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.
Your Mars house will need pressurization, and some sort of airlock if you're planning on coming and going.
Hmm yeah, airtight buildings are a challenge to construct.
That's why I've favored the people on Mars living in the spaceships. The building already exists, and is naturally air-tight (after all, it has been airtight for 6 months in outer space). But that has its downsides: less protection against radiation, mostly. (due to only having 5mm of steel and 200 kg/mยฒ CO2 above your head instead of meters full of dirt and rock.)
