NASA's Space Colony Designs From the '70s 90
New submitter oag2 writes "Discover Magazine has a new slideshow of NASA's pie-in-the-sky (or, rather, toroid-in-the-sky) mock-ups of what space colonies would look like, complete with verdant mountains, flowing rivers, cocktail parties, and a guy on a floating bicycle. Though the designs are retro-futuristic, the artist who made them was prescient in other ways. From the accompanying article: "In the context of the 70s, when we had some sense of momentum from Apollo as far as expanding the human presence in space, it seemed like the kind of thing we could have just picked up and moved with," Davis says. "And it's still possible. It's just a matter of where we decide to spend our money." But Guidice remembers a more telling prophecy from O'Neill. "One of the most memorable things I ever heard him say was, 'If we don't do it right now,' meaning in the next 20 years, and that was 20 years ago, 'then we'll never do it, because we'll be overpopulated and the strain on the natural resources will be the number one priority. We will not have any sort of inclination to see this through."'"
The O'Neill referenced above is Gerard K. O'Neill, physicist and founder of the Space Studies Institute. He wrote a book in 1976 called The High Frontier which featured these mock-up paintings, and explained in great detail how the space habitats would function. It's a fascinating book, and well worth reading if the pictures pique your curiosity.

Ah, yes, "The High Frontier". Back when NASA thought they could build a shuttle that didn't cost $600 million per flight. The plan was to set up a big moon colony first, mine the moon, build a big catapult, and launch materials from the moon to a Kevlar "catcher" in Earth orbit. (What could possibly go wrong?)
The 1952 Colliers/Von Braun space program [wikipedia.org], with its plans for a big wheel-type space station from which Moon and Mars missions would be launched, was more realistic. What killed it was the Apollo "Man/Moon/Decade" goal. That was achieved, but with technologies useful for little else.
NASA still thinks that way. Their Mars Direct [nasa.gov] program would have sent a manned mission to Mars as a one-shot mission.
Space travel with chemical rockets is just too inefficient for big projects in space. Fusion still doesn't work. Fission would work but is rather messy. None of the big fancy hypersonic space plane things really work. (Remember Reagan's hypersonic space plane scheme? Ben Rich, head of Lockheed's Skunk Works and designer of the SR-71's powerplant, refused to bid on that. "We used titanium (on the SR-71). You know of something stronger?")
