CAPE CANAVERAL, Fla. – In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians help lift the control moment gyro, or CMG, from its container. 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
