sol 0057 Navcam study:

You have to read the Flickr comments to understand what you're seeing.

sol 0056 montage of enhanced difference false color images of the soil:

I see the usual "fairy ring" patterns that no one else sees in fine soil. But it's OK that you can't see them. Really. It's. OK.

and a sol 0057 Chemcam flat field "pan":

I don't know which rock this was. It doesn't matter anyway.

Hort;

I think its from this rock

If I zoom into the chemcam image after some image enhancement I can see two kinds of black spots:

1. Holes (shadows) of various sizes and greylevels.
2. Dark spots in narrow size range. They seem to have the same color (greylevel) level. At least in 2 cases the spots seem to consist of two cone shaped cavities close to each other. The edges of the spots look frayed.

It's a bit subtle ... I wonder if anybody else can see it or if I'm just overinterpreting here.

sol 0057 Chemcam rock:

with location link.

I don't see this location in the sol 0056 mastcam thumbnails and the rover moved on sol 0057. Perhaps a "documentation" mastcam image was taken - but has a very low priority. Maybe see it when the French guy needs it for a paper - in a year or two.

Thanks for spurring me to look after you presented your guess, Winston.

Yes, chaosman, the laser zapped holes look "different" and the area around them usually looks different too. Hey a plasma fireball erupts from the rock. That's gott'a hurt.

Hort; re. your reply #48

Way way cooooool!!

I have no doubt now that Curi will establish habitability at Gale crater. Indeed, I think your image might be the first indication of family linkages between the spherical meridiani berries and the uniform mini berries or pebbs now being imaged here at Gale. These miniberries appear to be also superficial but they appear blue only viewed in the soil. There are numerous short discrete small filamentous particles that could fit the original agreed morphological characteristics of exo-life before that goal post changed.

I was going to post some of my images of the soil study but I was upstaged by your magnificent ones above. But perhaps there are one or two that I could work up to show the particles that I think could be represenative of martian life just below the surface at glenelg.

Beautiful images again

Wow, I'm feeling overwhelmed by the pace again. The close-up in Horton's 48 shows a very uniform surface layer of granules about one to a few deep with a great depth of material underneath that is much finer. It appears that there are very few granules mixed with the finer-grained soil. This is not consistent with the ripple being a granule ripple as on Earth. Granule ripples are usually a mix of sand and granules all through, in section often showing linear granule concentrations along past surfaces.

I think that the surface granules are being slowly lifted up by fines that slowly accumulate underneath the surface layer. Desert pavements on Earth are now thought to originate in a somewhat similar way.

Here's the image from Hort's masterpiece above that I think shows several repeating shapes reminiscent of filaments and of similar size and orientation in the top porton of the subsurface.

So it looks like the next two weeks or so will be spent here at Rocknest and the team will deploy Chimra and develop the best techniques on how to use the scoop how to deliver samples into the Lab. Chimra has carried a film of oil from Earth and therefore this will need to be cleaned off. So they will scoop several times and flush it though the Lab also a bit like rinsing out at the dentist. No great science is expected as the samples will be contaminated and there is nothing too unusual about the sand and rock here as it is mainly Basalt.

Great news kevin!

I will be leaving early Sunday for a week's holidays ( lots and LOTS of pictures with my new camera ) and will be busy when I return post-processing the images and putting together a little show.

With the extended study planned for Whitewater Lake and this one at Rocknest I will not miss much on Mars.

Maybe the MAHLI team can practice doing 3D MI correctly while I am away. For extra credit they can try perfecting 3D MAHLI panoramas! Forget Mastcam panoramas. Do it RIGHT with the MAHLI pano-head ® (patent pending ).

Does anyone here have links for ID of filaments or fibers which have well shaped spheroid tips on only one end, are all the same diameter, and have the same tonal characteristics, from basalt or syenite type amygdule sources?
Also similar arcing fibers of similar diameter which are in arrays. These are even radiating from the single preferred sides of very dark smooth or glassy textured oblong spheroidal shapes in matched side by side examples. Multiple patterned items.
What mineral is dark, glassy, and grows fibers from it which are bright, arcing, and all of the same diameter?
Do these sound like Earthly crystalline mineral assemblies?
Looks unique to Mars, perhaps?
Did they originate as an eroded massive material or form in place from the soil?
I understand the magma such as syenites and others can carry the fingerprint type papilliform surface texture and internal banding.
Do the fibers of several types also exist on Earth as examples with micro-spheroid tips on one preferred end, and alternatively, radiating directional arcing types, associated with dark amygdule oblong shapes?
Surely there are examples on Earth if minerals?

Will some Mars minerals be unique?

Have a long and safe travel, Hortonheardawho.

the image in re:47 shows a curious pattern on the rock, looks biological, like lichens or some other microbial colonization. The giveaway is the collection of small round spots clustered together. Each round spot would be a colony of something. It does not look like a typical mechanical or chemical weathering pattern, because the patterning is in spots which to me indicates biology, something starting in the middle and growing outwards.

r lewus et al. the SAM/Chemin results of the rocknest material are going to be very interesting! If organics are detected this would be the real first surprise with interesting indications.

If even a place like Gale crater - which I think is the least habitable place (nowadays) of the last landing site candidates - contains organics (biologic or not) this would tell us a lot of the rest of Mars.

Can someone explain this image content to me.? This is from sol 57, the Mastcam camera. Apparently this is a scene in preparation for further scoop evaluation of the shallow soil drift where the wheels are testing the density, and a altered clump of some source has been chosen for viewing. Where is the content of this clump after initial imaging here, and how does this three dimensional clump form?
What is the effect of challenging the internal content of this clump?

Will we see the scoop effect on the clump later?
Is this effectively a mud based clump or an altered solid object now powder?

If you at the pebbles on the rover tracks in the MAHLI images, you can see that they come in different colors: Greenish, Yellowish, Reddish...

There is also so much different colors in the soil. It's like small scale pattern.

To me it looks like the entire surface including the pebbles is covered by a thin colorful "something" layer. It kind of glues the upper surface.

That layser is then coverd in some kind of dust.

Would be interesting to see an undisturbed surface using MAHLI. Could the dust be gently "brushed" away by the rover?

Another opportunity would be close to the landing site...
