International Space Station Status Report #03-45

Expedition 7 Crew

With a newly arrived Russian Progress cargo vehicle at the aft end of
the Zvezda Service Module awaiting unloading and a just-vacated Pirs
Docking Compartment awaiting their successors, International Space
Station Expedition 7 crewmembers, Commander Yuri Malenchenko and NASA
ISS Science Officer Ed Lu, spent much of Friday doing scheduled
spacesuit maintenance. 

The ISS Progress 12 unpiloted cargo vehicle arrived Saturday with about
5,000 pounds of food, water, equipment and fuel for the ISS. Its docking
port had been vacated a week earlier by ISS Progress 10. It re-entered
the Earth's atmosphere and burned shortly after its Aug. 27 undocking. 

The ISS Progress 11 spacecraft left its Pirs berth Thursday at 2:42 p.m.
CDT for another month alone in orbit, as part of a Russian scientific
experiment. It will then be deorbited with its load of station refuse
and burn in the Earth's atmosphere. The docking port it occupied will in
October welcome the Soyuz TMA-3 spacecraft with Expedition 8 Commander
Mike Foale and Cosmonaut Alexander Kaleri aboard. With them will be
Spaniard Pedro Duque a European Space Agency astronaut who will spend
eight days aboard the orbiting laboratory. He will return to Earth with
the Expedition 7 crew. 

The spacesuit work today by Lu and Malenchenko involved what amounted to
annual maintenance. The work is called a mid-term checkout and included
emptying and refilling the suit's water tank and loops, cycling relief
valves, checking sensors and collecting data, a leak check and running
the suit's fan for two hours to lubricate it. Such maintenance is
required no more than 369 days after the last spacewalk, previous
maintenance or a checkout on the ground. 

Other activities during the week included successful completion by Lu of
two more runs of the Pore Formation and Mobility Investigation
experiment in the Microgravity Science Glovebox of the U.S. laboratory
Destiny. The experiment involves melting a transparent material to see
how bubbles form in the molten material and how they interact with one
another. Researchers hope to gain understanding of molten materials and
the potentially weakening bubbles that can form in them. 

Malenchenko and Lu also continued regular station maintenance activities
and their daily exercise sessions scheduled to mitigate some of the
physiological effects of their extended stay in micorgravity.
