I'd say that the sol 634 drive http://www.midnightplanets.com/web/MSL/image/00634/NLB_453781552EDR_F0320478NCAM00282M_.html, so it's time for a new thread! Let's see how fast they can move toward Murray Buttes now!
To release the new thread.
Although there are still some images come, first version of the navcam right on Sol 634, leaving Kimberley.

Thanks Fred! Much appreciated. PS: nice hat.

Here I have 'borrowed' jmknapp's nice topo map (posted in the route maps) and merged it with a CTX image. The red and orange hills at lower right are in the big dune field. This shows nicely that we have 1 km or so of driving across the depression we're in now, and then it will be uphill most of the time. The dunes are not in the lowest part of the crater, they are wrapped around the lower slopes of the hill.
Our current position is in the top right corner. Incidentally, we are about to move into the next map quadrangle, with a different source of names. We already crossed into it very briefly and then back into the Kimberley quad shortly before arriving at Kimberley.

The large rock in the middle of http://www.midnightplanets.com/web/MSL/image/00635/0635ML0026970000302690E01_DXXX.html seems a bit out of place. From this distance, its surface texture reminds me of the pits on a meteorite. Since we're moving more or less in that direction, maybe we'll get a better view later.

That big rock does look enticing! I think we'll go pretty close to it.
Phil
Random note: a few weeks ago I learned that the DAN pulsing neutron generator had a limited lifetime. Today someone pointed out the arithmetic to me: the warranted lifetime for DAN was 3 years after launch, or until December 2013. So any day that DAN's active mode continues to work is a blessing. Similar units on Earth have lasted anywhere from 2 to 6 years, so it could continue to work for a while, but may not. It should function forever in passive mode, and still do great science searching for anomalous levels of hydrogen in the subsurface, but once the neutron generator dies (and apparently once it goes, it goes quickly) it will no longer be able to suss out the layered structure of the subsurface.

Nice!! Joe, what do you estimate the size of that rock/meteorite? Fred, we need someone standing next to it!
Part of the Sol 637 Navcam panorama in Stereo.
Jan van Driel
Here's a quick job, using Phil's map to estimate 11.6 and 35 metres to the two large rocks:
Floyd: roughly I get that the rock is 14.5 meters away and covers an angle of about 8.1 degrees in the NAVCAM frame. That would make it about 2 meters across at the base.
EDIT: I got the distance estimate using 38 pixels of shift in position between NAVCAM L and R, baseline of .414m: d=(.414/2)/tan(45.33/1024*38/2) -- Fred's estimate using the map could be closer, who knows.
At this stage my position is only accurate to within a few meters, I don't make any claims beyond that.
Here's a circular pan from jvandriel's postings.
Thank you Fred and Joe! Like Phil, I certainly hope we head south for a scientific diversion to examine these rocks.
ChemCam had a http://www.midnightplanets.com/web/MSL/image/00637/CR0_454037573EDR_F0321020CCAM02637M_.html at the "big rock" (lower part of the image).
Looks more and more like a meteorite to me.
Looks like another iron, but I'm hoping it's a chondrite. It must weigh several tons, even on Mars.

Is there a compelling scientific reason for MSL to analyze an iron-nickel meteor further (drive over there, etc)?
Sol 637 mastcam 100 view of the two "rocks":
The bumps aren't spurious (I don't think); typical http://www.midnightplanets.com/web/MSL/sol/00640.html (see bottom of page).
Gorgeous (and probably practical in some way?) http://www.midnightplanets.com/web/MSL/image/00640/0640MH0002610010203791E01_DXXX.html.
The short bumps are not spurious, they are doing wheel imaging with small rotations between images.
Checking whether these rocks are meteorites is a worthy goal - not enough for a long stop, but I would suggest it would be useful to get ChemCam LIBS data on them to compare with APXS which we have for the Meridiani meteorites. As for clustering, Spirit also say 2 or possibly 3 meteorites at Low Ridge Haven, and at Meridiani Shelter Island and Mackinac Island were also close together. Atmospheric breakup seems quite likely.
Phil

636:
Hopefully ChemCam got some good distance zaps in, because that rock (meteorite for sure?) is now far in the rear-view mirror!
(just thumbnails for now)
I've been surprised by how far west we've headed - I guess that way lies flatter ground for longer drives. And softer ground - because unlike Opportunity's solar arrays, the wheels aren't getting any better
Looks like 42m to the northwest--Murray Buttes beckons?

