It can be seen how fierce the selection of astronauts is, so the advantages of political discipline that have only entered now are not very many.

The physical examination took a week, and unlike the previous physical examination, this time it was exhaustive, and it seemed that all possible means were used to conduct a separate examination of him from head to toe, and there were various examinations every day, doing clinical, and in a period of more than ten days, it made Zhengji feel that his whole body organs had been examined.

The results of the examination were outstanding! It should be said that they were the first, and all of the physical qualities of Zhengji were the first! In fact, they were the first without any doubts! It was so good that the medical personnel in charge of performing physical examinations were surprised, and it was not that they had never seen pilots with excellent physical fitness, and it could even be said that the subjects of the daily examinations were all from the upper echelons of human physical fitness, but even so, Zhengji gave them enough shock.

Masaki even remembers that after the results of his examination came out, the doctor looked at him with enthusiasm like a guinea pig.

After that, only the first stage of the inspection has been completed, only the inspection of the pilot, you must know that the next stage of the pilot is the astronaut, the first to carry out the pilot's inspection, and then pass before the further astronaut test, the pilot's inspection has been very strict, such as the eyes, nose and other organs are very high, for the balance ability is more concerned, and the astronaut's inspection, on this basis, is more strict, which contains special factors to check.

After completing the so-called "ordinary" inspection, which was not ordinary at all in his eyes, Masaki came to the space base and conducted a special function inspection.

This is different from the previous examination, it is a further difficult selection, mainly depending on whether the person being tested has "aerospace physiological function", the so-called aerospace physiological function, is the essential difference between astronauts and ordinary people in the body, which is an indispensable natural threshold.

Zhengji's vision was originally broad, but in the testing center of the space center, it was still like Grandma Liu entering the Grand View Garden, and many instruments and equipment and methods were unprecedented for him.

For example, the centrifuge is used for astronaut training and testing.

The subjects are subjected to an overweight of about seven times their body weight in a centrifuge that spins at a rapid pace, and tests the endurance of various overweights in the chest-dorsal and cephalop-pelvic directions, which is the most important test to develop the astronaut's ability to withstand loads.

There are two biggest environmental challenges to space flight, one is being overweight and the other is weightlessness. The spacecraft needs to be sent into a certain orbit to overcome the earth's gravity, which needs to reach a certain speed, that is, the first cosmic velocity, and the astronauts will bear the overload caused by acceleration on the spacecraft, which is overweight.

In fact, being overweight is not uncommon in life, not only in aviation, but also in aerospace flights. When a fighter plane maneuveres at high speed or does aerobatic maneuvers, the overweight G value will often become larger, but this time generally lasts for a short time, but aviation is different, and the superweight value of the spacecraft will reach a very high level when it accelerates before entering the orbit and when it returns to the ground after completing the mission! The duration will be longer! If the spacecraft returns to the earth in a ballistic manner, the overweight value will even reach more than a dozen Gs that ordinary people can hardly bear! It is equivalent to the pressure of more than ten times the weight of human beings! This kind of pressure can cause breathlessness or shock, loss of will, black vision, and even directly affect the life of astronauts!

Imagine what it's like to ride a roller coaster, and the astronauts will endure a hundred times more than that!

The function of the centrifuge is to test and train the astronauts' endurance capacity on the ground! On the rapidly rotating centrifuge, it will cause different G-class overweight feelings.

Masaki stood in front of the centrifuge, which was more than eight meters long and shaped like a cylinder with a long arm.

Masaki saw with his own eyes that one of the pre-selected team members went up to the test before him.

In the high-speed rotation, the camera monitored in the centrifuge showed that the facial muscles of the trainer began to deform and sag, the muscles seemed to be stretched, and the whole face was shown with a high forehead, with the acceleration of speed, the blood pressed to the head, and the face became red, and when training in the direction of the head and basin, the blood rushed to the lower limbs, and the trainer began to appear ischemia and dizziness, rolled his eyes, his vision became very poor, and even he couldn't see things clearly in pitch black, resulting in black vision.

The trainee's heart beat faster in the cabin, and his breathing seemed to be extremely difficult, and when he reached eight G's overweight, it was obvious that he seemed to have exhausted all his strength.

The rapid spinning centrifuge was pressed the pause button by the team members inside in less than a minute, and when he came out, his face was pale, he had to be supported when he walked, and the sweat had soaked his training clothes, and he vomited to the ground after walking less than two steps, and the tears were blurred, on the one hand, the physical pain, and on the other hand, the psychological unwillingness and regret after failure.

