re: Fractal clumping of Mars Soil
I hate to sound like a novice, but then I am one:
The surface of Mars is subjected to plenty of solar radiation and obviously water is not present on the surface and if it was it would or is evaporating quickly. So, electromagnetism, maybe even static, comes to mind along with the surface matrix of these fines (after so many years of being exposed to such weathering).
So maybe that would explain "the stickiness" that they are referring to.
Yes, no?
