It's a space shuttle face-off!

Space Shuttles Atlantis, left, and Endeavour face each other as the Endeavour backs out of the Orbiter Processing Facility and Atlantis is moved out of the Vehicle Assembly Building Aug. 16, in Cape Canaveral, Fla. The Endeavour will be moved to the California Science Center as a permanent exhibit and the Atlantis will be kept at the Kennedy Space Center Visitor Complex.