And we get a name from Fred Calef's latest map at JPL - Lebanon is the closer meterorite.
And I think this is the first name from a new map quadrangle.
Phil
Indeed, Fred said on Twitter we went into a new quad "on sol 636. The quad name is 'Hanover' after the New Hampshire city. The mapper of that quad went to Dartmouth."
Quads: I've dug down and found out about the demarcation of the quads, the reason for their strange non-metric dimensions, the names of ones passed through and so forth - but it wasn't easy. I think a lot of followers here would appreciate a refresher on that topic if anyone's up for it.
I've been asking for a map with the quad names on it for a long time but have not been able to get one. (If it is, in fact, on the Internet somewhere and I don't know about it -- I hope someone will point it out to me). The best explainer on the quad mapping thing is http://www.lpi.usra.edu/meetings/lpsc2013/pdf/2511.pdf (PDF).
I feel that it would be a mistake to use the "Block Island Trio" for want of a better description as a template. The weathering of these examples at Gale seems more akin to Heat Shield Rock. The remnant coating on the Meridiani Trio could simply indicate that the abrasive scouring was reduced dramatically to an extremely gentle caressing before the process of removing the coating was completed. I think we can be certain that the Meridiani examples were subject to a very acidic environment although if the impact occurred early enough they could have encountered higher pH, basalt buffered groundwater. For Gale however it seems that the environment at this level was consistently pretty much neutral and could well have been reducing. As far as time lines go we do not really have a clue whether the Gale examples impacted early on as the sediment in the crater was building up in a saturated environment or later during the dry, deflationary period. All is conjecture anyway as these rocks diminish in the rear view mirror.
OK guys, when was the last time Curiosity used AutoNav? Was it before they started worrying about wheel wear?? http://www.midnightplanets.com/web/MSL/sol/00643.html suggest the rover was driving for itself...
This is a quick guess at the new location. If it's right we are probably over the 7 km drive mark now.
Phil
That's pretty much the spot--85 meters: http://curiosityrover.com/tracking/drivetrack.php?drivenum=186
Emily: I think the last time hazcams were mixed with navcams like that was on April 20, http://curiosityrover.com/tracking/drivetrack.php?drivenum=175. They were looking at the wheels a lot during that drive. Before that, March 18, http://www.midnightplanets.com/web/MSL/sol/00574.html.

Is it my imagination or are the erosional patterns and structure of the two apparent meteorites in Neo56's context image sufficiently different as to raise the small possibility that these are the products of separate impacts? Be one heck of a coincidence of course.
A good drive today, already past the two small craters. A proper map update tomorrow (I'm in restricted sols)

Fantastic, Damia!
This is my enhancement of your mosaic with an insert showing this guy (4.5 km wide and 30 km distant) with same orientation.
Great view of the crater... looks like we will be able to monitor the slopes for dust avalanches or other features! Seriously - it might be worth occasionally looking back at the main crater rim and smaller features like this crater to check for changes.
Meanwhile, this is a quick look at where we are - took me a while to figure out the location but I have put up a new map as well.
Phil
Phil, how about a hint of how far we drove? West or southwest???
That's on the map! - but you're right, I could mention it here. I will try to remember in future. This time, about 34 m WNW.
Phil
I have just become aware - a bit late - that the big dune field around the flank of Mt. Sharp has been given a name: Bagnold Dune Field. It's named after a person who wrote a very influential book about dunes. The name has appeared in three places so far - an LPSC abstract, an 8th Mars Conference abstract, and a paper in press in JGR Planets by Arvidson et al.

