CAPE CANAVERAL, Fla. -- Members of the media and Kennedy workers snap photos of shuttle Atlantis as it makes its final planned move from Orbiter Processing Facility-1 to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. The move called "rollover" is a major milestone in processing for the STS-135 mission to the International Space Station. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are expected to launch mid July, taking with them the Raffaello multipurpose logistics module packed with supplies, logistics and spare parts. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing spacecraft and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.
