It's not easy to figure out where to divide threads, but we just had a drive on sol 72 which I think we could say signifies the beginning of the traverse to the south and the start of regular science operations. Originally I expected a clean break with helicopter operations but we are not getting such an obvious dividing point.
So I am taking it on myself to start a new thread for the exploration mission. If the timing seems wrong people can let me know.

Here is my version for the Sol-72 Post-drive panorama. I kind of went your way Phil in projecting the polar, or what you say is called 'Circular'. Let me know if you want me to do these in the future over the previous polar projection that I used.

That's very nice, James. If you feel like doing that I would be happy to see it.
It looks to me like there is a nice path to the SSW from here to a smooth area which would be the next helicopter landing zone.

No sign of any skyglow in those images - the ND mask should make that easy if it was there. Insight ICC, which is optically identical to skycam, was able to see some skyglow at night back at http://www.unmannedspaceflight.com/index.php?showtopic=8432&st=780&p=246294&#entry246294 which we speculated was due to Phobos-shine. Perhaps it's just a matter of exposure time.

ICC also http://www.unmannedspaceflight.com/index.php?showtopic=8432&st=720&p=245855&#entry245855 on several occasions, so skycam should be able to too, and the https://www.hou.usra.edu/meetings/lpsc2020/pdf/2282.pdf was to measure stellar fluxes at night.

Posted by: Andreas Plesch May 4 2021, 11:46 PM

Two large boulders, cracked vertically on sol 73, next to each other. Coincidence ? Perhaps the same material, and similar shape, responding to thermal stresses ? With a preexisting weakness in similarly oriented planes ?

Posted by: centsworth_II May 5 2021, 10:08 PM

The discussion of the route south starts at 28:30 of the video: https://www.youtube.com/watch?v=BAlXe-U0ws4
Here is a screen shot. I added the 1 mile long bar. The length of the red-marked zone was said to be a little more than a mile. Also stated was that the science campaign in this area, including sample collection, would last several hundred sols. So a year or more before the rover heads toward the delta.

Posted by: MahFL May 6 2021, 05:02 AM

That kind of implies a much longer mission is anticipated than 2 Earth years.

Posted by: centsworth_II May 6 2021, 07:53 AM

Hopefully! Curiosity, Perseverance's older sibling, is coming up on 9 years and still going strong. From the description in the video, the area they will be spending "several hundred sols" in may be even better suited than the delta for finding biological signatures.

Posted by: Andreas Plesch May 6 2021, 09:46 PM

Sol 74 saw a large 116 image mosaic of the local rock assembly by MCZ. The great Marslife.org does a great job of merging, and I took the liberty to post the result here for quick reference to help locate individual frames from the raw images which is otherwise quite difficult:

https://captainvideo.nl/marslife/index.html

I hope that is ok. It may be one of the largest outcrop mosaics for Perseverance sofar, so perhaps this patch will be studied in some detail ?

Posted by: Andreas Plesch May 6 2021, 10:11 PM

I do think it is a good idea to spend extended time out here since two years seemed very conservative, and chances are that once the rover leaves the area it will never come back. The location is very interesting due to a quieter depositional environment in the possibly shallow lake, proximity to a contact between mappable geological units, and the early observations of a diversity of rock types.

There are also groups which are very interested to visit the area just west outside of the crater which was scheduled for the second year, I believe. So it will be interesting to see if the several hundred days here in the outer delta, lake bottom area, will affect the time available at the actual delta remnants. I cannot really imagine it would but perhaps some kind of agreement between groups was necessary.

Posted by: PaulH51 May 13 2021, 06:32 AM

I'm assuming that this was a 'characterization test' of the rover's arm at a 'teach-point' in front of the rover, with what appears very similar to the canned bricks of organic check material carried by Curiosity (but sadly not used so far)

If that assumption is correct I guess they could puncture the can and return a sample to earth in a sealed sample tube to ensure there were no earthly organics in it as a cross check, if so it could be the first sample acquired / cached?