There is a very prominent mesa at the west end of the visible flank of Mt. Sharp, some distance beyond the current target area. I found what I think are the first and latest MastCam-100 images of it to see how much our view had changed. Not as much as I expected really! - partly because we are driving directly towards it, partly because it is beyond our goal so we are not all that much closer to it, proportionally. It did make me think that there would be some other interesting comparisons to make like this.
Phil
Cool comparison, and I'm surprised how little it's changed, too! I wish we had some names for these prominent features. I asked Grotzinger the other day if they had a name for the valley with the inverted channel in it, and he said no but "we really oughtta name that." I'll see if I can give them a gentle nudge from time to time.
Ah, but is it a deposit of conglomerates, or of breccia? They look rather similar, and each has about an equal chance of showing up here in Gale.
-the other Doug (with my shield, not yet upon it)
That identification agrees with Emily's from 2012, where she also identifies several other features:

I'm a little surprised that no one has commented on the MARDI drive video yet.
http://mars.jpl.nasa.gov/msl/multimedia/raw/?s=651&camera=MARDI
Yes, we know it's overexposed.
The exposure time was set by autoexposure when the camera was looking into shadow, and then the drive put us in a much brighter illumination geometry. Next time we'll probably use a pre-calculated manual exposure.
Quick playaround with the MARDI images to improve the view.
Gamma stretched, strained the colour etc...
http://youtu.be/Kd81xvgYx30
It will be nice to see the larger files if they come down.
Certainly the next time will be better with lessons learned as Mike pointed out
Having looked at the great animations above I thought I would have a go myself.
To that end I put together some ChemCam images from sol654, they show ripples propogating from the centre of the target. I assume that's dust being moved by heat, or vibration.
Nice. I guess each frame follows another blast from the laser.
These frames were taken over a span of several minutes. I didn't think chemcam had video capability.
When it's firing the laser, the spectrometer of ChemCam is collecting data for the spectra - not sure if it could image at the same time. I would expect it's a few seconds between frames in any case.
D
There was a sequence of images on 283 that suggest simultaneous laser firing and imaging:
http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/00283/opgs/edr/ccam/CR0_422611899EDR_F0060082CCAM02283M_.JPG
Sadly, that's not the ChemCam laser, at least not in the way you're thinking. Mike Howard tweeted about that image back when it was taken, and Ryan Anderson replied "This isn't ChemCam laser firing. It's alignment laser. Vertical line not laser, just overexposure." I'm not actually sure I understand the distinction myself. I haven't written the book section on ChemCam yet.
Edit: Mike: jinx!
Definitely the vertical streak extending below the bright spot is not a laser beam, since the beam would be coaxial with the optical axis. It doesn't really look like CCD bleeding, but must be some related effect.
According to http://link.springer.com/article/10.1007/s11214-012-9912-2 there are two lasers - LIBS is the main laser, and there's also a lower power continuous wave (CW) laser used for autofocus. Both beams are coaxial with the optics. That paper states that "the [LIBS] spark itself cannot be observed". But apparently the autofocus spot can be. Fig 64 in the paper shows that the CW beam spot has a size, shape, and orientation matching well the spot in the image I linked to above. So it looks like they imaged the autofocus laser spot, perhaps to check the alignment.

I think we are seeing the two (already highlighted) circular features in the central frame, probably Curiosity will visit them in next days...
A quick guess as to our location on sol 655. I will update the map later. (EDIT - I changed the attached file and corrected the location)
Phil
According to https://twitter.com/Matt_Heverly/status/476343275683454976, Curiosity just passed the 7 km mark. Joe's drive log has us over 300 m past that. It's hard to reconcile everything, but I guess I have to go with the project.
Phil
Hmm. Might that number correct for slip?
Yes, that's what is going on, we always have this conflict between numbers.
Phil
Following on from my previous post (#156), am I to conclude that this is a sequence of shots from an 'autofocus assist' laser?
The other question I had was that if the images were captured minutes apart, why does the ripple effect appear the way it does?
Were they taken minutes apart or just received/uploaded minutes apart?
Yeah, from what I read the CW laser is used for autofocus. The laser fires and the secondary is stepped through some range of travel, while the returned intensity is monitored. I think the maximum intensity corresponds to the in-focus position. But someone may correct me/elaborate on this. Normally the CW laser is used for focusing but no images are taken/returned while it is running. But it looks like they decided to do that on that sol, maybe to check the alignment of the CW laser.
I assume each firing of the main laser blasts the dust farther out. When the images are combined into an animation it looks like a smooth outwards ripple-like motion, but in reality it happens in short bursts with each main laser pulse.
I think the timestamps correspond to the time the images were taken.

