Robotic Refueling Mission 3

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. 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.


Last week astronauts Anne McClain and David Saint-Jacques posed with RRM3 tools aboard the International Space Station before assembling them onto the RRM3 tool pedestal.


The space station’s robotic arm, Dextre, will soon transfer these assembled tools to outside Station, where they will be attached to the other, washing-machine-sized part of RRM3. Once the pieces are combined, the mission can begin demonstrating the transfer of cryogenic fuel—a capability that will help spacecraft live longer and humans journey deeper into space.
