For all the children:
The Wonderful World of Disney TV show, on NBC, did a multi-part series, some live action, a lot animated, on the future of space exploration back in the mid-fifties. Wehrner Von Braun was the advisor. That ring thingie hanging in the background was an orbital space station. They explained how the "canals" on Mars were probably vine-like plants... In other words, 75% of the predictions missed by miles, and the rest was Von Braun's knowledge of what was on the NASA drawing boards.
I want to say it was three parts, but that was fifty years ago, and I'd have to look it up.
