NASA Deep Space Network (DSN)

The NASA Deep Space Network - or DSN - is an international network of antennas that support interplanetary spacecraft missions and radio and radar astronomy observations for the exploration of the solar system and the universe. Learn more >>

NASA's Mars 2020 mission would rely on NASA's Deep Space Network (DSN), an international network of antennas that provide the communication links between the scientists and engineers on Earth to the missions in space and on Mars.

The DSN consists of three deep-space communications facilities placed approximately 120 degrees apart around the world: at Goldstone, in California's Mojave Desert; near Madrid, Spain; and near Canberra, Australia. This strategic placement permits constant observation of spacecraft as the Earth rotates on its own axis.

As with previous Mars landers and rovers, the Mars 2020 mission would also rely on Mars-orbiting spacecraft to relay data from the rover to the DSN Antennas.
