The image at reply #59, at 2X size and higher dpi, a little blurry but the small vacuosities are so numerous and the patterns of missing material so interesting.
It needs a color re-balance and other processing. Not sure of the storage time limits, you may want to download a copy to work with.

Correction for reply 61 above. Initial host links do not work. Disregard 'links' at #61.

Re reply #63. Great 3d! If I found this here at home I would say it was the work of Carpenter Ants or Termites. But this is Mars; right?

Have a great vacation Hort. I'll miss your work here when you are gone!

Re. Hort's #63, assuming that it isn't a vesiculated basalt, could diurnal driplets of water over huge time spans produce this? It does'nt look like wind erosion to me but who knows? It might even be martian termites.

I believe that is the same two pieces in my images where the apparent spheroid embedded seems to be a matched pair with symmetric recesses and a transecting split across the middle. I presented it in The Exploration of Gale Crater as a series of closeups. Without altering the color balance to give more true color, and then added green, it was not standing alone in the materials. One part was just a partial section, but the example viewed here is nearly complete.
Sure doesn't look like a rock or spheroid to me as minerals only.
.

.
The more complete views are more convincing with added matching details.
Can this be a type of mineral spheroid?

A lot of dust seems to have accumulated already on one small area of the rover. Here are images from sols 16 and 60:

The dusty area is near the far edge of the deck where the largest bundle of cables goes into a connector. On both sides of the connector there is already dark dust or soil on the deck evident by sol 16 and the dust seems to have changed by sol 60. A clean band has appeared by sol 60 across the dusty patch left of the connector. I see many fine parallel or diverging lines in the dust on both sides of the connector in the sol 60 image. We'll have to keep an eye on this.

Ref., Kye at #68 above, I made this enlargement to view the dark soil lines set up by some action on the rover deck. Kye mentioned the cleared area at the right, and implied the action was altering the soil surface on what I presumed was a smooth and fairly clean deck of Curiosity.
As the tilt from travel may be a few degrees, and some vibratory or rocking motions may be occurring in travel, is the clearing and the dark 'oscillation' type lines pattern set up by wind and motion, or exclusively one or the other?
I see at the far right side in the enlargement here, a matched physical relationship between small dark gravel sized pieces at the outer limits of two or more lines, and the match is nearly perfect.
Do these varied sizes of objects set to a vibratory oscillation distance, vertical, rolling, or horizontal, or, is this the wind tails and local vortex type wave action almost exclusively?
At the cleared area, far left, I see a differing banded less visible pattern along the cleared zone side margins.
Possibly a fixed size soil particle has a self sorting process as they would down a slope? In that possibility most any of the motions could set up a pattern from various sources of stress?
Ben should explain this for us in context to the presumption that order is not self induced as has been claimed in past years here on the blog. Most of the dust cover on pebbles and rock is patterned very well at Gale thus far in image closeups. That scale of lines is different from this view on the deck.
Kye indicated sol 60 for this original ncam image. Front right camera, I believe.

...........
I also made a mistake when uploading some of the reply #67 images of the symmetrical 'spheroid' object, and marked the closeups as MAHLI. They are actually mcam, mastcam images of sol 57, and I have uploaded corrected Id's on the descriptions at the image host.
The symmetric patterned object seems to be a 'discoid' shape in 3D, although not sufficient images were taken to know that with certainty. As a flatter object, and not a full spheroid, it would suggest the two parts are more a crinoid type object possibly with a flat plane weakness causing the two patterned objects to separate unless formation is common as they are, in flat discoid full shape as seen embedded in the rock or mud-stone. What size would a mcam image indicate for this distance to the rover deck margin, at the elevation of the ground around Curiosity? We would have to know the mast elevation and particular camera information.
I find it hard to guess what large pattern this object could be.

Context image of the 'mud-stone' of sol 57, with the 1 or 2 symmetric discoid objects. As the date is past, it appears there was no interest in MAHLI imaging or chemistry testing.
.

.
I am trying to find the distance of travel from sol 57 to sol 61. A sol 59 image appeared close by.

...........
This subframe mastcam image of sol 57 shows similar lineated ridges across the dune windblown side, nearly matching the rover deck dark ridges shown in the entry #69 & 68. I find these matches of pattern too close to be discounted. Does the source material cause the building of ridges and troughs at regular intervals? Much of the local solid stone has surface ridges and internal structure of a same or similar type.
Are the four displays all one influence?
Dust.
Dune textures.
Rover deck.
Rock mass texture and structure.

Hort I did not get your holiday request form get back to your computer now and create your images don't you realise how many thousands of people are waiting in anticipation?

Seriously have a great break! you shall be missed.

Kevin, ha ha...

I am in Phoenix now, waitubg for my cousin to fly in from WV. Her plane was delayed an hour in Minneapolis so I have some time to kill.

Terminal 3 lost power about 15 minutes ago and nothing is working - except the internet connection. I wonder how long the servers can run on battery backup?

I better post this now before...

Anyone catch the update today? Is the object at the centre of today's two ChemCam images what they think may have come off the arm? Looks like a bug to me. I guess it could be a peice of tape. Too grainy for me to tell for sure. Maybe a bug hitched a ride from earth? Sorry; I couldn't get the image to transfer to here.

"Curious" little object photographed by the Curiosity rover while digging in the sand (near centre of this close-up image). In other images, looks brighter than surrounding sand. A piece of something that fell off the rover?

Curiosity has temporarily stopped digging to look at it.

Yeah, your post hadn't appeared yet when I did mine, but glad you saw it too. Lots of discussion going on elsewhere.

It looks like it is dust free and has a plastic feel to it. I hope they will use MAHLI and/ or the laser to find out what it is. Does anybody know the measurements of this object?

CHIMRA has downed tools because of the mystery object which seems to be a bit of tape or insulation.

Here's a rotated 3D (of sorts) of a crop from the two Chem cam images at 1.5X magnification. 3D resolution not particularly good, am sure Barsoomer could do better in Hort's absence.

It doesn't look like something that just dropped from Curi. Seems well set in its ways. Looks more like something that was there before, or an artifact from laser zapping. IMHO.

MPJ; Interestingly, If this was Oppy they would have moved on without another look. Perhaps there's hope yet for Curi.
