Chapter 1198: Interesting space life

However, when Lin Xiaowei, Sun Ming, and Li Yu were on earth, they had also been trained in this area. Otherwise, if the three of them came to this space station, they would only be hungry on the first day.
But even so, the first meal of the three of Lin Xiaowei, Sun Ming, and Li Yu can only be described as a smile.
Three people have eaten this meal and it feels like they have been working all day. Especially when drinking water, I feel particularly strenuous. Although a special feeding bottle is used, it is more difficult to the water in the feeding bottle into your mouth. Because there is no gravity in space. When there is more water in the bottle, you can still normally. But when there is less water in the bottle, it is more troublesome to get them. Because of this small amount of water, it started to float in the bottle. It is not easy to get them.
But sometimes, eating is also a very interesting thing. When eating food like bread, you can also let the bread float in the air and bite it with your mouth. Eating like this is like making a game, which makes people feel particularly interesting.
However, in addition to eating more troublesome, washing your face, brushing your teeth and going to the toilet is a troublesome thing.
Space is a magical world full of charm, and life in space is a magical topic full of charm and curiosity.
The space environment is very different from the earth environment. There is no air, no gravity, and full of dangerous space radiation. Of course, in a closed space station or space shuttle cabin, there is enough air for you to breathe, and good spacecraft shielding materials can effectively block space radiation, but "weightlessness" will bring some trouble to life.
If you go to live in space the way you go on earth, it will definitely make a lot of jokes. For example, when you have a meal, if you carry a bowl of rice, the rice will fill your cockpit one by one, and you may not be able to eat a single one with your mouth open; but when you close your mouth, the rice grains may float into your nostrils and choke you. Half dead. You want to sleep comfortably in bed, but you will find that there is no upper and lower limit in space. There is almost no difference between "lying" and "standing".
The food for astronauts is rich and varied, from the first dozen kinds to more than 100 kinds. Astronauts generally eat 4 meals a day, and the recipes are not repeated within a week. Some people think that the food for astronauts is squeezed and eaten like toothpaste. It must be very boring. In fact, this is the condition of early astronauts, and it is no longer what it used to be.
Now astronauts can eat sausage pie, spicy grilled fish, tempeh broth, biscuits, chocolate, yogurt, preserved fruit, juice and other delicacies in space. American astronauts can even drink their favorite dishes. Coca Cola. However, astronauts cannot eat as they please. They must dine according to the recipe prepared for them by the ground nutritionist.
When eating, the astronauts on the US space shuttle took out the plastic bag marked with the words of the first few days of the meal from the pantry. Each plastic bag contains 7 kinds of food for an astronaut. Space foods are all dehydrated foods. Before eating, you can put the food in a bowl-shaped container, and then use a syringe to inject a certain amount of water into the container, and then put it in the oven for heating. A meal can be "made" in less than half an hour.
The space dining table is specially made. It is magnetic and can hold tableware such as knives, forks, spoons, bowls, plates, etc. The table is equipped with a water cooler and heater. When eating, astronauts must first fix their feet on the floor and fix their body on the seat to avoid floating. Faced with the food on the table, you must not worry, you must pay attention to the coordination of a series of actions of serving bowls, sandwiching rice, opening your mouth, and chewing.
Handle the bowl gently, if the action is too fierce, the rice will float out of the bowl; the rice and vegetables must be decisive, and the clamping must be accurate and clamped. It is best not to pull in the bowl randomly to prevent the food from floating away. Use a fork The effect is best; after the food is clamped, open your mouth quickly and close your mouth quickly, because even the food in your mouth will "fly" without closing your mouth; slow down the rhythm when chewing, and slow chewing The pharynx is good for digestion, and can also reduce the generation and excretion of exhaust gas in the body, and avoid pollution of the astronaut's living environment.
Some people like to talk and talk while eating, but the most taboo thing about eating in space is to talk while eating. Eating and talking will cause the chewed food pieces to fly out of the mouth and float in the dining room or living cabin. Astronauts may choke into the lungs if they do not pay attention to inhale them into the nasal cavity.
