What a remarkable story the National Geographic April 06, Cassini spacecraft picture of Hyperion tells.


As a miner, I see a classic out-bursting pattern on the face of this satellite with typical inverted cone structures showing all over the surface. Indeed a two stage event appears with a large outburst crater in filled with many smaller expulsion cavities. The inverted cones remind me of gas outbursts seen at some deep coal mines where pent up pressure escapes forcefully. It tells me Hyperion has come from a region of high pressure to one of low pressure. The nearest candidate for such an origin is Saturn itself.

Hyperion probably launched from Saturn before its gaseous contents were explosively liberated. The contents formed into icy rings visible from earth.

This places Saturn in the Projectile Dynamic Stage of planet development, equivalent to 3,400 Ma on Earth.
