They are the nexus of many tasks. Weather prediction, navigation, broadcasting.
The first satellite in space was Sputnik 1 which means as a word fellow traveller was send in 1950 by Russians. After 7 years, the first biological spacecraft that called Sputnik 2 was sent by carrying a terrier female dog. By the following year, 1958, Sputnik 3 has taken its place in space as a first launched orbit. In the same year, 1958, America also started to launch the orbits. The satellite Score has become the world’s first communication satellite.

“Nothing is harder to image than the past. It is imperative that all Landsat observations are archived and made available to users.”
Bound of Literature – Science fiction and Satellites
Arthur C. Clark was the first known author who talks about artificial satellites before the satellites were sent to space. Clarke was a science writer, futurist and scuba diver. He was an avid populariser of space travel. Clarke contributed to the popularity of the idea that geostationary satellites would be ideal telecommunications relays.
