NASA selected 45 student essays as semifinalists of its 2024 Power to Explore Challenge, a national competition for K-12 students featuring the enabling power of radioisotopes. Contestants were challenged to explore how NASA has powered some of its most famous science missions and to dream up how their personal "superpower" would energize their success on their own radioisotope-powered science mission. The competition asked students to learn about Radioisotope Power Systems (RPS), "nuclear batteries" that NASA uses to explore the harshest, darkest, and dustiest parts of our solar system. RPS have enabled many spacecraft to conduct otherwise impossible missions in total darkness.
In 250 words or less, students wrote about a mission of their own that would use these space power systems and described their own power to achieve their mission goals. The challenges of space exploration without solar power are especially relevant ahead of the United States' upcoming April 8 total solar eclipse, which will offer a momentary glimpse into what life would be like without sunlight.
