Super technology leader

"Alright, next project, return to Earth."

Tang Chao pointed to a row of spacecraft docking ports.

"Yeah! Finally, we're going to fly a spaceship!"

"I learned a lot just now. Watch me make a perfect landing for you!"

"Haha, I feel like I'll be the first to land!"

"I'm not just going to land, I'm going to land a bullseye!"

"Keep dreaming. I reckon I'll only manage a nine-ring."

Watching the chattering crowd, Teacher Du strictly followed Tang Chao's testing process and began assisting.

"Alright, listen to the key points I'm going to explain. Three people per return capsule…"

As he watched the group being arranged into the return capsules, Tang Chao revealed a smile.

"They still want a smooth landing, or even a bullseye landing? Dream on. This landing process is for demonstrating accidents."

The previous space experience and ground training equipment experience were like walking through a door, a direct scene change. This time, they'll experience atmospheric re-entry.

After so much training and so many simulated experiences, they have to 'really' fly once.

Astronauts need to operate various instruments and equipment during missions, but there are countless devices in spacecraft, especially in early spacecraft where the control interface was full of buttons.

If an astronaut makes even a small mistake during operation, especially the pilot, it could lead to the destruction of the aircraft and loss of life.

Therefore, before astronauts pilot real space equipment into space, they must train on various simulation devices on the ground so that they can become familiar with operating procedures and adapt to different environments.

But speaking of "different environments," spacecraft simulation equipment and the real spacecraft environment are different, with an insurmountable gap between them.

It's not just a gap; there are various dangers that can arise at any time. In the history of human spaceflight, many astronauts have died in simulation capsules.

Du Kangsheng had used similar simulation capsules before. Although he had memorized the operating procedures and button positions perfectly, the feeling was completely different when he entered the cockpit of the orbital shuttle, especially after the shuttle entered space.

This time, entering the virtual space for the experience, he tried both the ground simulation capsule and the "space simulation capsule." Comparing the two, wow, they were worlds apart.

Compared to the ground simulation equipment's "advertisement" of providing astronauts with various sensations such as movement, vision, hearing, and operating load, making them feel like they are really piloting a space spacecraft, the virtual space simulation capsule is the real deal.

It directly simulates the entire process, such as simulating the spacecraft's takeoff, orbit insertion, attitude control, space docking, space maintenance, and extravehicular activities. The whole process made him, a real astronaut, think he was flying a real spacecraft.

The training effect was quite "explosive."

Well, the spacecraft carrying the group exploded after entering the atmosphere.

Fortunately, the explosion wasn't large; it only caused the spacecraft to deviate from the landing trajectory, and the deceleration parachute also malfunctioned.

"Ahhh, why is my return capsule spinning? Where are we going to land?"

"I-I don't know. All I know is I'm going to be sick, ugh…"

"Damn it, don't you dare throw up!"

"Warning, warning, descent speed too fast!"

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

"I'm over the ocean. I don't know where I am either!"

"It's a vast expanse of white. It must be snow! Damn it!"

"I'm here… screech, communication lost!"

………………

Manned spacecraft may land in various complex terrains, climates, and other harsh survival environments during emergency returns, such as frigid zones, deserts, mountains, forests, and seas. Therefore, astronauts must be trained in the survival knowledge and skills of these areas to familiarize themselves with the climate changes, terrain, sea conditions, and flora and fauna of these areas, and master the basic survival skills.

For example, maintaining the body's thermal balance in cold regions, defending against the invasion of beasts and insects in primeval forests, and maintaining water and salt balance in the desert.

Because the landing point of manned spacecraft is difficult to control, especially during emergency returns, the dispersion of the landing point is large, which makes it difficult to rescue astronauts, let alone when accidents occur that completely deviate from the planned landing area.

Therefore, manned spacecraft are equipped with personal survival items for astronauts to use for distress calls and survival while waiting for rescue after landing.

Personal survival items include distress communication items so that astronauts can use them to contact rescuers as soon as possible. These items include radio communication and positioning devices, signal guns, flares, sea water dyes, flashlights, reflectors, fire starters, whistles, cold and sun protection items, etc.

When the spacecraft returns and lands in cold areas or splashes into the water, astronauts wear cold-proof clothing or immersion suits to wait for rescue, preventing a large loss of body heat in a short time and prolonging survival time.

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

The latest novels are first published on 69shu.com!

Commonly used portable flotation devices include carbon dioxide cylinders, floats, inflation tubes, and other accessories.

When the astronaut splashes into the water, pull the inflation cord, the firing pin punctures the gas cylinder sealing film, and carbon dioxide gas fills the inside of the float, inflating the float.

Of course, you can also use your mouth to inflate the float through the inflation tube, which is very uncomfortable.

Emergency food and drinking water and first aid kits are also very important personal survival items. For landing in high-temperature areas, ensuring that astronauts have a certain amount of drinking water is very important.

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

These were originally mandatory training subjects, but Tang Chao didn't intend to train them. The theme this time was still "experience" and "testing," so training wasn't important. Real warriors go straight in!

Of course, it had to be done in the virtual world, because the real world is easy to die in. An astronaut is worth a thousand gold, so you can't mess around.

To let the company's senior management experience the realism of the virtual world, naturally, they wouldn't let them die in the virtual world. So, despite the screaming in the sky, all the return capsules "safely" landed on the ground.

And the distance between everyone would not exceed one kilometer.

That is to say, the snow, forests, seas, deserts, grasslands, mountains, and other environments they saw before were all within one kilometer. This could only be done in the virtual world.

But even if they all landed, the excitement was unprecedented, more exciting than bungee jumping and skydiving.

Fortunately, they were not far apart, and the survival equipment included radio communication, positioning devices, and signal guns, so they quickly gathered everyone together.

While gathering together, they passed through their respective environments, and through personal experience, they also discovered a lot of "unreal" evidence.

Those evidences indicated that this was a virtual world, not a real world. They were more like they had traveled into a game world.

The modeling technology was more advanced, and the world was more realistic, but it was always limited by hardware.

For example, they would feel their feet soften when they stepped on grass and beaches, but in reality, that was not the feedback from the ground, but the "feedback" from their own feet.

With current computer technology, scenes where every grain of sand on the beach is a separate individual can be created, but the physical collision between them would take up a lot of computing resources, and a data center with 100,000 or 1 million people online simultaneously would only allow a few hundred or a few thousand people to be online simultaneously.

So Tang Chao cheated a bit. The sandy beach was still the sandy beach. From a distance, it looked granular, and you could even reach out and grab a handful of sand.

But in reality, the entire sandy beach was one piece, and it was extremely solid. Only specific places or places that interact with hands and feet would use a more realistic physical state.
