Spacecraft manufacturing involves the design, construction, and testing of vehicles that travel beyond Earth's atmosphere. This process includes creating various components, such as the structure, propulsion systems, and electronics, which must all work together reliably in the harsh conditions of space. Engineers and technicians use advanced materials and technologies to ensure that spacecraft can withstand extreme temperatures, radiation, and vacuum. Once assembled, the spacecraft undergoes rigorous testing to confirm its performance and safety before being launched into orbit or on interplanetary missions.
