"Zheng He" has been staying here on Mars for more than half a month, looking for the whole of Mars, excavating all suspicious sites, and discovering several large black crystal minerals, as for the small ones, there are many of them, all of these mineral locations have been recorded one by one, and these black crystal mines can be excavated after large-scale development of Mars in the future.

Of course, half a month must have excavated a lot of black crystals, which were transported back to Earth by a large space shuttle, and the scientists on the other side of the earth were already hungry and thirsty~ unbearable!

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

Li Jun nodded, it is time to leave after staying on Mars for more than half a month, except for the discovery of black crystal ore on Mars, there are few other harvests, but 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 will greatly promote the development of science and technology.

"Inform everyone, get ready to start again, next stop, the asteroid belt!"

The huge "Zheng He" still relies on the gravitational pull of Mars to gain greater initial velocity, and after flying around Mars a few times, it flies in the direction of the outer solar system.

The average distance of Mars from the Sun is 1.5 AU, and the distance of the asteroid belt from the Sun is 2.17-3.64 AU in space.

The asteroid belt is a dense area of asteroids in the solar system between the orbits of Mars and Jupiter, which has been counted by more than 120,000 asteroids that have been numbered, and 98.5% of the asteroids have been found here. Since this is the region with the highest concentration of asteroids, estimated to number as many as 500,000, this area is known as the main belt, commonly known as the asteroid belt.

Don't look at the number of asteroids, there seem to be a lot of them, there are more than 120,000 of them that have been numbered, and there are more than 120,000 of them, and there are as many as cattle hair that are not numbered.

The reality is just the opposite, although the number of these planets and meteorites is very large, really a lot, a fist-sized stone is also a meteorite, but if it is placed in the vast area around the solar system, this density is very small, the material in the asteroid belt is very thin, and there have been several spaceships in history that have passed safely without accidents.

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

Although the density of materials here is also very low, after all, within the asteroid belt, all the exploration tools on the "Zheng He" have been turned on, and a large number of microsatellites have been launched.

"Send a small exploration satellite to scan the radiation, temperature, material composition, interstellar dust material distribution, magnetic field, 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 inspection, γ-ray inspection, β-ray inspection, infrared radiation detection, magnetic field detection!"

"Turn on the 3D stereo radar and produce 3D stereo images!"

"Turn on the laser cannon, the weapon use authorization has been approved, and it can be used normally!"

"Turn on the nuclear missile, without authorization to use it!"

……

All the personnel and equipment of the "Zheng He" are operating at high speed, and there are also high-level officials on the other side of the earth who have sufficient authority to authorize the use of nuclear weapons to the "Zheng He" side at any time.

Although the material in the asteroid belt is very sparse, the people on the side of Qingquan Technology do not dare to take it lightly, you must know that in space, if the high-speed meteorite collides with the "Zheng He", even if it is a small meteorite, the consequences are unimaginable, and no one dares to take it lightly.

After all the detection instruments were activated, all the conditions within tens of thousands of kilometers around the "Zheng He" were clearly displayed in the 3D stereoscopic image, even if it was a small stone as small as a few centimeters.

And all the asteroids and meteorites that may affect the "Zheng He" are all highlighted by the red eye-catching targets, and the laser cannons installed on the "Zheng He" are constantly fired, smashing all these targets to pieces.

"This is the 5th meteorite to be destroyed!" The "Zheng He", which has all entered the asteroid belt, flew all the way and only destroyed 5 asteroids, and these 5 asteroids were only destroyed when they were considered to pose a possible threat, which shows that the material density of the asteroids is not large.

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

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

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

"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 C-type asteroids rich in carbon value!"

"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. ”

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.

"It seems that the least number of M-type asteroids have a big effect, and these asteroids contain a lot of metal resources, and most of the asteroids are composed of silicon elements according to spectral detection! It can only be used to make things like solar panels! ”

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

"Let's take a look, an asteroid with a diameter of about 800 meters was found 2270 kilometers in front of us on the left, and according to the spectral wavelength color position, this asteroid is all made of iron! This asteroid weighs between 150 million and 200 million tons, and if this asteroid were pulled down to the Earth's side of space, how much would it sell for? ”

A scientist in charge of the exploration looked at the asteroid in the computer with drooling!
