Astronautics is the science and technology of space travel and exploration. It encompasses the design, development, and operation of spacecraft and the systems that support human and robotic missions beyond Earth's atmosphere. Key figures in this field include Wernher von Braun and Yuri Gagarin, who have made significant contributions to our understanding of space. The field of astronautics not only involves launching vehicles into space but also includes the study of orbital mechanics, propulsion systems, and life support technologies. As we continue to explore the cosmos, astronautics plays a crucial role in advancing our knowledge and capabilities in space science and interplanetary travel.
