The "Tiangong" space station embodies distinct Chinese characteristics and contemporary features. China's approach to space station development is pragmatic, emphasizing a balanced scale that aligns with the country's national conditions and actual requirements. Its key attributes include a high starting point, enhanced efficiency, cutting-edge technology, and robust security measures. According to Yang Hong, the chief designer of China's space station, while the station's size may be relatively smaller compared to the international space station, a comprehensive analysis of construction costs and practical benefits reveals a higher payload support efficiency. Furthermore, China's space station can be expanded as needed, incorporating an additional core module and two experimental modules, transforming from a "T"-shaped configuration to a "cruciform" configuration, effectively doubling its operational space. Notably, it serves as the world's first space "mothership," capable of in-orbit maintenance and co-orbital flight support for other spacecraft.
