Wow, check out Epimetheus here. This just in!

The same grooves on an object about 5 x the radius of Phobos, and made of ice rather than rock... how bizarre.
New Mimas Saturnshine images are down as well! |

It looks that Epimetheus is another body in the Solar System with dune-like features on its surface (look at central lower part of this image).

People pondering the origin of the grooves of Phobos will need to think about this. Good point Phil - the two look visually analogous. I wonder if it's anything to do with these small bodies being at or near the Roche limit? The Mimas images are beautiful too - this phase angle really shows up the fact that Mimas is largely water ice rather than 'rock' |

Epimetheus really looks like two parts Phobos (the grooves and shape), one part Eros (the bicolored slopes).
It feels like we're getting close to something like a phase-state diagram of small bodies. Something like escape velocity on one axis and whatever else explains the varied nature of these places on the other axis/axes. It's remarkable how varied they are, but we're seeing repetitions of each phenomenon; the causes should start to become clearer. |

Amazing views.
Looks like there may be a few collapse pits in addition to craters. Reminds me a bit of a cometary surface, actually. -------------------- 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.

Some very nice images of Epimetheus recently. Here are two showing lots of grooves. I have brightened the area illuminated by Saturn to hint at what the raw data will show us when it arrives in PDS. one image is almost entirely lit by Saturn rather than the Sun.

Some great Mimas closeups in the newest raw images! Looking forward to colour composites from you excellent lot.
Here's a quick RGB composite from yours truly, with some cleaning up of the artifact, although it's still not perfect: That's no space station, it's one heavily cratered moon! -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

Incredible new views of Pan, and its razor-thin equatorial bulge!
North is to the upper-right. Staring face-on at the north pole. Edit: Thanks to Dr. Phil for pointing out my north/south confusion. -------------------- |

Another medium range view, bore-sighted on the moon's north pole:
