The Liquid Oxygen Flight demonstration (LOXSAT) will help NASA test and develop technologies to support in-space transfer and storage of cryogenic propellants, critical abilities for the Artemis program to return astronauts to the moon.
You can travel much farther with a full tank.
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.
