This is the best Cassini image of Enceladus so far:
http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=26006 Some relief is visible along the terminator, including what looks like positive relief near top. The distance from Enceladus is 765,000 km. The subspacecraft point seems to be at roughly lat=5, lon=270. This would put this feature at roughly lat=41, lon=120. Bjorn |

I'm attaching two processed Voyager images showing this feature, assuming the location I mentioned above is correct (which is likely but not certain).
Doesn't look too special, there are a few craters there and (perhaps more interestingly) some dark material. Bjorn

isn't the 'darl material' just shadow from what appears (from Cassini) to be an elevated feature?

This feature doesn't look like a shadow in lower resolution Voyager images where it is farther from the terminator and looks like a darkening.

I wonder if Cassini will see any changes to Encelaus since the Voyager Flybys.
