sol 1378 views of fiber 1:

Stringie thingie 2 is not in the 1378 pancam but is in the sol 1932 Navcam views.

My best guess is both are Martian material and not scratches.

It sure would be nice to get a full filter, full resolution sequence on these thingies...

Naah. Not a chance.

There should not be any micro-meteorite strikes on Mars because they would burn up in the atmosphere. However, there could be micro-sized secondary debris from a regular strike elsewhere.

The stain seems to be fading away near the sundial platform. If the stain is soil that has progressively moved from the hidden area behind the platform to where it is visible, then it is pretty much all out now. If this is the case, then we would expect no more growth in the total stain area, but just shape changes from now on.

Since the stain seems to respond differently to the wind than the red dust, I'm wondering if the stain consists of rounded particles that are too heavy to be blown by the wind, but able to roll due to vibration when the rover is in motion. Has the stain shape ever changed significantly while the rover was stationary?

Well, it's visible in shadow, something I had not considered before. That sort of eliminates a scratch or crack in the cell covering, at least for this one.

I have also noticed that the stain does not change much in the right filters and in the left filters, it lightens as the filters move towards blue.

The right eye filters are in the infrared portion of the spectrum (except I think for one no-filter setting). The left eye filters range from infrared through visible to ultraviolet. The stain has always appeared darker in the infrared and progressively lighter towards ultraviolet. That effect seems to be more pronounced now near the platform, where it seems to almost disappear in blue and ultraviolet. This seems consistent with the stain being semi-transparent in the blue region of the spectrum. As it gets thinner, it would tend to disappear in the tranparent region.

That's a dramatic change! The stain has extended a little in the 12 o'clock direction, but significantly retreated in every other direction, and it has become somewhat patchy. The total volume of the stain material seems to have diminished. Still has sharp boundaries, especially in the direction in which it has grown.

Barsoomer>>>

Some thoughts:

Seems strange it hangs around the same area changing shape, must be good Earthen residue to eat up!!! Shocked

It looks like it 'crawled' underneath that wire too and not over it leaving the wire exposed yet its able to travel by spreading itself in a back and forth motion. Something deliberately and on-purpose is making it move around...almost as if its exploring the surface of that particular panel spot. Be interesting if it spreads to other deck locations...which we seem not to have witnessed at all.[but what's under Oppy?] It has been in that spot for quite awhile expanding and contracting in the very bright UV sunlight over the same panel vicinity.

It can't be windy wet dust covering and uncovering in this one particular spot just to expose the solar panel...this can not be the case.

We know the Mars surface has a somewhat hardened subtle cake layer a few mm thick with something magically wet mixed in [review Phoenix pics], and that seems to be accumulated on the deck panels too-so when it [the stain] moves around like this I see the same covering in its wake as the rest of the deck!!!How can this be...a strange wet moving stain leaving no trial-just the same substance it traveled over or through or into? Puzzling indeed!

This movement does tell me something however, but I am not going to guess at it. Perhaps its make-up is in the Martian atmosphere with its real locale in the soil itself so minute quantities would be piked up, blown around and finally gathered together in a collective and attached itself to the surface deck of Oppy-right where the camera can see it!!!How unusual is that?

...apologies for the typo...should read as, 'picked-up'[in my 150 above]OH,and thanks for the pic horton in your 148.

Also wondering at this time about its molecular make-up? Would it have one, does it have one,[of course it does] would it be a combination of various 'wet' materials from the surface and atmosphere-yet so far we have seen the vaporization [sublimation] of the ground liquid from the Phoenix hole pictures...so if this is NOT liquid, what the hell is it? Wouldn't this 'liquid stain' sublimate too?

Don't forget we are the aliens on Mars and this stuff, whatever it is, is exploring too!
Oppy metals and plastic and glass are totally alien to it.

I don't want this stuff on Earth, think about what O2 would do to it...EXPAND is the answer.

When viewed in stereo, it appears the stain material has accumulated into two piles, each with a small but noticeable height above the deck.

The stain now has a lumpy patchy appearance with more thinly covered "gaps" between the main piles.

This suggests the total volume of the stain is conserved and the only thing that changes is the shape. To my mind, this points towards something like magnetized soil or sand that is being shaken into different shapes.

Barsoomer;
Remember when I compared it to dust behavior on flat metal surfaces of our old (1927) John Deere , steel wheeled, tractor. Wink

Ben, yes I do recall that. The observational evidence seems to support that general idea. However, I think the particles must be larger or more cohesive than dust particles; otherwise, they would have blown away by now.

Also, the observation of dx, that the stain can cover and then retreat from an area of deck without disturbing the underlying reddish dust, distinguishes it from ordinary dust. The stain particles may be supported by a small contact area with the underlying deck.

It is also still possible that the stain is a film-like covering over the reddish dust, and maybe it is the latter that is rearranging itself into piles under the stain cover.

Barsoomer; I stand corrected, the particles on the tractor contained a range of dust size.. As the material bounced-jiggled around, on a thin film of fine-dust adhered to the metal , other dust was blown away leaving the patches of larger particles but you could still write your initials in the fine dust remaining.

A sharply-defined dark area to the right of the sundial enclosing a lighter area. However, this area is darker in ultraviolet and brighter in infrared---the opposite of the stain.

IF the stain is a life-form, then from its behavior it would have to be amoeba-like (as I think someone suggested---can't remember who), slithering around the deck in search of sustenance. That would explain its rapid advances and retreats, and the cohesiveness.

In the above 3D image, it looks like a trailing part of the stain has passed under a contact ringing the solar panel. It may have forced the contact up slightly. The main mass of the stain seems to have almost engulfed the raised wire beyond the solar panel.

If this stuff is water based it should have sublimated by now! After all Phoenix showed us that ice is about 2" to 3" under the soil and 'it' sublimated right before our eyes when exposed! How curious this that? This is actually-MARS-that's how curious it is.

What in hell is this 'thing'? Its moving and reappearing at will and deliberate.

Could this 'moving creature' be the smoking gun for all the Mars pro-life activists on this site?

I have seen amoeba move under the scope-slow and reaching out in its non-directional moves-and this 'thing' seems similar, doesn't it?

Yo....Ben. About the tractor, I was thinking exactly the same, except the tractor was a Farmall M. Dust used to vibrate to certain spots on the corn planter lids too.