Or it could be like MSL, only to be used in the event PIXL detects organics?

Does anyone know if either of those assumption are correct?

Google search using organic check material etc has failed to provide an answer for this rover.

"Survey mode. Initial observations will be performed on an abraded patch in survey mode. The laser will fire raster over a 7x7 mm area with 200μm spacing to gen- erate 1225 spectra arranged in a 35x35 point grid. A Raman/fluorescence spectrum is acquired within 1 sec at each point. These spectra can be averaged together to get bulk organic/mineral abundances over the entire scanned area."

Posted by: erwan May 15 2021, 06:01 PM

Thank you Deimos, you are right. Maybe some turret's hardware foot print ? (from sherloc ACI itself ? ; by the way, I presume we see three laser holes on the right of larges pictures).

Colorful multispectral Mars on Sol 77

A

B C

A) Mastcam-Z left eye, filter 0, original RGB

B) Mastcam-Z left eye, filter 0 (RGB channels) and filters 1 to 6 converted to RGB using principal component analysis and color space transformation.
The sky was excluded from the principal component calculation, but the resulting coefficients were applied to it, too (no manual coloring).

C) Mastcam-Z right eye, infrared filters 1 to 6, without filter 0.
Because of the only slight differences in the infrared reflectances of the Martian landscape, the calculated principal components are strongly influenced by inhomogeneities in the filter flat fields, slight pixel shifts (less than one pixel), and probably chromatic aberration. Only the first and second components were used here. The unique blue color of the cliff face and rock fragments on the talus below the cliff in this image suggests a mineralogical composition distinct from that of the dunes and boulders in the foreground and the crater wall in the background.

Anyone know what the name of this rock is?

I think that may not be damage, it looks like it's the 'SLI' (single layer insulation) which is part of the gDRT system. It's purpose is described in this PDF as a blanket of insulation covered in black Kapton tape https://ttu-ir.tdl.org/bitstream/handle/2346/84462/ICES-2019-249.pdf?sequence=1&isAllowed=n, there are some sketches etc in the PDF but they're not that detailed.

Posted by: Steve G May 25 2021, 06:49 PM

I'm really perplexed at the lack of interest in examining the landing hardware up close. Opportunity inspected the heat shield, but none of the Mars rovers have checked out the parachutes (I'd love to see the wind dynamics in them), the heatshields, or the MSL landers. Does anyone have any feedback as to why?

Posted by: nprev May 25 2021, 08:07 PM

Short answers (my opinion but also from what I've heard from time to time from experts):

1. Chutes- risk of entanglement far outweighs any potential benefits.

2. MSL/Percy landing stages- risk of residual hazmat fouling chem sensors, again outweighs benefits.

3. Heatshield- Oppy's was very conveniently located with respect to the science traverse which was the only reason it was examined. The others not so much.

4. Overarching- The rovers are there to do Mars science, not to acquire engineering data on flown hardware. When they're down safely the science team is calling the shots...as they should be.

Posted by: tau May 25 2021, 08:32 PM

Due to an wrong baseline and the resulting incorrect triangulation, I incorrectly located the layered outcrop seen by SuperCam on sol 92 in my last post.
The correct position should be as shown in this HiRISE map here. Now some features in the HiRISE image and in the Mastcam Z images of Sol 92 match better:
A) Remnant of an outcrop or large boulder
B) Large dune
C) Layered outcrop photographed by SuperCam on sol 92
D) Another layered outcrop

Posted by: Tom Tamlyn May 25 2021, 08:46 PM

ISTR some chatter to the effect that there may have been residual chemicals from Oppy's heatshield that were later thought to have damaged the Mini-TES instrument. Or something like that.

Hard to establish or rule out definitively, perhaps, but I can imagine that even a slight indication that it had occurred might have an outsized influence on the risk/reward calculation for similar future proposals.

