Zhang Bonan, deputy to the National People's Congress, deputy chief designer of China's manned space engineering and chief designer of the optical module system of the space station of the Fifth Academy of Aerospace Science and technology group, revealed yesterday that in 2022, China's manned space station project will enter the construction stage of the space station, complete six major tasks, including the sky inquiry experimental module, the dreamsky experimental module, the Shenzhou manned spacecraft and the Tianzhou cargo spacecraft, and fully complete the space station, The first flight of six spacecraft combinations was realized, the first astronauts stayed for six months, and the first two crew of six astronauts were in orbit at the same time. China's manned space project was officially approved by the central government on September 21, 1992. The manned spaceship system, cargo spaceship system, space laboratory system, space station system and optical module system in the manned spaceflight project are all developed by the Fifth Academy of Aerospace Science and technology group. Space station mission planning includes three stages: key technology verification, construction and operation. Zhang Zhongyang, member of the National Committee of the Chinese people's Political Consultative Conference and general manager of Aerospace Science and technology group, said that the verification stage of key technologies of China's space station will be basically completed in 2021, and five launch missions will be a complete success. The Tianhe core module was successfully launched, and the on orbit assembly and construction of the space station were carried out in an all-round way. The tianzhou-2 cargo spacecraft was launched into orbit and docked with the Tianhe core module for the first time, completing the transportation of extravehicular space suits and astronauts' consumables. The mission of Shenzhou 12 achieved the entry and safe return of Nie Haisheng, Liu Boming and Tang Hongbo, the first astronauts of the space station. The tianzhou-3 cargo spacecraft was launched into orbit to complete the transportation of follow-up astronauts and materials. The first radial rendezvous and docking of manned spacecraft was realized on Shenzhou 13, and the second batch of astronauts Zhai Zhigang, Wang Yaping and ye Guangfu of the space station were stationed for a long-term stay of six months. "It is expected that in April this year, the Shenzhou 13 astronaut crew will return after staying for six months. After that, China will conduct a comprehensive evaluation of the verification of key technologies of the space station. After the results meet the requirements, it will move to the construction stage." Zhang Bonan told reporters that in the construction stage, China will launch six spacecraft, including Tianzhou 4, Shenzhou 14, Wentian experimental module, Mengtian experimental module, Tianzhou 5 and Shenzhou 15, to complete the rendezvous, docking and transposition of Wentian experimental module, Mengtian experimental module and core module in manned state, and finally complete the construction of T-shaped space station; After the completion of construction, the functional performance shall be tested in orbit, and then transferred to the operation stage. He also revealed that in 2022, the manned spacecraft will return as planned, two rendezvous and docking, and three emergency rescue standby ships, involving four Shenzhou spacecraft from Shenzhou 13 to Shenzhou 16. At the same time, the ground research and development of Shenzhou 17 and Shenzhou 18 will be carried out in parallel. (Xinhua News Agency)
