Today @NASA tweaked the power system on Voyager 2 so its instruments could stay online.
The spacecraft is powered by three MHW-RTG (Multi-Hundred-Watt Radioisotope-Thermoelectric-Generator) units.
They used Pu-238 to provide a total of 470 watts at launch, but Pu-238 has a half-life of 87.7 years, so 46 years later the craft is down to ~348 watts.
That they can keep a 50 year-old machine operating on a fraction of its power by making modifications from billions of miles away is AMAZING!
