Goldstone Deep Space Tracking Center, California

Goldstone is the largest tracking station in the Deep Space Network, which is composed of three installations located at roughly 120-degree intervals around the globe (with one at Madrid, Spain, and another at Canberra, Australia) for a continuous view of space. Part of NASA's Jet Propulsion Lab, it is used primarily to communicate with deep space probes and satellites, and to study asteroids, among other astronomical phenomena. Facilities at Goldstone are clustered at nine separate complexes, spread out over 33,000 acres. Antennas used include eight 34-meter radio dishes and a 70-meter steerable dish.
