From Gizmodo:
Back in the 1970s, a handful of artists drew up intricate renderings of said mind-bending super space stations for NASA. They make the International Space Station look like a flying tin can—which is essentially what it is. In these concepts, the space stations are big enough not only to support suburban-looking neighborhoods with houses and blonde-haired dudes in polo shirts but also entire farms with livestock and everything.
I hope that in my lifetime space colonies will become a reality. Like Carl Sagan once said to future space settlers, “Maybe we’re on Mars because of the magnificent science that can be done there – the gates of the wonder world are opening in our time. Maybe we’re on Mars because we have to be, because there’s a deep nomadic impulse built into us by the evolutionary process, we come after all, from hunter gatherers, and for 99.9% of our tenure on Earth we’ve been wanderers. And, the next place to wander to, is Mars. But whatever the reason you’re on Mars is, I’m glad you’re there. And I wish I was with you.”
