Universe dominance

Inside the Dumbo spacecraft, the ten crew members were all busy with their own affairs. Some were contacting their families on Earth. Although the speed of electromagnetic waves was comparable to the speed of light, the distance from the region was more than 1 astronomical unit. At the speed of light, a one-way delay of nearly 8 seconds was required, and a round trip delay of more than ten seconds was required. The information received now was the information sent from Earth more than ten seconds ago. Traditional electromagnetic communication technology did not have much problem on Earth, but once it entered the interstellar universe, it could no longer meet the needs of development. This was only in a very small area in the solar system. Despite the long delay in the call, the crew members were still happy to contact their relatives and friends on Earth, because the long journey was too boring. The scenery outside the spacecraft seemed to be eternal, with stars dotted in the black starry sky. These lights that had arrived after who knows how many years had passed, and the source of the light had already changed a lot. Some people contacted their relatives and friends on Earth, and some slept and read quietly in the plant area. After a long interstellar journey, the anxiety and irritability in their hearts became more and more serious. Only by taking a good rest in the plant area can the negative emotions in their hearts be relieved.

Others kept exercising in the gym. Everyone knew that if they wanted to live a healthy life after returning to Earth, the time and intensity of this exercise could not be discounted at all. This was not for others, but for themselves.

In mid-April 2022, the spacecraft flew over the orbit of Mars, but Mars was on the other side very far away at this time. Otherwise, it would be possible to take a good look at the appearance of Mars. After crossing the orbit of Mars, the distance to the asteroid belt was already very close.

"Captain Luo, we need to slow down the spacecraft now!"

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

"What does the Earth say?"

Luo Xiaoyao nodded. According to the plan, it was almost time to start slowing down, but he still had to listen to the opinions of the command center on Earth.

"The same is true for Earth. Start slowing down."

Tang Boyuan nodded and conveyed the meaning of Earth. The supercomputer has simulated all possibilities.

"Start slowing down!"

Luo Xiaoyao nodded and began to give orders.

The huge Dumbo spacecraft is equipped with a reverse plasma engine at the front and back for deceleration. At this time, the two engines started working, ejecting reverse tail flames, and the speed of the spacecraft began to slowly decrease.

"Turn on x-ray detection, gamma ray detection, beta ray detection, infrared radiation detection, and magnetic field detection!"

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

"Turn on the weapon system and be on standby at any time."

"Launch unmanned detection satellite."

Commands were issued from Luo Xiaoyao one by one. The asteroid belt that was about to arrive was not a warm and empty void. It could be hit by an asteroid at any time, so the detection radar must be turned on. In order to save energy before, it was not turned on.

At the same time, the weapon system is also on standby at any time. Spacecraft flying in the void of the universe usually fly in a straight line. If the flight trajectory is changed to avoid the impact of meteorites and asteroids, the energy consumed will be very amazing, especially when the mass of the spacecraft is larger, the energy consumed will be greater.

So in general, the method of destroying the meteorites and asteroids in front will be adopted, and weapons will be used to destroy them. The Dumbo spacecraft carries two weapons, rail guns and missiles, and there is definitely no problem in dealing with ordinary asteroids.

As for the unmanned exploration satellites released, they are to grasp the situation of a large range of voids as much as possible. These exploration satellites are very cheap, disposable products, and the number is relatively large. It is also in order for Fuyun Group to grasp more of the situation in the solar system, so some unmanned exploration satellites will be continuously released along the way.

The crew on the spacecraft also began to get busy, starting to repair the spacecraft and equipment, conducting emergency drills, etc., and at the same time they are full of expectations for the asteroid belt that is about to arrive.

As the days passed, the speed of the spacecraft became slower and slower, and it was getting closer and closer to the asteroid belt.

"Ding, an asteroid was found."

In early June, the detection radar on the Dumbo spacecraft finally found the first asteroid. Suddenly, everyone on the ship became excited. They finally arrived at the asteroid belt.

"This asteroid is 5,980 kilometers away from us. According to the spectral image analysis sent by the detection satellite, its main components are 40% iron, 30% copper, and the rest are basically silicon."

"Its diameter is more than 456 meters, and the overall shape is irregular. The mass is more than 300 million tons. It is not our cup of tea."

