• 2001 Aug 10 - STS-105 Mission Status Report #01 

  After a one-day delay because of weather, Space Shuttle Discovery blasted off this afternoon, carrying a crew of four and three new residents to the International Space Station.

  As the station sailed over the Pacific Ocean southwest of the border between Mexico and Guatemala, Discovery rocketed away from Launch Pad 39-A at the Kennedy Space Center at 4:10 p.m. Central time en route to a rendezvous and docking Sunday afternoon.

  Aboard Discovery were Commander Scott Horowitz, Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan Barry along with Expedition Three Commander Frank Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin. They will replace the Expedition Two crew, Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms, who were wrapping up their 155th day in space at the time of Discovery's launch.

  Less than nine minutes after beginning its journey, Discovery settled into its preliminary orbit as the crew prepared to open the ship's payload bay doors prior to receiving the green light to begin orbital operations. This is the fifth shuttle mission of the year.

  Discovery's crew will spend the next few hours unpacking equipment, setting up computers and conducting the first in a series of engine firings to refine the shuttle's orbit as it heads for the station. The crew will begin an eight-hour sleep period shortly after 11 p.m. and will be awakened at 7:15 a.m. Saturday for its first full day in orbit. That day will be devoted to preparations for Sunday's rendezvous and docking and eight days of joint operations with the Expedition Two crew, highlighted by the official transfer of command of the station from Usachev to Culbertson.

  Aboard the station, Usachev, Voss and Helms have spent most of the past couple of weeks packing gear for the trip home aboard Discovery, and tidying up for the arrival of visitors about 1:30 p.m. Sunday.

  Discovery is in an orbit inclined 51.6 degrees to either side of the Equator with all of its systems operating normally.

• 2001 Aug 11 - STS-105 Mission Status Report #02 

  The seven crewmembers aboard Discovery were awakened shortly after 7 a.m. Saturday for their first full day in space, a day of pursuit and preparation for a Sunday rendezvous and docking with the International Space Station (ISS).

  Discovery's astronauts and cosmonauts, Commander Scott Horowitz, Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan Barry, and Expedition Three Commander Frank Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin, were awakened to "Back in the Saddle Again" by Gene Autry. It was played for Culbertson, making his third flight into space, eight years after he last flew.

  At the time the crew was awakened, some 8000 statute miles separated Discovery from the ISS. A second firing of Discovery's orbital maneuvering systems engines is scheduled for early in the crew's day today to further adjust its orbit in preparation for rendezvous and docking with the station. Also scheduled today are the checkout of spacesuits to be worn by Barry and Forrester during two spacewalks next week, the preparation of rendezvous and navigation tools and a test of the shuttle's robotic arm, all routine work on the day before docking. Crewmembers also will perform a camera survey of Discovery's cargo bay with arm-mounted cameras.

  Discovery is scheduled to linkup to the ISS tomorrow at 1:37 p.m. Central time as the two spacecraft fly over the Indian Ocean northwest of Australia, just south of the Indonesian island of Jawa.

  The major objective of the STS-105 mission of Discovery is the swapout of the new resident Station crew, led by Culbertson, with the Expedition Two crew, Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms, who have been aboard the Station more than five months. They are to return to Earth aboard Discovery on August 22.

  Discovery also is bringing equipment, supplies and scientific experiments to the Station. Almost 7,000 pounds of that cargo is in Leonardo, the Italian-built Multipurpose Logistics Module in Discovery's cargo bay. Once that is transferred to the station, Leonardo will be packed with other equipment, unused items and trash for return to Earth.

  During their eight days docked to the station, Discovery Mission Specialists Barry and Forrester will perform two spacewalks. On the first, next Thursday, they will install a device called an Early Ammonia Servicer on the Station. It contains spare ammonia that could be used to cool Station systems should it be needed. During the second spacewalk, two days later, they will install heater cables for the station's large S0 truss segment, which will be delivered on a future mission, as well as handrails.

  Discovery is orbiting the Earth in excellent shape with no issues being worked by the flight control team.

• 2001 Aug 11 - STS-105 Mission Status Report #03 

  The seven crewmembers aboard Discovery, including the future residents of the International Space Station (ISS), spent their first full day in orbit today preparing for their arrival tomorrow at the orbital outpost.

