I didn't realise straight away that the sol 102 drive was a fair distance.
It was also mentioned that there was a touch-and-go, which I assume was before sol 102's drive: https://twitter.com/spaceroboticist/status/270417794376548352/photo/1
Was the touch-and-go with the APXs?
Yes, it was.

I should remember to check the Astrogoelogy news site more often. Some very rare up-to-date information there.
Looks like that there will be a check of the drill tosol.
Love it!

Grotzinger indicates SAM soil results could be a big deal; several more weeks before confident enough to release.

ADMIN NOTE: TO ALL...
Following the interview by MSL's John Grotzinger today, there has been much speculation about the nature of any future announcement.
We would remind everyone on UMSF about Rule 1.3. We appreciate that this is a very strict rule but we do expect everyone to follow it.
We may review and amend the rule at some future point, but for now it stands as is. Many thanks for your understanding.
I'm kind of looking forward to southern hemisphere winter now (solstice on Feb 15 2014). The walls of Gale were already fairly clear after landing, but just think how much more spectacular they'll look once some of this dust settles out!
It is interesting to me as degree of a dust content will affect RAD indications.
background on the strictness of the rule here:
http://www.unmannedspaceflight.com/index.php?showtopic=7514&hl=
some discussion here
http://www.unmannedspaceflight.com/index.php?showtopic=7187&st=15
Remember too that one of the main points of the npr story was that there is no announcement yet, and there may never be if the result turns out to be a glitch or whatever.
But even if it holds up, "This data is gonna be one for the history books" could mean all sorts of things. A geologist might find something very important and exciting, which the public might be utterly bored by.
Too true. Remember the hype over presidential briefing which then devolved to perchlorates? Could be anything from superoxides to carbonates. This partial leak approach is in reality a pretty poor show. Unless this is a really amazing discovery then much better to have said nothing since expectations have now been raised and disatisfaction exists where outcomes do not meet expectations.
Is this the right place for an https://hylobatidae.org/msl-panoramas/#navcam-sol102-104? Requires a WebGL-enabled browser.
(I noticed there were enough images from NAVCAM to make a rough, 360-degree view around the rover. Images are from the right-hand NAVCAM, sols 102 through 104. There's a blurry patch where I filled up a hole in the full-resolution image with pixels from a thumbnail. The ground nearest the rover on its right-hand side (left-hand side looking back) was upsampled from 512-square downsampled images. I monkeyed round with exposure a fair amount, especially to get the distant hills vaguely visible. The whole image has been shifted down manually in Photoshop, to combat Hugin's decision to put the horizon too high. I need to find a better way of fixing that. Anyway, as a first attempt with building an interactive panorama from NAVCAM images, it worked quite well!)
This is the thread, yes. Great job!
Loving the latest images to come back from Curiosity, some really fascinating-looking rocks...

As for the big announcement on Curiosity results, space.com is reporting:
"Grotzinger confirmed to SPACE.com that the news will come out at the fall meeting of the American Geophysical Union, which takes place Dec. 3-7 in San Francisco."
ADMIN NOTE: ALL, until that official announcement, this is the last comment we will permit on this subject.
Looking at the interactive pan ("NAVCAN Glenelg") posted above, does anybody know what that bulge on the horizon (looks like maybe a Toyota Prius) is, in line with the right edge of the RTG (off the tail end of the rover)? It surely looks different than the landscape surrounding it. Maybe it's part of the entry vehicle or sky crane?
(Wish I could figure out how to include a screenshot of exactly what I am looking at, without having to put it on an external website somewhere.)
If it's on the horizon, it is much bigger than any of those things. Also, on your screen cap, it's right at the boundary between two images, so it's hard to tell what it is. Try going to one of the raw image websites and find the original images. See if you can find it in both eyes of the rover. Get some 3D glasses and look at Ant103's pan. Figure out what direction the rover is facing using the shadows on the ground and the time of day (Joe Knapp's raw images page has local solar time on it). Compare it to Phil Stooke's route map and see if you can find a bump that seems like it's in a reasonable location. My prediction: it's an outcrop of rock.
It's the big lump very prominent in HiRISE images, as shown in the route map:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=28965
(upper left corner of that map).
It has been seen very prominently in every panorama since landing, from west, south and east as we passed it.
Phil
Yeah, that's what we referred to as http://www.unmannedspaceflight.com/index.php?s=&showtopic=7471&view=findpost&p=191975 way back when.
I expect the horizon to close in dramatically as we descend to 'Glenelg Destination'. Does anybody have an estimate of how many metres below our current location that is?
It will not really be claustrophobia-inducing. A few meters below our current position, five at the most, I would expect, and a wide shallow depression. I expect 'Rocky Point' will still be visible unless we happen to park close to a steep local slope.

