Chief Scientific Advisor's Briefing

Hello students,

I am Dr. Jeff Cuzzi, and once again I'm pleased to be participating in Cassini's "Scientist for a Day" program. I am the head scientist of Cassini's Rings Discipline Working Group, charged with leading Cassini's scientific study of Saturn's rings and its interactions with Saturn's environment. I work at NASA's Ames Research Center near San Jose, California, south of San Francisco, and have been studying Saturn's rings for more than 30 years.

I am happy to be recommending three potential targets from which to select your favorite. Each of these images provides an interesting and unique opportunity to learn more about the moons orbiting the ringed planet.

Cassini can take images with either the wide-angle camera or the narrow-angle camera. The narrow-angle camera focuses in on much smaller areas -- little postage stamps on the full wide-angle page -- but in return, we get much finer detail on those smaller areas.

We call the more detailed images "high resolution." The narrow angle camera would capture only about half of the area of the full moon, for example. We use both cameras for different purposes at different times.

Good luck with your essays, and I hope you continue to find Saturn - its moons and its rings -- as interesting as I do!

Dr. Jeff Cuzzi,
Chief scientist, Cassini rings discipline
