Victoria's Wish List Options

Evidence of fairly recent laminar flow down the face of exposed sedimentary rocks.

A panorama, showing a rock, the trail it left, and the cliff it fell off of. I suppose it would be asking for too much for there to be an obvious spot for it to have fallen from.

[fredk]

A variation on Edward's theme: A vertical pancam panorama, a strip say 1x6, reaching up from cliff base to cliff top. Though I don't suppose you'd call it a "panorama" in that case.

I'd love a time lapse of a day at Vicky too, but I think I might prefer it from the outside, with Oppy set atop the Beacon. Perhaps a realistic project for a post-mobility (shudder shudder) rover.

I believe the word you were looking for was mosaic...

A vertical panorama? - in TV-speak here in the UK, the vertical version of a pan is a tilt. So I'm coining the word tiltorama! Though if the view was of a distinctive object - and with a nod to nprev - I rather like the idea of a "featurama".

An example of a tiltorama is attached...Giant Sequoia tree just doesn't fit in one frame.

I've used the free version of autostitch to do vertical pans, but it does REALLY WEIRD things if the images are upright. It's like it's looking for a horizon or something. I flip the frames 90 degrees on their side and it stitches them fine, then I flip the resulting pan vertical.

...evidence that would confirm recent water activity somewhere within Victoria (it's possible because of the pipes along the NE side of the crater). Perhaps a close up image of one of those pipes.

That's an awfully premature conclusion. A *lot* of things can cause relatively straight-looking linear formations (like the roughly linear formation along the NE rim). Just because someone, somewhere has *hypothesized* that other linear features in entirely different landforms that look something like what we see in Victoria *could* have been caused by water traversing along a joint in the rock doesn't automatically make these features in Victoria "pipes."

That and the *only* thing that has ever been seen and hypothesized as a sign of recent surface water movement are gullies on crater wall slopes, and there isn't even the first hint of such things here at Victoria.

So, the hypothesized ancient "pipes" (if that's what they are) seen elsewhere on Mars are not thought to be associated with recent water activity, and it's only a somewhat wild speculation that the linear features in Victoria have a similar origin to other supposed "pipes." And, of course, the only sign that anyone accepts as even potentially showing signs of recent water activites, gullies, aren't evident at Victoria at all. Anywhere.

Other than that, yeah, you've got a good suggestion there...

The word "Perhaps" as I used it indicates doubt. This is a wish list, afterall.

Edit: Also, pipes might explain the dark dust, if the deposits on the streaks come from a chemically altered source. Granted, there are plenty of other potentially good explanations; but I don't think we can eliminate this particular possibility yet.

Hey, MII -- I didn't mean to sound negative, there. And, I note, in the first 'graph of your post, you did say that both of the events you described are, indeed, unlikely in and of themselves.

My whole point, here, is to try and drag the reins back a little bit on the horse of unbridled speculation. The "pipes," as they have been called, that have been speculated upon elsewhere on Mars are considered to be extremely ancient remnants of water transportation along joints in rockbeds. The speculation is that these "channels" might have transported water several billion years ago. There is no connection whatsoever between that theory and any theory of any still-liquid underground aquifers on Mars. The gullies that have been observed seem to be explained best by ice deposition on crater walls, direct from the atmosphere, which is then protected and warmed for long enough to exist as liquid water very close to the surface. For a very short period of time.

What I wanted to take strong exception to is a statement like "We want to spend time and energy looking for recent water activity, which is made possible by the discovery of water transport pipes within the crater walls." As I have mentioned, that statement is simply not true -- there are no signs of recent water activity within Victoria, the "pipes" are likely to be nothing more than linear joints in the rockbeds that existed before the Victoria impact, and even if these joints did once transport water, that hasn't happened in a *long* time, probably billions of years.

Fair 'nuff?

A fossil.

How would be know it when we see it?

Evidence of fairly recent laminar flow down the face of exposed sedimentary rocks.

I'll bet that the dunes within Victoria are evidence of downward laminar flow. My reasoning is that as wind flows across the Meridiani plain and encounters the ejecta apron of Victoria an airfoil effect will occur, resulting in a vacuum within the crater which will draw air from near the surface of the ejecta apron and downward into the crater.