  Commander Scott Horowitz, Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan Barry, along with Expedition Three Commander Frank Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin, checked out Shuttle systems, navigational tools and docking hardware in advance of Discovery's planned linkup to the ISS.

  The docking is scheduled to occur Sunday at 1:38 p.m. Central time over the Indian Ocean northwest of Australia, just south of the Indonesian island of Jawa.

  Forrester and Horowitz powered up, unfurled and checked out Discovery's 50-foot long robotic arm, which will be used by Forrester to move the Leonardo cargo module from Discovery's payload bay to the ISS for the transfer of food and supplies, and by Horowitz to transport Barry and Forrester around the Station during their two spacewalks next week.

  In addition, Barry and Forrester tested the devices they will use tomorrow to measure Discovery's distance from the ISS and its rate of closure on the complex during the terminal phase of the Shuttle's approach to the Station. Discovery's docking mechanism was also checked out and its outer docking ring extended to ensure it is ready for tomorrow's capture of the ISS docking port on the forward end of the Station's Destiny laboratory module.

  Next week, Barry and Forrester will test the spacesuits they will wear during their two excursions outside Discovery to attach a spare cooling reservoir to the ISS and to hook up heating cables for a large truss structure that will be mounted to the Station next year.

  The crew enjoyed a few hours of spare time this afternoon to relax as they wound down for the start of an eight-hour sleep period just after 9 p.m. Central time tonight.

  Aboard the ISS, Expedition Two Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms spent the day packing up personal items and preparing Station systems for tomorrow's arrival of their replacements, Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin. This was the 156th day in space for the current occupants of the ISS.

  The exchange of crew members on the Station will occur on Monday, although formal command of the Station will not be transferred from Usachev to Culbertson until a few hours before Discovery's undocking on August 20.

  Almost 7,000 pounds of food, supplies and personal items for the Expedition Three crew are housed in Leonardo, the Italian-built Multi-Purpose Logistics Module (MPLM).

  Once the module is transferred to the Station and unpacked, it will be filled with equipment no longer needed on the ISS, including Expedition Two crew clothing and trash for return to Earth.

  Discovery is orbiting the Earth in excellent shape with no issues being worked by the flight control team.

• 2001 Aug 12 - STS-105 Mission Status Report #04 

  The crew of Discovery, trailing the International Space Station by less than 2,000 statute miles, was awakened at 5:10 a.m. Central time to the sounds of "The White Eagle," a traditional Russian folk song played for Expedition Three Pilot Vladimir Dezhurov. Dezhurov and his crewmates, Expedition Three Commander Frank Culbertson and Flight Engineer Mikhail Tyurin are just hours from reaching their new home aboard the International Space Station (ISS).

  Discovery Commander Scott Horowitz, Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan Barry, along with the Expedition Three crew, will begin rendezvous operations a little before 9 a.m. today. The shuttle will begin a final approach to the station from a point about 9 miles behind the outpost with the last major rendezvous maneuver scheduled at around 11:15 a.m.

  With Discovery about 600 feet directly below the station, Horowitz will fly the shuttle in a quarter circle to a point in front of the complex. From there he will very slowly and precisely maneuver Discovery toward the station, pausing about 30 feet from the ISS to precisely align the docking mechanisms of the two craft.

  Docking is expected to occur at 1:38 p.m. over the Indian Ocean just south of the Indonesian island of Jawa. The hatches separating the two spacecraft are to be opened around 3:30 p.m. allowing the current station residents, Expedition Two Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms to greet their replacements and the Discovery astronauts who will bring them home after more than five months in space.

  ISS flight controllers are expected to ask the Expedition Two crew on Wednesday to try to reboot one of three command and control computers which experienced a hard drive problem last week and which has been put in standby mode with no impact to station operations. If the reboot does not recover the use of the hard drive, the crew may be asked to replace a component in the computer with a spare being brought to the station on Discovery. Two other command and control computers, a prime and a backup, are working perfectly in support of U.S. segment systems.

  Discovery is orbiting the Earth every 90 minutes in good shape in pursuit of the International Space Station.

• 2001 Aug 12 - STS-105 Mission Status Report #05 

  Discovery Commander Scott Horowitz, with the assistance of Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan Barry, carefully guided the Shuttle to a linkup with the ISS at 1:42 p.m. Central time as the two craft sailed 240 miles above northwestern Australia. On board Discovery were the new Station Commander Frank Culbertson, and his Expedition Three crewmates, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin.

