The more fuel the rocket carries, the heavier the spacecraft. The heavier the spacecraft, the more fuel it requires to launch. Experts at NASA’s Glenn Research Center in Cleveland are testing technology that could solve this problem. The CryoFILL (Cryogenic Fluid In-Situ Liquefaction for Landers) project could transform the way NASA fuels future space exploration missions, reducing costs and extending the duration of planetary surface operations.…
