The spece program used terrain like moonscape in a lot of places to train. They extensively used a bunch of th so called “Canadian Shield near Sarnia, Ontario for training astronaughts, prototype dune buggies and other equipment. It was a big deal back then. A classmate, a surgeon treated many of their injuries, etc. No different from Patton using the Az and Southern California for training their oops in desert warfare. Does this mean the entire north African campaign was a fraud too?
Lots of places in the southern deserts resembling moonscape were used as well as some deep scuba training o try to simulate weightlessness and of course the Air Force transports with their parabolic arcs to create real weightlessness. Lots of this kind of research can be done via computer stuff here days, but believe it or not the whole Apollo program was guided by old fashioned slide rules, not computers.
I’m amazed there are still some holdouts actually believing it was all a farce and fraud! LOL.