  Expedition Two Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms looked on from the station's Destiny laboratory as Discovery arrived this afternoon, then worked in concert with their Shuttle counterparts to ensure a tight seal and a firm mate between the two vehicles.

  At 3:41 p.m., hatches finally swung open between Discovery and the ISS, and the two crews greeted one another. First aboard the station was Culbertson to survey his home for the next four months. Within minutes, all ten astronauts and cosmonauts had shared greetings before settling in for a station safety briefing conducted by Usachev.

  Monday the crews will attach the Leonardo cargo carrier to the station at about 9:30 a.m. and begin unloading its supplies.

  Just prior to this operation, the two station crews will systematically begin the process of handing over command from Expedition Two to Expedition Three. The plan is for Culbertson and Helms to remove her form-fitting seat liner from the Soyuz spacecraft and replace it with Culbertson's at about 7 a.m. Two hours later at about 9 a.m., Dezhurov and Usachev will do the same followed at 12:30 p.m. by the seat liner swap of Tyurin and Voss. The Soyuz is used as a return vehicle in the event of a problem on the station.

  Crew sleep is scheduled for about 8 tonight with a musical wakeup call from Mission Control at 5:10 a.m. Monday.

  The station and shuttle complex is orbiting the Earth every 92 minutes in good shape.

• 2001 Aug 13 - STS-105 Mission Status Report #06 

  The crewmembers aboard the Discovery / International Space Station complex were awakened shortly before 4:30 a.m. Central time today to the sounds of the overture from "The Barber of Seville" by Rossini, a tribute to Expedition Three Flight Engineer Mikhail Tyurin, who along with Commander Frank Culbertson and Pilot Vladimir Dezhurov, will move over to the ISS today to take up residency.

  Once they swap out their custom-made Soyuz capsule seat liners with those belonging to Expedition Two Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms, Culbertson, Dezhurov and Tyurin will become the third trio of residents to inhabit the complex, while Usachev, Voss and Helms become members of Discovery's crew.

  The Soyuz serves as a crew return vehicle in the unlikely event it should become necessary to leave the station.

  Official handover of command of the ISS from Usachev to Culbertson will take place on August 20, shortly before Discovery undocks from the Station.

  After the crew transfer is complete, the oncoming ISS residents will begin a comprehensive handover with their departing counterparts, receiving briefings on Station systems, the current configuration of hardware and computers and procedures they will employ during their first days on board the outpost.

  Mission Specialist Pat Forrester will use Discovery's robot arm to move the Italian-built Leonardo cargo module from the shuttle's payload bay to the nadir docking port of the Station's Unity module so it can be unloaded of more than three tons of supplies and equipment for the newly arrived Expedition Three crew. Leonardo also contains racks of scientific experiments which will greatly enhance the scientific research on board the ISS over the next few months. Leonardo will be installed on the Station late this morning.

  Other equipment will be transferred throughout the day from Discovery's middeck lockers to the ISS as the crews work in concert to set the stage for the Expedition Three mission.

  The joined spacecraft are orbiting at an average altitude of about 244 statute miles, completing an orbit of the Earth every 90 minutes. Both craft are in good condition.

• 2001 Aug 13 - STS-105 Mission Status Report #07 

  The International Space Station's third resident crew officially took control of the complex at 2:15 p.m. CDT today, when confirmation was given by the new station commander that all transfer activities associated with the custom-made Soyuz capsule seat liners had been completed and leak checks on their Russian Sokol space suits was verified.

  That marked the end of the Expedition Two crew's stay on the station at 148 days since it took over for the first resident crew on March 18. By the time the Expedition Two crew lands aboard Discovery next week, Yury Usachev, Jim Voss and Susan Helms will have spent 163 days aboard the station and 167 days in space.

  The official ceremonial handover of command of the ISS from Usachev to Culbertson will take place Aug. 20, shortly before Discovery undocks from the Station.

  The systematic swap of the seat liners and space suits occurred in and around the installation of the Leonardo Multipurpose Pressurized Logistics Module onto the station. Leonardo is one of three cargo supply vessels designed to deliver food, clothing, experiments and other hardware to and from the station throughout its orbital life. It was attached to the station at 10:55 a.m. CDT and its hatch opened at 2:47 p.m. CDT.