Good! And why not to fill the sky with gray color? That there was no this black circular saw at the horizon.
Some people like to just process images as they are, some like to add fill-in skies, people like to treat the imagery differently. Why not go ahead and do a navcam mosaic with a filled in sky yourself if that's what you want to see? That's the amazing thing about all this data being out there - anyone can have a go and do their own thing with it.. That's something to be thankful for.
These blue/grey rocks toward the top of the image look like they were formed by something sticky and viscous - or maybe it's just a weird and strange erosion pattern.
http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=0107MR0682042000E1_DXXX&s=107
What are people's thoughts on the formation of Glenelg?
https://hylobatidae.org/misc/msl-curiosity-glenelg-sol-107.jpg
I have no idea as to the geological origins, but http://mars.jpl.nasa.gov/msl/multimedia/raw/?s=107&camera=MAST%5F images are up!
I've done an incredibly quick stitch just to see what's there - https://hylobatidae.org/misc/msl-curiosity-glenelg-sol-107.jpg (~9MB, ~14000 pixels across).
All kinds of differently coloured, differently shaped rocks across the landscape. Big, sharp-edged slabs, the weirdly smeary ones noted by xflare... I suspect Curiosity's going to have much work to do!
Edit: updated with better version, but still nowhere near as nice as Mr. Ant103's take below!
And my take on this mosaic. Yep, this is a great vision on Glenelg rocks, layers and outcrops. I can hear from here the metalic sound of Curiosity's wheel rolling on this floor .
http://www.db-prods.net/marsroversimages/curiosity.html#74
What can it shine if not consequences from the EDL?
http://mars.jpl.nasa.gov/msl-raw-images/msss/00107/mcam/0107MR0682028000E1_DXXX.jpg
Oh, there's going to be EDL crud *everywhere*. We can't obsess about every glint or sparkle spotted on a photo, especially when there are so many beautiful rocks and so many gorgeous windblown dust dunes stretching away in all directions. Not to mention, of course, a gorgeous, skyscraping, layered, ancient mountain over there.
However, it draws attention to itself. And if to leave without comments such objects, harmful speculation begins.
On the above pans from Ant & Cargo, we can see whitish stones on the right hand side. Very different from the rest (to my eyes)
To steal a phrase from Stu & the UK: Absolutely gob-smacking!!!
Geological question: Given that at least a portion of this area is thought to be an alluvial fan, how much small-scale compositional diversity would be expected?
I would think that the only significant sorting would be by weight, but there seem to be contrasting deposits of material (to say nothing of large rocks) randomly distributed.
Does this provide any indication as to the length of time that the purported hydrological drainage was active, or provide any other parameters/constraints? (The extremes are one-time flood or long-term flowing water).
Wowsers! Another complete HALF of the MC100 Sol107 mosaic just arrived, showing splendid detail of the entire foreground. One frame (0107MR0682055000E1_DXXX) is still AWOL but here's the rest so far...

The blocks at center right seem to be the same ubiquitously distributed material that http://mars.jpl.nasa.gov/msl-raw-images/msss/00059/mcam/0059MR0267002000E1_DXXX.jpg are made of. Almost every instance of this formation as seen in previous panoramas seems to readily split into blocks. To my eye this formation seems to overlay and form outcrops across much of the area.
My take on the geology - the alluvial fan north of the ellipse is just the last of many episodic alluvial and slump deposits that have covered the crater floor. I would think of the unconsolidated gravelly sediments we see in the cratered unit and the hilly unit as being earlier alluvial deposits, and the layered and fractured material as an older unit, either lacustrine as already suggested or maybe layers of cemented volcanic ash and/or aeolian deposits.
Phil
Phil that's exactly the overall picture I had in mind. To explain the basin I would only add one thing to your 'episodic alluvial and slump deposits'; one of two things in fact.
Either A: episodic scouring events, interleaved with and overlapped by the fan deposits
or B: emplacement of a special type of deposit more than usually susceptible to subsequent removal by sublimation and/or wind erosion.
Of course it could be C: something I haven't thought of.
About the layered rocks in the basin: I agree, not necessarily lacustrine but flat lying, well consolidated and almost certainly old.
On the way to Glenelg we passed a couple of spots where rounded pebbles were eroding out of a formation. Such as here as noted by xflare
Mastcam100 panoramic updated http://www.unmannedspaceflight.com/index.php?s=&showtopic=7535&view=findpost&p=194761.
And it's only 56° FOV
I really should have become a geologist. There's so much detail...
Nice work, all!
https://hylobatidae.org/?action=articleinfo&id=45
(I've posted my final version https://hylobatidae.org/?action=articleinfo&id=45 - two giant-sized versions to choose from. 'Huge', and 'About the same mass as Mars itself'.)
I'm sort of reminded of the textures that Spirit saw at Home Plate.
I really like the idea of these rocks being layers of alluvial fan and layers of lakebed sediments. If the atmospheric pressure varied, then when it was low, water would evaporate quickly and alluvial fan would be formed. When it was high, then water would hang around and form a lake.
I think that Glenelg may be just what it looks like. A dried up lake bed with a fairly obvious shoreline. We know that there is a river system feeding into this area so that seems like a straight forward interpretation.
Looking at the pictures of the porous, sponge like rocks I remembered I'd seen something like that before in a book on peak oil. It looks like reservoir rock, which is the sponge that holds the oil in an oil field. Good reservoir rock is often made of carbonates. Some of the rocks look to be harder and more cohesive than others, so that started me thinking about the possibilities of dolomite for the slab like stuff. And of course the conglomerate looked like earth concrete, which is just aggregate held together by calcium carbonate. The bottom line is that I like the idea of carbonates for a lot of the rocks here at Glenelg.
Thinking of Death Valley, one might wonder if there was a long period of flash floods in an otherwise dry area?
I was a little impatient in waiting for image #55 from the Sol 107 MastCam 100 pano, so I blew up the thumbnail and got it in. And I Gigapaned it if anyone is interested.
http://gigapan.com/gigapans/118975
I also got rid of most of those hot pixels in the sky.
Very cool stuff. But I'm sure you all know that!
Small preview:
According to the http://photojournal.jpl.nasa.gov/catalog/PIA16453, the site that Curiosity drove to after Rocknest (where the sol 107 panorama was taken) is called "Point Lake."
Well, this Point Lake it awesome.
Do you know if that dune that is all the way to the left is named? It's actually 3 or more if I'm not mistaken.
I suppose that the Glenelg bedrock composition would have been identified by CRISM on MRO??!
Before you go off the deep end arm-waving about Gale geology, I suggest you visit the http://www.unmannedspaceflight.com/index.php?showtopic=7375 and follow the links to resources on Gale geomorphology, geology, composition, etc. This is not a dried-up lakebed. It's an erosionally exposed surface. Also, CRISM didn't measure thermal inertia, THEMIS did. Curiosity can, and will, ground-truth orbital observations.
They are beautiful. I waited long ago this shot.

