The Shenzhou 13 astronaut crew has been working and living in orbit for five and a half months.
At present, the three astronauts are intensively preparing for their return, and the Shenzhou 13 spacecraft will embark on its return journey as planned.
At present, the core module assembly of the space station is running stably in orbit, and the astronaut crew plans to return to the ground in mid-April.
The main task of astronauts these days is to organize the cargo bags, strengthen physical exercise, and prepare for the return.
Zhai Zhihong, deputy director of the General Office of Aerospace Medicine Engineering of the Astronaut Center: The key work before the return of the Shenzhou 13 crew is to complete the inventory of this item and the transfer of materials, complete the comprehensive cleaning and maintenance of the cabin environment, control the growth of microorganisms, and complete the downlink. In addition, the unmanned flight mode status setting and the working status of the spacecraft must be checked before the return, and the astronauts should strengthen the weightlessness protection exercise and make various preparations before returning.
On October 16, 2021, astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu took the Shenzhou 13 manned spacecraft into the Tianhe core module at the Jiuquan Satellite Launch Center, becoming the second batch of astronauts to stay in the Chinese space station.
During the manned flight mission of Shenzhou 13, three astronauts, with the support of ground scientific and technical personnel, successfully completed two out-of-vehicle activities, two "Tiangong Classroom" space teaching activities, and carried out a number of scientific and technological experiments and application projects. , Wang Yaping became China's first female astronaut to carry out extravehicular activities.
For the first time in orbit, the astronauts completed the docking of the cargo spacecraft with the space station through manual remote control. The flight crew set a new record for the continuous in-orbit flight time of Chinese astronauts, laying a solid foundation for the subsequent construction of the space station.
Dongfeng landing site is ready to ensure the safe return of astronauts
It is understood that the Dongfeng Landing Site of Jiuquan Satellite Launch Center is ready to ensure the safe return of the astronauts.
At present, all search and rescue forces at the Dongfeng Landing Site of Jiuquan Satellite Launch Center have entered the site. The major systems have conducted sub-system training and organized inter-system matching exercises. In the future, multiple system-wide comprehensive exercises will be planned.
In response to the return of Shenzhou 13 to a new mode, the Dongfeng Landing Site Search and Rescue Brigade took various measures to ensure the safe return of the astronauts.
Bian Hancheng, deputy chief designer of the landing site system of the manned space project: On the Shenzhou 13 mission, the astronauts are in orbit for 6 months, which is a long-term in-orbit stay. On the basis of the Shenzhou 12 mission, we are in the ground medical supervision and medical insurance In terms of security, some new explorations have been made.
Through comprehensive drills, the plans and plans will be further improved, and the ability to complete tasks will be improved.
