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.
