International Space Station Status Report #03-38

Expedition 7 Crew

The Expedition 7 crew, Commander Yuri Malenchenko and NASA International
Space Station Science Officer Ed Lu, this week conducted science
experiments, maintenance activities and prepared for the upcoming
departure and arrival of Progress cargo and Soyuz vehicles. 

Lu talked with former Station Science Officer Don Pettit to help locate
hardware for the Pore Formation and Mobility Investigation (PFMI) that
Lu installed in the Microgravity Science Glovebox Monday. Lu was
scheduled to begin science operations with PFMI this week, but was
unable to locate an essential cable to complete the installation.
Pettit's ideas as to where he left the cable were fruitful. With the
cable now installed, Lu can begin a run of the experiment next week. 

Troubleshooting continued this week with the two U.S. spacesuits
experiencing cooling system issues onboard. Lu and Malenchenko executed
a procedure to closely inspect valves and filters for water circulation
in the system of the first suit Lu tried on during the mission.
Investigations of the cooling system of the spare suit he re-sized last
week are still underway. Even though they are not scheduled to conduct a
spacewalk during this mission, Lu and Malenchenko could use the Russian
Orlan spacesuits to conduct a spacewalk, if needed, since Lu does not
currently have a working U.S. spacesuit to wear. 

This week, Malenchenko continued to use oxygen from the Progress cargo
vehicles docked to the aft of the Zvezda Service Module and to the Pirs
Docking Compartment to repressurize the Station. The extra oxygen is
being used before the two spacecraft are undocked, taking with them
trash and used supplies to burn up in the Earth's atmosphere. The
Progress docked to Zvezda will undock Aug. 27 to make room for a new
Progress resupply craft scheduled for launch to the Station Aug. 28
(U.S. time). The Progress docked to Pirs will undock Sept. 4 to make
room for the Soyuz TMA-3 spacecraft scheduled to arrive Oct. 20 with the
Expedition 8 crew and European Space Agency astronaut Pedro Duque. 

Expedition 8 Commander Michael Foale and Russian cosmonaut Alexander
Kaleri, will replace the Expedition 7 crew. Foale and Kaleri are
scheduled to launch to the Station Oct. 18 aboard a Russian Soyuz
spacecraft, along with Duque who will return to Earth with the
Expedition 7 crew after completing more than a week of science
activities aboard the Station on Oct. 28. 

Information on the crew's continuing activities on the Space Station,
future launch dates and Station sighting opportunities from anywhere on
Earth is available at:

The next ISS status report will be issued on Friday, Aug. 22, or sooner
if events warrant.
