Twenty-Five-Foot Space Simulator
Twenty-Five-Foot Space Simulator, Space simulation facility at Jet Propulsion Laboratory in Pasadena, United States.
The Twenty-Five-Foot Space Simulator features a stainless steel cylinder measuring 27 feet in diameter and 85 feet in height with aluminum cryogenic shrouds throughout.
Constructed in 1961 at JPL, this facility earned National Historic Landmark status in 1985 for its contributions to spacecraft testing during the early space age.
The facility represents a milestone in American space exploration, having tested numerous spacecraft including Ranger, Surveyor, Mariner, and Voyager missions before their launches.
The chamber requires 75 minutes to achieve space conditions and maintains temperatures from -320°F to 200°F while operating at a minimum pressure of 5x10-7 torr.
The simulator contains 37 xenon arc lamps generating an 18.5-foot-diameter solar beam that can produce intensities up to 2.7 solar constants.
