The annual NASA writing challenge invites K12th grade students in the United States to learn about Radioisotope Power Systems (RPS), a type of nuclear “battery” integral to many of NASA’s farreaching space missions, and then dream up a totally new RPSpowered mission for the agency.

Entries are judged in three gradelevel categories: K4, 58, and 912. Student entries are limited to 250 words and should address the mission destination, mission goals, and also describe one of the student’s unique powers that will help the mission.
