Technicians move a system that will investigate the potential for robotically refueling existing spacecraft in orbit from a processing lab to a high bay in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. The move prepares the system for its lift into the Lightweight Multi-Purpose Experiment Support Structure Carrier (LMC), which will carry it into orbit. Called the Robotic Refueling Mission (RRM), the system will be processed to fly aboard space shuttle Atlantis on the STS-135 mission to the International Space Station.
Also going up will be the Raffaello multipurpose logistics module packed with supplies, logistics and spare parts. The mission also will return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135, targeted to launch June 28, 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.
