Aerospace agencies are organizations responsible for the research, development, and management of activities related to aviation and space exploration. They work on projects that involve designing aircraft, launching satellites, and conducting scientific research in space. Notable examples include the National Aeronautics and Space Administration (NASA) in the United States and the European Space Agency (ESA). These agencies collaborate with various stakeholders, including governments, private companies, and international organizations, to advance technology and knowledge in the aerospace field. They also focus on safety regulations, environmental impacts, and the development of new technologies to improve air travel and space missions.
