Pandora A shepherd of Saturn

The craters are so smooth that heat must have been applied at some point in time to melt some of the surface.

Would a gentle layering of some material not achieve the same effect? I'm think, if it's a shepherd, is it not possible that it's picked up some low density material from the ring?

I would go with the sand blasting and dust theory.

I'm new to this forum but it seems to me that if Pandora looks like it's covered in snow, and it's surrounded by snow (OK, ice-particles. etc. but close enough), then there is an obvious solution...

In short, I'm agreeing with The artist formerly known as... and S. Bilderback.

You are all correct, I'm sure. The evidence is there. I was looking for a comparison view of Prometheus [companion moon] but I could not find a good view. I wanted to see if there were comparable features. It should also have smooth features.
