I'm going for sol 740...
shall we set 30 m as a real drive distance? or the drive where they must store the arm in its cradle? is driving to the "cliff" of erebus (I forget what it is called

) considered a drive?
jb

I think "the" drive will have taken place as soon as we cross a drift. In other words, as soon as we finally get off the Olympia parking lot.

I think that Oppy is on the way to the Mogollon Rim and may be setting up for traveling. I've annotated Phil's Polar Pan with a likely (potential) route: red is how we came, blue is how we may go.

But I will keep my old proposal from end of November -- it should be "lost" somewhere on this thread -- i.e. due south.
Found it, here: http://www.unmannedspaceflight.com/index.p...indpost&p=28324

WRT what should be considered as "the" driving sol, imo it will be the first move with a stowed IDD not followed by another IDD campaign but by additional driving (restricted sols or not). I maintain by bet for sol 735 and also would say it'll be in the range of 5-15m.

Bill Harris

Feb 15 2006, 12:08 PM

That's right, Tesheiner, I remember that route discussion from long ago and agree with it. I _thought_ that is what I highlighted in blue, but evidently the memory gets creaky over time...

Updated and highlighed in green is the proper non-purgatory-esque route.

I'm giddy with the prospect of getting to the Mogollon homeplate in a couple of Sols...

We have seen that dark outcrop many many times since the IDD problems -- B&W, color, vertically exaggerated, etc. --, but it's the first time I can really see some layering there.

It's just me?

Bill Harris

Feb 15 2006, 03:22 PM

Nope, it's not your imagination. It is layered.

I've been trying to mentally decipher the morphology of the outcrop at Mogollon. In other words, _why_ is it there? I can see sand blowing off of the flat outcrop areas to give the Olympia outcrop, but what would make it blow out of a negative-relief area to give this "bluff"? This outcrop ought to be under drifting sand. Maybe it is an Anatolia on steroids?

Don't even think about Payson, yet. It seems to be odder still.

--Bill

Bob Shaw

Feb 15 2006, 04:29 PM

Is the dark outcrop raised above the mean level of the plain? Or is there a depression in front of it?

Bob Shaw

Feb 15 2006, 04:33 PM

I'd say that where the rover is now would equate to the same height as the top of the outcrop over on Mongollon rim - and that there is a depression between 'here' and 'there'. Essentially, we're looking across a crater to the far wall.

Actually that might be an optical illusion in that the ground continues to rise past Erebus and then drops towards Victoria. So you are seeing dunes bascially highlighted against the sky on this "hill". They are probably much nearer than they appear, and thus smaller.

I'm not a geologist, so I havnt a clue if this is right - but if you take an X-section of where we are now, to Mongollon Rim - I think it might look like this....

I think you've got the cross-section nailed. But I would put the "North Erebus Dunefield" on the left where you have Olympia (sic) shown and put Oppy's present location on the rim near where the Erebus Dune Field is indicated. There must be an aerodynamic (or maybe aereo-dynamic) reason why the sand does not collect at the bluff.

Has anybody heard or figured out the aims of Oppy's work since completing the festoon map at Overgard on sol 723? The work at Roosevelt and Rough Rider is looking at laminated rock, but not, as far as I can tell, at more festoon cross-bedding. Has this been a search that failed, or is there some other purpose I've missed?

Sunspot

Feb 18 2006, 09:54 AM

http://marsrovers.jpl.nasa.gov/gallery/pre.../20060217a.html

Some interesting info on "Roosevelt"

Roosevelt lines a fracture in the local pavement and scientists hypothesize that it is a fracture fill, formed by water that percolated through the fracture. This would mean the feature is younger than surrounding rocks and, therefore, might provide evidence of water that was present some time after the formation of Meridiani Planum sedimentary rocks.
