Sputnik 1, launched by the Soviet Union in 1957, was the first artificial satellite to orbit the Earth. Its primary purpose was to demonstrate the feasibility of launching satellites into space and to gather data on the Earth's atmosphere and ionosphere. The satellite transmitted radio signals that could be received on Earth, providing valuable information about radio wave propagation and marking the beginning of the space age and the space race. Sputnik 1's success also spurred advancements in space technology and exploration.
