Which spacecraft is Earth talking to right now?
NASA’s giant antennas in California, Spain and Australia listen to dozens of spacecraft, from Voyager to James Webb. This page shows live which spacecraft each antenna is pointed at, the data rate and how far the signal has travelled.
…
As Earth turns, each station sees only part of the sky. Three complexes roughly 120° apart in longitude make sure a deep-space spacecraft is always visible from at least one. Each complex has one 70-metre dish and several 34-metre dishes.

How to read it
What you are looking at
↓ and ↑
↓ is data coming down from the spacecraft (science data, images, health telemetry); ↑ is commands going up from Earth. Rates are in bits per second: Voyager 1 sends a few hundred bit/s, while James Webb can send tens of megabits per second.
S, X, Ka and K bands
These are radio frequency bands. S band is around 2 GHz, X band 8 GHz and Ka band about 32 GHz. Higher frequencies carry more data but are more affected by weather.
Light time
The time the signal needs to travel from the spacecraft to our antenna. For Voyager 1 it is now about a day, so the reply to a command arrives almost two days later.
Voyager 2’s only listener
Because Voyager 2 is deep in the southern sky, the only antenna that can send it commands is the 70-metre DSS-43 in Australia. When that dish is under maintenance, Voyager 2 can only be listened to for months.
