Expedition 7 Crew

The Expedition 7 crew, Commander Yuri Malenchenko and NASA International
Space Station Science Officer Ed Lu, spent their 14th week in space
performing various science experiments, practicing with the Station's
robotic arm and maintaining Station systems. 

On Tuesday, the crew marked the 1,000th day of human occupancy of the
Station with a downlinked video message and a call from the heads of the
five global space agencies that represent the 16 nations of the ISS

During the week, Lu worked with the Coarsening in Solid Liquid Mixtures
(CSLM) experiment in the Microgravity Science Glovebox in the Destiny
Laboratory. That experiment will be continued next week. CSLM is being
used to study a physical process called "coarsening" that can reduce the
strength of metals, such as those in jet engine turbine blades. Lu also
performed a functional check of the Biotechnology Specimen Temperature
Controller, which will be used in a fluid dynamics experiment later in
the Expedition 7 mission. 

Throughout the week, Malenchenko took part in various Russian medical
studies to continue gathering data on the effects of microgravity on the
human body during a long-duration spaceflight. He also worked with the
Russian/German Plasma Crystal-3 (PK-3) experiment, which is being used
to examine fine particles inside an evacuated work chamber that have
been charged and excited by radio frequencies. 

Both crewmembers also took time from their schedules to answer questions
from TV Globo's "Fantastico" show in Sao Paulo, Brazil, and from
teachers participating in the NASA Explorer Schools Program at Ames
Research Center, Calif. 

Throughout the week, Malenchenko and Lu continued regular maintenance
activities on the Station and performed daily physical exercises to
minimize the long-term effects of living in microgravity. 

The Expedition 7 crewmembers, who arrived at the station April 28, are
scheduled to return to Earth in their Soyuz TMA-2 spacecraft on Oct. 28.
They will be replaced by the Expedition 8 crew, U.S. astronaut Michael
Foale and Russian cosmonaut Alexander Kaleri. 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. 

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. 8, or sooner
if events warrant.
