"Zheng He" has been staying on Mars for more than half a month, searching all the entire Mars, digging out all suspicious places, and discovering several large black crystal minerals. As for the small ones, there are many of them. All of these mineral sites have been recorded one by one. In the future, after large-scale development of Mars, these black crystal minerals can be excavated.

Of course, many black crystal mines must have been dug in half a month. These black crystals were transported back to the earth by a large space shuttle. The scientists on the earth had long been hungry and unbearable!

"Report that all personnel and equipment have been evacuated from Mars!"

Li Jun nodded and it was time to leave after staying on Mars for more than half a month. Apart from discovering black crystal ore, Mars had few other gains. However, these high-quality black crystals on Mars are priceless treasures. As long as these black crystals are mined, Qingquan Technology will have countless energy blocks, which greatly promotes the development of science and technology.

"Notify everyone and prepare to set off again, next stop, asteroid belt!"

The huge "Zheng He" still relies on the gravity of Mars to obtain a greater initial velocity. After flying around Mars for a few laps, it flew to the outside of the solar system.

The average distance between Mars and the Sun is 1.5 astronomical units, and the distance between the asteroid belt and the Sun is 2.17-3.64 astronomical units.

The asteroid belt is a dense asteroid area in the solar system between the orbits of Mars and Jupiter. It is calculated from more than 120,000 asteroids that have been numbered, and 98.5% of asteroids have been discovered here. Since this is the densest area of ​​asteroids, it is estimated that there are as many as 500,000. This area is therefore called the main belt, usually called the asteroid belt.

Don’t look at the number of asteroids, but there are more than 120,000 numbers that have been numbered. There are probably as many as ox-haired ones. Most people think that this place is like the meteorite belt in the movie, and you can encounter countless meteorites and asteroids with just one move.

On the contrary, although there are a lot of meteorites in these planets, there are really many meteorites. A stone the size of a fist is also a meteorite, but if placed in the vast area surrounding the solar system, the density will be very small. The material in the asteroid belt is very thin. In history, several spacecraft have passed safely without accidents.

After flying in lonely and cold space for nearly ten days, the huge "Zheng He" has begun to enter the asteroid belt.

Although the material density here is also very low, after all, it is within the asteroid belt. All exploration tools on the Zheng He are turned on and a large number of microsatellites are launched.

"Start small detection satellites to scan the radiation, temperature, material composition, interstellar dust and matter distribution, magnetic field, and especially Jupiter's impact on the magnetic field here. You must know that Jupiter's magnetic field is the most terrifying thing in the entire solar system!"

"Open x-ray detection, gamma ray detection, β-ray detection, infrared radiation detection, magnetic field detection!"

"Open 3D stereo radar to produce 3D stereo images!"

"Open the laser cannon, and the weapon use authorization will be approved and can be used normally!"

"The nuclear weapons and missiles are activated, and no authorization for use is obtained!"

...

All the people and equipment of the "Zheng He" are operating at high speed, and the senior management on the earth who have sufficient authority can authorize the use of nuclear weapons to the "Zheng He" at any time.

Although the asteroid belt is very sparse, people on Qingquan Technology dare not take it lightly. You should know that in space, if a high-speed meteorite and the "Zheng He" collide, even if it is a very small meteorite, the consequences will be unimaginable, and no one dares to take it lightly.

After all the detection instruments were activated, all the situations within a range of tens of thousands of kilometers around the "Zheng He" were clearly displayed in the 3D stereoscopic image, even a small stone as small as a few centimeters could be detected.

And all the asteroids that may affect the Zheng He and meteorites are all shown by the red eye targets. The laser cannons installed on the Zheng He are constantly firing, smashing all of these targets into pieces.

"This is the fifth meteorite that was destroyed!" The Zheng He, which has all entered the asteroid belt, flew all the way and destroyed five asteroids. Moreover, these five asteroids were only considered to be threatening, so they were destroyed. It can be seen that the material density of the asteroid is not very high.

"Always be alert and don't take it lightly!"

Li Jun led the defense forces on the Zheng He to pay attention to everything about asteroids at all times. He did not dare to be careless about all dangerous meteorites.

On the other hand, scientists led by Jiang Zhipeng are also busy, constantly analyzing various meteorites and planets in the asteroid belt.

"According to spectral image analysis, meteorites in the asteroid belt can be roughly divided into three types. The ones that account for more than 60% of all asteroids are C-type asteroids rich in carbon values!"

"The number of S-type asteroids containing silicon accounts for about 25%. The spectrum shows that their 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, which may be due to the early melting mechanism of the solar system, resulting in differentiation results."

"The total number of M-type asteroids accounts for about 15%. Their spectrum contains iron-nickel-like spectral lines, which are white or slightly red, but have no characteristics of absorption lines. According to speculation, M-type asteroids should be formed by devastating impacts of iron-nickel as the dominant parent of the core."

Based on the spectral information detected by various instruments, scientists have roughly numbers of planets and meteorite structures in the entire asteroid belt. This is a scientific method, and you can already know it clearly from thousands of miles away.

"It seems that the number of M-type asteroids that really have a big effect is the smallest number of M-type asteroids. These asteroids contain a large amount of metal resources. Most asteroids are made of silicon elements according to spectral detection! They can only be used to make solar panels and other things!"

Jiang Zhipeng looked at the data that had been counted and frowned slightly. The amount of asteroid resources largely determines the future development of mankind.

"Everyone quickly take a look. A asteroid with a diameter of about 800 meters was found 2,270 kilometers ahead of us. According to the spectral wavelength and color position, this asteroid is actually made of iron elements! The weight of this asteroid is between 150 million and 200 million tons. If this asteroid is pulled down to the earth's space, how much can it be sold?"

A scientist in charge of detection was drooling at the asteroid in his computer!
