1. Material support and space station support:

○ Tianzhou-9 has delivered a large amount of materials to the space station, including astronauts' living materials, scientific experimental equipment, etc., to support the normal operation of the space station and the advancement of scientific experiments.

2. Technology improvement and capability expansion:

○ The spacecraft has improved its cargo loading and emergency launch capabilities, and can better meet the needs of complex missions.

○ It supports multiple configuration states to meet the needs of different missions and improve the efficiency and flexibility of the spacecraft.

3. Scientific experiments and research:

○ It carries a number of scientific experimental payloads, providing a platform for on-orbit experiments of space technology and promoting research progress in materials science, life medicine and other fields.

4. Rendezvous and docking technology:

○ The 3-hour rapid rendezvous and docking mode is adopted to improve mission efficiency and become a normalized operation. The maturity of this technology will contribute to the efficient operation of future space stations.

5. Safety and security:

○ With the "double insurance" mechanism of emergency launch capability and material transportation, the safety and reliability of space station operations are improved.

6. Development of aerospace engineering:

○ It marks that China's manned space program has entered the stage of space station application and development, laying a solid foundation for subsequent missions.

The successful launch of Tianzhou-9 not only enhances China's position in the international aerospace field, but also opens up broader prospects for future space exploration.
