Fred, if that's Iazu, let's wrap this Endeavour story fast...

Fred's right that is Iazu again - great view.
As to the height, Google Earth says that the peaks are 200 - 300 m above the surrounding plain. In that image the peaks are about 10 pixels high - at roughly 40km that makes what we can see the top 100m or so. -------------------- My MER & MSL Imagery site - Martian Vistas ---- Twitter Feed (including sol by sol updates on Opportunity's activity)

Wow, what a view!
 I saw that sequence (Iazu's pancam) in the plan but forgot to check it afterwards. The current view at the horizon is, imo, the most exciting since the beginning of this mission. |

James, sorry for asking but, that's not all Iazu, right? There are some features to the right of Cook that belong to Endeavour, or am I wrong?

Craig Covault - speaking live on SpaceflightNow's video coverage of the shuttle launch - has just been saying that MRO has found *clays* inside Endeavour crater... and as (paraphrasing here) clays don't form/last long in acidic water, this suggests that the water there was, for at least some time, less acidic than previously thought...
Anyone know anything about this..? -------------------- |

Stu, my understanding is that the "clays" that MRO has been discovering are the phylosilicates that have been discussed at length, especially in the site selection deliberations for MSL.
I'd have the think that any clays found within Endeavour would have to be remnants of earlier aqueous conditions than those which were involved in laying down the Meridiani sulfate sandstones. And considering there must be pieces of the crust underlying those sandstone deposits in the walls of Endeavour, I guess that's not terribly surprising. Now we need to really hope and pray that Oppy can make it to some of the clay deposits and give them a careful examination. For one thing, clays are the most likely places to find fossilized life remnants, especially bacterial fossils. While Oppy is not all that well equipped to look for anything like that, it could very likely constrain the possibilities in a favorable manner. Take *real* good care of Oppy for us, guys... now, more than ever, it seems the payoff if we get to Endeavour could be truly astounding. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Yeah. When Endeavour became the goal, I perused the raw mineralogical maps available from MRO. I found a very small patch of possible phyllosilicates on the far, eastern side of the crater. It would be significant if newer imagery, or reprocessed imagery was indicating phyllosilicates to be more common.

Today was another driving sol, where almost 70m were covered in a WNW heading.
I would expect a heading change to NW on the next two or three driving sols to avoid some "purgatoids" due west.
PS: Map update tomorrow, if time permits. |

I realized that I should have better referenced the CRISM imagery I referred to in my previous post. The raw imagery I referred to is here. Apparently my recollection of the location was faulty. The small anomaly I described was not on the far, eastern side of the crater. It is closer to the center of the crater. It is on the far, eastern side of the image.
Of course, all the normal cautions apply to any interpretations of such non-calibrated imagery. -------------------- ...Tom (thinks he should use more emoticons)

I while ago somebody wrote, I think it was Phil, that we were heading to higher terrain due in a few kilometers (2?).
Does somebody know whether it's still the case or can we say the western route is just flat for a while? You'll understand that I'm looking for a vintage high place to get a better view. |
