Voyager 1 Gets a Lifeline: NASA Tests Power-Saving Swap on Dying Probe
TL;DR Summary
NASA is testing a ‘Big Bang’ style power-swap on Voyager 1 to extend its life by turning off several aging loads and swapping in lower-power components, following a successful upgrade on Voyager 2. Voyager 1 now has only two instruments left (magnetometer and plasma wave) and sits farther away than Voyager 2, about 25 billion km vs. 21 billion km. If the thermal test is successful, the change could free enough power to potentially re-enable the Low-energy Charged Particles instrument; however, the plan remains cautious since commands take roughly a day to reach Earth and back.
