The sputnik marked the start of the space era, when it was launched in October 1957. Sputnik is simply the Russian word for satellite.
In August 29, 1949 USSR tested it first nuclear bomb, but lacked a way to deliver it
to targets in USA. While US airforce had strategic bombers placed on airbases all around USSR. The Soviet air force did not have any planes, that was capable of reaching US targets and
In 1955 first the USA and later the Soviet announced their plans to launch a satellite as part of the International Geophysical Year. In USA work started on the ill-fated vanguard project.
In USSR a scientific team started to work on a 1,0- 1,4 ton satellite packed with all kind of scientific
equipment. While the R-7 missile was ready for testing, the development of the large satellite
(later known as sputnik 3) was far behind schedule – and in the end Korolev decided that the rocket team should design their own smaller satellite (sputnik 1).
Today satellites is a major part of your life – for example broadcast of television, making reliable weather forecasts and
GPS. At same time we have been to the moon and a working together at the
ISS. The sputnik started it all.
