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?

Did somebody mention the dark streaks heading N from VC were (reletively) new features?
I have a hypothesis about their origin... Looking at the beautiful 3D view at http://www.msss.com/mars_images/moc/2006/01/24/ I can see a cliff between V2 and V3 descending into the crater. About halfway down the soil abruptly turns dark, perhaps newly exposed soil. The debris in the crater seems devoid of large rocks or boulders so the sides may not be more compressed clay-like soil that is prone to landslides. The dark plumes may be the resulting dust cloud released by a recent slide carried off to the north by the prevalent wind. A slightly older slide might the gully as mentioned before - the dark plume is not as dark having brightened because of sunlight exposure. I'm a longtime lurker and enthousiastic about this mission - so don't be too harsh in tearing this idea apart. ![]() |

Looking at the beautiful 3D view at http://www.msss.com/mars_images/moc/2006/01/24/ Whew! I'm not nearly as worried about the apparent steepness of Victoria's walls...if you look at the 3d image of Endurance it looks like a monsterous drop too, but we all know what it was really like. Check out the attachment of Victoria side by side with Endurance. -------------------- Eric P / MizarKey

Check out the attachment of Victoria side by side with Endurance. I must be getting pessimistic in my old age, because I just can't see any way into Victoria. The most "nearly" point must be just south of the prominent feature at around 4 o'clock, but even there the break in the upper 'crust' appears (to my ignorant eyes) to be perhaps half the entire depth of Endurance. Even if the sand 'ramp' is firm enough to support Oppy, and the angle is sufficiently shallow for Oppy to negotiate, how could she safely navigate the highest outcrop? I'd love to be proved wrong by events about this, as well as the arrival date... How thick IS that layer, anyway? It must be a couple of meters at the very least. Of course I'm speculating wildly... the resolution in those images must be a couple of meters at least, impossible to see how smooth or steep the slopes are at rover-scale. -------------------- --
