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.
