Horton's rep 120 image reminds me a lot of the images taken by the Phoenix optical microscope, which had a higher resolution than the MER MI, and showed black, red, etc. particles in greater detail.

Barsoomer;

Yes the Phoenix OM images look a lot like these SODS here.

Perhaps a review of the Phoenix images might be of interest.

Sol 0364 animation of chemcam laser zap of SOD in the soil:

Sure would be nice to know if the SOD has a different chemical signature than the dust.

For example, is there more hydrogen in the first few zaps of SOD compared to "just" dust?

Of course, that implies that you see a difference in the soil between SOD ( a network of short interconnecting rods ) and dust.

I don't think I will live to see anyone within NASA ever admit to seeing any difference.

Interesting how the laser caused the "rock" in the upper right corner to have that dark spot right in the middle of it. Haven't seen that before. Oh wait.

Would someone with more imaging prowess than me PLEASE build on this?

That's the "plastic" from Sol 65 and Wernecke from Sol 169 (or close to). It's obviously identical.

Clearly, it is not a piece of plastic. It's a unique feature associated with a very particular pattern atop rocks that somehow manages to repeat itself about rocks whether on sand shadows (Rocknest) or mudstone from a formerly habitable lake (YKB).

It's not by accident they brushed off that area of Wernecke.

What are those light coloured specks on this CURI deck instrument. They are not dust.
Could they be solidified water droplets? life?

The picture is a crop, magnified by 1.5X, from a sol 367 Mastcam image.

The image below shows a rotten rock.

Wonder of CURI will investigate this further. I think it offers a good opportunity for CURI to do a thorough analysis of a rock type that is relatively uncommon (some were seen by Spirit) and it might just offer some revelations about influence of water, biology and time on certain rocks.

There are some interesting uploads of a strange rock by CURI today.

Here's a white balanced x1.5 magnified thumbnail. The full treatment seems to have been done with this rock

Waiting with bated breath for the full version

The detailed images to the thumbnail at #132 were posted tonight. A bit disappointed that no hyphal like textures were seen. However there were a few clearly spore body like spheres in the top 1/3 of the rock mixed with the typical dust.

Below is an x-eyed 3D, white balanced that shows clearly that the are that looked like hyphae in the thumbnail is not so and that also shows the small dark spheres. Roam in stereophotomaker at 200%. Interesting structures.

Barsoomer, thanks for the link above. So the blue/green bubble mats of YkB are thought to be just that: gas bubbles. Of course gas was released due to UV-photo-oxidation et cetera in ancient times. Wink

Jpeg of the the sol 373 crop I posted on Wildcat's topic.

Note small discrete spheres that are different in colouring and shape from the SODs.

Sol 0380 panorama ( HD format ) looking south:

I wonder if the rover will take the straight line "goat path" on the right side of the depression ahead?

Note the interesting rectangular blocks in the foreground.

And here are a few recent chemcam / mastcam 3D images from sol 370:

There are some interesting details in the first one - but the mismatched shadows make them very difficult to see.
