The Expedition 26 crew photographed the aft portion of Discovery’s main engines, part of the cargo bay, vertical stabilizer and orbital maneuvering system pods during a survey of the vehicle’s approach prior to its docking with the International Space Station. As part of the survey and part of every mission’s activities, Discovery performed a back-flip for the rendezvous pitch maneuver. The image was photographed with a digital still camera, using a 400mm lens at a distance of about 600 feet (180 meters). Image Credit: NASA
