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?

Liquid and rockets is a death sentence.

Liquid and space vessels is worse.

Liquids on reentry is never going to happen.

Water doesn't have to be a liquid, but don't actual spacecraft typically contain liquids during wall of those cases? What do you mean?

You can freeze it before launch, but you'd have to freeze it again before reentry. Not possible, especially if you're talking about lining a craft with it during months of space travel. Water expands when frozen, and contracts when liquid. Metal does the opposite. How would you engineer that?

Didn't think I needed to stoop to that level. Thought I was talking to about obvious things and didn't want to sound patronizing.

Thanks for clearing that up.

Build the hypothetical ship in space and you never have to deal with it except as ice, which is easier to move around and shape into what you need. The ISS has a lot of liquids on board in all sorts of forms, from chicken soup, to ink pens, to the urine inside astronaut bladders. I don't understand what you're trying to say.

Do you even know what question you're responding to anymore? Wtf
