One post lost already this morning. Here is another redo of the very excellent MAHLI image with the plastic object.

This is also a test to see if the first post indeed posted

Trying again.

An attempted 3D of the object. Barsoomer and Mann can do better, I'm sure.

LWS,

Yep. It is the billateral symmetry of this plastic object that I find a bit puzzling. I, too, would like to know what part of the rover/air bag/descent lander this would have come from. And yes, seeing more of these in dug out trenches would look rather suspicious.

Forum Moderator Richard,

If you are online, I would like to report a posting bug in this thread.

In going from Page 6 to Page 7, Kye Goodwin's post (Reply Number 120) is missing.

I've lost a post this morning too, but I'll wait to see if it turns up before reposting. Here's something else, non-aeolian sand movement again, perhaps an avalanche.

In the lower left corner a sand slope tucked under a rock slab looks like it has sluffed downward and fractured. I don't see any rover tracks or I'd suggest that the rover drove over the rock and caused the avalanche. Active slope processes again, hmmm?

One theory is the plastic thingy came off the Sky Crane and may not belong to Curiosity either way it does not seem to be causing any great concerns.

FMR Richard,

Six posts have been made and I am not seeing any of them beyond Reply 121. Also, when I click on a Page Number, none of the pages after that number show on the tabs.

I've lost two posts today, although both appeared briefly, I think. Marsman posted that my 120 was there but is now missing between pages 6 and 7, Thanks, but now marsman's post is gone too. I guess I'll try again if this posts.

Now after taking the really good MAHLI image - which also like the HiRISE coverage shows nicely how awfull dusty the Gale crater floor is - it would be time to "test" the chemcam system on "exotic" but not unknown material under Martian conditions. Also he MSL team should also reimage the plastic before they leave Gleneg to monitor UV degration and effects of postulated superoxides for basic material science on Mars. Cool

To me, this looks like a hollow skeleton of "something". If this is a cable wrap protection (that I've never seen before, trust me I've seen much, as I'm an old timer electric engineer) of some kind, think glue... the symmetry of the feature is quite impressive.

LWS a perfect stereo image of the feature, thanks.

And yes, I've posted most of this post 2 hours ago with no result.

Mizar;

Yes. The bilateral symmetry is indeed impressive. But also impressive is the regularity of the spacing of the pale dots on the edges of the plastic as well as the small dark spheres inside the hollowed cavity at the "head end" right side of the plastic. Add to that the striations and we have a mystery as to what type of plastic it was and what it was doing on the rover or the sky crane.

There seems to be a lot of out-of-place litter at Glenelg. Here's something small that stands out clearly as WHITE in a yellow landscape, upper left:

Here's another white bit that appears in two images, center far right in the first, center left in the second:

And here's a third, possibly, not so obviously white but shaped like the thingee we're seeing closeup, lower left:

Good work on the 3D in 122. There is a 3D with a different orientation on UMF.

I think the plastic is similar to what is used in a baggy. It seems somewhat bent and rigid as though it has been subjected to heat. (Maybe the descent rocket exhaust?)

I can't quite decide where there is something within the plastic (wire?) or whether it is just a crumpled part. We can certainly see soil below most of it.

re135: taken the recent observation I guess this white objects littered around the crater floor (observed since sol1) could really be MSL landing "confetti". Though every one on the path should be imaged closely just in case some is "different" - would be sad if we miss some neat MSO (Mars Surface Organism) if present or some odd chunks of ice. Smile

Here is some rather interesting observation from sol64:

The formation middle to upper left looks interesting.

I have little time, so I am posting this from a same post on the 'Exploration of Gale Crater-part two' topic. It has mention of what are late refresh appearances of posts there, as we seem to be getting updates from the server with some reluctance from the server security coding. As I post, the server updates during the current post.

My post here:

[I am now posting reply #24, and I have refreshed and reopened the page many times, with no effect on updating the page from the view of reply #21 as the most recent post. Two entries I made yesterday were on the list and are now missing. Those two entries are counted as #22 and 23. They cannot now be seen except as a count on the index listing for the MSL forum page as numbers.]

This is a altered view of the plastic item with 'auto' adjusted color, causing distortion in true color with such strong original red color. The view shows the slight differences in color of smaller particles which show as blue tinted along with the plastic. Here the view is saturated to 16 points increase, and brightness reduced 12 points as the 'auto' setting is a registry fixed simple increase loss of highlights by a few points, a wrong technique to my view, so I darkened the image slightly.
You can see the plastic tends to blue, as does the smaller particles. The camera distortion 'vignetting' causes the peripheral color distortion. We have a view of a differing content in small items across the images. The red blinds us to the accurate view of two types of material seen here.
.

.

Below is an altered version of the image which is altered manually. It is not accurate color, but has a moderate color and tonal set of limits. Within that view I adjusted the subsections for strong color variation to show there is more than two sets of color items. It is heavy handed and not the best adjustment, but time was limited.
.

.

Below is a list of arrow marked items, from left to right.

The items show cores unaltered in a few.
A small very dark spheroid item.
Very dark thin rings around some small features.
A tiny disk shaped solid of differing color next to a rod of differing same color.

All the above listed items are without any association to the dominating red tinted fine particle covering of most items.
Additionally, most all the dark items, seen here as blue tinted, are without red cover and seen solid as items.

There is one further item marked with an arrow, all red covered and showing a core and outer layer, both affected by the red material changed state or chemistry as alteration occurs.

It appears the brighter and larger items are all in a state of internal alteration at the surface towards the core, or are timed in alteration throughout each mass.

The dark items are smaller, and are appearing unaltered.

Obviously this is an atmospheric or moisture or similar chemistry change of a material by electrical charge or chemistry.

The situation at Gale crater in this location seems much more active than the MER locations.
The basic materials also seem differing.
Where are the geologists on this blog?

MPJ, your post of #137 and image, give the appearance of a clearing by a transport down-slope from the left. Could that be caused only by wind or other non-liquid effects? I can see the tilted material in each layer to the far distance, and to some degree the sun adds to the effect with shadow.
Looks like a slide with margin clearing of smaller items. Drainage, in other terms.

The overhang is a place persistent shadow could be tested as a protection from radiation alteration.
Is the tilt caused by a internal removal of mass, with a collapse? Where is the direction in the tilt? I am disoriented.
Sun to the right side here, but the timing and rover orientation?

Regarding the WHITE in reply 135:

One can see larger WHITE areas on and around the bolder in Reply 109.

I also noticed BLACK and other colors in some patches on rocks and the soil.
Some rocks seem to be covered with strange layers of "something".
