Nearly half a century after its 1977 launch, Voyager 1 is still operating far beyond the planets. In September 2026, NASA engineers replaced three heat-control devices with lower-power alternatives, a carefully coordinated change intended to stretch the probe’s dwindling energy reserves. The team also recovered communication after a brief interruption in October; NASA says the radio signal returned on October 20. The power-saving work should allow the remaining scientific instruments to stay active longer than expected. This GoodWorld report was independently written from NASA’s October 29 mission update.
A smart power-saving change could keep Voyager 1 exploring longer
NASA engineers have reduced the spacecraft’s electricity use, giving its remaining instruments more time to study interstellar space.
