Voyager 1 Nears Interstellar Space


35 years after it was launched Voyager 1 is still sending back data and we are able to receive its signal even though it is nearing interstellar space where the sun's heliosphere stops.

So where does Voyager get the electricity to send a signal back to Earth? Plutonium-238 nuclear power. The US stopped producing it in 1992. But this has been restarted to use in future space probes. -- FuturePundit:

Your Say

Restarting Plutonium-238?

Why? Did we run out of unicorn farts and rainbows?
