My dad led the team at GE that built the RTG power plants that power the two Voyager spacecraft: the Multihundred-watt radioisotope thermoelectric generator (MHW RTG) is a type of US radioisotope thermoelectric generator (RTG) developed for the Voyager spacecraft, Voyager 1 and Voyager 2. The Voyager generators continue to function nearly 50 years into the mission.
Even worse than the Voyagers traveling without power, did you know that the sun will burn out before the California HSR project is finished and they will have to complete it in the dark?
LOL!
