OK - for a little diversion, give your best guess as to the arrival of Oppy at Victoria. Before we do that, perhaps some agreement as when we can say that event has happened.
First complete panorama of crater interior perhaps? -------------------- My Open Office Website: http://www.openofficetips.com

A question about Victoria: from the orbital images it seems that there is a wide belt around the bright bedrock at the crater rim where there are no "etched terrain" light-colored protrusions. This area seems very smooth and young, with only a couple of tiny craters dotting it, and no relief that I can see other than some color variations.
Is this another field of sand? Does it show dunes or other relief at better resolution? If so, why does this region not show the "etched" bedrock? Or could could it be an area of smooth, exposed darker rock? or perhaps sand fused into something glassy as a result of the impact that created Victoria? |

To me it looks like an ejecta blanket (surrounds the crater, lobate shape). tty |

I've just been looking at the elevation profile from Ray Arvidson's MER MEX coordination slide (extracted in this post).
I appreciate that it is a very rough estimate based on MOLA data but by my calculations it puts the highest local point ("Hell of a view") within a band around Erebus so we should be heading "downslope" by now however I'm not noticing anything changing. I'm wondering if we're not actually going to see any noticable change at all and will never get that "Hell of a View" panorama. |