I think Curiosity may be spending awhile there...
So many features in that image to look at ! I want to be there
It is totally fine on this forum to describe things as looking like "ribs" or "sea lions" as long as you are not asserting that that is what they are! I'm curious too, it must be some trick of lighting but I can't wrap my head around the geometry.
http://astrogeology.usgs.gov/news/item/sol-112-update-on-curiosity-from-usgs-scientist-ken-herkenhoff-yellowknife-bay
Tomorrow! A short drive coming up, just a bump to put the arm down.
Phil
It's about here:
Well trick of the light? I don't know, there doesn't appear to be anywhere else in the landscape where that is replicated. Do we have anyway of figuring out the scale of this "ribbed looking" object? These are MC100 tiles aren't they?
Yeah, looks like curiosity had turkey for thanksgiving. But Spirit's high speed turtle remains my favourite.
Hey folks. I Gigapanned my take on the Sol 107 and 109 pano:
http://gigapan.com/gigapans/119035
I can spend days looking at this.
And here's a small preview:
These are fantastic mosaics! It was very good idea, to give Curiosity camera with telephoto lens.
That strange rock caught my eye too. I think of it as the "bocce ball." There sure is a lot to look at here. It's going to be very hard to pack up and tear ourselves away for the long drive south to the mountain. Even cooler rocks and grander vistas await us there!
Thank you for the links to those papers!
Ran it on the recently acquired images last night on my MacBook Pro - it's really quick. Huge thanks to Airbag for this!

Under the front bumper - Sol 111...
http://www.edtruthan.com/mars/Sol111-Front-Hazcam-Anaglyph.jpg
One feature in that image that catches my eye is the little hillock, or bump, in the upper left. It looks like its a erosional remmnant, capped by some sort of resistant unit at the top. But how would that form? It doesn't look aeolian, b/c aeolian erosion tends to create those odd inverted pyramids, since the concentration of dust/sand is highest near the ground (and the erosive power of the wind is commensurately higher). This is flattish, wider toward the bottom. It could be liquid water, I guess, but if so, this thing has survived for a long, long time without much change in morphology. If my years-old barely-remembered Colorado plateau geology is any help, maybe its freeze/thaw erosion? that would be consistent with all the jointed, ever-so-slightly displaced blocks scattered everywhere, and requires a lot less H2O than liquid erosive processes. But if it's freeze/thaw, where's the rest of that resistant unit on top of the hill?
You can see it an awful lot better in the Navcam anaglyph on page 2 of this thread. It's difficult to do geomorphology from Hazcam anaglyphs because the field of view is so limited. That hummock is just part of the edge of a much wider resistant layer that forms a major terrace all around the depression.
Phil
Interesting. But then why is the "depression" eroded? Aeolian?
Hopefully that is what Curiosity will tell us.
Phil
Just a reminder that there is a 'Geomorphology of Gale Crater' thread which was created specifically as a home for longer discussion on that topic. In part that was to avoid cluttering 'Sol X to Sol Y' progress threads such as this one. (But as always - if you want to post in 'Geomorphology' please read through the previous posts first, otherwise we will go round in circles!)

