Why?
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.
Calm down, he was answering “how fast could we get there”. It was never meant to be a realistic time frame.
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?
You would need a pretty good thickness of water and it becomes complicated shipping it up into space.
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.
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.
They used the ice for everything, including cooling and heating the ship as needed. They got the bad effects from the cosmic radiation pinging in from all other directions, not from using the water. The volume of ice was larger than that of the ship, I think it also absorbed physical damage from micrometeorites. Let’s hope someone in the Big Green Machine reads the novel.
I mean, they put nuclear waste at the bottom of miles deep water wells, because it absorbs alpha, gamma and beta particles and it’s cheap.
I don’t think it works that way. The water slows down the neutrons so that when and if they get to you they don’t have enough energy to hurt you. The radiation doesn’t contaminate the water any more than a microwave oven does.
“remove” what exactly? water is not alive so it’s okay to irradiate it https://en.wikipedia.org/wiki/Food_irradiation
Dude…wut.
Can’t tell if you’re joking or not.
.
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?
