Space Station Operations Return to Normal
All of the equipment and computers systems aboard the International Space
Station are now functioning normally after a minor computer glitch
Wednesday and the failure of a Pump Package Assembly, or PPA, in the
Moderate Temperature Loop on Sunday. The newly installed PPA, a spare
that was aboard the space station, was also started up successfully and
is currently working. 

Expedition Six Commander Ken Bowersox, Flight Engineer Nikolai Budarin
and NASA ISS Science Officer Don Pettit returned to a normal work
schedule Thursday. They conducted sessions with the the Effects of EVA
and Long-Term Exposure to Microgravity on Pulmonary Function, or PuFF,
experiment. Puff research focusses on lung function following spacewalks
and inside the International Space Station, laying the groundwork for
future experiments that are key to understanding and maintaining crew
health during long-duration spaceflights.

Also, troubleshooting efforts for the Microgravity Science Glovebox
continue to show success. MSG data looked good Thursday. The glovebox
tripped a circuit breaker in February. Science operations may resume in
the MSG next week.
