Sputnik was the first artificial Earth satellite, launched by the Soviet Union on October 4, 1957. It marked the beginning of the space age and the U.S.-Soviet space race. The satellite transmitted radio signals that could be received on Earth, capturing global attention and demonstrating the capabilities of space technology. Its successful launch had significant implications for science, technology, and geopolitics during the Cold War era.
Sputnik did not launch from the moon, and it did not land on the moon.

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.
