iss058e015157 (2/19/2019) --- Photo documentation of the Robotic Refueling Mission 3 (RRM3) hardware in the KIBO module aboard the International Space Station (ISS). Robotic Refueling Mission 3 (RRM3) demonstrates the first transfer and long term storage of liquid methane, a cryogenic fluid, in microgravity. The ability to replenish and store cryogenic fluids, which can function as a fuel or coolant, can help enable long duration journeys to destinations like the Moon and Mars.
