What is powering the Voyager 1? It has been travelling in the space for almost 50 years.
In: Technology
If you’re referring to what’s powering the scientific equipment onboard: an RTG. It’s a radioisotope thermoelectric generator. Thermocouples convert heat into electrical energy and the heat comes from the decay of a chunk of radioactive material. Energy output gradually decreases over time as the material decays, so individual components are progressively shut down to reduce total system energy consumption.
If you’re referring to how it’s still travelling at immense speed, inertia and a practical lack of resistance due to the vacuum of space
