight. Returning to Earth aboard Discovery with Lindsey were Pilot Mark Kelly and Mission Specialists Mike Fossum, Lisa Nowak, Stephanie Wilson and Piers Sellers.
Discovery’s deorbit engines were fired for three minutes at 7:07 a.m. CDT above the Indian Ocean to begin the descent. The shuttle flew above Guatemala and Mexico, the Gulf of Mexico and the southwest Florida coast on the way to landing.

2006 Jul 22 - International Space Station Status Report: SS06-034
For the first time since early 2003, the International Space Station is home to three crew members.
European Space Agency astronaut Thomas Reiter joined Expedition 13 following Space Shuttle Discovery's mission earlier this month.
Reiter, who serves as the expedition flight engineer, Commander Pavel Vinogradov and Flight Engineer Jeff Williams got down to business. Their tasks this week included activating a new high-tech freezer; installing additional sound suppression devices; performing a functional check of a new oxygen generation system, which will become active next year; and preparing for the next spacewalk, set for just before 10 a.m. EDT on Aug. 3.
Discovery left behind about three tons of supplies, hardware and experiments as well as 175 gallons (660 liters) of water and 74 pounds (33 kilograms) of nitrogen, leaving the station in excellent condition to support the crew of three.
One of the most anticipated experiment racks, the Minus Eighty Laboratory Freezer for ISS, was activated. The freezer will allow biological and human research experiment samples to be stored until they are returned to Earth for evaluation.
The recent Discovery mission brought the new oxygen generation system and the freezer to the station. Status checks were performed this week on the newly installed oxygen system to prevent its internal valves from sticking over long periods of dormancy. Once it is activated, the device will augment the Russian Elektron oxygen-generation system in preparation for the further expansion of the station crew to six people.
The crew also began preparations for the next spacewalk. The spacewalk by Williams and Reiter will be conducted in U.S. spacesuits. The astronauts will deploy external experiments and prepare station truss components for future assembly work. Additional solar panels and electrical equipment will be delivered by the next two space shuttle missions, scheduled for late August and December. Spacewalk preparations included flushing cooling loops in the Quest airlock and the spacesuits and configuring airlock systems and tools. The astronauts also reviewed station robotic arm procedures.

2006 Jul 28 - International Space Station Status Report: SS06-035
The International Space Station's Expedition 13 crew members are a week away from their first U.S. spacewalk.
They spent much of this week preparing themselves and their gear, and they activated a new laboratory super deep-freezer.
Astronauts Jeff Williams and Thomas Reiter will leave the station's Quest airlock hatch at 9:55 a.m. EDT Thursday, Aug. 3, for a spacewalk that is scheduled for six hours, 20 minutes. Station Commander Pavel Vinogradov will serve as the spacewalk choreographer from inside the complex.
Williams and Reiter are both experienced spacewalkers. They will install a device to measure the electrical field around the station's exterior; replace a rotary joint motor controller and a computer for a radiator on the station's truss; deploy two experiments that expose samples of various materials to space for extended periods; and install various other hardware on the station.
To get ready, the crew prepared spacesuits and tools, conducted a dry run of egress and ingress procedures, and moved the station's Canadarm2 robotic arm into position. The arm's cameras will provide television views of the spacewalk.
This week the crew also began operations of the new Minus Eighty-degree Laboratory Freezer for ISS. The equipment can reach temperatures as low as minus 112 degrees Fahrenheit. Provided by the European Space Agency, the freezer was delivered on shuttle mission STS-121 earlier this month and is installed in the Destiny laboratory. It has 300 liters (about 79 gallons) of freezing and storage capacity in four compartments for experiment samples to preserve them for return to Earth.
On Tuesday, Russian flight controllers fired thrusters on the Progress supply ship docked to the aft end of the station to boost the station's altitude. They raised the complex to an orbit of 219 by 203 statute miles. The adjustment optimizes conditions for a docking by the Space Shuttle Atlantis, targeted for a launch window that begins Aug. 27, and by the station's next crew, Expedition 14, set for launch in mid-September on a Russian Soyuz rocket.

2006 Aug 4 - International Space Station Status Report: SS06-036
Space station crewmen Jeff Williams and Thomas Reiter worked quickly through scheduled spacewalk tasks Thursday, then completed three get-ahead jobs, or extra tasks, and were ready for more.
Mission Control assigned two more jobs, which the astronauts also completed.
Williams and Reiter wrapped up their productive 5-hour, 54-minute excursion and began repressurizing the Quest airlock at 3:58 p.m. EDT. The astronauts left the airlock in U.S. spacesuits at 9:04 a.m. EDT. Station Commander Pavel Vinogradov helped them with spacewalk preparations and getting into their suits. It was the first time in more than three years a third crewmember had been available for those tasks on the orbiting laboratory.
Williams, designated lead spacewalker, or EV1, wore the U.S. spacesuit with red stripes. Reiter, EV2, wore the all-white suit.
Astronaut Steve Bowen acted as spacewalk intravehicular officer and coached the astronauts from the International Space Station Flight Control Room in Houston's Mission Control Center. Williams and Reiter quickly got ahead of their timeline. First, they installed the Floating Potential Measurement Unit. The device measures the electrical potential of the station so procedures can be devised to minimize arcing hazards, or the jumping of current from a conductor to a ground, as the station grows.
Their second job was to install two containers for MISSE, the Materials on International Space Station Experiment. The suitcase-like containers are left open to evaluate the long-term effects of space exposure on a variety of materials. The idea is to identify optimal materials for use in future spacecraft. MISSE 3 went on one of the high-pressure tanks around the crew lock, while MISSE 4 was installed on Quest's outboard end.
The two astronauts then went on to separate jobs. Williams installed a controller for a thermal radiator rotary joint on the S1 truss, while Reiter replaced a computer on the truss.
Williams then began installing a starboard jumper and spool positioning device (SPD) on the S1 truss. Reiter inspected a radiator beam valve module SPD site where one device was already installed and installed an additional one. He then moved on to install a SPD on a port cooling line jumper. The jumpers are designed to improve the flow of ammonia through the radiators once that coolant is installed.
Williams began setup for the final major scheduled task, a test of an infrared camera designed to detect damage in a shuttle's reinforced carbon carbon (RCC) thermal protection. The camera highlights damage by showing variations in temperature between clean and damaged RCC test sections. Reiter operated the experiment while Williams went on to one of the additional tasks.
The first task was installation of a light on the truss railway handcart to help future spacewalkers. Williams then removed a malfunctioning GPS antenna. After Reiter finished the infrared camera experiment, he installed a vacuum system valve on the U.S. laboratory Destiny for future scientific experiments.
Mission control came up with additional tasks. Williams moved two articulating portable foot restraints to prepare for STS-115 spacewalks and then photographed a scratch on the airlock hatch. Reiter went to PMA1, a pressurized "corridor," to retrieve and inspect a ball stack, which holds hardware during spacewalks. The crew also had additional time throughout the spacewalk to photograph the worksites after their tasks were complete and then snap pictures of each other at the end. With no more quick tasks to add, the spacewalkers re-entered the airlock and closed the hatch early.