Posted by: Phil Stooke May 25 2021, 09:16 PM

Backing up nprev's comment on the science - you don't send a 2 billion dollar rover to watch a parachute flap in the breeze.

Phil

Posted by: James Sorenson May 26 2021, 05:27 AM

I can't validate that, But I can tell you that Oppy's rear-hazcam lenses received some contamination as wind blew heat shield particulate debris into them from a small chunk of debris that was in the field of view behind the rover.

This kind of thing MUST be avoided with any of Perseverance's EDL hardware. This is a mission that will cache samples for Earth return and it is very important that those tubes are kept as pristine as possible from any kind of contamination like that.

Posted by: HSchirmer May 26 2021, 10:37 AM

I never knew that 'skidmarks' were an issue with the Mars rovers, and now I can't un-read it...

Posted by: Holder of the Two Leashes May 26 2021, 01:55 PM

Hey, don't they have a helicopter that can examine some of the EDL hardware from the air?

Posted by: Explorer1 May 26 2021, 03:22 PM

Yes, but it is staying near the rover's traverse to image future drive sites for the next few months. And since they are not planning to drive near the EDL hardware, ipso facto, they will probably not fly near the EDL hardware either.
Though to be fair, I also said it would be tough to image Perseverance itself during a flight, and I was glad to be proven wrong!

Jim Bell's LPI talk, which was uploaded to the LPI YouTube channel yesterday, provided a few new details about Perseverance's science campaign which will commence as soon as instrument checkouts are complete (which will be quite soon, if all goes well roughly sol ~100). The video is titled "Delta Bound: Early Exploits of the Perseverance Rover in Jezero Crater"

1) Perseverance's first science campaign will be a loop to the south and back again to the landing site. I always thought that red line was marking a corridor the rover might explore, but he said its actually a (preliminary, non-finalised) plan for a walkabout. I attended a talk on the benefits of walkabouts with regards to Mars rovers in 2019, it's a relatively new strategy of rover exploration that Curiosity trialled at Pahrump Hills. In traditional exploration, a rover basically just drives in a straight line, documenting geological contacts as it goes, whereas in contrast walkabouts involve a reconaissance traverse followed by returning along your route and revisiting certain sites in more detail. It's been demonstrated to boost scientific output in some situations; a major advantage is that the initial reconaissance traverse gives you days/weeks to analyse data and find scientifically interesting sites that you otherwise might have driven past without realising.

2) This campaign might last until the end of 2021

3) They hope to drill 3 or 4 samples in this time, before heading to the delta scarp

4) The lithology at Seitah is inaccessible from the current landing site due to hazardous ripples, however its of scientific importance to collect a sample here because of layering visible in orbital images which could indicate a sedimentary origin. They believe there could be spots along this walkabout where the rover may be able to cross the boundary and take a drill sample

Posted by: Phil Stooke May 28 2021, 08:50 PM

I had the impression from this talk that the return journey would only be taken if no way through the rough area was found at the south end. Could be wrong! Alternatively, it could be a rapid walkabout south and back to the landing area to better assess where sampling might be undertaken. I was hoping to snag a few extra placenames from the talk but there were no new ones.

I will watch the talk. It now makes a lot of sense that Perseverance was sent to the edge of the dune dominated "Seitah" . From there it could gather reconnaissance of the area from a 10m vantage point, including of where layered sediments were spotted. The aerial images should help determine if there is potentially a path to rover access, and improve on relying on just the remote sensing data from orbiters. One could even imagine sending Perseverance further into Seitah, first on a return trip and then perhaps one way if it makes sense. It just needs a small flat area as an air field. Such a trip would demonstrate that such drones can be useful to explore inaccessible areas.

Another layered outcrop in "Seitah" taken by SuperCam on sol 96. It allows to complement the context image from sol 92. The outcrop is that one labeled "D" in the HiRISE photo in this previous post. The distance from the rover to the outcrop is about 600 m.

