Why do astronauts pull out all their fingernails before they fly into space?

People who like to watch space documentaries may know that the living environment in space is completely different from the earth, one is that there is no air, and the other is that there is no gravity, and it is particularly inconvenient for astronauts to do many things in the spacecraft, such as washing hair, eating, and going to the toilet.

Because space has no gravity, many things are not as convenient as on Earth.

But you may not know that when astronauts go to space, even their nails have to be pulled out! Those who have seen Huanzhu Gege may know that ten fingers connected to the heart and nail pulling was a kind of torture in ancient times, and it is hard to imagine how those astronauts endured this pain before they could do it.

So why do astronauts do this? It turns out that in space, it is inconvenient to do anything, especially to cut nails, and nails will grow crazy in space, once they do not decrease for a period of time, then the nails will be compressed, and pieces of the whole will fall off! If you are injured in space because your nails fall off, blood gushes out, and it is very difficult to stop the bleeding, and you may lose your life.

Therefore, former astronauts had to pull out all their fingernails and heal before they could go to space.

So you can imagine how hard it is to be an astronaut, right? Not only that, but from the time of candidacy to the confirmation of becoming a real astronaut, astronauts have to go through countless tests and exercises to make their bodies able to cope with various mutations in space! And among them, there are countless people who have been cut down, and what is left is the business in the elite!

However, it is worth mentioning that with the development of technology, today's astronauts do not have to endure the painful process of pulling their nails as before, as long as they cut their nails a little shorter, they can fly into space. But what makes it good is that astronauts can't have scars on their bodies, can't they? So if the nail is pulled out of the scar, is it still counted?

Why do astronauts have to pull out all their fingernails before going to space? After reading it, a cold sweat broke out.

The consequence is that you can't breathe, and then you dieWe all know that there is no air in space, and there is air in the spacesuit, so we can move in space, and if we take off the spacesuit, then we are in an environment where we can't breathe.

Then the astronaut will die immediately, because there is no oxygen in space, and the temperature is very low, which will directly affect the life of the astronaut.

He will definitely be affected by the environment of this vacuum, lose the ability to breathe, and will most likely be frozen, because it must be cold in that place.

Astronauts fly into space to investigate the effects of weightlessness on the human body, conduct microgravity experiments, and conduct life science and biotechnology experiments. Examining the effects of weightlessness on the human body This study will help to understand the impact of the space environment on the human body, and to develop and use space resources for mankind to achieve longer space travel.

What do astronauts do when they fly into space.

Since the realization of manned spaceflight, astronauts have studied the physical laws of material processing under microgravity conditions in space, produced many new materials, and at the same time, the research on space material processing technology has also achieved rapid development.

A series of biological experiments conducted by astronauts in space are mainly biosphere studies on the study of biological substances, energy cycles and regulation.

Gravimetric biology studies of the use of microgravity to facilitate life processes and how the microgravity environment affects the formation, function and behavior of organisms on Earth.

In space, nails grow very fast, and if they are not trimmed for a while, the nails will be compressed and the whole thing will fall off. And once you get injured in space, it is very dangerous, because the work of stopping the bleeding alone is very dangerous. So astronauts have to pull out their fingernails and heal before they can go to space.

The living environment in space is very different from that on Earth, the main thing is that there is no air and gravity, so it is very inconvenient for astronauts to do many things in spacecraft. However, with the development of modern technology, astronauts do not need to endure such hard work to pull out their nails, as long as they trim their nails shorter. Spine stool auspicious.

This is not cruelty, but to better protect the lives of astronauts.

Nails are an important part of the human body, in life can help us protect our fingers, but also convenient for life, without nails, our fingers will become very fragile, but if you go into space, nails can be said to be harmful and not beneficial. Some astronauts remove their fingernails before going into space, a process that is performed by professionals and does not harm the nail bed and nail matrix.

