https://phys.org/news/2018-06-deep-space-hub.html > 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 70 meters (230 feet), stands 24 stories tall, and weighs 7.2 million kilograms (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 (21 billion kilometers) from Earth, making it the most distant human-made object in the universe.
