    Expedition 11 Commander Sergei Krikalev and Flight Engineer John Phillips left the Space Station today and moved their Soyuz spacecraft from one docking port to another.

    The Soyuz moved away from the Pirs Docking Compartment at 6:38 a.m. EDT, while the Station flew above the Atlantic Ocean east of the southern tip of South America. Redocking to the Zarya Module's Earth-facing port occurred at 7:08 a.m. EDT, over Central Asia.

    Krikalev guided the Soyuz as it backed away about 82 feet from Pirs. Krikalev commanded the Soyuz to fly laterally along the Station about 45 feet and rotated it to align with the Zarya's docking port. Hooks and latches in the two docking mechanisms established a firm connection between the Soyuz and Zarya. The crew re-entered the Station at 8:20 a.m. EDT, to reconfigure systems for normal operations.

    The move cleared the Pirs airlock for an August spacewalk. During the walk, Krikalev and Phillips will remove materials exposure experiments, install a television camera for the European Space Agency's cargo-carrying Automated Transfer Vehicle and relocate a cargo boom adapter.

    The Soyuz will be used to bring the crew home at the end of its six-month mission and could also serve as a lifeboat in the event of a Station evacuation.

    International Space Station Status Report #05-38

    Expedition 11 Commander Sergei Krikalev and Flight Engineer John Phillips got ready this week for two upcoming Space Shuttle launches and a Space Station spacewalk, and supported two different continuing science investigations.

    With the 100th day of their six-month mission coming up on July 23, the International Space Station crew members reported in a Friday interview that they are eagerly anticipating Discovery’s arrival next week with tons of supplies, a new experiment rack and a replacement Control Moment Gyroscope (CMG) for the Station’s navigation system. They have been packing equipment that will return home on Discovery to free up much-needed space inside the outpost, and this week they began packing for the STS-121 mission of Atlantis that will follow.

    Earlier in the week, Krikalev and Phillips made a short foray in their Soyuz return craft, moving it from the Pirs docking port, which doubles as an airlock for Russian-suit spacewalks, to a Zarya docking port to configure the Station for an August excursion. The pair undocked from Pirs at 5:38 a.m. CDT Tuesday, and smoothly redocked at the nearby Zarya control module’s Earth-facing port at 6:08 a.m. CDT.

    The post-Discovery spacewalk by Krikalev and Phillips will involve retrieval of materials exposure experiments, installation of a television camera for the European Space Agency’s cargo-carrying Automated Transfer Vehicle and relocation of a cargo boom adapter.

    Phillips supported research this week by setting up a digital still photo camera in the Destiny Laboratory’s window for the continuing EarthKAM student experiment. After the crew mounts the window camera, middle school students research requests for specific geographic targets, and with the help of university students, uplink commands to a laptop computer connected to the camera. The camera takes pictures at specified times, and the images are downlinked to the ground to be posted on the Internet for the public and participating classrooms around the world. The current EarthKAM run has taken photo requests from 43 schools.

    Krikalev spent time setting up and activating a plasma crystal experiment so that it could conduct automated experiments using radio frequency waves to affect crystal formation in microgravity. The experiment is a joint project of the Russian and German space agencies.

    After saying goodbye to the Space Shuttle Discovery's crew on Saturday, International Space Station (ISS) Commander Sergei Krikalev and NASA Science Officer John Phillips spent much of the week preparing for a spacewalk scheduled for next week.

    The six-hour spacewalk begins at 2:55 p.m. EDT, Thursday. Live coverage on NASA TV starts at 1:30 p.m. EDT.

    On the spacewalk, the crew will change out a Russian biological experiment, retrieve some radiation sensors, remove a Japanese materials science experiment, photograph a Russian materials experiment, install a TV camera and relocate a grapple fixture.

