Atlantis ODS and Payload Bay

S135-E-007101 (10 July 2011) --- This picture of Atlantis' payload bay, focusing on the docking mechanism, was photographed by one of four STS-135 crewmembers inside the crew cabin. The orbiter boom sensor system and a portion of the remote manipulator system's robot arm are visible in the frame, exposed during a busy third day in space for the astronauts. The photo was made shortly before the shuttle docked with the International Space Station. Photo credit: NASA
