Seeking Stripes on Dione

 

The Cassini site has this nice June image of Dione from 374,000 miles posted today. On the lower part of the moon are the bright cliffs that the Voyager probes imaged in much less detail. Astronomers of the 80′s and 90′s thought they were seeing wispy tracings of frost or something.

What intrigues me more about this image are the broadly parallel ridges in the upper part of the moon as imaged. Do they remind you of this surface feature on another Saturnian moon?

Enceladus is less cratered, but similar, I think. My hunch is that those cliff faces on Dione and those ridges might not be as active as the plumes on Enceladus, but they might be worth exploring as vents from water below.
