Concept- The first artificial satellite sent by Russia is Sputnik I. The Soviet Union created and launched the first man-made satellite into orbit. It was the biggest achievement of the scientific community on the planet. Space exploration began with the launch of artificial satellites by several governments.
Sputnik I was the Soviet Union's first artificial satellite launch.
It was also the first man-made object to sail through space. The successful launch of the satellite into orbit was Russia's biggest source of pride. It was first introduced on October 4, 1957.
For three weeks, the satellite remained in one of Earth's lowest orbits. In the meanwhile, the battery expired, and the first mission was a success given the technology available in the twentieth century.
The satellite was a 58-centimetre-diameter spherical body.
The satellite's launch provided a vast amount of data on the upper atmosphere. The drag encountered by the satellite throughout its journey aided in determining the density of the atmosphere at various heights. The mission also provided clear concepts about the route, orbits, and other characteristics necessary for space flight, assisting in the validation of theoretical values.
The mission provided valuable information for future space exploration.
Because of this achievement, several countries, including India (Aryabhata in 1975) , became enthused about space initiatives.
Hence, the correct answer is Sputnik I .
