In the Space Station Processing Facility, technicians prepare a Control Moment Gyroscope (CMG), attached to the Small Adapter Plate Assembly, to be lifted to the Lightweight Multi-Purpose Experiment Support Structure Carrier for flight. The CMG will launch aboard Space Shuttle Discovery on Return to Flight mission, STS-114 to the Space Station. The CMGs provide altitude control for the outpost keeping it properly oriented toward the Sun without the use of rocket fuel. During the STS-114 mission, astronauts will perform a spacewalk to replace an inoperable CMG. Four CMGs are mounted on the Z1 Truss of the Station. The launch window for STS-114 is May 15 to June 3, 2005.
