As the spacecraft accelerated, they soon came to the vicinity of the asteroid and began to slow down until the speed of the spacecraft was the same as that of the asteroid. At this time, the spacecraft no longer slowed down, but maintained the same speed as the asteroid.

When the speed of the spacecraft was the same as that of the asteroid, Wang Wei and the others began to prepare for the next step, which was to reduce the rotation force of the asteroid. After all, the speed of the spacecraft was the same as that of the asteroid. The difference between the two

The relative speed is zero, so as long as the asteroid stops rotating, they can easily capture the asteroid.

Although the relative speed between them and the asteroid has reached zero at this time, it is not easy to stop the asteroid from rotating. After all, this is in a universe without any leverage.

Rather than on the earth, if it were on the earth, it would be relatively difficult to stop an object of hundreds of tons from rotating. But it is different in the universe.

Fortunately, when designing this spacecraft, the designers had already considered that as a space research ship, their spacecraft would definitely carry out the mission of capturing asteroids in the future, so they still have the ability to make this spacecraft

The asteroid stopped spinning.

Of course, their spacecraft also has a variety of methods to stop the asteroid from rotating, such as using ultra-high-strength carbon fiber mesh, using more than powerful steel wires, and using unmanned robot engines.

Of course, the safest way is to use an unmanned robot engine. After all, the size and weight of this meteorite are within the range of the spacecraft. But in fact, for such a large asteroid, the only way they can take is

One way is to use unmanned intelligent thrusters.

Then Wanwan immediately ordered the launch of the unmanned intelligent thrusters. The size of the unmanned intelligent thrusters was not large. Each one was about three meters in length and about twenty centimeters in diameter.

However, although these unmanned intelligent thrusters are not large, the maximum thrust of each of them exceeds ten tons, reaching about thirteen tons. However, these unmanned intelligent thrusters themselves are not light, and their dead weight has also reached ten tons.

About tons. If it were on the earth, these unmanned intelligent thrusters would not be of much use. After all, if their own weight is removed, the thrust of these engines would only be three tons. But it is different in the universe. These unmanned propellers would not have much effect.

Intelligent thrusters can exert maximum efficiency.

Soon these unmanned intelligent thrusters arrived near the asteroid.

"Report! There is still about a kilometer of distance between the smart thruster and the asteroid. It is now slowing down and slowly approaching the asteroid. It is expected to meet the asteroid in thirty seconds."

The smart thruster is approaching the asteroid, the crew member responsible for assisting in controlling the unmanned smart thruster said.

As time passed, thirty seconds later, the probe finally approached the asteroid.

"We are still three meters away from the asteroid, ready to embed into the asteroid."

"Bang!..." The first unmanned intelligent thruster was successfully embedded into the asteroid and fixed itself instantly.

Then the second and third ones were also embedded in the asteroid instantly.

"Report! On the 3rd, 4th, and 6th, the unmanned intelligent thrusters failed to cut in. They are re-adjusting their orbits and preparing to embed again."

Wang Wei and others were not surprised by the failure of unmanned intelligent thrusters to be embedded in asteroids, because at the beginning of the design, according to the data, the use of unmanned intelligent thrusters to embed asteroids was not 100% successful, only about 5%.

It's just a 10% success rate. He would be surprised if it was 100% successful.

"The No. 3 unmanned intelligent thruster was successfully embedded!"

"Unmanned intelligent thrusters No. 4 and 6 failed to embed again and are returning."

Because Wang Wei and others knew that embedding unmanned intelligent thrusters into an asteroid would not go smoothly, so according to the data, only four unmanned intelligent thrusters were enough to stop the asteroid's rotation, but they still launched six

The purpose of Taiwan's unmanned intelligent thrusters is to take pictures of the failures of some unmanned intelligent thrusters when they are embedded in asteroids.

"Adjust the posture of the unmanned intelligent thruster and prepare to start!"

"The attitude adjustment is completed and ready to start the engine."

"start up....."

I saw four unmanned intelligent thrusters on the asteroid ejecting dazzling firelight instantly, and under the action of these four unmanned intelligent thrusters, the asteroid's rotation speed also began to slow down significantly.

"Report! The engine has been started. It is expected that the meteorite will stop rotating in 195 seconds, and the fuel of the four unmanned intelligent thrusters will also be exhausted."

Since the size of the unmanned smart thruster is limited, the fuel it can carry is also very limited, and it cannot carry a small nuclear reactor. One smart thruster can only work for a maximum of 200 seconds.

When human civilization develops nuclear fusion technology in the future and miniaturizes it, there will be no need to worry about working hours.

At the same time, the detectors and smart thrusters near the asteroid are transmitting the asteroid's operation data and the output thrust data of the unmanned smart thruster itself to the spacecraft all the time.

"The engine working time is 20 seconds, the asteroid revolution speed is 20 kilometers per second, and the rotation speed is 15 seconds per week. The output power of the No. 1 engine is 10.10 tons, the No. 2 engine is 10.11 tons, the No. 3 engine is 10.12 tons, and the No. 4 engine is 10.05 tons. Estimated working time

180 seconds.”

"The engine working time is 50 seconds, the asteroid's revolution speed..."

As the engine started working, everyone in the spacecraft stared silently at the virtual screen.

After all, this is the first time that the entire human civilization is responsible for an asteroid in the universe.

Although the maximum diameter of this asteroid is less than two meters and its weight is less than 200 tons, to the experts and scholars in the spacecraft, although this asteroid is small, it is already very precious.

Soon, the asteroid finally stopped rotating under the influence of unmanned intelligent thrusters, and the spacecraft driven by Wang Wei and others began to approach the asteroid.

When the spacecraft flew close to the asteroid, a hatch on the side of the spacecraft was opened, and a huge manipulator stretched out from inside. At this time, the spacecraft gradually approached the asteroid. When the spacecraft and the asteroid

When the distance between asteroids is only about five meters, they no longer get closer.
