Messages from Juno and other spacecraft in the far reaches of the solar system are relayed to scientists via NASA’s Deep Space Network (DSN), which was created in 1958. DSN consists of three sets of powerful radio antennae spaced about 120 degrees longitude apart around the world near Barstow, Calif., Canberra, Australia, and Madrid, Spain. The complexes are all situated in bowl-shaped terrain in semi-mountainous rural areas to minimize interference from external radio waves. As Earth rotates, at least one of the DSN antennae is pointed toward the spacecraft at all times. Communications via DSN begin and end at NASA’s Jet Propulsion Laboratory, which manages the system.
