Why not take a median image as your basis — analogous to astronomical flat fields?

Good idea, Steve. I'd been meaning to write a median routine for some night sky work anyway, so here's a quick-and-dirty median version of the 2228 DD:

And a version added to each original frame:

With respect to the apparent patchy nature of hematite along the ridge the identification of intermittent Cu enrichment by Chemcam https://www.hou.usra.edu/meetings/lpsc2017/pdf/2894.pdf raises one possibility. Even trace amounts of Cu++ provide a significant catalyst for oxygenation of ferrous iron. http://www.gfredlee.com/SurfaceWQ/StummOxygenFerrous.pdf

Huge improvement. Great teamwork guys

Was Curiosity going to try to image the Insight entry at all?

Was Curiosity going to try to image the Insight entry at all?

The mission update for the weekend and today did not get posted yet, but looking at the distance to the lander it was probably a stretch to have imaged the parachute, possibly a bright streak in the sky? I guess it would depend on the position of the sun in the northern sky. I hope they had a go....

There was too much crater rim in the way for Curiosity to see InSight. Even at entry, it was not visible through rocks. At the time of peak heating, it was a bright streak well below the crater rim. By parachute phase, it was below level.

Pity, would have made a great outreach image
Meanwhile here is a rather nice long distance image of Mt Sharp, simply stitched in MS ICE, no additional processing

Just ChemCam and Mastcam images at the moment, really hoping for MAHLI closeups to be released.

A quick ChemCam + Mastcam merge:

Sol 2247 panorama is gorgeous.

EDIT: A full version can be found here on my website.

Sol 2247 panorama...

Looks like there are few sets of long range RMI's during sol 2249 featuring selected parts of this panorama, some of them many be suitable for pan sharpening?

Curi drives away soon, I was hoping for a MAHLI Selfie with that backdrop, it would have looked special, but hopefully we may get one after they drill the Red Jura (plan)

[djellison]

I think the aim is to be parked at a head of 0 deg for the Red Jura drill site - so that would put the future path in the background of a selfie.

[PaulH51]

...that would put the future path in the background of a selfie.

Thanks Doug, fingers crossed for a successful sample acquisition of that tough Red Jura member, then I may get that selfie
The ~30 minute drive mentioned in the plan took place on sol 2250, attached is a partial pan assembled from the available end-of-drive L-NavCam's that may assist in narrowing down the location. I used MS ICE, with no additional processing.

This shows the Lake Orcadie and Highfield areas in context. They were very close together.

Would someone care to comment on the CU enrichment? To me it seems fairly significant. IIRC, the Deep Impact mission used a copper impactor because CU is so rare in comets, and I think it is fairly rare on rocky planets which implies some sort of enrichment process. Would this enrichment imply some hydrothermal action?

Thorough inspection of the elevation mandrel on the mast on sol 2250.
