In space, astronauts can t shed tears, why?

In space, the reason why astronauts can't shed tears is because there is no gravity in space, he is not like the earth we live in, the earth has gravity, for example, ripe apples will fall to the ground, and our tears can also fall on the ground. At the same time, we also know that astronauts will be in a state of weightlessness when they go to space, which means that astronauts will have great difficulties in every step in space, and other accidents may occur. <>

Fundamentally speaking, human beings have been studying space since ancient times, but space is too big, and its mysteries are also very deep and many, so we are still in the preliminary stage of space exploration. Astronauts can't shed tears in space, this is not to say that astronauts won't cry after they go to space, it's not like this, "can't shed tears" here actually means more specifically that astronauts can't shed tears in space, they can't flow on their faces, they want to cry on the earth. <>

Moreover, not to mention whether the astronaut can shed tears in space, just say that the astronaut cries in space, and the tears are swirling in the eye sockets, as long as the tears come out, this is very dangerous for the astronaut. Because we all know that astronauts go to space in thick spacesuits, which they can't take off at all, and they also have to wear special helmets. If the astronaut cries in space and tears roll in the eye sockets, then this will definitely make the helmet full of fog, and the astronaut's own eyes will be a little unclear, which is dangerous to the astronaut, after all, all words and deeds in space can only be completed by very large force.

In space, astronauts also belong to a state of weightlessness. <>

Human exploration and research in space is still continuing, and there are too many mysteries in space waiting for us to unearth.

Crying in space, what would tears look like? Netizen: Don't cry.

It's okay to shed tears, but it's more dangerous to shed tears. If an astronaut weeps in space, due to the lack of gravity, the tear will turn into a water balloon near the eye, and if you are not careful, it will be suffocated if it enters the nose or mouth.

Because the environment is gravityless, the tears that flow out will accumulate more and more near the eyes, and finally form a lump, at most it will stick on the face, but it will not flow.

In the microgravity environment, tears are trapped in the eyes, so astronauts shed tears in space, then the tears will collect around the eyes and eventually form a large balloon of water.

The microgravity environment causes tears to remain in the eyes, so if a person weeps in space, the tears will collect around the eyes and eventually form a large water ball, which is very dangerous for astronauts.

Teary-eyed eyes can often be seen, and this is already on Earth.

Bad enough, but what if Dig Dou wept in space? For example, if you are moved to tears by the beauty of space, what will happen to your tears in a zero-gravity environment? Will it be like on Earth, where tears just run down the cheeks?

NASA astronaut Clayton CAnderson recounts his experience in space: I cried a few times in space because of some very emotional situations.

Crying is exactly the same as on Earth, except that tears do not fall because there is no gravity.

So, according to the personal experience of astronauts, tears do not fall in space. But the question is, do tears actually form in zero gravity?

Astronauts in space don't stop crying either, although astronauts sometimes feel dry in their eyes due to the environment on the ISS.

In other words, people who go to space are bound to shed tears, whether it's because of the magnificent beauty of the Earth or the extreme loneliness.

How does gravity change in space?

In fact, on the International Space Station in space, gravity is certainly there, but objects in orbit are in continuous cyclic free-fall motion to avoid falling to the Earth's surface. This makes the object appear weightless, and zero gravity means that the acceleration of the object towards the earth is basically zero.

That being said, the orbit of the ISS is constantly decreasing downward due to a phenomenon known as orbital decay. NASA conducts periodic re-propulsions once a month to raise the ISS's orbital altitude.

NASA astronaut Andrew Feustel had a solution to prevent fog from getting into his eyes during a five-hour spacewalk. Imagine the embarrassing situation of an astronaut wearing a spacesuit and a helmet that can't wipe his eyes.

Luckily, Feustel was able to rub his eyes with a small sponge glued to the inside of the helmet, which is usually used to plug the astronaut's nose during pressure adjustment. Without a sponge in the helmet, the accumulation of scattered tear balls can damage the astronaut's eyesight.

So, now we know that tears are spherical in the air. Astronaut Chris Hadfield, in zero gravity, realistically shows how tears form a ball of tears between the eyes and cheeks.

1. In space, due to the absence of gravity, although the tear glands of human beings can produce tears, tears cannot flow. If the lacrimal glands continue to produce tears, tears can accumulate and eventually form a large balloon of water in the eye. This situation is very dangerous in space, and if the liquid is large, it is easy to cause danger to the space station or electrical equipment.

Therefore, astronauts in space, once they have tears, they should be sucked and dried with a towel as soon as possible.

2. Although astronauts can't shed tears in space, other lives can still be carried out normally, but they are a little different from when they were on Earth. For example, astronauts sleep in spacecraft differently than they do on Earth. Because there is no gravity in the air on the Taimo Bridge, the astronauts floated as soon as they lay down.

Therefore, the spacecraft specially prepared sleeping bags, fixed on the wall, and the astronauts got into it when they slept.

Chinese astronaut Nie Haisheng shed tears of excitement in space when he received his daughter's birthday wishes. What does the form of tears look like in space, are they flying?

Xie Daqing, the former chief designer of the astronaut system: Yes, because it is in a microgravity environment, it is different from the shape on the earth. Tears often fall from the corners of our eyes, but in space, tears condense into small droplets and fly out as soon as they come out of our eyes, which is a very interesting scene.

Of course you can shed tears in space, but the biggest difference is that tears don't fall. "If you keep crying, the tears will build up and eventually form a bigger and bigger balloon in the eye," he says, "unless it can go through your nose to the other eye, or evaporate, or it will flow onto your cheek – or you wipe it off with a towel." Otherwise it will always be in your eyes.

This situation is very dangerous in space and can lead to dangerous accidents. If the liquid is large, it is easy to cause danger to the space station or electrical equipment. In the weightless state, larger liquids, such as tears, are also prone to pose a danger to the safety of astronauts if they float in space.

Crying in space, what would tears look like? Netizen: Don't cry.

What happens to shed tears in space? Astronaut: If you don't want to die, you can hold back your tears.

Tears in space, will tears fall? The astronaut revealed, netizens: The state has changed.

Tears shed in space, do tears fall? The astronauts tested it themselves and watched it as an eye-opener.

I think that due to weightlessness in space, the tears that come out of ** do not fall down, but only accumulate into spherical teardrops in the eye sockets.

Hello, you still have a certain understanding of astronautics, astronauts can't shed tears in space laughter. This is because in space, there is no gravity, and tears do not flow out of the eyes as they do on Earth. In addition, astronauts' eyes can also be damaged by radiation in space, so they need to wear special goggles to protect their eyes.

Summary. In space, astronauts are not allowed to shed tears.

In space, astronauts are not allowed to shed tears.

If the lacrimal gland continues to produce tears, it will accumulate in the eye socket and finally form a large water balloon, which is easy to cause the danger of the space station or stool electrical equipment.

Therefore, once astronauts have tears in space, they should be blotted with a towel as soon as possible.
