Technicians inspect the Robotic Refueling Mission RRM before installing its protective cover.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians inspect the Robotic Refueling Mission (RRM) before installing its protective cover and later move it into a payload canister.

The RRM is being processed to fly aboard space shuttle Atlantis on the STS-135 mission to the International Space Station.
Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to launch in early July, taking with them the Raffaello multi-purpose logistics module packed with supplies, logistics and spare parts. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing spacecraft 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.
