During which decade were satellites first sent into orbit? 1940s 1950s 1960s 1970s

The second alternative is correct (B).

Satellites are equipment that, after being launched into space, remains in orbit around the Earth. These equipments have become fundamental to use technologies on Earth, such as mapping, communication and tracking.

The first satellite was put into orbit by the former Soviet Union in 1957. The Sputnik I had mass of approximately 83 kg and had no specific function, only transmitted a signal from a radio. The technology evolved, was launched by other countries and today there are specific satellites for television, meteorology, communication, etc.
