I had a dream last night where I was looking at images in this forum topic which showed a single "berry" on the soil which kept disappearing and reappearing, with a fade-in, fade-out effect. Smile

Horton, re 219 : "In the meantime, how many types of minerals can you see in this image?" I am not able to visual identify minerals as well but I guess a commentary on my re 216 Gigapan summarize it very well: "Rich grounds!" Very Happy

Stumbled across some fun observation while preparing the final Sol 192 Gigapan (170 single images).

Look at that odd shape(s) and according shadow(s) in the upper right quadrangle of that image! Very Happy

RE 250 - MPJ, are you referring to the berry on the stalk; and the rock it its sitting on?

RJS, I wouldn't actually call it a berry on stalk so Iam not sure but here is the full 192 pan and a link which brings you directly to the feature Iam refering to in re250:

Thanks RJS - glad you like it. Smile

Another keen viewer of the panos pointed me to some remarkable observation of changes between Sol 173 and 192.

Looks like this patches of bright white material - mostly observed in shadows - really is some volatile material.

An appearance of frost/ice stands to reason I would say. Wink

here is the related 173 pano (snapshot): http://gigapan.com/gigapans/124341/snapshots/317650

MPJ, Awesome find. I hope NASA took notice.

Sol 0173 0192 3D animation of frost ( what else could it be?! ) under the rock in reply 228:

Truly an awesome find! What is needed are a few more examples like this to demonstrate habitability at this place right now!

A couple of well placed laser zaps should prove the assertion scientifically.

Very good morphing comparison above Horton. This makes it quite clear. I still had some vague doubts regarding the 'light shining trough' issue encountered previously. Smile

Now what kind of frost could it be? Dry ice wouldn't be stable even at the lowest temperatures measured that sol (-66 degree C) unless the cavity under that rock would be an extraordinary cold trap during late afternoon.
H2O frost on the other hand would be a nice water source (liquid while melting/vapor while evaporating during the day) for any putative micro-life in and around the host rock. This would also make all the microbial mat and/or lichen suspicious observations in this area even more reasonable. Wink

Yes this kind of observations - maybe accompanied by the "desert mantis" of re223/225 - would make the MSL mission of determining current habitability a childs play and would relieve the NASA crews from this nasty mission objective to do some important things like cleaning their equipment and mindlessly laser zapping Martian dirt without any obvious scientific results (yet?).

Maybe a mobile Mars organism sheltering in the cave, coming out once in a while to take a look?

I think it looks somewhat like a thick viscous fluid.

I agree that it looks viscous. Perhaps in dried form it comprises the lighter colored rock upon which it and the rock it is under sits? See, post no. 228.

Whatever it is - I keep accounting it to frost for the moment - once you seriously start looking for it you will find alot more manifestations. Only restriction seems to be a shadowed place - it doesn't matter how the surface it appears on is orientated. Need to collect more example to refine a definitive declarative for the constraints of this stuff (time/space/environment). Unfortunately we still have not seen humidity readings from REMS...

Here is one more example in the Sol 198 (preliminary-) panorama (related to Johns linked image above):

Also some more interesting observation regarding visual manifestation of past/present life beyond the blue/green bubble mats in the Sol 173 pan:

Curiosity has gone into Safe Mode nothing serious as the back up computer has taken over but annoyingly halting the latest sample analysis.

Its still a few days left to the big conference so nobody seems to be in a rush with the big SAM analysis. Smile
Hopefully they can sort out the computer problems - I would be "a little bit" concerned if my systems would have to switch to the redundant backup after just over half a year of service and a projected mission length of 2 years... Confused

Any fossil hunters out there?

Here is another fun observation in the Sol 192 near field:

Martian rocks bearing some uncanny resemblance to Earth objects of biologic origin (possibly a Parasmilia excavata of my personal collection) - who needs biology if geology can replicate all kinds of organic shapes all by itself (especially on Mars of course).

The more time I spend in those Yellowknife Bay panoramas (snapshot of the above crop: http://gigapan.com/gigapans/124324/snapshots/317543 ) the more I get the feeling it is more of a paleontologic field site than a geologic one. However NASA Scientists+Mars=Eyes wide shut... Very Happy
