I don't believe any placement info for the MI is involved in the PCDB

I would be really interested in seeing the mini-TES runs as we have approached the annulus and as we embark onto it. If the annulus is primarily hematitic, we ought to be able to determine that fairly easily with the mini-TES.
What will be very interesting is if the annulus does *not* appear very hematitic to the mini-TES... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Fooey. Nothing _on_ the ejecta apron, yet, this is from Sol 912 and is an L257 of the ripple trough we were at a couple of Sols ago... --Bill -------------------- |

Whew, who said flat as a pancake! Here is an L7 Pancam from today showing aeolian and (possibly) anatolian features. I _think_ I have the location spotted on the MOC image, let me post this and go offline to check.

Well, duh. You're correct; I was thinking that these "new images" were further along than they were.
Anticipation, I guess. --Bill -------------------- |

When I saw that sol 912 L7 during my morning MMB update, I nearly jumped out of my seat. I had been waiting for a nice view of the step up to the edge of the apron, and was wondering why we hadn't yet seen a more impressive view of it. At least, that is what I interpret Espanola, and I suppose Jesse Chisolm to be now. Stratigraphically, it looks just like the Halfpipe formation, complete with the overlying layered ripples. The 3D view of it is impressive. As we drove further onto the apron I was seeing all of the dark pebbles between the sparse ripples and wondered why. I was expecting the apron to be totally different. I'll take my geologizing over to the halfpipe topic now.

In the lastest Navcam pans, we can see a light-toned area extending to the SE in the direction of Victoria's rim, and this area corresponds to the light-toned area between the windgaps in the crater rim visible on the MOC Route Map image. Close in, we can see that this light-toned material seems to be associated with the transverse ripples caused by the SE wind and we can assume that this light-toned material is likely eroded evaporite material from the rim of Victoria. I'd guess that the prominent dark streaks we see on the ejecta blanket are simply the absense of the light-toned dust. We'll see a a couple of Sols.

Just been looking at the tracking site for tosol (919) and I see we have this:
CODE 919 p2572.16 4 0 0 4 2 10 pancam_pre_trench_L257R1 Looks like we're going to put a trench in the annulus over the weekend. Does anyone know if Oppy has done any (intentional  ) trenching since the the steering motor failure? I can't remember any. I would imagine that that would affect they way trenching is done compared to what we saw back in the early days. Should be an interesting weekend.

I was ready to say "Yes!", but then I saw the "intentional".
