raised a concern that the thick dust layer at the top of the regolith would not support the weight of the lunar module and that the module might sink beneath the surface. However, Joseph Veverka (also of Cornell) pointed out that Gold had miscalculated the depth of the overlying dust, which was only a couple of centimeters thick.


a couple = 2

2 cm = 0.787402 inches

I did find this , and if this is correct, then a close approximation
of the weight of the surface dust can be found.

note: these figures are associated with moon atmosphere.
I'm going to assume that they are considering the moon dust as being the atmosphere , I might be wrong.

Abundance at surface: 2 x 10^5 particles/cm3

Estimated Composition (particles per cubic cm):
Helium 4 (4He) - 40,000 ; Neon 20 (20Ne) - 40,000 ; Hydrogen (H2) - 35,000
Argon 40 (40Ar) - 30,000 ; Neon 22 (22Ne) - 5,000 ; Argon 36 (36Ar) - 2,000
Methane - 1000 ; Ammonia - 1000 ; Carbon Dioxide (CO2) - 1000
Trace Oxygen (O+), Aluminum (Al+), Silicon (Si+)
Possible Phosphorus (P+), Sodium (Na+), Magnesium (Mg+)


thats 155,000 particles per cu cm excluding the trace particles , which must include the other 50,000 particles given
that the Abundance at surface is 2 x 10^5 particles/cm3.

200,000 particles

the dust feels like snow , and it smells like a fresh battlefield.








3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
