A subreddit to make space colonization a reality.. We have a very liberal interpretation of that goal so feel free to contribute anything that moves the conversation forward!
Discuss ways of making space colonization a reality and meet people who share your interest in space! Feel free to post about any projects or articles relating to space colonization. We also welcome self-posts containing questions or opinions open for discussion. Don't forget to check out our reading list or the dual subreddit of Space Colonization and Settlement.

Since mining task will require drilling onto the surface of the moon anyway, doing the task in such way so that leftover holes could be utilized for habitats would be beneficial
Main idea is to get a natural protection against perhaps around half of the radiation as habitat would be surrounded by thick ice from 5 sides
Front window panel from outside to inside would be made of 5mm borosilicate against micrometeorite protection, 1.5cm leaded glass for radiation , then anti-uv & ir reflective film
The "walls" seen there would be 20cm thick closed cell foam that enlarges off when sprayed. Copilot calculated so that there would need to be 750kg material needed for 20cm thick foam for 5 sides for 5m x 5m x 5m cubical space. Foam would be sprayed in heated form such as 60-70 degrees celcius onto the cold icy wall for chemical reaction to begin easier
Surface of the closed cell foam walls are sprayed with ir reflective paint. Tv stand to get a laser tv projector, behind the vision there would be kitchen & bathroom areas. Kitchen counters made of lightweight foldable counters
There would be a half-cut second floor area for bed, storage, desk, where sitting area below and entirity of the front glass panel would be visible, so you would stretch in your bed with a nice jupiter view in front of you when you wake up i suppose
These habitats could be built in a vertical line on a ridge surface so that it would give an apartment-like vibe, where the most bottom drilled area could be utilized as greenhouse area, generating food while recycling O2, water, connected to habitats above it. This type of settlement wouldnt occupy space on natural flat surfaces around where they could be utilized for mobility or other purposes
Guys you seem to know a lot about space so you should know every planet has a different type of rain so could there be a planet where ITS RAINING TACOS OUT IN THE STREETS TACOS ALL YOU CAN EAT
Does anyone know of any international meetings geared to space colonization, besides Mars Society? I'd like to meet other folks who are interested in off-planet, O'Neill Cylinder colonization
I have been doing bit of a deep dive in space colonization, speculating how far our ingenuity might actually take us. I have been interested in the Kardesheve Scale ever since I was 16 and put hours into consuming any information regarding it. I understand that Type 3 is the maximum power usage that Kardesheve predicted, but now I see a lot of people talking about Type 4, Type 5, and even Type Omega. I find that this kind of speculation is starting to get ridiculous, hence why I started looking for more realistic (but still theoretical) scenarios, and so far I think Type 2 is the most likely outcome, believing that concepts such as the Dyson Sphere and the Caplan Thruster are possible. We might colonize exoplanets from the comfort of our solar system, sending generation ships as we pass by neighboring stars, even though we might not be able to ever communicate with them again once they reach a certain distance due to the speed of light being the fastest that information can travel, it's also the reason that I don't think a Galactic Federation can happen. Not only would a galaxy-wide organization be too big to reasonably manage, but the speed of light would make it impossible for all star systems to cooperate. Even though FTL methods such as the Alcubierre Drive and Wormholes are technically possible, they require exotic resources that do not exist in our universe and could probably break causality. Even if a Galactic Federation was possible, would it really be necessary? Think about it, does one power really to occupy and control that many worlds? If we managed to only ever populate just the entire Solar System, I think that would be enough for humanity because it would be much easier to manage than a galaxy and the farthest celestial body in the Solar System, Pluto, is only 5.5 light hours, which is a more tolerable communication distance compared to Proxima B. Even though we might be confined to our solar system, we can still explore and populate the galaxy, despite not being able to form any practical, real-time communication with those systems. That is just what I like to believe, I would like to hear what you think. Do you agree/disagree? Do you believe we might develop FTL? What's your prediction?
I'm sure this has been discussed here before, but seems a worthy topic.
In my opinion, this is the most important goal for the survival of our civilization, but frustratingly remote to our lives in 2024.
What can we do?
Hi All - I'm new here. Does anyone else feel like massive space habitats are the only hope for our civilization?

I sketch a particular design for an O'Neill cylinder that might be within reach for modern governments. Let me know what you think!
Even if the design isn't to your liking, the appendix has some math on O'neill cylinders that I couldn't find anywhere else!
