Some false-color closeups of "Comanche" now coming in...
I couldn't begin to speculate what we are looking at, but it's interesting to me that the rock is broken up, and appears to be much darker than the bedrock beneath it. I've been puzzling over this one for a while, in my clueless non-geologist kind of way. I hope somebody more knowledgable throws some commentary out there soon... This just looks like a rock that is trying to tell us something new.
