Space exploration is the investigation of outer space through the use of spacecraft, satellites, and other technologies. It encompasses a wide range of activities aimed at understanding celestial phenomena, planetary systems, and the universe as a whole. This includes missions to other planets, moons, asteroids, and comets, as well as human spaceflight and robotic explorations. The goals of space exploration are to gather scientific data, search for extraterrestrial life, study the origins of the universe, and advance technology. It often involves collaboration among various countries and organizations, leading to international efforts such as the International Space Station (ISS) and various space missions conducted by NASA, ESA, and other space agencies.