"Fail, next," The staff next to him looked at the team members who failed to test without expression, and did not seem to have the slightest sympathy, this training is recognized as the most painful one, not only to pay a huge amount of physical strength and energy, but also full of danger, if you can't bear it, you must not be able to endure it, the trainees and outside observers will always observe and prepare to stop training, the selection of astronauts is so cruel, he has seen too many losers, this is responsible for their lives, but also responsible for the aerospace industry.

"Go ahead, try it," Major General Chen Yuxuan, who came with Masaki, patted Masaki on the shoulder and said with a smile, he didn't have the slightest nervousness and was full of confidence in Masaki.

Masaki nodded and walked over to the machine.

The person in charge of recording and adjusting the instrument was a young girl who obviously recognized Masaki, and was very surprised and novel by Masaki's arrival, while * the machine, she secretly looked at Masaki from time to time, her face was red, and she didn't know what she was thinking.

"There's an emergency shut-off button in the cabin, so if you can't hold on, you can press it," explained the young female staff member while adjusting the button next to Masaki.

Adjusted to the right height and weight for Masaki, Masaki stepped into it, fastened a special seat belt, and nodded outside the centrifugal cabin to signal that it was time to start.

"This is the recruit you brought?" In the data observation room outside the cabin, a middle-aged man seemed to be very familiar with Chen Yuxuan, and asked casually as he watched Zhengji sit in it.

"Well, the physical fitness is the best I've ever seen", Chen Yuxuan nodded and poured a glass of water.

"It's good to take a test and you can understand, but I'm afraid that this height won't be able to enter the fence in the end," the man said, glancing at the slowly starting centrifuge.

Chen Yuxuan nodded, the only problem with political discipline is probably the height problem, you must know that the prescribed height should be about 172, but his height of 185 is nearly 13 centimeters, not that there is anything wrong with the height itself, but there are some restrictions in aviation, the height is too high, the relative blood from the foot to the brain is longer, the heart needs more strength to pump the blood to the whole body, and in a few G overweight, any burden on the heart will become the last straw that overwhelms the camel, and the shooting of the space capsule may also be controlled at the right size due to cost and technical reasons, and the height is too high or it may look aggrieved in the cabin。

"I know all of this, but maybe there will be a miracle if you try?" Chen Yuxuan said.

During the conversation between the two, the centrifugal cabin has begun to rotate, faster and faster, the monitor shows that the overweight has reached the level of four Gs, the average roller coaster only has two Gs, and the face of the Masaki in the cabin is as usual, as if he has no feeling at all, and in Chen Yuxuan's monitoring, he even feels as if he is observing the centrifugal cabin.

"Well, it's pretty good," the middle-aged researcher nodded, the average person will be a little painful and uncomfortable when using the centrifuge cabin for the first time, and the 4 Gs can be so extraordinary that they can behave like this.

"Continue to increase the eccentricity," the man gestured to the staff.

5G, 6G, 7G, the staff near the centrifuge in the aviation center gradually shifted their attention to the centrifuge, the overweight of the centrifuge has reached 8G! Even among the pilots, it is already highly overweight! Ordinary people can hardly bear even a second, but the political discipline in the centrifuge cabin, except for a little pale, does not show any discomfort! The face is as usual with his eyes open and looking at the rapidly rotating walls around him.

In the observation room, Chen Yuxuan and the middle-aged man no longer spoke, but looked at Zhengji on the screen with their mouths slightly open, if they didn't know where Zhengji was, they would even suspect that Zhengji was asleep? How could it be so calm, so normal? Unlike other people's deformation of skin and muscles being dragged under high weight, Zhengji's face is difficult to see deformed, as if it is gel, thanks to his dense body that has been modified by the virus and the writing wheel.

Chen Yuxuan and the middle-aged man both felt incredible, it was not how high the overweight was in Zhengji, although it was eight Gs, most of the candidates for astronauts could withstand forty seconds, which was not surprising, but you must know that unlike the astronauts who were candidates, they were all senior pilots before, and they often carried out overweight, and this is the first time that Zhengji has carried out this kind of experiment!

The first time, I was able to reach eight Gs, and it seems that my condition is surprisingly good, this is the only one!

Ten seconds, twenty seconds, thirty seconds, forty seconds!

The centrifuge has been spinning at a high speed of 100 kilometers per hour and maintaining a speed of 8 G's for a full 50 seconds! This is already more than the usual training capacity of astronauts! However, the expression on the face of the cabin remains the same!
