After the three Xuanwu-class spaceships merged, it was about ten minutes later.

They slowly separated again, but at this time, there was an extra net between the three Xuanwu-class ships.

The net is an equilateral triangle with a side length of 300 meters, and the material of the net is made of high-strength carbon nanotubes, which even astronomical telescopes cannot detect in the darkness of outer space.

"The net is open."

"The fishing plan is ready." Zeng Baojiang waved his fist and shouted.

"Yes."

A group of remote control department staff began to stare nervously at the holographic computer, and their task was to assist the artificial intelligence and correct the mistake in time.

Wang Tu looked at his watch again, and it was December 10, 2019, at 15:22 p.m.

If their fishing plan fails, then the planetary railgun plans to strike first at 17:34.

The other side.

Pakistan-China base.

Academician Ma, Zhao Hongxing and others are also watching the fishing plan, and the success or failure of the fishing plan will determine whether the planetary railgun at the Bazhong base will be activated.

"Old horse, get the planetary railgun ready." Zhao Hongxing looked at the time and ordered.

"Okay." Academician Ma nodded, then turned to his assistant and ordered, "Let the planetary railguns be in place." ”

"Yes." The assistant hurriedly went to inform the operation department of the planetary railgun.

"Old horse, will your fishing plan succeed?" Zhao Hongxing looked at the holographic star map and asked.

Academician Ma tensed his spirit, thought for a while and replied: "Five-five, communication delay is a fatal problem, which may cause a situation where cooperation is not in place. ”

"......" Although Zhao Hongxing was very calm on the surface, his hands holding the railing tightly, it could be seen that he was nervous in his heart, but now no one paid attention to his hands, and everyone was staring at the holographic star map.

As Academician Ma said, even Dongtang didn't know that the Galaxy Consortium had artificial intelligence, so they were nervous about the problem of communication delay.

Only Huang Haojie is relatively calm, because under the control of the "star" and the assistance of the ground remote control department, the success rate of the fishing plan is very high.

In fact, the fishing plan was prepared by Huang Haojie for space mining, and after a long period of refinement by Zhong and him, the asteroid capture technology has been relatively perfect.

If the WX asteroid is successfully captured, it is equivalent to obtaining 4.2~450 million tons of iron-nickel ore, and if it fails, the WX asteroid will be destroyed.

Next to the WX asteroid, in a parallel orbit less than five kilometers away from it, three Xuanwu-class spacecraft that have opened their nets are slowly changing their positions with the help of auxiliary engines.

Why start a fishing program on a parallel orbit with a companion? Instead of casting a net to catch fish when they meet head-on?

This is mainly due to the engine power and relative speed.

The engine power of the Xuanwu-class spacecraft is not enough to fight the WX asteroid head-on, after all, the speed of both sides is very fast, and the relative speed is even more terrifying.

Thinking that the little power of the Xuanwu class, if you want to work a WX asteroid with a speed of 15.59 kilometers per second and a mass of 4.2~450 million tons, even a hundred Xuanwu-class ships can't do it.

The consequence of the hard work is that the Xuanwu-class spacecraft will be wiped out, and the WX asteroid will continue to kill the blue star after the skin is broken.

Therefore, the Space Development Committee chose to fly with the boat, slowly approaching the WX asteroid in a parallel orbit, and using the method of pushing the boat along the river.

Just like driving, a car traveling at high speed, if it suddenly makes a sharp turn, it will either derail or overturn; If you change direction slowly, you can make a safe U-turn.

Under the operation of "Star", the position of the Xuanwu-class 004 spacecraft slowly moved to the right rear direction of the WX asteroid; The Xuanwu-class 002 spacecraft went up to the right; The Xuanwu-class 006 spacecraft is headed down to the right and forward.

The orbits of the two sides slowly changed from the original parallel orbits to a small angle crossing track, but this angle angle is very small, only about 2 degrees.

The three Xuanwu-class spacecraft pulled the carbon nano network network and slowly wrapped around the WX asteroid, this process proceeded very slowly, and the speed of the three spacecraft reached 15.62 kilometers per second under the adjustment of the "star", which is only a little faster than the speed of the WX asteroid.

As the minutes and seconds passed, the ground control center and the world's aerospace or astronomical institutions all broke out in a cold sweat.

At 15:37, the three Xuanwu-class spacecraft finally wrapped the carbon nano-pipe network on the WX asteroid, because the angle between the two flight orbits is very small, and the flight speed is very close, so the reaction force of the WX asteroid to the three Xuanwu-class is still within the tolerance range of the spacecraft.

Syllable! Wang Tu slapped the railing heavily: "Don't let your guard down, we have reached the most critical time." ”

In the Kaohsiung control center, the people in the remote control department did not dare to come out, and they all stared at the holographic computer, for fear that a mistake would ruin their previous efforts.

[Drop!] Abnormal! Abnormal! The remote control system suddenly became alarmed, and everyone's hearts tightened in an instant.

"Let's see what's going on?" Zeng Baojiang shouted hurriedly.

The staff is also fully engaged at this moment.

"It's the mass anomaly of the WX asteroid, which is heavier than we predicted, reaching about 490 million tons."

Zeng Baojiang frowned, and immediately ordered: "It is 40 million tons larger than we predicted, start the auxiliary engine immediately, and increase the power of the main engine." ”

"Yes."

In the face of such an unexpected situation, the "Star" did not know how to solve it, and could only follow the established procedures, but fortunately, the ground control center corrected the engine data in time, otherwise it would be a big trouble.

Of course, there is no shortage of trouble now, and the ground control center hurriedly modified this data and asked the supercomputing center to recalculate it, because the quality has changed so much, and everything else is also changing.

All the supercomputing power of Dongtang and the Galaxy Consortium was fully opened, and the results came out after adjusting the data in less than three minutes.

"One good news and one bad news." Zeng Baojiang said helplessly.

"Say it!" Wang Tu stared at the holographic star map expressionlessly and said.

"The good news is that the WX asteroid is still within the controllable range, and the bad news is that the cross orbit of the WX asteroid and the blue star has changed from the previous 19,000 kilometers to between 1000~2000 kilometers." Zeng Baojiang marked the latest orbit of the WX asteroid on the holographic star map.

"At least it's manageable." Wang Tu secretly breathed a sigh of relief.

"In addition, due to the mass of the WX asteroid, the time that the spacecraft can support with fuel may be reduced by about 12% compared with the projection." Zeng Baojiang continued.

"Start the spare Qinglong-class No. 002 and No. 004 and prepare for refueling." Wang Tu immediately commanded.

"But......" Zeng Baojiang just wanted to say something.

"Nothing, do it immediately." Wang Tu said categorically.

"Yes!"

At this time, the flight trajectory of the WX asteroid was slowly changing, and the three Xuanwu-class spacecraft were desperately correcting their direction.

Starting the engine for a long time made the nozzle a little red, but fortunately, the Space Development Committee found the problem of fatigue deformation of the nozzle and sprayed a layer of mixed gel on the engine nozzle, which can withstand high temperatures of 14,000 degrees Celsius.

If it was the previous nozzle, such a high-intensity use of the engine would definitely have a problem.
