Yesterday was the 56th anniversary of the launch of the Sputnik 1, the first artificial satellite build by people from the blue planet. The video below was made in 1957 and is what you would see in the news of the week, if were alive when it happened.
Despite just being a ball of almost 60 centimeters (or 23 inches), its success was the start of the Space Race between the Soviet Union and USA, that lead the man to arrive on the Moon in 1969 and the development of many technologies that are part of life today.
The Sputnik 1 signal could be detected by any amateur radio of the planet and it inspired two students of Physics from USA to imagine a way to use this signal do find the relative location of the satellite within the orbit. This idea not only worked, it also lead to the development of the first global positioning system, known as TRANSIT, that was later replaced by today’s GPS.
There are yet many other consequences in human level caused by the Sputnik 1 that are really hard to calculate, like kids that were inspired by this event to become scientists, writers and more.
