CAPE CANAVERAL, Fla. – Before daybreak at the Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida, the team responsible for the handling of space shuttle Discovery receives a briefing at the mate-demate device. Discovery was moved from the Vehicle Assembly Building yesterday, but out-of-parameter winds at the landing facility required that operations to lift it onto a Shuttle Carrier Aircraft be suspended for the day. The device, known as the MDD, is a large gantry-like steel structure used to hoist a shuttle off the ground and position it onto the back of the aircraft, or SCA. The SCA is a Boeing 747 jet, originally manufactured for commercial use, which was modified by NASA to transport the shuttles between destinations on Earth. The SCA designated NASA 905 is assigned to the remaining ferry missions, delivering the shuttles to their permanent public display sites. NASA 905 is scheduled to ferry Discovery to the Washington Dulles International Airport in Virginia on April 17, after which the shuttle will be placed on display in the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center. For more information on the SCA, visit http://www.nasa.gov/centers/dryden/news/FactSheets/FS-013-DFRC.html.
