CAPE CANAVERAL, Fla. -- The STS-135 crew members arrived at NASA Kennedy Space Center's Shuttle Landing Facility at about 2:30 p.m. EDT on July 4 for final preparations for space shuttle Atlantis' STS-135 mission to the International Space Station. From left are Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandy Magnus and Rex Walheim. Atlantis and its crew are slated to lift off on July 8, taking with them the Raffaello multi-purpose logistics module packed with supplies and spare parts to the station. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing satellites 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.
