International Space Station Status Report: SS05-047
Following the docking of the Soyuz spacecraft early Monday morning, the International Space Station is now home to a new crew. Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev, joined by spaceflight participant Gregory Olsen, spent the week on board with the Expedition 11 crew performing handover and transfer activities.

McArthur, Tokarev and Olsen arrived at the space station at 1:27 a.m. EDT Monday, Oct. 3, and entered the orbital laboratory at 4:36 a.m. EDT. For McArthur and Tokarev, the station will serve as home for the next six months.

The crews began joint activities with safety briefings and a review of emergency escape procedures. The remainder of the first day together for the two crews included initial handover briefings, deactivation of the Soyuz spacecraft, and drying and stowage of the Russian Sokol spacesuits worn during launch.

Handover activities continued throughout the week. On Tuesday, Expedition 11 Flight Engineer John Phillips and McArthur reviewed robotic arm software that provides graphical depictions of the station's exterior to aid in arm operations. The following day, the two performed several maneuvers using the Canadarm2 to acquaint the new crew with how the station's robotic arm behaves in the space environment.

The crews also conducted experiments. The studies included the Intercellular Interactions experiment, a Russian study of the effect of microgravity on cell surfaces and intercellular interactions, and an experiment that studies the process of genetic material transmission in bacteria. Other experiment work included a study of the growth and development of higher plants in space, a study of changes in the human cardiovascular system in orbit and an investigation designed to help researchers understand the effect of radiation exposure on human organs.

The crews also fielded questions from media during a news conference and several interviews this week and received a special phone call Thursday from Russian Prime Minister Mikhail Fradkov. Fradkov congratulated the crews on their work and discussed his country's commitment to the International Space Station program.

Also this week, the crews installed radiation monitors and temperature sensor switching units, inspected U.S. emergency power supplies and smoke detectors, and replaced a laptop computer.

The crews will have some brief off-duty time this weekend, but will focus on completing handover and preparations for Expedition 11's return home. Expedition 11 Commander Sergei Krikalev and Phillips are scheduled to undock from the station at 5:45 p.m. EDT and land at 9:09 p.m. EDT on Monday in Kazakhstan.

NASA Television coverage of the crew's farewells will begin at 2 p.m. EDT Monday as they say their goodbyes and close the hatches between the station and the Soyuz spacecraft. NASA TV coverage of the undocking will begin at 5 p.m. EDT. Coverage of the deorbit burn will begin again at 7:45 p.m. and continue through landing. The deorbit burn is scheduled for 8:19 p.m. EDT.

For continental North America, NASA TV is carried on an MPEG-2 digital signal accessed via satellite AMC-6, at 72 degrees west longitude, transponder 17C, 4040 MHz, vertical polarization. It's available in Alaska and Hawaii on an MPEG-2 digital signal accessed via satellite AMC-7, transponder 18C, 137 degrees west longitude, 4060 MHz, vertical polarization. A Digital Video Broadcast compliant Integrated Receiver Decoder is required for reception. For information about NASA TV, including digital downlink information, visit:

The next space station status report will be issued on Monday, Oct. 10, following the Soyuz landing or earlier if events warrant. For information on the crew's activities aboard the station, future launch dates, and station sighting opportunities from anywhere on the Earth, visit:
