There's no earth-based telescope in existence that can resolve anthropogenic features on the moon. Only telescopes in lunar orbit can do that, today. (Technically, you can confirm the presence of the optical retroflector from earth, with a very sophisticated laser setup that's, I'd WAG, $100k+ of physics equipment. Far beyond "anyone can just look!" territory).