2006 Aug 11 - International Space Station Status Report: SS06-037
This week on the International Space Station crew members refurbished their exercise treadmill, prepared areas inside and out for an imminent expansion of their home and took a couple of special calls to discuss soccer and food in space.
Commander Pavel Vinogradov, Flight Engineer Jeff Williams and European Space Agency Astronaut Thomas Reiter are gearing up for the second space shuttle visit to the station during Expedition 13. The shuttle Atlantis, targeted to launch in a window that opens Aug. 27, will resume major orbital construction of the complex. During its mission, designated STS-115, Atlantis will deliver and install a 17.5-ton, bus-sized segment of the station's girder-like truss that includes another set of solar arrays, batteries and associated electronics.
The station crew started out the week with two days of standard maintenance work on the treadmill vibration isolation system, a special exercise treadmill located on the floor of the Zvezda living quarters module. Crews perform the maintenance task every six months to inspect the treadmill's components, replace worn items and install new bearings. The treadmill is a complex system that uses gyroscopes to stabilize itself and isolates the vibrations created by exercise from being transmitted to the station's structure, where they could disturb sensitive experiments. Extensive exercise is a daily regimen for all station crew members as one method of counteracting the effects of long exposure to weightlessness.
The crew had time set aside each day this week to pack up and prepare items that will be moved from the station to the shuttle during Atlantis' flight. In addition, ground controllers worked with the station's Canadarm2 robotic arm to prepare for the upcoming shuttle flight. On Thursday, they moved the arm to position cameras to view markings on the station used for a graphical computer alignment aid when new components are attached. That aid, called the space vision system, will be used during Atlantis' flight to help with the attachment of the new truss section.
On Friday, controllers moved the arm to perform an early checkout of its systems, ensuring it is ready for the shuttle mission.
The station crew greeted special guest calls this week. On Tuesday, the coach and players from the FC Barcelona soccer team talked with the crew as they visited NASA's Johnson Space Center prior to an exhibition game in Houston. Reiter, a soccer fan, showed the team a space soccer move during the call. On Thursday, the crew members spoke with Chef Emeril Lagasse about space food and their mission. Lagasse sent NASA several recipes that were prepared and delivered to the station aboard the last shuttle flight. The Expedition 13 crew tried the dishes this week.

2006 Aug 18 - International Space Station Status Report: SS06-038
The astronauts aboard the International Space Station spent much of their week preparing for the arrival of the Space Shuttle Atlantis, set for launch Aug. 27 on the STS-115 mission.
Commander Pavel Vinogradov, Flight Engineer and NASA Science Officer Jeff Williams and European Space Agency astronaut Thomas Reiter of Germany prepared for Atlantis to deliver a new section of the station's girder-like truss. During Atlantis' mission, astronauts will attach the new P3/P4 truss, a segment that includes a huge new set of solar arrays and a giant rotary joint that allows the arrays to track the sun. The mission will mark the resumption of station assembly by delivering the first large new component to the station since late 2002.
During the shuttle flight, Atlantis' crew members will perform three spacewalks to complete the installation and setup of the new segment. The spacewalks will begin from the station's Quest Airlock. Complex robotics work is involved as the 17.5-ton, bus-sized truss section is handed from the shuttle arm to the station arm for installation.
In preparation for Atlantis, the station crew trained on the robotic Canadarm2 and packed items for return to Earth on the shuttle. They also reviewed Atlantis' mission timeline and trained to photograph the shuttle's heat shield as the orbiter does a backflip while approaching the station. The crew also did several physiological and psychological tests and experiments designed to learn more about how humans react to long periods of weightlessness.
Early this week Williams worked with flight controllers and the Dynamic Onboard Ubiquitous Graphics program on robotic arm activities. The program simulates the arm's operation for training.
Williams moved the arm from a base on the U.S. Destiny Lab to a power and data grapple fixture on the mobile transporter, enabling the arm to work at different sites along the main truss railway. Subsequently, in an inchworm-like maneuver, the arm was moved to a different grapple fixture on the transporter and used to inspect the outboard end of the P1 truss, where the new segment will be attached. The crew also reviewed installation procedures for the new segment and Williams did spacesuit maintenance.
Throughout the week Vinogradov and Reiter worked on the Russian-German Plasma Crystal experiment. The experiment examines the behavior of tiny particles excited by high-frequency radio signals in a vacuum chamber and functions by itself most of the time. It requires a crew member to work with it, however, at some intervals during the day.
The EarthKam experiment was activated this week. EarthKam allows students to request photos from space of specific locations on Earth via email and later receive those photos electronically. The remote-controlled camera has been used since October 2001.

