Reliable space communication and navigation systems are critical to every NASA mission. Spacecraft commands, never-before-seen images, and scientific data are sent and received daily by NASA’s giant antennas on Earth. From the Voyager mission exploring beyond our solar system, to astronauts onboard the International Space Station, space communications provide the crucial connection to our home planet.

Exploring the Farthest Points of Our Solar System

Keeping in touch, no matter the distance.

From robotic explorers venturing the rocky landscape of Mars, to the Voyager missions unveiling the secrets of interstellar space, to the first woman and first person of color landing on the Moon—NASA’s Deep Space Network provides communications, tracking, and radio science services to missions that explore the furthest points of our solar system. Consisting of three ground stations around the world, its sites are spaced equidistant from each other, ensuring one complex is always in view of faraway spacecraft. The global network also serves as a planetary radar and radio observatory for science measurements.
