Shooting the moon...

Ok recently it was posted on here that the VLT was going to use its 8meter scopes to attempt to spot the lunar landers...

Ok if my math is correct an 8 meter scope could resolve features of ~30 meters on the moon (assuming 500nm light)... are they going to link their scopes interferometrically to get the better resolution? They will CERTAINLY have to use adaptive optics, but adaptive optics requires a star like point very near your obseving target... (I have only heard of one AO pic taken of the moon- their "starlike point" was a montain on the terminator that only had its peak illuminated... rather a fortuitous event....)

So assuming they are only using one scope, and are lucky enough to get a "star like point" close to the landing site they still cant resolve the landers- The best they could manage is to see its shadow and maybe the soil disturbed by the astronauts.....

Now, the reason I bring this up is at Keck they have a 10m primary mirror and also the advantage that they have a laser guide star system that lets us put a star like point almost anywhere they want...

With a resolution of 20-30 meters on the moons surface could you see enough to see evidence of the landers? (like shadow, disturbed dirt etc....?)

Hee-Hee I sound like Dr. Evil now... "I want to shoot the moon with my 'laser'"
