CAPE CANAVERAL, Fla. – Under a dimming sky, space shuttle Atlantis, atop a Shuttle Carrier Aircraft, or SCA, is framed between two Shuttle Training Aircraft on the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. The SCA is a modified Boeing 747 jetliner. The SCA and Atlantis are being towed the mate/demate device (at far right) on the Shuttle Landing Facility where Atlantis will be lifted from the SCA and placed on the ground. Atlantis returned from California atop the SCA after its May 24 landing at Edwards Air Force Base, concluding mission STS-125. The ferry flight from Edwards Air Force Base began June 1. Atlantis' next assignment is the STS-129 mission, targeted to launch in November 2009. Photo credit: NASA/Jack Pfaller

KENNEDY SPACE CENTER, FLA. - Space Shuttle Discovery, atop a modified Boeing 747 Shuttle Carrier Aircraft (SCA), is on its final approach to land on runway 15 at NASA Kennedy Space Center's Shuttle Landing Facility (SLF) at about 10:00 a.m. EDT. The cross-country ferry flight became necessary when two days of unfavorable weather conditions at KSC forced Discovery to land on runway 22 at Edwards Air Force Base, Calif., on Aug. 9 following mission STS-114. On the return trip, stops were made at Altus Air Force Base, Okla., and Barksdale Air Force Base, La., where Discovery stayed for two nights. The SCA and Discovery will be towed to the Mate_Demate Device at the SLF where a crane will lift Discovery from the SCA and place it on solid ground. Discovery will then be towed to the Orbiter Processing Facility where preparations will begin for its next flight, STS-121.

On the return trip, stops were made at Altus Air Force Base, Okla., and Barksdale Air Force Base, La., where Discovery stayed for two nights. The SCA and Discovery will be towed to the Mate_Demate Device at the SLF where a crane will lift Discovery from the SCA and place it on solid ground. Discovery will then be towed to the Orbiter Processing Facility where preparations will begin for its next flight, STS-121.

CAPE CANAVERAL, Fla. – NASA's Shuttle Carrier Aircraft, or SCA, rolls toward space shuttle Endeavour, suspended in the mate-demate device at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. The shuttle will be lowered and connected to the top of the SCA with the aid of the device. The shuttle has been fitted with an aerodynamic tailcone for its upcoming ferry flight. The SCA, a modified 747 jetliner, will fly Endeavour to Los Angeles where it will be placed on public display at the California Science Center. This is the final ferry flight scheduled in the Space Shuttle Program era. For more information on the shuttles' transition and retirement, visit http://www.nasa.gov/transition.

KENNEDY SPACE CENTER, FLA. -- On the KSC Shuttle Landing Facility, workers supervise the movement of the sling above the orbiter Atlantis. The sling will be attached and lift the orbiter away from the shuttle carrier aircraft (SCA) underneath. The SCA carried the orbiter piggyback from California. Atlantis landed at Edwards Air Force Base in California on June 22 to end mission STS-117. It returned to Kennedy atop the SCA on July 3 after a three-day, cross-country flight due to fuel stops and weather delays. Touchdown was at 8:27 a.m. EDT. Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. -- The shuttle carrier aircraft, or SCA, and its piggyback passenger space shuttle Endeavour stop on the parking apron of the Shuttle Landing Facility runway at NASA's Kennedy Space Center in Florida after landing. The SCA will be towed into the mate/demate device that will lift the shuttle and put it back on the ground. After making the three-day trip from California, touchdown at Kennedy was at 2:44 p.m. EST. The SCA is a modified Boeing 747 jetliner. Endeavour landed at Edwards Air Force Base in California Nov. 30 to end mission STS-126. The return to Kennedy began Dec. 8 and took four days after stops across the country for fuel. The last stop was at Barksdale Air Force Base in Shreveport, La. Weather conditions en route and in Florida postponed the landing at Kennedy until Dec. 12. Photo credit: NASA/Kim Shiflett