    At 1:44 a.m. EDT, Tuesday, Krikalev's time spent in space will surpass any other human. Cosmonaut Sergei Avdeyev set the previous record with 748 days in orbit. Krikalev is a veteran of two long-duration flights to the Soviet Union's Space Station Mir; two flights on the Shuttle; and two flights to the ISS. Krikalev was aboard Mir when the Soviet Union disintegrated; was the first Russian to fly on the Shuttle in 1994; was a member of the Shuttle crew that began assembly of the ISS in 1998; and a member of the first crew to live on board the Station in 2000.

    Krikalev and Phillips had an off-duty day on Sunday. On Monday they unpacked and prepared spacewalk tools and the Pirs docking compartment. They will use the Pirs for the spacewalk. During the week, they checked the Russian Orlan spacesuits they will wear and talked with spacewalk experts in the Russian Mission Control Center and in Houston.

    On Thursday, the Russian Vozdukh carbon dioxide removal system shut down. The system is one of multiple systems used to scrub the Station cabin air. Flight controllers in Houston activated a U.S. Carbon Dioxide Removal Assembly to perform that function while the Vozdukh is not operating. Russian specialists are analyzing the problem.

    International Space Station (ISS) Expedition 11 crew members completed a spacewalk just days after the Station commander became the most experienced space traveler.

    Thursday's 298 minute spacewalk by Commander Sergei Krikalev and Flight Engineer John Phillips was the 62nd to support Station assembly and maintenance. It was the 34th from the Station and 16th from the Pirs docking compartment.

    The crew's first job was retrieval of one of three canisters from the Biorisk experiment, a study of the impact of spaceflight on bioorganisms. It was installed on the Pirs module by Expedition 10 in January; other canisters will be retrieved on later spacewalks.

    The crew moved to the large diameter section of the Zvezda module and prepared two experiment payloads for removal. The Micro-Particles Capturer uses aerogels and foam to collect natural and human-made orbital debris outside the Station. The Space Environment Exposure Device has samples of possible spacecraft materials like paint, insulation and lubricants, exposed to the low Earth orbit environment. Matroshka is a biomedical experiment collecting data on radiation absorption by crew members on long-duration missions, especially when spacewalking.

    The crew moved aft of Zvezda to install a backup TV camera to assist docking the European Space Agency's Automated Transfer Vehicle, a new cargo craft set to make its first flight next year. The crew documented the condition of the Kromka experiment, which measures residue from firing nearby jet thrusters. They also exchanged sample containers in the Russian materials' exposure experiment called SKK.

    By the time the crew transported the experiments and their tools inside Pirs, they were about 45 minutes behind schedule. The estimated two hours necessary to complete the last task, relocation of a Strela cargo crane adapter from Zarya to Pressurized Mating Adapter 3 on the Unity node, caused Russian mission managers to postpone it until a later spacewalk.

    Yesterday's spacewalk was Phillips' first and Krikalev's eighth. He collected 36 hours and 10 minutes spacewalking experience on seven excursions during two missions on the Russian MIR space station.

    On August 16, at 1:44 a.m. EDT, Krikalev's total time in space surpassed Cosmonaut Sergei Avdeyev's record of 747 days, 14 hours and 14 minutes. Krikalev flew two missions to Mir; two Shuttle missions; and two ISS missions.

    The Station's Russian Vozdukh carbon dioxide removal system has been shut down since August 11. Russian specialists are working on a recovery plan. The Carbon Dioxide Removal Assembly (CDRA) in the U.S. portion of the ISS, which has been scrubbing the air since Vozdukh's shut down, failed Thursday morning. It failed due to a stuck check valve, the latest instance of a known and understood problem.

    The CDRA is being managed back to operation by flight controllers in Houston. The crew was informed carbon dioxide levels on the Station are well below dangerous levels. Plans call for Krikalev to perform troubleshooting on Vozdukh today.

    The crew of the International Space Station (ISS) unloaded cargo delivered last month on the Space Shuttle Discovery. They also prepared for the arrival of more supplies and repaired a key component of the environmental control system.

