Apparently we are now in a new quadrangle. Names from the latest status report include Sherwood Forest and Troll Valley, taken from the 1883 novel The Merry Adventures of Robin Hood by Howard Pyle. Previous quads took names from geological features of the areas which gave the quads their names. I don't know what this quad will be named. If anyone can fill us in, I would be grateful.

Well I can't claim to have seen a reaction like that to a ChemCam LIBS session ) I believe this may be one of the MAHLI's of the sol 1821 odd looking ChemCam target I posted a few days back. Rotated & cropped, in raw colour and presented side-by-side with the RMI. Looks like the liberal coating of dust and the darker bedrock gave us the interesting B&W image |

That does seem to be the target, good eyes there Paul. The RMI operating range is 400 nm to 840 nm so there was possibly a big spike in one section of the reflectance spectra.

I think this sol 1822 ChemCam target is Hypocrites Ledge, I added the R-MastCam context image as well as a small mosaic of R-NavCam images to the 4 frame RMI mosaic. AlgorimancerPG was used to create the scale bar.

Well the depositional environment is certainly changing as we get closer to the top of the ridge.

Almost looks like tree rings. Very uniform in thickness I think. Seasonal?

A circular view of Jan's new panorama. Soon enough - a month or two perhaps - and we will be looking into the stunning terrain south of the ridge.

There are a number of factors that could have influenced bedding formation that are not necessarily cyclical. For example changes in the sources of sediment and variations in sediment supply, water depth and velocity, changes in climate or local environment, wind velocity and direction if aeolian, airfall from volcanic activity or impacts and so on. There should be some interesting papers in the next LSPC.

R-MastCam from 1821 which is the context image for the ChemCam target called 'Mustards Island'. We can see the LIBS locations as bright specs which are very similar to earlier LIBS sites on iron meteorites, but I've not yet seen any reports from JPL, I guess we have to await a paper, or a Photo Journal post
Using AlgorimancerPG I get a width of ~6 cm. |

Yeah - that was a fun shift yesterday (1829) - did my best to raise the drive direction (ncam00267) to cover Mt Sharp without getting a hole in coverage between it, the Workspace (ncam00375) and the ChemCam targetable region (ncam00312) - a lot of back and forth, relying on an end of drive pitch/tilt to make it work.
Super relieved that it all worked out |
