Power to Explore Student Challenge 

K-12 students, your task is to plan a mission that uses Radioisotope Power Systems (RPS) to a dark, dusty, or far away moon in our solar system.

Power to Explore Student Essay Challenge 2025

Did you know that our solar system boasts nearly 300 moons, many of which remain mysteries to us? These moons provide an incredible opportunity for discovery. Radioisotope Power Systems, a type of nuclear "battery," have powered missions near Jupiter's moon Io, where over 400 active volcanoes were revealed; Saturn's dusty moon Titan, where it helped uncover its methane lakes, oceans, and rivers; and Pluto's moon Charon, where NASA recently discovered jagged mountains and deep canyons.

The annual NASA writing challenge invites K-12th grade students in the United States to learn about Radioisotope Power Systems (RPS), a type of nuclear “battery” integral to many of NASA’s far-reaching space missions, and then dream up a totally new RPS-powered mission to any moon in our solar system.

If you could plan an RPS-powered mission to any moon in our solar system, which moon would you choose to unravel its mysteries?

NASA wants to know what you plan to explore, the discoveries you hope to make, and how you would use this special power to achieve mission success.

Your entry should address the topics below:

  • Dark, dusty, or distant mission destination: Tell us which moon your RPS-powered space mission will go and describe your mission goal(s). Keep in mind that your mission can either flyby, orbit, land, or rove. 
  • Radioisotope Power Systems (RPS): Explain the importance and advantages of using RPS for this mission. How does this technology overcome the challenges of these extreme environments and destinations?
  • Your power:  NASA missions are also powered by people – from mission planning and development, to designing, launching, and operating a spacecraft. Tell us what you think your unique power is and how your special power will help you achieve mission success. Your power could be a skill, personality trait, or other personal strength that is uniquely you.
