Can you provide the trajectory of the moon dust that was kicked up by the Lunar Module thrusters to show that it would have reversed direction so it could coat the landing pods?Imagine how much moon dust would have been kicked up by the Lunar Module truster as it landed. The lander must have been covered by moon dust. Certainly those landing pods would have been covered in dust, right.
No, this does not settle anything, since the trajectory of the dust in the video was changed by the atmosphere of the earth and the moon does not have any atmosphere to change the trajectory of the dust.Your responses take up a lot of space so let me get to the main point.
As to the the claim there was very little dust kicked up by the moon lander and all the dust neatly settled leaving no visible disturbance.

I guess this settles this issue, right?

But, your mention of moon dust does bring up one of the many proofs that we landed on the moon.
Proof we landed on the Moon is in the dust The key is the trajectory of the dust as it flies up behind the lunar rover. Because the dust in the images is so fine it was impossible to track any individual grains. Instead, they used the top of the dust cloud as their marker. Tracking the movement of the dust cloud clearly shows characteristic rooster tails and not the simple parabolic arc of a dust cloud we would see produced by a rover driving through, say, dust on Earth. This specific rooster tail shape is contingent on the lunar environment: the initial velocity of dust particles based on the rover’s speed, the gravitational field strength that is one-sixth what we have on Earth, and the complete lack of air resistance because the Moon has no appreciable atmosphere. Turning this visual data in to formulas allowed Hsu and Horányi to plot the movement of dust on a graph, turning the Grand Prix’s rooster tails into a mathematical visualization. So here’s where this gets really interesting. Hsu and Horányi didn’t stop after tracing the movement of lunar dust particles. They used the same formulas to plot the trajectories of dust particles on Earth, taking into account air resistance. And because air resistance affects particles of difference sizes so drastically, they took two values for their Earthly dust for good measure. The two scientists plotted the movement of four particles on one graph, two in a lunar environment (the solid lines) and two in an Earthly environment (the dotted lines). The graph shows that in any environment the particles begin with the same initial velocity but their ballistic paths are very different. Air resistance on Earth drags particles down fairly quickly whereas on the Moon the lack of air resistance gives particles a longer trajectory. |
