What a weird place! Hyperion is a lumpy chunk of ice only about 270 km (170 miles) across on average, but yesterday (August 25, 2011) Cassini passed about 25,000 km away from it, so it got a lot of high-resolution shots. <\/p>

As you can see, it’s saturated with craters. But they look funny! The overwhelming impression I get is that Hyperion is made of resilient foam, like a packing peanut. I’m also fascinated by the ginormous<\/em> crater that dominates this face of the moon. If Hyperion were made of stiff rock, an impact that size would’ve shattered it like a bullet hitting a pebble. But if the composition of the moon is able to compress and compact — like foam, or something with lots of pockets of empty space inside it — the impact would do pretty much what we see here. Lots of asteroids appear to be \"rubble piles\" — chunks of material held together by their own ...<\/p>
