First frames are down. A very rough, 4-frame clear filter NAC mosaic from 25-ish thousand km away:
... and I take it these are the stars of Orion's Belt:

Wow, check out this crack-like feature: http://saturn.jpl.nasa.gov/photos/raw/rawimagedetails/index.cfm?imageID=246215
Is that the "Isbanir Fossa" feature on the Enceladus map? Looks really conspicuous in this geometry and lighting angle.
Edit: here it is, rotated so north is roughly up and contrast-enhanced:
Oh, great. Someone broke Enceladus...
Interesting. Two older cracks or grooves at right angles to that dark line appear to have beeen dislocated by the same big horizontal shear along it. However I can't see any 'sheared' craters, though some craters overprint the old grooves. I conclude that this crack has been active in two separate episodes. There was shear(strike) displacement along it at an early epoch after which it became quiescent while most of the craters formed. Recently the 'old line of weakness' has become active again, this time creating a small vertical step in the topography highlighted in this image.
Isbanir Fossa has been quite well imaged 30 years ago by Voyager 2:

Anyway, it's nice to have this amazing new perspective of this region of Enceladus by Cassini !

A little bit of reconstruction along the fault... make of it what you will...
