The NASA Deep Space Network (DSN) is an international network of ground-based facilities that supports interplanetary spacecraft missions, as well as selected Earth-orbiting missions. It functions as a telecommunications system, commanding, tracking, and monitoring spacecraft, while also enabling scientific investigations through radio and radar astronomy. The DSN is operated by NASA's Jet Propulsion Laboratory (JPL) and consists of three strategically located facilities around the world, including in the United States (California), Spain (Madrid), and Australia (Canberra). NASA partners with organizations like the European Space Agency, the Japanese Space Agency, and the Indian Space Agency, and is also expanding through commercial partnerships to alleviate reliance on the DSN. Key products/services include deep space communication, data relay, and radio science observations.