2006 Aug 25 - International Space Station Status Report: SS06-039
With the countdown clock ticking toward the launch of Space Shuttle Atlantis on the STS-115 mission, the International Space Station crew continues to prepare for visitors.
Commander Pavel Vinogradov, Flight Engineer, NASA Science Officer Jeff Williams and European Space Agency astronaut Thomas Reiter of Germany are ready for Atlantis to deliver a new section of the station's girder-like truss. Atlantis is set for launch on Sunday, which would result in docking with the station on Tuesday. During Atlantis' mission, astronauts will attach the new P3/P4 truss, a segment that includes a huge new set of solar arrays and a giant rotary joint to allow them to track the sun.
To prepare for Atlantis' visit, the station crew members packed items that will be returned to Earth on the shuttle. They also reviewed spacewalk plans, talked with the shuttle crew in a long-distance conference and trained to photograph the shuttle's heat shield as Atlantis does a backflip while approaching the station.
Flight controllers tested the operation of a U.S. air scrubbing system in advance. The Carbon Dioxide Removal Assembly, or CDRA, was turned on for an extended period to test its capability to remove carbon dioxide from the air. The CDRA augments the Russian air scrubber, Vozdukh, which was turned off during the test. Engineers are continuing to evaluate data from the CDRA operations.
The station was raised 2.5 miles by firing the ISS Progress 21 engines Wednesday. The boost places the complex at the optimum position for Atlantis' rendezvous and docking. It also puts the station at the optimum altitude for the launch of the next station resident crew, Expedition 14, from Kazakhstan in September.
Williams replaced filters in part of the station's cooling system. The used filters will be returned to Earth for engineering analysis to confirm their success at removing fine particles from water in coolant lines.
Williams completed runs of the Dust and Aerosol Measurement Feasibility Test, or DAFT experiment. DAFT is testing the effectiveness of a commercial hand-held air quality monitor called P-Trak that counts ultra-fine dust particles in microgravity. The study provides data that may help in the design of fire detection systems on future spacecraft. Its data also may prove useful for fire detection hardware in extreme environments on Earth, such as submarines or underwater laboratories.
The station crew continued with the set-up and check-out of the European Modular Cultivation System (EMCS) that was delivered on STS-121. This experiment system contains a centrifuge that can subject a wide range of small plant and animal experiments to partial gravity conditions.
The first experiment that will be performed in EMCS is the Analysis of a Novel Sensory Mechanism in Root Phototropism, called Tropi, which seeks to identify the genes responsible for successful plant growth in microgravity. The experiment studies mustard seeds.
Vinogradov and Reiter participated in European Space Agency science experiments that test the cardiovascular system's response to microgravity for long durations.

2006 Sep 2 - International Space Station Status Report: SS06-040
With the launch of Space Shuttle Atlantis delayed, activities for the International Space Station crew were adjusted.
The crew initially expected to greet Atlantis' crew this week. But the shuttle is set to launch Sept. 6 on mission STS-115 to bring a new truss section to the station, complete with a second set of 240-foot solar wings.
The mission was originally planned to launch Aug. 27. It was postponed first to check possible lightning damage and then due to Tropical Storm Ernesto. The delay gave Commander Pavel Vinogradov, Flight Engineer NASA Science Officer Jeff Williams and European Space Agency astronaut Thomas Reiter of Germany more time to prepare for Atlantis' mission.
The crew packed items that will be returned to Earth and reviewed plans for the shuttle flight's three spacewalks. They also conducted normal station maintenance, daily exercise sessions and scientific experiments.
Williams spent parts of three days this week working with a cosmic radiation study called the Anomalous Long-Term Effects in Astronauts' Central Nervous Systems. The experiment tracks cosmic radiation while monitoring brain activity and recording the subject's visual perceptions. Williams spent one orbit, about 90 minutes, floating prone with sensor blocks over and beside his head. The experiment's results may help develop ways to protect future space fliers from the effects of cosmic radiation.
Later in the week, Williams worked with the Capillary Flow Effects experiment, studying the dynamics of capillary flow in microgravity. Insight gained from the experiment may help in the developments of fluid transport systems for future spacecraft.
Other work included testing a seal the astronauts replaced on an experiment facility called the Microgravity Science Glovebox. The glovebox, in the U.S. laboratory Destiny, provides a contained environment for experiments involving fluid, flame or fumes.

