Satellites are powerful communication and observation stations floating in space. Since the first space treaty was signed in 1967, thousands of satellites have been sent into space around the world. Their job is to receive any radio, television or internet signal sent from Earth and amplify it and relay or send it back to the other side of the world. Which keeps our daily lives moving. Since there is no wind or friction in space, it can go around the Earth for years without any additional fuel.
