Deep Space Station 12 (DSS-12), the first deep space station, was built in 1960 to support the Echo program. This 26 meter (85 foot) hour-angle and declination (HA-Dec) antenna located in Goldstone, California, captured signals transmitted from a horn-reflector antenna in Holmdel, New Jersey that were reflected by a 100 foot diameter balloon orbiting the Earth. In the summer of 1962, the antenna was moved ten kilometers (six miles) to the southern edge of the Goldstone facility. In 1964, the antenna was decommissioned and converted into a radio telescope. The Goldstone Apple Valley Radio Telescope (GAVRT) is an educational program partnered with the Lewis Center for Educational Research (LCER) that allows K-12 students the unique opportunity to operate the telescope from a classroom.