This anaglyph strains my eyes a bit. I created it by combining a Sol 102 Navcam
with an "after the bump" Sol 111 Navcam I think I got a little more 3d depth in
in the direction of what I assuming is Yellow Knife Bay. I didn't upload this anaglyph
to show off my skills, but to sneakily see if anyone agrees that Yellow Knife Bay is in
that direction.

Spot-free anaglyph of the extent to which the currently available MC34 frames from Sol 109 thus far overlay the MC100's. Judging from the copious number of matching MC34 thumbnails accompanying the MC100's all week this could get way bigger...

Atomoid, I had noticed that spot earlier and decided it looked like a cosmic ray hit to me.
Those two streaks, Phobos and Deimos? With long exposure? Or cosmic ray hits?
It all looks like cosmic ray hits and noise in those images. The sensitivity of navcam to low light levels is not good, so I expect these frames are just meant to characterize the cameras.
The brightest blobs and streaks are almost certainly cosmic rays, since they are at different positions on the two frames. Cosmic ray hits that aren't glancing, but instead come in roughly perpendicular to the CCD, should look round.
Meteors have been discussed many times in the past here, and it's overwhelmingly unlikely to catch one. Those are almost certainly all cosmic rays. The response of navcam is far too low to catch typical meteors. There were no completely unambiguous meteors recorded in all the night imaging done with pancam, which has much higher response than navcam.
Why do you say one particular blob is Phobos? There are several round blobs that appear in one frame but not the other. What's special about that one? We have no idea how long the exposure was, so we have no way of knowing how bright Phobos should appear on these images. If the exposures are long enough, it should be streaked due to its motion across the sky, not round.
I think it too big object to be a trace of a cosmic rays. If it was so, we would see such spots even in day pictures. For a moment photography there was a night and Deimos wasn't in the sky therefore I told "Phobos".
We actually do see cosmic ray hits on daytime navcam images. Look carefully and you'll find them. They're much easier to spot on the smooth sky.
But the number of cosmic ray hits you get will be proportional to the exposure time. Daytime shots typically have short exposures. Nightime shots typically longer exposures. So you expect to see more on the nighttime shots (plus they're much easier to spot against the dark background).
These are actually cosmic rays, we see a few of them, especially in long exposure shot. They can also be very bright, so bright we can confound them to meteor streaks. I am not surprised at all. And the other "blurry" dots are certainly not stars. In a long exposure, without compensation of the Mars rotation, you'd have some parrallel lines.
I don't argue, many "stars" can be cosmic rays. But I am sure Phobos is 99%
And the noise, indicates an increase in ISO, rather than exposure.
Well the easy way to determine if its Phobos or a ray hit would be to know the exact orientation of the camera, since we know where both moons are at any time. But the metadata still isn't online, so for now we can only make educated guesses.
Just in a while ago and sweet. It's an almost 360 degree view from MC34 on Sol 106 measuring a whopping 28,924 x 4399 pixels (Edit: now 29956x9599). This batch didn't show up on Joe's image browser for some reason, nor the "Raws by SOL" at the MSL site. I just happened to stumble across them in the MSL "camera specific" feed. There's a really nice view of Rocknest at the far right.

Really wonderful images, thanks to all for the computer-choking hard work...
Is Curiosity going to drill here?
I have updated the Sol 106 MC34 Pano in http://www.unmannedspaceflight.com/index.php?s=&showtopic=7535&view=findpost&p=195075 as well, preview below. My stitch seems to have picked up one of the four missing in Ant103's version, but as of now there are still at least three frames out. When they arrive, I'll update too. This new version offers superb detail of the soil and rocks in foreground and the shadows from MSL provide good scale reference. I endeavored to project it so the width to height ratio remains fairly intact for the frames toward the bottom. Kudos to the imaging team for another excellent portrait. Well done.

Sol 110 - The right side of the "slab field" from a dedicated MC34 &MC100 pairing (5213x2328px - 3MB):
http://www.edtruthan.com/mars/Sol110-Right-Side-of-Slab-Field-Anaglyph-5213x2328px.jpg
Sol 113 - Here's the left side of the slab field rendered from a makeshift pairing of a crop from the Sol 106 MC34 pano and the small MC100 pano on Sol 113. These presumably were not meant to be anaglyphed together but since the sun angle was similar I thought I'd give it a shot. It works reasonably enough to give the slab field a bit of z-axis from MSL's slightly new perspective since Rocknest (6400x2500px - 4MB):
http://www.edtruthan.com/mars/Sol113-(Mc100)-and-Sol106(MC34)-Slab-Field-Anaglyph-6400x2500px.jpg
And the "Piece de Resistance" ... much more of the MC100 Sol 107 & 109 pano in 3D. From the MC34 thumbnails in evidence, the entire Sol 107 & 109 pano will eventually be covered from foreground to foothills. This is the center slice so far - with a fantastic view of Yellowknife Bay:

Fantastic - thanks! Looks like options for getting into Yellowknife Bay may be quite limited.

