ISS Control Moment Gyroscope Failing?
Word that one of the CMGs isn’t working well is not a good thing:
[The CMG that failed in 2002] was replaced with a spare during the first post-Columbia shuttle mission in 2005. No other backups are available, but the failed gyro currently is being refurbished. Depending on what happens with CMG-3, the refurbished gyro could be added to an upcoming mission.
Emphasis is mine.
