In the decades following the first spacefaring rockets, solar power and radioisotope thermoelectric generators have been responsible for providing power to probes, spacecraft, rovers, and more. In the process, these technologies have been fine-tuned and perfected to make them sturdier, more efficient, and more compact. While these advancements may not necessarily bring about a glorious future of space imperialism, they may contribute to a brighter, cleaner future here on Earth. Since the 70s, NASA has driven innovation in solar panel technology, including designing self-cleaning panels that can keep off dust and dirt. As greenhouse gases build up in our atmosphere…