Despite the abundant supply of space food, all kinds of variety, and rich nutrition, astronauts generally complain that eating in the sky cannot taste. Scientists analyzed that the reason may not be the food itself, but the astronaut's taste disorder caused by the space environment.
For example, weightlessness makes the nasal cavity congested, which leads to inactivation of taste nerves, changes in saliva secretion and affects the sense of taste, or the sense of taste is affected by the inability to see the color or smell of food. When Chinese-American astronaut Wang Ganjun took the space shuttle to the sky, in order to have a good appetite, his wife made the fried lamb which he usually likes to eat. This food was named "Mrs. Wang's Fried Lamb".
It is true that astronauts sleep in space. They are "confused." One is black and white, and the other is strange sleeping posture. Black and white mean that astronauts orbit the earth in the sky, and the sunrise and sunset in space are determined by the time of the spacecraft orbiting the earth. Sometimes the sunrise and sunset alternate many times within 24 hours. Astronauts cannot follow the life habit of "work at sunrise and rest at sunset" on Earth, so they have to mechanically arrange work and sleep on the hour.
The strange sleeping posture means that astronauts cannot find the feeling of "lying down" in the weightless environment of space. In the earth's gravitational environment, people are accustomed to setting the direction of gravity as "down" and the direction of "sky" as "up", which is what people often say "foot on the earth and blue sky above your head".
However, in a weightless environment, people lose the reference coordinates of "up" and "down". They cannot step on the ground and are surrounded by sky. You can't distinguish between up and down at all. Therefore, there is no such thing as lying down. "One said.
Since astronauts can fall asleep whether standing, lying, or lying on their stomachs, astronauts can sleep in a space capsule, hang on a wall, sleep on a bed, or hang on a beam and lean on a table. sleep.
But most astronauts are not used to drifting to sleep. Once they wake up from the floating sleep, they will have a feeling of falling into the abyss. In order to obtain a sense of security, astronauts generally sleep on a fixed bed or in a sleeping bag fixed on the wall. After the sleeping bag is tightened, a certain amount of pressure can be exerted on the human body, so that people can eliminate the panic feeling of falling.
Some people sleep with their hands or legs outside the quilt. This appears to be a normal phenomenon on the ground, but it is very dangerous in the space environment. With weightlessness in space, a person's limbs will move around without being dominated by the trunk during sleep. A former Soviet astronaut once put his arm outside his sleeping bag to sleep. When he woke up, he suddenly found two big hands floating towards his face, which shocked him. It turned out that the two big hands that fluttered were his own hands.
Surprise is still a trivial matter. If an astronaut falls asleep, his hands of "freedom" and feet of "freedom" accidentally touch any switch or instrument, then the safety of the space capsule and the life of the astronaut will not be possible. Big problem? Therefore, when sleeping in space, be sure to put your hands and feet in your sleeping bag.
Due to the weightless environment of space, seemingly simple washing, brushing teeth, shaving, haircut and washing on the earth have become very complicated and troublesome things in space.
Astronauts wash their faces and brush their teeth. In order to prevent water from floating around, they usually wipe their faces with a wet towel to wash their faces; when brushing their teeth, dip their fingers in toothpaste and rub them back and forth, and then wipe the teeth with a wet towel. Even if it is done. If you brush your teeth like on the ground, the toothpaste bubbles will fly all over the cockpit.
Astronauts generally use electric razors to shave, and they must be very careful when using electric razors. The space capsule is inherently very small, and environmental issues are extremely important. If small scum floats in the cockpit, it will be very difficult to clean up.
Haircuts in space are also not easy, so both male and female astronauts have to cut their hair shorter and shorter before going to the sky. But after a long flight, the hair will grow longer, what should I do? Astronauts must promote the spirit of solidarity and help each other. One has a haircut and the other takes a vacuum cleaner to the cut hair.
