Without at least a 1/3 overlap I don't think a dust compensation flat field mask will work on the 8 bit JPG data.

I hope that the Cornell Pancam Images will have a dust correction.

It is however our first view taken from inside Victoria


... and this one might be the second. It's the navcam mosaic taken at the same position inside VC; same pointing but a bigger fov.

How can the entry surface of Duck Bay is so smooth, no boulders or stones? It seems that something has ironed it.

Endurance was as smooth as this, wasn'it?

The smoothness of the bays versus the boulder-strewn capes... not sure there is any consensus there!

Look for the discussions on "capes" and "bays" that are the terms used to describe Victoria Crater's scalloped appearance.

Yes, indeed, Endurance's lateral surface is similar to Victoria's bay (no Capes). This case puzzles me about these stones were laid down as smooth as possible.

The only idea that is arised in my mind: "When that place was so hot soon after an asteroid had impacted. It was like a magma and the left stones from the asteroid impact were able to accommodate to the Mars' gravity."

We discussed this issue, the apparently planed smoothness of the slopes irrespective of the irregular composition of mixed boulders and matrix, quite a while back and I can't yet find where. But the answer we came to was aeons of erosion by wind and wind-borne dust grains, slowly grinding the jumbled boulders and ejecta mass down into a plane surface. It was deposited lumpy and irregular by the impact, then slowly smoothed down over an enormous period of time.

An alternative hypothesis for Victoria is that the bays were long ago smoothed by wind abrasion, whereas the steeper capes are still shedding debris. Victoria may well be older than Endurance, most of which, except where Oppy entered, was relatively steep.

Edit: Ooops. Kenny, we both answered "wind" at the same time. Obviously, I was referring to post #36 above. Incidentally, one could equally well (probably better) argue that Endurance is older than Victoria, and the morphological differences mainly result from Endurance's smaller size.

Love the fractures that seem to run straight down into the crater. That one right in the center of your composite, especially. Post crater formation, yes?

What about the slope angle?
What I've got from the mobility data tells me the rover is on a (at least) 15º slope.
