Kye, this 3D might help you.

Sol 3349 ( Jun 26, 2013 ) 3D false color clast survey in Botany Bay:

And here is a 2x6 MI pan of Black Shoulder:

with links to Location, 3D pairs and a montage of 3 2x2 panoramas.

This is the last leg of the Botany Bay leg of the Traverse. The Sol-3376 stop is where Oppy is doing the IDD work at site Black Shoulder. A dark-toned, elongated, shallow depression of unknown origin, which I have informally named "The Channel" and which contains the type specimens of the rock "Black Shoulder" and others, lies to the immediate south. Hopefully Oppy will stop there on the way and smell the roses.

At the bottom edge of the image is Solander Point and the target point is the bluffs on the Eastern (right) side of Solander, which I make to be about 170 meters from the present location.

Here is the sol 3376 ( current position ) official traverse map - released July 25, 2013.

It is now sol 3382 a little after 8AM LST and NO scheduled activities yet posted on the tracking site.

Sol 3381 saw the start of a LOOonng APXS integration. Perhaps that is continuing today along with more image downlinks before the final push to Solander. ( And a new topic! )

***NEWSFLASH!

The tracking site was updated a few minutes ago and today's plan is:

4. What EDRs did we request?

Expected EDRs by sequence number and image type:

YAY!

The RAT will be used before another series of MIs and APXS measurements.

I have been studying the Black Shoulder MI 3Ds and I have one crop that is so suggestive that it should receive an "R" rating. I may be looking too hard. If you want to see it you gott'a pretend you're still interested in Oppy after nine long years and ask pretty please.

Yes. Certainly. By all means. Pretty please?

This site has something for everybody, no matter which side of the fence you are on.

But I'll bet that the APXS data cards will be played very close to the vest until LPSC 2014 (or later). And since Oppy is only a couple of Sols travel time from Solander and only a bit further from the "winter haven slopes" I wouldn't be opposed to spending as much time in this unique area as possible.

Certainly this is within the Mission Objectives, which at one time were in part to: "Search for geological clues to the environmental conditions that existed when liquid water was present" and certainly the suite of rocks we are in suggest and era when Mars was warm, wet and habitable. Phyllosilicates, as interesting as they are, suggest the chemical weathering of volcanic rocks or impactites.

But enough...

Sol 3382 ( Jun 30, 2013 ) 3D closeup of RAT over the voids in the rock "Black Shoulder" in Botany Bay:

The RAT operation lasted for 3 hours - so I'm guessing it was a grind and not just a brushing.

The remaining bit on the RAT is a very scarce resource after 9 years of use - so the team must consider Black Shoulder rock a very important rock.

While awaiting the MIs I will put together a little discussion of the voids of Black Shoulder in 3.2.1.

Yep, it was a real light RAT, which is why I said Brush??? -- they barely nipped the top off'n those vesicles. 3 hours? Either it is reallly hard rock or they used a verry light touch on the RAT tool.

Looking at Hort's 2x6 mosaic in reply 161, the RAT/Brush is centered on the boundary between the second 2x2 panel and the third 2x2 panel (ie, about 2/3 the way down).

And here is sol 3376 3382 ( Jul 23-30, 2013 ) animation of the RAT of the rock "Black Shoulder":

Fully agree with Bill. I think the "light touch" was another attempt to section a berry - maybe this one?

This is my reply 165 "R" rated 3D closeup. I think it is another example where "Horton's Hypothesis" ( "IF a weird shape repeats an improbable number of times THEN it is reasonable ( but NOT scientific? ) to conclude that it is biological in origin." ) is applicable.

Notice the complexity of the area surrounding the area surrounding the berry - still inside its "void".

Now here's an "empty" void:

again, notice the complexity surrounding the void.

At first I thought an escaping gas had burst open the voids:

notice the void sides pushed aside - and again the surrounding complexity.

Here is a collection of voids where the openings don't look wide enough for a berry to have "just" fallen out. ( UP is to the right ):

and here is more complex supporting structure around empty voids:

The supporting structure is strong enough to last long enough to fill with SOD:

Are we "seeing" biology at work?

One MI of the Rat/Brush is down:

I'm not sure if this is a long gentle grind on a hard matrix or a long gentle brush on a soft matrix. My initial inclination is to think that the matrix is unusually hard. We'll see...

If you look at the overlap 3D between the full and partial MIs you can see that it is a grind. ( clean, flat surfaces across many "peaks" )

I noticed those "mesas" and agree. OTOH, if that material is soft and friable like a chalk or a clay, it could have done that with hours of brushing. /Devil's advocate off

We'll see-- all we have now are bits and pieces and fodder for speculation. I can barely see where we were and where we are going with this.

It's major, though. No doubt Steve Squyres will make a JPL or Planetary Soc Update announcement of this "never-before-seen-in-the-annals-of-planetary-exploration" finding soon. I'd guess that the next PlanSocUpdate is 4-5 days away.

Hort;
Thanks! Some compelling images. You've excelled yourself.

Note the fine downy light surfaces of petalled "rocks". Also the uniformity and spherical nature of the "dust" in the cups.

Pity Steve and others are almost certain to conclude that they we are looking at just rocks from the analyses derived from imperfect and old instruments.

I forgot to add above that I suspect we are once more seeing another manifestation of a berry "bio-factory" under slightly different environmental conditions to the ones near erebus.

The action we see may be in this theatre now not a few billion years ago.

Sol 3382 ( Jul 30, 2013 ) MI closeup panorama after a RAT grind on the rock "Black Shoulder" in Botany bay:

and here is a link to the before / after RAT animation.

There are systematic registration errors in some areas - but when the 3D of the RAT becomes available I will do 3D animations of selected areas.

The animation is quite large so be patient.

I am still trying to make sense of the changes.

Lots of stuff was covered up or moved and of course the lighting is different and the perspective is slightly different so be patient.

There is one curious spot uncovered by the grind that looks so much like a trilobite fossil that if I were in the field I would clap my hands with excitement.

Have fun.

This will be a challenging one to match up for the before-and-after. Lots of questions.

One puzzlement is that the cuttings from the RAT grind blend in well with the native rock background. Odd, because the cuttings are typically lighter or darker. Says something about the minerology-- remember the streak plate test from GL101. I'd like to see a color L257-R721 Pancam series-- I'll suspect that the cuttings are "burple".

Speaking of Pancam-- on tap we have:

Your "trilobite fossil" bears the familiar U-shaped (or cigar shaped) SOD pattern.
