KENNEDY SPACE CENTER, FLA. -- The shuttle carrier aircraft, or SCA, and its piggyback passenger Atlantis are poised to be towed into the mate/demate device, in the foreground. The device will lift the orbiter and put it back on the ground. After a three-day, cross-country trip, the orbiter/SCA duo touched down at 8:27 a.m. EDT. The SCA is a modified Boeing 747 jetliner. Atlantis landed at Edwards Air Force Base in California to end mission STS-117. The return to KSC began July 1 and included several stops across the country for fuel. The last stop was at Ft. Campbell in Kentucky. Weather conditions over the last leg postponed the return trip until July 3. After demate, Atlantis will then be towed to the Orbiter Processing Facility to begin processing for its next launch, mission STS-122 in December. Photo credit: NASA/Kim Shiflett

Campbell in Kentucky. Weather conditions over the last leg postponed the return trip until July 3. Atlantis will be removed from the back of the SCA via the mate/demate device at the SLF. It will then be towed to the Orbiter Processing Facility to begin processing for its next launch, mission STS-122 in December. Photo credit: NASA/Kim Shiflett

The Shuttle Carrier Aircraft with orbiter Columbia riding piggyback taxis toward the mate/demate device at the KSC Shuttle Landing Facility. At the MDD, Columbia will be lifted off the SCA and towed to the Orbiter Processing Facility bay 1. Columbia’s ferry flight began in California March 1. Unfavorable weather conditions kept it on the ground at Dyess AFB, Texas, until it could return to Florida. It landed temporarily at the CCAFS Skid Strip until Atlantis, which had already landed at the SLF, could be transferred. Columbia is returning from a 17-month-long modification and refurbishment process as part of a routine maintenance plan. The orbiter will next fly on mission STS-107, scheduled Oct. 25

CAPE CANAVERAL, Fla. -- Before dawn, at the Shuttle Landing Facility, or SLF, at NASA's Kennedy Space Center in Florida, space shuttle Endeavour is suspended by a sling under the mate/demate device. The shuttle carrier aircraft, or SCA, has rolled away. Endeavour, which retains the tail cone that covers and protects the main engines during the ferry flight, will be lowered onto the ground. The SCA carried the shuttle piggyback from California, where Endeavour landed Nov. 30 to end the STS-126 mission. After Endeavour is on the ground, it will be towed via the two-mile tow-way from the SLF by a diesel-powered tractor to the Orbiter Processing Facility where it will begin preparations for its next mission, STS-127, targeted for May 2009.

CAPE CANAVERAL, Fla. -- The shuttle carrier aircraft, or SCA, and its piggyback passenger space shuttle Endeavour are poised to enter the mate/demate device at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. The device 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

CAPE CANAVERAL, Fla. – On the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, space shuttle Atlantis is moved away from the mate/demate device where it was separated from the Shuttle Carrier Aircraft, or SCA. Atlantis will be towed to Orbiter Processing Facility 1. Covering the rear of Atlantis is a tail cone, which protects the aft engine area and provides a more efficient aeronautical dimension during its piggyback flight. After its May 24 landing at Edwards Air Force Base in California, which concluded its STS-125 mission, the modified Boeing 747 SCA carried the shuttle on a two-day ferry flight from Edwards to Kennedy beginning June 1. Atlantis' next assignment is the STS-129 mission, targeted to launch in November 2009. Photo credit: NASA/Jack Pfaller

A sling in the device will lift the shuttle away from the shuttle carrier aircraft, or SCA, underneath. The SCA carried the shuttle piggyback from California, where Endeavour landed Nov. 30 to end the STS-126 mission.

CAPE CANAVERAL, Fla. – At Edwards Air Force Base in California, a sling in the mate/demate device suspends space shuttle Atlantis above the ground. A Shuttle Carrier Aircraft, or SCA, will be moved underneath and Atlantis bolted to the top of the modified Boeing 747. A tail cone, which protects the aft engine area and provides a more efficient aeronautical dimension during its piggyback flight, can be seen. Atlantis landed at Edwards on May 24, which concluded mission STS-125, after two landing opportunities at Kennedy were waved off due to weather concerns. Atlantis is being returned to Florida on a ferry flight on the SCA. Atlantis' next assignment is the STS-129 mission, targeted to launch in November 2009. Photo credit: NASA/Ben Smegelsky

This view of Atlantis at the mate/demate device at KSC’s Shuttle Landing Facility shows the tail cone that orbiters use when being carried piggyback on ferry flights atop a Shuttle Carrier Aircraft. The tail cone protects the aft engine area and provides a more efficient aeronautical dimension during flight. Atlantis returned from California atop the SCA after its Feb. 19 landing at Edwards Air Force Base concluding mission STS-98. The ferry flight began March 1; unfavorable weather conditions kept it on the ground at Altus AFB, Okla., until it could return to Florida. Atlantis will be transported to the Orbiter Processing Facility to prepare it for mission STS-104, the 10th construction flight to the International Space Station, scheduled to launch June 8
