Here is a very nice presentation of the russian built "Sputnik". As TED rightly describes "Soviet Union's launch of Sputnik in 1957 led to both the space race and the arms race -- and jump-started science and math education around the world". Its an interesting 4 minutes and if anything, you'll get a little bit of knowledge on how the space race jumped a gear.
