Stanford Dish (Stanford Radio Telescope)

The cost to construct the antenna was $4.5 million, funded by the United States Air Force. In the 1960s, the Dish was used to provide information on Soviet radar installations by detecting radio signals bounced off the moon. Subsequently, the Dish was used to communicate with satellites and spacecraft. At one point, the Dish transmitted signals to each of the Voyager craft that NASA dispatched into the outer reaches of the Solar System. In 1982 it was used to rescue the amateur radio satellite UoSAT-1.

As of 2018, the Dish is still actively used for academic and research purposes. It is owned by the U.S. Government and operated by SRI International. It is used for commanding and calibrating spacecraft and for radio astronomy measurements.

The area around the Dish offers a popular 3.5 mile recreational trail, visited by an average of 1,500–1,800 people daily. The trail around the dish is known for its rolling hills and beautiful views, which on a clear day extend to San Jose, San Francisco, and the East Bay. The Stanford Running Club hosts an annual Dish Race and fun run that forms a 3.25 mile loop around the Dish trail. While hikers, walkers, and runners are welcome, bicycles and dogs are not allowed on the trail. It is open during daylight hours: • Jan — Feb — Mar — Apr — May — Jun — Jul — Aug — Sep — Oct — Nov — Dec • opens (AM) — 6:30 — 6:30 — 6:00 — 6:00 — 6:00 — 6:00 — 6:00 — 6:00 — 6:30 — 6:30 — 6:30 — 6:30 • closes (PM) — 5:00 — 5:30 — 6:30 — 7:30 — 7:30 — 7:30 — 7:30 — 7:30 — 7:00 — 6:00 — 5:00 — 5:00 As of June 2018, 360 cows were grazing on the grounds of the Stanford Dish. Stanford leases the land to farmers who own the cows.
