Space missions involve sending spacecraft or satellites into space to explore, study, or conduct experiments in outer space. These missions can be carried out by government space agencies such as NASA, ESA, or Roscosmos, as well as private companies like SpaceX or Blue Origin. Space missions can be categorized into various types, including manned missions (with astronauts onboard), robotic missions (unmanned spacecraft), planetary missions (exploring other planets), astronomical missions (studying celestial bodies), and Earth observation missions (monitoring the Earth's environment). Space missions have led to numerous advancements in science and technology, such as the discovery of new planets, moons, and other celestial phenomena, as well as the development of new technologies for space exploration. These missions also play a crucial role in expanding our understanding of the universe and our place within it.
