In Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida, workers position shuttle Discovery's right-hand orbital maneuvering system, or OMS, pod onto a transporter. It then will be moved to the Hypergol Maintenance Facility. The removal is part of Discovery's transition and retirement processing. Work performed on Discovery is expected to help rocket designers build next-generation spacecraft and prepare the shuttle for future public display. Photo credit: NASA/Jack Pfaller