    In the fifth month of their six-month mission, Expedition 11 Commander Sergei Krikalev and NASA Flight Engineer and Science Officer John Phillips finished unpacking cargo bags transferred to the Station's Zarya module from Discovery three weeks ago. All the unpacked items were entered into the Station's computerized inventory system. The crew will also unload bags stowed in the Unity and Zvezda modules.

    Today, the crew began loading the Progress resupply craft docked at the aft end of Zvezda with trash and unneeded gear. The spacecraft will undock from the complex at 6:23 a.m. EDT, Sept. 7. It will fire its engines; enter the Earth's atmosphere and burn up over the Pacific Ocean.

    At 9:08 a.m. EDT, Sept. 8, a new Progress, the 19th to visit the Station, will launch from the Baikonur Cosmodrome in Kazakhstan. Filled with more than 2.5 tons of food, fuel, oxygen, water and spare parts, the spacecraft will automatically dock to the ISS at 10:50 a.m. EDT, Sept. 10. The docking will be broadcast live on NASA TV.

    A new liquids unit for the Russian Elektron oxygen-generation system, which failed several months ago, will be on board the Progress. The liquids unit circulates water through the Elektron, separating it through electrolysis into hydrogen and oxygen. The hydrogen is vented over board and the oxygen is circulated into the Station's atmosphere for breathing.

    While Elektron has been inactive, oxygen from the Progress tanks was used to repressurize cabin atmosphere. Multiple sources of oxygen, with ample supplies, are available for use by the crew.

    On Tuesday, Krikalev repaired the Vozdukh carbon dioxide removal system by replacing a faulty valve. Vozdukh shut down late last week, prompting the temporary use of another air-scrubbing system, the U.S. Carbon Dioxide Removal Assembly in the Destiny Laboratory.

    Also on Tuesday, Krikalev and Phillips discussed life and work aboard the Station with students gathered at the Cincinnati Museum Center in Ohio. The educational event was broadcast to schools in the Ohio Valley.

    On Wednesday, Phillips replaced a failed laptop computer used to house inventory and information about the Station's medical supplies. The computer experienced problems three weeks ago during Discovery's visit.

    The Expedition 11 crew also spent 90 minutes Wednesday practicing emergency procedures during an exercise that simulated the rapid depressurization of the Station's cabin. Rehearsals of this nature are conducted periodically to maintain proficiency for the crew and flight controllers.

    In addition to exercise and routine maintenance, the crew stowed spacewalking tools used last week during their excursion outside the Pirs Docking Compartment to retrieve experiments and hardware. The spacewalk was the only one planned for Expedition 11.

    The crew of the International Space Station (ISS) completed 20 weeks in space, focused on an upcoming cargo ship exchange and computer software transition.

    Expedition 11 Commander Sergei Krikalev and NASA Flight Engineer and Science Officer John Phillips packed the docked ISS Progress 18 supply ship with items no longer needed on the Station. The unpiloted cargo craft undocks from the Zvezda module at 6:23 p.m. EDT, Wednesday, Sept. 7. The Progress will burn up in Earth's atmosphere above the Pacific Ocean.

    A new supply ship, ISS Progress 19, launches from the Baikonur Cosmodrome at 9:08 a.m. EDT, Thursday, Sept. 8 and docks at 10:50 a.m. EDT, Sept. 10. It will deliver approximately 5,000 pounds of food, water, fuel, clothing and other supplies. It will also deliver a new liquids unit for the Elektron, a primary oxygen-generating system, and spare parts for the Vozdukh carbon dioxide removal system.

    Krikalev and Phillips prepared new laptop computers for a software upgrade. They also conducted a routine rehearsal of emergency procedures, simulating an emergency departure from the Station in the Soyuz. The crew members also checked out new blood pressure and electrocardiograph equipment delivered by the Space Shuttle last month.

    On Monday, Phillips conducted an interview with Oregon Public Broadcasting for a series celebrating the bicentennial of the exploration of the American West. Phillips talked about the similarities and differences of space exploration and the journey of Lewis and Clark.