Whats the link again for today news briefing ?
I found it.
http://www.ustream.tv/nasajpl2
Anyone found an archive of this yet, I missed the whole thing?
We missed a DD? How did that happen? Very faint, probably, as we might expect if there's not much dust. I hope we can track it down.
Meanwhile, from the new map just posted by Emily in the route map thread, it looks as if the 'slab field' referred to by EdTruthan a few posts earlier is the feature called Shaler.

That's so cool, Ant! Amazing that you got that together so fast after Joe made the pointing info available.
Perfectly! The first color photo of the Martian sky in a zenith? Sextant?
Pancam on both MER's took many color sequences of the sky. I'm fairly sure Pathfinder did as well.
And... it's a drive!

Where's the swear jar?
<CLINK!!!><clinkity, clink, clink, clink!!!>
I dunno what it is, but my very first impression was the edge of a dried-out creekbed!
Wow, that makes Meridiani look like the Atacama, even to my layman's eyes!
The drilling target, presumably?
The raw frames are a delight for cross-eye 3D lookers. There are a million stories in The Crater, and this is a slew of them at one stop. The panorama does seem to take in all 3 units of Glenelg quite recognizably. Won't the interepretation of these sequences be interesting?
Incredible! That picture made me shout out loud. I guess we could stop here for a bit
Can't get this to line-up properly right now, but it gives the general idea of what an *amazing* place this is. don't you think?
My bet (ok, guess...) is that this is a unit comprised of ancient aeolian deposits, sandwiched between other rock types.
Don't you just want to step on one of those protruding edges and break it off, to see the fresh broken surface? Maybe Curiosity will do that at some point.
John
It is very exciting to finally be at this stunning set of outcrops at last. Have been wanting to go straight there since it was first glimpsed two months ago from the heights above Rocknest...
http://www.edtruthan.com/mars/Sol120-Shaler-Navcam.jpg
..and a pretty quickly put together (but aligned well enough for a quick first look) anaglyph. My, it's nice to see these formations this much closer...
http://www.edtruthan.com/mars/Sol120-Shaler-Navcam-Anaglyph.jpg
These layers of Sol 120 are simply just gorgeous !
I will not post the mosaic, it was already -well- done .
But I have the full Sol 118 Navcam pan :
http://www.db-prods.net/marsroversimages/Curiosity/2012/Sol118_pano.jpg
And a color pan taken by the Mastcam34, showing a very nice scenery
http://www.db-prods.net/marsroversimages/curiosity.html#79
It would be interesting also to know what constitutes the weaker material between the resistant layers.
Maybe it was something seasonal and each resistant layer represents one Martian year.
"just like Oppy did with the gypsum vein at Cape York"
And as Spirit tried to do at King Edward, a thin ledge at Low Ridge Haven.

Sol 120 "Great Layers" pan updated
http://www.db-prods.net/marsroversimages/Curiosity/2012/Sol120_pano.jpg
Nice one! Here it is in circular format. The drive came due south and then turned SE, so I will update my map later.
Phil
I'm always amaze by the speed of delivering the picture from Mars to Earth ! This Sol 121 panorama was taken less than 3 hours ago. This is just great. A big thanks to the JPL team, and also the DSN teams

Are those the 'sea lion' rocks on the far left there?
They were straight ahead on the sol 120 pan. Now they are behind us!
Here's Ant's pan in circular form:
Nice to be rolling. I'm surprised a few more Mastcam or close-up Mahli images weren't taken at Shaler. It'd be interesting to look closely at a cross section of the rock slabs to examine their depositional structure. Perhaps there'll be a double-back later? Here's a stereo view from the Sol 121 front hazcam. The little drift in the rock depression at foreground has some interesting little mini-ripples...
http://www.edtruthan.com/mars/Sol121-Front-Hazcam-Anaglyph.jpg
...and the Sol 121 view out the rear hazcam. To my eye the rear cameras seemed to have picked up noticeably more dust since the early Rocknest images. Perhaps facing at an angle more toward the direction of the predominant east-west winds for the entire stay at Rocknest account for this?
http://www.edtruthan.com/mars/Sol121-Rear-Hazcam-Anaglyph.jpg
...and Phil, your map updates are so much appreciated... & the Sol 121 pans Ant103... nice.
Sol 109 Mastcam100 mosaic toward Yellow Knife. This sol the atmosphere opacity was pretty high.
http://www.db-prods.net/marsroversimages/curiosity.html#77
No shortage of amazing views at the moment, but backing up a bit, there was a nice Navcam 3x1 on approach to the crazy layers on sol 120.
Fascinating landscape! I particularly like this rock from the Sol 109 Mastcam100 series (cropped & tweaked from http://mars.jpl.nasa.gov/msl-raw-images/msss/00109/mcam/0109MR0685023000E1_DXXX.jpg).
Sol 122 - Taken just over 4 hours ago:

