Mann;

Yes! They said they stopped and took several pics while studying the object. Where are they? that was 2 days ago.

As you said they should be able within hours to identify what that benign piece of plastic is and where it came from. They have not done so, so far.

Something seems awry. I'm leaning towards thinking that the object is native. However, I think that by spending so much time trying to identify what it was, they have demonstrated a little difference in approach to the Squyers approach with matters of this nature. Squyers would have had Curi trundle over it even while concluding that it was a piece of benign plastic.

You have to remember imaging sequences have to be planned in advance - these basically tell the rover where to point its camera what camera to use, exposure times, filters etc. These have to be uplinked to the space craft, which are usually done in the morning, then that data has to be transmitted - usually later in the day. It all takes time.

Mark;
Re. your 102, We know that and it isn't relevant in this case. The report intimated that they had already stopped and presumably taken the images etc. for the investigation 2 days ago. They have already come out with a conclusion. They must have used something other than the 4 images we've seen so far. Those images had to have been transmitted already. Where are those images?

Actually they could have "fired" the Chemcam system laser at this object after taking some better images of it. They have such a huge advantage with the chemcam over past landers/rovers for quick identification of bulk material. A piece of plastic should be fast and easy to recognize by Chemcam - it also would be a great test of its abilities to measure hydrocarbons (if it really is plastics). Confused

MPJ;

Your post above totally mirrors my thoughts on what could have been done. Perhaps they did it and got some organics and hydrocarbons and took the easiest route by concluding that it must be plastic.

Instead of doing a "test" post, you can often make posts magically appear by adding &refresh to the end of the current URL and reloading.

Example:

[link] &refresh

This used to work immediately but now it may need to be repeated twice or more.

if you zoom onto the large boulder and area around it this image and do some image and color enhancement....:

you can definitively see some WHITE areas. Well white could also be salt but to me it doesn't look like salt. Even the geologists should be curious about this...

Do you see it ?

Ups...now it's visible again. (see above about the white stuff on the large rock in the image)

Regarding hydrocarbons, what if ...(insert an eager face here)... - no. Forget it.

Yep. Since this is Mars, and Mars is a dead dry cold dusty world with deadly superoxides and solar radiation, with virtually no atmosphere to speak of, it just has to be "a wayward piece of rover material or something similar".

However.. On Earth, the above picture would in fact have an entirely different interpretation.

There are new MAHLI images of the mystery object. It definitely looks like a piece of plastic...

Looks like I'm seeing the same posting problem as everyone else. Very strange, indeed.

Unless there are more of them, the plastic explanation for Reply 115 works for me.

It just goes to show now that he is away how much work Hort must do behind the scenes to work around the software glitches this site has. Maybe this post will get lost who knows.

Marsman;

I essentially agree with your reply #117 and the excellent sol 65 MAHLI images show that I was totally wrong in my comparison of the plastic with tardigrades.

It looks like plastic in most respects. However, it would be useful if they could identify where it came from on the rover as there are some features on the "plastic piece" that still need explanation.

Here's a 4X magnification of a sol 65 MAHLI image (Beautiful resolution) that shows detail of the plastic.

What are those small spherical objects on the torn surfaces? Did the crumpling and heat produce these artifacts?

Why does it appear bilaterally symmetrical?
What were the regular ridges caused by? What rover component was it wrapped around that provided the template for the fine features of the plastic?

a few more of them that look like this might be a good test of what kind of plastic it is.

Here's two more small bright objects in the latest mastcam images:

They stand out pretty clearly and don't look like imaging anomalies, top left in the first image, center left in the second. Has the mission spread litter over a large area?
