In 1957, the USSR made history by launching the world's first man-made satellite into orbit. This groundbreaking achievement was known as Sputnik 1. Sputnik 1 was a spherical satellite with four long antennas, and it weighed about 184 pounds. It was launched into space on October 4, 1957, from the Baikonur Cosmodrome in Kazakhstan. The launch of Sputnik 1 marked the beginning of the space age and the start of the space race between the United States and the Soviet Union. The successful launch of Sputnik 1 had a significant impact on the world. It demonstrated the Soviet Union's technological capabilities and sparked fear in the United States that they were falling behind in the space race. This led to an increased focus on space exploration and the eventual landing of humans on the moon. Sputnik 1 transmitted a simple radio signal that could be received on Earth, allowing scientists to track its orbit and study the Earth's upper atmosphere. The satellite orbited the Earth for about three months before its batteries died, and it burned up upon re-entering the Earth's atmosphere. The launch of Sputnik 1 paved the way for future space exploration and the development of satellite technology. It also inspired a new generation of scientists and engineers to push the boundaries of what was possible in space.
