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.
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.
Sputnik 2, launched November 3, 1957. Sputnik 1 was the first man-made Earth satellite, and Sputnik 2 was the second. Sputnik 2 carried a dog, Laika, as the first astronaut. The dog died a few hours after launch. The USA did not launch its first satellite, Explorer 1, until about 3 months later, on January 31, 1958.
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
Yes, Sputnik 1 orbited the Earth over 1000 times
Laika was sent into space aboard Sputnik 2.
Sputnik-2
They were unmanned, although Sputnik 2 carried a dog into space.
Sputnik 1 only housed some electronics, while Sputnik 2 held a dog called Laika.
That was Sputnik 1 launched 4. oktober 1957 I suppose the name was "Sputnik" and then later when they sendt the next one, they became "Sputnik 1" and "Sputnik 2" regards.
If they can put a satellite in orbit they can launch a H-bomb at us too. It wasn't quite true with Sputnik 1, but it was with Sputnik 2.
We cried.
Sputnik 1 was launched on the 4th of October, 1957. The booster used by it had been used in August of that year to launch a long range missile.
It means it was the first sputnik.
the 2 in Sputnik 2 means it is the second to be built.
Sputnik 1, 2 and 3 were all launched by the Sputnik rocket, a derivative of the R-7 Semyorka ICBM (NATO reporting name: SS-6 Sapwood).
Sputnik 1 was a Russian satellite.
Not as far as anyone knows. The next launch, Sputnik 2, carried a dog called Laika.
