You seem to forget that NASA actually landed on the Moon as far back as 50 years ago, had SIX missions land on the moon awith 12 astronauts walking on the moon and has been studying the Moon for as long as there has been a NASA and even before that.
You talk like NAS doesn't know anything about the moon. They know pretty much everything about the Mona that they need to know in order to establish a Gateway to the Moon and a base on the moon itself.
The Earth is protected by magnetic fields that protect the planet. The moon has no such protection.
Now why don't we go back to Sir Isaac Newton's equation for gravity which has three variables; masses of two objects, the distance between them, and force F itself; which we called gravity along with gravitation constant G.
And that equation is
F = Gm1m2/r2
It does not matter how apart things are, gravitation force of any objects always exist, that force never goes to zero.
The Space Station is below and is protected by much of the Earth's magnetic field.
These are astronauts on the Space Station:. Oh wait, they are floating.
