The Scientist for a Day contest challenges students to become NASA scientists studying three moons of Uranus: Ariel, Oberon and Titania.

In an essay of 300 words or less, participants will examine and research the three moons, and then write an essay about the moon where they think NASA should return. Participants must explain why they think the moon they choose would provide the best scientific results. Contest winners and their classmates will talk with NASA scientists.
