"Okay, next project, return to Earth."

Tang Chao pointed to a row of spaceships and said to the interface.

"Yeah! I'm finally going to drive the spaceship!"

"I've learned a lot just now, let's see me make a perfect landing for you!"

"Haha, I feel that I must be the first one to land!"

"I not only want to land, I also want to land a ten ring!"

"Just blow, I guess I will only land on a Nine Ring."

Looking at the chattering crowd, Teacher Du strictly abides by Tang Chao's test process and assists.

"Okay, listen to the key points I explained, three people in groups and one return capsule..."

Seeing everyone being arranged into the return capsule, Tang Chao smiled.

"I also want to land safely, or even land a ten-ring. I think it's beautiful. This landing process is used for an accidental demonstration."

The previous space experience and ground training equipment experience were both directly passing through a door, which was the kind of directly cutting the scene. This time, they were able to experience the feeling of re-entering the atmosphere.

After all, after training so much and experiencing so many feelings, you have to fly "really" once.

Astronauts need to operate a variety of instruments and equipment when performing missions, but there are countless equipment in the spacecraft, especially the early spacecraft control interfaces, which are all buttons in the past.

If the astronaut makes a little mistake during operation, especially the pilot, it is very likely that the plane will be destroyed and the person will be killed.

Therefore, before astronauts enter space by driving real aerospace equipment, they must train in various simulation equipment on the ground, so that astronauts can be familiar with the operational procedures and adapt to different environments.

But when it comes to "different environments", the environment in which spacecraft simulation equipment and real spacecraft are located is different, and there is an insurmountable gap here.

It is not even just a problem of the gap, but also various dangers may occur at any time. In the history of human spacecraft, there are also many astronauts who sacrificed their lives in the simulation cabin.

Du Kangsheng had used similar simulation cabins before. Although he memorized the control process and button position, he really entered the cockpit of the orbital shuttle, especially after the orbital shuttle entered space, it felt completely different.

This time when he entered the virtual space for an experience, he experienced both the ground simulation cabin and the "space simulation cabin". Compared with the two sides, good guy, it was really one in the sky and one underground.

Compared with the ground simulation equipment, it provides astronauts with various sensations such as motion feeling, vision, hearing and manipulation load, making astronauts feel that they are really driving a spacecraft. The simulation cabin of virtual space is called a real simulation cabin.

It directly simulates a complete set of projects such as simulating the takeoff of the spacecraft, how to control the entry and attitude, space docking, space maintenance and cabin exit, and the entire process made him, a real astronaut, think he was driving a real spacecraft.

The training effect is quite "explosive".

Well, the spaceship that everyone was riding also exploded after entering the atmosphere.

Fortunately, the explosion was not big, which only caused the spacecraft to deviate from the landing route, and there was also a problem with the speed reduction parachute.

"Ahhhhh, why is my return capsule going around? Where are we going to land?"

"I don't know, I just know I'm going to vomit, um..."

"Damn, don't vomit!"

"Alarm, alarm, drop too fast!"

"There is a large forest below us. I don't know where it is. Where are the other return capsules?"

"I'm the sea here, and I don't know where it is!"

"The white area should be snow! Trough!"

"I'm... so, communication is interrupted!"

……………………

During the emergency return process, manned spacecraft may land in various complex terrain, climate and other harsh living environment conditions, such as cold areas, deserts, mountains, forests, sea, etc., so astronauts must be trained in survival knowledge and skills in these areas to make them familiar with and master the climate change, terrain, sea conditions, animals and plants in these areas, and master the basic principles of survival.

For example, to survive in cold areas, to maintain the thermal balance of the body, to survive in primeval forests, to defend against the invasion of beasts and insects, to maintain the balance of water and salt, etc.

Since the landing location of the manned spacecraft is difficult to control, especially the large spread of landing points during emergency return, this creates difficulties in the rescue of astronauts, not to mention accidents and completely leaving the predetermined landing area.

Therefore, the manned spacecraft will be equipped with personal rescue organisms for astronauts to seek help and survive during landing and waiting for rescue.

There are rescue contact items in personal rescue organisms so that astronauts can use them to contact rescue personnel as soon as possible. These items include radio communications and positioning devices, signal guns, fireworks tubes, seawater stains, flashlights, reflectors, fire-induced items, whistle flutes, cold protection and sunshade items, etc.

When the spacecraft returns to land in a cold zone or splashes into the water, astronauts wear cold-proof clothing or anti-absorbing suits to wait for rescue to prevent large-scale loss of body heat in a short period of time and prolong survival time.

When the astronauts return and splash into the water, there are floating devices, such as life rafts or portable floating devices, to support the human body to float on the water surface, and to wait for salvage and rescue.

Commonly used portable floating devices include carbon dioxide gas cylinders, floats, air blowers and other accessories.

When the astronaut splashes into the water, pull the inflatable rope, the striker pierces the sealing film of the gas cylinder, and the carbon dioxide gas fills the inside of the floating bag, and the floating bag inflates and expands.

Of course, you can also use the mouth to inflate the float through the inflatable tube, which will make the situation very sour.

Lifesaving food, drinking water and first aid kits are also very important personal biological rescue items. It is very important for landing in high-temperature areas to ensure that astronauts have a certain amount of drinking water.

Other personal survival items include pistols, shark repellents, fishing gear, filters, compass, self-defense knives, wire saws, dry fuel, heaters, windproof matches, etc.

These are originally necessary training subjects, but Tang Chao didn't ask them to do the training. The theme this time is still "experience" and "test", so training is not important, and the real warriors are all directly on!

Of course, it must be carried out in the virtual world. After all, the real world is prone to death. An astronaut is worth a thousand gold and cannot be messed up.

Let the company's senior management experience the reality of the virtual world, so they will not let them die in the virtual world. So don't look at the chirping in the sky, all the return capsules eventually landed on the ground "safely".

And the distance between everyone will not exceed one kilometer.

In other words, the snow, forests, seas, deserts, grasslands, mountains and other environments they saw before were all within one kilometer, and this thing can only be completed in the virtual world.

However, even if they all landed, this stimulation was unprecedented, and it was more exciting than bungee jumping.

Fortunately, they were not far away, and there were radio communications, positioning devices and signal guns in the survival equipment, which quickly gathered people together.

When they gathered together, they passed through their respective environments. After personal experience, they also found a lot of "unreal" evidence.

The evidence points out that this is a virtual world, not a real world, and they are more like they are traveling into a certain game world.

Modeling technology is more advanced, and the world is more realistic, but it is always limited by hardware.

For example, when they step on the grass and beach, they will feel their feet weak, but in fact it is not the feedback given by the ground, but the "feedback" brought by their feet.

As for current computer technology, every grain of sand on the beach can also be done in a scene where each grain of sand is a separate individual, but the physical collision between them takes up a large amount of computing resources. One hundred thousand people and one million people can be online at the same time. Only a few hundred people can be online at the same time.

So Tang Chao took a clue. The sand is still the same sand. From a distance, it looks clear and distinctive, and you can even reach out and grab a handful of sand.

But in fact, the entire sand is integrated and extremely sturdy. Only specific places or places that interact with hands and feet will adopt a more realistic physical state.
Chapter completed!
