Super technology leader

Don't try or know, space is amazing.

A group of people had a great time playing in the more traditional space station. Among them, Du Kangsheng felt the most, because he was the only one in this group who had stayed in earth orbit and had completed the task of operating equipment in a weightless state.

During the period, Tang Chao also questioned him, and he also truthfully reported.

Because there is still a certain difference between the orbital shuttle and the space station, there must be a gap, but in comparison, the model exercises he did on the ground before are not at the same level as now.

"Boss, the simulation state of the virtual reality space is very realistic. In my previous exercise, I had a relatively hanging indicator called'hand feeling'. As long as it is practiced, there will be no operation errors even if you close your eyes, but because of the ground and The difference in space gravity, this project is very difficult to practice."

"Today's virtual space practice gave me a big surprise. Whether it is gravity index, button material, interaction state, or tactile feedback, etc., I feel the feeling of operating in real space."

"As a training device, it is perfect, but if there are any differences and shortcomings, it is probably that the tactile feedback is insufficient. All the feelings are similar, but it always feels like something is missing, like eating a braised lion. The head, half the meat and half the noodles, although it has an inner taste, it is almost half the meat after all."

"And if you look closely, you can still find that this space station is not so real, just like playing a game, don't look at the modeling becoming more and more real, but there is always a certain difference from the real reality."

After hearing Du Kangsheng's report, Tang Chao nodded, "You feel right. After you have gone through a process, we will tell you in detail."

Du Kangsheng nodded and continued to lead a group of "trainee astronauts" to experience a wonderful virtual space journey.

However, the entire process cannot be in space. Since Tang Chao said that the first piece of wood was also part of astronaut training, he would definitely let them see it.

And they are just doing an experience this time, and only a few hours, many processes will be shortened, after all, their bodies are still lying on the bed, after a few hours, they have to eat and go to the toilet, otherwise it is prone to problems.

In addition to the floating experience in the space station, Tang Chao also arranged for them to perform physical exercises in the earth environment.

As a basic condition for a person's survival, physical fitness is also indispensable in the training process of astronauts.

After all, only a healthy and strong body can withstand the harsh environment of space, and it will not cause physical problems in a day or two. Then take an expensive spacecraft to return to the ground, and the ground will have to launch a manned rocket to supplement the experimenters.

In addition to basic physical training, other aspects of tolerance must also be considered. Therefore, in order to comprehensively improve the physical fitness of astronauts and improve the adaptability and tolerance of astronauts to special environmental factors, it is necessary to conduct special aerospace training for astronauts. Exposure and stimulation of environmental factors, such as overweight, weightlessness, stimulation of vestibular organs, noise, high and low temperature, etc.

The purpose of overweight adaptability training is to allow astronauts to adapt to the overweight environment during spacecraft launch and return, and to enhance the astronaut’s ability to resist overweight. The training method mainly uses centrifuges to simulate the overweight curve during the take-off and return of the spacecraft. Chest-back confrontation exercise training and head-basin endurance maintenance training.

In order to reduce the incidence of space motion sickness, vestibular function training is also required.

This kind of training will use swivel chairs, swings and other rotating and swinging equipment to generate linear acceleration and Coriolis acceleration, or move the astronaut’s head in a weightless aircraft to stimulate the vestibular organs of the subject to improve the tolerance of the vestibular organs ability.

Other adaptation training for special environmental factors include aircraft flight training, parachuting training, vibration, noise experience, crew cabin atmospheric environment experience, and isolation environment experience.

Naturally, these physical tests can't be realized in virtual space, but Tang Chao can let them feel mentally, and even accelerate the whole process of feeling.

For example, for physical exercise, running is definitely getting more tired as you run. If humans want to break through themselves, not only must the body adapt to the feeling of fatigue, but also the spirit can withstand fatigue.

In reality, you can only run according to reality, running a few kilometers or ten kilometers, while in the virtual world, you only need to modify a few values ​​and you will feel tired after running five kilometers after running 50 meters. .

This feeling of fatigue impacts the brain's nerves, constantly sending out the signal of "want to rest". After several times, the brain will adapt to this signal and it will develop resistance.

Then after you go out, your body "persuades you" to rest when you run again, you can resist with this familiar feeling, and then break through yourself, let yourself run further, squeeze your physical potential, and make yourself more strong.

These physical trainings, although virtual space cannot directly affect the body, it can at least give astronauts a "mental preparation", so the real "mental preparation" is its strength.

Psychological training is an essential part of astronaut training.

Because performing space missions requires leaving the environment we are familiar with, and this environmental change has a great psychological impact.

Especially in the early space activities, the living environment provided by the manned spacecraft to the astronauts was not very good, whether it was space or food, stayed in such a small environment for a long time, and had to endure the noise caused by the operation of the machine 24 hours a day. , It feels quite difficult.

And if this feeling affects the astronaut’s psychology, it is extremely easy to produce unimaginable consequences.

Being in space is no better than being on the ground. On the ground, you can go out and breathe out if you are annoyed. In space, you can die after the door.

With the advancement of science and technology, although all aspects have improved, the working and living environment of astronauts is still relatively "bad".

Psychological training is to enable astronauts to adapt psychologically to the situation in space before going to the sky, such as adapting to confined and small spaces in advance, adapting to noise, adapting to teamwork, adapting to situations such as screwing a screw an hour, etc., to enhance their psychological The stability.

Because of the increased complexity of the mission, there are several members to complete each flight. It is scientifically proven that chatting can be relaxing.

Of course, the premise is that you cannot chat with the topic terminator.

Human beings, as social creatures, need the company of the same kind very much. If they are alone all the time, the time of problems is definitely faster than the time of problems in groups.

Even those homeboys who claim to be unable to go out often chat with sand sculpture netizens through the Internet. Otherwise, if you really stay alone, it is easy to get psychological problems.

It just so happens that space missions require the cooperation of multiple people, so apart from the initial limitation of space technology that allows one person to enter space, the subsequent missions are at least two-person teams.

In order to reach the level of "inspiration" among members as soon as possible, early team training and running-in has become an important part of psychological training.

Practice has proved that the training of the entire group of members plays a very important role in improving their working efficiency in space.

General astronauts spend a long time in joint training. Short-term space missions are no less than half a year, medium-term space missions take one year, and long-term space missions take more than two years.

The most important thing is that they can only train on the ground before the model. After entering space, they have to lose weight and have to run in for a period of time. Generally speaking, the time is longer.

In virtual space, you can skip many steps and let the astronaut team train in a "space-like" environment. Since space missions are to be performed, the test must of course be conducted in "space".

If there are astronauts who cannot withstand the psychological pressure and directly open the hatch and destroy them, there is no way in reality, so they can only do strict simulation on the ground.

It's different in the virtual space. Only some data is destroyed when the door is opened. With the protection of safety equipment, the members will only feel a little pain, and there will be no accidents themselves.

Even the pain of death from exposure to a vacuum environment can be eliminated. After all, it is a feeling of death, and the psychological pressure on the members will be greater.

For training, just keep the feeling in the cabin.

Of course, if after safe scientific research, the slight feeling of death can be studied to make people cherish life more, it may be reused.

The most important thing is that this kind of realistic space environment can find out the unstable factors in advance, and then run in several times to quickly form a team that is really suitable for the task.

This is the function of nerve-diving virtual space.
