On April 16, the return module of Shenzhou 13 manned spacecraft successfully landed in the predetermined area of Dongfeng landing site.

First, a new way for astronauts to leave the capsule. Different from the past, every astronaut of Shenzhou 13 will be sent to the medical supervision and medical insurance carrier, so as to shorten the exposure time of the astronauts in the field environment after they leave the capsule as much as possible.

“When astronauts fly in orbit for a long time, their bodies will suffer bone loss, muscle atrophy, decreased immunity and other changes, which will bring great challenges to the medical supervision and medical support tasks after return.” Wu Bin, researcher of China Astronaut Research and training center and deputy chief designer of astronaut system, said.

Second, the medical supervision and medical insurance model is new. Bian Hancheng, researcher of Jiuquan Satellite Launch Center and deputy chief designer of manned space engineering landing site system, introduced that Dongfeng landing site has newly developed astronauts’ special seats, astronauts’ medical supervision and medical insurance vehicles and astronauts’ medical supervision and medical insurance tents, forming a new model of astronauts’ medical supervision and medical insurance guarantee with preferred medical supervision and medical insurance vehicles, alternative inflatable tents and guaranteed minimum use of medical supervision and medical insurance helicopters, Provide a more comfortable environment for the astronauts to spend the critical period of ground gravity re adaptation at the initial stage of landing, and lay a good foundation for the subsequent physical recovery of the astronauts.

The Shenzhou 13 search, rescue and recovery mission launched the second generation medical supervision and medical insurance vehicle for the first time. The facilities in the vehicle are fully equipped and equipped with temperature control system. Astronauts enter the vehicle by elevator and are no longer carried by search and rescue personnel.

The third is to respond to the new situation in the return season. This is the second time that Dongfeng landing site has carried out search, rescue and recovery mission, and it is also the first time that Chinese astronauts returned in spring. According to the characteristics of the windy and sandy climate in Ejina Banner in spring, the landing site system carried out search and rescue operations in advance to prepare rescue and protection measures for strong winds and dust environment.

Bian Hancheng introduced that in this mission, Dongfeng landing site has established a helicopter team, a fixed wing aircraft team and a ground team, with a total of three professional search and rescue forces, and established a sealing and control team at the periphery of the landing site, a mobile search and rescue team and a search and rescue reserve team to cooperate to complete the search and rescue mission. In addition, the flag and county governments around the landing area also organized dozens of militia units to provide support for professional search and rescue forces.
