Vanguard 1 was launched 65 Years Ago And it blew up die to a stupid mistake. Of the eleven variants launched eight failed. I wouldn't be too proud of that. The Army got the Explorer-1 up on the first try.

My dad designed the Minitrack tracking system and the test vehicle satellites. The Vanguard proposal in 1955 was superior to the Army’s proposal in terms of its scientific uses. Originally vB didn’t have a radio tracking system for what became Explorer. https://www.youtube.com/watch?v=HS72o86aeZo
