Images post sol 2678 drive down. Navcams look beautiful!

There are a bunch of Hazcams as well related to a technology demonstration.

About 70m further tosol (2678) - should have a great view of Spirit point now! smile.gif

That's interesting. There was some mention recently of attempting to warm the rover's electronics to try to mitigate clock drift. Is it possible to just reset the clock to correct for the drift?

Yes and no. That's an extraordinarily complex issue, not least because we have to ask the question, "What clock?" and the question, "Relative to what?"

We have several ways of mitigating the drift, none of which are trivial. There's no real *reset* button to do it. (And for good reason.)

We have seen less drift of this particular clock when the rover is warmer. The theory is well supported by the data, but we have yet to implement the fix in tactical activities. It's low on our radar.

I'll stop talking before I get in over my head.

So what is this and how did it form?

It this a little dust-filled deflation hollow? Have we seen things like this before?

I personally love the deflation hollow theory of the little depressions we have been seeing, and i think this is one of them. The bedrock void creating it could be enhanced by the fact we are so close to the rim of endeavour.

It's not on the exploratorium servers yet, but Matt's got a fine shot of Odyssey Crater and Spirit Point on his blog already. Lot's of fine boulders there. Thanks, Matt!

Stunning view looking east to Spirit Point, and beyond to the bottom of Endeavour. This is our first good look at the "step" up to CY, and at first glance it looks pretty navigable to me - better than most of Home Plate:

Another incredible view, looking south across Botany Bay, to Solander and Tribulation. Sutherland Point/Nobby's Head are just starting to show on the far right (this view was before drive, so from the 2676 location):

Can't wait to see those L257's in full colour... wink.gif

Is it really that lumpy? Or is it an artifact of the anaglyph? If it is, it makes me wonder if the steering actuator might be an issue crossing that kind of relief, even driving backward.

If Occam had heard my theory, things would be very different now.

I was kind of wondering the same thing, Dan. I think Pancam anaglyphs like this tend to exaggerate, but it must be at least somewhat bumpy? Obviously she's been over ground like this before but it may have been a while. (Edit: Not Pancam, Navcam. It's late.)

The bumpiness is reminiscent of the surface of eroded ejecta blocks in the aprons surrounding Santa Maria ( http://marsrovers.jpl.nasa.gov/gallery/pre...cam360_cypA.jpg ) and Endurance ( http://marsrovers.jpl.nasa.gov/gallery/pre...yp_A-B118R1.jpg ) only more so. Can't wait to get a closer look at the "step" up to Cape York -- could be the first new rock type since Eagle and Endurance (excluding meteorites).

Is there a geologist's term of art for "knife-edged upjutting shingles"?
Maybe a sign warning of severe tire damage would be in order, even if Oppy's are made of aluminum.
