1456 - Abrading has started

AHHH the suspense! Come on relay network, send us the next ones ASAP! I know those sats are busy too, but this wait is killing me.

I really wasn't sure we'd abrade here. I mean, we skip past funky-looking darker caprock all the time (for months at a time when Ken Farley is in a hurry)! Even when the rover can physically reach it. Just look at this stuff, it's craggy and lumpy as anything... but that flattish patch they're grinding: yes.

Even with all the evidence for volcanic deposits around here, I honestly wouldn't guess what this abrasion patch might show us. Volcaniclastic rocks like tuff aren't the hardest for sure, but this stuff forms the resistant layer here. We focus a lot on sampling with this mission, understandably, but I'd love to read more about the science team's deliberations over whether we do (or don't) stop and abrade stuff. We always abrade before we take a sample, so abrasions are just as important as samples in a lot of ways...

Apologies for the word salad. Paul Hammond knows my pain.
