I have a bit of knowledge concerning transport of sediments by both wind and water carriers. (I will also preface this by saying that I have not done
an extensive amount of research specifically on Mars, so am not an expert on it).
However, considering that a large number of very knowledgeable geologists have examined these structures not just from telescopes but from closer
orbital photographs and deemed that they are water erosive structures, and have maintained this for the better part of 30 years, I would stick with
I agree with WOS, wind erosive structures do make some very interesting and surprisingly geometeric structures, they are totally different and much
more chaotic than water erosive structures.
Combine with this the fact that everyone seems to forget about Mars atmospheric pressure: 1/100 earth atmospheric pressure. Even considering the
approximate 1/6 gravity of Mars, due to very low pressure, the wind cannot pick up near the density of sediment for extended transport that happens on
earth. Considering that most wind erosion occurs due to impact from wind blown debris, I find extreme wind erosion to be unlikely on Mars.
I also agree with FoxStriker, that this is likely at least in part disinformation: It is my knowledge that manned missions have at least been
attempted to Mars.... there is something there that the general public is not meant to know.
