The risks that the astronauts may encounter in space are: 1, sealing cabin or (when space walking), the Aerospace uniform is broken by space garbage, causing oxygen leakage. 2, the space cabin fails, which makes the astronauts unable to maintain their lives and cannot wait for the rescue. 3. During the return process, the carrier rocket or spacecraft fails, resulting in the launch or return failure (spacecraft disintegrate, explosion, parachutes are not opened, and no major deviations will be returned to the predetermined orbit.) 4, do not rule out no exclusion Attack by the high -level life body of the universe. 5, may encounter cosmic radiation. The biggest threat in this area comes from the outbreak of the sun. This is a fierce outbreak of the solar atmosphere, which will instantly release electromagnetic radiation. It can release huge energy of 1020 to 1025 in a few minutes to ten minutes, which is equivalent to tens of billions of giant hydrogen bombs exploded at the same time. Sugging of health: The weight loss is the biggest test encountered by astronauts. He Xinxing, director of the Aerospace Environmental Medicine Research Office of the China Aerospace Council Research and Training Center, said that in the heavy environment of the space track, blood transferred to the head and upper limbs, and the regulation of human body fluids would change. Then there may be problems with cardiovascular. In space, the astronauts walked on their feet, but floated with their arms. This can cause muscle atrophy and osteoporosis. During the flight, the ground support team will comprehensively use medical inquiries, basic physiological indicators, routine urine testing and other means to regularly implement health status assessment; pay attention to strengthening microbial control in the cabin, and configure preventive treatment drugs and related related medical instruments. In addition, this task has established a long -range medical support system for the first time. Through the consultation of heaven and earth collaboration, the problem of "seeing a doctor" on the track of astronauts. At the same time, it has created a "space gym" for astronauts, equipped with protective equipment and exercise equipment to reduce the adverse effects of weightlessness as much as possible. For example, the use of bands, unwell reactions such as head swelling and nasal congestion in the early stage of protecting flight; comprehensive protection of cardiopulmonary function decline, muscle atrophy, and bone loss by using tensilers and bicycle skills to exercise and wear penguin clothes. The so -called "penguin clothing" is actually a exercise tool. In the state of weight loss, human muscles will lose gravity stimulation and shrink. Putting on the "Penguin suit" can give people a confrontation force, maintain continuous stimulation of muscle strength, and prevent weight loss and loss of bone. The tensilers increase the exercise of the lower limbs and back muscles. Astronaut System experts say that generally speaking, astronauts spend an hour in space for exercise every day. The ground support team will also observe and evaluate the psychological state of the two astronauts during the flight and provide psychological support. Especially in the middle and late stages, the emotions, fatigue, human -machine interaction, world interaction, and interaction between the two will focus on observation and records. Huang Weifen said that in this flight mission, the ground team provided a psychological soothing system based on virtual reality technology. Through this system, astronauts can see family, family scenes, and familiar environments. Improved the heaven and earth information exchange system, astronauts can communicate information with the ground at any time, convey emails, and conduct audio and video communication with friends and relatives. Ter aerospace officers themselves also brought with interesting songs, videos, etc., including photos of family members. After a day of busy day, you can take it out or watch in about 1 hour of leisure time at night. This is also a psychological relaxation.
