Hi there, I'd like to connect with people to discuss technical aspects of settlement of mars.
I'd look at a house on earth and ask: what things have to be supplied from the outside; what things can be produced inside the house? Houses on earth have piping for water, and cabling for electricity.
Plants can be grown in a green-house using these two ingredients, and the people can sleep in a spaceship.
Comment whatever comes to your mind.
How do they currently do it on space stations?
the current attempt seems to be that ISS is low enough to be protected by earth's magnetic shield (which, as I understand it, only protects against particle radiation, not EM radiation). So that would stop most radiation from hitting the ISS and astronauts. So the radiation dose is a bit lower than in true (even-farther-out) outer space, and then pray for the best, basically.
Edit: Ok, now I'm thoroughly confused. Multiple sources contradict one another about what kind of radiation is actually most prevalent in outer space. Most say it's particle radiation (which would be easy to protect against), but some say it's electromagnetic radiation, which would be way more problematic.
