I don't know, space is amazing.

A group of people had a lot of fun in the more traditional space station, and Du Kangsheng felt the deepest, because he was the only one in this group who had been in the earth's orbit and completed the task of operating equipment in weightlessness.

During this period, Tang Chao also asked him, and he also made a report truthfully.

Because there is still a certain difference between the orbital shuttle and the space station, it feels like 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, I have a more suspenseful indicator called 'feel' in the previous practice, as long as it is practiced, even if you close your eyes, you will not make a mistake in the operation, but because of the difference in gravity on the ground and in space, this project is very difficult to practice."

"Today's virtual space exercise gave me a big surprise, whether it is the gravity index, button material, interaction status, or haptic feedback, etc., it all makes me feel the feeling of operating in real space."

"As a training device, it is very perfect, but if there is any difference and deficiency, it is probably the lack of tactile feedback, all the feelings are very similar, but it always feels like something is missing, just like eating braised lion's head, half meat and half noodles, although it is an inner taste, but after all, it is half less meat, almost meaningful."

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

After listening to Du Kangsheng's report, Tang Chao nodded, "Your feeling is right, after you finish 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 whole process can't be in space, since Tang Chao said that the forest at the beginning is also a part of astronaut training, then they will definitely be allowed to see it.

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

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

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

After all, only a healthy and strong body can withstand the harsh environment of space, so that there will be no physical problems in a day or two, and then return to the ground in an expensive space vehicle, and another manned rocket will be launched on the ground to supplement the experimenters.

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 expose and stimulate astronauts to special environmental factors in aerospace, such as overweight, weightlessness, stimulation of vestibular organs, noise, high and low temperatures, etc.

The purpose of overweight adaptation training is to enable astronauts to adapt to the overweight environment during spacecraft launch and return re-entry, and to enhance the astronauts' ability to resist overweight.

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

This training uses rotating and swinging devices such as swivel chairs and swings to produce linear acceleration and Coriolis acceleration, or the astronaut's head movement in a weightless aircraft to stimulate the vestibular organs to improve the tolerance of the vestibular organs.

Other special environmental factors adaptation training includes aircraft flight training, parachute training, vibration and noise experience, cabin atmospheric environment experience and isolation environment experience.

Naturally, these physical tests could not be realized in the virtual space, but Tang Chao could let them feel spiritually, and even speed up the entire feeling process.

For example, if human beings want to break through themselves, they must not only adapt their bodies to the feeling of tiredness, but also make their spirits able to resist fatigue.

In reality, you can only run as it is, running a few kilometers, more than ten kilometers, and in the virtual world, as long as you modify a few values, you can run five kilometers after running fifty meters.

This feeling of exertion hits the nerves of the brain, constantly sending out signals of "wanting to rest", and if you come a few more times to get the brain to adapt to this signal, you will have resistance.

Then when you go out, your body "advises" you to rest when you run again, you can resist with this familiar feeling, and then break through yourself, let yourself run farther, squeeze your physical potential, and make yourself stronger.

These involve physical training, although the virtual space cannot directly act on the body, but at least it can allow astronauts to have a "psychological preparation", so for the real "psychological preparation", is its strength.

Mental training is an indispensable part of astronaut training.

Because space missions require leaving the environment we are familiar with, and the psychological impact of this environmental change is great.

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

And if this feeling affects the psychology of astronauts, it can easily have unimaginable consequences.

In space is not as good as on the ground, you can go out to breathe when you are upset on the ground, but in space, you 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 "harsh".

Psychological training is to enable astronauts to psychologically adapt to the situation in space before they go to space, such as adapting to confined and narrow spaces in advance, adapting to noise, adapting to teamwork, and adapting to turning a screw an hour, so as to enhance psychological stability.

Because of the increased complexity of the mission, each flight is completed by several crew members, and it is scientifically proven that chatting is relaxing.

Of course, the premise is that you can't chat with the topic buster.

As social creatures, human beings need the company of their kind very much, and if they are alone all the time, then the time for problems is definitely faster than the time for group problems.

Even those otaku who claim not to go out often chat with sand sculpture netizens through the Internet, otherwise it is easy to have psychological problems if they are really alone.

It just so happens that space missions require multi-person cooperation, so except for the initial restrictions on aerospace technology to allow one person to go into space, the subsequent missions are at least two-person teams.

In order to make the members reach the level of "heart-to-heart" as soon as possible, the run-in of team training in advance has also become an important part of psychological training.

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

Generally, astronauts train together for a long time, with short-term space missions taking no less than half a year, medium-term space missions taking one year, and long-term space missions taking more than two years.

The most important thing is that they can only train on the ground in front of the model before, and after entering space, they have to run in for a period of time after being weightless, and the overall time is longer.

In the virtual space, you can skip many steps directly, and directly let the astronaut team train in a "space-like" environment, since you are going to carry out a space mission, then the test must of course be carried out in "space".

If there are astronauts who can't withstand the psychological pressure and directly open the hatch and destroy it, there is no way at all 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 hatch is opened, and with the protection of security equipment, the members will only feel a little pain, and there will be no accidents themselves.

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

If you want to train, you can just keep the feeling in the cabin.

Of course, if it is safe to study that a slight feeling of death can make people cherish life more, it may be possible to use it again.

The most important thing is that this realistic space environment can find out the unstable factors in advance, and then run in a few more times, and quickly assemble a team that is really suitable for the mission.

That's where neural infiltration virtual spaces come in.
