I think it's fantastic in any case. Opportunity just wanted to show up the newcomer, Curiosity and steal the limelight for a bit. So, if it turns out to be an overturned rock, then it makes me wonder ... Opportunity is not very good at doing that sort of thing on purpose, is it? I mean can it do that sort of thing with its arm, or is that too difficult of a maneuver? Probably would damage valuable instruments, trying to mess around with that.
But for Curiosity, it could repeat this kind of exercise often, right? It could use its scoop to overturn small rocks, I think.
.. And it's really too bad they didn't see the overturned rock for a few days. They were too slow to have seen the hermit crab that walked away in the other direction in search of a new home.

By known crackpot, Rhawn Joseph. This is the same guy who claimed to find alien diatoms floating in our atmosphere which arrived here via panspermia... complete waste of time. He seems to be trying to make a name for himself by claiming discovery of fake aliens. It only takes a brief glance of his silly lawsuit to realize that's what his goal is. He repeatedly refers to himself as the discoverer. Even if it
did turn out to be some kind of alien, he wouldn't be the discoverer.

As long as he doesn't discover any

And they don't discover him and thereby judge the rest of the world accordingly

Has anyone mentioned this object might be a Martian puffball of sorts?

Perhaps these are the stones alluded to in previous posts, but the descriptions which have been provided here, do not make it clear. I think the Jelly Donut is a new chunk of debris in it "after" position. How it got there is subject to educated speculation. That Opportunity "layed a patch" and disturbed the surface material is highly likely and might really be the only true cause of, unless a highly unusual arrival of a meteor nearby dropped deposits here after impact -- all without disturbing the rover. Anyway, there is a formation of three stones which lie approximately 1/5 of the frame below the Jelly Donut. On Sol 3528, they are arranged as a triangle. In the "after" frame (Sol 3540), these stones really seem to be have been rearranged so that they are linear. I posit that Opportunity is somewhat ham-handed in how it conducts studies . . . . but I'm not being critical. It's a hazard of the assignment.

I've looked for updates on this from NASA. I would think the rock and its suspected original location would be of great interest to them. Yet, I haven't seen anything. Has anyone else?

No. I think it is only of moderate interest. They've aimed some instruments at it to examine the mineralogy, but beyond that, I don't think it's creating much of a hiccup in the overall mission plan. I wouldn't be surprised to see a paper in the next year, assuming the mineralogy proves unusual- something that isn't obviously the case.

The Mars rover lead scientist Steve Squyres of Cornell University the other day made the following comments:
[The rock] obligingly turned upside down, so we're seeing a side that hasn't seen the Martian atmosphere in billions of years and there it is for us to investigate.
. . .
The jelly part is like nothing we’ve seen before on Mars. It’s very high in sulfur and magnesium and it has twice as much manganese as anything we’ve seen before. I don’t know what any of this means. We’re completely confused, everybody on the team is arguing and fighting. We’re having a wonderful time!
. . .
It will likely be the target of considerable investigation over the next few days.

And I know they have had the rover sitting there, trying a number of tough movements to bring its instruments to bear on the "Pinnacle Island" sample. Also, they would want to investigate the theory about its point of origin to verify that it was indeed flipped over by Opportunity. 10 years, this rover has been on the planet, and I don't think that in the previous 9.9 years, it managed to do this kind of thing before, at least not on a strikingly interesting sample. They named it Opportunity, and here it is. But I do hope they share some findings sooner than a year from now in a paper, if only to give answers to the questions they themselves raised in the public consciousness.

Things about this that should no longer be viewed as "theory" but as rock solid fact: (1) It's a rock. (2) It's from Mars. (3) It was dislodged by one of Opportunity's wheels. (4) This is part of the indentation in the ground where it used to lay:

Thanks for that additional info. Although I am pretty convinced that this is the correct explanation, I suppose for due diligence, a better image of that purported point of origin, and the space between that point and the final resting place should be obtained. I would look also for signs of the rock having bounced or rolled through the area, consistent with the slope that exists, which must be able to be determined quite well by the rover's team. In fact, I wonder if some really clever person could deduce from such information a weight and density of the rock.
Anyway, I still find it wonderful that this rock shows such an unusual composition. I would think that it might be a good idea to add to Curiosity's protocol to try to overturn or dislodge some small rocks on purpose, if that was not already in the plan. I think it seems a very interesting source of new information ... a little different than digging in the sand.

When the latter had also been worsted in the fight at Plataeae, and had taken flight, a rumour got about that Mardonius had left an immense treasure buried in the ground near his tent. Incited by this prospect, Polycrates, a Theban, bought that piece of ground. However, when he had looked for the treasure long and thoroughly, and had made no progress, he consulted the oracle of Delphi, as to how he could find that money. Apollo replied in these words '
Omnem moVERE lapidem (
Leave no stone unturned)'. As soon as he had done this, he found, they say, a great hoard of gold.>>

Ah, there we go. So it wasn't just plucked from that earlier indentation (if at all) but originally broke from another rock and there's the other rock. That's a satisfying picture.

Why is the image cropped, in SOL 3540, right at the piece of small debris, similar to the Jelly Doughnut mater composition, compared to the FOV of SOL 3528. Something to hide? Just a thought. Would love to see the full frame...
