Fill 'er up: Gas-bot Dextre will help install  NASA's Robotic Refueling Mission experiment gear to the International  Space Station.
(Credit: NASA) NASA is set to end the 30-year space shuttle program next month with the final mission of Atlantis, but the craft may help extend the life of satellites orbiting Earth, thanks to a handyman robot. 
Atlantis will carry a unique robotic experiment during the 12-day STS-135 mission to the International Space Station. 
The Robotic Refueling Mission (RRM)  is designed to help figure out what's needed to refuel satellites in  space. As NASA describes it, "RRM is expected to reduce risks and lay  the foundation for future robotic servicing missions in microgravity." 
The experimental platform will attach to the exterior of the ISS, where remote-controlled maintenance robot Dextre  will practice gassing up satellites that are not designed to be  refueled. To accomplish that, it would have to get past the seals that  typically close a satellite's fuel compartment permanently. 
"During the mission, Dextre uses RRM tools to cut and manipulate  protective blankets and wires, unscrew caps and access valves, transfer  fluid, and leave a new cap in place for future refueling activities,"  NASA says on its RRM page. The robot would be able to fuel satellites as  well as perform minor repairs. 
A spacewalking astronaut will transfer the RRM equipment to Dextre's  Enhanced Orbital Replacement Unit Temporary Platform (EOTP). It will  later be moved to the ISS truss with the help of Canadarm2. 
There are many satellites in orbit now that could benefit from a  refueling service, according to NASA. If tests with Dextre go well, a  mission to refuel an actual satellite could happen as early as May 2013,  Space.com quoted agency officials as saying. 
Atlantis, meanwhile, is slated to launch July 8.
