The last humans to step foot on the moon, the crew of Apollo 17, did so in 1972. So far, no one has gone back…

It’s been 50 years though.

How do you explain this fact despite the undeniable scientific and technological advances ?

I would like to collect here as many opinions, hypotheses and if possible evidence on this subject as possible.

All opinions (rational or not) are welcome but try to respect those of others. (no judgement) ✌
