Tau, it strikes me that the thing these rocks have in common is movement and impact. In the last image of the series it seems to me that the two areas arrowed fit together and were internal, possibly along a dust filled crack in a larger rock that fractured when falling from a higher position. The third image could be impact compression from rocks falling from the imaged ledge. Alternatively it may be thin sections of tachylite (basaltic glass).

The sol 168 pan is now available so here is a circular view.

I rather suspect that the coatings and patches were created in calm conditions, probably as fracture fillings, maybe even with the presence of water.
This smooth coating in the picture below reminds me of coatings when water with dissolved minerals runs over rock surfaces. For better visibility, the coating is colored blue in the right image.

By the way, when I first saw the raw image, I wondered why parts of this rock were out of focus and others were not. Until I recognized the outlines of the smooth coating that creates the out-of-focus effect.

It does remind me of travertine. Though given the local chemistry I'd think more like a calcium sulfate (gypsum or some vsriation).

One of the 'All Sky NavCam frames from sol 171, captured a nicely lit section of Séítah's sand dunes (ripples?) on the north side of the rover.

Reminiscent of Oppy's great trek across the dune fields of Meridiani...

How tall are those sand dunes?

After another long drive we now have a few more images. The next science waypoint (layered rocks) is only ~50 meters due west of the rover

Here is the Sol-173 Navcam panorama. I wish I had more time to work on these full 360 panoramas. Other priorities that are going on in my life kind of preclude that. Also these binned 2x2 image tiles are a lot of work and even more so, merging them seamlessly into a 360 degree pan. I am trying to work out an optimal and fast workflow for these.

The tall outcrop in the Sol 175 Mastcam.image is Artuby (see the current Route Map above). And in the foreground is an expression of the the Parallel Lineations, along with Micro Imager mosaics.
We may spend some time here.

--Bill

The rover was tilted at ~20 degrees, they may have considered it too steep for contact science?
They drove away from Artuby during sol 177, heading further WNW between the ridge and the sand dunes (est >85 meters)

Back in the saddle again - did I say saddle? I meant harness. (Virtual Mars Bar if you know where that comes from without googling it)

This is the sol 175 panorama in circular form. Very tricky to fit this one together. I wish we had just a single full frame Navcam for each sector instead of four quadrants individually stretched. It makes my job much harder.

Anyway, already moved on now - more later and a map update soon. Tomorrow will be the first PDS release for Perseverance and I am hoping the Analyst's Notebook will be up and running right away, with lots of new target names.

Undoubtedly. I saw that rock but didn't perceive that talus with slip failures. Good place to get stuck.
But this was our first encounter with a good exposure of the Lineations. We got multispectral and micro images here and we'll encounter it again up-trek (or would that be up-rove?).

Sol 177 sunrise picture. The first ever of its kind. The sun is overexposed yes, but we have everything, like the blue haze around it, and how the diffusion of light is made through the atmosphere.



Also, Postcard version :

Really nice work Damia on stitching these Navcam pictures! No seam, perfect job
Here is my take with only 3 of the 5 pictures.

There seems to be a slight asymmetry in the sky glow, as though something over the horizon is casting a shadow on the atmosphere just to the left of the sun.

I think it can be the result of a sligthly incorrect flatfielding correction in my case.

Right - if you look at the original frames:

https://mars.nasa.gov/mars2020-raw-images/p...1_01_295J01.png
https://mars.nasa.gov/mars2020-raw-images/p...1_01_295J01.png

the sun is near the edge of the frames so the shape of the glow will be sensitive to vignetting (and uncorrectable when the glow is saturated).

Looks like you're right. My dream of Martian crepuscular rays is shattered...

John

PDS release today - the Analyst's notebook is not yet ready (alas) but among the goodies is a table of Supercam targets. This is a very condensed list (omitting duplicate names, long distance imaging and calibration shots). I think these are all LIBS targets (except 'Heli' which is the helicopter, presumably, though I have not checked yet) but some might be just RMI images not labeled long distance.

Mission update (blog) from Kenneth Farley dated August 20, 2021
'Roubion - The Problematic Weathered Paver Stone Perseverance Failed to Core'
Adresses: 'Rubion', Citadelle, and the possibility of continuing the westward trek toward South Seítah, then heading out the way we came, and possibly have another go at coring CFFR.

Very nice, James. Here is my circular version of the full sol 178 pan.
