Sputnik 1 was the first artificial satellite.

Sputnik 1 was launched into orbit around the Earth by the former Soviet Union on 4 October 1957. Since then, hundreds of artificial satellites have been launched, each with a different 【C3】______.
Some artificial satellites are used for telecommunication, which enable us to make telephone calls to any part of the world, to see 【C4】______ television transmissions and to communicate via the Internet. Other artificial satellites are used for navigation, so that people on Earth can know at any moment the position of an object, within a few meters. Others are weather or meteorological (气象的)satellites, launched to 【C5】______the state of the atmosphere and to follow the movement of the clouds as they gather. There are also military satellites, for the purpose of 【C6】______information on the armaments and the troops in countries which may be 【C7】______ and also to indicate the launch of a missile.

These are therefore controlled in such a way that they are 【C10】______ turned toward the Sun.
