Voyager 2 RTG Efficiency and Facts

The video introduces radioisotope thermoelectric generators (RTGs), explaining their function, efficiency, and longevity. RTGs are used in space missions like Voyager and Curiosity due to their long-lasting power supply, despite their low efficiency. The video discusses the degradation of RTGs over time, with a 0.7% annual efficiency loss. It highlights the debate on whether the RTG or the wheels of the Mars rover will fail first. The video concludes with a call to action for viewers to engage with the content on social media.
