In a vacuum or near-vacuum, you don't get a "cloud" that causes the atmosphere to slow and disperse dust. The moon is not quite a vacuum, but it's close. are actually suspended in air to a notable degree by the mass of the air. Think back to your junior high school science class, when they demonstrated how a feather and a marble fall at the same rate in a vacuum.
Gravity alone would cause matter to behave quite differently on the moon with its 1/6 gravity of Earth. Why can a man's boot kick the dust on the moon and it only fall a few inches in front of him? Wouldn't the dirt fly 6 times the distance it would have on Earth? Also if a man can kick the dirt so easily why isn't there even a little bit of dirt on the landing gear? Why if sped up 2x does the video look like a man moving in regular gravity? What about the lunar rover, wouldn't there be a cloud of dust a dirt taking 6x the length of time to fall to the ground?
