Doubt it. I’d say the physical and mental rigours would require high levels of certain ‘born with’ traits. A quick, analytical mind that can function under pressure, natural strength and stamina, great eye sight, lack of anything relating to vertigo, very high spacial awareness, zero claustrophobia etc.
On claustrophobia, I read that one of the early NASA missions (can’t remember which one) was the equivalent of sitting in the front of a VW Beetle with your mate, wearing a bulky suit and helmet- for two weeks. I think I’d go insane.
