China News Agency, Beijing, February 9th (Ma Shuisha) The press conference of the "Blue Book of China's Aerospace Science and Technology Activities (2021)" was held in Beijing on the 9th.

The reporter learned from the meeting that the Shenzhou 13 manned spacecraft will adopt the rapid return plan for the first time, and plans to perform the return mission in mid-April.

  The mission planning of the Chinese space station includes three stages, the key technology verification stage, the construction stage and the operation stage, and is currently in the key technology verification stage.

Berlin Hou, deputy chief designer of the space station system of the Fifth Academy of China Aerospace Science and Technology Corporation, said that after the Shenzhou 13 astronaut crew stayed in orbit for 6 months and returned to the ground in April this year, the scientific research team will conduct a comprehensive evaluation of the verification of key technologies of the space station. , after the results meet the requirements, the space station will be transferred to the construction stage.

  "In the construction phase, six spacecraft, Tianzhou-4, Shenzhou-14, Experimental Module I and Experimental Module II, as well as Tianzhou-5 and Shenzhou-15, will be launched in sequence, and Experimental Module I and Experimental Module II will be completed in a manned state. The rendezvous and docking with the core module, and the repositioning, finally completes the construction of the T-shaped space station; after the construction is completed, the functional performance is tested on-orbit, and then transferred to the operation stage." Berlin Hou said.

  Talking about the mission characteristics of China's space station in 2022, Berlin Hou said that the tasks are interlocking and highly coupled; the spacecraft has been docked and separated many times on-orbit, the state of the assembly is complex, and management is difficult; , the status of tasks such as cargo out of the cabin is new.

  In addition, Shao Limin, deputy technical manager of the manned spacecraft system project of the Fifth Academy of China Aerospace Science and Technology Corporation, introduced the mission arrangement of the manned spacecraft in 2022.

He said that after the Shenzhou 13 manned spacecraft completed the longest six-month combined docking mission so far, it plans to perform a return mission in mid-April, using a rapid return plan to land at the Dongfeng Landing Site.

After the launch of Shenzhou 14, it will cooperate with the space station to complete the rendezvous, docking, and transposition tasks of the Wentian experimental module and the Mengtian experimental module, as well as the assembly and construction tasks of the space station.

  Shao Limin said that after the launch of Shenzhou 15, the Chinese space station will dock two manned spacecraft for the first time, realizing the rotation of the 6 astronaut crews in orbit. At the same time, the Shenzhou 16 manned spacecraft will be on standby at the launch site as an emergency rescue ship.

  This year, the Chinese space station mission will achieve several firsts.

Shao Limin pointed out that for the first time, Shenzhou 13 will complete the docking mission of a combination of up to 6 months, and implement a rapid return for the first time, which will further improve the comfort of astronauts and the efficiency of mission implementation; Shenzhou 14 and Shenzhou 15 will carry The human spacecraft docked at the space station at the same time, forming a 6-cabin combination configuration for the first time. Through the crew rotation method, a mission state of uninterrupted manned presence in the space station was established.
