OK, we have left the dunes, and it's time for a new chapter in our story as we head south to Vera Rubin (formerly known as Hematite) Ridge.

Mission Update from Ryan Anderson: https://astrogeology.usgs.gov/news/astrogeology/sols-1661-1663-dan-has-been-busy
Once the remote sensing is done, MAHLI will take some pictures of the targets “Paradise Hill” and “Treasure Island”. APXS will then analyze both targets, with an overnight analysis of Treasure Island. On Sol 1662 we will drive again, followed by an autonomously targeted ChemCam observation, and on sol 1663 Curiosity will have a pretty easy day, with some Mastcam atmospheric dust measurements and a MARDI image of the ground beneath the rover.
Throughout this week, the environmental science group has been working to recover the activities that were lost last weekend because of the Deep Space Network outage, such as the morning imaging suite and 15-frame Navcam dust devil movie, while also continuing the normal cadence of monitoring activities. Earlier in the week, a special DAN active measurement was acquired over the sand of “Ogunquit Beach”. By turning the rover in place and backing up onto the dune, we placed the field of view of DAN's active neutron experiment, which is centered between the rear two wheels, right on the dune sand. DAN active experiments are performed after each rover position change (usually immediately after a drive), but in this case, the measurement was taken just before the rover departed Ogunquit Beach. In a DAN active measurement, neutrons are fired in all directions by the Pulse Neutron Generator, and some neutrons scattered by the soil under the rover return to the DAN detectors. This measurement will allow DAN to compare the amount of hydrogen measured at Namib Dune around sol 1243 to the conditions at Ogunquit Beach.

DD activity has been quiet recently, but here's a large (or close) DD on 1660:

It moved right to left (note the negative image). I think it's behind the distant knob, which would make it very big.

Curiosity Rover Mission Update: https://astrogeology.usgs.gov/news/astrogeology/sols-1664-1665-keep-on-driving
Planning is restricted this week, so two sols were planned today. Untargeted remote sensing planned for Sol 1665 includes passive (no laser) ChemCam sky observations and two ground LIBS targets selected using the AEGIS software. Navcam will then search for dust devils and clouds before the rover rests in preparation for Wednesday's plan.

I found the pointing for the RMI's (169.48° to 171.78°), but would like to calculate the approximate height of the cliff face and or the width of the terrain covered by the mosaic. Google Earth (Pro) does not have high res map coverage in that section of the mountain, or I could have used their measuring tool for a rough guide based on the bearing. At that long range AlgorimancerPG would likely be of little use, even if I had the stereo pair to go with the frame below?
Does anyone have an idea of the distance to the target? Or has someone already worked out the scale for this mosaic? TIA

Posted by: elakdawalla Apr 12 2017, 04:34 AM
I don't have time to do this myself, but: take the CTX mosaic of the Curiosity landing site, crop it so that Curiosity's current position is at the center, use Photoshop polar > rectangular filter to "unwrap" the horizon, stretch or shrink it vertically as needed to make the horizon legible, and compare it to a Navcam panorama to locate the peaks. (If you don't use PShop I'd be shocked if GIMP didn't have a similar filter.)
Posted by: PaulH51 Apr 12 2017, 05:39 AM
Thanks Emily, I look at that process....
Meanwhile Curi has driven as planned, no distance data yet but we have a few end of drive NavCam frames, I will stitch what I can soon.
Here is a RMI mosaic acquired before the drive to Site 62/0690 of what I believe to be The 'Exposure of Bedding dubbed 'Great Wass Island' mentioned in the recent USGS update. The pointing is currently shown as above the horizon so I cant accurately locate on the NavCams, nor scale it at the moment, but likely close to the rover.

USGS Mission Update by Ryan Anderson https://astrogeology.usgs.gov/news/astrogeology/sols-1668-1670-diving-into-analysis-of-moosehead-lake
On Sol 1669, we’ll retract the arm and drive, followed by post-drive imaging and a MARDI observation in the evening. On Sol 1670, there is a short morning block of atmospheric observations and a longer afternoon block containing a Mastcam image of the rover deck, another dust devil observation, and an auto-targeted ChemCam observation. We will wrap up Sol 1670 with some observations of the dust in the atmosphere to compare with the morning.
Speaking of atmospheric observations, let’s do a recap of the environmental science we’ve done this week. Of course Curiosity acquired the usual REMS and DAN measurements as well as Navcam cloud observation movies throughout the week. The pointing direction of the cloud movies was shifted from north-facing to south-facing to avoid the sun. The movies will remain pointed towards the south until just after the southern hemisphere spring equinox in May 2018. As mentioned above, there was a Navcam dust devil survey on Sol 1670, as well as one earlier in the week on sol 1668. Also captured earlier this week in ENV planning was a ChemCam passive sky observation on sol 1665 that had been previously dropped twice from the plan due to the DSN outage two weeks ago and sun safety issues last week. Planning passive sky observations is difficult: they are among the most time consuming and time constrained atmospheric observations. This is because the observation requires ChemCam to take passive spectra of the sky at two different azimuths and ChemCam must avoid the sun’s path as it slews between those locations. This can be difficult near equinoxes when the sun passes directly overhead!

Sand crepes. It looks like the delicates crepe is placed on top of a layer of sand. In the image above, are the sandy areas -- low spots that accumulated sand, or are they -- high spots where the crepe has eroded and exposed sand?

There's been a change in the ownership of the blog. Ashwin told me: "FYI we have changed our blogging from the USGS to JPL. The original 3 authors still participate, but we’ve recruited several more. The posts are now natively hosted at JPL (same web page) instead of mirroring USGS."

