Uh....dudes....the mass of the Moon is too large for mining to have an impact on its orbit. Think about this....there are literally several thousands of man made satellites orbiting our Earth. Most will plummet into the Earth and get burned in the atmosphere, the rest will move further away. The Moons orbit will not be affect by us mining it.
And just FYI....the moon is moving slowly away from Earth. Has been for 3 billions of years. But look...it\'s still there.
Hey....this is romantic! We\'re all staring at the moon together!
