NASA bets on a 'Big Bang' to stretch aging Voyager probes’ interstellar mission
NASA plans a risky “Big Bang” engineering move on Voyager 2 in May–June 2026 to swap which devices stay powered (turning off heater-related lines, turning on others) to save about 10 watts and extend the probes’ operations. If successful, Voyager 1 would undergo the same adjustment later that summer. With roughly 230 watts left for systems and a transmitter around 200 watts, the twin spacecraft—launched in 1977 and now in interstellar space (V1 since 2012, V2 since 2018)—could keep returning science into the 2030s, potentially reaching around 200 astronomical units, though power will keep dwindling and some instruments may be shut down.
