You won’t find this on YouTube:
The Hidden Earth is one of many films made available by the Laboratory for Atmospheric and Space Physics at the University of Colorado.
The films presented were produced after the International Geophysical Year (IGY) in 1957-58 by the National Academy of Sciences. They use footage taken during the IGY field research, and “each film focuses on one of the thirteen research themes of IGY.”
See the National Academy of Sciences’ site for more examples of their IGY-related educational outreach efforts.
