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

It depends whose "best" are referred to, I think. The set of images that are "best" by the criteria of scientific value[1] are unlikely to be a perfect union with the set of images are "best" at looking good at IMAX resolution.
[1] unquantifiable, anyway stephenv2 - there are surely high res colour images of sections of Titan's limb and atmospheric hazes. Depending on the extent you're willing to cheat (or extrapolate from such images) perhaps it'd be possible to generate a [partially] artificial image /based on/ the highest resolution image of the full disk, plus some carefully selected limb shots? -------------------- --

In order to do it, it would have to be one image in a potential mosaic to get enough of the limb to work with. Plus, It would end up a cheat as to my eye Titan is not perfectly uniform, fuzzy or not. It would end up being too much of cheat for my purposes anyway. But perhaps some images that could be used this way will still be taken. I will be working on film until at least late 2010, so there's still time. -------------------- stephen van vuuren

T-51 Titan ISS "Global Map" at 9 hours out? http://saturn.jpl.nasa.gov/files/20090327_...description.pdf It would seem they hope to have some cloud and haze features in there that would help mosaic-ing. |
