Voyager 1 is expected to shut down around 2025 because its power source, the Radioisotope Thermoelectric Generators (RTGs), is running out of juice. These RTGs have been gradually losing power since the spacecraft was launched in 1977. As the power drops, Voyager will have to turn off its scientific instruments and other systems, eventually going silent after an amazing run.
