The satellite

Thousands of satellites circle the Earth. They convey TV transmissions, data traffic, mobile calls and tell our GPS precisely where we are. Even space stations, like ISS, are counted as satellites.

Sergej Koroljov was the man behind the world´s first satellite, Sputnik. When it was launched in 1957 it took the first step towards today´s advanced communication systems. It was also the starting signal for the space race between the USA and the Soviet Union.

A satellite maintains the same speed as the Earth, orbit after orbit. The Earth´s gravitational force pulls them downwards, but this is balanced by the centripetal force which makes an object follow a circular route. Since the forces are equal satellites remain in orbit around the Earth.
