Here is NASA's report on it (from ISS station status report Number 7):: "After a successful preplanned attitude transition maneuver Tuesday, return of attitude control was interrupted when one of the Control Moment Gyroscopes (CMG) became saturated and lost its ability to control the Station's orientation. Attitude control was automatically taken over by the Russian Attitude Control System thrusters for about one orbit, using about 14 kilograms of propellant. The CMG saturation was the result of an incorrect ground command. The ground team recognized the source of the error and issued the command to properly reposition the CMG. The CMGs then resumed control and the thrusters were turned off. The crew's workday was unaffected by the events.
