International Space Station Status Report #03-49

Expedition 7 Crew

The week for Commander Yuri Malenchenko and NASA International Space
Station Science Officer Ed Lu was filled with work on various science
experiments and routine maintenance aboard the orbiting laboratory. 

Lu spent much of his time inside the U.S. Destiny laboratory setting up
and performing science investigations. He installed a protein crystal
growth experiment in the Microgravity Science Glovebox that will be
operated by European Space Agency Astronaut Pedro Duque of Spain, who
will arrive at the Station Oct. 20 with the oncoming Expedition 8 crew.
Duque, who is flying to the Station on a Soyuz spacecraft under a
commercial contract between ESA and the Russian Aviation and Space
Agency, will return to Earth Oct. 28 with Malenchenko and Lu. 

A soldering experiment that is providing insight into how solder
connections in space can be improved and an automated Earth observation
camera system were also set up by Lu in the lab. This week, Lu worked
with the Fluid Dynamics Investigation, which scientists believe will
help alleviate problems with mixing samples for tissue growth
experiments. Those samples are housed in a bioreactor, which allows
three-dimensional tissue cells, like those in the human body, to grow. 

As part of an educational project to help inspire the next generation of
explorers, Lu used well-known objects to videotape center-of-mass
demonstrations. Using a screwdriver, a compact disc player, a cassette
tape and a ruler, he showed how these objects behave differently without
gravity. The video will be distributed to science centers across the
country for use in lesson plans and future exhibits. 

Malenchenko conducted science experiments in the Russian segment of the
Space Station. They included biomedical studies of the human body in
microgravity as well as observations of thunderstorm activity, the
world's ocean biology and studies of how space-based predictions of
man-made disasters could be made. 

The maintenance activities onboard the Station included Malenchenko
inspecting fire sensors in the Zarya control module and checking systems
in the Pirs Docking Compartment. Both Lu and Malenchenko did monthly
maintenance on the treadmill and resistive exercise equipment. 

Lu also configured the U.S. laptop computers so the Expedition 8 crew
can begin using them when it arrives. The oncoming resident crew,
Commander and NASA ISS Science Officer Mike Foale and Flight Engineer
Alexander Kaleri, along with Duque, are set to launch from the Baikonur
Cosmodrome in Kazakhstan at 12:37 a.m. CDT Oct. 18.

launch dates, as well as Station sighting opportunities from anywhere on
the Earth, is available on the Internet at:
