CAPE CANAVERAL, Fla. -- Space shuttle Atlantis' STS-135 crew address the media on the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. From left are Mission Specialist Sandy Magnus, Pilot Doug Hurley, Commander Chris Ferguson and Mission Specialist Rex Walheim. While at Kennedy, Atlantis' crew will participate in a launch countdown dress rehearsal called the Terminal Countdown Demonstration Test (TCDT) and related training in preparation for the upcoming STS-135 mission. The STS-135 crew members are targeted to lift off on July 8, taking with them the Raffaello multi-purpose logistics module packed with supplies, logistics and spare parts to the International Space 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.
