For how long will we still be able to communicate with the amazing Voyager 1?

Hi Lars Hansen.

If you click on the ≡ symbol at the top right of your screen you will find the PF SEARCH facility where a search on titles can discover discussions on the Voyagers. There is sure to be a recent discussion where you can learn much, and ask questions.

Good luck!

Suzanne Dodd, the Voyager project manager at NASA's Jet Propulsion Laboratory, says the Voyager spacecraft are powered by a couple of nuclear reactors sitting on the back of the probe, but they will soon run out of steam. "The nuclear power sources lose about 4 watts of power a year," she says. At this rate, Dodd says, Voyager should have enough power to communicate with Earth until 2022 or maybe 2025.

At it current distance, a round-trip message from Voyager I to Earth and back again takes a little more than 33 hours. And Voyager scientists are allotted only 6 to 8 hours per day on the Deep Space Network, meaning there may not be somebody listening when Voyager is talking
