CAPE CANAVERAL, Fla. - In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida an overhead crane lowers the Lightweight Multi-Purpose Experiment Support Structure Carrier, or LMC, into a payload canister. The canister then will be installed into Atlantis' payload bay. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to lift off on July 8, taking with them the Raffaello multi-purpose logistics module packed with supplies, logistics and spare parts. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing spacecraft 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.

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. Standing inside the Raffaello multi-purpose logistics module, which will be packed with supplies, logistics and spare parts for their mission to the International Space Station, are Mission Specialist Sandy Magnus (left), Commander Chris Ferguson, Mission Specialist Rex Walheim and Pilot Doug Hurley. The purpose of CEIT is for flight crew members to become familiar with the payload they will be working with and delivering to the station. STS-135 also will return a failed ammonia pump module on the Lightweight Multi-Purpose Experiment Support Structure Carrier, or LMC, to help NASA better understand the failure mechanism and improve pump designs for future systems.

CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the Robotic Refueling Mission (RRM) is installed on the Lightweight Multi- Purpose Experiment Support Structure Carrier, or LMC . Technicians are preparing it for its protective cover installation prior to its move into a payload canister. The RRM is being processed to fly aboard space shuttle Atlantis on the STS-135 mission to the International Space Station. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to launch in early July, taking with them the Raffaello multi-purpose logistics module packed with supplies, logistics and spare parts. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing spacecraft and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems.
