There are a lot of (now historic) landing sites on the moon. You can see a great review of them in this answer to the question How many extraterrestrial bodies have hosted a “lander” which returned images?
One is actually an historic re-visit to a previous lander. For more on that see How did Apollo-12 manage to land next to Surveyor-3? First “Space-Tourists”? and answers therein.
I remember something about a proposed "small sat" mission to the Moon to photograph some of them from orbit and transmit the images back to earth, "verifying" that they are real with (even more) photographic evidence. I believe it was proposed on a Russian analog to Kickstarter or the like. I think there was some discussion in this site, something about encryption and validation, but I can't find it now.
And I think one of the participants in the now-expired X-prize competition had proposed a rover to do something similar. But I don't keep up.
Question: (What happened to the) Plans to visit and/or document sites of previous lunar landings? Are any active now?
