 - 1. Space exploration is the investigation and study of outer space by means of space technology. It encompasses the discovery and exploration of celestial bodies such as planets, moons, asteroids, and comets. The goal of space exploration is to learn more about the universe, our place in it, and the possibility of life beyond Earth. This pursuit involves both manned missions, such as sending astronauts to the International Space Station, and unmanned missions, including probes and rovers sent to explore distant worlds.
