CAPE CANAVERAL, Fla. -- STS-135 Commander Chris Ferguson (left), Pilot Doug Hurley and Closeout Crew Lead Travis Tod Thompson with United Space Alliance, check out the plaque that will be placed in front of space shuttle Atlantis' hatch in the White Room at NASA Kennedy Space Center's Launch Pad 39A. An access arm supports the White Room that is in place against the shuttle which provides entry to the crew compartment. The astronauts are at Kennedy to participate in a launch countdown dress rehearsal called the Terminal Countdown Demonstration Test (TCDT) and related training. Atlantis and its crew are targeted to lift off July 8, taking with them the Raffaello multi-purpose logistics module packed with supplies 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.
