Oh and on FF drives, fhey’re kind of messy and risk pollution if they fail near earth (though not nearly as much as other nuclear designs). It’s fine for scientific missions, but becomes much more eyebrow raising en masse for a Mars colonization type effort.
IIRC the fissile material needs to be relatively high grade.
I don’t know if I quite agree with that being a morale issue. But that same logic nuclear reactors are immoral because if they blow up they can cause a lot of harm.
I do agree that it is a little sketchy for human flight, but they wouldn’t use it if there was a significant chance of it harming the people on board.
