CAPE CANAVERAL, Fla. -- Space shuttle Atlantis' STS-135 crew participates in a crew equipment interface test, or CEIT, in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. The purpose of CEIT is for flight crew members to become familiar with the hardware and tools they will work with in space. Here, a technician shows Mission Specialist Rex Walheim the Lightweight Multi-Purpose Experiment Support Structure Carrier, or LMC, which will be used to return a failed ammonia pump module from the International Space Station. Crews on Earth will examine the failure mechanism to help NASA improve pump designs for future systems. STS-135 also will carry the Raffaello multi-purpose logistics module packed with supplies, logistics and spare parts. STS-135, targeted to launch June 28, 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.
