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.

JWST communicates with the Deep Space Network (DSN), downloading an average of 57 gigabytes of data per day.
The Orion mission obtained additional Deep Space Network time by negotiating with other missions using the DSN to shorten the 2022-12-03 outage.
A communications outage lasting four and a half hours on 2022-12-03 was caused by a hardware problem at the Deep Space Network center in Goldstone, California.
Some Chinese ground station assets in South America are part of the China Deep Space Network and supported lunar and interplanetary missions such as Chang'e-5 and Tianwen-1.
Testing with Peregrine and the Deep Space Network was conducted over two weeks and culminated in confirmation that Peregrine can successfully transmit data and receive commands through the Deep Space Network to Astrobotic’s Mission Control Center in Pittsburgh, Pennsylvania.
Morehead State University operates the newest affiliated node on NASA’s Deep Space Network providing telemetry, tracking, and control services for NASA and commercial deep space missions.
NASA’s Deep Space Network was designed over 30 years ago with very large 70-meter antennas to serve deep space customers.
The Microsoft Quantum team worked with the Jet Propulsion Laboratory to begin developing solutions for the Deep Space Network scheduling problem.
When Microsoft began working with the Jet Propulsion Laboratory, it sometimes took JPL more than two hours to produce a weekly Deep Space Network schedule.
Producing Deep Space Network schedules in minutes rather than hours allows JPL to create many candidate schedules and be more agile as missions and demands increase.
Frontier-S by Rocket Lab packs Deep Space Network and other common waveforms into a single board package using low power digital signal processing.
The Deep Space Network operates antenna sites in Australia, California, and Spain.
The stow process had originally been scheduled for early November 2020, requiring NASA to secure Deep Space Network (DSN) time from other users when it was moved earlier.
The stow process for the TAGSAM samples was planned to begin as soon as 2020-10-27 after finalizing procedures and securing time on the Deep Space Network.
Upgrades and updates to China’s deep space network facilities are underway to support the Tianwen-1 mission.
NASA’s Deep Space Network received a signal from New Horizons at 10:29 a.m. Eastern on 2019-01-01.
