Saw this, https://www.syfy.com/syfywire/astrophysicist-believes-in-megasatellite-habitats-around-ceres Some scientist says its better to build a string of stations around Ceres than to colonize the Moon or Mars. I don't agree, we might get out there eventually, but why go so far? We can build stations in earth orbit, probably in the Lagrange points, Ala Gundam and other shows. Bring asteroids/comets to those Lagrange points as supply material, but the idea of going ALL the way out there is just stupid at this point. Now, say in 100 years ( realistic, we thought we'd have moon colonies by 2001 in the 60's.. yeah.. was going to say 50 years, but our malaise lately on space travel just stretches timelines) we might have some colony's in the asteroid field for people that are out there mining asteroids, or seting them up to be de orbited to an Earth orbit for materials. By that time maybe have some better options of propulsion for in system flight. So, to me out next step from a small moon colony, which unless we get some gravity technology will only be a temporary place to visit, would be rotating space colonies in Earth orbit. Could start with a Stanford Tarus, with the eventuall goal of a large O'neill cylinder ( open or closed). As the population keeps ticking up, we need SOMETHING to off load some people. Thoughts??
