Sols 4259-4260: Kings Canyon Go Again!

Earth planning date: Monday, July 29, 2024

Our weekend drill preload test on the target “Kings Canyon” (shown in the accompanying MAHLI image) didn’t give us the full range of data we need to move forward with the full drilling process. This coming Wednesday, we hope to rerun our preload test on Kings Canyon or somewhere very similar on the same bedrock, and to get APXS and ChemCam analyses in order to determine scientific suitability for drilling. As a result, this plan focused on getting the arm ready to fulfill those diagnostic activities, described by our Science Operations Team Chief Elena in last Friday’s blog. 

In the meantime, we are in such an interesting area that we have a very long liens list (our wish list). Our problem today and probably for the foreseeable future will be a good one - trying to keep below our upper limits on how much of that wish list we are going to try to get in on a given day! 

We have recently seen examples of bedrock slabs or outcrops with a flat, paler toned centre and a rim of darker, greyer material which surrounds the main slab. We saw this about 50 sols ago at the Mammoth Lakes drill site and we see it here too. The relationships between the centre of the slab and the rim are very intriguing and we are keen to understand the interplay between the two textures. Mastcam will take two large mosaics in this area. “Sam Mack Meadow” is a 7x4 mosaic (i.e., 4 rows of 7 images) on an area of crushed grey material, and “Merced Grove” is a 7x6 mosaic on more intact rim material. ChemCam have also planned a LIBS analysis of Merced Grove and one at “Clinch Pass” in the centre of the block. Together these activities will help us to look at relationships here and to compare with previous examples, such as at the Mammoth Lakes drill site.

ChemCam will acquire a passive measurement on “Wilts Col,” a small dark toned float rock about 4 metres away from the rover as part of a continuing campaign to assess the nature of the floats (loose rocks) which are strewn around this part of the crater. ChemCam will also acquire 2 RMI (long distance images) 10x1 mosaics, looking at the stratigraphy and layering of the distant hills – getting a head start on the science assessment before we even get close!

The atmosphere and environment science theme group (ENV) also crammed their section of the plan full of activities. Since landing (almost 12 years ago now!!), the ENV group has been reporting on environmental conditions in Gale, and this plan was no exception. We have some regular DAN passives, REMS activities and a Navcam dust devil movie, and a single Mastcam “Tau” measurement, which looks at dust in the atmosphere.

A grayscale photograph of the Martian surface shows, in the foreground, medium gray soil that looks like wind-blown sand dunes, with a few rounded, medium-sized rocks poking up from the ground. Beyond this area, and covering the upper half of the frame in this circular image, is much more rocky terrain, with both sharp and rounded rocks of all sizes covering the ground.

Sols 4368-4369: The Colors of Fall – and Mars

Article1 day ago
A grayscale landscape photo from Mars, showing a broad, medium gray, rock-strewn plain in the foreground extending far into the distance, surrounded by several hills. The closest hill, in the lower right corner, rises up toward the side of the frame, and is darker than the floor below. A little farther out, on the left, a gentle slope rises from the low middle of the frame to middle of the left side; it’s about the same color as the valley floor, except for a band at its farthest edge, which darkens abruptly as if covered in shadow. The terrain appears softer than the ground below, more sandy than rocky. Beyond that along the same rising plane is a much lighter area, with scattered tiny peaks that are darker – looking like the top of a baked meringue pie. The channel floor runs between these hills, then appears to curve toward the right, behind the first hill and in front of the second. Finally, one other rounded peak appears above the horizon, behind these other two hills in the lower right of the frame, all of this below a light-gray sky filling more than half of the frame above.

A close-up color photo from the Martian surface shows a pale orange rocky outcropping, which looks on top like a sheet of coarse sandpaper, and on the side facing the camera like the feature is made from numerous, stacked thin layers, with undulating edges that make it look like a topographic map. Atop the feature are multiple plates of smooth stone in the same pale orange color, in different shapes, at different angles to each other, with a texture resembling clippings of thick, dense felt.