Thanks for digging that up, Gerald. I guess they wanted to test the alignment over a range of target distances.
Trying to keep speculation here rather than Map Thread, it seems http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=32803is not northern enough. We are now northwest of where the yellow route turned south to join the green provisional route. Does it now look like we will not be joining the green route any time soon, but rather loosely paralleling it 200-300 m to the north?
Marco, maybe you could do a new look ahead from where we are now.

I had my weekly call with Ashwin today but there's not much news -- obviously, they're driving. I'm not sure if I'm going to write up a blog post tomorrow or not. I'd wait for a week, but, looking ahead, the prime mission is coming to an end at the end of sol 668, which is on June 23, so I expect there'll be some hoopla around that time about what's been accomplished. It also marks the end of the period that my book is supposed to cover, after which I am supposed to "wrap things up." Yikes. (I think I'll actually cover more than that with respect to traverse, but not with respect to science.)

It seems that the two circular features that we bypassed on Sol 657 are craters that are filled with lithified sediment. Obviously Curiosity's schedule did not permit a closer look although these features could possibly have provided a useful data point for this area. In order to be filled with lithified sediment these craters must have been formed during the early depositional period and been exposed, then or subsequently, to a wet environment. The degree of cementation and compaction would provide some indication of the depth of material deposited above this level. But then again, I guess the same data was gathered at the Kimberley.

Right! I didn't have the route information, I just drew it as a straight line. Now I can fix that on the map. Curiosity's windshield must be covered in bugsplat after that drive.

Since neither path has ever been taken, which one would you choose?
Looking farther ahead, I wonder if there's been any thought about trying to drive on the dark dune sands. They would likely be very easy on the wheels and the total distance (and time) driven could be substantially shorter than the "rapid transit" route.
Of course the worry would be getting stuck Purgatory- or Troy-like. But the properties of the dunes here may be quite different from those we've seen before. We'd need a toe-dip to know for sure what the grain size and properties are.
Still I can see problems. The properties of the sand/dust may vary, and what looks safe at first may turn nasty out where the dunes are dangerously deep. And if a toe-dip showed a bad driving surface, we might be in a worse position to have to make our way back towards Murray Buttes than if we had continued near the rapid transit route.
Topo map, sol 636, 1m contour interval, all scales in m:
Cool. Wow, that topo map really puts the regional landscape in perspective. Looks like we're steering around that highland, but we can't do it forever -- there are dunes in the way. What's the baseline for the slope map?
Thanks for the info. Here's a map using your colors and a simplistic slope calculation (yellow dot at current rover position):
We skipped through the pass overnight... but not much to go on yet:
It looks like we are now perched on the edge of a depression, with highish slopes visible in Joe's new slope map. It'll be interesting to see if we pluck our way around it or plunge straight through after analysing the new images.
About the directionality of slope, the slope of a smooth (or smoothed) surface is represented by a vector, so in principle there is more information to plot than a single number at each pixel. But in practice, I would doubt it would matter to the drivers whether a too-steep slope is directed along our direction of travel or orthogonal to it - it would still represent a slipping hazard.
Maybe the most useful thing to calculate would be the maximum slope over all 360 degrees of angles. But in practice that might involve fitting over more than 3x3 pixels and hence loosing some resolution. I'm sure the drivers chose the simple rms x-y estimate for good reason.
Edit: whoops: the maximum slope is just the magnitude of the gradient vector, which is just the rms x-y estimate that Paolo mentioned. No need to explicitly maximize over angles. But when it comes to pixelization things can get trickier as you have to choose how many pixels to use and how to calculate the slopes. And the existence of the gradient vector assumes a locally flat surface, which may not hold well at the level of the pixels.

