NASA is currently developing technology to build Earth-orbiting service stations to extend the life of operating satellites. These stations would provide high-technology gas pumps, robotic mechanics and tow trucks to orbiting satellites. Engineers from the Kennedy Space Center in Florida are participating in this project, particularly by assisting with the hypergolic propellant refueling portion.

Preliminary testing of the Robotic Refueling Mission (RRM) is already occurring at the International Space Station with a technology demonstrator since the equipment arrived last year. The RRM has four tools that are capable to unscrew caps, handle and cut wires, open and close valves, and transfer fluids; imperative tasks to achieve the goal of servicing and refueling an Earth-orbiting satellite.

The RRM has already successfully demonstrated its wire-manipulation capabilities and before the end of this year, it will test its refueling potential. Testing will continue through 2014.

The ultimate goal will be to develop a servicing spacecraft capable of refueling, replacing components, repositioning, remote surveying, and repairing a satellite in space.