2006 Sep 9 - STS-115 MCC Status Report #01
Atlantis launched into an almost clear Florida sky this morning for an 11-day mission that marks the return to assembly of the International Space Station.
Today marks the first time in almost four years that a major new space station component has been launched. Atlantis' mission begins a series of complex station expansion missions that will be among the most challenging spaceflights in history.
Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Heidemarie Stefanyshyn-Piper, Joe Tanner, Dan Burbank and Steve MacLean, a Canadian Space Agency astronaut, lifted off at 10:15 a.m. CDT. The launch followed a flawless countdown.
During the climb to orbit, Mission Control asked the crew to reconfigure a cooling system that apparently had ice build up. The reconfiguration cleared the system, called the Flash Evaporator System, and it operated normally. Temporary ice in that cooling unit is not uncommon and has occurred on previous missions.
Moments after main engine cutoff, 8.5 minutes after liftoff, Tanner and MacLean used handheld video and digital still cameras to document the external tank after it separated from the shuttle. That imagery, as well as imagery gathered by cameras in the shuttle’s umbilical well where the tank was connected, will be transmitted to the ground for review.
As Atlantis launched, the space station was 220 miles above the northern Atlantic Ocean, between Greenland and Iceland. Aboard the outpost are Expedition 13 Commander Pavel Vinogradov, a Russian cosmonaut; Flight Engineer and NASA Science Officer Jeff Williams; and Flight Engineer Thomas Reiter of the European Space Agency. They watched the launch via a live television transmission from Houston. Atlantis is set to dock to the complex at about 5:46 a.m. CDT Sept. 11.
Atlantis' crew will install the 17.5-ton, bus-sized P3/P4 integrated truss section to the station that includes a second set of solar arrays, batteries and associated electronics. The addition eventually will double the station’s capability to generate power from sunlight. The girder-like P3/P4 truss is 45 feet long.
Three spacewalks are planned to install the truss, deploy the arrays and prepare them for operation. Two teams, Tanner and Piper and Burbank and MacLean, will conduct the spacewalks.
During the mission, a thorough inspection will be performed in orbit of Atlantis' heat shield as has been done on the past two shuttle flights. Atlantis' time at the station could be extended by one or two days if needed to allow more time to complete those inspections or other operations. A second inspection of the heat shield is planned after Atlantis departs the station near the end of the flight to ensure it remains in good condition for landing.
When Atlantis arrives at the station, it will mark only the second time that as many as four of the station's five international partners have been represented onboard.
STS-115 is the 116th space shuttle mission and the 19th to visit the station. Atlantis is making its 27th flight and sixth trip to the station.
Atlantis’ crew begins an eight-hour sleep period at 4:15 p.m. CDT. The astronauts will awaken at 12:15 a.m. CDT Sunday to begin their first full day in orbit.

2006 Sep 12 - STS-115 MCC Status Report #06
It's installation day on the International Space Station. The Atlantis and Expedition 13 crews will attach the P3/P4 truss and do the first of three spacewalks by shuttle crew members.
Atlantis' astronauts were awakened at 11:15 p.m. CDT Monday with "My Friendly Epistle," a Ukrainian song by Taras Shevchenko. It was played for Heide Stefanyshyn-Piper.
She and fellow mission specialist Joe Tanner are scheduled to begin spacewalk 1 just after 4 a.m. They spent the night in the Quest Airlock, its pressure reduced to 10.2 psi. That was done to help purge nitrogen from their systems to avoid the possibility of formation of nitrogen bubbles in their blood during the spacewalk.
They are being helped in spacewalk preparations by Atlantis Commander Brent Jett, Mission Specialist Dan Burbank and station crewman Thomas Reiter.
At about 1 a.m., Canadian Space Agency Astronaut Steve MacLean and Expedition 13 Flight Engineer Jeff Williams used the station's Canadarm2 to begin the process of moving the truss to its new position at the end of the P1 truss segment. There four bolts will attach it.
Shortly after their spacewalk begins, Tanner and Piper will move to P3/P4. Tanner will connect power cables. Piper, working nearby, will release launch restraints on the Solar Array Blanket Box. The two will then work together and release other restraints on the Beta Gimbal Assembly, the structure between the truss electronics and the Solar Array Wings. Next, they will work on configurations of the Solar Alpha Rotary Joint, including the installation of drive lock assemblies.
Tanner’s final task will be connecting the electrical cables in the upper utility tray and removing two other circuit interrupt devices, which is necessary for the upcoming STS-116 mission. He and Piper will then return to the airlock.
Throughout the day, other crewmembers will support the spacewalk activities as well as work to transfer equipment and supplies between the two spacecraft and prepare for Wednesday's spacewalk by Burbank and MacLean.

2006 Sep 13 - STS-115 MCC Status Report #08
The Atlantis and Expedition 13 crews are getting ready for the second spacewalk of the STS-115 mission to the International Space Station.
They will continue preparations for activation of the P3/P4 truss segment attached to the station Tuesday.
Spacewalkers Dan Burbank and Steve MacLean will release and remove launch locks and launch restraints from the Solar Alpha Rotary Joint of the P4 truss. That joint will enable the new solar arrays to track the sun. The arrays are to be unfurled late today and early Thursday.
Burbank and MacLean spent the night in the Quest Airlock, as did Heidemarie Stefanyshyn-Piper and Joe Tanner before their Tuesday spacewalk, part of the campout pre-breathe protocol. Burbank and MacLean are preparing for their spacewalk, with help from shuttle Commander Brent Jett, Pilot Chris Ferguson and station Flight Engineer Thomas Reiter. The spacewalk is scheduled to begin at 4:15 a.m. CDT.
Tanner, now a veteran of six spacewalks, will serve as the intravehicular officer for this spacewalk. Piper will operate the station robotic arm to ensure video viewing during the spacewalk.
Because of the success of the first spacewalk, planners were able to add get-ahead tasks to today’s scheduled activities. Once their original tasks are complete, Burbank and MacLean also will prepare the P3 for the mobile transporter, part of a movable base system for the Canadarm2 to move along rails on the truss structure.
Depending on time available, they will remove a keel pin and drag link and stow them within the truss structure. They’ll also remove a Space Vision System target, rotate P1 and P3 mobile transporter and tether shuttle stops. They'll install a temporary rail stop for the Crew and Equipment Translation Aid cart.
Meanwhile, inside the orbiting laboratory, Expedition 13 Commander Pavel Vinogradov and NASA Science Officer Jeff Williams will continue with station operations tasks as well as transfer activities and preparations for their upcoming departure.
The two are scheduled to return to Earth aboard their Soyuz spacecraft Sept. 28. They will be replaced by Expedition 14 Commander Michael Lopez-Alegria and Cosmonaut Mikhail Tyurin, who are scheduled to launch from Baikonur Cosmodrome in Kazakhstan a little after 11 p.m. CDT Sept. 17. European Space Agency astronaut Thomas Reiter of Germany will remain on board the station and join the Expedition 14 crew.