I superimposed Joe's topo map on yesterday's route map for a close-up look at the area. This doesn't include the 664 drive.
Phil
I'm thinking we may stay on a northern route and go almost due west for about 800 m. While it is not all valley sand, there is a fair amount of smooth terrain. Or the Other Road is due south.

Jan's pan in circular form. It looks like we bypassed that nice outcrop, probably on its south side, maybe with some mid-drive imaging that hasn't come down yet, and we are now adjacent to the rocky hill SW of the outcrop. A drive of about 140 m, I'm guessing, SW and then nearly west.
EDIT - no, it looks like we passed it on the north side and drove southwards to our current location, now we have more images.

Nice--and no doubt easy on the wheels. Interesting how much darker the soil gets when disturbed.
I'm currently still confused on how long until the probe gets to the opening at Mount Sharp? I know there isn't any definate time frame. Is there isn't any updates at the MSL site on this.
It looks like they are going all out now to get there quickly - let's guess the end of the year, though. December at Murray Buttes, that's my guess. That might permit a short stop at Waypoint 4.
Phil
The preliminary objective is the entrance would that be fairly soon, I'm not talking deep into the crator area of mount sharp.
Mount Sharp is quite a broad area.
I view the Raw images every day, I'm tired of waiting. Less than two years into the mission. I'm very eager on the results. Unfortunately the board rules don't permit any of us to discuss on perspective, context etc
ADMIN NOTE: One thing that members have learned is that taking the tone of "Are we there yet?" is not a 'contribution' to the Forum.
The Board Rules do in fact permit discussion on 'perspective and context' when there is a perspective to be had and context to be drawn based on available/reliable information. Impatience with the progress of a mission contains neither.
Ground progress to date, crow-fly distance to Murray Buttes, m:
Really accelerated recently.
I've just noticed Ken's blog on USGS is up and running again and soon to have a couple more contributors:
http://astrogeology.usgs.gov/news/astrogeology/sol-662-update-on-curiosity-from-usgs-scientist-ken-herkenhoff-resuming-msl-blog
Tosol 668 should be the end of MSL prime mission.
Except a few private tweets I didn't noticed anything about this fact on NASA, JPL, MSL or other related web pages.
Some celebration, our rover has survived, 7.95 km on odometer and still roving, all instruments in good shape, etc, mission extension confirmed till ... end of life.
Did I miss or overlooked something? If yes I deeply apologize.
Originally, the primary mission was said to last for one Mars year, and as you say it should be ending now. But more recently ( and I mean since landing, not just the last few months) I have seen that extended to the end of 2014. Maybe this was to increase the likelihood that they would arrive at the destination during the primary mission.
Unfortunately, right now I can't find one of those statements about the length of the mission.
Phil
Thank you Phil for the explanation. Despite I'm almost daily follower of this mission such info somehow passed by without me paying attention.
Also MSL homepage was not updated yet, still mentioning "Length of mission on Mars: The prime mission will last one Mars year or about 23 Earth months."
http://mars.jpl.nasa.gov/msl/mission/rover/ or http://mars.jpl.nasa.gov/msl/mission/timeline/surfaceops/
The extended mission begins on sol 670 as far as I know.
http://starbrite.jpl.nasa.gov/pds/viewMissionProfile.jsp?MISSION_NAME=MARS%20SCIENCE%20LABORATORY
Got it - this was what I was thinking of:
"MSL's primary mission spans one Mars year (669 sols or 687 Earth days) after touchdown. Science team activities would terminate six months after the end of the surface mission, whether it ends after one Mars year or after any number of extensions. "
- that's from http://msl-scicorner.jpl.nasa.gov/scienceplanning/
- and I had seen a presentation (possibly Jim Green at LPSC, but not sure) which referred to the end of the six month science team operations after the first Mars year. But that is the primary mission plus analysis time, so I was wrong to refer to it all as the primary mission.
Phil
What a beautiful little dune at the end of the 2h+ Sol 668 drive!

