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.
