A vacuum chamber at NASA Glenn Research Center in Cleveland, Ohio, USA

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 centre, each used for specific testing projects. The centre is named after John Glenn, the senator and former astronaut who was the first American to orbit the Earth.
