We are talking to 11 spacecraft right now

From Voyager in interstellar space to the James Webb Space Telescope, three dish complexes on three continents keep NASA in touch with its spacecraft as Earth turns. This page checks NASA's public feed every 30 seconds.

Three ears around the world

Placed far apart around the globe so at least one complex can face a spacecraft as Earth turns.

The bar is logarithmic: each step is ten times the data rate. An empty bar means NASA reported no rate.

Uplink vs downlink

"Up + down" means the dish is sending commands and receiving data. "Downlink" means it is only listening.

Why Voyager's rate is so small

Its transmitter is weak and it is billions of kilometres away, so the signal arrives extremely faint. Slow data is the price of that distance.

Why three sites

Earth rotates. With complexes in California, Spain and Australia, a spacecraft that sets for one is usually rising for another.

Data: NASA/JPL DSN Now. Spacecraft codes we cannot match with certainty are shown exactly as NASA writes them. The displayed rate is the sum of active downlink rates for the dish. NASA does not endorse this site. Photo credits: NASA images.