Someone spotted EDL hardware a few days ago : https://youtu.be/dYZOThUXVmE?t=144

He says it's the skycrane, and though it seems to be the right direction, with the delta in the background, it seems too intact to me; possible the chute and backshell?

Posted by: Andreas Plesch Jun 1 2021, 08:37 PM

The Navcam (top) and the Hazcam(bottom) spotted dust devils 6 minutes apart on sol 99:

Extreme color stretching of the air may show hints of the dust devils as well.

It could be the same one travelling south but we have seen dust devils mostly migrate north in this area. They can also occur in quick succession when the conditions are favorable. Perhaps there is a weather report documenting wind direction at the rover.

Posted by: HSchirmer Jun 1 2021, 09:30 PM

First- I'm quite curious now, perhaps the Gusev Crater 'dust devils' could be the 'genie' Percy needs.
We've all read old myths about "the golden fleece" and the "genie in the desert making you rich"- but IIRC, both of those turn out to have a germ of truth based on density based fractionation and concentration. Hear me out-
There's some interesting evidence that placer gold deposits in sand were mined for tiny flakes by laying down a sheep's fleece, stomping around on the creek bed, and relying on density to trap those placer gold flakes in the fleece.
https://www.sciencedirect.com/science/article/abs/pii/S1040618214005515#
In a similar vein, desert "dust devils" running for miles across desert can sort small pebbles by density, (looking for the citation) which suggests you could follow a dust devil that picked up placer gold and rough gemstones (denser than local sand) and dropped them as the dust-devil dissipated.

Second, bootstrapping from above, curious if the Gusev dust devils might actually accumulate and concentrate denser material as they traverse Gusev- making the final "deposit" point where the dust devil dissipates a VERY interesting sample target?

Posted by: Phil Stooke Jun 1 2021, 09:57 PM

Explorer1: "possible the chute and backshell?"

I looked at this in the sol 57 panorama - it is too close to the nearby crater to be the backshell and parachute. The direction is better for the remains of the 'skycrane' descent stage but I think it's much more likely to be a few rocks that are a bit brighter than usual or happen to have faces oriented to reflect light better - we had a case like that near Kodiak very early in the mission which turned out to be an ordinary rock.

Thank you, PaulH51. Here are two Mastcam-Z context images (sol 105 and 106) with the SuperCam image inserted. I expected the rock to be near the rover. Obviously, the structures (crystals?) are not as small as I thought before.

Sol 106 Mastcam-Z anaglyph:

Posted by: nprev Jun 8 2021, 03:56 PM

Looks like a fairly typical boulder to me. The vesicles are a bit interesting, but what I think you're interpreting as 'crystals' on the right side appears much more like aeolian weathering.

Posted by: tau Jun 8 2021, 07:06 PM

I don't mean the parallel streaks on the right side of the rock. That actually looks like aeolian abrasion. I have a vague impression that there are some elongated structures with different orientations on the top, but that's on the edge of discernibility. A possible rover visit to this boulder could shed more light.

Meanwhile I prepared a stereo image with this rock. Behind the rocks in the foreground a depression is visible, the crater interior. The rock mentioned above is behind the crater. It is probably the big one in the center of the white circle on the HiRISE map. The distance from the rover to this point is about 100 m.

Posted by: john_s Jun 8 2021, 07:21 PM

I agree with tau that there's something intriguingly geometrical about the surface texture between the obvious pits on that rock. Also agree that it's a marginal detection, but it would be great if we could get a closer look.

Posted by: Bill Harris Jun 9 2021, 01:17 AM

I tend to agree with John's agreement.
This rock has an interesting texture. It does "seem" basaltic. But without a close up look and determination of the minerology we can't be sure. The 'vesicles' could be aeolian erosion of softer clasts in a conglomerate. Millennia of aeolian erosion in a thin atmosphere can produce alien-looking forms. And remember, this area has experienced many episodes of deposition and erosion of several types for many millions of years. This area will end up being complex beyond comprehension.
I'm interested in mineralogy and provenance of the flat light-toned rocks that we see emplaced like paving stones.

