"It's a pity that the quality is more than 300 million tons. The Qinglong can't move at all ~"

Wu Renjie could not help but regretfully said.

"It's really a pity that this asteroid contains 40% iron and 30% copper. Together, more than 70% are metallic elements. It can be said to be a very valuable asteroid."

Dragon War Air nodded likewise.

"According to spectral image analysis, the planets and meteorites in the asteroid belt can be roughly divided into three types, and more than 60% of all asteroids are carbon-rich C-type asteroids."

"The number of S-type asteroids containing silicon accounts for about 25%. The spectrum shows that the surface contains silicates and some metals, but the composition of carbonaceous compounds is not obvious. This shows that they are significantly different from the composition of the original solar system. Probably due to the early melting mechanism of the solar system, resulting in differentiation. "

"M-type asteroids account for about 15% of the total. Their spectra contain iron-nickel-like lines, which are white or slightly red, without the characteristics of absorption lines. M-type asteroids are supposed to be caused by The core is made of iron-nickel as the main precursor after a devastating impact. "

Huang Zhibin on the side also continued to carry out science popularization to everyone, explaining the knowledge about asteroids.

Based on the spectral information detected by various instruments, scientists have roughly estimated the structure of the planets and meteorites in the entire asteroid belt. This is the scientific method, and it is clear to you far away.

"The ones that really have a big effect on us are the smallest number of M-type asteroids. These asteroids contain a lot of metal resources. Most asteroids are based on spectral detection and are composed of silicon elements. They can only be used for Make things like solar panels. "

"This asteroid is rich in more than 70% of the metal elements. It belongs to the typical M-type asteroid. What is even more rare is that its metal content is very high. If it can be dragged back to Earth, it will be absolutely valuable. "

"It's just too big. We can't move it, but it doesn't matter. I have stored information about it in the computer. After we have a more powerful spaceship, we can just come over and haul it back. . "

Huang Zhibin said with a smile.

After listening to everyone, it became clear one by one. At the same time, they also understood the reason for bringing two space astronomy scientists on the spacecraft.

Calculating the mass, volume, and main elements of celestial bodies, etc. This is almost a job that everyone in the astronomy department can easily do, but for ordinary people, it is completely scratchy. I don't know that they are thousands of kilometers apart. Distance can calculate the mass of the stars and so on.

"Go ahead and release the sounding satellites around!"

After Wu Renjie got the report from Long Zhankong, he continued to give orders.

The Qinglong spacecraft continued to fly in the void. At this time, the speed was already quite slow, only a dozen kilometers per second. The detection satellites on the spacecraft were not broadcasted in all directions.

Although the asteroid belt is said to be an asteroid belt, there are countless asteroids, but it is distributed in such a wide range. When you are really in it, you will still feel that the asteroid belt is very empty.

Two days have passed since the first asteroid was discovered, and neither the detection radar nor the satellite discovered the second asteroid, and they were very depressed until the third day.

"Didi, didi, discover asteroids, discover asteroids."

The entire ship was awakened by the system's sirens and quickly connected to the virtual machine one by one.

"Haha, we are almost into the off-center position of the asteroid belt. The front is the edge position. Now we have dozens of asteroids."

The information of dozens of asteroids in my mind reflected in my mind, how far away from the spacecraft, in that direction, etc., the people on the entire spaceship couldn't help laughing.

"Long Zhankong, Huang Zhibin, it's up to you."

"Rest assured, I must find the most suitable asteroid to take home."

With a big mouth, Huang Zhibin started to fight with Dragon Fighter in half. He used a computer to analyze these asteroids and calculate their mass, volume, direction, distance, speed, composition elements, and so on.

"Om, hum, sirens, sirens, there is an asteroid's trajectory that is about to coincide with the spacecraft's trajectory, please handle it immediately."

At this moment, the warning sound on the spacecraft was so loud that everyone's faces became serious one by one. Long Zhankong and Huang Zhibin quickly put down their work and started computer-related information.

"I rubbed and scared Lao Tzu. I thought it was an asteroid, at best, it can only be regarded as a larger stone."

After calculating the results, Long Zhankong let out a sigh of relief. According to the calculation results, this is an asteroid with a diameter of only tens of centimeters. Similar asteroids in this asteroid belt are countless and difficult to count.

