Wernher von Braun begins the film Challenge of Outer Space by saying, "The conquest of outer space is the greatest technological challenge of the age in which we live."
Even before a manned mission to the moon the nation's top space scientists were speculating about what space stations would look like. I find it difficult to mentally put myself in an era when space exploration had not yet occurred, but films like this help a great deal.
The torodial space colony is featured heavily in the film and is a favorite among those depicting space stations of the future.
Above is a short clip of the 30 minute film and I hope to explore Challenges of Outer Space in depth as more information about this paleo-futuristic wonder becomes available.