    A new shipment of supplies is on its way to the International Space Station (ISS). The 19th Progress spacecraft to visit the ISS lifted off today from the Baikonur Cosmodrome, Kazakhstan, at 9:08 a.m. EDT. Less than 10 minutes later, the cargo ship reached orbit, and solar arrays and navigational antennas were deployed successfully for the two-day trip.

    Expedition 11 Commander Sergei Krikalev and Flight Engineer and NASA Flight Engineer and Science Officer John Phillips were flying 220 miles over the Pacific Ocean when the Progress launched.

    Carrying more than 5,000 pounds of food, water, fuel, clothing, spare parts and other supplies, the Progress is scheduled to automatically dock to the station's Zvezda Service Module on Saturday at 10:50 a.m. EDT. The craft is delivering a new water circulation device, known as a liquids unit, for the station's Elektron oxygen-generating system. The unit will be installed next week to try to bring Elektron back into service.

    Nearing the end of their fifth month in space, Krikalev and Phillips completed packing the old Progress with unnecessary items. The unpiloted cargo craft undocked from the Zvezda module's aft port at 6:26 a.m. EDT, Wednesday. It was deorbited and burned up in the Earth's atmosphere over the Pacific Ocean.

    Also this week, Krikalev and Phillips replaced parts inside the treadmill exercise machine in Zvezda. New components were delivered aboard the Space Shuttle Discovery in July for a routine upgrade of the system. After two days of maintenance, Phillips activated the treadmill. He reported it is operating normally and available for daily use.

    NASA signed a $68.35 million modification to the International Space Station contract with The Boeing Company. The modification provides a system to supply Station electrical power to docked Space Shuttles, enabling the Orbiter to stay longer at the complex.

    The Station-Shuttle Power Transfer System (SSPTS) allows the Orbiter to use electricity generated by the Station's solar arrays. The additional Station power supplements Shuttle fuel cells, saving onboard supplies of hydrogen and oxygen.

    The Station power will allow Shuttles to dock up to 12 days instead of up to eight days. The longer stay allows additional time for spacewalks, Station maintenance performed by Shuttle crews, Orbiter thermal protection system inspection, contingency repairs, logistics transfers and science operations.

    The change includes the design, development, manufacture, qualification, testing, delivery and instructions for installation of the SSPTS hardware, software and support equipment into the Station and Shuttle. The SSPTS will be installed in the first Shuttle in spring 2006. The first flight is targeted for Shuttle mission STS-119, the mission to deliver the final component of the truss and solar array structure that provides the Station's power.

    The contract modification culminates with delivery of all SSPTS components, integration and testing of the hardware and software in spring 2007. The work will be performed at Boeing facilities in Houston; Kennedy Space Center, Fla.; Canoga Park, Calif.; Huntington Beach, Calif.; and Seattle.

    An unpiloted Russian Progress cargo ship docked to the aft port of the International Space Station (ISS) Zvezda module today at 10:42 a.m. EDT, as the Station flew 220 miles above Central Asia near northern Kazakhstan. The 19th Progress spacecraft to visit the ISS is carrying more than 5,000 pounds of supplies for the crew.

    Expedition 11 Commander Sergei Krikalev and Flight Engineer John Phillips will check for leaks before opening the hatch to the Progress later today. They'll begin unloading the cargo tomorrow.

    The supplies include food, fuel, oxygen and air, clothing, experiment hardware, Russian spacesuit components and spare parts for the Vozdukh carbon dioxide removal system. A new water circulation liquids unit is onboard the supply ship. This unit is for the station's Elektron oxygen-generating system which is inoperable. The unit will be installed next week to try to bring Elektron back into service.

    The remainder of the Progress payload includes 1,763 pounds of propellant for the Russian thrusters; 242 pounds of oxygen and air in tanks as a backup supply for the oxygen generated by Elektron; and 463 pounds of water to augment the supplies left by the Space Shuttle Discovery during the STS-114 mission.

