The aerospace system consists of aircraft, launch vehicles, spacecraft, and ground support facilities, forming a system for the transfer of materials and information between heaven and earth. Aircraft include civil airliners, cargo planes, fighter jets, and others, and their aerodynamic layout design enables intra-atmospheric transportation. Launch vehicles, as space transportation vehicles, use multi-stage propulsion systems to deliver spacecraft into their intended orbits. Their guidance systems rely on ground-based tracking and control stations for real-time corrections via radio signals. Spacecraft include communications satellites, remote sensing satellites, and manned spacecraft, carrying specialized payloads to perform specific missions. Their on-orbit operation relies on uplink commands from the ground control system.
