Go read Paul "DrShank" Schenk's blog (or his most recent papers on colors of Saturn's satellites) for the answer to this question!

Bombardment by high-energy particles? And on Mimas too....

In the past, I figured that these color variations were caused by lighter E-ring material from Enceladus drifting outward and darker material from Phoebe spiraling in.

5-frame mosaic of images taken along Enceladus' terminator through clear filters:

Very nice mosaic Juramike - looks like it could add some detail around the half-crater in this map:

http://laps.noaa.gov/albers/sos/sos.html#ENCELADUS

The crater in question is right near the left edge, just below the center. Reminds me of another half (cup shaped) crater near the bottom - and right edge.

That is the most aesthetically pleasing image of Hyperion I've seen yet.

It looks like Vesta from the 1970s before being reupholstered. smile.gif

Pretty awesome, isn't it? I badly want to color-compose even a still from the last sequence with Titan, Dione, Pandora, and Pan (did you notice Pan zipping around the corner?) but I'm afraid it's beyond my skill.

Pandora, and Pan (did you notice Pan zipping around the corner?)

Is that what those two are? I just noticed there is a 4th moon visible to the right and up of Titan: http://saturn.jpl.nasa.gov/multimedia/imag...0/N00175978.jpg

One of the trojans?

I didn't notice that one! And it doesn't seem to show up in the Saturn Viewer either, at least not at the same scale:

But if I widen the view to the WAC FOV, you can see Methone. I wonder if it could be Methone, not quite showing up in the spot it was predicted to? Jason??

A random interjection: here's a nice little shot from the Hyperion encounter:
