IGY! Science and the Vanguard Satellite in 1959 (video)

The International Geophysical Year (1958-1959) was a very scientifically productive period.  It is really amazing how much we learned from tiny satellites like Vanguard.  Like the shape of the Earth!  Great stuff in this video.  

Very cool telescopes and cameras set up around the world to monitor the early satellites.  And there is a quick mention of ham radio efforts to monitor the new spacecraft. 

Thanks to Josh G3MOT for sending this to us. 

Go IGY!
