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...

The floor of the "young" ray crater on Rhea is really interesting.
http://ciclops.org/view.php?id=3713 Eastern part shows many small craters, but it seems that giant landslides completely covered the western floor where no craters are visible anymore. The ray crater seems indeed young and the landslides even younger. The landslides or "snow flows" remind me a little bit what is happening on Jupiter's moon Callisto. Both Rhea and Callisto are considered as the boring moons in their respective satellite system. I think it is really not the case. Marc. |

Rhea may look bland globally, but these close-ups are revealing an amazing amount of complexity at smaller scales. The sheer number of linear features is really remarkable, as UGordan observed. Beginning to wonder how many of the features that look like crater chains might actually be collapsed "cryolava tubes" dating back to Rhea's boisterious youth... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
