Man in Space was broadcast on Disneyland March 9, 1955 (USA). It went on to have a 1956 comic book, a classroom text in 1959, and a theatrical release in 1956 alongside Davy Crockett and the River Pirates.
It was also released overseas. (see this rare 1958 Japanese advertisement)
So this is about the 2nd life of the film as a classroom documentary. As the Space Race began in earnest it was re-released and marketed to educators as a way to teach children about their future. to go along with this film was this rare classroom guide. It probably was intended to accompany their 1959 classroom books.
I have found guides for all 3 of the Disney space films and will share them through the rest of Feb. I know that you may already be familiar with the film but I really enjoy how they intended to engage students in learning about what they are seeing and preparing for their future.
These visionary questions are very interesting:
"After man reaches other planets, is it conceivable that people of Earth will be drawn closer together?"
"How likely is it that present barriers between nations will tend to break down as contacts with other planets develop?"
