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?
They did that in the novel "Seveneves", used a massive chunk of ice as the bow of their ship on a one-way, twenty year plus trip. It didn't stop all the radiation, though. Just enough to keep a minimum number of crew alive to complete their mission. They all developed different types of cancers, anyways,but the kinds that could be treated along the way and extend their chances.
