That’s a colourised mosaic I made of three separate pancam images, taken by Oppy as she drove up to “Twin Craters” yesterday. At first glance, TC is, well, not that impressive, to be honest, but I think this is a poor viewpoint; once Oppy starts to move around the craters the view will improve a lot. I have particularly high hopes for that exposed rocky layer on the righ there, that forms the southern rim of the west “Twin” – that looks very interesting in 3D…
These craters are obviously a LOT older than Concepcion, you can tell that just by looking at them: their rims have eroded away almost completely, and there’s a lot of dust inside them. There are no blocks or boulders of ejecta around them either, they’ve all either crumbled away or been covered by dust, so this is an old, old place.
What exactly are we seeing here? This diagram should help (you’ll need to click on it to enlarge it)… You’ll see that we can’t see much of the east crater yet, it’s hidden behind that raised crest that runs between and separates the two craters. Maybe in a couple of days tho. Anyway, just look at the pic… :-)
I’m not sure how long Oppy will stay here, but I don’t think it will be long; after taking a closer look at that exposed shelf over there there’s not ging to be an awful lot to see here, so the drivers will be eager to head off into the open desert again, and towards Endeavour, pretty quickly I’d think. But hey, what do I know? Just around the side there there could be an absolutely fascinating meteorite, or a piece of ejecta from somewhere else completely, so who knows? We’ll just have to wait and see what tomorrow brings; that’s what makes this journey, and exploration, so fascinating! :-)
