I think there are fungusy ones because we have images of them on stalks. The image of the 'round things' emerging from under the 'rock' shown in the black and white image above with the NASA arrows in it, shows what I think is different from the RAT image just above. I think the ones that are just emerging from under the not-round blueberries in the B&w pic above ARE fungus. The other thing I thought of was that if these blue blueberries are dropped out of the rock after weathering, then, over ages, there would be many of them. Where are they? They should all be blown by the wind into piles behind large rocks which give them shelter.
I suspect it is another NASA red-herring or made-up image 'cos I cannot reconcile the reality of both blue blueberries and fungus blueberries. And what is more, I think that this dust/very fine soil is the spores from all these fungi.
Very, very interesting ! Those cannot be fungus, as a fungus would not hold a circular shape when ground and would not permeate below the surface of the rock in the same circular shape. In my very uneducated and humble opinion, it must be some sort of a chemical/mineral deposit that creates a spherule shape during formation and must be of a similar age to the rocks it is imbedded in ? It may be of a harder substance so that weathering of the rock around it (which may be very soft for all we know) leaves it lying around on the surface in the area such as we have seen in images. Perhaps it was something commonly used once upon a time like gravel on our road surfaces that was caught in a mud deposit and is now being exposed by weathering ?
It looks as if these blueberries are stuck to the rock because the RAT has ground away the surface and there are blueberries half embedded in the rock. So... what does this mean? Does it mean that there are two types blue ones and normal coloured ones and are they ALL stuck to the rock? (This would explain why they dont get blown about at all and would explain why they dont occur in the 'channels' between rocks) These channels have looked to me as if there is flowing water very recently but if these blueberries are attached to the rocks, then they will not collect in piles or between rocks.
Just in case this link gets lost in the forum, this picture is a good example of some 'hairs' 'growing' from the spherules. If you zoom in and look carefully, quite a number have these and I suggest they are spores from fungi starting to sprout. Ignore the 'thingy' in the picture for the moment as it is the subject of another thread here No holes in spherules that I can see though there are other signs of tiny life in this one.
As you can see from some of my other posts, I am a believer in 'the borrowers' a race of tiny people(on Mars, not on Earth). This is because there have been images where there is evidence of very small structures or cities.
IF (and its a big 'if') this is true, then these spherules could be mined or used for food for these small beings. That would be one far-fetched explanation for the perfectly round holes. Another would be boring insects/beings too.
I agree, weathering does not make sense here.
So, if it is not wind or rain, what other natural process does that leave the scientists to explain this phenomena?
Well if you saw some of these on Earth, what would you expect caused them? What about inhospitable Mercury (Although you wouldn't find these there, but that's irrelevant. Just a method of devising an explanation)?
I don't really like the erosion idea, but that's just me. It certainly isn't wind erosion, but it could be from some other cause. The thing is, we don't know much about what is going on at this scale on Mars, and thus we should not jump to any premature conclusions.
I did a quick Google search. It appears that when we see this on Earth, it is either the result of volcanism or burrowing organisms.
There aren't enough holes in these rocks to make me take the volcanism idea seriously.

In this picture there are at least 3 spherules, blueberries or whatever you want to call them with holes in them. This means that the holes are either caused by erosion (in which case the hole would not have a clean just-drilled look as one of these has) or the hole could be made by a bug of some kind boring into the spherule, or it could be where the spherule has broken off from the 'thing' it grew on.
Erosion is generally caused by wind, or water mixing with the atmosphere to form some kind of weak acids which eat away at the rock. This is possible on Mars as there is some moisture but it would not give a clean hole like this.
Only the erosion-caused explanation would stand up to scientific scrutiny because there are supposed to be no bugs on Mars, and there are supposed to be no plants on Mars either. So what made these holes?
I realise that the rock with the perfectly-formed hole is not necessarily a 'spherule' or blueberry but nevertheless, it is still strange to have such a perfect hole. What could have made it?
