When NASA engineers were looking for a place to build a network of large radio antennas in the 1950s, they knew they needed somewhere quiet.

They were going to build a series of antennas with huge parabolic dishes and receivers that could detect extremely faint radio signals.

They settled on a remote stretch of the Mojave Desert near the ghost town of Goldstone and the U.S. Army’s Fort Irwin–an area with no interference from power lines or commercial radio and television transmitters.

The first antenna built at the Goldstone Deep Space Communications Complex was the aptly named Pioneer Station. The 85-foot (26-meter) antenna began receiving data from the Pioneer 3 mission in 1958. The station was mothballed in 1981 after serving several high-profile NASA missions, including Apollo, Mariner, Viking and Voyager. It was declared a National Historic Monument in 1985.

The largest and most sensitive antenna at the Goldstone Complex is at Mars Station. It spans 230 feet, stands 24 stories tall, and weighs 16 million pounds. One of the satellites this antenna is used to communicate with is Voyager 1, a far-roving spacecraft launched in 1977. Voyager 1 is now more than 13 billion miles from Earth, making it the most distant human-made object in the universe.

Echo Station is the current administrative center for the complex. Built in 1959, the station was named for early experiments performed with the Echo 1 communications balloon. The metallic balloon, known as the world’s first communications satellite, ascended to 1,000 miles, and relayed radio and radar communications between an antenna at Echo Station and a receiving station in New Jersey.

In a departure from the traditional method of naming a station for the first mission supported, Gemini Station is named for the twin stars in the Gemini constellation. The antennas were originally built by the Jet Propulsion Laboratory for the Army and were transferred to NASA in 1994. The first mission Gemini supported was the Solar Heliospheric Observatory, a cooperative mission between NASA and the European Space Agency.

The Goldstone complex is just one of three facilities in NASA’s Deep Space Network. Similar stations exist in Madrid, Spain and near Canberra, Australia. The strategic placement of the three sites allows for constant communication with spacecraft as Earth rotates.
