(NASA's world-wide radio communication setup)

The NASA Deep Space Network (NASA DSN or DSN) is the unit within NASA that carries out radio communication with spacecraft, e.g., those at other planets. It operates large-dish transceivers (some 34m, a few 70m) at three locations. In addition to the communication function, which does not require all the equipment all the time, they are operated as radio telescopes and for radar astronomy. They also borrow the use of radio telescopes when they cannot meet their own equipment needs. Locations:
