As we all know, the cost of rocket fuel is very high, and China's raw material reserves are not superior. Therefore, in the development of aerospace technology, China has been somewhat restricted in the past few decades.

In fact, just like the reason why cars burn gasoline, low crude oil reserves will inevitably lead to high gasoline prices. Otherwise, many people in China say that they can afford to buy a car now, but they can't afford to refuel.

In order to overcome the shortfall of crude oil, China has been actively developing new energy technology, and it is said that in the next few years, perhaps China can replace gasoline with electric energy and become a new generation of power for automobiles.

The wisdom of the Chinese has led the world thousands of years ago, especially creativity. At present, many existing technologies in the world are derived from the inventions of Chinese history.

This is the case with the "Compass" series of satellites and the "Compass" series of spacecraft, which have completely broken the shackles of traditional science and technology and blazed a new trail, which can be said to be a step forward in the world's aerospace technology across the era.

The working principle is also very simple, the biggest obstacle to entering space is gravity, and the compass satellite is the opposite, by creating and radiating a special magnetic field, between space and the earth, to establish a relatively gravity-free channel. The compass spacecraft passed through this passage through the atmosphere and entered space.

Instructor Sun explained the whole process in detail. First set the flight trajectory, and the Compass One will take off through its own flying device, which is the role of those fan blades. When reaching a certain altitude, the compass orbiting satellite will open a gravity reduction channel, and then the compass spacecraft will use its own flight device and propulsion device to rush out of the earth in the shortest time.

One of the issues that needs to be overcome is speed. When the weight reduction channel is opened, the Compass One will reach a very fast speed, so fast that we can't imagine it. Because the opening time of the gravity-free channel will be very short, only a dozen seconds.

The first cosmic velocity of the rocket is 7.9 km/s, which can resist the gravitational pull of the Earth. It then accelerates to a second cosmic velocity of 11.9 km/s to resist the sun's gravitational pull. Moreover, they are all multi-stage rockets nowadays, which must be constantly disassembled during flight to reduce their own weight and increase speed.

Although the Compass avoided these problems, it had very high speed requirements, and the data budget showed that at its highest speed, it would reach 3,500 m/s, that is, a speed of 210 kilometers per hour, which is more than ten times the speed of sound.

I heard Instructor Sun always say that all the data came from the budget, so I asked him in surprise, could it be that the Compass One has not yet made an official flight?

Instructor Sun and the other instructors looked at each other for a moment and shook their heads slowly at me.

Shen Hao asked in surprise, "What do you mean?" Are we the first guinea pigs? ”

Instructor Sun hurriedly explained to us: "You don't have to worry about safety, although we haven't carried out real flights yet, we have carried out countless simulated flights, and there will be no problem at all." ”

Qixing said at this time: "But such a fast speed completely exceeds the limit of what the human body can bear, how did we solve this problem?" ”

Instructor Sun released the anatomical diagram of the main cabin of Luopan No. 1 and said to us: "You see, the main cabin is a three-layer protection design, especially the innermost third layer, which is an anti-high-speed decompression device. And there is also a dormant protection cabin in the main cabin, which allows us to spend this most difficult time unconsciously. ”

I exclaimed, "We are in a dormant state, can we say that Compass One is completely unmanned and flies into outer space on its own?" ”

Instructor Sun replied, "That's right! On departure, we all go into a hibernation protection pod, and when the pod is sealed, it fills with water, which means that we go into a floating state underwater. At the same time, with the use of drugs, our nerves will also enter a deep dormant state, so that our five senses will be completely unaware of the outside world for a certain period of time. In this way, both physically and psychologically, it effectively eliminates the harm caused by high speed. ”

It's a peculiar way, but I don't know how effective it is. Although Instructor Sun has repeatedly said that this method has been carefully calculated and there will be no problems, after all, it has not been used in practice, and I still have no bottom in my heart.

The ten-day assault training is over in a blink of an eye, and the skills and knowledge that we are required to master are poured into our minds like swallowing dates. Since the four instructors joined the joint operation team, we have known that compared with others, professionalism is simply heaven and earth.

But fortunately, with them on board, a lot of professional work is left to them, and our D.R.T members are more cooperative.

The day of departure is set for the eleventh morning of our arrival at this underground base. I'm kind of curious about why such a secret operation was carried out during the day. Instructor Zhao explained to me in a tricky way that the day is the time when we are least likely to be discovered.

