In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians secure the pump module assembly plate into position onto the Lightweight Multi-Purpose Experiment Support Structure Carrier, or LMC. The module assembly will be used to secure the return of a failed ammonia pump module in shuttle Atlantis' payload bay. Atlantis and its payload are being prepared for the STS-135 mission, which will deliver the Raffaello multipurpose logistics module packed with supplies, logistics and spare parts to the International Space Station. STS-135 is targeted to launch June 28, and will be the last spaceflight for the Space Shuttle Program. Photo credit: NASA/Jack Pfaller
