Atop/Around the Greenheugh Pediment, Site 79-, sol 2695-3199, 3 Mar 2020-6 Aug 2021 Options

[PaulH51]

Sol 2695: Just a short drive / climb, but a very welcome one to get all 6 wheels off the slope and onto the top of the pediment
Roughly stitched L-NavCam partial pan using MS-ICE with the available images. I'm sure the full 360 will be memorable...

BTW: maybe a good time for a new thread? (Traversing the Greenheugh Pediment?)

Stunning, Sean.

Re new thread: Yeah, possibly. That's Emily's call, though; she's been most carefully curating the journey of MSL here.

Greenheugh pediment looks like its going to be a rough traverse for the rover. What does the pediment represent?

Not sure, but you might find this LPSC abstract interesting:

https://www.hou.usra.edu/meetings/lpsc2020/pdf/2337.pdf


Originally the pediment was interpreted as an alluvial fan, sediment swept down Gediz Vallis by flowing water, but that's not the prevailing view at the moment.

How do you pronounce "Greenheugh"? (Not evident for a French speaker.)

[centsworth_II]

Not evident for an English speaker either!

[djellison]

Everyone I’ve heard say it says Green Hue.

Hi folks, new rocks, new thread! Here's a link to the spot in the Route Map thread where Phil et al. documented this moment.

[PaulH51]

Partial end-of-drive R-Navcam pan from sol 2700 (Site/drive 79-588) hopefully to assist in pinpointing the location while we wait for the remaining frames.
The plan stated they were driving west looking for a drill site... This location appears to tick some of the drill site boxes

Ant, are those images available for download? Am having some trouble figuring out how. Sorry.

[Ant103]

@tanjent : which images ? The panoramic ? If that's the case, just follow the link by clicking the picture, you would find a gallery with the image, and links bellow.

Edit : Sol 2700 Navcam panoramic.

This is caprock so it might be hard to drill. I hope we get one!

[PaulH51]

This is caprock so it might be hard to drill. I hope we get one!

It would be nice to see them drill / sample one of those darker (capping) rocks, but because of the Feed Extended Drilling) they would need to find a really stable candidate...

However, the first potential drill site candidate appears to be in the lighter toned bedrocks seen in the arm workspace on sol 2700.
Attached is a mosaic of the L-MastCam images of that workspace, I believe the candidate is the Trapezoid shaped block in the upper right of the mosaic.

[PaulH51]

Looking towards the edge of the Greenheugh Pediment and some rather nice strata seen in this R-Mastcam partial pan from sol 2700, debayered in GIMP and stitched using MS-ICE, no additional processing, so apologies for the green hue as I can't find a way of removing it.

Edinburgh drill hole on sol 2711, judging by the HazCam images acquired during drilling and the tailings shown in this L-NavCam frame there should be a good chance of a viable sample in the sleeve

Thank you for that nicely debayered and stitched pano of the sol2711 mastcam set. Its quite a view and am especially intrigued by highly eroded sections especially as seen in the snippet of the pano below, representing this pair of snapshots, looking closer a sinuous curve of apparent eroded pediment boundary appears sharply shadowed appearing in the exposure as if it were some sort of slack cable draped over the landscape. I keep losing my bearing as to where we are so have no idea if Curi is heading towards that particular area or onward elsewhere..

We had this MR view of that feature, though with a bit different lighting:

Postcard version :

[PaulH51]

Lovely work Damia, looking forward to seeing more of your excellent panoramas!

Meanwhile, another long distance RMI mosaic across the pediment, this time wider view (19 frames from sol 2719) It was roughly assembled in MS-ICE without additional processing.

[atomoid]

Indeed a very lovely view, the composition gives a feeling almost of a Martian sort of tropical, taking in a relatively balmy afternoon as wavelets of sand gently lap up against the near shore and relax sipping a perchlorate cocktail under the instrument cluster standing in as mock parasol, take a glance over near to the right a bit into the distance many barchan dune islands poke above the surface as the seas of sand grow rougher dissappearing into the murky distance, in splendid isolation I will be to remain here for some while..

