The Communist Party of China (CPC) people’s spiritual pedigree ｜ Manned space spirit： creating excellent results of launching ＂0 mistakes＂ and recycling ＂10 rings shooting＂ with hard work.

　　CCTV News:Just three days ago, our reporter met Yang Liwei. After the mission in Shenzhou 5, he, like other astronauts, has to do physical training for three and a half days every week. The astronaut team is divided into the main echelon and the backup echelon. As a member of the backup echelon, Yang Liwei mainly conducts special training for the tasks of the future Shenzhou 15 spacecraft. Yang Liwei, who is now the deputy chief designer of China’s manned spaceflight project, often talks with the astronauts on the Shenzhou 12 spacecraft.

　　In a recent call, the astronaut of Shenzhou 12 told Yang Liwei that the work in space was not easy.

　　The space station consists of Tianhe core cabin, two test cabins, Tianzhou cargo ship and shenzhou spaceship. In order to create a comfortable environment for astronauts, in 2020, the Fifth Academy of Aerospace Science and Technology Group organized a five-cabin joint test in Tianjin Aerospace City.

　　Tianhe core module was launched by Long March 5B rocket on April 29th this year. In this hall, there are too many ups and downs of the Long March 5 team. On July 2, 2017, the "Changwu" team suffered an unforgettable failure. Without any warning, when the rocket flew to 346 seconds, the engine parameters suddenly dropped, and the launch of the second rocket failed. In order to find out the cause of the launch failure, it took nearly 100 days for the "Changwu" team to locate the fault alone.

　　There are Cosmos 5, Delta 4 in the United States, Ariane 5 in Europe and H2A in Japan in the world. The success rate of the first flight of these four rockets is only 50%. In order to grasp the development law of large-scale cryogenic rocket, in the process of solving the remote 2 fault, the "Changwu" team gradually refined more than 5,000 design characteristics that affected the success or failure, and strictly controlled them with data one by one, finally ensuring the consistency of products.

　　After the successful launch of Yaoer II, the Long March 5 will be followed by the mission of the third phase of lunar exploration and the space station. "Changwu" people are faced with two choices: redesign and optimization. Redesign is simple and safe, but it will take another two years for the engine alone, which has unimaginable impact on major national projects. In the end, the "Changwu" people resolutely chose the road of optimization and improvement, even if they only sleep for four or five hours a day, they should solve the problem.

　　China has been catching up, running and surpassing all the way with amazing speed since the manned spaceflight project was implemented for 29 years. From the unmanned spacecraft to the stable operation of the space station, China has crossed the development course of developed countries for half a century, and 12 astronauts have made 17 in-orbit flights. With hard work and responsibility, astronauts have created outstanding achievements in launching "0 mistakes" and recovering "10 rings for shooting", and also injected new era connotation into the manned space spirit of "being particularly able to endure hardships, fighting, tackling key problems and contributing".
