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 Jase

Yeah, those are good choices... nice to have similar viewing angles for a lot of them, it makes the comparison easier.

Is the moon in the upper left, Atlas, really that flat on one side?
Are we talking landing strip here? 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 |

I think Atlas IS relatively flat on one side - depending on viewing geometry, we'll get a chance to see on 12th June next year when Cassini passes by at 31,369km with a phase angle of 128 degrees. It's not yet been decided if it will be targeted for some images, but here's hoping.....

A nice montage... but your image of Prometheus from Cassini is actually Epimetheus.

Another way to put this would be to have them each to scale. In this montage, Telesto appears to be larger than Phoebe, and much larger than Pandora...

Damn! - I missed that - you're absolutely right. 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!! |

Time for an update of this montage, following some juicy flybys of late. 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.....

 You forgot Pan the inner most moon of Saturn   And Helene a trojan of Dione is also missing -------------------- "Thats no moon... IT'S A TRAP!"