1. What kind of hardships do you need to go through to become an astronaut?

Many astronauts must be fully exercised before entering space, not only requiring physical fitness, but also psychological quality, with excellent scientific or technical skills, able to endure narrow space and freeze-dried food, and in the process of training, the nails must also be treated, because the nails are in a weightless state in space, once stuck in the glove, it is like a nail that constantly stings**, seriously hindering the astronaut's activities.

2. What do astronauts need to go through before going into space?

Everyone who wants to fly out of the atmosphere must go through the initial physical training, and in the process of training, they must strictly hone their survival skills. Most astronauts are required to be qualified to dive and pass a strenuous swimming test within a month, and astronauts are also aware of the potential dangers of space, which is known to have more radiation in space. In addition to theoretical learning, astronauts mainly train on four equipment: the out-of-cabin procedure training simulator, the simulated weightlessness training tank, the extravehicular suit test cabin, and the virtual reality trainer.

From the elaboration of the above problems, we can also see that there is great inconvenience for astronauts to live in space, and the rapid development of China's aerospace technology is inseparable from their efforts.

Because nails fall off directly in a vacuum environment, causing astronauts to feel severe pain, it is very difficult to treat wounds in space, so astronauts must remove all nails before entering space to prevent problems.

Theoretically, "armor pulling" is a psychological and physical test for astronauts. An excellent astronaut must not only have a high level of aerospace technology, but also have good psychological and physical qualities. A special spacesuit must also be worn after entering space; In addition, astronauts are required to wear personal protective equipment such as helmets, goggles, and nail clippers to prevent accidental injuries.

In a sense, it's a highly technical job.

Why do astronauts pull out their nails before going to space?

This is to prevent nail damage in the weightless environment of space, as this will allow the astronaut to do his job better. With the development of science and technology, in order to meet the needs of various spacecraft, the United States, Russia and other space powers have begun to treat the nails of astronauts before entering space.

What else do astronauts have to prepare for liftoff?

During the examination, the astronauts are required to wear a special type of glasses, which is to prevent water from entering the eyes. In addition, it is necessary to check the astronaut's breathing and pulse and other physiological conditions, and perform an electrocardiogram to ensure that there is no physical problem. Finally, some simple physical care should be done, such as some simple cleaning of the astronaut's eyes and ears.

After all this is done, the astronauts can be prepared for training.

Astronauts have to undergo very rigorous training before liftoff, which is unbearable and unimaginable for ordinary people. After entering space, because outer space is a vacuum state, if the nails cannot be processed in advance, there will also be a phenomenon that is easy to fall off automatically, in space, if the nails fall off, once they fall into an important equipment gap, it will also lead to the life of astronauts being threatened.

Because of the precision of the instruments in the capsule, astronauts are allowed to "pull out all their nails" before going into space to prevent nail clippings from entering the instruments and causing damage.

This is to protect the lives of astronauts, because if you don't pull out your nails, they can easily fall off automatically in space.

In rumors, the universe is considered to be a vacuum zone, although astronauts wearing spacesuits can isolate the cosmic environment and relieve weightlessness. But for nails, it can still be affected by space。Therefore, there is a saying that in space, nails can fall out because of the vacuum environment, which is a very painful thing.

In space, it's hard to treat wounds, and if they become infected again, it really can't return to the sky. Even if the wound heals, during the astronaut's return to Earth, the wound will crack open again due to pressure, causing secondary damage to the astronaut. So the astronauts will pull out all their nails before God.

In fact, it's just a rumor, not true. We all know that nails actually grow very fast. Even if all the nails were pulled out before God, many astronauts would work in space for a long time, such as China's recent Shenzhou 12, where astronauts had to work on the space station for three months.

If you pull out your nails, three months is enough for your nails to grow back a lot. Nail pulling in space is basically hard to do. Even if it does, it will bleed and cause the wound.

As long as you think about this rumor a little, you can know that it is a rumor. Before going into space, astronauts need to be fully armed, wrap themselves tightly and wear a special space suit.

If they don't pull out their nails ahead of time, their entire nails will automatically loosen and fall off due to the pressure of space when they fly into space. Otherwise, when you land in space, all your activities will be restricted, which is very different from Earth. If the fragments under the fingernails are cut inside the capsule, once they are not fully collected, there is a risk of fluttering around in the capsule.

