Drive during 1944, L-NavCam pan roughly stitched in MS ICE be should be good to help pinpoint the location. (the plan called for a 25 meter drive south)

New thread! Please keep sharing sol 1943 self-portrait work in the previous thread, and carry on discussing the ongoing mission here. Curiosity should be driving east across the top of the ridge for a little bit, chasing interesting CRISM pixels, before driving down into the valley. If we're lucky we might see a little action with restoring the drill to service, too.

Sol 1944 Navcam pan smile.gif Do we have a name for "the Valley-Behind-the-Ridge" (my temporay proposition for this place) ?

Gerald
The most common informal name seems to be "Phyllosilicate Trough", see e.g. here.

Since Phyllo means "sheets/dough" and silica means hard, are we going to get placenames based on pastries?

Gerald
The phyllosilicates form a large class of silicate minerals, with the clay minerals as a subclass. Phyllosilicates have been identified by CRISM in the Phyllosilicate Trough (see e.g. fig. 6 on page 1723 in the paper).

Drive on 1946, here is what I could salvage from a rough stitch of the available L-NavCam's, hopefully it may assist in refining the location (mods to delete when the full version is posted)

Incoming !

Still some pictures to complete it, but Sol 1946 is pretty, we have a good view on "Phyllosillicate Valley".

Edit : complete smile.gif

For location purposes I did a rough patch of Damia's panorama and made a circular version:

A long distance RMI mosaic, roughly assembled from 9 overlapping images acquired on sol 1948.
The early pointing data on Joe Knapp's image page suggests that it is located Southwest of the rover, if confirmed then it could be a valley Mesa or a section the north side of 'Phyllosillicate Valley'.
I see a possible candidate on the NavCam images, but my monitor is poor (like my aging eyes). It could be mentioned in the weekend plan, but I've not found it yet. Thankfully we often get associated MastCam context frames with these image sets, hopefully we'll see it soon so we can establish the actual location.

EDIT: As often happens, another image from this set has come down which extends it to the left side a little. I wont flood the server by posting the updated version. Maybe we will see one of those rather nice pansharpened versions (hint) providing the MastCam images have enough detail smile.gif
PaulH51
Looks like a nice drive (>20 meters?) on sol 1949. MS ICE does not want to play ball with the available images, but there is a lovely view West of the rover's tracks as it drove back onto the top of the ridge. Looking forward to seeing the full pan with a nice view of what awaits us in the valley.

I roughly patched Damia's panorama for location purposes - here is a circular projection of it.

I thought this might look amazing in 3D. I wasn't disappointed.

The wide exposure variations once again defeated MS ICE on the sol 1950 post drive L-NavCams. I managed to salvage this small section, hopefully it will assist in narrowing down the location until the full version is posted.

Don't give up Paul. Maybe try a different stitching software.

Beautifully crafted panorama Damia smile.gif I do hope that one day I can learn how to use some different software... Thankfully there is always lots of inspiration in this forum smile.gif

I have sometimes found that I can encourage ICE to work by doing some preliminary exposure adjustment to better match adjacent frames.

I did try that with this batch, maybe I overdid the lightening of the darker images... More practice needed smile.gif

Postcard from Mars: with the particularly low atmospheric opacity these days, we have a crystal-clear view on the distant rim of Gale crater. What a vista!
This is a section of the sol 1950 NavCamR panorama with an extended sky.

A stupendous view indeed. It would be a particularly good one on which to mark the whole route travelled so far. I'm especially enjoying the reminders of earlier parts of the journey, such as the reappearance of the little hill to the east I used to call 'Dumgoyne' now seen from above whereas we were looking up at it from Yellowknife Bay.

Very nice Thomas smile.gif I'm so pleased they named some new features, particularly the large crater in the western rim wall, it's long been a landmark for me to decide where the rover was pointing. I hope they continue to release the names of the vales, gorges and Mesa's etc in the months and years ahead, it makes it so much more enjoyable to follow along and the share the mission with others.

Meanwhile on Mars: sol 1955: 5 frame RMI mosaic of 'Bloodstone Hill' (roughly assembled in MS ICE), I guess there could be more images, but this is all they had when I processed these

Well, you might try a "suture" - a small image created from the edges of adjacent images, manually matching scale and exposure.

This roughly re-creates the "identify 3 match points" that was common in old camera stitch software.
PaulH51
Thanks. I'll see if I can find out more about that 'suture' process smile.gif
EDIT : No drive on sol 1957, but the rover took another NavCam 360, so I have deleted the roughly stitched pan I posted earlier as it's the same as the one posted on 1950

The other suggestion, see if you can dig up a copy of Canon's Photostitch, circa 2003
that had the incredibly useful ability to set manually forced match points.

I've got the .iso somewhere....

One of the telephoto RMI mosaics from sol 1959, roughly assembled in MS ICE with a little pre stitch processing on some of the frames. The 1959 mission update states that some of these long distance mosaics were checking various steep slopes to look for evidence of grain motion downhill.

Looks like they have completed the long awaited drive to the NE on 1962, path looks like a dogs leg, but the point to point may be around 50m. Still playing with ICE sad.gif
neo56
I stitched a couple of MC100 pictures focusing on the foothills and outcrops on sol 1957 and 1959. Photos are taken at ~12h local time, so not a lot of contrast.







I also combined a recent RMI mosaic taken on sol 1961 with a MC100 picture to show the location of the outcrop that was imaged:

Great pictures, everybody - what an amazing place we are coming to! The next few years are going to be spectacular.

Good spot Thomas smile.gif
The possibility of using the drill at this location is also addressed in the sol 1963 mission update
PaulH51
The 1965 mission update calls for a 360 MastCam mosaic, maybe to support that they have also acquired a NavCam set of the Rover deck smile.gif Should be an impressive panorama from this vantage point.

There is also a nice candidate for another iron-nickel meteorite in the arm workspace, the team are going to be here for a while if the ground is suitable to attempt drilling, so maybe they will give it a zap to see if it is iron, I hope the coating on its topside is not dust, maybe wishful thinking that is a ferrous oxide, or maybe where is was in contact with a rock (if it was buried in the sediments)

Phil Stooke
This is part of Paul's workspace mosaic (with a little patch), posted earlier, annotated with recent activities.

FYI (from Ashwin), the smaller pile (upper one in your view) is the sieved (fine-grained) sample, the larger pile the unsieved (coarse-grained) sample.

Curiosity update forthcoming.
Phil Stooke
Thanks, I was trying to decide which was which.

Suffering through a bit of an image diet here, but it looks like we had a successful drill on 1977. Here's a comparison of images 2 sols apart.

Good eyes as always Phil smile.gif
Looks like the drought may have been eased, with the arrival of 100+ L-MastCam full frames from the 360 pan acquired on sol 1965, although I would rather have got the NavCams from the recent pre-FED & FED activities. But we did get a bonus in a sol 1971 RMI of what appears to be (to my amateur eyes) suspiciously like another iron meteorite candidate in the current workspace smile.gif
The 360 pan frames are all Bayer encoded, so I cant do them any justice, hopefully the image wizards here will be able to use those and the NavCam Deck images to make another masterpiece smile.gif

High five to the whole team! The drought is (almost) over!
Only step 1, though, as this press release explains.

Going to try drilling again, need to be deeper to obtain a sample, but first the DRT and APXS will assess the new target (Lake Orcadie 2) roughly 7 inches to the right of the first hole. Link
