The myth that ‘no one owns the sky’ has been dispelled a long time ago, on October 4th, 1957 when the Soviets launched the first satellite to orbit the space, the Sputnik 1.
Since then governments and private corporations filled the space with an outstanding number of satellites that reached 4,987 active satellites in 2019 according to the United Nations Office for Outer Space Affairs (UNOOSA), an increase of 2.68% compared to the previous year.
There are several uses for satellites orbiting the space, those include communication, earth observational, navigation, weather, astronomical, and biosatellites.
