Keeping Explorers Connected

The Exploration and Space Communications (ESC) projects division recognizes that every moment is an opportunity for action. We stand ready to provide cross-cutting technical expertise and creative problem-solving to deliver not only high rate/full coverage communications services, but bold, forward-thinking solutions to advance exploration and discovery.

Our networks

The Space Network and the Near Earth Network, two vital pieces of space communications infrastructure managed by ESC, bring down 98 percent of the data from NASA spacecraft every day.


ESC engineers play a critical role in enabling NASA to explore more of our universe than ever before, crafting cutting-edge solutions for the next generation of science and discovery.


Exploration and Space Communications projects affect billions of lives around the globe, from creating technology for search and rescue to bringing down data used in weather forecasting and much more.

Expertise in…

Communicating is at the heart of every human endeavor, but it becomes especially important when communicating with humans and spacecraft hundreds to billions of miles off of Earth’s surface.

Our two networks combine to bring down the equivalent of 1,200 Blu-ray discs of data per day. That’s about 98 percent of the data from all NASA missions.

We provide communications support for more than 50 scientific, technology and human spaceflight missions.

We advance emerging technologies such as optical communications, quantum communications, disruption tolerant networking and more.
