I did some renders and an animation of the E4 Enceladus flyby in March. The animation is available at http://www.mmedia.is/bjj/misc/css/stuff/e4...nceladus_e4.avi (warning: More than 5 megabytes). It starts on March 9, 2005 at 08:53 UTC and end 30 minutes later at 09:23 UTC. The distance from Enceladus at the start and end is roughly 6000 km and the field of view is 22.5 degrees. At closest approach Cassini will be roughly 500 km from Enceladus' surface.

I also did some renders from a greater distance:









Note that the field of view varies and is different from the animation.

[EDIT 22 February 2005: Updated the animation and renderings based on T3 images and added one rendering at the top]

You know that strange line between two terrain types that appeared in the Enc. image I put together a week or so ago - is that going to be visible more closely this time around?

I haven't checked yet (!) but here is what I think is the viewing geometry for images N00026543 and N00026567:





This may be a bit inaccurate though.

And now the nitpicking department: It would be nice to always indicate which images were used for making mosaics and color composites. Also I think the T3 thread I started before the topics were rearranged should be here instead of in Cassini General.

I have now updated the first message in this thread by replacing the animation and renderings with versions that include T3 data. Also I added one rendering.

The E4 flyby will be rather similar to the T3 flyby, the main difference being that this time the subspacecraft point will be south of the equator. Unfortunately the interesting-looking smooth (?) terrain to the east will not be in view near closest approach (the viewing geomtery for imaging it will be slightly better this time though).
