Space research involves the scientific study of outer space, including celestial bodies like planets, stars, and galaxies. It aims to understand the universe's origins, structure, and evolution. Researchers use telescopes, satellites, and space probes to gather data and conduct experiments beyond Earth's atmosphere. This field also includes the exploration of human spaceflight and the effects of space on the human body. Organizations like NASA and ESA lead many space research initiatives, contributing to advancements in technology and knowledge that can benefit life on Earth and inform future missions to other planets, such as Mars.
