On the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, the Shuttle Carrier Aircraft, or SCA, is towed away from the mate/demate device. The SCA was just demated from the shuttle. Atlantis returned from California atop the SCA, a modified Boeing 747, 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
