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

I am kind of curious why we don't seem to have better resolution maps of Titan by now, though. It seems (naively, perhaps) that there have been quite a few different flyby traectories by now, so I'd have expected most of the super fuzzy regions to be filled in. Or am I just not looking at the right composite?
http://photojournal.jpl.nasa.gov/jpeg/PIA11146.jpg For example, there's a big blurry spot at 30S, 270W. And a fuzzy corridor at 120W between 0 and 30N. On the South Polar map, there's a completely blank spot at 60S, 300W. I can understand that the North has been harder to image, pending the Equinox, but why is there a blank WEDGE from 60S up between 0 and 60W? If only to help planning for future missions, I'd think we'd want 100% coverage of the surface to some resolution. --Greg |
