ISS Crew Performs Spacesuit Demonstration
The Expedition Six crew performed a demonstration using U.S. spacesuits
and worked on a Russian oxygen generator before enjoying a half-day off
aboard the International Space Station. 

Expedition Six Commander Ken Bowersox and NASA ISS Science Officer Don
Pettit suited up in U.S. spacesuits inside the Quest Airlock to
demonstrate techniques to be used in donning the suits if only two
crewmembers are present on the space station. Flight Engineer Nikolai
Budarin performed scheduled maintenance on the Russian Elektron oxygen
generator. The off-duty time allowed the crew to observe the Russian
holiday Defenders' Day.

Expedition Six Crew

The Expedition 6 crew marked its 90th day in orbit today. Commander Ken
Bowersox, Flight Engineer Nikolai Budarin and NASA ISS Science Officer
Don Pettit have been in orbit since their launch from the Kennedy Space
Center in Florida on Nov. 23. 

The crew began the week by taking samples of the stationís water supply
to ensure its continued purity. Budarin also started a three-day process
to disinfect equipment in the Russian water supply system using materials
brought to the station aboard the latest Progress resupply craft. Both
activities are part of routine maintenance procedures aboard the station.

During the week, the crew completed a variety of medical tests to ensure
their continued good health and to collect data on how the human body
adapts to microgravity. These included a Russian cardiovascular
experiment and the testing of urine and blood samples. Bowersox and
Pettit also completed a computer-based refresher training related to
their duties as crew medical officers. Station maintenance during the
week included the removal and replacement by Pettit of a remote power
control module in the Destiny laboratory, which contained a bad power
switch that was responsible for powering the video recorder in one of the
robotics workstations. The changeout was successful and the video
recorder is now working. Bowersox performed monthly maintenance on the
cycle ergometer, which the crew uses to maintain their aerobic fitness Ė
the stationís treadmill received its periodic maintenance last weekend.
On Thursday, Bowersox and Pettit conducted an inventory of all the
equipment in the Quest airlock to ensure it matched the data in the
stationís Inventory Management System. 

The loading of new software on the stationís command and control
computers was completed today, as was the loading of the new software
onto the guidance, navigation and control computers. 

On Monday, Bowersox and Pettit plan to don U.S. spacesuits without the
help of Budarin to practice techniques that could be used if only two
crewmembers are present aboard the ISS.
