After demate from the shuttle carrier aircraft, or SCA, Atlantis begins its trek from Kennedy Space Center's Shuttle Landing Facility to the Orbiter Processing Facility. The orbiter will undergo processing for its next launch, mission STS-122 in December. Visible on Atlantis is the tail cone that covers and protects the main engines during the ferry flight. Atlantis arrived at Kennedy Space Center 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. Atlantis landed at Edwards Air Force Base in California on June 22 to end mission STS-117. Photo credit: NASA/George Shelton.
