Space is very romantic for many people, where the stars shine and fill people with infinite fantasies. However, space is lonely and dangerous. The environment of space and our earth have a world of difference, there is no gravity in space, people will be in a state of weightlessness for a long time; there is strong radiation in space, it is easy to cause harm to the human body, it is said that in space, astronauts are exposed to 20 times the amount of radiation on the earth, which is a huge test for astronauts.
Long-term weightlessness, not all people can accept, in the weightless state, the human body's bone density will change, the normal physiological activities of the human body will also be affected to varying degrees.
That's why every celestial astronaut needs to be carefully selected, and they are subjected to both physical and psychological extreme challenges.
In people's cognition, it seems that the number of male astronauts is more numerous, and China also has the participation of women for the first time when the second batch of astronauts is selected.
<h1 class="pgc-h-arrow-right" data-track="5" > the advantages of female astronauts</h1>
The Chinese female astronauts that everyone is very familiar with are Liu Yang and Wang Yaping, who passed five levels and slashed six generals along the way, and finally stood out among many candidates and became the heroines that Chinese were proud of. Liu Yang performed the Shenzhou 9 mission, and Wang Yaping carried out the Shenzhou 10 mission.
Many people can't help but wonder, in the process of carrying out space missions, are women more advantageous or inferior?
The space mission is not as romantic as we think, it is a high load and difficult activity. In the earliest days, it was believed that women's bodies were weaker than men's, and their physical strength could not keep up, and it was difficult to withstand the harsh environment in space, let alone carry out tasks, so for a long time in human manned spaceflight, women were excluded.
Then, a recent research survey suggested that female astronauts were better suited to work on the space station than men.
The study found that female astronauts are more suitable for long-term survival in microgravity environments, which is determined by women's innate preponderance. For example, women can tolerate long-term loneliness more than men, and such a psychological environment is more suitable for space travel.
<h1 class="pgc-h-arrow-right" data-track="11" > gender differences in space work</h1>
It has to be admitted that women's strength is generally inferior to that of men, so it is difficult to match male astronauts in some operational activities. And because of some physiological factors, female astronauts will have some other special needs in life.
Therefore, there is a basis for the imbalance in the proportion of male and female astronauts in the aerospace industry, which is not simply "gender inequality", but greatly improves the completion rate of tasks according to the different characteristics of men and women.
Therefore, in space missions, tasks such as emergency capsule exit and spacewalk are generally taken away by men. But women are also more sensitive and agile due to the metabolism of estrogen and magnesium, and are more suitable for living in this closed and lonely environment for a long time.
For women, there are always a few days in a month, so how to solve the physiological period of female astronauts?
<h1 class="pgc-h-arrow-right" data-track="16" How do female astronauts solve menstrual problems >? </h1>
First of all, many people have misunderstood that astronauts who have experienced space radiation may be infertile, but in fact, the results show that space radiation does not lead to female infertility, and many female astronauts at home and abroad can prove it with facts.
So how to solve the menstrual period? Do women's menstruation go backwards due to weightlessness? Everyone knows that menstrual blood is to be discharged, and if it is retrograde, it may be poured back into the pelvic cavity. According to the current results of the study, the microgravity environment in the capsule does not have any special effect on the menstrual period of women, which is basically the same as they are on Earth.
And so far so many female astronauts have never raised the corresponding problem. On shorter missions, female astronauts may change their menstrual cycles by taking birth control pills to ensure the smooth execution of the mission.
However, due to some differences in physiological conditions, female astronauts do get a little preferential treatment in space life, but they are worth it.
Hats off to every great astronaut.
