In 2024, a critical concern emerged: Voyager 1’s roll thrusters—vital for orienting its antenna toward Earth—were showing signs of clogging, threatening the spacecraft’s ability to communicate. What followed was a technical drama that unfolded across billions of miles, culminating in an extraordinary feat of engineering in early 2025. NASA’s Jet Propulsion Laboratory (JPL) revived a set of thrusters that had been silent since 2004, defying expectations and breathing new life into a 47-year-old spacecraft.
