Correction, missed by one diameter.
By the, The Moon is made of Green Cheeze, wait, that has been updated to Earth Rock, from when 4/5 of the crust was blown into space in an impact event, which happened sometime between 65,000,000 years ago, or Billions of years ago, and either way, the outward splater all rejoined into a ball, and hung around.
If either view is true, it is Earth Formed Rock.
I remember when they faked the Moon landing, claiming to put a retro rocket craft down in a sea of dust, and never raised a cloud in 1/6 gravity. If it had been a real Moon landing, the cloud would have hung for days, weeks, months? Maybe the wind blew it away. They are shown walking, hopping, through dust, that stays on the ground like good dust.
On a life critical mission, they brought their golf clubs.
2001 was a better movie.
