On October 4, 1957, the Soviet Union succeeded decisively in flying the first artificial satellite, Sputnik 1, into the space orbit of Earth. This had made the USSR the first nation to travel in space. The successful orbit of Sputnik was achieved with rocket R-7 with modifications on them.
In fact, Sputnik 1 itself was basically a polished metal ball (58 centimeters in diameter). It had basic radio transmitters which produced a unique beeping sound. This beacon indicated to the global observers that it was operational and in its orbit.
The major task of the satellite was to send radio pulses to analyze the atmosphere. The ability to achieve the placement of objects in stable orbit was indicated with its successful release. These possibilities were far reaching other than just the scientific research.
The launch of Sputnik left no doubt that the Space Age had started. It introduced competition in space exploration and development of technologies across the globe. This achievement was the only one of its kind that made the Soviet Union achieve its status in history.
Conclusion:
On October 4, 1957, the Soviet Union released the initial man-made satellite, Sputnik 1. This occasion was a direct start of the Space Age as it showed that it was possible to fly in orbit. It made the USSR the first on the planet to be a leader in space. The success of Sputnik forever changed human technology.
