Hi Andrew. Since an axis shift would tend to re-align a high density region to the equator, could it be that the Tiger Stripe region is lower density than the rest of Enceladus? Hope all the close passes will provide a good global gravity map. Regards, Ray Gedaly
Looks like you have fracturing from tidal flexing, same as Europa. Am I remembering correctly that Enceladus is in orbital resonance with Dione? But wouldn't you expect to see more tidal effect at the equator than at a pole?
I zoom in further and see the small icy bolders with the sun casting huge shadows. I call them bolders but according to the scale they may be greater than 100 meters in size. Ray
Saw a better view of Skeet Shoot #3 and I'm beginning to get a better understanding of the scale. What I thought was a linear fault is actually the far wall of an ice block that is higher than the ice behind it. The near wall is in the foreground of the image. Are these the ice blocks described by the imaging team? I was initially looking for these ice blocks to be a few pixels in size; the details here are amazing!
Terrain in Skeet Shoot #3 has similarities to Europa with extensional faults and grabens. There appears to be a linear fault cutting across the center of the image. It appears to be younger than other features. Features such as the fracture or ridge appear to be offset on either side of this fault. Ray Gedaly
I'm sure I could find the answer if I researched enough, but my question is this: Has Enceladus' North Polar region been imaged sufficiently to rule out an impact basin or crater which could have focused enough energy on the opposite side of the moon to account for the fractures (tiger stripes) and volcanism.
