Finally drove away from Pahrump Hills on sol 923. Wheel tracks sure are piling up at the end of the drive -- there seems to have been quite a bit of slip.
[admin note: I was going to start a new thread for this, but realized our thread naming may be a bit out of whack because we're really not journeying to Mt Sharp anymore, are we? We'll discuss it with admins and I'll move/rename posts when we figure out our naming schema.] -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Sol 930 Right Mastcam image of a dump pile, probably of the Telegraph Peak drill powder.
This simplifies arm movements, e.g. for MAHLI wheel imaging, and opens an option for a next drilling. With respect to the Garden City MAHLIs, here an annotated crop of this Sol 930 MAHLI: With an interpretation of the darker phase as partially brecciated mudrock, having lithified a little faster than the light-toned fine-grained phase, I could get a more or less consistent view of the image. Both phases look rather resistant to erosion by considering the angularity of the surface; the darker phase maybe a little more resistant than the light-toned phase. Each of the two presumed phases may vary a bit in composition. The part which doesn't like to fit easily into this interpretation are the parallel-looking features I've annotated by green lines. Initially I've been looking for cleavages to narrow down mineralogy, but instead found these linear structures, which don't seem to care too much about the remaining structuring of the rock. |
