The various vacuum chambers at NASA Glenn Research Center are used to simulate the atmosphere-free vacuum of space, and how that affects various materials, constructions, and rocket propulsion. Vacuum Chamber 5 (VF-5) is one of dozens at the research center, each used for specific testing projects. The center is named for John Glenn, the senator and former astronaut who was the first American to orbit the Earth.
