Ice

I think the lighter stuff on the bottom of craters looks like cracked ice. About the "channels"- could'n that be originated through planetary movement? Just like the river-like gorges in glaciers on earth. :roll:

dark matter

At first I thought the so called dark matter was simply the shade, but looking closely at some of the bigger ones, it really seems to me as if there are black rocks at the bottom.

Re: Hyperion

[quote="sgjenks01"]My first impression was of a piece of pumice rock.

My thoughts exactly. I was thinking about the structure and my opinion is that indeed it looks very much like pumice rock.

Hyperion

This looks more like an asteroid than a moon to me. What I wonder about is why in the explanation is said that the picture is in false colour. There doesn't seem to be any colour at all, so I wonder how it would look like in "true colours".
