What did Sputnik do?

Answer 1

Sputnik satellites were a series of space vehicles sent up into space by the Soviets. Sputnik 1 was the first artificial satellite, sent up in October 1957, really just to test the feasibility of a man made satellite. Sputnik 1 stayed in low orbit around the earth for 3 months before re-entering and burning up through the earths atmosphere. Further Sputnik vehicles took animals and men into space, or took probes to Venus and Mars.

There were several Sputniks, with Sputnik 1 being the most famous.

Sputnik 1 wasn't really meant to do much, it was mainly an experiment to see if:

- something could be launched into space and achieve orbit

- to show off what the then Soviet Union could do
