I've not be able to find a good answer to this question. High resolution visible light images of all the major moons of Saturn seem to exist but I don't see anything much over 500 pixels and not very usuable. I desperately need one for my film. I realize that the hazy world may make it seems there is not much science value in this but I'm not 100% convinced of that. Plus, I suspect a really high resolution image (say a 16-image one) would be well worth the cost from a PR viewpoint and perhaps it would reveal some interesting info as well.
I have not found any real orbital/mission reason it could not be done before Cassini is finished. Anyone have any insight? -------------------- stephen van vuuren

The southern trailing hemisphere has been poorly covered to date by Cassini. There is no getting around that. We have a non-targeted encounter, IIRC, coming up later in the XM that will help fill that gap. We are trying to fill in coverage over the leading hemisphere now. But that is mostly over the southern hemisphere, so that corridor from TA/TB at 120 W does look a bit fuzzier.
60S up between 0 and 60W - do you mean 285-315W. 0-60W looks just fine to me. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

60S up between 0 and 60W - do you mean 285-315W. 0-60W looks just fine to me. Oops -- I said 60S and meant 60N! Look at the north polar region (lower-left in the link I posted). From the pole down to 60N , there's a missing wedge between 0 and 60 W. You can sort of see this in the rectangular map too. There's very little above 60N at all, of course, but from 0 to 90W or so, there's a lot missing between 60N and 30N. Of course, after the equinox you'll get some great north polar pics, right? And, uh, don't forget to wrap up the south polar ones before that! :-) --Greg |
