The Dish in the Stanford foothills

The Dish is a radio telescope in the Stanford foothills. The 150-foot-diameter (46 m) dish was built in 1966 by the Stanford Research Institute. The cost to construct the telescope was $4.5 million, and was funded by the United States Air Force, with the original purpose of studying the chemical composition of the atmosphere.

Later on, the Dish was used to communicate with satellites and spacecraft. With its unique bistatic range radio communications, where the transmitter and receiver are separate units, the powerful radar antenna was well-suited for communicating with spacecraft in regions where conventional radio signals may be disrupted.

At one point, the Dish transmitted signals to each of the Voyager craft that NASA dispatched into the outer reaches of the solar system. It has also been used to remotely recalibrate ailing satellites orbiting the Earth.

The dish is still actively used today[1] for academic and research purposes.

Recreational trail[edit]

The area around the Dish offers a popular 3.5 mile recreational trail, visited by an average of 1,500–1,800 people daily.[2] The trail around the dish is known for its daunting hills and beautiful views, which on a clear day extend to San Jose, San Francisco, and the East Bay. While hikers, walkers, and runners are welcome, biking and dogs at the dish are not allowed. The opening hours are as per the schedule below, roughly matching 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

In 2011, 213 cows lived on the grounds of the Stanford Dish, according to Stanford's real estate office. Stanford leases the land to farmers who own the cows.

Mountain lions sightings[edit]

A sign at the entrance to the Stanford Dish encourages recreational users to keep an eye out for mountain lions. The area is a known habitat for the large cats, though sightings are extremely rare.

Most recently, the university issued a warning in January 2011 after mountain lions tracks were spotted outside the entrance to the Dish at the intersection of Junipero Serra Boulevard and Campus Drive West. Fresh tracks were seen on dirt trails leading to Lake Lagunita, on the campus side of Junipero Serra. The following instructions were given to trail visitors:

If you see a mountain lion, do not run and do not turn your back. Appear larger by waving your arms or a jacket or other objects above your head. Make loud sounds and yell. Grab a stick or rock. Keep young children close. Slowly move away while watching the animal. Attacks are very rare and most frequently the animal will go away.[3]

Stanford requested that any mountain lions sightings on the Dish or surrounding area be immediately reported to the university police using the U.S. bound telephone number: (650) 329-2413.
