The expedition was preceded by the launch of several satellites to try to discover mineral deposits exposed to the surface through remote sensing. In the past few days, most of the data of the entire planet has been collected, and a lot of various minerals have indeed been discovered.

But people have high requirements for minerals, not only in terms of abundance, but also in terms of transportation, the distribution points of mineral deposits can not always 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, and it is best to concentrate in the 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, and most of the minerals on the planet are hidden underground, so it is still necessary to rely on another simple technology - planet impact!

Dropping a heavy object from high in the sky, hitting the planet quickly, and then analyzing the dust raised can reveal the exact composition of the rock and soil.

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

The planet theoretically lacks metals, only these two.

"The temperature difference on the surface of the planet is too great for moisture on the surface...... So water resources, most likely, are hidden deeper on the surface, in the form of ice cubes. We have found large quantities of ice ore at the north and south poles of the planet. However, the north and south poles are too far away from the stopover point of the spacecraft, and the transportation is not convenient enough. ”

"As for organic compounds, they are the top priority of this exploration. Whether it is 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 female host is broadcasting the planetary impact experiment live. Many ordinary people gathered in the central square, waiting for this exciting outcome.

Satellite 1 is similar to the Moon, with a theoretical small amount of organic matter present. However, if it is not enriched on a large scale, it will be too difficult for human beings to develop, and the economic value will be greatly reduced.

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

Seeing the satellite gradually fly away, Zhang Yuan was a little nervous in his heart: "It should be no problem, right?" ”

A nearby scientist said: "It's hard to say, if we can't find these two sources for a long time, our development will slow down a lot......

"It's even more troublesome to change planets."

The other planets have their own advantages and disadvantages, either they are too close to the stars, or they lack certain elements, or the geological activity is very intense, and there are still volcanic eruptions and earthquakes.

In addition, these artificial satellites are brought from the earth, and once they are launched, it will be extremely difficult to recycle them. At that time, there will be no artificial satellites, and the exploration of other planets can only rely on manual exploration, and the efficiency will be greatly reduced.

"The movement of the mothership also consumes a lot of fuel. Alas, it's better to do it right the first time......"

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

As the experiment progressed, the narrator next door began to speak faster: "Audience friends...... As you can see, the satellite is already approaching the first target area. ”

"According to experts' calculations, this was a supervolcano billions of years ago. Volcanic eruptions are known to exhum large amounts of material, which can also be accompanied by organic matter and sulfur-containing compounds...... It was a very good location to choose from......"

"The experiment has begun!"

In the screen, an iron ball is suddenly ejected from the satellite, and after a long free fall, the speed of the iron ball is getting faster and faster......

In an instant, the iron ball hit the ground with a bang, and because there was no deceleration of air, its energy was comparable to that of a high-explosive bomb, enough to kick up huge clouds of dust.

Of course, no sound could be heard in the vacuum, it was just Zhang Yuan making up the whole process in his brain.

"Okay, ladies and gentlemen, all we need is to wait patiently for a few hours, and our scientists will use the spectrum to analyze the specific composition of these dusts......"

This seemingly boring experiment was repeated sixteen times.

No matter how experienced the commentator is, no matter how much he mobilizes his emotions, the melon-eating crowd in the hall is still drowsy, and most of them have left unconsciously.

In fact, many scientific investigations are very boring, not as passionate as imagined. What ordinary people need is nothing more than an outcome.

But in Earthage's central control room, many researchers were busy, their brows furrowed and furrowed. The results of the first few experiments were not very good......

Time passed slowly, and it was not until 3 p.m. that an abundance of thiophene, aromatic and aliphatic organic matter was found in the dust of Crater 5. The abundance of organic matter in this area is more than 60 times that of ordinary sites, and it is already very valuable for extraction.

Even, underneath the area, there is a large number of cavities caused by the original volcanic eruption, and there is a thick layer of natural ice, with reserves of about 120 million tons. The amount of this water resource is not too much, only equivalent to the water of 10 West Lakes, but compared to the less than 3 million tons of water stored by the Earth Age itself, it is directly 40 times more than that!

For the current human race, it is already a huge amount of water resources!

When the news came, there was a small cheer in the conference room.

"I didn't expect to find two important substances at once." Captain Zhao's face was full of joy: "It proves that our worries are unnecessary, the planet is so big, how can there be no existence of these resources......"

Over the next few days, the robots were lowered from the mothership to investigate the geology of Crater 5 and collect geotechnical samples from various areas, which were then transported back to the mothership by rope.

More than a thousand biologists, as well as doctors, were summoned to work through the night to be on the safe side. The specimens were carefully cut and tried to confirm that there were no living organisms inside. There is a living planet next door, and microbial contamination is not out of the question.

There are many specimens that need to be tested, scattered in various locations of 100 square kilometers, totaling tens of thousands.

But no one felt that it was hard, and many people were like being beaten to death.

Fortunately, there are none, no possible life forms...... This includes carbon-based life, or imaginary silicon-based life!

After this conclusion, everyone cheered quietly again, and the last danger point was eliminated.

The main base for the development of a new civilization has undoubtedly emerged.

"Today is undoubtedly an exciting day. Starting today, we have found our own colonial base. ”

"A hundred years from now, perhaps our technology will catch up with the civilization of the earth...... We'll also be launching our own deep-space colony ship to start the real seeding program! But there is no doubt that all origins start today. ”

"Let's cheer for this day!"

Zhang Yuan saw his colleagues discussing feverishly, and he was also in a high mood and applauded. I don't know why, he always has a faint sense of depression in his heart, and the direction of that depression comes from......

Living planet next door?
