Twenty-Five-Foot Space Simulator

The Twenty-Five-Foot Space Simulator is an 85-foot (26 m) high stainless-steel cylinder at the Jet Propulsion Laboratory in Pasadena, California that is 27 feet (8.2 m) in diameter.

It was declared a National Historic Landmark in 1985, and is on the National Register of Historic Places.

It is used for testing spacecraft in space-like conditions of extreme cold, near-vacuum pressure, and high radiation. Ranger, Surveyor, Mariner, and Voyager spacecraft were all tested in this facility.

Famous quotes containing the word space:

    Thus all our dignity lies in thought. Through it we must raise ourselves, and not through space or time, which we cannot fill. Let us endeavor, then, to think well: this is the mainspring of morality.
    Blaise Pascal (1623–1662)
