Shenzhou 14 returns to the earth.
, the only female astronaut, Liu Yang, who performed the space station resident mission, although there was a certain degree of swelling on her face, from the overall mental outlook, Liu Yang's physical condition is still relatively good.
Liu Yang's face swelling
. With the return of the female astronaut Liu Yang, there was also a rumor circulating on the Internet that the female astronaut was prohibited from giving birth after returning to Earth.
Objectively speaking, astronauts performing missions in space must fight against various radiation in the universe at all times.
Cosmic ray
You should know that once a person is exposed to radiation, it will inevitably affect his health, and in severe cases it will even affect gene fragments. In this way, the impact of radiation will further affect the next generation.
is also why the rumors that female astronauts return to Earth to ban childbirth are still somewhat reasonable.
But will this be true? How terrible are cosmic rays in
?
Here, it is necessary for Dachuan to take you to understand how much cosmic ray threatens astronauts.
Astronaut
From a physical definition, cosmic rays are actually from outer space, charged high-energy -second atomic particle .
includes the well-known α, β rays , and γ rays , which can be found in cosmic rays.
Cosmic ray
Take γ ray as an example. rays have extremely strong radioactive .
Although gamma rays are often used as radiation surgery or other radiation science experiments in life.
But if ordinary people are accidentally irradiated by gamma rays, even in just a few seconds, they are very likely to suffer from severe radiation diseases or even die.
γ-ray flaw detector
There are many high-energy particles that are stronger than gamma rays. Therefore, it is absolutely dangerous for us humans to be exposed to the cosmic radiation environment, and astronauts are no exception.
But it is worth mentioning that the space suits on the astronauts, the spacecrafts on which the astronauts board, and the space stations where the astronauts settle in are all radiation-proof.
Cosmic rays cannot harm astronauts
In this way, the astronauts can be fundamentally guaranteed not to be harmed by cosmic rays.
Female astronaut returns to Earth to prohibit childbirth?
See this, I believe everyone should have figured it out.
Although cosmic rays pose great threat to astronauts, they are protected by space suits, spacecrafts, and space stations. Astronauts will not be harmed by cosmic ray radiation.
Internal to the Tiangong Space Station of China
Therefore, the statement that the female astronaut returns to the earth to prohibit childbirth cannot be caused by cosmic rays.
Speaking of which, for female astronauts performing missions in space, the biggest threat lies in the microgravity environment of the universe .
The microgravity environment of the universe
We all know that the physiological structure of women is different from that of men. Due to the physiological structure, when women grow to a certain age, they will start to have menstruation , and it will appear once a month.
On earth, women's menstrual periods are already very uncomfortable. In addition to physical pain, they also have to endure psychological pain due to the "fluctuations" of the body's internal endocrine.
dysmenorrhea
In the microgravity environment in space, there is no gravity on the earth. has no constraints on gravity, and the blood in the astronauts will lose gravity.
The most obvious manifestation is that after astronauts live in the space station for a period of time, their faces will become congested and swollen. This is the manifestation of blood evenly distributed in the astronauts with the erection of their hearts without gravity.
Wang Yaping's face swelling in space is very obvious
If a female astronaut experiences menstruation in space, in this environment where gravity is lost, blood will be difficult to excrete. It can only be done by sucking with tools to expel blood from the body.
I have to say that this is a very painful thing.
Female astronaut Wang Yaping
In order to solve this problem, the female astronaut had to temporarily stop menstruation by taking medicine, , until the space station mission is over and return to Earth, then condition the body to restore normal menstruation.
Although doing so can avoid menstruation in the space station, it will undoubtedly cause unimaginable damage to the physical health of the female astronaut.
It is precisely because of this that the microgravity environment of the universe has become the biggest threat that female astronauts need to face.
Female astronaut Liu Yang
But then again, even if the microgravity environment of the universe seriously threatens the health of female astronauts, such a threat will not have any impact on the reproduction of female astronauts.
As long as you return to Earth and recondition your body, you can still have children...
Space life will not affect astronaut fertility
Generally speaking, is traveling in space. From a scientific point of view, there are no factors that will cause female astronauts to be unable to have children.
Liu Yang breaks the rumor with his actions
In fact, the statement that a female astronaut returns to the earth to prohibit childbirth is the rumor woven by some people . As more people spread
, more people will choose to believe such rumors.
Rumor
Ko Dachuan wants to tell you that years ago, female astronaut Liu Yang broke this rumor with practical actions.
As early as 2012, Liu Yang completed a space mission and successfully returned to Earth.
Liu Yang entered space without giving birth
. In 2015, the third year after Liu Yang returned to Earth, Liu Yang participated in a speech on "Love in the Good Family of National Defense".
In the speech, Liu Yang said that he had upgraded to a mother and proudly showed everyone the child's clothes.
Liu Yang shows her children's clothes
This speech made more people re-recognize Liu Yang. She is no longer just a space hero, but has transformed into a great mother...
Of course, this speech of is also considered to be an action, breaking the rumors that female astronauts are prohibited from giving birth after returning to Earth.
How much sacrifice are the astronauts making for the aerospace industry?
It is false to prohibit fertility after returning to Earth, but the sacrifices made by the astronauts in their space missions are true.
Chinese astronaut
As Okawa mentioned earlier, female astronauts chose to take drugs to suppress menstruation in order to avoid experiencing menstruation in space. There are actually many similar sacrifices, and there are many sacrifices for male and female astronauts.
Astronauts sacrifice the greatest sacrifice, in addition to health, there is also life.
Astronauts who participated in the training
Astronauts are different from other professions. We only see the side of them entering space and bringing glory to the country, but we cannot see the side of them behind this, training hard and long-term separation from their families.
Just like Liu Yang's farewell in his circle of friends before he set out to the space station on June 5:
"Every June 1st, I write a letter to you as a gift for growth. I am sorry that I can't be by your side this year. I can only write this letter with the bright moonlight by the beautiful river of water! The pen is silent, the paper is short and the love is long, and I give me a deep blessing. I wish you and all the children in the world will have love, warmth and light in their lives, and the innocence will last forever, and the flowers are as bright as flowers."
In just a few short sentences, they can truly express Liu Yang's love and longing for his two children.
Liu Yang’s circle of friends
The biggest pain in life is probably separation from your dear.
Even if it takes a few minutes, it is enough to make people cry...
The female astronaut held back her tears, which is heartbreaking
When she should have watched the children grow up, she had to leave them, and she didn't know whether this trip was a blessing or a disaster.
Speaking of which, this is probably the biggest sacrifice that astronauts have to make.
