When was the space satellite invented?
The first serious proposal was made by Athur C. Clarke in 1945. Although famous as a science fiction writer, Clarke was a radio engineer by trade. When WW2 ended Clarke was able to think about things other than the secret work of the war. He published an article in the fall of 1945 in the British magazine Wireless World. In this he proposed not just the launch of an artificial satellite, but its use as a com-sat. He even saw far enough into the future to propose a geo-stationary orbit containing a direct broadcast satellite.
Nobody seemed to take any notice for a long time. Then, with the approach of the International Geophysical Year, the US proposed the launch of MOUSE (Minimum Orbiting Un-manned Satellite Earth) in 1958. Most people thought this too was science fiction.
However, in the fall of 1957 the USSR stunned the world by launching the first satellite.
There are now so many objects in earth-orbit that space junk is posing a threat to new launches.