  Now that the official crew transfer is complete, the Expedition Three crew of Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin will begin a comprehensive handover with their departing counterparts, receiving briefings on station systems, the current configuration of hardware and computers and procedures they will employ during their first days on board the outpost.

  The crew will be awakened at 4:10 a.m. CDT Tuesday to continue the unloading of more than three tons of supplies and experiments from Leonardo. At 2 p.m. CDT Tuesday, the two station commanders, Culbertson and Usachev, will take part in an interview from space with television networks. The interview will air live on NASA TV.

• 2001 Aug 15 - STS-105 Mission Status Report #10 

  Discovery's astronauts were awakened shortly after 4 a.m. Central time to the sounds of "Big Boy Toys", a country and western tune by Aaron Tippin, selected for Pilot Rick Sturckow by his wife.

  The wakeup call began a day that will focus on preparations for the first of two space walks by Mission Specialists Dan Barry and Pat Forrester on Thursday, while members of the International Space Station Expedition Two crew will continue the handover of station operations to their Expedition Three replacements.

  The crews also have time scheduled for logistical activities, including the transfer of more equipment and supplies from Discovery to the station and the transfer of discarded station equipment to Leonardo, the Multi-Purpose Logistics Module, which was installed on the station on Monday. The 7,000 pounds of material carried into space aboard Leonardo, including two scientific experiment racks for the U.S. Laboratory Destiny, has been unloaded.

  Sturckow will assist Barry and Forrester as they checkout their spacesuits and space walking tools for their planned 61/2-hour excursion outside Discovery tomorrow. During the space walk, Barry and Forrester will install the Early Ammonia Servicer on the station's P6 truss structure. It contains spare ammonia that could be used in the station's cooling system should the need arise. They will also attach an experiment to the station to expose samples of engineering materials to the space environment. The samples will be returned to Earth for analysis in about a year.

  A second space walk will be conducted by Barry and Forrester Saturday to hook up heater cables for a truss structure which will be delivered to the station next year.

  Hatches between Discovery and the station will swing shut around 4:30 Central time this afternoon in advance of tomorrow's space walk

  Earlier today, Russian flight controllers successfully completed the reloading of upgraded software into the computers of the Zvezda Service Module in preparation for next month's arrival of a new module to the station -- the Russian Docking Compartment -- which will serve as a new docking port for visiting Russian vehicles.

  Additionally, everything remains on schedule for the launch next week of a new unmanned Progress resupply vehicle to the station, carrying more supplies and hardware for the new Expedition Three crew. The Progress will be launched from the Baikonur Cosmodrome in Kazakhstan on Tuesday and will link up to the station on Aug. 23.

• 2001 Aug 15 - STS-105 Mission Status Report #11 

  The hatches swung closed between Discovery and the International Space Station at 4:52 this afternoon Central time so that the shuttle's cabin pressure could be lowered in preparation for a space walk Thursday by Dan Barry and Pat Forrester.

  In preparation for that Extravehicular Activity (EVA), the crew spent part of the day checking out the suits that will be worn for the planned six and a half hour excursion to install an ammonia servicing unit on the outside of the station. It contains spare ammonia that could be used in the station's cooling system if needed. They also will attach an experiment to the station to expose samples of engineering materials to the space environment. The samples will be returned to Earth for analysis in about a year.

  A second space walk currently is planned for Saturday to hook up heater cables for the first of several girder-like truss structures, that will be delivered to the station next year.

  Meanwhile, members of the station's Expedition Two crew continued the handover of station operations to their Expedition Three replacements. Throughout the handover, the stowage of equipment and supplies inside the Leonardo Multi-Purpose Logistics Module continued. Some 5,200 pounds of supplies was confirmed on board the station and will be unpacked and stowed by the Expedition Three crew after Discovery departs early next week.

  Early in the day, Russian flight controllers completed the reloading of upgraded software into the computers of the Zvezda module in preparation for next month's arrival of a new module to the station, the Russian Docking Compartment, which will serve as a new docking port for visiting Russian vehicles.

  The Russian flight control team continues to track preparations of a Soyuz spacecraft set to deliver the next Progress supply vehicle to the station. Launch from the Baikonur Cosmodrome in Kazakhstan remains targeted for Tuesday with docking Aug. 23.

