Your blog is always a pleasant reading, Stu, and I believe we are all eager to start moving again. Incidentally, I'm already working on the JPEG route map covering this final leg (see below a half scale version).

It's going to be a pretty flat ride!

And an overall downward slope the rest of the way can't be bad for those poor, sore wheels!

ET, thanks in advance for your ongoing efforts! Another innocent question: in your image, are the lighter-shaded areas rocky?

Hardly a slope. 1:160 means effectively dead flat. The visual representation of these graphs with such different axis metrics can be misleading. But the MOLA passes are pretty far apart here so there could well be swales, bumps and hollows to be found. But overall it does look life the sediments did a real good levelling job on the terrain.

Remember - Petes chart is from a HiRISE derived DTM - probably three orders of magnitude better than any MOLA gridded product.

I´m just curious - is it possible for Oppy to drive on top of Cape York ? The view around must be stunning !

Check out this post and those that follow for a discussion of this.

Short answer: Quite possibly.

Long answer: With an interesting "crack" at the North end, interesting ejecta blocks at the South end, and possible interesting erosion features all along the juncture between Cape York and the Meridiani pavement, who knows how long it will be before the urge to bypass all that and climb to the top will take hold. On the other hand, Cape York may turn out to be an easier traverse for Opportunity than Home Plate was for Spirit. Maybe a quick jog to the top before heading to the North or South end could be in store. Maybe head one way along the edge -- to the North for example -- then head the other way along the top. Or vise versa.

The scope of Cape York is kinda amazing to consider. This place is big -- like, Texas big!

Well... Victoria Crater big, anyway. smile.gif

So to examine Cape York as thoroughly as the perimeter of Victoria was examined could take a year.

I couldn't imagine them spending anything like a year at CY when the real goal of clays would be farther to the south (not that you meant to suggest that, 'worth).

In fact, I wonder if they may decide to head straight for Tribulation, where the biggest exposure of clays seems to be, instead of CY. Or perhaps straight to Solander Point instead and then south to Tribulation. CY is quite a bit out of the way.

And after we've gotten so worked up over how to study Cape York! laugh.gif

But finding clays before MSR is a stated objective. (How official, I don't know.)
Of course, Tesheiner will have to redo his "final Leg" route map.

Yes, but the sequences planned for 2543 make me wonder if this is just a small bump before taking the second part of the LBS mosaic.

straight for Tribulation


I agree. This must be gathering votes amongst those who will decide. In addition to the clays Tribulation has the same curious skirting shelf as Cape York so I can't see any obvious science that would be lost by missing out the latter except in the case that the rover fails just before reaching the slightly more distant target.
