CICLOPS' Rev 49 Looking Ahead page is up. Highlights include a fourth monthy Voyager-class encounter with Tethys with 500m resolution over Odysseus (finally!)
Detailed mosaics of Rhea's prominent ray crater and points west are on tap for Old Scabby's second closeup. This should be a really cool periapsis passage to tide us over until the 10th of September. -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...

I've been saying for many, many months that Rhea exhibits more crater chains than I've ever seen on any other body in the Solar System. It has led me to speculate, here in this very forum, as to whether these chains are controlled exogenically (i.e., actual impact crater chains) or endogenically (i.e., tectonic features/fractures).
Note that the feature you linked to has a very small accompanying feature to the right and below (as this image is oriented). That much smaller feature is parallel to the larger feature. To me, that argues for endogenic control of these features. I think that the rather large population of such chain features makes Rhea a lot more interesting than most everyone else here thinks. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
