Communicating in Space

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 large antennas on Earth.

The SCaN (Space Communications and Navigation) Program leads the agency’s space communications operations. SCaN’s networks and technology advancements enable more than 100 missions to explore the unknown, innovate for the benefit of humanity, and inspire the world through discovery.
