I'm sure all here know the famous composite pia06193 of Saturn. However, creating an animation with this has been impossible thus far.
I've been looking for some time without success for the data behind the rings, especially the blue clouds and ring shadows - and of course need R/G/B/ exposures for color. The best I've found is PIA06142 and the raw sources but Cassini is still too "low" here and I don't see much more in PDS unless I'm missing something. Ideally, images from Cassini with the spacecraft "up higher" relative to the ring plane with the same sun/shadow config. I'm hoping this data exists otherwise I won't be able to do much with this at all. Any help much appreciated. -------------------- stephen van vuuren

Go to the imaging node, go to the atlas search
http://pds-imaging.jpl.nasa.gov/search/search.html Select "ISS" on the left and "SATURN" under the target. If I understand you correctly, you want the view to be above the ring plane so you need to select latitude from 0 to 90 under the Geometry tab. Not sure what you want for phase angle but you can limit that at the bottom of the QuickSearch tab. I tried a sample search on ISS, SATURN, latitude from 15 to 90, phase angle from 0 to 30 and got 279 images. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I will look through those. -------------------- stephen van vuuren

I'm not sure what result the latitude method gives as I don't have time to experiment, but isn't that just the bounding box of the frame? That still doesn't preclude Cassini from being under the ring plane, looking "up". An additional restriction by "Sub Spacecraft Latitude" in the Geometry tab should ensure you get northern hemisphere shots AND ones where the rings don't get in the way.

Hmmm, I was just noticing this. But I'm not sure I follow how values in the "Sub Space Latitude" work - is that the spacecraft's position relative or absolute to Saturn?

Sub-spacecraft point (i.e. Lat/Long) is the point on Saturn directly underneath the spacecraft. If you want to be north of the ring plane, this will have values from 0-90. If the spacecraft is almost at the ring plane, that value should stick close to 0. etc.

Thanks! That make perfect sense now.

Sorry, I did mean sub-spacecraft latitude. Thanks for clarifying, Gordan.
