NASA satellite will test orbital 'gas station' tech to help astronauts reach the moon and Mars

A new NASA satellite will test critical technologies for storing and transferring super-chilled, cryogenic fuels in space in order to help astronauts reach the moon and potentially Mars someday. The Liquid Oxygen Flight demonstration (LOXSAT) will launch to orbit around the Earth later this year to test the fluid management capabilities that will be needed to maintain cryogenic fuels in microgravity, which come with additional challenges compared to other propellants.
