In the Dumbo spacecraft, the ten crew members are busy with their own affairs, and some are in contact with their families on this side of the earth, but although the speed of electromagnetic waves is comparable to the speed of light, the distance between them and the region at this time has exceeded more than 1 astronomical unit, and a one-way journey at the speed of light also needs to be delayed for nearly 8 seconds, and a delay for a round trip takes more than 10 seconds.

The information received now is the information sent from the earth more than ten seconds ago, and the traditional electromagnetic communication technology is not much of a problem on the earth, but once it enters the interstellar universe, it is increasingly unable to meet the needs of development, and this is only in a very small area of the solar system.

Despite the long delay in the call, the crew was still happy to keep in touch with their friends and relatives on this side of the earth, because the long journey was so boring, the scenery outside the spaceship seemed to be eternal, and the stars in the dark starry sky were dotted with stars, and the source of the light had already been lost.

Contacting relatives and friends on this side of the earth, and some sleeping quietly and reading books here in the plant area, the anxiety and irritability in the heart are getting more and more serious after a long interstellar journey, and only by taking a good rest here in the plant area can the negative emotions in the heart be alleviated.

There are also people who continue to work out in the gym, and everyone knows very well that if they still want to live a healthy life after returning to the earth, the time and intensity of this fitness cannot be discounted at all, not for others, but for themselves.

In mid-April 2022, the spacecraft flew through the orbit of Mars, but at this time Mars is very far away, otherwise you can really take a good look at the appearance of Mars, after crossing the orbit of Mars, the distance from the asteroid belt is already very close.

"Team Luo, we're starting to need to slow down the spaceship now!"

Tang Boyuan and Dong Zhifei naturally passed the latest calculation results to Luo Xiaoyao.

"What do you say on this side of the Earth?"

Luo Xiaoyao nodded, according to the plan, he was about to start slowing down, but he still had to listen to the opinion of the command center on this side of the earth.

"That's what this side of the planet means, starting to slow down."

Tang Boyuan nodded, conveying the meaning of the earth, the supercomputer has simulated all the possibilities.

"Start slowing down!"

Luo Xiaoyao nodded and began to order.

The huge Dumbo spacecraft is equipped with a reverse plasma engine in the front and rear to slow down, and at this point the two engines start to work, spraying a reverse tail flame, and the speed of the spacecraft begins to slowly decrease.

"Turn on X-ray inspection, γ-ray inspection, β-ray inspection, infrared radiation detection, magnetic field detection!"

"Turn on the 3D stereo radar and produce 3D stereo images!"

"Turn on the weapon system and be ready at all times."

"Launch of unmanned exploration satellites."

One order after another was issued from Luo Xiaoyao, the asteroid belt that was about to arrive was not a warm and empty void, and it could be hit by an asteroid at any time, so the detection radar had to be turned on, and it was not turned on in order to save energy in the front.

At the same time, the weapon system is also on standby, the spaceship flies in the cosmic void, generally flying in a straight line, if you want to avoid the impact of meteorites, asteroids and change the flight trajectory, the energy consumed will be very amazing, especially when the mass of the spacecraft is larger, the greater the energy consumed.

Therefore, under normal circumstances, the method of destroying meteorites and asteroids in front of them will be used, and weapons will be used to destroy them, and the Dumbo spaceship carries two weapons, rail guns and missiles, and there is definitely no problem in dealing with ordinary asteroids.

As for the release of unmanned exploration satellites, it is to grasp the situation of a large range of void as much as possible, these exploration satellites are very cheap, one-time products, the number is relatively large, and it is also the situation of Fuyun Group in order to grasp more of the solar system, so it will continue to release some unmanned exploration satellites along the way.

The crew of the spacecraft also began to get busy, starting to overhaul the spacecraft and equipment, conducting emergency drills, etc., and at the same time, they were also full of anticipation for the upcoming asteroid belt.

As the days passed, the spacecraft slowed down and got closer to the asteroid belt.

"Didi, discover an asteroid."

At the beginning of June, the detection radar on the Dumbo spacecraft finally discovered the first asteroid, and everyone on board began to get excited, and they finally arrived at the asteroid belt.

"This asteroid is 5,980 kilometers away from us, and according to the analysis of spectral images from exploration satellites, it is mainly made of 40% iron, 30% copper, and the rest is basically silicon."

"It has a diameter of more than 456 meters, an irregular shape as a whole, and a mass of more than 300 million tons, which is not our dish."

