Beijing, Astronaut Training Center.

This vast aerospace research institute with a history of more than 50 years has been opened to private individuals for the first time and welcomed its first 'customer' to participate in training.

As a black car drove through the gate and stopped in front of the control center building, curious eyes instantly came from all directions.

Wei Kang stepped out of the car, followed by Jian Lian Yun.

As soon as the two of them stood still, they saw a figure walking forward quickly.

This is a middle-aged man in his early forties, with a resolute face, a calm temperament, and a hint of restraint in his enthusiasm. He reaches out his hand from a distance.

"Mr. Wei, I am Su Yang, who is in charge of reception, and I am also an instructor of astronauts. Nice to meet you."

Wei Kang smiled slightly and said very politely: "Nice to meet you. Nice to meet you. This is my wife Jian Jianyun. I'll leave this training to you."

After the three of them chatted for a while, Su Yang took them around the entire training center to familiarize themselves with the venue and prepare themselves mentally for the first training.

"It's a bit late today. Let's take a rest and get familiar with the environment. We will start formal training early tomorrow morning."

Su Yang explained the specific itinerary one by one: "Generally speaking, astronauts must undergo three years of rigorous training before entering space. For non-professionals, such as scientists participating in aerospace, the time will be shorter, but it also requires

About a year and a half.”

"Of course, their training content is relatively large. Mr. Wei, you will only stay in the space station for a few days. You don't need such long-term training. You only need to conduct aerospace-related training."

"It mainly includes three aspects, the first is weightlessness and overweight training, the second is aerospace living environment training, and the third is emergency life-saving training."

"The time is three months, seven days per month, and then there will be another 14 days of intensive training before the rocket is launched."

"Because this week is the first training, it is mainly general training, including a four-day flight knowledge course, such as astronomy, geography, flight mechanics, rocket and spacecraft construction, necessary medical knowledge and rescue techniques, etc."

Having said this, he smiled: "Both of them are professionals in the pharmaceutical industry. They should be able to get full marks in medicine."

Wei Kang asked curiously: "Why are there still exams?"

Su Yang nodded: "During the intensive training before the rocket launch, the knowledge courses will be subject to a final assessment. Only those who pass can proceed to the next step."

Jian Jianyun looked forward to it, a little eager to try: "It's been a long time since I took the exam, so I'm really looking forward to it."

"Then there will be three days of simulation training, including comprehensive drills on spacecraft landing training, docking training, exiting the cabin, activities inside and outside the cabin, recovery and life-saving."

"Of course, the first simulation training will not be too in-depth. It mainly allows the two to become familiar with the aircraft and flight procedures, and experience the weightless environment."

"Only in the second training will in-depth professional training be carried out, mainly to carry out movement exercises in weightlessness to enhance the two's tolerance to overweight, and at the same time improve their adaptability to the aerospace environment and life."

"The third training was similar to the first two, except that there were no theoretical knowledge courses, and lifesaving training on ejection seats and lifeguard towers was added. Of course, there will also be wilderness survival training."

Jian Jianyun asked in surprise: "Didn't it land directly at the space center? Why is there still wilderness survival training?"

Su Yang chuckled and said: "That's right. This is to deal with the emergency return of the manned spacecraft, or some special circumstances that occur on the way back. At this time, the return capsule may land in an uninhabited place, such as the vast sea or virgin forest.

Or deep in the desert.”

"If something happens, you will not be able to communicate with the rescuers on the ground in time, so while waiting for rescue, you must use your own life-saving knowledge and survival skills to save yourself."

"In the 1960s, when a manned spacecraft of Mao Xiong returned to land, it made an emergency landing in the birch forest of the Ural Mountains due to a malfunction. The two astronauts could only write a distress signal in the snow while carrying it with them.

An emergency pistol to protect against wolves and bears, and a fire to keep out the cold.”

"In the end, the well-trained astronauts relied on their excellent survival skills to get out of the predicament and waited until rescuers arrived."

"That's it." The two of them looked at each other and suddenly realized.

"Don't worry too much. Mastering these knowledge and skills is mainly to improve your life-saving ability and psychological quality, so as to be prepared. In fact, emergency situations in which astronauts land in wilderness, sea and desert are almost non-existent."

"I understand." Jian Jianyun couldn't help but sigh: "It seems that it is really not easy to be an astronaut. We go up for three days and undergo three months of training. They have to stay for several months and need to undergo three years of training."

Training requires a lot more learning than us."

Wei Kang nodded in agreement: "It's true, it's all very hard. It's a devilish training. It's really not easy to become an excellent astronaut."

The next day, the two officially started training.

The flight knowledge class was okay and not too difficult. Both of them are highly educated people with strong learning ability and memory. They memorized all the knowledge points without much effort.

Not to mention medical knowledge and first aid techniques.

These are instincts engraved in their bones. They already know that many steps and technologies need to be changed just because the environment has changed from the earth to space.

