Cassini pictures spongy Hyperion
BBC NEWS | Science/Nature | Cassini pictures spongy Hyperion
Spongy Indeed! ... It appears to me, in examining the enlarged photo of Hyperion, that the whitish cliffs are in fact the walls of a Mega-Crator that spans over 70% of the width of Hyperion.
And that several hundred smaller craters have slowly subsided in a regolith collapse, into the hollow core of Hyperion.
There is one larger crater near the bottom of the photo that ... while it's walls remained intact and frozen ... it appears that it's bottom was ground away, and flattened by it's slide down the whitish cliff walls.
