Twenty-Five-Foot Space Simulator
United States historic place
About
The Twenty-Five-Foot Space Simulator is a chamber for testing spacecraft in space-like conditions, including extreme cold, high radiation, and near-vacuum pressure. Built in 1961, it is located at the Jet Propulsion Laboratory in Pasadena, California. It has been used to prepare many American space probes for their launches, including the Ranger, Surveyor, Mariner, and Voyager spacecraft.
The first facility of its type, the chamber served as an example for other countries seeking to establish space programs. It was declared a National Historic Landmark in 1985 and is on the National Register of Historic Places.