2006 Sep 14 - STS-115 MCC Status Report #10
With several busy days including two successful spacewalks behind them, the Atlantis and International Space Station crews were looking forward to deployment of new station solar arrays and preparing for the mission's third spacewalk.
The ground teams completed the checkout of the Solar Alpha Rotary Joint (SARJ) early Thursday. The task had been interrupted Wednesday by a software glitch. Engineering teams developed a workaround, and flight controllers are working toward deployment of the 240-feet solar wings brought up with the P3/P4 truss.
The issue did cause replanning of the crews' schedule. As a result, crew activities today are subject to change.
Atlantis crewmembers were awakened at 11:15 p.m. CDT Wednesday by "Wipe Out," performed by the Surfaris. It was played for Pilot Chris Ferguson.
Thursday's agenda for Atlantis crewmembers, Commander Brent Jett, Pilot Ferguson and Mission Specialists Heidemarie Stefanyshyn-Piper, Joe Tanner, Dan Burbank and Steve MacLean, include executing a "double walk off" of the station's Canadarm 2 from the Mobile Base System to the Destiny Lab.
MacLean is scheduled to talk with Canadian Prime Minister Stephen Harper at 10:25 a.m. Also, Jett, station Expedition 13 Commander Pavel Vinogradov and E13 European Space Agency Astronaut Thomas Reiter were scheduled to talk with National Public Radio and CNN at 10:50 a.m.
While Ferguson does shuttle operations tasks, the rest of the crews, including station NASA Science Officer Jeff Williams, will review procedures for Friday's spacewalk, the third and final planned excursion outside during the STS-115 mission. Tanner and Piper will work on station truss segments to release the photovoltaic radiator restraints, deploy SARJ braces and install an external wireless TV transmission antenna.

2006 Sep 15 - STS-115 MCC Status Report #12
The Atlantis and International Space Station crews today will focus on the third and final spacewalk of the mission.
The STS-115 crew, Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Dan Burbank, Joe Tanner, Heide Stefanyshyn-Piper and Steve MacLean, is in its fourth day of joint operations with the station crew. Their Expedition 13 counterparts, Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter, will support the spacewalk activities as well as continued space station operations and maintenance.
Both crews awoke at 11:15 p.m. CDT to "Hotel California" performed by the Eagles and played for Tanner.
Tanner and Stefanyshyn-Piper will team up again for the spacewalk. While they were in the Quest airlock preparing for the spacewalk, a circuit-breaker-like remote power controller (RPC) tripped, causing loss of power to the airlock's depressurization pump. While flight controllers and engineers assessed the cause of the problem, the spacewalkers moved to the adjacent Unity module, while continuing to breathe oxygen through masks per their pre-spacewalk protocol.
The trip of the RPC was apparently due to a momentary spike in the electrical current of the depressurization pump. After assessing data to ensure the system had no short circuit, the breaker was reset and pump reactivated. Tanner and Stefanyshyn-Piper are scheduled to leave the Quest airlock at about 4:15 a.m. Once the spacewalk begins, the two will split up to perform the scheduled tasks for the spacewalk.
Tanner will install bolt retainers on the P6 Beta Gimbal Assembly, which helps to orient the pitch of the solar array wings. He’ll also use a new technique to attempt to re-engage a four-bar hinge lock that did not properly engage during STS-97.
Meanwhile, Stefanyshyn-Piper will retrieve the Materials on the International Space Station Experiment 5. The materials science experiment tests the effects of the space environment on prospective spacecraft materials.
The two will then prepare the photovoltaic radiator for deployment by removing launch hardware that was in place to protect it during the shuttle launch. Once that is done, other crewmembers can deploy that heat-dissipating radiator. Next the spacewalkers will replace an S-band antenna support assembly (SASA) on the Starboard 1 (S1) truss. They’ll also install a shroud on the failed SASA, which will be returned to Earth on a later mission.
Dividing again, Stefanyshyn-Piper will replace a baseband signal processor and transponder on S1 and Tanner will install a heat shield onto an antenna group interface tube to help overheating in this area during certain vehicle attitudes.
They’ll wrap up the spacewalk with two new tasks, installing a new external wireless television antenna and performing a Detailed Test Objective to assess infrared video of the wing leading edge. The spacewalk is scheduled to last 6.5 hours.
Once the spacewalk is completed, the mobile transporter, a movable platform that moves along the truss segments, will be relocated to a position on the newly arrived P3 truss to check out that worksite.

2006 Sep 16 - STS-115 MCC Status Report #14
The Space Shuttle Atlantis crew gets some well deserved time to relax today.
After the successful addition of new components to the International Space Station, five days of joint operations with the Expedition 13 crew and three successful spacewalks, they have some off-duty time.
They do have some post-spacewalk and transfer tasks scheduled.
The crew, Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Dan Burbank, Joe Tanner, Heide Stefanyshyn-Piper and Steve MacLean, got to sleep late. The wakeup music at 12:15 a.m. CDT was "Twelve Volt Man" by Jimmy Buffett. It was for Burbank.
After an off-duty morning, the STS-115 crew will be joined by the Expedition 13 crew of Commander Pavel Vinogradov, Flight Engineers Jeff Williams and Thomas Reiter for a crew photo. A joint crew press conference is scheduled for 7:35 a.m.
Jett, Burbank, Tanner, Stefanyshyn-Piper and MacLean will also participate in interviews with CBS News, NBC News and ABC News at 8:35 a.m.
Throughout the afternoon, the crew will work on various tasks including cleaning and configuration of the spacesuits, transfer of remaining cargo and supplies to the station and the removal of the REBA, Rechargeable EVA Battery Assembly.

