NASA willturn control of the Cassini spacecraft at Saturn over to students for a day ina contest aimed at boosting interest in science among today?s youth.

An essaycontest for students in grades 5 through 12 will determine which of threescience targets Cassini will photograph on June 10, the space agency announcedlate Thursday. Cassini scientists regularly debate exactly which images of Saturn?smany moons and rings will produce the most science results, a task they areturning over to elementary and high school students for the ?Cassini Scientist-for-a-Day?competition, NASA officials said.

"It's a really fun wayfor kids to learn about Saturn and what the mission is doing," said RachelZimmerman-Brachman, an education and public outreach specialist with NASA's JetPropulsion Laboratory (JPL) in Pasadena, Calif., in a statement. "Students haveto do their own research to write their essay. That way, they learn how to askquestions about the solar system and what we still need to understand.

On June 10, Cassini will beabout 493,000 miles (793,000 km) away from Saturn and zooming toward the planetat about 13,400 mph (22,565 kph).

That gives the spacecraftabout 55 minutes to turn its camera eyes toward any target, though the Cassiniscience team narrowed the list of candidates to the Saturnian moons of Rhea,Enceladus and a section of the planet?s rings that contains the planet?s tinysatellite Pan.

In order to select a target,students must write a 500-word essay on exactly what image they want Cassini totake and discuss its scientific importance.

Cassini recently flew pastthe moon Enceladus, an icy satellite that spewsplumes of water ice from fissures at its south pole. Rhea is Saturn?ssecond largest moon and may sport its own rings justlike its planetary parent, Cassini researchers have said.

Pan is a tiny moon, about12 miles (20 km) from pole to pole, and orbits Saturn inside a gap in theplanet?s trademark rings. Past Cassini studies have shownlarge bulges along the small satellite?s equator.

A panel of Cassini missionscientists, planners and JPL education officials will judge the entries andselect three winners; one each from elementary, middle and high school agegroups.
