astronautics
意味: The science and technology of space travel and exploration, encompassing the design, construction, and operation of spacecraft beyond the Earth's atmosphere.
Astronautics is the counterpart of aeronautics, dealing specifically with spaceflight rather than atmospheric flight. It covers orbital mechanics, rocket propulsion, life support systems, and mission planning. The field has grown rapidly since the mid-20th century and is central to discussions of satellite deployment, planetary exploration, and the emerging commercial space sector.