2006 Sep 16 - STS-115 MCC Status Report #15
Astronauts on board Space Shuttle Atlantis today got a much deserved day off having completed three highly successful space walks that put the International Space Station back under construction.
After seven days in space, the STS-115 crew -- Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Dan Burbank, Joe Tanner, Heide Stefanyshyn-Piper and Steve MacLean -- got its first chance to sleep late. The crew then joined ISS Expedition 13 Commander Pavel Vinogradov, and Flight Engineers Jeff Williams and Thomas Reiter for a joint crew press conference.
During the morning, the crew also was interviewed by CBS News, NBC News and ABC News, completed transferring the last of the supplies and equipment to the station, including 90 pounds of oxygen, and removed the REBA, Rechargeable EVA Battery Assembly.
Atlantis will undock from the station at 7:50 a.m. CDT Sunday, circling the orbiting complex once as it departs to perform the first fly-around of the station in four years. The crew of STS-112 performed a partial fly-around to photo-document the station's exterior condition in Oct. 2002.
Tomorrow, all nine crew members will gather for a televised farewell ceremony at 4:43 a.m. CDT. Hatch closure between the station and shuttle will immediately follow.

2006 Sep 17 - STS-115 MCC Status Report #16
It's undocking day. The Space Shuttle Atlantis is scheduled to begin moving away from the International Space Station at 7:50 a.m. CDT.
Crew members will get a look at the results of their STS-115 mission, which resumed assembly of the station. They'll do a full fly-around, the first in four years, to photograph the station with its new truss segments and solar arrays.
Before undocking, the STS-115 crew -- Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Dan Burbank, Joe Tanner, Heide Stefanyshyn-Piper and Steve MacLean -- will say farewell to Expedition 13 -- Commander Pavel Vinogradov, and Flight Engineers Jeff Williams and Thomas Reiter -- about 5 a.m. before closing the hatches between the two vehicles.
Then, with Ferguson at the controls, Atlantis will slowly move away from the station. The fly-around is scheduled to start at about 8:15 a.m. Atlantis is to leave the area a little after 9:30 a.m.
Meanwhile, on the ground, preparations are under way for the launch of the next inhabitants of the station. The Expedition 14 crew, Commander Michael Lopez-Alegria and Flight Engineer Mikhail Tyurin, and spaceflight participant Anousheh Ansari, are scheduled to launch in their Soyuz TMA-9 spacecraft from the Baikonur Cosmodrome in Kazakhstan at 11:09 p.m. CDT. They are scheduled to dock with the orbital laboratory two days later.
The shuttle and station crews woke at 11:15 p.m. to "Danger Zone" by Kenny Loggins, played for Ferguson. In his reply, Ferguson thanked soon-to-retire STS-115 lead guidance, navigation and control flight controller Charles Alford for his 40 years of NASA service. The shuttle pilot also thanked all those in Mission Control for helping to make spaceflight possible.

2006 Sep 17 - STS-115 MCC Status Report #17
The Space Shuttle Atlantis left a space station today markedly different than the one to which it docked less than a week ago.
Atlantis undocked from the International Space Station at 7:50 a.m. CDT, completing six days, two hours and two minutes of joint operations with the station crew. As the shuttle departs, a new station crew is preparing to launch to the complex tonight from the Baikonur Cosmodrome, Kazakhstan.
Atlantis left the station with a new, second pair of 240-foot solar wings, attached to a new 17.5-ton section of truss with batteries, electronics and a giant rotating joint. The new solar arrays eventually will double the station's onboard power when their electrical systems are brought online during the next shuttle flight, planned for launch in December.
Atlantis is now aiming for a 4:57 a.m. CDT Wednesday landing at the Kennedy Space Center in Florida.
Meanwhile, the station's Expedition 14 crew -- Commander and NASA Science Officer Michael Lopez-Alegria, Flight Engineer Mikhail Tyurin and spaceflight participant Anoushheh Ansari -- are set to launch in their Soyuz TMA-9 spacecraft from Baikonur at 11:09 p.m. CDT. Lopez-Alegria and Tyurin will begin a six-month stay aboard the station when they dock to the complex on Wednesday. Ansari is visiting the station for eight days under a commercial agreement with the Russian Federal Space Agency.
After undocking, Atlantis' crew -- Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Dan Burbank, Joe Tanner, Heide Stefanyshyn-Piper and Steve MacLean -- got a breath-taking view of the station as the shuttle circled the complex. During their stay at the station, the shuttle crew conducted three spacewalks in four days to prepare the new components for operation.
As Atlantis performed a full fly-around of the station, the shuttle crew took photographs and video of the complex's new T-shaped solar array configuration. The station's truss now stretches 179 feet.
In addition to the new truss section and its arrays, the astronauts transferred 800 pounds of hardware and 1,043 pounds of water to the station in exchange for 1,084 pounds of returning hardware. They also placed about 200 pounds of launch locks, restraints and other unneeded hardware on ISS Progress 21 for disposal.
The shuttle astronauts spent five days, 21 hours and 57 minutes with hatches open to the station working with the station's Expedition 13 crew -- Commander Pavel Vinogradov, and Flight Engineers Jeff Williams and Thomas Reiter. The hatches were shut for Atlantis' undoccking at 5:27 a.m. CDT. Vinogradov, Williams and Ansari will land in a Soyuz spacecraft in Kazakhstan Sept. 29. Vinogradov and Williams have been in orbit since March.
On Monday, the shuttle crew will use the ship’s robotic arm to grapple the boom sensor system once more to conduct a final inspection of the heat shielding on Atlantis’ wings and nose cap. The additional late inspecting ensures the areas still are in good shape for entry into the atmosphere and landing.
Atlantis' crew begins their sleep period at 2:15 p.m. CDT and will awaken at 10:15 p.m. CDT.

