Hopefully, they'll be able to collect some APXS data, at least, in order to see whether it's actually some kind of iron mineral, or some SiO2 modification, instead. The latter could fracture in a conchoidal way, and then appear specular, too.

Facebook post from 'NASA’s Curiosity Mars Rover' (January 4, 2018)
"Meanwhile, back on Mars... I’m checking out these stick-like figures. Each is about a quarter-inch long. Maybe they're crystals? Or they could be minerals that filled spaces where crystals dissolved away. Stay tuned! Science continues."

Noting a few apparent 'breaks' in the apparent layer remnant, did it get run over? its revealing brighter material inside almost as if its some sort of piping condensate. aside from that is an almost vertical line of 'etched' graininess to the right of the main leg and most visible in this sol1922 image, looking almost like an extended REMs strafing. heres cross/parellel stereo of the two main sections from a sol1923 pair.

My first thoughts were contact from the rover as we can see the sand around the target was disturbed, but I dont know if the wheel ran over it during its travels 1903-1904 or when it returned on 1912. It could also have been in contact with the APXS as they used it on this target

I never did post a circular version of the 1912 navcam panorama - this is from Damia's version.

I have a request from my friend Nick Schneider, who's a coauthor of a popular astronomy textbook, The Cosmic Perspective. He's looking for a publication-quality illustration for the latest edition of the book, that shows Curiosity's route of ascent of Mt Sharp (current and projected future) superposed on an oblique view of the terrain, ideally something like one of Sean's wonderful renderings, but with the route shown something like Nogal's post #245. I suspect that an image focusing on the traverse from Bagnold Dunes onwards would be ideal.

I don't remember seeing an image exactly like that- could anyone point me to such an image if you know of it, or would anyone like to volunteer to generate one?

Thanks,
John

As a note, I can see the correlation now between the terrain in Sean's rendering in post #242 and Nogal's view in #245.

Has anybody taken a crack at DeBayering and assembling the sol 1911 MR panorama of the interesting "blue" outcrop? According to Abigail Fraeman in the sol 1911-1912 update:
QUOTE
This morning we found ourselves back on familiar ground, near the targets "Lismore" and "Leadhills" that we imaged back on sol 1905. We drove here to take a closer look at the transition between the blue-gray and red rocks in order to understand the geologic processes that may be responsible for this color change. Since we pulled up right alongside this transition, we were able to plan a monster, 180 frame Mastcam stereo mosaic that will cover the entire area with very high-resolution color information. Downlinking all of these frames from Mars to Earth may take some time, but fortunately we'll have some great opportunities to get big data downlinks during the upcoming holiday. I'm very much looking forward to spending the break unwrapping the data bundles and seeing what's there!

Here is a possible contender for the notional route map... this one is only good from mid Murray Buttes though


Interactive / zoomable version at Gigapan

MSL Traverse Map v1 covers the whole route plus incorrect notional...


Interactive / zoomable version at Gigapan

It might be possible to update with a new render depending on when it is needed.

Here is the full monty over on Gigapan

I didn't futz around with the color too much, other than an exposure pass.

You really can see the color variation from red above to less red below though. Nice work, and thanks!

Holy cow, that's a lot of pixels! I can probably produce the map that John/Nick are looking for, but not until after I finish this wretched Curiosity update.
