The high cost of space launches, mainly in rocket launches.

A year ago, North American SpaceX successfully launched and culled the Falcon 9 rocket, the first time in human history that a rocket was launched into space and then returned to Earth. The president of its company said that if the rocket can be reused like an airplane, then the cost of going into space can be reduced by a hundred times!

SpaceX's Falcon 9, the cost is 60 million US dollars, but the fuel of the rocket is only 200,000 US dollars, if it can be repeatedly launched, then plus the repair cost after the launch is about 500,000 US dollars, then to make a Falcon 9, each subsequent launch, the cost is only 700,000 US dollars, it is indeed a large amount of money left, for aerospace, is a very exciting news.

In China, the space agency is also studying the reuse of space rockets, but progress is not ideal.

After the scientific analysis of the national aerospace team, if Chen Mingxuan's floating power system of Caiyun Company can be launched into space, according to the attributes of the float, the possibility of returning to land and reusing is as high as 99.9%!

Therefore, the state and the China National Space Administration have expressed a strong interest in Chen Mingxuan's floating power system, and they are also very concerned.

Today is a month after Hulu-1 entered space, and it is also today that Chen Mingxuan will prepare for a return landing on Hulu-1.

Thanks to the strong support of the Northwest Space Field and the Space Bureau, Chen Mingxuan directly asked the space site to manufacture a miniature signal converter, referred to as the array converter. When Yang Ke received the drawings, he asked what it was, and was prevaricated by Chen Mingxuan.

On this day, Chen Mingxuan took his notebook directly into the main control hall of the Northwest Space Field, and used the miniature array converter to connect to the C01 control server to indirectly control Hulu No. 1.

"OK, we have reduced the speed of Hulu 1 to 5,000 kilometers per hour, and now it is over the Eastern Magic Capital, we need it to draw a parabola from the Magic Capital into the northwest, and then reach Suzhou, the Northwest Space Field."

On such an important day, Guo Ming was also there, because he also wanted to know at the first moment whether the floating power system had the ability to return to reuse.

"How long will it take?" he asked. ”

"We went from an altitude orbit of 9.34 kilometers per second, more than 600 kilometers per second, and now it took half an hour to 5,000 kilometers per hour, because there is almost no air in space. But now, we came from an altitude of 120 kilometers above the magic capital, and it took about a hundred minutes. ”

Yang Ke said: "Your speed is much slower than the speed of the recovery capsule, generally returning at an altitude of 120 kilometers, and the speed is also seven kilometers per second, that is, more than 20,000 kilometers per hour." ”

"The return curve of Hulu 1 is not really a parabola. It will enter the northwest at an altitude of 95 km, at which point the horizontal speed will drop to 100 km/h, and then it will descend almost vertically. ”

Guo Ming was puzzled: "Vertical descent? ”

Chen Mingxuan nodded and said: "That's right, the floating power system, the most important thing is the levitation, if we adjust the speed and position in outer space where there is almost no air, and then land, this is the fastest and safest." ”

Guo Ming said: "You are anti-gravity technology? ”

Chen Mingxuan was stunned for a moment and shook his head: "No, it's not." This is a repulsion technique, which uses jade to excite the magnetic field generated by the energy oscillation, which repels the earth's magnetic field, and then immortalizes an effect similar to anti-gravity. ”

Yang Ke and several team leaders next to him listened with their ears pricked up, and Guo Ming asked, "Can you tell me the principle?" ”

"Well, didn't you already tell me the principle?"

Guo Ming touched his head and said, "You are too vague." Now that we have more than an hour to spare, you can give us some knowledge. ”

Chen Mingxuan shook his head: "I have already told the principle of the effect, and you also have the manufacturing drawings of the floating power system." ”

Yang Ke complained: "When Lao Maozi split up, we got some cutting-edge technology, but we did it with bad results, but it is also very useful, you this, we make it, and you can start it." ”

Chen Mingxuan will not be embarrassed: "So what, this is my private technology, without private locks, how can I rest assured that it will be made by you." ”

Guo Mingzheng was about to speak, but Chen Mingxuan raised his hand to stop him: "Hey, don't say it, I won't give you the method to start, let's cooperate." Rest assured, I will not work with foreign structures and organizations. Think about it, we have a huge market in China, I can make a lot of money if I want money, I want resources, with a floating power system, even if I can't build an airport, send a spaceship to outer space, capture a small meteorite or something, I'm afraid that there will be no resources? ”

Guo Ming smiled and said: "You think beautifully, outer space is so empty, you think that the little meteorite is so easy to track and capture." ”

After more than an hour, Hulu 1 has reached the northwest and has descended to an altitude of seventy kilometers.