The International Space Station is a busy place these days. Sunday saw the departure of the space shuttle visitors who had been working from the orbiting complex the past six days with a 7:50 a.m. CDT undocking of Atlantis. Hours later, three more explorers launched toward the station in a Soyuz spacecraft.
Expedition 14 Commander Michael Lopez-Alegria, Soyuz Commander Mikhail Tyurin and spaceflight participant Anousheh Ansari lifted off at 11:09 p.m. CDT Sunday from the Baikonur Cosmodrome in Kazakhstan.
They are expected to arrive at the station early Wednesday. They will begin nearly nine days of handover activity as Lopez-Alegria and Tyurin prepare for their own six-month stay. Ansari, visiting the station as part of a commercial agreement with the Russian Federal Space Agency, will return to Earth with Expedition 13 Commander Pavel Vinogradov and Flight Engineer Jeff Williams. European Space Agency Astronaut Thomas Reiter will remain onboard as part of Expedition 14.
Traveling about 50 miles behind the station, the Atlantis crew -- Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Dan Burbank, Joe Tanner, Heide Stefanyshyn-Piper and Steve MacLean -- woke at 10:15 p.m. to “Rocky Mountain High.” It was played for Tanner.
The crew will focus today on the final inspection of the shuttle’s reinforced-carbon-carbon surfaces on the wing leading edges and nose cap. Ferguson, Burbank and MacLean will use the shuttle’s robotic arm to get a final look at those areas, ensuring no critical damage may have occurred since their arrival in space. Aside from a few other minor tasks it will be a light-duty day. Atlantis is prepared for its landing Wednesday at the Kennedy Space Center in Florida.

2006 Sep 18 - STS-115 MCC Status Report #19
The crew of the International Space Station worked through an emergency procedure this morning after an oxygen generation unit apparently overheated.
The overheating is believed to have melted a rubber seal, causing a small amount of smoke, a strong odor and possibly releasing a small amount of a chemical irritant.
Aboard the station are Expedition 13 Commander Pavel Vinogradov, Flight Engineer and NASA Science Officer Jeff Williams and Flight Engineer Thomas Reiter of the European Space Agency. At the time of the problem, Vinogradov was working with the Russian Elektron oxygen generator, a device that recycles wastewater on the station into oxygen for the cabin air. The Elektron had been shut off for nine days as planned during the joint operations by the station and the Space Shuttle Atlantis.
At the request of Russian flight controllers, Vinogradov attempted to restart the unit at about 2 a.m. CDT. The Elektron operated only briefly before shutting down. Several subsequent attempts were made to restart the device in various modes. Just before 6 a.m. CDT, Vinogradov restarted the unit again after it had shut down.
A few minutes later, as the station was out of communications with the ground, Vinogradov noted the Elektron overheating, light smoke and a bad odor. When the station moved into communications, at about 6:16 a.m. CDT, Mission Control asked the crew to manually initiate a fire alarm onboard to allow software to automatically shut down ventilation fans between the station modules. Flight controllers also checked for contaminants in the cabin air and found only low levels that posed no danger to the crew. However, the crew was asked to briefly don surgical masks, goggles and gloves to protect against possible irritation by a chemical used in the Elektron, potassium hydroxide, that may have leaked.
Vinogradov reported that a small amount of clear liquid had leaked from an apparently damaged seal on the Elektron and cleaned it up, sealing it in airtight bags. Within an hour, the crew had powered back on all station ventilation equipment and had returned to working on normal activities.
The incident will not affect plans to undock a Progress cargo craft from the station tonight and the docking of the next station crew with the complex, set for 12:24 a.m. CDT on Wednesday, Sept. 20.
Expedition 14 Commander Michael Lopez-Alegria, Soyuz Commander Mikhail Tyurin and Spaceflight Participant Anousheh Ansari lifted off at 11:09 p.m. CDT Sunday from the Baikonur Cosmodrome in Kazakhstan bound for the station. Their Soyuz spacecraft is in excellent condition.
Meanwhile, the crew of the Space Shuttle Atlantis -- Commander Brent Jett, Pilot Chris Ferguson and Mission Specialists Joe Tanner, Dan Burbank, Heide Stefanyshyn-Piper and Steve MacLean -- are continuing preparations for a return to Earth. The crew completed a late inspection of the heat shielding on the nose and wings of the shuttle today using a laser scanning system. They are scheduled to land at the Kennedy Space Center at 4:59 a.m. CDT Wednesday. They began a sleep period at 1:15 p.m. CDT and awaken at 9:15 p.m. CDT for what is planned to be their final full day in orbit.

A space-age conference call linked three orbiting crews early Tuesday.
Three people aboard the Soyuz TMA 9 talked with the six Atlantis astronauts and the three-man Expedition 13 crew aboard the International Space Station.
The linkup was managed through Houston's Mission Control Center. The 12 people on the three very different space vehicles began their chat about 2 a.m. CDT.
"It's a little crowded in the sky today," said Jeff Williams from the station. "We look forward to having you guys on board," he told the Soyuz crew. "We'll see you back on Earth sometime soon," Atlantis Commander Brent Jett told Expedition 13.
The Expedition 13 crew, Commander Pavel Vinogradov and Flight Engineers Williams and Thomas Reiter, is awaiting the arrival of Expedition 14, Commander Michael Lopez-Alegria and Flight Engineer Mikhail Tyurin. With them is spaceflight participant Anousheh Ansari. They are scheduled to dock with the station at 12:24 a.m. Wednesday.
Atlantis' crew, Jett, Pilot Chris Ferguson and Mission Specialists Joe Tanner, Dan Burbank, Heide Stefanyshyn-Piper and Steve MacLean, is getting ready to come home, with a landing scheduled for Kennedy Space Center at 4:59 a.m. CDT Wednesday.
They were awakened at 9:15 p.m. Monday with “Ne Partez Pas Sans Moi” (Don’t Leave Without Me) for MacLean, performed by fellow Canadian Celine Dion. They checked out Atlantis' flight control surfaces and later tested reaction control system thrusters. Today they'll continue stowage activities and other preparations for their landing.
The unpiloted Progress 21 cargo spacecraft with its load of station discards undocked from the orbiting laboratory at about 7:30 p.m. Monday. It re-entered the atmosphere and was incinerated over the Pacific Ocean about 11 p.m.

