The In-Space Propulsion Facility (ISP) Vacuum Chamber at NASA’s Neil Armstrong Test Facility

NASA’s In-Space Propulsion Facility located at Neil Armstrong Test Facility in Sandusky Ohio is the world’s only high altitude test facility capable of full-scale rocket engine and launch vehicle system level tests. The facility supports mission profile thermal vacuum simulation and engine firing. The engine or vehicle can be exposed for indefinite periods to low ambient pressures, low-background temperatures, and dynamic solar heating, simulating the environment the hardware will encounter during orbital or interplanetary travel.
