It may be called the Robotic Refueling Mission (RRM), but NASA built RRM to demonstrate much more than just robotic satellite refueling.
In its second phase, RRM is now moving on to demonstrate how a space robot can complete intermediate tasks required to replenish croygen in the instruments of “legacy” satellites: existing, orbiting spacecraft that were not designed to be serviced. Initial activities to demonstrate this on-orbit capability were completed in March and June 2012 with the aid of the original RRM tools and activity boards.