Yet another long range ChemCam RMI mosaic checking the distant terrain, this one appears to focus on the hills beyond the Greenheugh Pediment. Images from Sol 2725, composed of 12 frames assembled in MS-ICE without further processing. Note, there appears to be 14 images in this sequence, but one processed frame has not made it to the server as of the time of this post.

[serpens]

I may be a tad bidirectionally challenged, but isn't that the marker bed?

[PaulH51]

I may be a tad bidirectionally challenged, but isn't that the marker bed?

I'm not sure, but I'm guessing you are referring to the 'marker bed' described in this? link

Here's where I think the terrain is, I've added a box to a mosaic assemble by Neville Thomson showing the other long range RMIs from atop the pediment link



Edit: We now have the mission update that covers this sol:

On the second sol Curiosity will take a ChemCam long distance RMI mosaic of the pediment capping unit to assess the stratigraphy and sedimentary structures exposed on the flank of Gediz Vallis.

Here's a little more detail in this telephoto ChemCam-RMI from Sol 2726, roughly assembled in MS-ICE, some data drop out in one frame. No additional processing except the stitch and adding the text.

[Phil Stooke]

Thanks, Jan. Here is a circular view of it showing how we have moved away from the edge of that depression. The recent updates have indicated we will drive off the pediment and resume the previous path around its edge to the east, then up into the hills.

My take on the MastCam Right mosaic of sol 2729, with 5 extra Matt Damon added to give a scale
The furthest one is at ~580m from Curiosity rover.

[Phil Stooke]

Don't jump, Matt! There's still hope for a sequel!

Also, here is Jan's new panorama in circular form. We have moved right to the edge of the pediment again at the same place we climbed it earlier. The tracks are visible just below us.

Phil

[serpens]

Found Wally. Thanks for the humour neo.

[atomoid]

Thanks neo56 for the great image treatment, i inspected jvandiel's stitch of the same sequence yesterday and was frustrated trying to get a handle on the scale of things, and since i tend to overestimate the scale of things in the near-scope pancams, i now see im overcompensating for the larger scale sequences, i so misunderestimated that protruding part of the rock to be only about the size of Mark Watney's boot, off by over 3x..

Right off the pediment! We ended up just about at the sol 2658 location - get those brakes checked, Curiosity! The map may be delayed a day or two because people won't leave the Moon alone.

This thread might have to be renamed 'Around the Greenheugh Pediment' because that's where we will be going now.

[mcaplinger]

Was it always planned for the rover to descend off the pediment back onto the clay unit or did I miss something?

AFAIK this was always the plan, but I'm not sure if it was explicitly said or just somewhat implied in the status reports.
See https://mars.nasa.gov/msl/mission-updates/8...diment-for-now/ and note the use of the phrase "mini campaign".

[Phil Stooke]

One of the most important targets of the entire mission is the contact between the clay unit in Glen Torridon and the sulfate hills above it, which is assumed to mark a major change in global climate from (let's call it) moist to arid. The Pediment straddles that contact, so if you stay on it you have missed the crucial exposures. They went up because it was possible at that location, so why not have a quick look at it in case a failure ends the mission before they meet it again higher up the mountain.

This LPSC abstract shows the planned path ahead, as of just a few months ago.

Does anyone know if the figures from this abstract are available at a higher resolution? Maybe in another document, or a large poster?
I'm particularly interested in Fig1 that shows the MSAR version 9 or later
It would be nice to see the detail of the proposed path around the pediment up to the sulfate hills

[atomoid]

One approach is to use the HiRISE browser search for Gale and zoom into the Gedis Valles area and pan and poke around through the madly overlapping needles in that haystack to find the good views like this one. some of that area was also in the 50th LPSC abstract

[Phil Stooke]

Paul:

"It would be nice to see the detail of the proposed path around the pediment up to the sulfate hills"

That image will stand quite a lot of enlargement. I don't know a better source yet.
