NASA's Big Bang power move buys Voyager 2 another year

NASA engineers have extended Voyager 2’s mission by reallocating power from nonessential systems to preserve the craft’s three remaining instruments, using a carefully balanced power-saving maneuver called the Big Bang. The reallocation should keep the instruments operating for at least another year despite shrinking RTG power. Voyager 2 is now about 13.2 billion miles from Earth, with communications taking roughly 20 hours one way, and NASA plans to apply a similar strategy to Voyager 1.

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.
