Tears are visible from time to time, which is bad enough on Earth, but what if you shed tears in space? For example, when you're so shocked by the beauty of space that you cry, what about crying in a zero-gravity environment? Will tears run down your cheeks as they do on Earth?
NASA astronaut Clayton Anderson recounts his experience in space: "I cried several times in space, all because of some very emotional situations. Crying is exactly the same as crying on Earth, except that tears don't fall because there is no gravity.
So, according to the experience of astronauts, tears do not fall in space. But the question is, do tears really form in zero gravity? The lacrimal gland forms in the lacrimal gland, an almond-shaped gland in the lacrimal fossa above the eye socket.
The tear glands produce a thin layer of water in front of our eyes that keep our eyes moist, but they are also the ** of tears. Astronauts in space don't stop crying either, but astronauts sometimes feel dry eyes due to the environment of the ISS. That said, whether it's because of the magnificent scenery on Earth or the extreme loneliness, people in space are sure to cry.
In fact, on the ISS, gravity must be present, but objects in orbit are free-circulating bodies with continuous cycles that avoid falling to the Earth's surface. This makes the object appear weightless。Zero gravity means that the acceleration of the object towards the earth is basically zero.
That is, the orbit of the ISS continues to "fall" due to a phenomenon known as orbital decay. NASA will push again to raise the orbital altitude of the ISS on a regular monthly basis.
Whether in a huge lake or in a cup of coffee, the shape of the liquid depends on the container due to the gravitational pull of the earth. The surface tension in the liquid brings the molecules on the surface closer to each other in space, and if there is no gravity to pull the liquid down, the liquid gathers into the smallest possible shape – a sphere. NASA astronaut Andrew Feustel has a solution to keep fog out of his eyes during a five-hour spacewalk.
Imagine the embarrassment of astronauts in spacesuits and helmets not being able to wipe their eyes away. Luckily, Farstel was able to wipe his eyes with a small sponge glued to the inside of his helmet, which was often used to plug the astronaut's nose when the pressure was adjusted. If there is no sponge in the helmet, the assembled teardrops may damage the astronaut's eyesight.

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

I think his tears will become a small drop of water suspended in the air, and it will not be the same as in life.
-
Tears usually turn into small droplets that move in the air and do not dissipate.
-
It should be suspended in the air and will not fall, after all, there is no gravity in space.
-
I think this tear will float in the air.

In daily life, because of the influence of gravity on the earth, most of the tears fall when crying, but as people explore Zheng Mo outside the earth, they all know that outer space will not be affected by gravity, so what will happen if astronauts cry tears in space?
1. If an astronaut cries in space, the tears usually do not flow down, but gather into water droplets and float in mid-air.
2. Because in space, if there is no gravity, a liquid like tears will slowly gather together to form a sphere, that is, a water droplet, which is very magical.
3. After astronauts land in outer space, they often cry because of excitement or some other reasons, and they can't wipe their tears because they wear a helmet at this time, and these condensed teardrops are likely to damage their eyesight, so they will put a sponge inside the helmet to wipe their eyes when they cry.
In general, if an astronaut cries in space, the tears will float in mid-air and will not fall.

Hello, you still know a lot about aviation, astronauts can't shed tears in space. This is because in space, without gravity and air pressure, tears do not flow from the eyes as they do on the Earth's hailstorm. If astronauts want to shed tears, they need to simulate Earth's gravity and air pressure with special devices such as tear tubes or artificially created tears.

Hello dear dear, in space, astronauts can't shed tears, because liquids and gases in gravity don't behave the same way as the surface of the ball. On Earth, liquids are subject to gravity, and if you cry, your tears will run down your cheeks. But in space, there is no gravity, so the liquid does not flow, but instead forms a sphere-like shape, called the spherical liquid drop effect.
Therefore, even if the astronauts feel sad or sad, their tears will not flow as they do on Earth. Instead, the tears form a tiny droplet that stays in their eyes until they are gently wiped away. Astronauts on a mission to the Celestial Dawn may experience many physical and psychological discomforts, but they must learn to adapt to the space environment, including this particular droplet effect.
This also makes space missions more complex and challenging, requiring astronauts to have greater self-control and adaptability. Expanded knowledge: In addition to tears, many other liquids and gases can also change their behavior due to weightlessness.
For example, in weightlessness, water forms a ball, while oxygen and nitrogen are concentrated in the highest area of the cabin. These special behaviors must be taken into account when designing the capsule and conducting space missions to ensure the safety and health of space pilots.
1. When astronauts enter space, although everyone feels very glorious and glorious, it will also bring a certain threat to astronautsOtherwise, it is brought to the earth by means for burial, so astronauts will leave their last words before entering space. >>>More
Put food in a container like a toothpaste. Squeeze it out and eat it... If you eat like the earth. Things are flying everywhere.
It's true. This is the twin program launched by NASA, and they chose a pair of twins for this experiment. NASA sent her younger brother into space, while her older brother remained on Earth. >>>More
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. >>>More
