NASA | Behind the Scenes at the Satellite Servicing Center and Robotic Lab

NASA's highly anticipated Robotic Refueling Mission (RRM) began operations on the International Space Station with the Canadian Dextre robot and RRM tools March 7-9, 2012, marking important milestones in satellite-servicing technology and the use of the space station robotic capabilities.
A joint effort between NASA and the Canadian Space Agency (CSA), RRM is an external station experiment designed to demonstrate the technologies, tools, and techniques needed to robotically service and refuel satellites in orbit, especially those not built with servicing in mind. RRM represents the first time the space station's Dextre robot is used for technology research and development, moving it beyond robotic maintenance of the orbiting superstructure.
