"The mass is more than 300 million tons, it's a pity, the Qinglong can't be dragged at all~"

Wu Renjie couldn't help but say regretfully.

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

Long Zhankong also nodded and said.

"According to the analysis of spectral images, 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 silicon-containing S-type asteroids is about 25%, and the spectra show that their surface contains silicates and some metals, but the composition of carbonaceous compounds is not obvious. This suggests that they are significantly different from the composition of the original solar system, possibly due to the melting mechanism of the early solar system, which led to the result of differentiation. ”

"The total number of M-type asteroids accounts for about 15%. Their spectra contain iron-nickel lines, white or slightly red, and no absorption lines, and M-type asteroids are presumed to have been formed by a devastating impact with an iron-nickel core of the parent body. ”

Huang Zhibin on the side also continued to popularize science to everyone and explain asteroid-related knowledge.

Scientists have an approximate number of planets and meteorite structures in the entire asteroid belt based on the spectral information detected by various instruments, which is the means of science, and it is already clear to you thousands of miles away.

"What really makes a big difference to us is the least number of M-type asteroids, which contain a lot of metal resources, and most of the asteroids are made of silicon according to spectral detection, and can only be used to make solar panels and the like."

"This asteroid is rich in more than 7 percent of metal elements, it is a typical M-type asteroid, and what is even more rare is that its metal content is very high, if it can be dragged back to the earth, it is absolutely valuable."

"It's just that it's too massive for us to tow, but it doesn't matter, I've saved information about it in my computer, and when we have a more powerful spaceship in the future, we can directly come and haul it back."

Huang Zhibin said with a smile.

After listening to this, everyone immediately became clear one by one, and at the same time, they also understood the reason why they brought two cosmic astronomical scientists on the spacecraft.

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 Wu Renjie got Long Zhankong's report, he continued to give the order to advance.

The Qinglong spacecraft continued to fly in the void, and the speed at this time 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.

Two 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 third day.

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

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

"Haha, we're almost in the center of the asteroid belt now, with the edge in front of us, and now we've discovered dozens of asteroids at once."

The information of dozens of asteroids in their minds came to mind, how far away from the spaceship, in that direction, etc., and the people on the entire spacecraft couldn't help but laugh happily.

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

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

Huang Zhibin grinned and began to fight with Long Zhankong, 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 Long Zhankong and Huang Zhibin 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, Long Zhankong 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 asteroids like this are simply countless and difficult to count in the asteroid belt.

"Activate the rail cannon."

Wu Renjie 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 its 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!"

Deputy Liao Fanghong quickly entered the command through the virtual machine, and at the same time sent an attack application to the earth, and a few minutes later, the earth command center agreed to destroy the asteroid.

On the Qinglong spacecraft, a long cannon barrel stretched 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.

"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 decrease 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 Qinglong spacecraft, an asteroid is following its trajectory at a speed of tens of miles per second.

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

"Yay!"

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."

Wu Renjie touched his chin and said with a slight smugness.

"The asteroid numbered M0218, no, its diameter is more than 1,270 meters, although more than 80% of it is iron, but its mass has far exceeded the limit that our spacecraft can drag, and the mass has reached more than 200 million tons."

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

"Look at this, get rich, get rich."

Huang Zhibin excitedly sent the information of an asteroid to Long Zhankong, and at the same time, the whole person looked like a little money fan, drooling, and shouting in his mouth.

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

"That's it, what kind of fortune?"

The other team members also spoke one after another, but they couldn't understand the spectral data, nor could they analyze the mass and composition of the asteroid, so they could only stare dryly.

"I'm going~ I'm really rich, this asteroid number M0153 turns out that most of the elements are gold, oh my God, this is simply an asteroid made of gold."

"Damn, it's so big, more than 200 million tons, it's not a dish we can eat at all."

Long Zhankong was still very happy, if he could bring back an asteroid full of gold, the entire earth would completely explode, but as soon as he calculated the mass of this asteroid, the whole person couldn't help but scold.

"I'll go!"

When the others heard it, it was like a deflated balloon.

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

Huang Zhibin smiled, and recorded the data of this asteroid in the computer very seriously, so as to facilitate the mining of the asteroid in the future, such an asteroid rich in gold is definitely not to be missed.

"The mass of this asteroid is only 50 million tons, and we can drag it, but its mass is too small, and basically the elements it is composed of silicon, which has no value."

"This asteroid has a mass of more than 200 million tons, and although it is basically made of iron, it is very valuable, but it exceeds our limits."

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

"Let's take a look, we found an asteroid with a diameter of about 1,000 meters at 3,682 kilometers in front of us, according to the spectral wavelength color position, this asteroid is all composed of iron, and the weight of this asteroid is about 150 million tons, which is definitely our best target."

Huang Zhibin seemed to have discovered a new continent, and said to everyone very excitedly.
