The Deep Space Network (DSN) is a worldwide network of U.S. spacecraft communication facilities, operated by NASA’s Jet Propulsion Laboratory (JPL), that supports interplanetary spacecraft missions, as well as some Earth-orbiting missions. The network consists of three deep-space communications complexes positioned approximately 120 degrees apart around the world in Goldstone, California; Madrid, Spain; and Canberra, Australia. This strategic placement permits constant observation of spacecraft as the Earth rotates, ensuring that communication is maintained with any spacecraft beyond the Moon’s orbit.

The DSN’s large antennas and sensitive receiving systems are capable of detecting incredibly faint signals from distant spacecraft. Besides its primary role in communications, the DSN is also utilized for radar mapping of planets and asteroids, radio astronomy observations, and even some types of Earth-oriented research. The network’s capabilities are essential not only for the control of space missions but also for collecting science data and enabling deep space navigation, playing a crucial role in the success of missions exploring the solar system and beyond.
