How Long Will Voyager 1's Battery Last? NASA's RTG Power Explained
Discover how long Voyager 1's battery will last and how NASA manages its RTGs to extend its mission beyond 2025.

Voyager 1's battery is expected to last until around 2025. It relies on radioisotope thermoelectric generators (RTGs), which gradually produce less power over time. NASA engineers are carefully managing its power to prolong its mission and collect valuable data for as long as possible.
FAQs & Answers
- What type of battery does Voyager 1 use? Voyager 1 uses radioisotope thermoelectric generators (RTGs) which convert heat from radioactive decay into electricity.
- Why does Voyager 1's power decrease over time? The RTGs on Voyager 1 produce less power over time because the radioactive materials they use gradually decay, reducing the energy output.
- How is NASA managing Voyager 1's power supply? NASA engineers manage Voyager 1's power by turning off non-essential instruments and systems to extend its operational life as long as possible.
- Will Voyager 1 continue to send data after its battery fails? Once Voyager 1's RTGs can no longer provide sufficient power, it will stop transmitting data back to Earth, effectively ending its mission.
