In January 1986, the mighty spacecraft reached the Uranus system. Voyager 2 took as many images as possible of anything within sight. Those were very brief visits, though, and we only know what one side of these faraway moons looks like.
Which of these three moons inspires you to explore further?
What excites you about what we’ve learned so far?
What do you hope we’ll find if we return to these places?
Support your choice in an essay of no more than 300 words.
The essays of winning students will be published on NASA's Radioisotope Power Systems website.
Good Luck!
