Countries and Their First Satellites

The launch of the Soviet Union’s Sputnik 1 satellite on October 4, 1957, marked the beginning of the Space Age. Sputnik 1 was a small, 58-centimeter-diameter aluminum sphere that weighed 83.6 kilograms. It contained four radio antennas and batteries, and it orbited the Earth every 96 minutes. Sputnik’s launch was a major technological achievement, and it came as a shock to many people in the United States, who had hoped that their country would be the first to launch a satellite.

The United States responded to Sputnik’s launch by launching its own satellite, Explorer 1, on January 31, 1958. Explorer 1 was the first satellite to detect the Van Allen radiation belts, which are two regions of high-energy particles that surround the Earth.

In the years since the launch of Sputnik 1, many countries have launched their own satellites. Here is a list of countries and their first satellites:
