    Also, there have been a number of recent technology shows on TV here in the US about the "Space Race", that show that animation we may all be familiar with of the Sputnik separting from it's nose cone. It's interesting to note that there appears, in the animation, a puff of gas between the nose cone and the satellite body. I never noticed it before but is anyone familiar with the separation mechanism?