In Tang Boyuan's mind, the virtual machine directly transmits the relevant information to his brain. He analyzes the data and quickly obtains the relevant information of this asteroid.

Calculating the mass, volume, main elements of celestial bodies, etc. is a job that almost every student majoring in astronomy can easily do, but for ordinary people, it is completely confusing. I don't know why the mass of a star can be calculated at a distance of thousands of kilometers.

"Keep moving forward and continue to release detection satellites around!"

After Luo Xiaoyao received Tang Boyuan's report, he continued to issue orders to move forward.

The Dumbo spacecraft continued to fly in the void. The speed at this time was already quite slow, only a dozen kilometers per second. The detection satellites on the spacecraft spread out in all directions for free.

Although the asteroid belt is called an asteroid belt and contains countless asteroids, they are distributed over such a vast area. When you are really in it, you will still feel that the asteroid belt is very empty.

Three days had passed since the first asteroid was discovered. Neither the detection radar nor the satellite found the second asteroid. Everyone was very depressed until the fourth day.

"Didi, didi, asteroid discovered, asteroid discovered."

Everyone in the spaceship was awakened by the system's alarm, and each one quickly connected to the virtual machine.

"Haha, we have almost entered the center of the asteroid belt. In front of us is the edge. We have discovered dozens of asteroids at once."

Luo Xiaoyao couldn't help but laugh happily as information about dozens of asteroids came into his mind, including how far away they were from the spacecraft, in which direction they were, etc.

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

"Don't worry, I will definitely find the most suitable asteroid to take back."

Dong Zhifei grinned widely, and he and Tang Boyuan began to use computers to analyze these asteroids, calculating their mass, volume, direction, distance, speed, composition elements, etc.

"Buzz, buzz, alarm, alarm, the trajectory of an asteroid is about to coincide with the flight trajectory of the spacecraft, please deal with it immediately."

At this moment, the warning sound on the spacecraft blared loudly. Upon hearing this, everyone's faces became serious. Dong Zhifei and Tang Boyuan quickly put down their work and started to computer-related information.

"Oh no, I was shocked. I thought it was such a big asteroid. It can only be regarded as a larger rock at most."

After calculating the results, Tang Boyuan breathed a sigh of relief. According to the calculation results, this is an asteroid with a diameter of only a few dozen centimeters. There are not countless asteroids like this in the asteroid belt.

"Activate the railgun."

Luo Xiaoyao also breathed a heavy sigh of relief. He also knew that if a large asteroid was to collide with the spacecraft, the best way for the spacecraft would be to change its flight trajectory to avoid it. Whether it was a rail gun or a missile with a diameter of several hundred Large asteroids are not very safe.

"yes!"

Zhan Fei quickly input instructions through the virtual machine and sent an attack request to the Earth. A few minutes later, the Earth agreed to destroy the asteroid.

On the Dumbo spacecraft, a long barrel stretches out. The principle of the rail gun is very simple. It is to accelerate and launch a hard object, usually a metal tungsten rod, etc., using Einstein's mass-energy formula. The principle is that the faster the speed, the greater the energy it carries. This brutal impact brings powerful destructive power.

This kind of rail gun 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 can achieve the terrifying effect of destroying the world and destroying cities easily. Er Jing.

"call out!"

The huge spaceship trembled. A projectile was hidden in the dark void environment of the universe and flew away silently. In the void environment of the universe, its speed would not decrease at all, and the energy it carried would eventually be released on the target. come out.

Everyone looked at the surveillance screen. This could be regarded as the first time in human history that weapons were used to destroy another celestial body. Although it was only an asteroid a few dozen centimeters in size, it was not a big one on Earth. Just stones.

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

Suddenly, a projectile descended from the void and hit it accurately. In an instant, all the huge energy was released. It instantly shattered into pieces and was completely destroyed.

"Oh yeah!"

Everyone on the spacecraft immediately cheered, and everyone felt relieved. It was not difficult to destroy such an asteroid. By calculating the speed and trajectory of both parties, they could easily destroy it.

"This should be regarded as the first time in human history that other celestial bodies have been destroyed, even though it was just a small stone."

Tang Boyuan touched his chin and said slightly proudly.
