The DSN also provides radar and radio astronomy observations. The DSN is operated by NASA's Jet Propulsion Laboratory (JPL). It consists of three facilities spaced equidistant from each other, approximately 120 degrees apart in longitude, around the world. These sites are at Goldstone, near Barstow, California; near Madrid, Spain; and near Canberra, Australia. The strategic placement of these sites permits constant communication with spacecraft as Earth rotates.
