At 18:48 on the same day, three astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, successively entered the Tianhe core module of the space station. As of July 17, three astronauts have been in orbit for a "full moon". What's the status of the three astronauts after a month's space "business trip" On July 4, the three astronauts of Shenzhou 12 cooperated closely and successfully completed about seven hours of extravehicular activities, which was also the first extravehicular activity of the Chinese space station. The complex task, difficult operation and long activity time are undoubtedly a great test for the physical strength and energy of astronauts < p > Li Yinghui, researcher of China astronaut scientific research and training center and deputy chief designer of astronaut system, said: we can see that this extravehicular activity performed very well. The data back tells us that all this is OK. These data are consistent with our expectations, and their bodies can cope well < p > the medical supervision and medical insurance personnel who are responsible for paying close attention to the health status of astronauts on the ground also introduced the indicators of astronauts' health in detail Xu Chong, director of medical supervision and medical insurance Department of China astronaut scientific research and training center, introduced: from the monitoring of cardiovascular function, including the recovery of fatigue, the recovery of the whole ear pressure function, and the repair of tympanic membrane, there were no injuries or injuries due to the extravehicular. The effect of the whole extravehicular is also very good. The astronaut's body and sleep, including eating, drinking, metabolism, nutrition and health, are very good after our comprehensive evaluation < p > he said that in order to ensure the astronauts to spend three months of space life safely and smoothly, they need to complete a medical inquiry call every day, conduct a health assessment every week, and conduct a comprehensive assessment every month. After a month, now three astronauts can be half doctors themselves < p > "astronauts are very good ultrasound doctors, and their ultrasound skills are also very good. They have to do heart ultrasound, abdominal ultrasound, including lower extremity muscle ultrasound, and evaluate the ultrasound function. Routine medical examination is a piece of cake for them. " < p > space medical experiment < / P > < p > the field of space medicine is one of the main contents of space experiment, which mainly studies and solves the medical problems and human factors engineering problems that restrict the long-term flight of manned space. In Tianhe core cabin, you can see the cabinet behind the national flag, which is the device used for this research < p > using this cabinet, the first step is the biological rhythm experiment. Generally speaking, it is the biological clock that studies astronauts' space life. So will space environment affect biological rhythm? The cabinet will be displayed through data < p > on the 14th, the wrist watch that astronauts began to wear is an important terminal to collect the biological rhythm data of astronauts < p > Li Yinghui, researcher of China astronaut scientific research and training center and deputy chief designer of astronaut system, introduced: through the wrist watch, we can accurately report the sleep time, sleep degree, the oscillation of sleep rhythm and the change of phase. At the same time, we can also find the change between rhythms by recording heart rate and his movement process, This is the data that must be acquired in long-term flight < p > in the stage of space station, 49 space experiment projects have been formed in the field of space medicine, and Shenzhou 12 is responsible for 14 of them < p > the 30th day of on orbit work: routine medical examination, watching "news broadcast" and exercise < / P > < p > July 16 is the 30th day of three astronauts' on orbit work. Their work on that day is to carry out routine medical examination, and one of the important tasks is the removal of carbon dioxide and the removal of micro harmful gas subsystem fasteners < p > when CCTV reporters came to the astronaut center, it was more than 4 p.m., Nie Haisheng and Tang Hongbo were replacing the CO2 removal device of the environmental control and life support system. On that day, the work of the three astronauts started at 8 a.m. and finished the platform inspection of the manned spacecraft and the collection of trace elements in the air within 4 hours in the morning; Afternoon work starts at two o'clock; At about six o'clock in the evening, the three astronauts had dinner on time < p > at more than 7:00 p.m. on the 16th, the three astronauts were concentrating on watching the news program. After they entered the Tianhe core module, the ground would send them news programs regularly, which was also one of the most important means for them to obtain ground information < p > after watching nearly an hour's TV program, the three astronauts officially started the sport mode. Liu Boming was riding a space bike, Tang Hongbo was exercising on the space platform, and commander Nie Haisheng was talking to the ground, discussing the work plan of one day and the work plan of the next day. The amount of exercise of these three astronauts should be determined according to the physical condition of each of them < p > Li Yinghui, deputy chief designer of China astronaut scientific research and training center and astronaut system, introduced that their current exercise is a home-made meal, which is available every day, and everyone has their own "prescription". The intensity should be said to reach 60% to 80% of everyone's maximum ability, and the intensity belongs to the upper middle. The longer the flight time, the greater the intensity. Only in this way can they maintain their physiological effects against weightlessness After the rendezvous and docking between the shenzhou-12 manned spacecraft and the Tianhe core module, a zigzag configuration has been formed. Since one month of on orbit flight, the space station assembly has been operating stably < p > during the normal operation and management of the space station, each system adopts a distributed flight control mode, and the astronaut support Hall of the astronaut research and training center has set up ten permanent posts, including dawn post, general post, crew monitoring post, and more than a dozen support posts. They adopt the work and rest mode of keeping pace with the astronauts to support their on orbit work, life and health < p > the new distributed operation control mode is that Beijing aerospace flight control center cooperates with the astronaut support center, payload support center and on orbit spacecraft support center to implement the operation control of the space station through the distributed operation control system < p > Wang SAIJIN, deputy chief engineer of Beijing space flight control center, introduced that the space-time interconnection is mainly carried out through the space-time special telephone, task telephone, collaboration telephone and two-way video.