  Early Thursday morning, the Expedition Three crew of Frank Culbertson, Vladimir Dezhurov and Mikhail Tyurin plan to televise a commemorative message marking the one-thousandth day in space for the International Space Station. It was Nov. 20, 1998 when the first element - Zarya - was launched atop a Proton rocket initiating the construction of the orbiting outpost.

  Discovery and the station are orbiting the Earth every 90 minutes at an average altitude of 246 statute miles with no systems issues being worked by the flight control team.

• 2001 Aug 16 - STS-105 Mission Status Report #13 

  Astronauts Dan Barry and Pat Forrester completed the first of two planned space walks during Discovery's voyage to the International Space Station. The excursion lasted 6 hours, 16 minutes and involved installing the Early Ammonia Servicer and the first external experiment on the station's hull. The servicer contains spare ammonia that can be used in the space station's cooling systems if needed. The Materials ISS Experiment (pronounced 'missy' by its acronym) will expose 750 material samples to the space environment for about 18 months before being returned home late next year. During the space walk, Discovery's Commander Scott Horowitz operated the shuttle robot arm, and Pilot Rick Sturckow choreographed the space walk from the orbiter's flight deck. This was the 25th space walk devoted to the construction of the space station and the 12th this year. Barry and Forrester will perform the mission's second space walk on Saturday to hook up heater cables for another truss structure to be delivered to the station next year. Mission managers Friday will evaluate the consumables onboard Discovery and assess the progress made by the crews in transferring items into the Leonardo logistics module from the station before making a determination as to whether the docked phase of the flight should be extended by one day.

  Earlier today, the computers inside the Zvezda module once again assumed control of the station's attitude - or position in space -- after Russian flight controllers completed the loading of upgraded software commands to those computers.

  With crewmembers aboard Discovery ready for their return to Earth, the new Expedition Three crew aboard the International Space Station prepared for the arrival of a Progress resupply vehicle early tomorrow morning.

  Discovery is about 1,300 statute miles ahead of the space station and widening the gap by about 50 miles per 90-minute orbit. The seven-member crew - Commander Scott Horowitz, Pilot Rick Sturckow, Mission Specialists Dan Barry and Pat Forrester, along with the returning Expedition Two crew members, Commander Yury Usachev and Flight Engineers Susan Helms and Jim Voss - were awakened at 3:10 a.m. CDT to begin a day with two landing opportunities at Florida's Kennedy Space Center. Weather conditions in Florida hold promise for today's landing, but the entry team of flight controllers will be watching for a chance of rain near the landing site.

  The first opportunity would see a deorbit burn at 10:37 a.m., resulting in an 11:46 a.m. CDT (12:46 p.m. EDT) landing. Discovery would descend across southern Mexico, cross the Bay of Campeche, skirt the northwestern tip of the Yucatan Peninsula, and cross the Gulf of Mexico before making landfall on Florida's western coast. For the second opportunity, the deorbit burn would occur at 12:17 p.m. The shuttle would cross northern Mexico, descend over the Rio Grande near Laredo, and fly along the Gulf Coast before crossing the Florida peninsula for a 1:23 p.m. landing.

  Aboard the International Space Station, the Expedition Three crew - Commander Frank Culbertson and Cosmonauts Vladimir Dezhurov and Mikhail Tyurin - were awakened a little after midnight for the undocking of the Progress 4 vehicle. That spacecraft was moved to make way for the Progress 5 cargo vehicle which launched at 4:24 a.m. Tuesday from the Baikonur Cosmodrome in Kazakhstan and is scheduled to dock at the rear of the space station's Zvezda Service Module about 5 a.m. tomorrow.

  Progress 4 docked to the space station last May 22 with a cargo of equipment, food, fuel and spare computer parts. After unloading, it was refilled with trash. Just before 1 a.m. flight controllers at Moscow's Mission Control Center sent the command for it to undock. About three minutes later, springs pushed it away from the station, and three minutes after that, Progress jet thrusters were fired to increase the separation rate. At about 4 a.m. a deorbit burn command initiated its descent to fiery destruction in the Earth's atmosphere.

  Discovery is circling the Earth every 90 minutes at an average altitude of about 240 statute miles. Systems aboard the shuttle and the space station are functioning well.