..and the anaglyph:
http://www.edtruthan.com/mars/Sol122-Navcam-Pano-Anaglyph.jpg
There's an enigmatic round formation at the center bottom, the lower half of which is just off the left channel a bit. It looks like a hollow dome - that's collapsed (really need glasses to see this). What the heck could form that?
http://www.edtruthan.com/mars/Sol122-Round-Formation.jpg
Edit: Just noticed it's in the Sol 121 Navcam shots too, from a slightly different angle...
http://www.edtruthan.com/mars/Sol121-Round-Formation.jpg
fossilised mud bubble?
Sol 122 - Front Hazcam. The "bubble" can be seen at middle left here too...
http://www.edtruthan.com/mars/Sol122-Front-Hazcam.jpg
...and a decidedly eerie looking view from the Rear Hazcam.
http://www.edtruthan.com/mars/Sol122-Rear-Hazcam.jpg
Spirit RAT hole? It snuck over here while our attention was elsewhere.
Phil
...what the hell is that thing?
My guess: There was a rock there for several (hundred?) million years, and it just gradually weathered way, leaving the divot.
It's clearly something like that, a crust that formed around a relatively softer object... but, it's the near perfect oval shape of it that makes one wonder just what that softer object was.
Here's a cross-eyed view for those without R-B glasses...
http://www.edtruthan.com/mars/Sol121-122-Round-Formation-Cross-Eye-View.jpg
A rock, obviously, or at least a clump of cohesive material. Almost looks like the remnants of same partially fill the hole.
I'm not sure anything is obvious about this feature. It is in a sedimentary deposit but was that aeolian or fluvial? Why was the raised circumference ridge more resistant than the surrounding material? Chemical influence or mechanical compression at the edge of a pothole? Teeny ejecta splat into unconsolidated sediment?
Sol 122 Navcam pan :
http://www.db-prods.net/marsroversimages/Curiosity/2012/Sol122_pano.jpg
Doing statistics with a sample of one(!) we arrived right on top of this thing by chance so there must be more of them. Have we missed some, passed at a greater distance previously? If so, maybe they can be located in existing images. If not then perhaps this is a new kind of thing peculiar to the high thermal inertia unit. If that's the case there may be more of them ahead. There is definitely scope here for a moderately outlandish hypothesis but for the moment I'm completely stumped, sorry.
If it is a relatively recent rockfall, would it fit the bill for a fresh broken surface to examine, as discussed earlier, or would the uncertainty about its age undermine any comparisons with the unbroken surfaces? It does seem to present an opportunity to compare the top surface (of the ledge) with the bottom (now top) and internal surface of the slab.
And another move, bubbles or no bubbles. This is a perspective view - near the ledge looking down into Yellowknife Bay.

Just saw those a while ago too James. Due the quantity and the consistently rounded nature of these objects it's easy to imagine the formation they're embedded was the muddy bottom of a water body, which through periodic floodings received these fluvially rounded stones, which then sank to the bottom, were covered by subsequent sedimentation, and afterward developed their encrustations by some interactive method between themselves and their substrate. That their original material was softer than their surrounding environment is clearly in evidence, so it makes sense that the heavier silts surrounding them might have easily permeated their outer skins quite easily under a bit of pressure. And of course their inherent softness would have contributed to how they became so well rounded to begin with. On the surface at least that seems to be the most terrestrially equivalent comparison. But this Mars, so anything goes...

