Explore the secrets at the astronaut training center

  It was a very magnificent building complex: with gray-blue as the keynote, there were about eight or nine buildings, each with no more than three floors, with a green isolation zone in the middle. Because of the different functions, the appearance is also different.
  Through the arrangement of Deputy Chief Engineer Tang Lanxiang, we entered the office building of the Institute of Aerospace Medical Engineering. Director Xu said: “Except for the spacesuit laboratory in the building, the other laboratories are in the office building. I will take you everywhere. Go and have a look.”
  On that day, we witnessed the little-known training, food, shelter, and transportation conditions of the astronauts, and collected some interesting stories in their lives.
  The car first brought us to the electric swing room. There is a box swing inside, which can swing 15 meters back and forth when it swings. It is mainly used for space movement and space motion sickness research.
  Entering the impact chamber, a green iron tower about four stories high appeared in front of you. Its function is to simulate the impact environment of the spacecraft returning to the ground, thereby enhancing people’s impact resistance and studying various protective measures.
  The centrifuge room is a circular building equipped with the largest manned centrifuge in Asia. It is a huge rotating device, which can be extended up and down, or left and right. At its top, there is a 16-meter-long rotating arm. When we approached the centrifuge cabin, a staff member was maintaining the cabin. It must be very uncomfortable for the astronauts to train in it, because they must lie halfway in an arch.
  The planetarium room is a huge vaulted hall. When the lights went out, an extremely beautiful space world appeared in front of you. If the stars are bright or dark, during the training process, astronauts must remember the position and special shape of each constellation, as well as various complicated starry sky maps, in order to recognize the trajectory of the spacecraft to and to follow.
  We also visited numerous simulation training facilities. The low-pressure cabin is a green T-shaped cabin with three parts: working cabin, rest cabin and satellite cabin. When the astronaut puts on the space suit and walks into the low-pressure cabin, the air in the cabin is pumped out, and the astronaut must adapt to this “space” environment without air.
  Among all the simulation training facilities, the one that impressed me most was the simulation training cabin of the “Shenzhou” spacecraft. Since it has just been delivered from the China Academy of Space Technology, the simulation cabin that entered the door is still undergoing “decoration”. The section exposed on the ground has the same shape as the “Shenzhou” spacecraft, but no astronauts are trained in it.
  After watching the training laboratory, Director Xu also led us to visit several supporting laboratories.
  soon as the high-tech “fashion show” arrived at the spacesuit laboratory, I heard the report “The Qi has been fully charged”. The space suit needs to be inflated? It sounds very mysterious. Entering the “fitting room”, researchers have placed a space suit on a large chair.
  The main color of the whole piece of clothing is milky white, with sky blue borders inlaid in some locations. The heart of the clothes has a circular device that can be twisted to adjust the pressure, temperature and humidity in the clothes. There is a thin tube on the right abdomen of the clothes, which is a communication tool for the astronauts; there are two pipelines on the left abdomen, which are facilities for oxygen supply and carbon dioxide emission for the astronauts.
  The whole dress feels good in texture, beautiful and delicate. Researchers said that this spacesuit is an in-vehicle spacesuit. Except for helmets and rubber gloves, the entire spacesuit is made of a special high-strength polyester, which can meet the needs of astronauts during the ascent and return to the ground. Kind of requirements.
  The look of this space suit is quite “cool”, with a one-piece shape and two V-shaped zippers on the chest. Open the zipper, put your legs in, you can put them on step by step. The whole suit weighs about 10 kilograms, and it takes 3 minutes for the astronauts to dress neatly under normal circumstances.
  Regardless of the simple style of the spacesuit, the difficulty of making it is not small. The researchers said that the main difficulty is to solve the problem of how the hands can move freely after the space suit is charged. While talking, he flipped the inflated spacesuit arm up, and this action was easily completed. It turns out that there is a special connecting device between the two arms and the upper arm to solve the problem of flexible movement. This is a whimsical idea that they “secreted” after a long time of thinking.
  Asked about the price and production progress of the space suit, the staff made an analogy: the price of a piece of clothing is about the same as a luxury car. At present, the clothes have been tailored to meet various performance requirements. Now we are waiting for the astronauts to wear it to space for a beautiful “fashion show”.
