And my take also on this pan smile.gif Enhanced levels in order to pop-out some details on the rim's mountains.

...The Sol 78 pan is also pretty nice - especially the crazy stone on the left side ...


seems almost as if that crazy stone got flipped upside down (reminds me of Natural Bridges beach formation in my hometown before it collapsed), and there do seem to be a lot of rocks where the part in contact with the sand seems to have eroded much more (and recently exposed) than the more perennially exposed part, seems there could be multiple things going on geologically speaking (and of course admittedly including some observation bias).

heres another interesting protrusion (stovepipe with 'mouth' agape to right).

At last - a small movement. I'm still trying to characterize it, may be mostly a turn in place. EDIT - no, they have moved so the rover is sitting right on top of the little drift from which samples were scooped. Compare front hazcams with sol 56. Route map update on Monday.

Ant's second half-pan in circular format. Looks like Curiosity backed up to the north slightly, then drove south just a couple of meters and turned clockwise a bit.

PS It will be interesting to see how the 'triple junction' at Glenelg is examined. Three units - the fractured and layered rock of the high thermal inertia unit, a cratered plains unit and a hummocky unit where Curiosity landed. Ideally all three should be analyzed and their contacts examined. We've been on the hummocky unit but it has not really been analyzed thoroughly (the scoops were all in wind-blown dust on top of the hummocky unit) - so we presumably have ChemCam data on parts of it, but reallly nothing else. So will we see stops on all three units, or will attention focus on the fracture hi-TI unit with the rest left to photo-geology?

Perhaps aiming for co-located DAN measurement?

This 3D view really shows, I think, the rugged nature of area of the floor of Gale Crater where Curiosity is now...

Question - if you look at Navcam images of the scoop area, there are several little dark spots in a cluster just across the top of the drift from the scoops. They were there on sol 84 but not on sol 74. I'm not sure if they are ChemCam laser holes or spots where bits of debris fell out of the scoop. I don't see ChemCam images which look like they are of this area. Any ideas?

Phil

Here that found. Chem Cam on sol 79
upd: I think, from below - a pebble trace.

It is great! Earlier than on an official site? rolleyes.gif


Interestingly changes of a dust in a trace.

... and a circular version of that panorama - right on the edge of the good stuff.

Wow! Probably there was a small dust storm on sol 100.

Unlikely - it's just terrain seen at a different time of day at a different angle. You're not accounting for the autonomous stretching done to the image.

I will add that it's just a variation of the atmospheric opacity. But there's no dust storm here.
