    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-037

    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.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-038

    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 STATUS REPORT: SS05-039

    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.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-040

    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.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-041

    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 MODIFIES BOEING INTERNATIONAL SPACE STATION CONTRACT

    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.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-043

    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.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-045

    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.

    Ein geplantes Manöver die ISS wieder in eine höhere Umlaufbahn zu bringen ist heute unerwartet wegen einer Fehlfunktion in der russischen Steuerung des Progress-Moduls fehlgeschlagen, statt 11 Minuten Schub in einer ersten Schubphase feuerten die Triebwerke nur 2 Minuten und ein Höhengewinn von etwas über einen Km. Die technische Ursache der Fehlfunktion wird derzeit noch geklärt, ein besonders großes Problem ist dies nicht.

    Es wird wahrscheinlich noch im Laufe des Tages über einen zweiten Anlauf entschieden, die ISS wieder in einen höheren Orbit zu bringen. Die russische Weltraumagentur ist zuversichtlich dies durchführen zu können, da die Notabschaltung beim letzten Versuch darauf zurückging, das ein Überwachungssystem einen nicht-synchronen Brennverlauf von zwei Triebwerken festgestellt hatte und daher abschaltete.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-049

    The 12th international space station crew turned its attention this week to experiment work aboard their microgravity home and laboratory. They captured spectacular images of Hurricane Wilma (available on the Web and NASA TV) and prepared for a spacewalk.

    Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev began reviewing procedures for the first station-based spacewalk using U.S. suits since 2003.

    During the November 7, five and one half hour spacewalk, they will install a new video camera on the far end of the station's P1 (port) truss. They also will remove a probe that measured the electrical potential around the station from the top of the P6 truss.

    Yesterday, the station's atmosphere was repressurized with oxygen from storage tanks on the docked Progress supply ship. Russian specialists are preparing a troubleshooting plan for the Elektron, the primary oxygen generation system on the station. It stopped working late last week.

    Russian technical specialists are examining what caused the abort of a planned altitude reboost Tuesday using Progress fuel and thrusters.
    Mission managers believe Russian navigation computers properly shut down the thrusters when they lost information about how they were performing. A planned test firing of the thrusters Wednesday will gather more data for Russian engineers.

    McArthur checked out a system to analyze exhaled gases inside the station. The Pulmonary Function System took more than eight years of design, development and testing on Earth by U.S. and European Space Agency scientists. It was delivered to the station by the shuttle Discovery in July. McArthur and Tokarev conducted the first of three sessions with the Renal Stone experiment. They collected urine samples for return to Earth and logged all food and drink consumed during a 24-hour period.

    This ongoing experiment investigates whether potassium citrate can be used to reduce the risk of kidney stone formation for space travelers. The citrate minimizes kidney stone development on Earth.

    Since urine calcium levels are typically much higher in space, astronauts are susceptible to an increased risk of developing kidney stones. An understanding of the crew's diet during the urine collection timeframes will help researchers. They will determine if the excess calcium in the urine is due to diet or a response to the microgravity environment. The payload operations team at NASA's Marshall Space Flight Center, Huntsville, Ala., coordinates U.S.
    science activities on the station.

    During their six-month mission, McArthur and Tokarev will conduct at least two spacewalks and oversee the arrival of the next Progress supply vehicle in December. They also will relocate their Soyuz spacecraft to free the Russian Pirs docking port for a later spacewalk. Pirs doubles as an airlock and docking module.

    Obwohl der US Kongress und Senat Russland durch Handels-Sanktionen davon abbringen will den Iran weiterhin mit Wissen und Ausrüstung für sein ziviles Nuklear-Programm zu versorgen, hat man nun einheitlich beschlossen, dass die NASA auch weiterhin Soyuz-Flüge in Russland einkaufen darf, um die Versorgung der ISS sicher zu stellen.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-050

    Commander Bill McArthur and Flight Engineer Valery Tokarev checked the clothes, tools and plans they will use during a five and one half-hour spacewalk set for Nov. 7.

    McArthur and Tokarev will mark five years of continuous human presence on the international space station Nov. 2. They are the 12th station crew. The first station crew, Commander Bill Shepherd, Flight Engineers Sergei Krikalev and Soyuz Commander Yuri Gidzenko, arrived at the complex on Nov. 2, 2000.

    Originally the size of an efficiency apartment, the station has grown to a volume larger than the average three-bedroom house, equipped with the most sophisticated laboratory ever to fly in space. The station is functioning as a test bed for technologies, procedures and human endurance that will allow future, longer space journeys.
    McArthur and Tokarev sent an anniversary greeting this week to the prior station crews and to the thousands who support the station in
    16 nations.

    On Tuesday, the crew performed a checkout of the spacesuits they will wear for their spacewalk. The spacewalk will be the first from the station to use U.S. spacesuits and originate from the Quest Airlock since April 2003.

    The crew will install a TV camera on the station's port side truss.
    The camera will be an important aid during future assembly work They also plan to remove an experiment from the top of the P6 truss, the station's highest point. The experiment measured the electrical environment around the exterior of the station.

    On Wednesday, the crew tested procedures to put on and take off spacesuits, reviewed plans and conferred with spacewalk specialists on the ground. Thursday they suited up and rehearsed the activities inside the station they will perform outside. The spacewalk will begin about 9:30 a.m. EDT with coverage on NASA TV beginning at 8:30 a.m. EDT, Nov. 7.

