How come it does not look like cracked ice?

I suppose it would be a gradually cooling = gradual cracking - not like jsut smashing an ice cube.

I know what you're saying though - they do look more like channels than cracks, but then I'm no planetary expert.

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:

Yeah.... - though that would suggest either cooling from the INSIDE out, or cryovolcanism.

As meteors impact; the cleaner ice underneath probably gets exposed. It looks almost more like packed snow.

How many "sling shot" type maneuvers would it take to finally get an object into a orbit like this one? :wink:
