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