You are so fast Phil
And my panoramic is updated with the downsampled frames (see my previous post).
The attached image happened to catch my eye today, an illustration to http://www.eurekalert.org/pub_releases/2012-12/mu-mao121012.php. I have no evidence that this is what Curiosity's seeing, but I show it because it's another kind of thing that can interrupt bedding in sediments -- not a dropstone, but a nodule that formed in place, I think. (Note that while the academic article concerns the search for evidence of microbial activity, the nodule shown here formed though an inorganic process. I think. Haven't read the article yet.)
Looks like the Martians have developed a game that combines Skee-Ball with Bowling. They must have tiny fingers though!
Thanks for keeping on top of the various occurrences of these curious features.
did everyone have one as a kid? http://t2.gstatic.com/images?q=tbn:ANd9GcRLmu14RWLE8obczOzAO6iu9rdjzeDV6tXNTcqB3KG57wQ2o2TEVw http://en.wikipedia.org/wiki/Kendama
Although the rim thickness doesn't look right, the "mud bubbles" remind me of geodes, formed by in-situ processes involving groundwater or hydrothermal fluids.
Or they could be as simple as a form of honeycomb weathering which would fit the oblongs. Perhaps chemcam will narrow the field.
They remind me, in many ways, of Pot of Gold, just more completely evacuated of the base rock (and a more complete decomposition of the indurated rind, leaving only that part protected by the proximity of the ground beneath it).
In most of the examples people have highlighted here, it looks like the base rock has been completely eroded away and the remnant rind is filled in with the same kind of soil or rock that covers the surrounding surface. However, in at least one example, it looks as if some of the base rock is still in place as crumbled-looking fragments -- that's the one that most reminds me of Pot of Gold. It also seems to be sitting up on top of the rock on which it sits and not as embedded in it as the other examples.
I'd be really interested in some ChemCam shots at something like that, where we could see if there's a difference between the base rock and the harder indurated rind.
-the other Doug
Edit -- here is the best view of the one I thought looked like it was sitting more on top of the surface, and where it looks a little like crumbles of the base rock might be sitting just inside the rind. It's the rearview mirror shot:
http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/00123/opgs/edr/rcam/RLA_408419991EDR_F0051070RHAZ00307M_.JPG
One other thought has occurred to me for the origin of these bubbles.
There seems to be a fair amount of agreement that the current surface has been deflated from previously-covering layers. We also know that Mars has a quite healthy impact flux.
Could these be remnants of small impact structures that were originally formed in a surface that has since been deflated, leaving only the small semi-spherical dyke of impact melt intact?
I admit, with a lot of these features occurring in the same surface horizon, you would have to posit a large number of relatively contemporaneous primary impacts into the now-deflated surface, and that does beg an explanation.
I've just learned that when you find any roughly circular structures on a surface that sees a significant impact flux, you need to at least consider an impact origin for them.

Another drive, perched right on the edge now. Update later.

So, Curisity has arrived at Yellowknife Bay. The Opportunity to celebrate it with a postcard, I think
http://www.db-prods.net/blog/2012/12/11/curiosity-arrive-a-yellowknife-bay/
Uh, Damien...holy crap. Wow. Other superlatives. Wow.
I really do feel like MSL is rolling on a long-dried-out riverbed from this shot. Let's see what the analyses tell us.
Looks like an inverse of Homeplate, at least from the macro perspective. A closer look will probably make this into a completely different place.
The bubbles remind me of these structures in the Navajo Sandstone:
I surmise that the science team has a good grasp on the formation and composition of the bubbles, since they did not stop for additional tests.
I guess they would do a survey first before choosing what to look at in detail.
Aaaaand, here we are ! Yellowknife Bay !

Spirit went back to Paso Robles because it would not be seen again otherwise. They were not going back that way. But we know Curiosity will climb back out of Yellowknife Bay in a few weeks, so there's lots of opportunity to look at these things again soon, and maybe Shaler as well. Right now they want to be parked and with a solid work plan over the coming holiday period.
Don't forget that we might have ChemCam data on the pits already, as we can see now that we have on Shaler. We don't know yet. If they do and it's not very interesting there may be no need to stop. The point is, they know what they are doing!
Phil
However Curiosity probably *will* retrace its steps, more or less- its ultimate goal is to the southwest, back the way we came. So it's reasonable to note things in passing, and decide whether to investigate them in more detail when we head back out.
John
[oops, overlapping reply with Phil's]
I combined the thermal inertia http://www.nasa.gov/mission_pages/msl/multimedia/pia16159.html#, CTX and http://www.unmannedspaceflight.com/index.php?s=&showtopic=7442&view=findpost&p=195644. I think it will help us to make out the geology.
Some nice sol 121 Mastcam images coming down. (A few of them seem out of focus, though.)
And at least one of the 'bubbles' has been imaged (sol 124), although only thumbnails down at the moment.
A WONDERFUL set of Mastcam34 & 100 have arrived. Can't wait tomorrow to stitch it into a mosaic (work done from my bed) !
Sol 120 beautiful layers, sharp as razor blades.
http://www.db-prods.net/marsroversimages/curiosity.html#81
And a detail at Sol 121 :
http://www.db-prods.net/marsroversimages/Curiosity/2012/Sol121_Mastcam100.jpg
To a http://mars.jpl.nasa.gov/msl/multimedia/images/?ImageID=4481 of the landing/Glenelg area and the likely route past the dunes to the base of Mt. Sharp (my green arrow approximation) I've inset Phil Stooke's route map (with a green arrow in the same direction as that in the larger map). If MSL drove toward Mt. Sharp along that green line from where it is now, it would never be more tha 100 meters from any location it has visited since sol 50. If it drove from the interesting area to the North of its current location along the blue line, it would drive past Jake Matijevic again.
Of course no one knows from where MSL will begin its trek to Mt. Sharp or the course it will take, but as has been pointed out, it is likely to to travel near to the route it has taken to Glenelg and could easily revisit a recently visited site.
And who knows what we'll see on the way to the base ... Mission planners could be wrestling as we type about this ...
The focus is a little unsharp, but there's another 'bubble' (or concretion shell?), at the top of this Sol 123 Mastcam pic (cropped & tweaked from http://mars.jpl.nasa.gov/msl-raw-images/msss/00123/mcam/0123MR0767001000E1_DXXX.jpg).