    Some of the clothing and personal effects delivered to the station include items for the next resident crew, Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev. They are scheduled to launch from the Baikonur Cosmodrome in Kazakhstan Oct. 1 in the Soyuz TMA-7 capsule.

    NASA and Russian flight controllers outside Moscow are in control of the International Space Station, after mission control in Houston was evacuated ahead of Hurricane Rita. Aboard the station, Expedition 11 Commander Sergei Krikalev and Flight Engineer John Phillips have a key piece of life support equipment up and running, just in time for the next space station crew.

    The crew activated the repaired Elektron oxygen generator this week. The Elektron, which extracts oxygen from water, was put into service early Monday. Krikalev and Phillips repaired the Elektron with a new liquids unit that was brought up on a recent Progress spacecraft. Krikalev and Phillips also performed maintenance on the on-board treadmill, a key piece of exercise equipment to help keep astronauts' bones and muscles strong during long stays in zero-gravity. They worked on an experiment designed to test the effects of certain compounds on kidney stones, and they collected water samples to be analyzed once they return to Earth.

    The Expedition 11 crew is nearing the end of its six-month stay on the station, and crew members spent part of the week packing up their return spacecraft, the same Russian Soyuz that brought them to the station in April. They also tested out their shock-absorbing seats for their landing, scheduled for October 10, U.S. time.

    With Hurricane Rita strengthening in the Gulf of Mexico and targeting the Texas shoreline, the space station program activated a well-rehearsed plan to allow flight controllers based at NASA's Johnson Space Center, Houston, to evacuate. They transitioned full control of the station to Moscow, where Russian mission control and a permanently staffed cadre of NASA flight controllers, known as the Houston Support Group, are keeping the station operating smoothly. Other agency resources were tapped to ensure the station's safe flight. For example, at Goddard Space Flight Center, Greenbelt, Md., two flight controllers arrived from Houston to maintain communications with the station through Goddard's Network Integrated Communications flight control room.

    The next space station crew, Expedition 12's Bill McArthur and Valery Tokarev, are beginning their journey toward launch. They traveled this week from the Russian training facility at Star City to the Baikonur Cosmodrome in Kazakhstan, where they'll launch to the station Sept. 30 aboard a Soyuz. During their station stay, McArthur and Tokarev will mark five years of continuous human presence in orbit and pursue the station's mission of learning how to live and work for long periods in space.

    A Russian Soyuz spacecraft carrying Expedition 12 Commander William McArthur, Flight Engineer Valery Tokarev and American businessman Gregory Olsen arrived at the international space station this morning after a two-day journey.

    McArthur and Tokarev are beginning a six-month mission aboard the orbiting laboratory. Olsen will spend eight days there conducting scientific and photography experiments under a commercial agreement with the Russian Federal Space Agency.

    With Tokarev at the controls, the Soyuz automatically linked up to the Pirs Docking Compartment today at 1:27 a.m. EDT. After systems checks, hatches between the Soyuz and station opened at 4:36 a.m. EDT. Expedition 11 Commander Sergei Krikalev and Flight Engineer John Phillips greeted their colleagues with handshakes, hugs and the traditional offering of bread and salt.

    Krikalev and Phillips have spent 169 days on the station since they arrived in April.
    They, along with Olsen, return to Earth at 9:08 p.m. EDT, Oct. 10 in the Soyuz spacecraft docked to the station's Zarya module.

    Shortly after entering the space station, the Expedition 12 crew and Olsen had a safety briefing on emergency escape procedures. They will transfer Olsen's custom-made seat liner to the Soyuz he will use to return home. The crews will also move cargo from the newly-arrived Soyuz to the station.

    This week McArthur and Tokarev will familiarize themselves with station systems and stowed equipment, conduct robotics training with the Canadarm2 robot arm and receive detailed briefings about scientific payloads.
