How is fuel preserved in space?
Today’s Video of the Day from NASA describes the science behind fueling long trips in space.
Arthur Werkheiser is in charge of cryogenics at NASA’s Marshall Space Flight Center. He explained that cryogenics in space is a balance of resources, and that propellants must be kept cold to make the long journey into space and back.
According to Werkheiser, some of the other important factors in preserving the propellants are pressure, temperature, and insulation.