2006 Sep 19 - STS-115 MCC Status Report #21
Space Shuttle managers today decided to extend Atlantis' stay in space to allow for additional inspections of the spacecraft to be performed.
The decision to pursue additional inspections was made this morning after video from cameras aboard the shuttle showed a piece of debris in close proximity to the vehicle.
Also, the weather forecast for a landing on Wednesday had called for poor conditions, and Atlantis has plentiful supplies aboard to allow multiple landing attempts as late as Saturday. Atlantis is now aimed toward a landing on Thursday at NASA's Kennedy Space Center, Florida.
Engineers are concerned the debris seen could be something that came loose from Atlantis. They will use the extra time to verify the shuttle is in good shape for the trip home.
Atlantis' crew -- Commander Brent Jett, Pilot Chris Ferguson and mission specialists Joe Tanner, Dan Burbank, Heidemarie Stefanyshyn-Piper and Canadian Space Agency astronaut Steve MacLean -- will use the shuttle's robotic arm on Wednesday to inspect the spacecraft. The crew began a sleep period at 12:45 p.m. CDT today and will awaken at 8:45 p.m. CDT. Before going to sleep, the crew positioned the arm above the payload bay, and Mission Control has used its cameras to survey the top side of the shuttle. The cameras on the robotic arm will later be used by the crew to inspect areas on the underside of Atlantis.
Atlantis' primary landing opportunity to Kennedy on Thursday begins with a deorbit engine firing at 4:14 am. CDT and culminates in a touchdown at 5:22 a.m. CDT.
Meanwhile, the International Space Station's next crew, Expedition 14 Commander Mike Lopez-Alegria and Soyuz Commander and Flight Engineer Mikhail Tyurin are closing in on the complex. With them is Spaceflight Participant Anousheh Ansari, a U.S. businesswoman who will spend eight days on the station under a commercial agreement with the Russian Federal Space Agency. They will dock their Soyuz spacecraft to the station at 12:24 a.m. CDT Wednesday.
Aboard the station, Expedition 13 Commander Pavel Vinogradov, Flight Engineer and NASA Science Officer Jeff Williams and Flight Engineer Thomas Reiter, a European Space Agency astronaut, will open hatches to greet their new arrivals at 3:10 a.m. CDT Wednesday. The station crew spent some additional time earlier today gathering data on the Elektron oxygen generating system's overheating malfunction. Russian engineers are continuing to evaluate the system's malfunction and future repairs. Repair work is not planned to be performed while the crew hands over operations of the complex to Expedition 14. Oxygen supplies on the station are plentiful, and the cabin air will be refreshed using oxygen canisters and tanks until the Elektron is repaired.

The Space Shuttle Atlantis crew began another survey of the spacecraft's heat shield late Tuesday after mission managers decided the orbiter would spend another day in space.
That decision was made after cameras detected a piece of debris near the shuttle early Tuesday.
The survey is to make sure Atlantis is ready for re-entry and its landing at the Kennedy Space Center. Florida weather also was questionable for a Wednesday landing.
The crew woke up at 8:45 p.m. CDT Tuesday to “Beautiful Day” by U2, played for Heide Stefanyshyn-Piper. After some routine personal time, they began the survey at about 11:30 p.m. Pilot Chris Ferguson and Mission Specialists Dan Burbank and Steve MacLean are using the shuttle's robotic arm and its cameras to get a full look at Atlantis' thermal protection system. The task could take up to five hours.
Specialists on the ground will review the imagery as it is available and determine if a more detailed survey using the 50-foot orbiter boom sensor system (OBSS) is warranted. The OBSS survey, if needed, would take another three hours.
Atlantis Commander Brent Jett and Mission Specialists Joe Tanner and Piper will help as needed with the survey and continue with other tasks including waste and water dump, exercise, downlink of imagery and stowage of the Payload General Support Computer.
Atlantis' next landing opportunity is Thursday with a deorbit engine firing at 4:14 a.m. CDT and touchdown at 5:22 a.m. Atlantis has enough supplies to stay in orbit until Saturday.
Early Wednesday International Space Station Expedition 14 Commander Michael Lopez-Alegria and Flight Engineer Mikhail Tyurin, and spaceflight participant Anousheh Ansari arrived at the orbiting laboratory. Their Soyuz docked at 12:21 a.m. The hatch opening and welcoming ceremony with the Expedition 13 crew, Commander Pavel Vinogradov and Flight Engineers Jeff Williams and Thomas Reiter, is scheduled for 3:30 a.m.

2006 Sep 20 - STS-115 MCC Status Report #23
Managers today cleared the Space Shuttle Atlantis for a return to Earth on Thursday following a day of inspections of the spacecraft's exterior.
Atlantis is now aimed toward a landing that will begin with a deorbit engine firing at 4:14 a.m. CDT and culminate in a touchdown at 5:21 a.m. CDT at the Kennedy Space Center, Fla. The astronauts would close the shuttle's payload bay doors in preparation for the landing at about 1:44 a.m. CDT. A backup opportunity for landing would begin with a deorbit engine firing by the shuttle at 5:51 a.m. CDT leading to a touchdown at 6:57 a.m. CDT.
The weather is forecast to be acceptable for landing at Kennedy, with few clouds and light winds.
The astronauts performed televised inspections early this morning of the shuttle's heat shield, nose, tail, payload bay, wings and other areas using the robotic arm and a boom extension. Engineers found no issues of concern during the survey.
A shim and a spacer piece that had been protruding from thermal tiles on Atlantis earlier in the mission were found to be missing during the inspection. But it is not known whether one of them was the item seen floating near Atlantis in video on Tuesday. Atlantis' astronauts began a sleep period at 12:45 p.m. CDT. They will awaken at 8:45 p.m. CDT.
