Payload Mission Manager Joe Delai speaks and lifted into the payload changeout room on the rotating service structure.

On Launch Pad 39A at NASA's Kennedy Space Center in Florida, Payload Mission Manager Joe Delai speaks to media after the payload canister carrying the Raffaello multi-purpose logistics module (MPLM) was delivered to the pad for space shuttle Atlantis' STS-135 mission, and lifted into the payload changeout room on the rotating service structure.

Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to lift off on space shuttle Atlantis July 8, taking with them the MPLM packed with supplies, logistics 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.
