View from the Earth's north pole, showing the field of view of the main DSN antenna locations. Once a mission gets more than 30,000 km (19,000 mi) from Earth, it is always in view of at least one of the stations. Tracking vehicles in deep space is quite different from tracking missions in low Earth orbit (LEO). Deep space missions are visible ...

Originally constructed as a 64 m dish in 1973 and enlarged in 1987. It is the largest steerable parabolic antenna in the Southern Hemisphere. It is used by NASA to communicate with Voyager 2; the only antenna remaining on Earth capable to do so. [8] The antenna weighs more than 3000 tonnes and rotates on a film of oil approximately 0.17mm thick.
The beam waveguide antenna addresses these problems by locating the feed antenna in a "feed house" at the base of the antenna, instead of in front of the dish. The radio waves collected by the dish are focused into a beam and reflected by metal surfaces in a path through the supporting structure to the stationary feed antenna at the base.
The MDSCC is part of NASA's Deep Space Network run by the Jet Propulsion Laboratory. [3] The facility contributes to the Deep Space Network's mission to provide the vital two-way communications link that tracks and controls interplanetary spacecraft and receives the images and scientific information they collect.
