>>18499423>Dust clouds in a vacuumfirstly, the animation in american moon which shows how the producers believe wheel-thrown dust would behave in a vacuum is completely unrealistic. no wheel could ever throw multiple dust particles in an exactly identical trajectory, as suggested by the animation. random factors would give each particle a different trajectory, causing cloud-like dispersion.
secondly, it is very obvious from the lunar footage that these "clouds" actually dissipate very quickly, before the rover has moved more than about a meter. this could not be more different to the picture the producers show of a rally car on earth with dust clouds hundreds of meters behind it. the dust particles on the moon clearly begin to fall as soon as they have reached the highest point of their trajectory, failing to linger or drift as they would on earth.
i's interesting to note that every single time the producers of american moon freeze-frame the lunar footage and circle a dust cloud, they select dust which was still on an upward trajectory, or had only just reached the top of its trajectory, at the point when the footage was frozen. they never circle a cloud which has remained at the same height for any amount of time, because there aren't any. and they never explain why they have to freeze the footage to highlight the clouds. If their theory was correct, and the dust clouds were lingering, they shouldn't have had to freeze the footage to highlight them. they should have been able to highlight clouds in moving footage.
