Apollo Valley, originally used in the Apollo missions to the Moon, is now home to the largest cluster of antennas at Goldstone. A 26-meter-diameter (85-foot) and three 34-meter (111-foot) antennas are in round-the-clock communication with spacecraft throughout the solar system, as well as ones relatively close to home as they orbit Earth.
The 34-meter antennas stand approximately 11 stories high and are the newest and most advanced at the facility. They are equipped with the sophisticated technology of a beam waveguide, which brings signals collected by the antenna to an underground room housing receivers and amplifiers.
Apollo Valley also has two decommissioned dishes: an 11-meter (36-foot) and a 9-meter-diameter (29-foot) antenna.
