EXP 9 - Gyroscope Brought Back On Line

* Gyroscope Brought Back On Line 
The Expedition 9 crewmembers aboard the International Space Station 
received good news before a holiday weekend, when Mission Control 
informed them that a vital piece of Station equipment was brought back 
on line. Control Moment Gyroscope 2 (CMG 2) was fully operational Friday 
morning, two days after a spacewalk restored its power supply.

"That's great," NASA ISS Science Officer Mike Fincke replied to Mission 
Control when hearing the news. "Congratulations to you guys on the 
ground -- you guys put in so many hours to make this spacewalk possible."

Expedition 9 Commander Gennady Padalka and Fincke replaced a failed 
circuit breaker during a 5-hour, 40-minute spacewalk Wednesday. The 
gyroscope now joins two others in controlling the Station's orientation 
during normal operations.

On Friday, the crewmembers performed clean-up tasks, including hanging 
the Russian Orlan-M spacesuits out to dry, stowing tools and conducting 
a follow-up conference with spacewalk specialists. Saturday their sleep 
shift schedule reverts to normal as they start a three-day weekend to 
observe the U.S. Independence Day holiday Monday.
