50 years ago today, marked the beginning of the space age, with the launch of the first satellite, sputnik. it was only twice the size of a football ( a round one), and it emitted a signal that could be heard on a household radio as it circled the earth for 22 days.
this might not sound much now, with our iphones and internet connectivity, but back then a tv, and especially a colour tv was a luxury, and most people didn't have one, so the radio and the newspaper served as the medium by which the masses received their news. an aluminium object, twice the size of a football, sputnik changed the world forever.
