It would depend on how big the crash site is but I doubt any ground-based optical observatory could resolve such a site. A ground-based optical telescope, at the very minimum, would need a 100-meter diameter optical primary mirror to just barely resolve the Apollo landing sites and we don't have any of those yet.
Unfortunately, or perhaps fortunately, the laws of physics do put a lot of constraints on things despite what you might read on the internet - or on PW threads.
