It showed that orbiting the Earth was feasible, a vital step towards escaping Earth's gravity. (I've assumed that you mean a man-made satellite, rather than our Moon, which is also a satellite of the Earth.)
The launch of the first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957 marked the beginning of the Space Race.
The launch of the Soviet satellite Sputnik in 1957 is often considered the event that sparked the space race between the US and Russia. This was the first artificial satellite to be put into Earth's orbit, signaling the beginning of the space age and prompting a sense of competition between the two superpowers.
Sputnik 1 was the first artificial satellite launched into space by the Soviet Union in 1957. It marked the beginning of the space age and the space race between the US and the Soviet Union during the Cold War.
The first artificial satellite into space was named sputnik and was launched by the USSR. The term "Space Race" actually applies to the race to the moon which was won by the US when the Apollo spacecraft touched down in 1969.
The first thing the Russians sent into space was the satellite Sputnik 1, launched on October 4, 1957. It was a landmark achievement as it marked the beginning of the space age and the start of the space race between the United States and the Soviet Union.

The Space Race began in the late 1950s between the United States and the Soviet Union. It was a competition to demonstrate technological superiority and achievements in space exploration. The launch of the Soviet satellite Sputnik 1 in 1957 marked the beginning of this rivalry.
Russia sent its first rocket into space on October 4, 1957, with the launch of the Sputnik 1 satellite. This event marked the beginning of the space age and the start of the space race between the United States and the Soviet Union.
The first satellite, Sputnik 1, was built by the Soviet Union and launched into space on October 4, 1957. It marked the beginning of the space age and the start of the space race between the United States and the Soviet Union.
Just getting a satellite into orbit.

Basically the Successful Launch of Sputnik I by then USSR started the Space race as US Space programme till then was not integrated and successful launch of SputnikI triggred 1)formation of NASA 2)passing of Space act by US congress 3)allocation of funds for the space projects.
The first Russian spacecraft in space was Sputnik 1, which was launched on October 4, 1957. It was the world's first artificial satellite and marked the beginning of the space race between the United States and the Soviet Union.
