On the afternoon of December 7, the China Astronaut Scientific Research and Training Center held a meeting with reporters of the Shenzhou 12 astronaut crew in Beijing Space City. This is the first time that the Shenzhou 12 astronauts have officially met with the media and the public after returning in the group. At the meeting, Jing Haipeng, captain of the astronaut brigade, introduced the recovery situation and follow-up plans of the passengers after their return.
As China's first crew stationed on the space station, the three astronauts of Shenzhou XII have received great attention from people, as long as it is a public video data, many people watch it. Shenzhou 12, as China's first crew stationed in space, took off on the Long March 2 F rocket on June 17, docked 6 hours later, entered the space station for 8 hours, and returned to Earth on September 17 after a three-month intense mission. The 3-month on-orbit residency is already the longest-term on-orbit multiplication in China.
On September 17, the process of returning and recovering the manned spacecraft was broadcast live, and I believe many people watched the live broadcast. There are several points in the live broadcast, first of all, the astronauts in the cabin to assist the staff outside the cabin to open the hatch, indicating that they still have a certain ability to move inside, and then with the assistance of the ground medical supervision and medical personnel to get out of the cabin, although not completely autonomous, but still have a certain ability to move, and then sit on the characteristic human efficacy seat, waiting for the ground personnel to transfer them.
That evening, the three astronauts had already been transferred to Beijing, where they were not heard from until November 8 after a brief greeting ceremony at the airport. Then, on the day of Reporters' Day on November 8, the three astronauts gave exclusive media interviews to the astronaut brigade, revealing their physical condition, and there was no news of them after that. Finally, after another month (30 days), today the three astronauts finally made a public appearance for media interviews.
According to reports, the recovery period after the normal return of the group flight is mainly divided into three stages: isolation recovery stage, convalescence recovery stage and recovery observation stage. At present, from the state of the three people at the press conference, the astronauts' mood is very stable, the psychological state is also very good, and when they walk into the venue and walk on the podium, they walk fast, reflecting that the muscle strength and endurance have been restored to a certain extent, basically not affecting the daily walking and sitting, and the recovery is quite good.
Of these three stages, the first two stages are more cautious, and the first stage is the isolation recovery period, which as the name suggests is isolation. The isolation in manned spaceflight is level III isolation, because the microorganisms on the astronauts may mutate, although the possibility of returning to the earth to cause the spread of pathogens is very small, but the change of the microflora also leads to the impact of human immunity, and the immune system itself is also affected, in order to protect astronauts also need to isolate to avoid the outside world of people bringing pathogens to cause astronaut infections. This stage also requires a lot of medical examinations.
Then it moves on to the second stage, which is mainly based on medical examination analysis, customized personalized recipes, nutritional supplementation for each person's different physical characteristics, about 30 days. At this time, you can also carry out some rehabilitation training similar to long-term bed rest, which can initially restore the strength of the muscles, so that astronauts can sit and walk more freely, without having to rely on others to walk, so that the mood of astronauts is also better, and it is always uncomfortable to be carried by others.
That's why they were largely unheard of for the first two months after they returned to Earth, not because they didn't let us see the astronauts at all, but because they needed a quiet, less disturbing environment to resume training. After returning from the mission, the three astronauts will be transferred to normal training work. That is to say, the three of them may also participate in China's manned missions as astronauts in the future and continue to contribute energy to the construction of China's space station.
On September 17, when they returned to Earth, many of the partners who watched the live broadcast found a phenomenon, that is, the faces of the 3 of them suddenly looked like a lot of wrinkles, which was related to the puffiness of the faces in space. In space, the blood is redistributed, and the increase in blood in the chest cavity, brain, etc. causes facial puffiness, and the Shenzhou 13 multiplier also has the effect of this problem, and after returning to The Earth, due to the action of gravity, the body fluids are rapidly redistributed, so the skin quickly becomes deflated.
This stage is the most dangerous, because it has adapted to the blood filling state in the head, chest and other places, and suddenly the blood flows downwards, which will lead to a decrease in cardiovascular and cerebrovascular perfusion, so it is also forbidden to move around at this time, which is why you must sit on a chair after March to be carried away. The re-adaptation of gravity is the most dangerous in the initial stages.