Edit: Anaglyph:
http://imgur.com/Tn09Abx
Here is most of the "safe transit route" dropped in to my most recent 3D map. The route path is only in the green and blue channels (I didn't want to take time to coregister it with red). It's a southerly drive across pretty nondescript terrain for about another 700m, and then they'll drop over a little ledge that takes them into more canyon-style country with sand-rippled canyon floors. That's going to be pretty cool looking, I think! We'll be much closer to the dune fields by then but I'm not sure how well we'll see them from the position down in the valleys.
Looking at the bigger map, it almost looks like there's a shortcut due south of the large filled in crater we're approaching. Presumably the goal is to do science at Buttes themselves, and it would just be more backtracking from Mt Sharp to go that way?
Love the cross-eyed images, and very happy the USGS blog is back!

Definitely bringing back memories of Oppy's Great Trek.
I brought up the question of driving on the large black dune fields recently. As we head south and then enter the valleys it looks like we may see so many smaller dunes like this that we may end up with a big benefit to the wheels due to the soft surfaces without having to drive on the big black dune fields.

Saw the raw images from sol 672, they made me do a double take as one of the wheels in the forward hazcam was slightly buried in sand (not like Opportunity at Purgatory though) and it appears the other wheel is still completely on the surface. I take it they're not stuck.
No, not stuck at all. About 80 m slightly east of south today. (oops, just saw Damia's new pan. I will do a better circular pan from it if we get the last bit filled in soon)
Phil
The http://www.midnightplanets.com/web/MSL/image/00672/NLB_457153056EDR_F0380000NCAM00354M_.html, so it really looks to me like the wheels were slipping. I went out on a limb on Twitter and guessed that the drive aborted due to excessive slip. Mostly I did that in the hopes that I'd be proven wrong! I looked hard at the wheels and saw a little sinkage but nothing that they shouldn't be able to back right out of if they decide that's what they need to do.
...Or the drive ended where it did because that's where it was supposed to end, and Curiosity will drive right on out of there with no problem. I don't know. Either way, they're not stuck. If there's one thing Curiosity has learned from Spirit and Opportunity, it's how not to get embedded in sand.
We've the Sol 672 http://mars.jpl.nasa.gov/msl-raw-images/msss/00672/mhli/0672MH0003250050203899I01_DXXX.jpg, and http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/00672/opgs/edr/ccam/CR0_457156102EDR_F0380000CCAM15028M_.JPG. Looks more like a regular stop. Otherwise I'd presume, that the flight software would have stopped all follow-up activities, until a potential issue would have been solved manually.

Not sure if it represents real data, but going by the http://curiosityrover.com/tracking/speedplot.php?drivenum=205 of the recent drive, it's consistent perhaps with a wheel slipping. Spikes like that have occurred http://curiosityrover.com/tracking/speedplot.php?drivenum=196, maybe it's a slip signature.
EDIT: here's some data from the end of the drive, just the time stamp (seconds from the start of the drive) and the average speed (cm/s) since the last time stamp (usually 1 second):
Emily has an enviable ability to summarise Curiosity's endeavours in clear and concise English.

Of particular interest to me was the ChemCam finding on the circular feature just in front of Dingo Gap. "One of the highest hydrogen signals of any rocks observed to date." The other circular features encountered were attributed to gas bubbles and I have always held doubts on that score. No matter how I squint and look sideways at them, many still look like the remnants (or at times complete) diapirs to me. Less dense, liquidised sediment rising through an overlying deposit of mud. The high hydrogen reading would be a tick in the box in favour of that hypothesis although Munroes would also be a another possibility.
Edit: (Extract from Journal of Sedimentary Petrology Vol. 43 (1973) Page 848 "Small mud mounds, here called monroes, occur in tidal flats of the St. Lawrence Estuary, Quebec, Canada. They occur generally in groups, and occasionally in isolation in relatively soft mud, have a rounded conical shape with occasionally a nipple at the top, steep slopes (40° to 65°), and are 5 to 25 cm in diameter, and 5 to 20 cm high. They characterize mud tidal flats of cold regions").
