The days and weeks leading up to the opening of Disneyland on July 15, 1955 consisted of a mad scramble to construct, paint and decorate the park before its television debut. At the same time, another massive operation was underway at the park - the preparation for one of the biggest live television events in the history of the relatively new medium.
On this date in 1955 the Man in Space episode of the Disneyland television show premiered on ABC. An estimated 42 million Americans tuned in to watch the first of three “science factual” programs Disney would air on the future of space exploration. The show, which is currently available to stream on Disney+, would influence the development of Tomorrowland as well as launch the public’s interest in space into a new orbit.