Space capsules are some high-precision instruments.

If fragments of the nail flow into these instruments, they can cause damage to these instruments. Fragmented nails may also float in the capsule's eyes or ears, causing some adverse reactions。The living environment in space is very different from that of Earth.

The main thing is that there is no air and gravity, so it is very inconvenient for astronauts to do a lot on a spaceship. However, with the development of modern technology, astronauts do not need to endure the hard work of pulling out their nails, as long as the nails are trimmed shorter.

There are many interesting sayings about the life of astronauts compared to the earth, and there are many interesting sayings about the life of astronauts, among which there is a saying that astronauts need to pull out their nails before going to space, because in the vacuum environment of space, nails will fall off directly and be accompanied by pain, and there will be wounds, and it is very difficult to treat wounds in space, so it is necessary to pull out nails in advance to avoid wounds and infections.

This is really an outright rumor. Being able to make up this kind of rumor can be said to be really rich in imagination but slightly lacking in knowledge. Because astronauts are mainly active in spacecraft, even if they need to go out of the capsule, the spacesuit also has gloves, how can it directly expose the fingers to the vacuum?

Besides, pulling out the nails itself will cause wounds, and the heavens have been on a mission for a long time, and the nails will grow back, so do you have to deal with them again?

This rumor may have originated from a 2010 study that found that due to the design of some spacesuit gloves, some astronauts with larger hands are more likely to be injured by squeezing their fingers and nails, which may lead to nail loss in severe cases. But with improvements in the design of spacesuit gloves, these kinds of problems have disappeared.

In addition, if you pay attention to the astronauts in the Tiangong classroom, or take a closer look at the pictures of the astronauts exiting the capsule after successful landing, you will find that their nails are obviously fine, but they are very neatly trimmed and smooth - yes,Of course, you can cut your nails in the space station, just put the cut nails away so as not to float around.

For astronauts to go to space to pull out their nails. It's really ridiculous, completely unrealisticAnd this is a rumor-mongering behavior, astronauts go to space, there is no need to pull out their nails at all, if they pull out their nails, then it will be difficult for him to complete his future work tasks, plus astronauts need to go to space is a forced physique and a healthy body, if you pull out your nails, then it is not a healthy and physical body at all, for this matter is simply the existence of rumors.

The fact that astronauts need to pull out their nails before going to space is a rumor and is not in line with realityAnd there is such a statement is really ridiculous, for astronauts do not need to pull out their nails, plus if astronauts pull out their nails, then there is no way to complete the tasks performed in space, this matter is a rumor-mongering phenomenon.

For astronauts to need to pull out their nails before going to space, this thing is simply unrealistic, and until now there has been no definite proof, and we. It can also be seen that the ** brackets recorded by astronauts for us in space are all intactThis incident can be proved to be a rumor-mongering phenomenon, which does not conform to reality, but some people have opened their minds to this and have such rumor-mongering behaviors.

Although astronauts are very mysterious and yearning for us, it makes people think that astronauts are a great job, and it also makes people think that living in space is completely different from the earth, and gravity is very strongSome people think that astronauts need to pull out their nails when they go to space, but this idea is really ridiculous, it has not been confirmed, and it is simply a rumor-mongering.

In addition, astronauts must have good physical fitness, and they must pay special attention to their own physical protection, and have a strong body to go to space to complete the mission, which is really unimaginableIf an astronaut pulls out his nails, how will he complete the mission and his work? For this reason, such a statement is really too absurd and really unrealistic.

For astronauts to go to space to pull out their nails. It's really ridiculous, completely unrealisticAnd this is a rumor-mongering behavior, astronauts go to space, there is no need to pull out their nails at all, if they pull out their nails, then it will be difficult for him to complete his future work tasks, plus astronauts need to go to space is a forced physique and a healthy body, if you pull out your nails, then it is not a healthy and physical body at all, for this matter is simply the existence of rumors.