  Food – space food color flavor the United States
  entered the laboratory production of space food, they feel in the air had a faint smell nostrils, I do not know at the moment in the process where tasty.
  Speaking of astronaut food, the first reaction of many people may be those toothpaste-like foods, but the scientist in charge of aerospace food said: “This kind of food is no longer mainstream. Take a look at our aerospace foods with Chinese characteristics. ”
  Under his leadership, we came to a showroom where dozens of aerospace foods were arranged in glass windows. In addition to a wide variety of canned fish and meat, traditional foods such as bread are rare. The staple foods such as dehydrated rice and curry rice are all packed in silver-gray bags the size of a pocket book; the dishes are also very rich and can be eaten large. Shrimp and other seafood. They are all solid rehydrated foods. When the astronauts eat, they can just pour in hot water.
  Many special dishes with Chinese flavors are made into space food, and try to keep the original flavor as much as possible. For example, the stewed cuttlefish balls, braised bamboo shoots, steamed pork, etc. sealed in a special plastic bag are not much different from the freshly fried dishes after heating.
  The pure drinking water for the astronauts is taken from the underground of the astronaut training center and packed in a special double-layer plastic bag. The strength is quite strong. A flat water bag will not break even if an adult steps on it. As the Chinese love to drink tea, in addition to regular beverages such as orange juice, fashionable modern beverages such as iced black tea and iced green tea are also available, but they are not liquid, but solid beverages like bricks. When you want to drink it, you can’t avoid it. It needs to be blended.
  What if I want to eat fruit? Gourmets have already considered this demand. They freeze fruits such as strawberries, apples, bananas, and peaches at low temperatures to remove water, and then process them through several procedures to make rubber-sized freeze-dried fruits.
  I was lucky enough to taste these “rubber” fruits one by one. Wrapped in tin foil, it is very light to hold. Open the wrapping paper and taste it carefully. Although the fruit has become “dried fruit”, the taste and color are all the same, and the taste is excellent. The instructor proudly said: “Everyone says good food after eating, and astronauts love it. Because our space flight time is short, nutritious food is not very important. The first problem is to’tempt’ astronauts to eat more. ”
  Because of the abundant supply of space food, when I asked to bring some space fruits to my colleagues to taste, the staff graciously grabbed a few handfuls for me.
  Walking out of the showroom, there is a long aisle. Looking down from the railing here, there are small production lines for advanced biscuits, cans, and purified water. Since the astronauts have not yet officially flown, the food has not entered the mass production stage. However, on the three flying spaceships, some foods have been circulated several times as special “passengers”. It has been verified that these delicious foods have withstood the test of the space environment.
  In daily life, astronauts do not eat this kind of food. In order to ensure that they have enough nutrition and physical strength to receive various training, it is said that the standard of food per person per day is more than 100 yuan.
  , Housing – mysteriously out of “Red House” inside and outside
  the astronauts live from Monday to Friday in the space of the city’s most mysterious restricted area – “Red House”, like the “vacuum” isolate the same. Here, they receive relevant training required for spaceflight without any external interference.
  Outside the “Red Mansion”, there are soldiers guarding strictly. Outsiders who want to take a look outside the building or leave a picture will be “very politely” invited to leave.
  Only Saturday and Sunday can the astronauts go home to reunite with their wives and children. Their homes are not like villas, as it is said by the outside world, but six-story buildings, which seem to be nothing special from other family buildings, and their housing area is about the same as that of division-level cadres. Most of their wives work in the same unit as them, and their homes are located in a group of buildings not far from the “red building.” As wives of astronauts, they are as well-trained as their husbands and have a strong concept of secrecy. Outsiders trying to find out from them are destined to be just a fuss, because they have already put a “top secret lock” on their mouths.
  Although living together in a space city, many people have no chance to meet astronauts. Even if they walk out of the “red building” and move in the space city, there are special cars to take them where they need to go. If you go out to perform tasks, in order to protect them as “national treasures”, there are usually police cars clearing the way.
  However, real life is not a vacuum after all. On the day of rest, astronauts will also change into casual clothes to walk or ride bicycles in the space city. If they go to recuperate in other places or go out privately, the leaders of the Institute of Aerospace Medical Engineering and the captain of the flight team will tell them to pay attention to their own safety.
