The Shenzhou 13 astronaut crew has been working and living in orbit for 5 and a half months. At present, the three astronauts are nervously making preparations before returning, and the Shenzhou XIII spacecraft will embark on its return journey as planned.
At present, the space station's core module complex is operating stably in orbit, and the astronaut crew is scheduled to return to the ground in mid-April. The main job of astronauts in these days is to sort out the cargo bags, strengthen physical exercise, and prepare for return.
Zhai Zhihong, deputy director of the Aerospace Medical Engineering General Office of the Astronaut Center: The key work before the return of the Shenzhou 13 crew should 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, complete the sorting and packing of downlink items, in addition, it is necessary to set the unmanned flight mode state before returning and the work status inspection of the spacecraft, 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 boarded the Shenzhou 13 manned spacecraft at the Jiuquan Satellite Launch Center to enter the Tianhe core module, becoming the second batch of astronauts to stay on the Chinese space station. In the Shenzhou 13 manned mission, three astronauts, with the support of ground scientific and technological personnel, successfully completed 2 capsule departure activities and 2 "Tiangong Classroom" space teaching activities, carried out a number of scientific and technological experiments and application projects, and Wang Yaping became the first female astronaut in China to carry out spacecraft activities. For the first time, the astronauts completed the docking of the cargo spacecraft with the space station through hand-controlled remote operation in orbit, and the flight crew set a new record for the continuous flight time of Chinese astronauts in orbit, laying a solid foundation for the subsequent construction of the space station.
The Dongfeng landing field is ready to ensure the safe return of astronauts
It is understood that the Dongfeng landing site of the Jiuquan Satellite Launch Center is ready to ensure the safe return of astronauts.
At present, all search and rescue forces in the Dongfeng landing field of jiuquan satellite launch center have all entered the field, and the major systems have carried out sub-system training, organized inter-system matching exercises, and will plan to carry out a number of system-wide comprehensive drills in the follow-up. In view of the new mode of Shenzhou 13 return, the Search and Rescue And Recovery Brigade of Dongfeng Landing Site has taken various measures to ensure the safe return of astronauts.
Bian Hancheng, deputy chief designer of the landing field system of the manned space project: The Shenzhou 13 mission, the astronauts are in orbit for 6 months, belongs to the long-term on-orbit residence, we have made some new explorations on the basis of the Shenzhou 12 mission, in the ground medical supervision and medical insurance protection. Through comprehensive exercises, we will further improve the plans and plans and improve our ability to accomplish tasks.
