CAPE CANAVERAL, Fla. -- Inside Orbiter Processing Facility-1 at NASA’s Kennedy Space Center in Florida, a view from inside the tail cone reveals space shuttle Discovery’s three replica shuttle main engines (RSMEs). The tail cone is being installed around the RSMEs for protection. The work is part of the Space Shuttle Program’s transition and retirement processing of shuttle Discovery. Discovery is being prepared for display at the Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Va. For more information, visit http://www.nasa.gov/shuttle.
