Top 10 Space Agencies in the World | 2021
While most space-related researches are conducted by astronomers with ground-based telescopes, physical exploration is carried out by both human spaceflight and unmanned robotic space probes.
The main purpose of space exploration is advancing scientific research, uniting different countries, and ensuring the survival of humanity for a long period of time.
The early era of exploring space (the 1950s) was driven by a ‘Space Race’ between the United States and the Soviet Union. Today, many nations have their own space agencies working under certain rules and policies.
In particular, more than 70 government space organizations and tons of private companies are currently engaged in activities related to space research. A few of them are far ahead of others, in terms of achievement, capabilities, and annual budget.
