At NASA's Kennedy Space Center pod awaits installation on Discovery in Orbiter Processing Facility 1.

At NASA’s Kennedy Space Center in Florida, an orbital maneuvering system (OMS) pod awaits installation on space shuttle Discovery in Orbiter Processing Facility-1.

The OMS pod was returned from White Sands Space Harbor in New Mexico where it underwent a complete deservicing and cleaning. The work is part of the Space Shuttle Program’s transition and retirement processing of space shuttle Discovery. The shuttle will go to the Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Va., in April 2012. For more information, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Frankie Martin
