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.

Absolutely spectacular, surely to be one of the highlights of the entire mission.
Speaking as a COMPLETE amateur, this looks to me like extraordinarily powerful evidence of hydrothermal activity; finding silica would presumably clinch that interpretation. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

... this looks to me like extraordinarily powerful evidence of hydrothermal activity; finding silica would presumably clinch that interpretation. I wonder, whether the dark phase of the veins are (enriched in) hematite or other ores, and whether there may be a connection to Hematite Ridge, interpreting the veins as clastic dikes filling fractures with liquids of a later epoch, and precipitating minerals. May be resolved later with data from younger layers. Short-term I'm hoping for - almost expecting - interesting elemental enrichments in the veins, and possible detection of new types of minerals (for Mars). Although I'm unsure, whether a new drilling will be approved so shortly after the previous drilling. |
