But it was also mentioned that they wouldn't go up to the sides of the capes because of the shadowing (sun and telecoms) they would cause.

Ah, I'm sure the intrepid rover team will manage to find the right constellation of sun and communication angles to drive up and put the instruments on a cliff face. We should use the rover to its limits down there.

QUOTE (dvandorn @ Sep 15 2007, 10:07 PM)  Oppy's exact preplanned path, was that she would head down to the "bright ring" layer (otherwise referred to as the "bathtub ring") and follow it around, parallel to the crater rim, I have no problem with such a plan, but I would hope that the first thing they do is descend as far down the sequences as they can, ratting and sampling as many layers, as low as possible THEN go ahead and investigate along the ancient disconformity. The dust storms reminded us that every day could be the last one for either rover, and I can't imagine anything more important geologically than a full understanding of the layering sequence as low as we can possibly go. -------------------- If Occam had heard my theory, things would be very different now.

As far as I can tell, the most we know about where Opportunity will go and what she will investigate comes from this Aviation Week article. They point out that, after the toe dip...
QUOTE The plan is for the rover, heading south, to then drive 100 ft. into the crater. This will take several days. It will then be commanded tens of meters parallel along the crater wall. The objective will be to reach about a 1-meter-thick white rock layer that cuts through the wall of the entire crater--but at a point where it's easily sampled, not where it's also visible in the high promontories. I can't see how they can travel parallel to the light band of rock for tens of meters unless Opportunity turns to the south to follow it across the bay.I think the article also makes clear the initial scientific objective. QUOTE With Victoria, "we will really be making the first good vertical slice through an impact ejecta blanket and crater walls on another planet," says Squyres. Then they go on to say...QUOTE This is the original Martian surface layer before the meteorite hit, burying and preserving the layer that was originally directly exposed to the Martian environment. At a minimum, the area is expected to provide direct data on the Martian climate billions of years ago. And even more, it could be (the) "bathtub ring," showing the Martin surface or ground water level at the time. If it's a surface or ground water signature, it will be important to Martian life assessments.

Thanks a lot for the entry location map, Alan. If anyone would like to visualize Oppy on the slope, Astro0's SFX image in this post shows the rover in almost exactly it's current location.

Here are a couple similar MMB views based on the drive data. The rover position is slightly off, but the scale should be more or less accurate. Astro0 had it pretty much right.

Still on the issue of "which will be the next move?" I did a manual stitch of the "drive direction" mosaic from sol 1293 using the little thumbnails available at the pancam web. As this mosaic is usually used to plan the next move(s) it might give us a glimpse of the planned path.
This image correlates with the features in the *rightmost* picture of the navcam mosaic taken on the same sol, meaning that the plan (at least when these images were taken) is to move right (southeast), not left as I thought before. |

No new images from The Exploratorium web site since Friday. Is it down or did they take the weekend off???
Hopefully today we will get updated images

Are power levels still too low to permit direct transmission of images to Earth?

They could probably do short DTE sessions, but is it really worth it for the big power they consume and the DSN demand it would have? Better to have a few sit-tight days, full batteries, then on with the fun.

Here's another little experimental movie of the plunge
