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?

No, the equatorial ring must be some kind of accretion from the surrounding rings. No idea how that works yet, but Atlas also has an equatorial ridge, and soon we will get closer images of that to help us.
Galileo was supposed to be a Cassini-like mission for Jupiter, but its antenna problem resulted in less than 1% of the data return we could have expected. To be fair, it's a miracle we got anything from it at Jupiter. Phil -------------------- ... because the Solar System ain't gonna map itself.

Atlas also has an equatorial ridge, and soon we will get closer images of that to help us. Fingers crossed on this. The encounter with Atlas back in December 2015 at ~26,000km came close to missing Atlas due to uncertainties in its orbital perameters. This encounter I'm guessing will be a deal closer, with those uncertainties being magnified in the camera boresights. It will be a triumph if the team catch Atlas up-close. |