Bathing in space is more troublesome. Astronauts have to put their feet in a fixed ring, otherwise their floating body will keep turning somersaults when they are washed by water. The water in the weightless state is all small drops of water, which can easily choke or even choke people to death. Therefore, astronauts must wear breathing masks and goggles when bathing. After taking a shower, the sewage on your body will not flow down automatically, you need to start the water pump and take it away with the air. The water stuck on the canvas cover must also be pumped away. Taking a bath, the real bath time is only 15 minutes, but it takes 45 minutes to clean up sewage and other preparations.
Later, scientists made some improvements to the space bathroom. For example, the bathroom of the Russian Mir space station is like a sauna. After entering, the astronaut heated up for a period of time to make the body sweat, and then wiped it with a wet towel. Due to inconvenience and discomfort, the "sauna room" was changed into a device like a sleeping bag.
When the astronauts take a bath, clean water and shower fluid are injected out of the bag. After scrubbing, the exhaust fan under the bag can be turned on to drain the dirty water. The bathroom on the American space shuttle is a shower cover, and there is also an exhaust fan under the shower cover. When the astronauts take a bath, turn on the shower faucet and exhaust fan, and draw water from above and below, which will form a shower effect like the ground.
Lin Xiaowei, Sun Ming and Li Yu also have wonderful lives in space. Although, they will have some trouble in life. But for a reserve astronaut who has never been to space before, but especially yearns for life in space. No matter how troublesome the situation of life in space is, he is very happy in his heart. After all, this is something that ordinary people are afraid that it is impossible to experience in a lifetime.
These two weeks will soon pass. Lin Xiaowei, Sun Ming, and Li Yu, the three of them, lived in space for the first time. Although something went wrong. But they are all young people, and their adaptability and adaptability are also very strong. They quickly adapted to life in space. And many space experiment missions can be completed in space.
In this way, two weeks later, Lin Xiaowei, Sun Ming, and Li Yu took the moon landing spacecraft and returned to the earth from the space station.
This time in space, Lin Xiaowei, Sun Ming and Li Yu have grown into real astronauts. Although, they have not yet performed the mission to the moon. But the manned spaceflight experiment they participated in this time has already let the teachers and students of Huaqing University know, and they all feel extremely proud of the three outstanding students in their school!
Before, the seven reserve astronauts selected together with Yang Chengwei. Although this time, he was not selected among the three-person team of lunar astronauts. But for the seven of them, it is possible to carry out missions to the moon in the future.
After all, Zhao Zhongyao had already told them. Their mission to the moon is just the beginning of a great era. They will not only carry out this mission to the moon, and they will no longer carry out such missions. In the future, they may conduct multiple moon landings.
Since this is the case. The seven reserve astronauts who were not selected this time. In future missions to the moon, they are still likely to take on this important mission.
Besides, Lin Xiaowei, Sun Ming, and Li Yu have completed this manned space flight experiment. That is very happy. Although this is not a mission to the moon, for them, it feels like they have realized their dream. They have grown into a real astronaut.
This time after the end of the manned space experiment mission. Zhao Zhongyao and the others began to prepare for the real moon landing plan.
However, before the real moon landing plan. They still have to do a big thing. It is to launch another spaceship to the moon. This is a large cargo ship. It is not used to take astronauts, but to transport astronauts to live on the moon and all the living supplies needed.
As the saying goes, ‘soldiers and horses have not moved, food and grass go first’. This is the same for space programs. I want astronauts to conquer space. Before the astronauts do not take action, they must first prepare the supplies needed for the astronauts to live in space.
Zhao Zhongyao decided to divide the moon landing plan this time into six steps to complete the moon landing plan this time. First of all, the astronauts must be sent to a space station in a 1,000-kilometer synchronous orbit of the earth.
The astronauts who land on the moon there will take a short break and check the moon landing equipment. Then continue to take the spacecraft and fly to the moon.
