SSRMS

iss050e056301 (3/8/2017) --- A view of the Space Station Remote Manipulator System (SSRMS) during Robotic Refueling Mission-Phase 2 (RRM-P2) operations. NASA's Robotic Refueling Mission (RRM) is an external International Space Station (ISS) investigation that demonstrates and tests the tools, technologies and techniques needed to robotically refuel, repair, and upgrade satellites in space, especially satellites that were not designed to be serviced. A joint effort between NASA and the Canadian Space Agency (CSA), RRM is the first in-orbit attempt to test robotic refueling and servicing techniques for spacecraft not built with in-orbit servicing in mind.
