So far, there have been two female astronauts who have carried out manned space missions in China, namely Liu Yang of Shenzhou 9 in 20 12 and Wang Yaping of Shenzhou 10 in 20 13. Liu Yang and Wang Yaping were both married before they were selected as astronauts. Perhaps because of this, some people will guess that female astronauts must get married to go into space.
However, this is not based on facts. The criteria for selecting female astronauts in China are very clear, and there is no requirement to be married. As long as their own quality is excellent, even unmarried women can be selected as astronauts to carry out space missions.
However, choosing married women as astronauts does have advantages. Married women tend to have more mature minds, which is very important for space flight.
Space missions are extremely risky, and astronauts need to bear enormous physical and psychological pressure, which is not something that ordinary people can do. If they are married women and have experienced natural childbirth, they are more resistant to stress and can complete space missions.
However, it should be emphasized that getting married and having children is not a necessary condition for female astronauts, but excellent physical and psychological quality is.
In addition, there is a common misunderstanding about female astronauts-female astronauts can't have children when they come back.
After returning to Earth, the female astronauts are still normal and can produce as usual. Neither Liu Yang, the first female astronaut in China, nor valentina tereshkova, the first female astronaut in human history, have given birth after returning to the earth, and their offspring are healthy, and there is no problem of infertility or drug prohibition.
However, space flight is accompanied by certain risks. In space, radiation is much stronger than on the ground, which will have a certain impact on the human body. In addition to radiation, long-term exposure to low gravity is not good for health.
Recent research shows that during the space flight, the astronauts' immune system will be out of balance, and the herpes virus that was previously dormant will be reactivated. Although these viruses will not affect astronauts themselves, when astronauts return to Earth, active viruses may pose a threat to susceptible people. Therefore, in order to ensure the health of astronauts, it is necessary to strengthen relevant research to ensure that the reactivated virus will not bring trouble to astronauts.
