Because america and Russia were 'competing' to see who could put the first man-made object into space. Russia launched Sputnik 1 - beating the americans.
Not much really. It's main purpose was to see if things could be launched into orbit and if they would remain functional up there.
Sputnik was also scientifically valuable. The density of the upper atmosphere could be deduced from its drag on the orbit, and the propagation of its radio signals gave information about the ionosphere.
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- if something could be built to keep operating up there- to show off what the then Soviet Union could do- oh, and it kept sending a beep on radio, so that people all over the world could hear it on their radio sets as it passed above.
No, the Russian's Sputnik was unmanned.

Sputnik 1 didn't have any cany camera or crew onboard, so it didn't see a thing.
Sputnik 1 made about 15 orbits per day

No, it was far too crude to have any value as a spy satellite. Basically it was an experiment to see if things could be launched into orbit and made to function there.
Because the Sputnik program ended with Sputnik 3. Albeit there was a Sputnik 40 and 41 but these were to commemorate the 40th anniversary of Sputnik 1.
