Spacecraft Propulsion Research Facility

The Spacecraft Propulsion Research Facility, now known as the In-Space Propulsion Facility, is, the "world’s only facility capable of testing full-scale upper-stage launch vehicles and rocket engines under simulated high-altitude conditions." The facility, located at NASA's Neil A. Armstrong Test Facility of the Glenn Research Center near Sandusky, Ohio, was built in 1968. Its first major use was for testing stages of the Centaur Rocket, which was used to launch some of America's most important space probes. The facility was designated a National Historic Landmark in 1985.
