Asteroid mining first - we will need processing and refinement infrastructure in space, to start building facilities that aren't in earth orbit, so they don't pose radioactive threats. It's thought that there is a lot of uranium and other nuclear fuels available in asteroids throughout the solar system.

Once asteroid mining kicks off, all sorts of possibilities open up that are overly expensive or dangerous for earth based enterprises.

Totally. I wonder about turning larger asteroid(s) into colonies/ships themselves. There’s one large one that already orbits between mars and the outer planets with a sizable radius. I wonder about hollowing it out and building essentially a large city in its interior.

Edit-I think it’s 1036 Ganymed.

We just need to crack longevity, space elevators, and asteroid mining. A lot of the engineering for in system spaceflight is engineered already.

With ever improving automation, belt mining probably won't ever be a human occupation in the way 20th century sci-fi envisioned, but living in space is looking like it will be very safe. We'll need lots of water shielding, massive engines and this massive ships, and deliberate regimented exercise and medical monitoring. We'll have to incorporate massive redundancies in environment and nutrition and waste processing, so long term high output nuclear will likely be the only option.

I'm excited to see the birth of space mining in the next decade or three.
