Your shot simply has wetter/darker sand under foot. Irrelevant. There are circumstances where this occurs and they are not even remotely suspicious or deserving of a scientist's attention.
Posts #258 and #259 please. But try to actually address the post - maybe watch what is being presented this time eh?
#258 itself points to a big messy post. Make a clear point here, and I'll address.
#259 - your "coincidence" argument holds some weight. 3x, same behavior. It addresses the "scuttling sand hit's HIGH point", weakening that claim of a "high point".
For 3 cases, we have a "chaotic launch of dust at various velocities (direction and speed)" - producing a very similar result. This doesn't mean that "the sand was all projected upwards at the SAME speed as Cernan's center-of-mass"... If sand was projected with an upwards angle (which likely was) -- we're talking Apples to Oranges. You can only compare projectiles with the same starting vertical velocity.
With an atmosphere, the wind-resistance impact on dust is greater than it is on Cernan too, which would have impact on the fall time.
So your argument here combats the likeliness of a "high point" playing a role on "scuttling sand". So if you want to call this a "smoking gun that there wasn't a high-point on the ground to block scuttling sand", be my guest. I'll consider that to be a compelling argument, against the "high point" theory -- and as a result, I won't propose the "high point" hypothesis again, because your argument makes it evident that this "high point" hypothesis is unlikely.
However, it does NOT remove the ambiguity involved in trying to decipher whether or not this was on the moon or earth -- based upon these videos.
