A genius remembers "Love to go ÷ small? Speak → Net" in one second to provide you with wonderful novel reading.
"Zhenghe" has been staying here for more than half a month, searching the entire Mars, digging all suspicious locations, and finding several large black crystal minerals, as for the small ones, it is very Many of these mineral locations have been recorded one by one. After large-scale development of Mars in the future, these black crystal mines can be excavated.
Of course, a lot of black crystals must have been excavated in half a month. These black crystals were first transported back to the earth by a large space shuttle. Scientists on the earth have long been hungry ~ unbearable!
"Report, all personnel and equipment have been evacuated from Mars!"
Li Jun nodded. After spending more than half a month with Mars, it was time to leave. Mars had little other than discovering the black crystal ore, but these high-quality black crystals on Mars are priceless. These As long as the black crystals are mined, Qingquan Technology will have countless energy blocks, which will greatly promote the development of science and technology.
"Notify everyone, ready to start again, next stop, Asteroid Belt!"
The huge "Zhenghe" still relied on Mars' gravitational force to obtain a larger initial velocity. After flying around Mars a few times, it determined the direction of the outer periphery of the solar system.
The average distance between Mars and the Sun is 5 astronomical units, and the asteroid belt range is within the space area of ​​17-64 astronomical units.
The asteroid belt is a dense area of ​​asteroids between the orbits of Mars and Jupiter in the solar system. It is calculated from more than 120,000 asteroids that have been numbered. 5% of asteroids have been found here. Since this is the most dense area of ​​the asteroid, with an estimated number of 500,000, this area is therefore called the main belt, often called the asteroid belt.
Do n’t look at the number of asteroids. The numbered ones are more than 120,000. The number without an estimate is as much as a cow's hair. Most people must think that this place is like a meteorite belt in the movie. You can run into countless numbers when you move it. Meteorite, asteroid.
The reality is just the opposite. Although the number of these planets and meteorites is very large, there are really many. A fist-sized stone is also a meteorite, but if placed in the vast area surrounding the solar system, this density is very small. The asteroid belt The material is very thin, and several spacecraft have passed safely in history without accidents.
After the huge "Zheng He" flew in lonely, icy space for more than ten days, it has begun to enter the range of the asteroid belt.
Although the material density here is also very low, after all, it is within the asteroid belt. All the exploration tools on the Zhenghe are turned on, and a large number of micro satellites are launched.
"Launch a small exploration satellite and scan the radiation, temperature, material composition, interstellar dust material distribution, and magnetic field of the asteroid belt, especially the influence of Jupiter on the magnetic field here. You must know that Jupiter's magnetic field is the most terrifying in the entire solar system!"
"Turn on x-ray detection, gamma-ray detection, beta-ray detection, infrared radiation detection, magnetic field detection!"
"Turn on 3d stereo radar to produce 3d stereo images!"
"Turn on the laser cannon, the weapon use authorization is approved, and it can be used normally!"
"Turn on nuclear weapon missiles, unauthorized use!"
...
All the people and equipment of the "Zhenghe" are operating at high speed, and the high-level officials who have sufficient rights at random on the earth can authorize the use of nuclear weapons to the "Zhenghe" at any time.
Although the material of the asteroid belt is very sparse, people on the side of Qingquan Technology are not afraid to take it lightly. You must know that in space, if a high-speed flying meteorite and the "Zhenghe" collide, even a small one Meteorites have unpredictable consequences, and no one dares to take them lightly.
After all the detection instruments were activated, everything in the range of tens of thousands of kilometers around the "Zhenghe" was clearly displayed in the 3D stereo image, even small stones as small as a few centimeters could be detected.
And all the asteroids and meteorites that may affect the "Zhenghe" are shown by the red target, and the laser cannon mounted on the "Zhenghe" is continuously firing, and all these targets are shattered.
"This is the 5th meteorite destroyed!" Zheng He, which has entered the asteroid belt, flew all the way, and also destroyed 5 asteroids, and these 5 asteroids were only considered to be a threat. After being destroyed, it can be seen that the material density of the asteroid is not too large.
"Be vigilant at all times and don't take it lightly!"
Li Jun's side led the defense forces on the "Zheng He" to pay attention to all the asteroids at all times. They did not dare to carelessly destroy all dangerous meteorites and asteroids.
On the other side, scientists led by Jiang Zhipeng are also busy analyzing various meteorites and planets in the asteroid belt.
"According to the 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, which 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. "
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.
"It seems that the most important thing is the smallest number of m-type asteroids. These asteroids contain a lot of metal resources. Most of the asteroids are made of silicon based on spectral detection! They can only be used for Make things like solar panels! "
Jiang Zhipeng frowned slightly looking at the statistics that had been calculated. The amount of asteroid resources largely determines the future development of humankind.
"Let's take a quick look and find an asteroid with a diameter of about 800 meters at 2270 kilometers ahead of us. Based on the spectral wavelength and color position, this asteroid turned out to be all iron! This asteroid The weight is between 500 million and 200 million tons. If you pull this asteroid down to the side of Earth space, how much will it cost? "
A scientist in charge drooled at the asteroid in the computer!
