Chapter 747

He can understand that more detectors need to be launched in the future. If you want to get benefits, how can you do if you don't invest in the early stage? It's right to pour money into it, because these investments will bring rich returns to the company in the future!

Where is the asteroid belt? Asteroids are the most important members of small celestial bodies in the solar system. They are mainly composed of rocks and non volatile materials.

The major asteroid belts are located between the orbits of Mars and Jupiter, 2.3 to 3.3 astronomical units from the sun. They are considered to be residual materials that were disturbed by Jupiter's gravity during the formation of the solar system.

Asteroids range in size from hundreds of kilometers to microns. Except Ceres, the largest asteroid, all asteroids are classified as small objects in the solar system. However, several asteroids, such as Vesta and Jianshen, may be reclassified as dwarf planets if they can be proved to have reached hydrostatic equilibrium.

The asteroid belt has tens of thousands, possibly as many as millions, of small objects more than one kilometer in diameter. Nevertheless, the total mass of the asteroid belt is still unlikely to reach one thousandth of the mass of the earth.

At first glance, this figure seems to be very small, but we may not pay much attention to the weight of the earth we live in. The mass of the earth is 5.965 × 10 ^ 24kg, that is, 6 trillion tons. Even if the total weight of the asteroid belt is only one tenth of the earth's, its mass is 6 billion tons!

And with the technology that we have mastered at present, most of the materials in it can be used. Think about how much benefits there are!

The asteroid belt contains two main types of asteroids. At the outer edge of the asteroid belt, C-type asteroids with rich carbon value are the main ones near the orbit of Jupiter, accounting for more than 75% of the total.

Compared with other asteroids, they are reddish in color and have very low albedo. Their surface composition is similar to that of carbonaceous meteorites. Their chemical composition and spectral characteristics are the early state of the solar system, but they lack some lighter and volatile substances, such as ice!

The importance of ice to space exploration is not to mention. We all know that even if we only pull an icy asteroid to Mars, it can provide a source of life for future Martian colonies. It is better than sending so little water from the earth to Mars at a huge cost through a long voyage. After all, only when there is enough water, can the real colonization survive Hold on!

The inner part of the asteroid belt is 2.5 astronomical units away from the sun. Silicon containing S-type asteroids are more common. The spectrum shows that the surface of the asteroid belt contains silicate and some metals, but the composition of carbonaceous compounds is not obvious.

This indicates that they are significantly different from the composition of the primitive solar system, which may be due to the melting mechanism in the early stage of the solar system. Compared with C-type asteroids, such asteroids have high reflectivity. About 17% of the total population in the asteroid belt.

There is also a third type of asteroid, which accounts for about 10% of the total number of M-type asteroids. Their spectra contain Fe Ni like lines, showing white or slight red, without the characteristics of absorption lines.

The M-type asteroid is supposed to be formed by the destructive impact of iron nickel core. In the main belt, the M-type asteroids are mainly distributed in the orbit of 2.7 Au.

These asteroids are eye-catching. What is the most valuable thing in space? It must be these metals!

If the resources of the universe are compared to a large supermarket, the weight of the earth can only be regarded as the size of bread crumbs. The National Aeronautics and Space Administration of the United States once estimated that if the mineral wealth of the asteroids in the asteroid belt were distributed to the 6 billion people on earth, each person would get more than 100 billion US dollars.

A website called planet rankings has evaluated the value of 580000 known asteroids. Among them, "241 Germania" has the highest valuation. The value of its mineral resources is as high as 95.8 trillion US dollars, almost the same as last year's global GDP!

And these valuable things are lured there. Infinite gravitation group is not the first company that wants to do something with them. Many companies in the world have planned to go to asteroids to bring and exploit these resources. But at present, they are just thinking about it. If the technical strength is not up to the standard, it is just a vain idea to think about it!

Even if the infinite gravitation group has this plan, it will take at least several years to complete the first asteroid belt mining plan. It will take a long time to explore the asteroid belt alone. There are also the selection of suitable asteroids and the technology to pull it to the vicinity of Mars or the moon, step by step It's real.

If there is a mistake and the asteroid's orbit is aimed at the earth, it will be great fun. Therefore, even if we want to exploit such resources, we need to consider many things.

Of course, the economic benefits and the significance to the space program of the infinite gravitation group are extraordinary, and this step must be taken by the company.

Take the most basic carrying capacity. Even if the rocket carrying capacity of infinite gravity group is doubled in the future, the weight of materials that can be transported to space at one time will not exceed 200 tons.The cost of transporting these materials is at least 30 million US dollars, with an average of 150000 US dollars per ton, which is the internal price of infinite gravity group. You can't even talk about the external quotation of 300 million US dollars!

And how many metal dominated asteroids in the asteroid belt? At least 100000! If the weight is more than 100000 tons, at least 10000 will go up!

Not to mention other metals, take the most common iron asteroid as an example. After smelting a 10000 ton iron asteroid, at least 50000 tons will not be a problem. If we don't count the other iron, it will be worth 200 million at least. It seems that the money is not much.

But the value of these iron is not so calculated, which depends on where these iron is. It is very cheap on earth, but it will cost a lot of money to send them into space!

Even if infinite gravity wants to transport this 50000 tons of iron from earth to space, it will cost at least 7.5 billion dollars! Not to mention other countries or companies, maybe 50 billion dollars can not complete this mission!

It doesn't matter if you don't have money. After all, even if it's $7.5 billion, it will be over with the capital of infinite gravity group. However, the time cost should be taken into account. Even if a launch is 200 tons, 50000 tons will be launched 250 times, twice a day, it will take 125 days to complete the launch! 4 months!!!
