I needed to create a space station.
I had a cast of characters, the makings of a plot, and a big-picture concept of how my universe had turned out as it did.
But now it was time to get down to creating the habitat space station on which my characters would live.
Where does one start?
One goes back to the 1970s, I discovered. That was the era when I first learned the concept of a “space station,” much less that people were seriously thinking about how one might actually build one someday.

I was a college kid when I went to a movie called Star Wars, for the scandalously high price of three dollars per ticket. My then-boyfriend Pascal (now husband of 37+ years) and I went back to see it over and over again, as often as we could afford to (pre-video tape–but then, I’ve already admitted I’m older than dirt).
I didn’t know it when I was bankrupting myself at the movie theater, but just a couple of years earlier a bunch of rocket scientists and other geniuses had gotten together at Stanford University for the 1975 NASA Summer Study, to try and figure out how it might be possible to build a space colony.
They came up with something the shape of a bicycle wheel, with mirrors mounted on the hub. Artificial gravity was to be created by centrifugal force inside the outer ring. Being scientists, they didn’t call it a doughnut or wheel-shape, but a torus. It is still known as the Stanford Torus.

According to Wikipedia’s article about the project, it was based on earlier ideas proposed by Wernher von Braun and Herman Potocnik. The concept was known to science fiction writers, but the scientists really got going on it in 1975.
The idea of using centrifugal force to create gravity in a wheel-like structure also was suggested in the 1957 Russian film, Road to the Stars, which is fascinating to watch. Indeed, we’re still speculating on some of the same things they did, and a lot of the speculation doesn’t seem to have changed all that much. The entire 49-minute opus is available for viewing on You Tube. If you have time, take a look.

If you look at the list of contributors to the 1975 Summer Study, it really did take a village to work out the myriad of details to arrive at something that might actually work. It’s now all freely available online.
Although it’s been used in many movies, from 2001: A Space Odyssey to Elysium, the “classic” Stanford Torus isn’t the only prototype space station shape from which the would-be sf author can choose, however. In upcoming posts from this “DIY Space Station” series, I’ll look at Bernal and Dyson Spheres, the O’Neill Cylinder, and Bishop Rings.