If those are focus stacks, that's the kind of thing you expect since the process combines parts of the various images with the best focus. The original images shouldn't show those effects.

That's no MAHLI pin chevron! Those are ChemCam pits in sand, made the day before:

For the focus-stacked images, the motor count for the first image may be well off-focus. In this case, the motor count of the first image of https://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=1691MH0001630000603960R00_DXXX&s=1691 is 13722, while it is 13916 for https://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=1691MH0001520010603898C00_DXXX&s=1691.
Whenever the scale is essential for an investigation, I'd recommend to work with single unstacked images, and apply the scale to the sharpest areas.

I'm not sure what we're seeing in these two 1694 navcam frames taken about 30 seconds apart:
|
You can see that the most distant slopes brighten relative to the foreground (note that exposure differences may make it hard to know if the slope brightened or the foreground dimmed (or both)).
One guess is gust activity, although it's been very quiet recently and this looks awfully uniform.
A better guess might be a Phobos transit, but I haven't checked whether that happened at that time...
Posted by: serpens May 23 2017, 11:28 PM
I wonder whether they select different exposure times for sequential shots to compensate for under/over exposure risk?
Posted by: PaulH51 May 24 2017, 04:56 AM
Sol 1705: 11 L-NavCam cropped pan. The time stamps on the frame suggest a drive duration of ~35 minutes. Edit MP report the drive as ~6.8m SSE

Posted by: djellison May 24 2017, 03:17 PM
So it's exceptionally rare to manually set exposure times for Navcam/Hazcam. In 29 sols of MSL ECAM planning I've delivered 224 sequences that have taken a total of 1369 images...and I've never done it.
What happens is that it starts with an average seeded exposure time - and if there's not enough photons on it ( or too many ) it alters the exposure time and tries again. It's rare for it to take more than one or two iterations to get it right. Then, every image taken after that, until the rover goes for a nap, starts with the previous exposure time as its seed. Typically - that means it takes one or two goes to get the first frame, and the rest run off without having to refine it - especially with sequences like this that are pointing the same. There's also the fact we've got 12 bits of depth - so even a poorly exposed image (due to rover parts / glinting / sun in frame etc ) can typically be stretched into usefulness.
Sadly - when the raw JPGs are stretched, and from EDRs not RADs, then it's hard to see what's going on in this particular instance - but there's definitely something going on.
Posted by: mcaplinger May 24 2017, 03:50 PM
As an aside, also true for Mastcam/MAHLI/MARDI, which inherit their autoexposure algorithms from Navcam. I've been surprised at how few manual exposures there have been.
Posted by: djellison May 24 2017, 05:00 PM
Once you've gone Maki - you can't go back.
Posted by: fredk May 24 2017, 05:06 PM
Back to the 1694 navcam sequence, here's the difference between the first and second frames:
|
You can see how the most distant slope was darker compared to the foreground in the first frame. (Again, we can only make relative statements with these public jpegs.)
A Phobos transit with a path to our south might explain this. Or an extremely large and extremely uniform gust.
Posted by: Deimos May 24 2017, 05:14 PM
According to the ephemeris, the shadow of Phobos passed to the south of the rover and over the mound at this time. I don't see anything that is obviously dust activity in the wake of the (very small) thermal effects of the shadow.
Posted by: fredk May 24 2017, 06:38 PM
Thanks, Deimos. This is the second time that I know of that the penumbra of Phobos was imaged by MSL, after sol 368 when it was imaged with hazcam.

The notional routes appear to be more like guidelines, the real path has often deviated from them. Nevertheless, two of the most recently proposed ones seem to coincide on the ascent point. Perhaps there aren't many options. We'll see. Less than 800m now.

Now that all the navcams from that 1694 sequence are in here's an animation of all frames showing the penumbra. (The remaining frames show no differences above noise.) I've done a multiplicative rescaling of the overall intensities of the first frames so that the foreground brightnesses match, on the assumption that MSL was outside the penumbra. (It's worth stressing that this isn't proper calibration, just an ad hoc correction for exposure variation.)
|
We can see the penumbra slip away. The dark highlights on some rocks in the first frame are probably due to specularish reflections of the darkened sky.

Concretions?

Raindrop casts.

Raindrop casts would be cool, but I'm betting on concretions/groundwater cementation. Consider this terrestrial example:

As dburt notes, probably concretions. The reasons I queried rip up clasts were the number of non spherical clasts, which is not common for concretions and the "jumbled" appearance of the matrix which could represent a sediment rich flow or slurry off Mount Sharp.

Thanks, Jan. Here is a circular view of your panorama. It seems a long time that we have been crossing this landscape of scattered blocks, but soon I think the landscape is going to look very different.

It would sure be great if one every week or two they added 8 images above the current Navcam set so we could see where we are going

That's called doing an Upper Tier.....we try to convince the science team to let us (ECAM) do it quite often....but realistically we only get to do it when they need it for targeting other imaging. Fear not.... first stop on the VRR imaging campaign is coming up in a few more drives and we'll be doing one then.
(Edit... as if by MAGIC... https://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NLB_550725914EDR_S0640000NCAM00288M_&s=1726 )

Well that Upper Tier was nicely timed The VRR is a thing of beauty...

Doug & PaulH51,
Many thanks as always. It is nice to see Vera Rubin Ridge.

And an anaglyph of Vera Rubin Ridge from the pancam photos of 1726.