    All station systems are operating well. The Elektron oxygen-generating system, one of several methods of replenishing oxygen in the station cabin atmosphere, is functioning. It was restored to operation Saturday, when Tokarev performed a maintenance procedure to purge air bubbles from its systems.

    Russian flight controllers completed a test firing of thrusters on the Progress cargo craft on Wednesday. The thrusters shut off early last week during a planned reboost of the complex. The thrusters were fired using a different manifold, as Russian controllers continued to evaluate a loss of data from the system observed during the aborted reboost. During the test firing, the engines operated normally. They are planned for use during the next reboost of the station on Nov. 10.

    Die ISS ist jetzt seit 5 Jahren bemannt. Man hatte zwar gehofft, jetzt schon deutlich weiter zu sein, aber angesichts der sehr turbulenten Zeiten im Raumfahrt-Sektor ist man schon froh das zu haben, was man hat.

    Man bereitet sich auf einen weiteren Außeneinsatz vor und hat wieder einiges an schadhaften Systemen repariert/ausgetauscht.


    The Expedition 12 crew prepared for the mission's first spacewalk and kept the station ship-shape this week.

    Station Commander Bill McArthur and Flight Engineer Valery Tokarev reviewed procedures and prepared tools for the spacewalk. It starts at 9:30 a.m. EST, Monday. Coverage on NASA TV begins at 8:30 a.m.
    EST.

    The spacewalk is the first using U.S. spacesuits since 2003. During the 5.5 hour spacewalk, the crew will install a TV camera on the station's port truss. The camera will be an important aid during future assembly work. The crew also will remove an old experiment from the top of the P6 truss, the station's highest point. The experiment measured the electrical environment around the station.

    The station passed the milestone of five years of human presence aboard the complex.

    The first station crew, Commander Bill Shepherd and cosmonauts Sergei Krikalev and Yuri Gidzenko, arrived at the complex on Nov. 2, 2000.

    The crew also focused on hardware maintenance. Monday they disassembled and measured air flow in the Trace Contaminant Control System. It keeps a clean, healthy atmosphere by filtering out contaminants in the air. Engineers noticed a reduction in the air flow, and after the crew examined its components, determined that replacement hardware may need to be delivered on a future supply ship. After reassembling the device, the system is running at a slightly reduced capacity, complemented by a fully operational and complementary system in the Russian segment.

    The crew also replaced a faulty pump in a thermal control loop and smoke detectors in the Zvezda Service Module and cleaned ventilation filters in the Zarya module.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-053

    With their first spacewalk behind them, the crew of the International Space Station pressed ahead this week to prepare for several upcoming milestones.

    Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev get a special musical wakeup call this weekend as Paul McCartney connects with them live from a concert in Anaheim, Calif.
    The call will take place at 12:55 a.m. EST Sunday and will be broadcast live on NASA Television and www.nasa.gov.

    McArthur and Tokarev spent the week servicing the spacesuits used Monday for a 5 hour, 22 minute excursion outside the station. During the spacewalk, they installed a television camera, jettisoned an inactive science experiment and removed and replaced other equipment on the truss system of the complex.

    The crew's second spacewalk is planned for Dec. 7. McArthur and Tokarev will don Russian Orlan spacesuits and exit the Pirs Docking Compartment airlock for that excursion. During the spacewalk, they will move a cargo crane adapter, collect science experiments from the hull of the Zvezda Service Module and manually launch an expired Russian spacesuit equipped with amateur radio equipment. Called SuitSat, the experiment is designed to see if ham radio contacts can be made with a free-flying transmitter.

    To prepare for the spacewalk, McArthur and Tokarev will relocate their Soyuz spacecraft from the Pirs docking port to the nadir docking port of the Zarya module on Nov. 18, briefly leaving the station unoccupied.

    Earlier today, four thruster engines on the Progress cargo spacecraft were fired for more than 33 minutes in two separate reboost maneuvers to raise the altitude of the outpost. The station is now in a near circular orbit of 219 miles to accommodate the launch and docking of the next resupply ship in December. The reboost was the longest ever completed using Progress engines.

    On Wednesday, Tokarev replaced a control panel for the station's toilet in Zvezda that had malfunctioned earlier in the week. The temporary loss of the use of the device's liquid disposal component had no impact on station operations. Following the troubleshooting, the toilet is now operating normally.

    INTERNATIONAL SPACE STATION STATUS REPORT: SS05-054

    Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev took a short ride around the International Space Station today, flying their Soyuz spacecraft from one docking port to another.

    The crew left the station unoccupied for approximately 30 minutes, as they relocated the Soyuz. Tokarev undocked the spacecraft at 3:46 a.m. EST, while the station orbited 225 miles above the Atlantic, and docked to the nearby Zarya module at 4:05 a.m. EST.

    The Soyuz move freed the Pirs Docking Compartment airlock for an upcoming spacewalk. The Soyuz is the crew's ride home at the end of their six-month stay on the station. It also serves as a lifeboat.

    The crew must finish unpacking the Progress cargo spacecraft docked to the complex, prepare it for undocking and get ready for the Dec. 23 arrival of the next supply ship. McArthur spent several hours photographing samples of colloids that had been undisturbed in the station's microgravity environment for more than a year. The work is part of an experiment called the Binary Colloidal Alloy Test. The behavior of these supercritical fluids is important because they combine the properties of liquids and gases. A better understanding of their reaction in the weightless environment of space could help in the development of new drugs, cleaner power and interplanetary transportation.
