The Spongy Moon

Cassini passed by SVII/Hyperion a couple of days ago at a distance of 1000 km and snapped the best pictures ever of the tumbling moon. It's a mess. Craters everywhere. Even on cliffs. But the surface must be pretty crumbly since many craters seem filled in, much like failed attempts at sand castles. There are lots more raw images at the raw images site. Just select Hyperion and browse away.

UPDATE: They've processed some of the data now and have released some new stuff both on SVII/Hyperion and SIII/Tethys. Don't miss the movie.