"Start the railgun."

Wu Renjie is also relieved. He also knows that if a large asteroid is going to collide with the spacecraft, the best way for the spacecraft is to change the flight path to avoid it, whether it is a railgun or a missile. Large asteroids are not very safe.

"Yes!"

The deputy Liao Fanghong here quickly entered instructions through the virtual machine and sent an attack application to the Earth side. A few minutes later, the Earth Command Center agreed to destroy the asteroid.

Above the Qinglong spacecraft, a long cannon sticks out. The principle of the rail gun is very simple. It is to accelerate the launch of a hard object, usually a metal tungsten rod, etc., using the principle of Einstein's mass energy formula. The faster the speed, the greater the energy carried, relying on this brutal impact to bring powerful destructive power.

"call out!"

The huge spaceship trembles, a projectile is hidden in the dark universe, and it flies away silently. In the universe, the speed will not decrease in the slightest, and the energy it carries will eventually be on the target. Release it.

Everyone is looking at the monitoring picture. This can be regarded as the first time in human history to use weapons to destroy another celestial body, although it is only an asteroid with a size of several tens of centimeters, and it is not much on earth. Just a stone.

In the void not too far from the 'Qinglong' spacecraft, an asteroid is moving at a speed of tens of kilometers per second in accordance with its own trajectory.

Suddenly, a projectile came down from the void and hit it without any errors. In a split second, the huge energy was released, and it instantly shattered and was completely destroyed.

"Yay!"

The people on the spacecraft immediately cheered, and all of them were relieved. There is no difficulty in destroying such an asteroid. After calculating the speed and trajectory of the two sides, it can be easily destroyed.

"This should be the first time in human history to destroy other celestial bodies, although it is only a small stone."

Wu Renjie touched his chin and said slightly proudly.

"This asteroid number M0218 will not work. Its diameter exceeds 1270 meters. Although more than 80% are iron, its mass has far exceeded the limit that our spacecraft can drag. The mass has reached 2 More than 100 million tons. "

Long Zhankong and Huang Zhibin were looking for suitable targets at this time. As the spacecraft gradually entered the core area of ​​the asteroid belt, more and more asteroids were discovered.

"Look at this one, you're rich, you're rich."

Huang Zhibin was excited to send the information of an asteroid to Dragon War Air, and at the same time, the whole person looked like a small fortune fan, drooling and sulking in his mouth.

"You two have something good to share, but don't just care about yourself."

"That is, what money do you make?"

The other team members also started to talk one after another, but they couldn't understand the spectral data themselves, and they couldn't analyze the mass and composition of the asteroid. They could only stare.

"I'm going ~ I'm really rich. Most of the elements of this asteroid M0153 are gold, oh my **** ~ lightnovelpub.net ~ This is just an asteroid made of gold."

"Fuck, its quality is too big, more than 200 million tons, it's not what we can eat."

Dragon War Air was still very happy. If it could bring an asteroid full of gold back, the whole earth would explode completely, but the whole person couldn't help cursing it when calculating the mass of this asteroid.

"I go!"

Everyone else felt like a deflated balloon.

"But it doesn't matter, I will record its detailed data here, and we will always be able to drag it in the future."

Huang Zhibin smiled, and took the data of this asteroid very seriously in the computer to facilitate the future mining of the asteroid. Such a gold-rich asteroid must not be missed.

"The mass of this asteroid is only 50 million tons. We can drag it, but its mass is too small, and the element that is basically composed of silicon is of little value."

"This asteroid has a mass of more than 200 million tons. Although it is basically made of iron and is very valuable, it has exceeded our limit."

Long Zhankong and Huang Zhibin were very patient to calculate the mass and composition of each asteroid. Anyway, there are more and more asteroids around, and there are opportunities to choose.

"Let ’s take a quick look. We found an asteroid with a diameter of about 1,000 meters at 3682 kilometers in front of us. According to the spectral wavelength and color position, this asteroid turned out to be made of iron. It weighs around 150 million tons, which is definitely our best goal. "

Huang Zhibin seemed to have discovered the side of the New World and was very excited to say to everyone.
