Chapter 210 (1/2)

Before this exploration activity, scientists launched several man-made satellites in advance to try to find minerals exposed on the surface through remote sensing technology. Over the past few days, more than half of the data of the whole planet have been collected, and many minerals have indeed been found.

However, people have high requirements for minerals, not only in terms of abundance, but also in terms of transportation. The distribution points of mineral resources can not be one in the East and one in the West. If each place is separated by thousands of kilometers, it is very troublesome to transport. It is best to concentrate in an area within a radius of 100 kilometers. In this way, it will be much easier to lay the railway.

Through satellite detection, the accuracy will decrease with the increase of depth. Most minerals on the planet are hidden underground, so we still have to rely on another simple technology - Planet impact!

By dropping heavy objects from high altitude, rapidly impacting the planet, and then analyzing the raised dust, we can get the specific composition of rock and soil.

Among them, the most critical minerals are water resources and organic matter.

In theory, the planet is not short of metal, but only these two.

”The temperature difference on the planet's surface is too large, and there can be no water on the surface... So water resources are likely to be hidden in the deeper surface in the form of ice. We have found a large number of ice mines in the north and south poles of the planet. But the north and south poles are too far from the stop point of the spacecraft, and the transportation is not convenient enough. ”

”As for organic compounds, it is the top priority of this detection. No matter the production of carbon fiber, or the growth and development of plants, humans and animals, all need the support of organic matter... ”

On the display screen, a hostess is broadcasting the planetary impact experiment. Many ordinary people gathered in the central square, waiting for this exciting result.

Satellite 1 is similar to the moon. Theoretically, a small amount of organic matter exists. However, if there is no large-scale enrichment, it is too difficult for human development, and the economic value will be greatly reduced.

It's impossible to go to the life planet next door to mine organic matter. All kinds of microorganisms are enough for humans to eat a pot.

Seeing the satellite fly away, Zhang Yuan was a little nervous: ”should it be all right?”

A scientist nearby said, ”it's hard to say. If we can't find these two ore sources for a long time, our development speed will slow down a lot...”

”Changing the planet is even more troublesome.”

Other planets have their own advantages and disadvantages. They are either too close to stars, or lack some elements, or geological activities are very intense. Up to now, there will be volcanic eruptions and earthquakes.

In addition, these artificial satellites are brought from the earth. Once launched, it will be very difficult to recycle them. At that time, without man-made satellites, the exploration of other planets can only rely on manual exploration, and the efficiency will be greatly reduced.

”The movement of the Mothership will also consume a lot of fuel. Alas, it's better to succeed at one time... ”

Zhang Yuan prayed silently in his heart for a while, and then stared at the big screen.

As the experiment went on, the commentator next door began to speak faster: ”audience friends... As you can see, the satellite has approached the first target area.”

”According to the estimates of experts, it was a super volcano billions of years ago. As we all know, volcanic eruptions may exhale a large amount of material, which will also be accompanied by some organic matter and sulfur compounds... This is a very good place to choose... ”

”The experiment has begun!”

In the screen, an iron ball was suddenly thrown from the satellite. After a long free fall, the speed of the iron ball became faster and faster

In an instant, the iron ball fell to the ground, because there was no deceleration of air, and its energy was comparable to that of a high explosive bomb, enough to raise huge dust.
