International Space Station Status Report #03-46 
4 p.m. CDT Friday, Sept. 12, 2003 
Expedition 7 Crew

The unloading of nearly three tons of new supplies from a Progress cargo
vehicle began in earnest this week aboard the International Space
Station. Commander Yuri Malenchenko and NASA ISS Science Officer Ed Lu
spent time each day unpacking, cataloging and stowing the equipment. 

The ISS Progress 12 (12P) vehicle brought food, fuel and equipment to
the Station Aug. 30,U.S. time. This week, the thrusters on 12P were
successfully tested and can be used to increase the Station's altitude
when necessary. Also, nitrogen from the cargo vehicle's gas tanks was
used to add pressure to the atmosphere inside the Station, while oxygen
repressurization from 12P will occur later. 

Among the new supplies were two canisters for the Resistive Exercise
Device weightlifting machine, which Lu installed Friday. Coincidentally,
Lu had trouble adjusting the resistance on one of the previous canisters
Wednesday. He removed that set and will work to repair the problematic
canister next week so that the new ones that arrived on Progress can be
reserved for the next crew to live aboard the Station. 

Friday, flight controllers in Mission Control Houston worked on the
communication link between the Space Station and control centers in
Houston, Moscow and Huntsville, Ala. The crewmembers noticed they were
barely able to hear voice calls from the capcoms, or spacecraft
communicators, from each of the centers. The problem was narrowed down
to equipment in Houston that relays the audio to the Station from all
the control centers. Engineers will continue to troubleshoot the issue
with the hardware. In the meantime, the audio link to the Station has
been restored to normal levels by temporarily bypassing that specific
piece of hardware. 

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 Sept. 19, or sooner if events
