In the field of aerospace, every rocket launch carries countless expectations and hard work from people. Looking back on 2023, China's aerospace history has added another glorious page: the Tianzhou-3 cargo spacecraft successfully lifted off, and the Shenzhou-12 spacecraft safely returned to its mother's embrace, becoming a remarkable moment in history.

The successful launch of Tianzhou-3 is thanks to the hard work of researchers and the collaborative efforts of the entire team. This achievement is not only a breakthrough in technology, but also a strong proof that China's aerospace industry is moving towards the world stage.

On the other hand, the safe return of Shenzhou 12 demonstrates the courage and resilience of Chinese astronauts. In the unknown environment of space, the handling of every small detail is crucial. The significant changes in the appearance of the spacecraft before and after launch are both a manifestation of technological progress and a focus on the safety of astronauts.

Around the Earth's orbit, spacecraft must maintain balance under thin air resistance while also overcoming the Earth's gravity, which is undoubtedly a highly challenging task. During the process of returning to Earth, including the start and separation of the engine, preparation for re-entry into the atmosphere, and other steps, each step requires precise calculations and operations.

At the moment of entering the atmosphere, the spacecraft will face extreme temperatures, so the use of heat resistant materials is crucial as they firmly safeguard the safety of astronauts.

In the final stage of landing, including the opening of the deceleration parachute, the start of the reverse thrust engine, and the final landing, all of these steps require the precise operation of astronauts and the tacit cooperation of the team, in order to ensure the safe landing of the spacecraft.

During the process of satellite return to Earth, there will also be many unique challenges and problems. For example, the phenomenon of combustion can only occur on planets with an atmosphere, so it is necessary to fully consider this in the design and planning of satellites.

Overall, the vigorous development of China's aerospace industry cannot be separated from the silently dedicated scientific researchers and the spirit of teamwork. Every success is the result of countless people's efforts and has laid a solid foundation for the future of China's aerospace industry.
