Exploration & Space Communications
The Exploration and Space Communications (ESC) projects division at Goddard Space Flight Center in Greenbelt, Maryland, has reorganized its portfolio to execute the bold commercialization plan set forth by NASA’s Space Communications and Navigation (SCaN) program. This plan cements the U.S. government’s commitment to engage with private industry to build a commercial space economy.

This image shows the International Space Station together with the space shuttle, the vehicle that helped build the complex. The picture was the first taken of a shuttle docked to the station from the perspective of a Russian Soyuz spacecraft. On May 23, 2011, the Soyuz carried Russian cosmonaut Dmitry Kondratyev, NASA astronaut Cady Coleman, and European Space Agency astronaut Paolo Nespoli back to Earth. Once their vehicle was about 600 feet from the station, Mission Control Moscow, outside the Russian capital, commanded the orbiting laboratory to rotate 130 degrees. This move allowed Nespoli to capture digital photographs and high definition video of the space shuttle Endeavour docked to the station. Credit: NASA

NASA astronaut Kate Rubins points to the International Space Station's "voting booth" where she cast her vote from space last month. This is actually Rubins' second time to vote from low-Earth orbit, having cast her first vote from space in 2016 when she was an Expedition 48-49 crew member.

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.