On the fifth day, weightless training begins.

Su Yang took the two of them to a huge water tank early in the morning.

The water tank is 10 meters deep and 23 meters in diameter. From a distance, it looks like a giant.

This is a neutral buoyancy tank that provides astronauts with simulated weightlessness training.

The space station underwater training model lies quietly at the bottom of the water.

Extravehicular activity training can be carried out here, especially extravehicular operations such as extravehicular walking, extravehicular assembly and maintenance, with outstanding results.

Of course, it is impossible for Wei Kang and the others to perform such advanced operations during their first training. This time they are just experiencing a weightless environment.

The three of them changed into tank training clothes, entered the tank, slowly dived, and came to the space station model at the bottom.

This model is made at 1:1 scale with the space station and is very realistic.

Wei Kang was floating in the cabin, and everything in front of him felt novel and immersive, as if he had really arrived at the space station.

He was very excited, touching here and there, with a smile on his face.

Jian Lian Yun was not so excited, but he couldn't help but look around, as if his horizons were wide open.

Su Yang smiled at the side. He understood very well the excitement of ordinary people seeing a living space station for the first time. Even if it was just a model, it would be an unforgettable experience.

When the two people's emotions slowly calmed down, the training began.

As an instructor, Su Yang's task is to decompose each movement, refine each posture, and help the two master body movements, posture control, and activities inside and outside the cabin in weightlessness.

Including opening and closing the cabin door, exiting and entering the cabin, walking inside and outside the cabin, etc.

The training lasts 3-4 hours and requires a lot of physical exertion because it is in the water.

By the time it was over, Wei Kang already felt a little tired, and Jian Jian Yun was even more pale and out of breath.

"Haha, it's my first training. I'm definitely not used to it. It needs a process of adaptation. This training is equivalent to moderate physical labor on the ground. It's normal to feel tired."

Su Yang said thoughtfully: "Take a good rest at noon, and you can start later in the afternoon."

Wei Kang hammered his sore thigh and asked, "What training is this afternoon?"

Su Yang smiled mysteriously: "You will know when the time comes."

After lunch, the two took a nap in the room for a while, and then came to a laboratory.

On one side of the laboratory is a control desk, and on the other side is a sunken space. There is a very strange piece of equipment that looks like a metal ladle.

The handle of the spoon was nailed to the ground by a metal rod, and the spoon continued to rotate around the metal rod, making a loud buzzing sound.

Wei Kang stood on it, looked at it for a while, and felt a little dizzy.

"This is a manned centrifuge. There is a manned cabin next to the spoon. Once you sit in it, you can experience the feeling of being overweight."

Su Yang pointed to the centrifuge: "This is overweight endurance and adaptability training. The purpose is to enable astronauts to withstand huge overloads, stay awake, and operate correctly during the ascent and descent of the spacecraft."

"There are people inside now who are experiencing an overweight state."

Jian Lian Yun looked at the high-speed rotating centrifuge and couldn't help but be stunned. After a while, he asked: "How big is this gravity?"

"8 times the acceleration due to gravity."

"8 times!" Jian Jianyun suddenly exclaimed: "Oh my God, can we withstand such a heavy gravity?"

"No, the general population can only withstand 3-4 times the acceleration of gravity at most, so the gravity you bear will gradually increase, starting with 1x and 2x."

Su Yang smiled and explained: "The eight gravitational accelerations are for astronauts and do not apply to you. Moreover, in this case, astronauts must complete various technical actions, which is quite difficult."

While talking, the centrifuge slowly stopped.

After a while, an astronaut walked out, rubbing his face vigorously with his hands as he walked.

Wei Kang looked over and was startled. He saw that the other person's face was covered with tears and the muscles on his face were also somewhat deformed.

Su Yang came over and explained in a low voice: "Under 8 times gravity, the facial muscles will be severely deformed due to the strong pulling force, tears will flow out unconsciously, and you will also feel difficulty breathing, which is quite uncomfortable.

, it’s best for most people not to try it easily.”

The two nodded at the same time, feeling a little uneasy.

This centrifuge looks uncomfortable. Even with three or four times the gravity, it seems that it will make people very uncomfortable and leave deep memories that will last a lifetime.

Next, Wei Kang personally experienced the crazy power of a manned centrifuge.

When it doubled or tripled, he could still hold on. When it slowly increased to four times, he could no longer control his facial expressions. As for the snot and tears, they burst out like they were free of charge.

come out.

"Stop! Stop! I have to slow down!" After coming out, Wei Kang felt dizzy. Fortunately, someone helped him, so he didn't fall to the ground.

Jian Jian Yun was no better than him. When he came out, his face was pale, his eyes were straight, and he had to be helped to walk.

The two of them were sitting on the chairs, both still feeling dizzy.

"It's so, so uncomfortable. I almost suspected that I would have a cerebral hemorrhage." Jian Jianyun gasped.