This operation was taken seriously by the entire base, and many of the fighters from the base were waiting at the launch pad to see us off before we set off. This is not only a dangerous rescue operation, but also the first manned flight of Luopan One, which is of great significance.

The nine of us first changed into space suits, and then led by the guards, to an underground passage leading to the launch pad. There, we were received by the leadership of the base, the head of which was a spirited old man in his sixties. He didn't wear a military uniform, and he couldn't see the rank, but judging from his spirit, he was definitely a general.

He shook hands with us one by one and wished us all the best of luck and a safe return home.

After bidding farewell to the chief, we marched along the passage, and the armed men on either side saluted us at the same time, paying the highest respect.

At this moment, my blood boiled, and I returned a military salute to those soldiers, which was the first time I had saluted so solemnly again since I left the army.

Coming out of the passage, several spotlights hit us, followed by earth-shattering applause. We looked up and saw that the lookout platform above the launch channel was densely packed with people who had come to see us off.

The four instructors and I saluted the troops, while the others bowed deeply.

The guards escorted us to the door of the Compass One cabin and left, and after waving goodbye to the crowd behind us again, we climbed the ladder to enter the Compass One.

Entering the main cabin door, we were first physically scanned, then entered the secondary hatch, disinfected, and sprayed us with liquid and then gas before we were allowed to enter the main cabin.

The first cabin of the main cabin is where we put on the "Zhengtian" flight suit. A row of spacesuit storage cabinets, the lights in the cabinets come on after we enter, and above each cabinet are marked a number representing our symbol.

I found that there are a total of ten cabinets stored here, in addition to 1~9, there is also a No. 0 cabinet, which also has a Zhengtian spacesuit. Instructor Li told me that this was a backup spacesuit, a substitute to prevent the failure of the spacesuit.

Looking at the ten cabinets, I couldn't help but think that there were exactly nine spacesuits in addition to the reserves. Is it because there are exactly nine people in our group, or is it because we can only take nine people in the first place?

Following our numbers, we changed into our own spacesuits, and after confirming that the system was working properly, we moved on to the next cabin. This cabin is circular, there are eight cylindrical independent cabins in each row on the left and right, a total of sixteen, depending on the size of only one person, Instructor Sun said that this is the dormant protection cabin we will enter when we set off.

At this point, I got a call from the console in my headset saying that if we were ready, we could go into the hibernation pod.

The control center is able to locate our signals and confirm the position of each of us in the Compass One. At the same time, we all have a pocket-sized camera on our left shoulder that transmits the captured video to the control center. The independent system, including our spacesuit, is also connected to the control center, and even our body data is under the supervision of the control center.

The four instructors let us enter the hibernation pod first, and I chose the left side, so the instructors opened the doors of the five hibernation pods for us.

Seeing nothing special inside, I walked in first, and then the hatch closed. Instructor Qian patted the glass of the hatch in front of me and said, "Sleep well, when you wake up, we will have reached outer space." After saying that, he waved at me, and walked into the hibernation pod opposite with the other three instructors.

I took the opportunity to greet the rest of the D.R.T. team and ask them how they were feeling.

Shen Hao was the first to answer me and said that I didn't feel anything other than being nervous, and I smiled and said that when I fell asleep after a while, I wouldn't be nervous. Feng Jiutian said that she didn't like this jar, which made her feel depressed. Qixing advised her to take more deep breaths and try not to think about the feeling of depression, it would be much better. Shen Hao also shouted that he knew that he was so nervous, so he should drink more wine before coming in.

Maybe everyone is a little apprehensive in their hearts, so there are a lot of words, and you and I are talking lively. But I just didn't hear An Beimo speak for a long time, so I asked, "Goddess, how are you?" Why don't you speak? ”

Listening to my question, the others also noticed that An Beimo had not made a sound, and immediately stopped talking nonsense.

"Say what?" An Beimo's indifferent voice came: "I'm already starting to get sleepy!" ”

I was stunned, everyone was nervous, excited, and uneasy at this time, but I didn't expect An Beimo to say that she was sleepy. After being quiet for more than ten seconds, suddenly An Beimo "giggled" and laughed, and then the others also laughed. I was so impressed by everyone's laughter that I laughed along.

I don't know what's funny, I just want to laugh from the bottom of my heart, from the beginning, gradually turn to unbridled laughter.