It avoids having to cross Seitah. Maybe after detailed study of that region they decided not to risk it.

Posted by: Bill Harris Jun 14 2021, 12:22 AM

Let's see if I can get this Quote to come out right.
On the last processed image of the four, there appears to be a bluish ground haze. I presume that it is some sort of processing artifact. What do you think of it?

Posted by: tau Jun 14 2021, 07:39 AM

My intention was to make small differences in hue and brightness more clearly visible by numerical transformations of the RGB values in the color space, not to reconstruct the true Martian colors. Although these processed images show very Mars-like red-brown colors, they are rather false-color images (blue sky). When the color space is stretched, an orange that is less orange (less saturated) than others may move across the gray axis into the bluish region.

As to what causes the haze - I can only guess. I presume that there is a higher concentration of dust in the air near the ground in some places, and that this dust is less orange-red (more grayish) than the dusty Martian surface. Or is it a material difference on the surface itself? But it is indeed interesting to see this haze (or whatever it is).

Posted by: tau Jun 19 2021, 08:46 PM

This round rock seems to be different from the others we have seen so far.
1) Sol 116 Mastcam-Z raw image .
2) Left camera, multispectral PCA image of filters 0 to 6 (mostly visible spectrum). The round rock is as blue as the angular stones in the foreground.
3) Right camera, multispectral PCA image of filters 0 to 6 (mainly infrared spectrum). The round rock is slightly more violet than the angular stones. A small stone in the foreground is clearly different (orange color).
4) Right camera, multispectral PCA image of filters 1 to 6 (infrared spectrum only). The round rock has a distinctly different reflectance in the infrared, an indication of a different rock type.

2) Red channel: sol 114 12:13:29 and 12:13:41, blue/green channels: sol 111 10:49:27

Thank you, vikingmars. And thanks for your interest in my work.

And here is sol 120 with a new SuperCam take and its context. I considered waiting for photos that continue to the right, where there is a very small layered cliff.
But usually the centers of the SuperCam photos in a series are on a straight line, and then the cliff would not be included. Hopefully it will be included in an extra series.

Posted by: Phil Stooke Jun 24 2021, 06:54 AM

Possibly! - we have just 2 images (as I write this) from sol 122, but it looks to me as if Perseverance has moved north to a place near the sol 113 position (a short distance SW of it). That may be an access point for a look at the bright rocks.

Posted by: tau Jun 25 2021, 08:04 PM

A look back, and here is a rather experimental anaglyph of a Kodiak cliff, composed of two SuperCam image series.
Left eye (red): Sol 77, 08:24:49 and 08:37:27 local mean solar time.
Right eye (blue/green): Sol 63, 08:11:26, 08:12:49, and 08:14:12
Somewhat distracting are the different shadows due to the different sun angles.
Different distances to Kodiak, an additional vertical parallax, and axial distortion of the raw images required manual adjustment of various parts of this anaglyph.
Nevertheless, a stereoscopic effect is visible, although two stereoscopic inconsistencies remained in the scree slope.

If you run over it with one wheel it might be better to back up than to go ahead, halving the number of other wheels having to climb the rock.

Here is the context for the SuperCam image from sol 130.
The purpose of the fierce action with the wheels on sol 129 was presumably to excavate parts of rocks which have not been subjected to weathering for millions of years.

Posted by: tau Jul 3 2021, 10:57 AM

Thorough photography of the partially excavated rock

4) Anaglyph

. . 2 . . 3 . . 4

Posted by: tau Jul 3 2021, 01:51 PM

Another possible reason for the wheel action on sol 129: the intention to get a fresh rock surface by driving over a rock with fractures like this one and breaking it (which apparently did not happen).
