• • Deep Space Network

    The NASA Deep Space Network, or DSN, is a global network of giant radio antennas that supports space missions. The DSN consists of three facilities spaced approximately 120 degrees apart around the world, in the U.S. (California), Spain, and Australia. This strategic placement permits constant observation of spacecraft as Earth rotates; and helps to make the DSN the largest and most sensitive scientific telecommunications system in the world. The DSN is managed and operated by NASA’s Jet Propulsion Laboratory (JPL).
