With its second to last swing by Titan the curtain has now opened on Cassini's final act. What wonders will we see in the rings?

slumps ? i do not know
the ridge dose look to be extruded -- think of a "Cream Puff" with the top and bottom smooshed together but with gravity pulling the "cream" out |

This reminds me of something I've seen in New England, on occasions when it snows very heavily with almost no wind. Snow can pile up on thin solid bodies, like signs, twigs, and power lines, in thin, tall stacks, almost like a playing card standing on its edge. What's remarkable here is how absolutely close to zero the lateral forces must be. That also implies that the primary component of velocity is also quite modest.
It's useful to keep in mind that electric fields may play a role here, too. For most solar system objects, gravity and Newton's laws are the only factors worth considering, but with tiny particles, electric fields can have an important effect. There's some literature on electric fields and Saturn's rings, and these closeups of Pan are likely to stimulate more. |
