Taking the Russian method of ownership, we have planted a flag on the moon therefore it is ours and any nation entering our “lunar space” will be thusly charged with treaspassing, spying, espionage, and possibly and act of war.
That was my understanding. We were there FIRST! planted our flag and established ownership. We also launched several Apollo missions afterwards, have equipment on the moon sending data.
Anyone else sending stuff to the moon should have to ask permission, pay rent, etc..
