Topic description:
Space research is the scientific study of outer space, celestial bodies, and cosmic phenomena. Satellites, space probes, and telescopes gather data on the structure, origin, and behavior of the universe. Its goals include understanding cosmic evolution and the physical laws that govern the cosmos. The field is also a starting point for many terrestrial technological innovations. It combines fundamental science with engineering challenges, linking many disciplines from data collection to mission planning. New discoveries expand astronomical knowledge while shaping Earth observation and everyday technology.
