CAPE CANAVERAL, Fla. – In the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, workers, using overhead cranes, raise a cage over an Approach and Landing Test Assembly (ALTA) pod. The ALTA pod will be lifted for attachment to space shuttle Endeavour on the site once housing the orbital maneuvering system (OMS) pod. The demonstration test is being conducted to ensure the center’s equipment will fit into the hangar at the National Air and Space Museum when installing an ALTA pod on shuttle Enterprise. The pod must be reinstalled on a shuttle for transport on a 747 carrier aircraft. The simulation also tests procedures and timelines necessary to carry out the process. The work is part of the Space Shuttle Program’s transition and retirement processing. Enterprise, which was not equipped for space flight, was built as a test vehicle to demonstrate that the orbiter could fly in the atmosphere and land like an airplane. In 1985, Enterprise was ferried from the Kennedy Space Center to Dulles Airport, Washington, D.C., and became the property of the Smithsonian Institute. Enterprise will be moved from the Smithsonian Institution National Air and Space Museum's Steven F. Udvar-Hazy Center in Chantilly, Va., to the Intrepid Sea, Air and Space Museum in New York.

S79-35236 (23 July 1979) --- The space shuttle orbiter 101 Enterprise is seen in this high angle view as it is being moved from Pad A, Launch Complex 39 at the Kennedy Space Center (KSC) to the Vehicle Assembly Building (VAB). Though only 3.5 miles separate the launch pad and the VAB, the journey of the orbiter, its solid rocket boosters and external tank takes more than 11 hours. The move back to the VAB represents the end of several weeks of fit and function checks performed on the vehicle, prepatory to eventual launch readiness of the first actual flight vehicle in the orbiter flight test (OFT) series -- the Columbia. The SRB/ET/Enterprise cluster will soon be taken apart inside the VAB and the orbiter will be taxied back to the Palmdale, California manufacturing facility of Rockwell International.

Enterprise was the first orbiter built in the Shuttle fleet and was used to conduct the Approach and Landing Test Program before the first powered Shuttle flight. After the tile installation is complete, the sections will be transferred to the Southwest Research Institute for testing requested by the Columbia Accident Investigation Board.
