The real time status of communications with our deep space explorers

Welcome to "Deep Space Network Now"

At three sites around the globe NASA's Jet Propulsion Laboratory operates a network of large radio antennas called the DSN. The DSN is used to keep in contact with the spacecraft exploring our solar system and the universe beyond.

This online tool will let you see what the DSN is up to right now. Which antennas are currently in use? Which spacecraft are talking to us? How quickly is data being received? How long does a signal take to get there, and back?

The grid of antennas show you the current state of the network. 'Radio Waves' will show you if data is being sent to, or received from a spacecraft. Often both will be happening at the same time sometimes to more than one spacecraft at a time. Click on an antenna to see more technical information about the live link between the spacecraft and the ground.
