What a dumbass. If we send people in the quickest possible way (or any way at all, really) and they all die in the attempt, that will set the whole project back decades.
The answer to the radiation problem is better shielding, not a fundamentally unsafe mission.
btw it is not the nuclear propulsion that I'm calling unsafe. It is the idea that we could do without redundancy. That's just a monumentally stupid idea.
Since the astronauts need water to survive, why not line the spaceship with reservoirs of it to provide the shielding? Or does water not block space radiation well enough?
But then they’re drinking irradiated water, no?
Unless it’s really easy to remove the radiation safely, this doesn’t seem like the right solution.
You wouldn't want to drink reactor coolant water (mostly because of the chemistry additives) but water in a tank that just stays between the people and the hot stuff would mostly just get warm.
Most of what you'd get at that kind of distance is neutrons, and they are more likely to bounce off the hydrogen than to do something like activate the oxygen into N16 which dies off pretty fast anyway.
