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.

LONGUEUIL, Quebec (CSA PR) — From August 13 to 14, Dextre, Canada’s robotic handyman on the International Space Station, will conduct a demonstration of how robots could refuel satellites and spacecraft to extend their useful lifetimes.

NASA’s Robotic Refueling Mission 3 (RRM3) will use Dextre’s proven ability to perform highly delicate tasks on the International Space Station, to test the hardware and procedures needed to store and transfer cryogenic fluids.

GREENBELT, Md. (NASA PR) — Technology drives exploration for future human missions to the Moon, Mars and beyond. For spacecraft to journey farther and live longer, we’ll need to store and transfer super-cold liquids used for fuel and life support systems in space. In December 2018, the Robotic Refueling Mission 3 (RRM3) launched to the International Space Station to do just that — transfer and store cryogenic fuel in space for the first time.
