According to the data tracking web, more MIs are planned for today (sol 714) and tomorrow.

Hmm -
More L6 shimmying Pancam goodness - did I miss the memo about this technique? Oppy seems to be imaging the surrounding detail in this manner - is this for a parallax thing or a super rez composition? It looks intentional... I made a QuickTime movie to show the effect:

QuickTime File

EDIT - File is much smaller and should stream now - sorry about that

More "super res" I'd say. I did play around with those most recent sets of images (6 sets of nominally 16 images each) but I was not satsified that I could really do anything better than reduce the image and jpg noise by stacking the images (which of course is the whole point of stacking when used with low signal/noise astronomical images.)

I'll have to experiment a bit more with "drizzling", but early attempts created too many image artifacts. I'm using the (free) RegiStax software, so feel free to join in :-)

The key to using that software seems to be in disabling the wavelet filtering, which I was only able to do by selecting Gaussian (I think) and then setting all the filter params to 0...but there must be a better way?!

It's super resolution imaging. It's hard to make it worth-while when you use the JPG's - but if you have the RAD's it's quite a 'profitable' exercise. They did it back at Bonneville with Spirit looking at the old Heatshield - and I barely got any results using the JPGs -but using RAD it was much much better

Can you show these super-res images of heat shield, Doug?
(I obtained poor results with old jpegs, I recall)

Whew, I'd forgotten the tremendous results that you got from stacking those heatshield images. The images of these crossbeds ought to be fantastic when stacked, especially with the low-incidence lighting they used.

Did they have to retake ALL the MI shots? Some of the earlier ones did appear a little out of focus.

Here is an odd Blueberry.
Not the 'half-berry' but the little one next to it. odd because it looks as if its erupted, its not as round as most but its got a strikingly blueberry-like 'top' to it, harking back to the blueberry 'stem' idea raised almost two years ago (!). Strange that its got so much textural contrast between the hemisphere, like Mars itself. well, it looks almost like a strawberry from this angle, guess we need a better look from a different angle...

I may be wrong, but I'm guessing they are doing it on purpose, so they can create a 3D model of the outcrop.

Finally, a panorama of Upper Overgaard.

"Science team members next plan to adjust the rover's position slightly to conduct microscopic analysis of another target area, nicknamed "Upper Overgaard."

Atomoid's odd blueberry is obviously a blueberry flavored yogurt-coated-rasin.

Tried to make a superres from one Sol712 sequence... results still below my expectations, but some fine detail are more clear:

Lovely! Now, is anyone prepared to point out convincing festoon cross-bedding in this view? I'm not.

I'm not convinced by the cross-bedding interpretation, never have been. The only think I ever thought looked like it was the 'unconformity' in Endurance. Maybe aeolian cross-bedding cemented by minerals precipitated out of ground water. This - for the most part it looks like parallel bedding exposed on an irregular surface.
