Juliana Yu's essay about the rings of Saturn was one of 11 essays chosen out of 1,125 entries for the NASA’s Spring 2014 Cassini Scientist for a Day essay contest. In her winning and beautifully descriptive essay, Juliana wrote, “Saturn’s rings seem to swirl, twisting and turning in space. Streams of ice, dust, and debris form bands of moving rocks to create a halo-like arrangement around the planet. Its rings are Saturn’s best known feature, and its strangest, too.”
Contest participants in grades five to twelve chose one of three target areas for Cassini's camera: Saturn's F ring, Saturn’s moon Titan, or the north pole of the planet Saturn itself. The students wrote essays explaining why they thought their chosen picture would yield the most scientific rewards. A panel of Cassini scientists, mission planners and educators at NASA's Jet Propulsion Laboratory in Pasadena, California judged the essays. The winners and their classes were invited to participate in a videoconference to pose their questions about Saturn to Cassini scientists and engineers.
