Space feat: China's manned space flight sets an amazing record!

China's manned space program has successfully launched another mission, this time the Shenzhou-17 manned spacecraft, marking the perfect end of the 2023 launch mission in the application and development stage of China's space station. As a "special train" for Chinese astronauts, the Chang-2F rocket plays an important role in ensuring the safe entry of astronauts into space. In this launch mission, there are a total of 25 technical status changes of the Chang-2F rocket, involving design improvement, process optimization and plan refinement, which further improves the reliability and safety of the rocket. Wei Wei, director of the overall design office of the overall design department of the rocket institute, said that at present, the process of the launch site of the Chang-2F rocket has been compressed from 49 days in the initial stage of the construction of the space station to 35 days, and now it is aiming at the 30-day goal to continue to optimize in order to better meet the needs of the space station application and development stage. It has been 20 years since China's first manned spacecraft, Shenzhou 5, China's manned space launch has achieved 30 battles and 30 victories, and China's "magic arrow" is more stable and stronger. The success of this launch mission means that China's space industry has taken another step forward, and we look forward to more achievements in manned spaceflight.

Since 2003, the Chang-2F rocket has undergone many improvements and upgrades, not only in terms of safety and stability, but also in terms of comfort. However, during the first manned flight, astronaut Yang Liwei felt an uncomfortable vibration, known as POGO vibration. In order to solve this problem, researchers quickly carried out data analysis and improvement, and this vibration phenomenon completely disappeared in the subsequent missions such as Shenzhou 6 and Shenzhou 7. The astronauts were very satisfied with the comfort of the Chang-2F rocket, and even said that they could hardly feel the vibration during the flight, which was very comfortable. At present, China is developing a new generation of manned launch vehicle, the Long March 10, which is expected to make its first flight in 2027. The payload capacity of the new rocket will be increased by about three times, and in the future it will carry a variety of samples for space biological experiments. The Shenzhou-17 manned spacecraft will be the second manned spacecraft in the application and development stage of China's space station, carrying out the 12th manned space mission. As the "boat of life" for astronauts to travel back and forth between heaven and earth, the Shenzhou spacecraft has extremely high requirements for reliability and safety, with 14 subsystems.

All in all, China's space industry has made tremendous progress and development in the past 20 years, continuously improving the safety, stability and comfort of manned flights. The future Long March 10 rocket will further enhance the mainland's space capabilities. What kind of achievements do you think China's space industry can achieve in the future? The Shenzhou-17 manned spacecraft was successfully launched, and the forward rendezvous and docking with the space station were completed, and three astronauts were stationed in the core module of the space station. The mission is scheduled to dock for up to six months, during which a number of space missions will be carried out, including astronaut out-of-cabin activities and cargo airlock out-of-cabin missions, space science experiments and technical tests, platform management, astronaut support related work, and popular science education. In addition, the Shenzhou-17 manned spacecraft also carries the experimental unit of the "Space Protein Molecular Assembly and Application Research" project, which contains a total of 5 research contents, which will carry out the preparation of single crystals of proteins/nucleic acids and their small molecule complexes, further study the effects of space microgravity environment and radiation and other factors on molecular structure and crystal structure, biological function, pharmacodynamics and pharmacology, etc., and guide the safe use of drugs in space and the design and development of ground drugs.

The mission included not only Chinese astronauts, but also a variety of experimental samples, including insulin, cancer therapeutic protein complexes, key proteins for plant photosynthesis, and more, with the aim of contributing to human health. About 8 hours before the launch, these experimental samples were placed in biological sample cargo packages and sent to the launch tower, where they were launched with the spacecraft. The experiment will also study the effects of the space environment on molecular structure and biological functions to guide the safe use of drugs in space and the design and development of drugs on the ground. After the Shenzhou-17 spacecraft completed the rendezvous and docking with the space station, the astronauts transferred the above-mentioned experimental sample units to the space station module, and carried out relevant scientific experiments according to the mission plan. In addition to these, China's commercial aerospace industry has also actively participated in the manned space project, and released the results of the preliminary selection of the proposal for the development of a manned lunar rover. This indicates that China has begun to think about the future direction of aerospace and strengthens the country's strength and influence in the aerospace field. In short, the successful launch of Shenzhou-17 marks a new stage in China's manned spaceflight. From the stationing of astronauts on the space station, to experimental sample space science experiments, to the development of commercial spaceflight, China has made significant progress in the field of aerospace.

The road to space in the future is still long, but China will always be guided by innovation and practice, constantly break through itself, and become an important force in the international space field.

It is reported that after expert review, the China Manned Space Engineering Office finally selected the plans of six teams and entered the detailed design stage of the program. These schemes have been recognized in terms of advancement, engineering feasibility and research foundation, and have received engineering support. Among them, the joint plan of the Eighth Academy of China Aerospace Science and Technology Corporation with China FAW, Northern Vehicle Research Institute, Beijing Institute of Technology, and Huizhou EVE Lithium Energy Team, as well as the joint plan of the Fifth Academy of China Aerospace Science and Technology Corporation, Guangzhou Automobile Group, and the Hong Kong Polytechnic University, are considered to have obvious advantages. They will follow the program to deepen research, focusing on the innovative design of the manned lunar rover and the development of individual advantageous technologies.

In addition to these proposals, the teams from Tsinghua University, Beihang University, Chongqing University and Shanghai Jiao Tong University have submitted their own unique proposals in cooperation with relevant institutions and enterprises. Although they have advantages in some individual technologies, they have not received engineering support after expert evaluation, but will still be subject to follow-up research. In addition, in terms of the low-cost cargo transportation system of China's space station, a total of 9 units submitted 10 proposals that meet the requirements. Through expert evaluation, 4 units received engineering support and entered the detailed design stage of the scheme. Among these schemes, a number of units have adopted the rocket solutions of private commercial space rocket companies, which are developing rockets with high comprehensive cost performance, and are expected to participate in subsequent rocket commercial procurement and carry out the launch mission of low-cost cargo transport vehicles on the space station. Generally speaking, China's manned space program has entered the critical stage of detailed program design, which will inject new vitality into the development of China's space industry. Through cooperation with different units and enterprises, China's innovation capability in the aerospace field will be further enhanced. It is believed that in the near future, we will usher in a new milestone in China's aerospace industry.
