Just 8 days until the next Enceladus encounter.

CICLOPS Rev 80 Looking Ahead will appear here soon.

Cassini Enceladus 080EN Mission Description is here now.

We get to fly through the south polar jets again.

Here's some more good stuff on the WAC part of the closest-approach imaging, from Anne Verbiscer, who wrote the looking ahead feature on the ciclops site:
QUOTE
The WAC terminator image has a few purposes: it's still a pretty high resolution... 48 meters/pixel (in the WAC!); it will catch some portion of the sunlit side of the terminator.... and will contain the first sunlit pixels after closest approach. Truth be told, there is actually a BOTSIM *before* this WAC, totally in the dark... who knows what will show up in that.... I didn't talk about it in the writeup because it's too difficult to explain. Basically, it's done to set up the other footprints' timing. It's literally a "shot in the dark"...

So there's a wide-angle shot over the limb while no sunlit terrain is visible? If any image shows the plumes, it will be that one! I can't wait!

Sorry, ugordan, it's a WAC over the terminator, not limb. After ring-plane-crossing in 2009, the plumes will still be sunlit while the surface will be in darkness, providing just the opportunity you describe for ideal plume imaging.
