Shenzhou-12 manned mission has four characteristics, and the re-entry module will land at Dongfeng landing site for the first time

Xinhua News Agency Jiuquan, Gansu Province, June 16 (reporter Huangming, Liyun) China Manned Space Engineering Office Assistant Ji Qiming in the morning of the 16th briefing introduced, as China's space station stage of the first manned flight, Shenzhou 12 manned mission to start, is very critical. In general, shenzhou-12 manned mission has four characteristics, which will lay a solid foundation for the construction and application of the follow-up space station and accumulate valuable experience.

First, the functional performance of the manned earth and earth transportation system will be further verified. The improved Long March 2 F-12 rocket has improved its reliability and safety; Shenzhou 12 manned spacecraft has added autonomous rapid rendezvous and docking, radial rendezvous and docking and 180 day in orbit docking capacity, improved the return technology, further improved the precision of landing point, and will also enable the manned spacecraft emergency rescue task mode for the first time. Second, the long-term support technology of astronauts will be fully verified. Through the crew of Shenzhou 12, they have been working and living in orbit for 3 months, and the support technologies of long-term space flight of astronauts such as regeneration life insurance, material supply of space station, and astronaut health management are examined and verified. Third, the ability of astronauts and manipulator to complete the out of cabin activities and operation outside the cabin will be verified on orbit. The astronauts will carry out the long-term out activities for the first time with the support of the mechanical arm, and carry out the operation operations such as equipment installation, maintenance and other operations outside the cabin. Fourth, the search and recovery capacity of Dongfeng landing site will be tested for the first time. The landing site was adjusted from Siziwang Banner in Inner Mongolia to Dongfeng landing site, and the first time, the normal emergency standby search and rescue mode of landing site system was started.

According to the space station construction mission plan, 11 missions will be carried out in the next two years, including three space station cabin launches, four cargo ships and four manned spacecraft launches, completion of the space station in orbit construction in 2022, and the completion of the national space laboratory, which will enter the applicable and development stage. The 11 tasks are closely related and linked. Recently, the successful launch of the sky and core cabin and the tianzhou-2 cargo ship have formed a combination of in orbit operation. Shenzhou 12 manned spacecraft will be rendezvous and docking with the core module after it is launched into orbit.

Ji said that during the implementation of Shenzhou 12, the centenary of the party coincided with the centenary of the party. The whole project focused on drawing lessons from the history of the Communist Party of China, especially from the brilliant process of China's space industry construction and development under the leadership of the Communist Party of China. All the participants are putting in various preparations with high mental state.
