The outgoing activity is one of the most important tasks of Shenzhou XII and has attracted everyone's attention. On July 4, three astronauts Nie Haisheng, Liu Boming and Tang Hongbo coordinated to successfully complete the first outgoing activity of the space station for about 7 hours.
The mission was complex, difficult to operate, and the activity time was long. So, after the end of the mission, what was the physical state of the astronauts at that time?
After the first out-of-the-cabin activity, the astronauts are in good condition
Astronaut Liu Boming: 02 report, 02 As the first space station out of the capsule astronauts, thank you to all the scientific researchers participating in the research and test, thank you for the strong support of the people of the whole country, I will continue to go out of the cabin, will fly higher, the space station will be built bigger, thank you.
On July 4, the three astronauts of Shenzhou XII worked closely together to successfully complete about 7 hours of outgoing activities, which was also the first outgoing activity of the Chinese space station. The task is complex, the operation is difficult, and the activity time is long, which undoubtedly tests the physical strength and energy of astronauts.
Li Yinghui, deputy chief designer of the astronaut system, researcher of the China Astronaut Scientific Research and Training Center: Everyone has seen that this outgoing activity has performed very well. The data back tells us that it's all OK, that these data are consistent with our expectations, and that their bodies are able to cope well.
The medical supervision and medical insurance personnel who are responsible for paying close attention to the physical health status of the astronauts on the ground also introduced the various indicators of the astronauts' bodies in detail for the reporter.
Xu Chong, director of the Medical Supervision and Medical Insurance Office of the Chinese Astronaut Scientific Research and Training Center: From the monitoring of cardiovascular function, including the recovery of fatigue, the recovery of the air pressure function of the entire ear, and the repair of the eardrum are also very good, there are no injuries and injuries due to the outflow of the capsule. The effect of the whole capsule is also very good, the astronaut's body, sleep including eating and drinking, body metabolism, nutrition, health status, after our comprehensive assessment is very good.
Xu Chong introduced that in order to ensure that astronauts can safely and smoothly spend three months of space life, the space and the earth must complete a medical inquiry call every day, conduct a health assessment once a week, and conduct a comprehensive assessment every month. After a month, the three astronauts can now be half doctors themselves.
Xu Chong, director of the Medical Supervision and Medical Insurance Office of the China Astronaut Research and Training Center: Astronauts are a good ultrasound doctor, and their ultrasound skills are also very good. They had to do cardiac ultrasounds and abdominal ultrasounds on each other, including ultrasounds of the muscles of the lower limbs, and perform ultrasound function imaging assessments, and routine medical examinations were a piece of cake for them.
The space station assembly is currently operating steadily
After the Shenzhou XII manned spacecraft and the Tianhe core module completed rendezvous and docking, a one-character configuration was formed. In orbit for a month, the space station complex has been operating steadily.
During the normal operation and management of the space station, each system adopts a distributed flight control work mode, and the astronaut support hall of the astronaut scientific research and training center has set up ten permanent posts such as Shuguang Post, The Overall Post, and the Crew Monitoring Post, as well as more than a dozen support posts. They adopt a work model that synchronizes with astronauts' space-to-earth work and rest to support astronauts' working life and health in orbit.
The new distributed operation and control work mode is that the Beijing Aerospace Flight Control Center implements the operation and control work of the space station through the distributed operation control system and the astronaut support center, the payload support center and the orbiting spacecraft support center.
Wang Saijin, deputy chief engineer of Beijing Aerospace Flight Control Center: The interconnection of heaven and earth is mainly through the consultation of special words, mission words and collaborative words, as well as two-way video of space and earth. We also communicate with astronauts through the mail system to ensure close coordination between space and earth. At present, the space station assembly is in normal condition, the posture is stable, the astronauts are in good physical and mental state, and the energy balance of the space station.
Since the astronauts were stationed for a month, their work and life have been smooth, and the various systems have coordinated with each other to complete tasks such as rendezvous and docking, propellant replenishment, and astronauts out of the cabin, and have verified key technologies such as large-scale assembly control, assembly and construction, and extravehicular maintenance in orbit.
30 days in orbit, a number of space experiments have been carried out
As of the 17th, the three astronauts had completed one-third of the mission. What did they accomplish in those 30 days?
From handling and sorting, to everything in place, to the orderly development of various experiments, astronauts have been full of daily work arrangements for a month, and at present, astronauts are carrying out a number of space experiments.
Li Yinghui, deputy chief designer of the astronaut system, researcher of the China Astronaut Scientific Research and Training Center: We have a series of experiments, including engineering and medical experiments, and some medical examinations, which are carried out to the content stage of smooth maintenance and completion of the work as planned.
The field of aerospace medicine is one of the main contents of space experiments, mainly to study and solve the medical problems and human factors engineering problems that restrict the long-term flight of manned spaceflight and affect people. In the Celestial and Core Cabin, we can see the cabinet behind the flag, which is the device used to conduct this research.
Using this cabinet, the first thing to do is the biorhythm experiment. In layman's terms, it is also the study of the biological clock of astronauts' space life. So does the space environment have an impact on biological rhythms? The cabinet will be presented through the data.
On the 14th, the watch that astronauts began to wear was an important terminal for collecting astronauts' biorhythm data.
Li Yinghui, deputy chief designer of the astronaut system, researcher of the China Astronaut Scientific Research and Training Center: Through the watch, we can accurately report the sleep time, sleep degree, vibration of sleep rhythm and phase changes, and we will also find changes between rhythms through heart rate and these records during his exercise, which is the data that must be obtained during long-term flight.
Li Yinghui introduced that in the space station stage, the field of aerospace medicine involved in the formation of a total of 49 space experiment projects, and Shen XII undertook 14 of them.
