Like i proposed before have a ozone layer in the shell of the ship. This would simulate the earths upper atmosphere and catch most of the radiation.

Better yet store the onboard water in a shell around the ship. As I recall from military training water is a great dampener of radiation

Water though has to be kept from Freezing, as the temps in space are more extreme than here on Earth, and the farther away from the suns warmth, the closer to absolute zero the temp can get, water expands when frozen too and frozen water isn't too usable for some tasks.

The ozone layer is a nice idea, however it would need to be tens of miles thick to do any good. Kind of makes the ship rather large I'd think.

Water is a excellent idea. We have to take it along anyway, so it can do double duty. I'd suspect we would have at least a double hull and perhaps a triple hull so micrometeorite damage could be contained and repaired. Putting the water next to the innermost hull would allow it to absorb some of the excess waste heat from the electronics, I doubt there would be need of heaters to keep it from freezing, more likely chillers to keep it cold.

The problem with a water jacket is that it can't 100% cover a space ship. There will be areas which won't have this protection. We can limit human exposure times in these spots, but once you have a hole there is always some angle that a particle can enter and reach any spot inside.

The item that will be needed is a large magnetic field around the ship. This will deflect the charged particles. Perhaps it would also allow them to be harvested along the way. But this still allows the uncharged particles and gamma radiation through.

All of this design talk is premature. We first need to send a few probes into interstellar space to measure the environment. If it turns out that it is too hostile for a man to be in a space suit doing an EVA to repair a hole in the hull, then it may turn out we can't leave the protection of Sol.

How true, It may be that We are in a very large prison, but hopefully this will not be the case.

Too bad we couldn't get the first 10 or 20 of the richest from Forbes' list to help in this cause. The older I get, the chance of me seeing anything exciting happening with the space program is slowly slipping away.

They want to see a profit, the higher the better, so good luck, maybe 1 or 2 might, but the rest, feet of cement...

The earths atmosphere has a miles thick Ozone layer. The ozone is thinly spaced over that area.

A spaceship could do the same job with a few inches of concentrated ozone.

What is old is new again ...
Back in the 'Nam era they gave conscripts their injections with guns that didn't use needles. Found they had a problem keeping the dang things clean. Got a few people sick, so they stopped using them.

THat's how they gave shots in 1983 before basic
