The space age was ushered in 55 years ago today (4 October 1957) with the launch of the satellite Sputnik-1. My favourite quote on Sputnik:
“Nobody back then was thinking about the magnitude of what was going on: everyone did his own job, living through its disappointments and joys.” -Oleg Ivanovsky, deputy designer for Sputnik
