Coolness! And good eyes, Explorer1. I noticed those too smile.gif Given that there's evidence for landsliding-type motion on other small worlds like Itokawa and Eros, I'd speculate wildly that's what we're looking at -- some kind of flow of the surface fluff toward local gravity lows, possibly induced by the vibration from small impacts.

Neat neat neat!

So when is the Mimas image down-link? This is the best view we'll get of Mimas for a long time to come, right? The suspense is just.... ugh! wacko.gif

I know; isn't it brilliant? Anticipation's half the fun! Every encounter is like a mini launch, orbit insertion or EDL smile.gif

(Obi Wan Kenobi voice on) Patience, young Explorer... impatience leads to anger, anger leads to hate, hate leads to... well, not a very nice place at all... (voice off)

Seriously, just enjoy it. We're spoiled rotten nowadays, and checking again and again to see if new images are up is all part of the excitement. smile.gif

Check out that darkening creeping up the crater walls! It's looks like sediment left over from liquid evaporation.

I don't think it's overexposed. More looks like the effect of very low phase on brightness and contrast. Also, who knows what the raw contrast stretch did here.

The last one is obviously Herschel. Very few craters on Herschel's floor and all of them are small. I expected to see some landslides on the crater rim's inside but there are none (or at least no big ones). One thing to keep in mind: The images are heavily contrast stretched because Mimas more than fills the field of view - no black space is visible. So I suspect that what's black in this image really isn't in black (in shadow).

There are some WA context images, for example this one:
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=213720

A nice NA global image:
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=213675

A closeup of Herschel with some black space visible - the contrast stretch doesn't mess things up completely in that case:
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=213654

Mimas' rough and uneven limb:
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=213606

Should be plenty of images for a nice stereo-derived DEM of Herschel smile.gif. The fact that the subsolar point is close to Herschel might be a problem though.

The image is heavily contrast stretched since no black space is visible so I think the darkening is only slightly darker than the stuff above it. Still very interesting.

EDIT: From the image someone said was overexposed I now see the contrast is higher than I expected (I'm looking at the images as I type wink.gif).
