CAPE CANAVERAL, Fla. -- The Closeout Crew helps STS-135 Pilot Doug Hurley prepare to enter space shuttle Atlantis from the White Room of Launch Pad 39A at NASA's Kennedy Space Center in Florida. Hurley is one of the final four astronauts to launch aboard a space shuttle. He is a colonel in the U.S. Marine Corps with one shuttle mission under his belt -- STS-127 aboard Endeavour. STS-135 is scheduled to lift off at 11:26 a.m. EDT on July 8 for a mission to the International Space Station. STS-135 will deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts for the International Space Station. Atlantis also will fly the Robotic Refueling Mission experiment that will investigate the potential for robotically refueling existing satellites in orbit. In addition, Atlantis will return with 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.
