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

Uh - 'they' have done lots of high resolution mosaics. But they are of the surface, not the hazy atmosphere, which would be a waste of time.

Uh - 'they' have done lots of high resolution mosaics. But they are of the surface, not the hazy atmosphere, which would be a waste of time. And I'm using them including using Mike Malaska's great work which gets me from visual to radar data. But that's actually precisely my problem. My script calls for me to approach Titan, go down through the atmosphere to the Huygens landing site - a very key part of my film. Unfortunately, today, it's not possible unless I do CGI which my film entirely based on only using real images. It's the only planet or moon in the film I don't have a suitable image of, ironically. I'm sorry you think it would be a waste of time. This is not really about my film but the value to world that a great high resolution photograph of Titan would have. I tend to think it may land on magazine covers, posters, newspapers and more. -------------------- stephen van vuuren

Unfortunately, today, it's not possible unless I do CGI which my film entirely based on only using real images. It's the only planet or moon in the film I don't have a suitable image of, ironically. Don't know if this will help but .... There's a web site that you should visit for images: http://photojournal.jpl.nasa.gov/index.html Click on planet Saturn then select Titan. Type in the following PIA numbers in the search box: PIA10008 this is a 185 meg of the north polar lakes PIA08391 this is a must shot of orange and blue titan atmosphere with Saturn ring in background PIA08117 this is the descent movie with bells and whistles that you might make into your journey throught the atmosphere to the Huygens landing site. While not very hi res there is no denying of the power of the gradual appearance of the alien landscape of Titan and rapid sequence to the surface with a view from the surface. PIA08112 Hi res fisheye color views of the Huygens landing site at different heights PIA06241 a movie of alien clouds moving over the visible south pole of Titan PIA02145 and 02146 infrared views of Titans topography including a mountain range and a blue cloud band I can imagine an approach showing Saturn and the orange Titan in full light and then a shot of Titan with sun behind it in eclipse; then a zoom in on PIA08391 to the descent movie to the surface. Go to the north polar hood shot PIA062366 then the infrared view PIA09171 of the giant north polar cloud then wow them with the higher res view of the north polar lakes PIA10008 that have formed under that giant cloud. |
