CAPE CANAVERAL, Fla. -- At Launch Pad 39A at NASA's Kennedy Space Center in Florida, space shuttle Atlantis' STS-135 crew continue their emergency exit training in a bunker near the catch nets for the slidewire baskets at the base of the pad. The bunker would provide a safe haven for the astronauts if evacuation of the pad were required. From right are Pilot Doug Hurley (red cap), Mission Specialists Sandy Magnus and Rex Walheim, and Commander Chris Ferguson. 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.
