"The mass exceeds 300 million tons. It's such a pity. The Qinglong can't even drag it~"
Wu Renjie couldn't help but said regretfully.
"It is indeed a pity. This asteroid contains 40% iron and 30% copper. In total, more than 70% are metal elements. It can be said to be a very valuable asteroid."
Long Zhankong also nodded and said.
"Based on spectral image analysis, planets and meteorites in the asteroid belt can be roughly divided into three types. 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 their surfaces contain 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. , may be the result of differentiation due to the melting mechanism of the early solar system."
"The total number of m-type asteroids accounts for about 15%. Their spectra contain iron-nickel-like spectral lines, which appear white or slightly red, but have no absorption line characteristics. It is speculated that m-type asteroids should be made of The core is formed by a devastating impact with iron-nickel as the main matrix."
Huang Zhibin on the side also continued to popularize science and explain knowledge about asteroids to everyone.
Based on the spectral information detected by various instruments, scientists have a rough idea of the structure of planets and meteorites in the entire asteroid belt. This is a scientific method, and you can already know it clearly from thousands of miles away.
"The ones that really have a big impact on us are the smallest number of M-type asteroids. These asteroids contain a lot of metal resources. According to spectral detection, most asteroids are composed of silicon elements and can only be used for Making solar panels and stuff like that.”
"This asteroid is rich in more than 70% of metal elements. It is a 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 worth a fortune. "
"It's just that its mass is too big, we can't drag it, but it doesn't matter. I have saved its relevant information in the computer. When we have a more powerful spaceship in the future, we can come directly and drag it back. ."
Huang Zhibin smiled and said.
After everyone listened, they all understood immediately. At the same time, they also understood the reason why two astronomy scientists were brought on board the spacecraft.
Calculating the mass, volume, main elements of celestial bodies, etc., is a task that almost everyone majoring in astronomy can easily do, but for ordinary people, it is completely confusing and they don’t know what is happening thousands of kilometers away. Why can the mass of a star be calculated based on its distance?
"Keep moving forward and continue to release detection satellites around!"
After Wu Renjie received the report from Long Zhankong, he continued to issue orders to move forward.
The Qinglong 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.
Two days had passed since the first asteroid was discovered, and neither the detection radar nor the satellite found the second asteroid. Everyone was very depressed until the third day.
"Didi, didi, asteroid discovered, asteroid discovered."
Everyone on the ship was awakened by the system's alarm, and everyone quickly connected to the virtual machine.
"Haha, we have almost entered the center of the asteroid belt. The front was at the edge, and now dozens of asteroids have been discovered at once."
Information about dozens of asteroids came to mind, including how far they were from the spacecraft, in which direction, etc. Everyone on the spacecraft couldn't help but laugh happily.
"Long Zhankong, Huang Zhibin, the rest is up to you."
"Don't worry, I will definitely find the most suitable asteroid to take back."
Huang Zhibin grinned widely, and he and Long Zhankong 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. Long Zhankong and Huang Zhibin 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, Long Zhankong breathed a sigh of relief. According to the calculation results, this was an asteroid with a diameter of only a few dozen centimeters. There were countless asteroids like this in the asteroid belt, making it difficult to count.
"Activate the railgun."
Wu Renjie also breathed a 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!"
Deputy Liao Fanghong quickly input instructions through the virtual machine and sent an attack request to the Earth. A few minutes later, the Earth Command Center agreed to destroy the asteroid.
On the Qinglong 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 principle.
, the faster the speed, the greater the energy it carries, relying on this brutal impact to bring powerful destructive power.
"call out!"
The huge spaceship trembles. A projectile is hidden in the dark void environment of the universe and flies away silently. In the void environment of the universe, its speed will not decrease at all, and the energy it carries will eventually be on the target.
Release it.
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 that big on Earth.
Just stones.
In the void not too far away from the 'Qinglong' spacecraft, an asteroid is moving according to its own trajectory at a speed of tens of kilometers per second.
Suddenly, a projectile descended from the void and hit it accurately. In an instant, all the huge energy was released, and it instantly shattered and was completely destroyed.
"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."
Wu Renjie touched his chin and said slightly proudly.
"No, the asteroid numbered M0218 is no good. Its diameter exceeds 1,270 meters. Although more than 80% of it is made of iron elements, 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, get rich, get rich."
Huang Zhibin excitedly sent the information about an asteroid to Long Zhankong. At the same time, he looked like a money man, drooling and yelling.
"If you two have something good to share, don't just worry about your own happiness."
"That's right, how do you get rich?"
The other team members also spoke one after another, but unfortunately they and others could not understand the spectral data, nor could they analyze the mass and composition of asteroids, etc., so they could only stare.
"I'm going to make a fortune. Most of the elements in this asteroid numbered M0153 are gold. Oh my god, this is an asteroid made of gold."
"Damn it, its mass is too big, more than 200 million tons, it is not something we can eat at all."
Long Zhankong was very happy at first. If he could bring back an asteroid full of gold, the whole earth would completely explode. But when he calculated the mass of the asteroid, he couldn't help but curse.
"I'm going!"
When other people heard this, they were like deflated balloons.
"But it doesn't matter. I will record its detailed data here. We will be able to drag it around in the future."
Huang Zhibin smiled and very seriously recorded the data of the asteroid in the computer to facilitate future mining of the asteroid. Such an asteroid rich in gold is definitely not to be missed.
"The mass of this asteroid is only 50 million tons. We can definitely drag it, but its mass is too small, and its basic element is silicon, which has little value."
"The mass of this asteroid exceeds 200 million tons. Although it is basically made of iron elements and is very valuable, it exceeds our ultimate capabilities."
Long Zhankong and Huang Zhibin were very patient in calculating the mass and composition elements of each asteroid. Anyway, there were more and more asteroids around, and there were plenty of opportunities to choose from.
"Everyone, hurry up and take a look. An asteroid with a diameter of about 1,000 meters was found 3,682 kilometers ahead of us. According to the spectral wavelength and color position, this asteroid is actually made of iron elements. This asteroid
The weight is about 150 million tons, which is definitely our best goal."
Huang Zhibin seemed to have discovered a new continent and said to everyone very excitedly.
