Over the years, Disney has done some of the best educational work ever assembled, translating complex concepts about science and history into forms we can all easily understand. This is one of my all time favorites from that collection, a story about the history of space science, and how we came to understand how it works. Mind, Disney did nothing about resolving the scientific questions, but it sure explained them so we all understood, and gave us a fun little animation to watch while doing so. I like it a lot, and appreciate the education it has given so many, including me.
