Your brother will be interested to read Hubble Shoots the Moon ...

Except, of course, that it's from NASA and therefore everything is a lie including "the" and "and". Even assuming that, though, anybody with an elementary knowledge of telescope optics can compute the angular resolution of an instrument the size of Hubble ... and then convert that to a GSD at the distance of Moon. Then, he could compare that GSD to the (alleged) size of the lunar landers ... and then realize that he's on a fool's errand. He's gonna need a bigger telescope.

The Apollo descent stages left on the lunar surface are too small to be seen by Hubble, which can see objects as small as 60-75 yards, about three-quarters the length of a soccer field. The left-behind descent stages are only about the size of a small truck.

These observations weren't easy. The moon is a difficult target for Hubble because it moves across the sky faster than Hubble can track it and is very dim in ultraviolet light. The observations required steady, precise, as well as long exposures to search for the resources. In spite of these challenges, Hubble was able to image all of its targets, and early results show that Hubble can detect ilmenite at the Apollo 17 site from 248,000 miles (400,000 km) away.
