Expedition 11 Crew

The residents of the International Space Station this week unloaded cargo
delivered to them last month by Discovery's astronauts, prepared for the
arrival of more supplies and repaired a key component of the outpost's
environmental control system.

In the fifth month of their six-month mission, Expedition 11 Commander
Sergei Krikalev and NASA Flight Engineer and Science Officer John Phillips
completed the unpacking of cargo bags transferred to the Station's Zarya
module from the Shuttle Discovery three weeks ago. They planned to unload
other bags stowed in the Unity and Zvezda modules in the days ahead. All of
the unpacked items were entered into the Station's computerized inventory
system.

On Friday, the crew will begin to fill the ISS Progress 18 resupply craft
docked at the aft end of Zvezda with trash and unneeded gear. The Progress
craft will undock from the complex at 5:23 a.m. CDT Sept. 7. It will be
commanded to fire its engines to enter the Earth's atmosphere and burn up
over the Pacific Ocean.

That will set the stage for the 8:08 a.m. CDT Sept. 8 launch of the ISS
Progress 19 cargo vehicle from the Baikonur Cosmodrome in Kazakhstan. EDT.
Filled with more than 2.5 tons of food, fuel, oxygen, water and spare parts,
Progress 19 will automatically dock to the Station at 9:50 a.m. CDT Sept.
10. The docking will be broadcast live on NASA Television.

Among the items to be carried aboard Progress 19 is a new liquids unit for
the Russian Elektron oxygen-generation system that failed several months
ago. The liquids unit circulates water through the Elektron, separating it
into hydrogen and oxygen through electrolysis. The hydrogen is then vented
overboard and the oxygen is circulated into the atmosphere for breathing.
While Elektron has been inactive, oxygen from the Progress 18 tanks has been
used to repressurize the cabin atmosphere. Multiple sources of oxygen are
available for use by the crew with ample supplies available.

On Tuesday, Krikalev repaired the Vozdukh carbon dioxide removal system by
replacing a faulty valve. Vozdukh shut down late last week, prompting the
temporary use of another air-scrubbing system, the U.S. Carbon Dioxide
Removal Assembly (CDRA) in the Destiny Laboratory.

Also on Tuesday, Krikalev and Phillips took time to discuss life and work
aboard the Station with students gathered at the Cincinnati Museum Center in
Ohio. The educational event was broadcast to schools in the Ohio Valley.
On Wednesday, Phillips replaced a failed laptop computer used to house
inventory and information about the Station's medical supplies. The computer
experienced problems three weeks ago during Discovery's visit.

They also spent 90 minutes Wednesday practicing emergency procedures during
an exercise that simulated the rapid depressurization of the Station's
cabin. Rehearsals of this nature are conducted periodically to maintain
proficiency for the crew and flight controllers.

In addition to exercise and routine maintenance, the crewmembers stowed
spacewalking tools they used last week during their excursion outside the
Pirs Docking Compartment to retrieve experiments and hardware. The spacewalk
was the only one planned for Expedition 11.

Information on the crew's activities aboard the Space Station, future launch
dates, as well as Station sighting opportunities from anywhere on the Earth,
is available on the Internet at:

The next Station status report will be issued on Thursday, Sept. 1, or
earlier if events warrant.
