Today there are over 1000 active satellites in orbit (Union of Concerned Scientists 2017) and many times that number of defunct ones.

Sputnik 1 is shown above. It consisted of a shiny metal sphere, 58.5 cm in diameter, made out of an aluminium alloy. To the sphere were attached four radio aerials. Unlike later satellites, Sputnik 1 carried no scientific instruments and wasn’t fitted with a TV camera to take pictures. It had no solar cells to generate electricity and was powered by three non-rechargeable batteries. Its…
