International Space Station Status Report #03-37

Expedition 7 Crew

The Expedition 7 crew, Commander Yuri Malenchenko and NASA International
Space Station Science Officer Ed Lu, continued work this week with
unique microgravity science experiments and maintained the operating
systems of the orbiting lab. 

On Monday, the crewmembers passed the 100-day mark on orbit since their
launch to the Station April 26. The crew is scheduled to return to Earth
in late October aboard the same Soyuz vehicle they arrived in. The
Expedition 8 crew, U.S. astronaut 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 European Space Agency astronaut Pedro Duque of
Spain. Duque will then return to Earth with the Expedition 7 crew after
completing more than a week of science activities aboard the Station.
Foale, Kaleri and Duque will talk to reporters about their upcoming
mission during a news conference at 3 p.m. EDT, Thursday, Aug. 14, at
the Johnson Space Center, Houston, which will be broadcast on NASA TV. 

Throughout the week aboard the ISS, Lu worked with a run of the
Coarsening of Solid-Liquid Mixtures-2 (CSLM-2) experiment in the
Microgravity Science Glovebox. CSLM-2 is studying how the strength of
metals, such as those used in jet engine turbine blades, is reduced
during a process called coarsening. Malenchenko worked with Earth
observation experiments and wrapped up a Russian agriculture experiment
studying the growth of plants in space. He saved the data from the
Rasteniya-2 experiment in preparation for its return to Earth. 

Tuesday, the Station operating system briefly shifted into "survival
mode" when the on-board computers did not recognize both thermal system
loops in the Russian segment. Nonessential systems were automatically
turned off, but flight controllers and payload controllers worked with
the crew to reactivate the operating and payload systems without major
impacts to operations or science. 

Lu and Malenchenko resized a spare U.S. spacesuit to fit Lu.
Malfunctions in Lu's original suit were found during a test earlier in
the mission and the larger modular-designed suit was easily adjusted to
fit Lu in the event he needs to conduct a U.S. airlock-based spacewalk.
Initially, during the fit check of the suit, the cooling system did not
function correctly but began working later in the test. Spacesuit
experts will continue to troubleshoot the issues with both spacesuits. 

This week, Malenchenko used oxygen from the Progress cargo vehicle
docked to the aft of the Zvezda Service Module to repressurize the
Station. The extra oxygen is being used before the spacecraft is
undocked later this month to make room for a new Progress resupply craft
scheduled for launch to the Station Aug. 28 (U.S. time). 

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:

Details on Station science operations can be found on an Internet site
administered by the Payload Operations Center at NASA's Marshall Space
Flight Center in Huntsville, Ala., at:

The next ISS status report will be issued on Friday, Aug. 15, or sooner
if events warrant.
