Space missions refer to scientific expeditions, exploration, or operations conducted in outer space. These missions are typically carried out by space agencies, such as NASA and ESA, and involve sending spacecraft or satellites into space to study celestial bodies, gather scientific data, or conduct experiments. Space missions can vary in scope and objectives, ranging from studying the planets in our solar system to exploring distant galaxies and black holes. Some missions are focused on understanding the origins of the universe, while others are aimed at developing technologies for future space travel. Space missions are typically complex and require careful planning, coordination, and execution. They often involve collaboration between multiple countries and organizations and can take years to prepare and carry out. Overall, space missions play a crucial role in expanding our knowledge of the universe and advancing space exploration technology.
