Exploring the Rings Options

[Bill Harris]

This might be a way for an orbiter to move closer to the ring plane without crossing the ring plane:

"The late Dr Forward -- a renowned physicist who worked in the United States and from his second home in Scotland -- believed it was possible to use 'displaced orbits' to deploy more satellites to the north or south of the Earth's equator, helping to meet the growing demand for communications."

Apologies for resurrecting an old topic (and probably posting on a tangent to boot), but I just had a thought.

Has Cassini done any extended nightside obs of Saturn's equatorial region? Reason I ask is that I would expect that at least some small fraction of the ring material eventually impacts the planet, and therefore there might be observable meteors. Constraining that infall rate would seem to be a significant data point for understanding the rings evolution & longevity. Might even help to derive a size distribution for the larger (<10cm?) ring particles.

I don't know if this is even possible to do given the enormous amount of backlighting in the Saturn system from the rings, and you'd probably have to do it when Cassini wasn't in an equatorial orbit. Still, I'm curious.
