The MASTCAM R view on Sol 929.

Another take on the extended R-MastCam mosaic from sol 929. I tried to add the images from 926, but had stitching issues, working on resolving those (edit : link repaired)

it would be nice to have a swarm or rovers or a rover with a drone scout

Luckily, the drone scout might just be on its way.

A (probably failed) attempt to find fluorescence in the Sol 935 MAHLI night shots:

Starting from this Sol 935 MAHLI white LED night shot, RGB channel-wise histo stretch returned this image:

Starting from this Sol 935 MAHLI uv LED night shot, perliminary cleaning by subtracting a Sol 910 night image without LED returned this image

then RGB channel-wise histo stretch returned this one:

Subtraction of the histo stretched white LED image from the cleaned and histo stretched uv LED image returned this image:

Histo stretch of the difference image returned this result:



In the latter image I wasn't able to indentify fluorescence or phosphorescence uniquely.
Most variations are probably due to shadows and slightly different positions of the LEDs (my preliminary interpretation).

The newly brushed target (Sol 936) close to the complex Garden City vein seems to be very soft again (well-scratchable by the brush).
The rock contains grains (clusts, concretions,...) which appear harder (more erosion-resistant) than the matrix. The interior of the rock looks greyish relative to the rind.

The same brushed target as an anaglyph.

This is a really zoomed in crop, my brain/eyes can't make sense of anything any closer.

The detail is great, the only problem is that I can no longer focus on my keybooorf!!

Two more MAHLI images as an anaglyph, from Sol935

...

For left red, right blue, I'd say the channels should be exchanged.

The newly brushed target (Sol 936) close to the complex Garden City vein ...

If this were an image from Earth I would be querying raindrop impressions. Not suggesting they are, just noting the similarity.

The same brushed target as an anaglyph.

In the meanwhile the focus stacked version is available (anaglyph version) :

The motor count of the single image is 13961.
Here a version with the derived scale:

The size of the grains seems to be between about 0.5 and 1.0 mm.

There may be some fine layering.
My favorite interpretation would be a sandy mudstone/siltstone of fluvial (velocity about 30 cm/s) origin.

My turn to add a scale: I used the motor count of sol 930 MAHLI pictures to derive the scale for these mosaics of veins at Garden City:

Any way you cut it the rock is black & white. Seems this area is a mantel breach of some type. The black rock being mantel basalt.
