Iapetus in color again

This is an attempt at a natural-color picture, from RGB filters:



There's just a slight brownish tint there. You can see the end of the mysterious equatorial mountain range coming in over the horizon on the left. It looks like it runs out not far from the edge of the biggest crater.

I don't know much about kids' sites, but for a 12-year-old who's interested in astronomy, I'd say that a lot of the "adult interested layperson" material would be appropriate and comprehensible. The Planetary Society (http://www.planetary.org/home/) just redesigned their site and there's a tremendous amount of good stuff there. NASA's Astronomy PIcture of the Day (http://antwrp.gsfc.nasa.gov/apod/astropix.html) is usually incredibly cool and the captions have links to associated material; it's a good place to start exploring. The Jet Propulsion Laboratory home page (http://www.jpl.nasa.gov/) is good for keeping up with planetary exploration, and the Cassini home page (http://saturn.jpl.nasa.gov/home/index.cfm) is frequently updated with interesting things.

Most of the government and nonprofit sites have "for kids" sections too, of varying quality.
