China News Service, April 17th. Hao Chun, director of the China Manned Space Engineering Office, introduced at the press conference on the 17th that the Shenzhou 13 crew flew in orbit for a total of 183 days, creating the longest continuous in-orbit flight time for Chinese astronauts. A long record, the complete success of the Shenzhou 13 mission marks the perfect conclusion of the key technology verification phase of the space station.

  Hao Chun said that yesterday, the Shenzhou 13 flight crew returned to the Dongfeng landing site safely and returned to Beijing in the afternoon.

At present, the three astronauts are in good health and are recovering after flight at the China Astronaut Research and Training Center.

  At the same time, Hao Chun reviewed the main process of the Shenzhou 13 mission: On October 16, 2021, the Shenzhou 13 manned spacecraft was launched at the Dongfeng Launch Site, docked with the core module of the space station, and 3 astronauts stationed in the core cabin.

During the astronauts in orbit, they took care and maintenance of the facilities and equipment of the space station as planned, carried out 2 out-of-vehicle activities, carried out space science experiments and technical experiments, and carried out a series of science popularization and education such as 2 "Tiangong Classroom" space lectures. Activity.

  Hao Chun said that the construction of China's space station is divided into two stages: key technology verification and construction, and six flight missions are planned respectively. Among them, the main task goal of the key technology verification stage is to comprehensively break through and master the key technologies related to the construction and operation of the space station.

Since 2020, it has successfully carried out the first flight of the Long March 5B carrier rocket, the Tianhe core module of the space station, the Shenzhou 12 and Shenzhou 13 manned spacecraft, and the Tianzhou 2 and Tianzhou 3 cargo spacecraft. The second flight mission was a complete success, and the mission objectives of the key technology verification stage were successfully completed, laying a solid foundation for the implementation of the mission during the construction phase of the space station.
