Space shuttle Atlantis' STS-135 crew members get a close look at some of the equipment they'll use in space.

During the bench review of systems and hardware in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, space shuttle Atlantis' STS-135 crew members get a close look at some of the equipment they'll use in space. The astronauts dressed in clean-room attire, known as "bunny suits" are Commander Chris Ferguson (left) and Mission Specialist Sandy Magnus.

The review is part of 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.
