Is there any telescope on Earth that can see the lunar rovers on the moon? If I have the right numbers, it seems to me that even Hubble telescope might barely be able to make out a carcass of a blue whale on the surface of the moon, which puts objects as small as the lunar rovers or the American flag left there by Apollo out of range. Hubble is often lauded as the best telescope we have built. I know a large part of that is because it is in space where it's free from all of the interference of the atmosphere, but is there any ground-based observatory with better resolution? Is there any place on Earth where I could point a scope at the Sea of Tranquility and see what we left there over 40 years ago?
The largest optical wavelength telescope that we have now is the Keck
  Telscope in Hawaii which is 10 meters in diameter. The Hubble Space
  Telescope is only 2.4 meters in diameter.
  
  Resolving the larger lunar rover (which has a length of 3.1 meters)
  would require a telescope 75 meters in diameter.

Update: In a comment to my answer, @Envite mentions Astronomical Interferometers which are:


  ...an array of telescopes or mirror segments acting together to probe
  structures with higher resolution by means of interferometry. The
  benefit of the interferometer is that the angular resolution of the
  instrument is nearly that of a telescope with the same aperture as a
  single large instrument encompassing all of the individual
  photon-collecting sub-components. 


It also must be noted that probably this wouldn't be the best idea for watching the moon rovers since:


  The drawback is that it does not
  collect as many photons as a large instrument of that size. Thus it is
  mainly useful for fine resolution of the more luminous astronomical
  objects, such as close binary stars.
