GREENBELT, Md. — NASA’s Robotic Refueling Mission 3 (RRM3) has successfully completed its second set of robotic tool operations on the International Space Station, demonstrating key techniques for transferring cryogenic fluids, used as coolants, propellants, or for life support systems in orbit. These technologies have applications for extending spacecraft life and facilitating exploration to the Moon and Mars.

From October 19-22, RRM3 – with the help of the station’s Dextre robot – connected an 11-foot long hose to a designated cryogen port while simultaneously using an inspection tool to verify the hose connection. This marks the first time that Dextre has had tools in both arms completing RRM3 operations. RRM3 supplied the hose and robotic tools of a future servicer spacecraft, as ...
