The Robotic Refueling Mission (RRM) is a NASA technology demonstration mission that was launched in 2011 and successfully completed in 2013 from the International Space Station (ISS).
The purpose is to demonstrate the technology and tools to refuel satellites in orbit by robotic means. After the proof of concept, the long-term goal of NASA is to transfer the technology to the commercial sector.
A step II mission is scheduled during the summer of 2013 and early 2014.
RRM is designed with four tools, each with electronics and two cameras and lights. Additionally, it has pumps and controllers and electrical systems such as electrical valves and sensors.