That discontinuity in the brightness of the rock in the middle Ant103's pan (around 3 o'clock in Phil's, just above the RTG); it that real or just an artifact? It looks incredibly straight.
Artifact - a frame boundary.
Phil
Yep, this is due to some gamma difference between one frame and the other. Since they've started to stretch Navcam images, you have this kind of weird effect in a panoramic.
Edit : finally, a color panoramic from the inside of the bay

Sigh...I got a worried email about Curiosity's "broken rear wheel" in http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/00125/opgs/edr/ncam/NRA_408595089EDR_D0051398NCAM00313M_.JPG. Sir, what we have here is a dirt clod. (I mention it here in case this becomes a thing and we have to debunk the broken wheel story.)
The fact that it looked the same in both the left and right navcam imagery was a dead giveaway for that.
Hey, folks. GigaPans of Sol 120 (Both MastCams).

I have to manually download each image one at a time these days. But oh well - ain't no thing. And is the raw-image site being wonky or is it just me? Images aren't showing up as they used to. Some retrieval tool sites show images first. Then sometimes, the raw-image site has the images first.
Could this (just below centre frame) be our first mastcam view of a "bubble":
http://mars.jpl.nasa.gov/msl-raw-images/msss/00109/mcam/0109MR0685077000E1_DXXX.jpg
This was from the Bell Island location, and we first noticed the "bubbles" in navcam from the 121 location, but perhaps they are still similar formations?
Looks like you're right, Fredk. That gives a good view of the 'shell' - some MAHLI images of one would be really nice now. I don't notice any on this bottom level of the depression.
Phil
Has hematite been found here in high concentrations
through any of the past observations? Looking forward to more discussion.
If these are a martian version of cannonball concretions (and that is just one of a number of possibilities) then the easily eroded interior and more resistant shell would imply a change in the accretional environment. But even if they are concretions I don't think there is any reason to attribute the cementing agent to hematite.
Sol 121 Mastcam100 mosaic now complete. But a strange effect with some of the top pictures out of focus.

Wow! Looks like some beautiful cross-bedding, especially on the outcrop in the middle.

Chemcam mosaic, sol 126 - it's getting hard to distinguish this from the MIs at Endeavour.
Phil
Good observation about the disconformity. These morphologies certainly seem to agree with this being at the tail end of an ancient alluvial fan, possibly emptying into a lake. Given the relatively small thickness of the beds and the low angle of the cross-bedding, it argues for water being the transporting fluid. This contrasts with the classical wind-driven cross bedding example on Earth, the Navajo sandstone, which you referred to in your post #259. If my memory is correct, the thickness of the cross-bedding in the Navajo sandstone is on the order of tens of meters to hundreds of meters, much larger than what we are seeing here on Mars.
We just had another move towards the rocks, probably positioning for a first test drill. Very rough position:
B-b-but ? What have you done with the sky Stu ??

Get comfy here. They said at today's Planetary Radio Live event that drilling likely won't begin until after the holidays, and that the whole process may take 1-2 months.
Some Sol 111 MastCam100 images arrived; looking back at Rocknest and tracks.

So many rocks all jumbled up together, scattered in all directions, easy to just "speed read" an image without taking any of it in. But when you isolate some of the rocks from the images, picking out those with different shapes, textures, weathering and form, it reveals what a truly fascinating place Gale Crater is, and you can't help wondering "What happened here? What made this landscape looked this way? Why does that rock look like that? What's that rock's story..?"
Not as good as Damien's work, but here is the Sol-106 Mastcam 360 pan.

Lots of arm work on sol 129. Some crazy MAHLI images coming down. Veins? (Edit: You're right, Phil; getting hard to tell this from Endeavour.)

(The raw images site seems to be struggling at the moment, so patience may be required, although these direct links should work.)
Does anyone know the status of the brush on the turrent, when it will be cleared for use? It would be interesting to use it on the above rock to see if the white veins shown are also hidden beneath the dusty areas in the MAHLI pictures that just came down.
Thanks Emily, thanks Fred, for being wellcome!
Parts of the Sol 121 Mastcam 100 images look to me pretty much like some abraded rock, almost parallel to its layering. So, very thin layers become visible.
To be able to distinguish fine details I tried to ad-hoc do some extreme false colouring of a rectangular region of Ant103's stitched image of that sol (see post #239).
The following images show, which region was chosen within the stitched image,
