CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, technicians in the payload changeout room have maneuvered space shuttle Atlantis' cargo, the Raffaello multi-purpose logistics module (MPLM) into the shuttle's payload bay using the payload ground-handling mechanism at Launch Pad 39A. The rotating service structure that protects the shuttle from the elements and provides access has been moved back into place. STS-135 Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandy Magnus and Rex Walheim are targeted to lift off on Atlantis July 8, taking with them the MPLM packed with supplies, logistics and spare parts to the 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.

The antenna, which resembles a mini-satellite dish, transmits audio, video and data between Earth and the shuttle. Next, the clamshell doors of the payload bay will close completely in preparation for its move to the Vehicle Assembly Building. Atlantis is 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

CAPE CANAVERAL, Fla. -- A canister, carrying the Raffaello multi-purpose logistics module (MPLM) for space shuttle Atlantis' STS-135 mission to the International Space Station, arrives at Launch Pad 39A at NASA's Kennedy Space Center in Florida. The canister will be lifted to the payload changeout room. The payload ground-handling mechanism then will be used to transfer Raffaello out of the canister into Atlantis' payload bay. Next, the rotating service structure that protects the shuttle from the elements and provides access will be rotated back into place. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to lift off on Atlantis July 8, taking with them the MPLM packed with supplies, logistics and spare parts to the 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.

CAPE CANAVERAL, Fla. -- At Launch Pad 39A at NASA's Kennedy Space Center in Florida, space shuttle Atlantis' payload bay doors are closed for flight. The payload arrived at the pad June 16 for installation into Atlantis and includes the Raffaello multi-purpose logistics module packed with supplies and spare parts for 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. Atlantis and its crew are scheduled to lift off at 11:26 a.m. EDT July 8. 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. -- Sunrise at NASA's Kennedy Space Center in Florida finds space shuttle Atlantis on Launch Pad 39A after the payload canister carrying the Raffaello multi-purpose logistics module (MPLM) was lifted into the payload changeout room. The payload ground-handling mechanism then will be used to transfer Raffaello out of the canister into Atlantis' payload bay. Next, the rotating service structure that protects the shuttle from the elements and provides access will be rotated back into place. 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.

CAPE CANAVERAL, Fla. -- In Orbiter Processing Facility-2 (OPF-2) at NASA’s Kennedy Space Center in Florida, the Raffaello multi-purpose logistics module is secured in the payload canister, after a special payload removal device was used to remove it from Atlantis’ cargo bay. Raffaello will then be readied for transport to the Space Station Processing Facility where its contents will be unloaded. Atlantis completed NASA’s final space shuttle mission, STS-135, after landing at the center’s Shuttle Landing Facility, July 21, 2011, at 5:57 a.m. EDT. Following removal of all payloads in Atlantis’ cargo bay, workers will begin to prepare the spacecraft for eventual permanent display at the Kennedy Space Center Visitor Complex.
