What is the size of the smallest object on the Moon that can be seen by a 'scope on Earth or in Earth orbit?

WILL WE EVENUALLY ';SEE'; THE LUNAR LANDING BASE CRAFTS TO CONFIRM THEIR PRESENCE ON THE MOON? Thanks.What is the size of the smallest object on the Moon that can be seen by a 'scope on Earth or in Earth orbit?
Well we can currently ';see'; them by boucning lasers off of the reflecters left there, but as far as actually seeing the landers themselves? Nope. No telescope that we currentlyn have can come even close to it. As people send more things around the moon it would be quite possible that a future lunar orbiter would be able to image their location. We've done this with some of our probes on mars (imaged them from orbit, can't even come close from the earth).





Nit-picking edit:


CHARA won't be able to see anything on the moon. It is an intereferometer, and will measure spectral properties (wavelengths of light) with fairly high accuaracy. As an imager (full pictures) it won't do much.What is the size of the smallest object on the Moon that can be seen by a 'scope on Earth or in Earth orbit?
Depends on the telescope. (Its lens etc.)
The Hubble Space Telescope can resolve down to about 400 feet on the Moon's surface.





CHARA (Center for High Angular Resolution Astronomy telescope array, to be built) will have 330 times the resolution of Hubble. That would be enough to see the module.





But a way to confirm their presence on the moon right now is:
