In Orbiter Processing Facility-1 at NASA's Kennedy Space Center in Florida, the "vehicle powered" sign is turned off following the final power down of space shuttle Discovery during Space Shuttle Program transition and retirement activities. "Power down" followed the final closure of Discovery's payload bay doors.
Discovery is being prepared for public display at the Smithsonian’s National Air and Space Museum Steven F. Udvar-Hazy Center in Chantilly, Va., in 2012. For more information, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Jim Grossmann
