Space Power Facility
From Wikipedia, the free encyclopedia
The Space Power Facility (SPF) is a vacuum chamber built by NASA in 1969. It stands 122 feet high and 100 feet in diameter, enclosing a bullet-shaped space. When completed, it was the world's largest vacuum chamber. It was originally commissioned for nuclear-electric power studies under vacuum conditions, but was later decomissioned. Recently, it was recomissioned for use in testing spacecraft propulsion systems. Recent uses include testing the airbag landing systems for the Mars Pathfinder and the Mars Exploration Rovers, Spirit and Opportunity, under simulated Mars atmospheric conditions.
The SPF is located at Plum Brook Station, near Sandusky, Ohio. Plum Brook Station is part of the Glenn Research Center in Cleveland, Ohio.
