Once I made a slide of a small blister/papule from the skin surface, and found upon examining for possible very large virus or cells rutured at 2,000x view(down to about 1/3 micron lower limit size range), a very obviously mechanically perfect flat transparent plate, upon which was a regular grid pattern of offset holes, about a miron in size per hole, spaced about 3-5 microns apart. Finding an object like that in human body fluid sample can be a life changing event. It was partial, small, and broken. I had to feref my suspicions to the source of the slide, which was a Electron Microscopy supply vendor, but just seeing such an unexpected sight in a sample can alter range of human imagination. These various unidentified suggestive 3D items we find on Mars are hopefully having that effect in these groups studying the return photos. Whatever the outcome, we are perfecting an approach to group analysis of possible first sightings of new discoveries.
As I mentioned prior Horton, the best strategy for acclimating to that medium is try the Stardustathome site image stack 'movies'. They show a near limitless range of silicone type inclusions, bubbles patterns, landscape0like structures, and some of the most organic looking shaped items I've ever seen. I imagine we'll not know which transparent items are really particles without shadowscast, or some inclusion contents showing. I would certainly like to see a drop or two of liquids.
Did you notice the very flexible and 'strechable' membrane like bright item at the left side of the 'poppy' shaped bulb? It was in the linear string of rounded colored micro-spheres in the diagonal path to the left.
That bright membrane like shape seems to have modeled the available surface of the substrate, as did the prior particles I had displayed in the early 'nano array' OM images. The material has tensile strength, apparent flexibility at -10C to -100C, and is seperately a struture of a single material in appearances. Quite a tall order for any non-living mineral material, even a clay type. We see so much of these examples over the years on Mars, yet it all seems to slide into obscurity again and again. I think history has been made.
A device to capture frost by diurnal deposition, and utilzing sublimation pressurization, could give a small percentage of the Earth's CO2, as we know. Why not a system of non-vascular life with local energy production, for available gas pressure? Skipping the pressurized transport would save most all the complexity and energy expense of a living item. It could also be a frost-to-gas chamber for a low pressure system?
I'll look for the bubble or gill shapes when I return later today.
