Enabling missions within one million miles of Earth.

Astronauts onboard the International Space Station, missions monitoring Earth, and spacecraft exploring the Moon and beyond depend on NASA’s Near Space Network for communications and navigation services. Using a blend of government and commercial assets, the network supports science and exploration missions bringing back terabytes of critical data each day. 

Keeping in touch, no matter the distance.

The Deep Space Network (DSN) is NASA’s international array of giant radio communications antennas (with dish diameters of 34- and 70-meters) located at Goldstone, near Barstow, California, Madrid, Spain, and Canberra, Australia. The DSN supports spacecraft communication and navigation at the Moon, Mars and beyond, and its planetary radar and radio astronomy help scientists better understand the nature of our solar system and universe. 

SCaN is supporting a new era of lunar exploration.

SCaN contributes to NASA’s exploration of the Moon, Mars, and beyond. The program’s lunar activities encompass communications and navigation support to the Artemis missions, bringing internet-like capabilities to the Moon, and providing astronauts with robust search and rescue capabilities.

We’re adopting safe, reliable, and cost-effective commercial services.

SCaN is transforming its near space communications services and engaging the commercial industry for both direct-to-Earth and space relay communications services. Through public-private partnerships, SCaN is embracing new opportunities and building a safe, interoperable communications ecosystem.
