Let's say we already colonized some of the planets and moons in our solar system. Mars,Moon, Europa and etc. Planets like Mars and other has less gravity than earth, so the resource needed for space travel in our solar system will reduce by a lot if we launch spaceships there. Say, that we already can do asteroid minings by 2030. How long will it take for humans to colonize planets in other solar system?