Chen Mingxuan adjusted the internal concentrating array to the maximum extent of heat absorption, and then told the descent that the huge friction caused the appearance of the hoist No. 1 to produce high temperatures, but under the absorption of the concentrating array, the floating power system basically maintained the temperature at about 20 degrees.

At this moment, a large amount of data needs to be calculated and processed, but connected to the C01 control server of Jiuquan Supercomputer, the entire descent process is perfectly controlled without any amount of calculation.

The altitude is reduced to 20 kilometers and the speed is at 1000 kilometers per hour!

The altitude is reduced to 15 kilometers and the speed is 900 kilometers per hour!

The altitude is reduced to 10 kilometers and the speed is 800 kilometers per hour!

The altitude is reduced to 80 kilometers and the speed is 750 kilometers per hour!

……

The altitude drops to 7000 meters and the speed is 100 kilometers per hour!

The altitude is reduced to 1000 meters and the speed is 10 kilometers per hour!

The height is reduced to 100 meters and the speed is 10 meters per second!

All the processes were reflected in Chen Mingxuan's notebook, and also on the huge screen in the entire main control hall, because they were also connected to Chen Mingxuan's control system.

Chen Mingxuan picked up the computer, grabbed the miniature array converter, and ran directly out of the hall and ran to the yellow earth outside!

A group of people waited, and they also came out.

Now, a large black dot has been seen with the naked eye falling from the sky, and when it falls ten meters from the ground, the entire Hulu No. 1 has hovered there.

Guo Ming and Yang Ke and other aerospace workers, like looking at a beautiful art treasure, looked up at the entire rough steel frame of the Hulu No. 1!

To be honest, although Hulu 1 went through high-speed friction on the return trip, there was no high temperature and scorching, so there was basically no damage to the surface except for the aging of multiple radiation due to the harsh environment of outer space.

Chen Mingxuan pressed on the notebook, and the entire Hulu No. 1 began to descend slowly, and then gently fell to the ground.

He saw a staff member next to him holding a pair of work gloves in his hand, closed his notebook directly, handed it to the person on the side, and then took the staff gloves, and went directly into battle to start opening the alloy cabin carried by Hulu No. 1.

The detector outside the Hulu No. 1 showed that there was no problem on the computer control system, while the inside of the alloy cabin was ...... When Chen Mingxuan opened it, he said in his heart that there would definitely be no problem!

Opening the alloy cabin, Chen Mingxuan glanced inside, and then left.

"Director Guo, Section Chief Yang, let your people help check if there is a problem with the electronic system. There is definitely no problem with the floating power system, and I know this when I control the return landing. ”

Yang Ke said: "Don't you need to open it and take a look?" I mean, the floating power system. ”

Chen Mingxuan suddenly remembered something and turned to Guo Ming: "I remembered, Director Guo." ”

"What do you remember?"

"Director Guo, if I'm not mistaken, the Energy Research Institute in Yanjing has the equipment to detect the internal energy of jade, right?"

Guo Ming smiled: "You want this technology, don't you?" ”

Chen Mingxuan said: "I do want to. ”

Guo Ming said: "That's not cheap. ”

Chen Mingxuan was stunned for a moment, he didn't know what he meant, and said immediately: "Director Guo, don't think about pit me, just think, can you help me pull a line, you see how much it costs me to buy a set of equipment." ”

Guo Ming said: "Dong Chen, I can't say how much the price is." ”

"I've checked, there is relevant technology in North America, and a piece of equipment is about 10 million dollars."

"Ahem......" Guo Ming didn't expect Chen Mingxuan to do his homework.

Chen Mingxuan said: "Director Guo, Section Chief Yang, you will arrange the follow-up testing." In this way, we will start a new round of testing in five days, and Section Chief Yang can arrange a measurement of 500 tons, and we will also use 600 kilometers of high-altitude track as the test altitude. ”

That night, the entire Northwest Space Field entered the celebration mode, and the Gobi Desert was full of joy.

However, Chen Mingxuan is still working on his own project on his C01......
