Yes, both were launched from the Baikonur Cosmodrome.
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.
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.
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.
We cried.
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.
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.
Sputnik 1, launched on October 4, 1957, was the first artificial satellite to orbit the Earth, transmitting radio signals back to Earth. In contrast, Sputnik 2, launched on November 3, 1957, carried the first living creature into space, a dog named Laika, and included more advanced instrumentation for scientific research. While Sputnik 1 was primarily a demonstration of satellite technology, Sputnik 2 aimed to study the biological effects of space travel on living organisms. Additionally, Sputnik 2 was significantly heavier and larger than its predecessor.
It means it was the first sputnik.
the 2 in Sputnik 2 means it is the second to be built.
