I work with cryognenic propellants.
Meet Arthur Werkheiser, Project Manager for Cryogenics at NASA’s Marshall Space Flight Center. Arthur works to safely store cryogenic propellant for spacecraft during travel. Through pressure and temperature management, as well as materials choices, he can keep propellants liquid to allow for the efficient use of fuel for long duration trips to Mars.
