In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the control moment gyroscope, or CMG, is moved toward the small adapter plate assembly in the foreground. The CMG is part of the payload on the STS-129 mission to the International Space Station. On the mission, space shuttle Atlantis also will deliver the orbital spares and replacement parts to sustain the life of the station. Photo credit: NASA/Troy Cryder