In Tang Boyuan's mind, the virtual machine directly transmitted the relevant information to his brain, and he analyzed the data and quickly came up with relevant information about the asteroid.

Calculating the mass, volume, and main elements of a celestial body is a task that almost everyone majoring in astronomy can easily do, but for ordinary people, it is completely confusing, and they do not know why they can calculate the mass of a star from a distance of thousands of kilometers.

"Keep going, continue to release probe satellites around!"

After Luo Xiaoyao got Tang Boyuan's report, he continued to give the order to advance.

The Dumbo spaceship continued to fly in the void, and the speed was already quite slow, only a dozen kilometers per second, and the detection satellites on the spacecraft were scattered in all directions like no money.

Although the asteroid belt is said to be an asteroid belt, there are countless asteroids, but they are distributed in such a vast area, when you really feel that the asteroid belt is very empty.

Three days had passed since the discovery of the first asteroid, and neither radar nor satellites had found a second asteroid, and the crowd was depressed until the fourth day.

"Didi, Didi, discovery of asteroids, discovery of asteroids."

The entire spaceship was awakened by the alarm sound of the system, and they hurriedly connected to the virtual machine one by one.

"Haha, we are almost in the center of the asteroid belt now, and in front of us is the edge position, and dozens of asteroids have been discovered at once."

The information of dozens of asteroids in his mind came to his mind, how far away from the spaceship, in that direction, etc., Luo Xiaoyao couldn't help but laugh happily.

"Xiao Tang, Xiao Dong, it's up to you next."

"Don't worry, I'll find the most suitable asteroid to bring back."

Dong Zhifei grinned and began to be half a person with Tang Boyuan, using the computer to start analyzing these asteroids, calculating their mass, volume, direction, distance, velocity, constituent elements, and so on.

"Buzz, buzz, alarm, alert, there is an asteroid whose trajectory is about to coincide with the spacecraft's flight trajectory, please deal with it immediately."

At this moment, the warning on the spacecraft was loud, and when everyone heard it, their faces became serious, and Dong Zhifei and Tang Boyuan hurriedly put down their work and started computer-related information.

"I rubbed it, scared Lao Tzu, I thought it was a big asteroid, at most it could only be regarded as a bigger rock."

After the calculation results, Tang Boyuan breathed a sigh of relief, according to the calculation results, this is an asteroid with a diameter of only a few tens of centimeters, and there are countless asteroids like this in the asteroid belt.

"Activate the rail cannon."

Luo Xiaoyao also breathed a sigh of relief here, he also knew that if a large asteroid was going to collide with the spacecraft, the best way for the spacecraft was to change the flight trajectory to dodge, whether it was a rail gun or a missile, it was not very safe for a large asteroid with a diameter of several hundred meters.

"Yes!"

Zhanfei quickly entered the command through the virtual machine, and at the same time sent an attack request to the Earth, and a few minutes later, the Earthside agreed to destroy the asteroid.

On the Dumbo spaceship, a long cannon barrel sticks out, the principle of the rail cannon is very simple, that is, to accelerate the launch of a hard object, usually a metal tungsten rod, etc., using Einstein's principle of mass energy formula, the faster the speed, the greater the energy carried, relying on this barbaric impact to bring powerful destructive power.

This kind of rail cannon can be regarded as a space-based weapon if it is fired from space to the earth, relying on the terrifying speed of the projectile, it is enough to achieve the terrible effect of destroying the world and destroying the earth, and it can easily destroy one city after another.

"Whew!"

The huge spaceship trembled, and a projectile was hidden in the pitch-black cosmic void environment, and flew out silently, in the cosmic void environment, its speed would not be reduced in the slightest, and the energy it carried would eventually be released on the target.

Everyone looked at the surveillance footage, which was the first time in human history that a weapon had been used to destroy another celestial body, even though it was only a few tens of centimeters in size, and it was just a small rock on Earth.

In the void, not too far from the Dumbo spacecraft, an asteroid is following its trajectory at a speed of tens of kilometers per second.

Suddenly, a projectile descended from the void and hit it with unmistakable accuracy, and in an instant, a huge amount of energy was released. It shattered in an instant, and was completely destroyed.

"Oh yes!"

Everyone on the spaceship immediately cheered, and they all relaxed one by one, there is no difficulty in destroying such an asteroid at all, and if you calculate the speed and trajectory of both sides, you can easily destroy it.

"This is probably the first time in human history that another celestial body has been destroyed, even if it is only a small stone."

Tang Boyuan touched his chin and said with a slight smugness.
