created so that the Soviet Union can beat the usa in the race to be the first country to launch a satellite into space.
The Soviet Union, by the scientist Sergei Korolev
No one. Only some electronics.
There was more than one Sputnik. Sputnik was a common name for vehicles in the early Russian / Soviet Space programme, Sputnik 1, Sputnik 2 etc They were all invented by the Russians AKA Soviet Union. The team, at least for the first Sputniks, was lead by Sergei Korolev
Sputnik 1 made about 15 orbits per day
It means it was the first sputnik.
Sputnik 1 was a Russian satellite.
Sputnik was the "family name" for a series of satellites, so there never was a satellite named only Sputnik. They all had numbers with Sputnik 1 being the first.
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.
Sputnik 1 Sputnik 1
the name of the first satellite is Sputnik
Sputnik 1 and Sputnik 2 were artificial satellites that traveled around the Earth. People thought that Sputnik 1 was spying on them, but all it did was transmit a simple tracking signal for 3 weeks.
The US didn't launch the Sputnik, any of them. The sputniks, with Sputnik 1 being the most famous, was launched by Soviet Union, the USSR. Or the Russians if you wish.Sputnik wasn't American it was Russian. It was launched Oct. 4, 1957. It weighed 184 pounds and a month later they sent a larger satellite in orbit that was 1120 pounds and it carried a dog. By Feb. 5, 1961 32 American satellites were in space.
