New sol 1785 panorama images in.

Here's one processed in Gimp.

Here's another sol 1785 image that is very reminiscent of the Pahrump hills images, veins and all.

Here's another sol 4823 composite showing similar features to the above.

Barsoomer;

Just a blast from the past to reinforce your comment about exudation of water in another post.

https://photos.smugmug.com/Other/MSL-Curiosity/i-QNVhXFC/1/3f86fe68/O/1317%20vs%201321%20drill%20flows%20anim.gif

My gif of sol 1317 to sol 1321 movement of mud from inside and between crevices of rocks, apparentl ycaused by Curi drilling action, merits some consideration as it shows, perhaps undeniably, that under the rocks might contain significant volumes of mud and thereby possibly water and that compressive action or even making a hole and thereby reducing pressure could cause significant movement of significant volumes of possibly wet material.

Several other of my gifs of that period show the same phenomenon.

Wow, that was a great one, Winston!

Looking at it with fresh eyes, it looks at first as if the rock rose up out of the soil. (It seems to have a larger side face.) But actually I think the soil adjacent to the rock liquified as a result of the vibration and its level surface dropped. The mystery is how some of the liquified soil ended up on top of the rock. Did it splatter or did the vibration somehow allow it to climb the side of the rock.

Barsoomer;

I think some of the soil that we now see on the top-front side of the rock actually exuded through the drilled hole and from the crevice on the right side. Several Curi drilled holes suggest that the exuded soil take that route.

some multicoloured rocks, lamina, veins and soil interfaces on and near a sol 1785 rock.

I can'r help but think that a lot of chemistry is going on now in this image.

Some sol 1802 panoramas posted today. Here's my take on one

Interesting meandering cracks and a bevy of concretions, boxwork veins, etc. Wonder what else is inside the cracks that the soil is disappearing into?

Here is an interesting article on electron-eating microbes:

"Humans and many other organisms get electrons from food and expel them with our breath. The microbes that El-Naggar and others are trying to grow belong to a group called lithoautotrophs, or rock eaters, which harvest energy from inorganic substances such as iron, sulfur or manganese. Under the right conditions, they can survive solely on electricity."

marsman;

Good hearing from you! Any news of Henry?

It gets curiouser and curiouser! Life is likely there and possibly everywhere. Even in Stars.

We know so little, yet argue that our current knowledge is all that there is and can or will be.

Sad!

Here's an X-eyed 3D of a chem-cam scene from today's sol 1805 releases.

Use Stereophotomaker at 200% magnification to see the very interesting ropy suspended veins. Would trapped evaporites on their own do that?

Winston,

I've not heard anything from Henry in quite a while.

With the discovery of bacteria that eat and breathe electricity, I think that our current understanding of what life is - is still very limited.

One idea that eludes many on a "lifeless planet such as Mars" is the idea of non-carbon based life forms; or life forms in which carbon is a minor element in their structure instead of a major one.

The Mars bunny, for example..

If NASA had the opportunity to try the Mossbauer on it, they would have at least known if carbon was a major component. If it wasn't, then that would rule-out the "wayward unidentifiable piece of rover airbag material" hypothesis, since this object would very likely have a Mars point of origin.

The mars hematite shelled spherules and their filaments.. sulfur, bromine, chlorine, iron-oxide (hematite) and no carbon..

Life forms that utilize sulfur in their structure instead of carbon?

http://www.popsci.com/science/article/2011-08/oldest-fossils-ever-found-could-present-new-target-search-extraterrestrial-life

The Viking Mars Life Detection experiments were looking for carbon-based life forms and came back puzzling results. The lack of detection of any carbon-based life forms left NASA, and the general public, with the idea/belief that if Mars doesn't have any carbon-based life forms, then Mars doesn't have any life forms at all.

There appears to have been some movement in sand particals between between the right and left images. Do you know how much time passed between the two images, which image was captured first?

Winston,

I can't find any Earthly examples of suspended ropey veins.

However, there are articles that suggest that sulfur may have played a role in their formation.

Latest Curi images

Pavement rocks look eerily like meridiani pavement.

Marsman;

I've been looking on the internet for years for examples of veins that resemble the curiosity ropy types but have been unsuccessful so far.

Curi has found several images of objects which resemble the Cauliflower silica formation found by Spirit.
