Design features proven here were carried into later, larger antennas. During its working life it tracked missions including Pioneer, Echo, Ranger, Lunar Orbiter, Surveyor, Apollo, Helios, Mariner, Viking and Voyager.","narrative":"Built in 1958 in the Mojave Desert at Fort Irwin, about 45 miles northwest of Barstow, this 26-meter steerable dish was the first deep space tracking station in NASA's Deep Space Network. The dish, made of punched aluminum panels on a steel framework, sits atop a 62-foot polar mount that follows objects from horizon to horizon. Construction began as an Army project under the Jet Propulsion Laboratory before NASA was created. The site was chosen for its natural bowl shape and distance from electrical and broadcast interference. The antenna served as the prototype for later stations, and it tracked missions such as Pioneer, Ranger, Surveyor, Apollo, Mariner, Viking and Voyager. Features developed here were later used in the 64-meter antennas that follow spacecraft to the edge of the solar system. It is now mothballed and technologically obsolete. NASA dedicated a plaque to the station in 1978. The nominated boundary covers only the antenna and its base.","period_of_significance":"1958-1978","architect_builder":"U.S. Army","architectural_style":null,"criteria":[],"status_note":"Mothballed and in standby status; technologically obsolete, with other NASA tracking stations now handling active space probes.
