Long-time lurker on this forum, I thought it was time I posted something.
I bow to no-one in my admiration for what the Voyagers achieved in their brief flybys, but the advantages of an orbital tour are plain to see....
Best Voyager images of each moon are on the left of each pair, best Cassini image to date on the right.
The moons are: top L-R Atlas, Prometheus, Pandora, Epimetheus
bottom L-R Janus, Telesto, Calypso and Phoebe

Someone got quite the shearing in a collision, it would seem. -------------------- "After having some business dealings with men, I am occasionally chagrined, and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853

It's not yet been decided if it will be targeted for some images, but here's hoping.....

In this montage, Telesto appears to be larger than Phoebe, and much larger than Pandora... -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

I'll amend and re-post at some stage. If I'm right, as of now, the only moon which Cassini hasn't imaged at better resolution than either of the Voyagers, is Helene - which should get a closeup later this year. Fantastic mission, all credit to those involved, and for the almost instant availability of images to the public. I've been looking forward to a return to Saturn since 1981 - can't wait for Iapetus in close-up and a polar view of the rings - hope the hydrazine holds out until well into 2010 for the extended mission!!

Not to scale, and the orientations are all over the place, but it shows the advantages of an orbital tour at Saturn. I would love to be able to undertake a similar exercise for the Uranian system in the next 30 years or so.....
