So far images of Victoria - from orbit and from the ground, as Oppy approaches - have been tantalising at best, and frustrating at worst. What does everyone think we've seen so far, and what features do you think we'll see as Oppy approaches and later, when she finally arrives?

It's good to ask questions "outside the box", that fosters creative discussion. I think that the "rigid shell" idea may be applicable on smaller craters like Fram and those craters between Erdurance and Erebus where the top couple of meters of evaporite is broken and tossed about. No doubt we'll be seeing some of these little bumps on the way across the ejecta apron.

I notice that as we get closer to Victoria, the evaporate layer that we see in this pancam image is starting to take a ripple shape which is similar in size, shape and direction as the dunes. What do you think we are looking at here? Is this the edge of the ejecta blanket from Victoria that has been eroded by the wind or are the ripples formed from the impact itself and coincidently line up with the dune ripples.
