Although the excitement is abnormal.

Although Wei Ming has regarded the entire Mars as his own territory.

But he only stayed on Mars for half a day, found 3 coordinates with abundant water sources, dug up 100 kilograms of soil and rocks, and then embarked on a journey back.

Because he's been in space for five days.

If you don't go back quickly, if you delay for too long, some people may panic and worry.

There is no signal on Mars, you can't call home, you can't send messages, and there has been no news for a week, so it's strange that you don't panic in a hurry.

Besides, Mars is so big, it is impossible to run, other institutions do not say that they will send people over, there will be no probes, and large-scale interstellar colonization is even more ridiculous, and it is unlikely that it will be possible in 20 years.

This piece of fat can't escape from Wei Ming's mouth.

……

August 18th.

At 1 a.m.

Villa next summer.

The drop landed smoothly and landed in a drawn white wireframe.

The hatch opens.

Wei Ming, who looked quite tired, fell to the ground, and suddenly stumbled, and returned to the ground after a long time of weightlessness or slight weightlessness, and was quite uncomfortable.

"You're finally back?"

Xu Chuxia trotted to him in a hurry: "Where have you been these days?" The phone can't get through, no one answers the message, I'm going to be worried about you to death! ”

She threw herself into the man's arms and beat him on the chest repeatedly: "Something is going to happen to you, what should I do with the child?" ”

"It's okay, it's okay~"

Wei Ming patted her back and said comfortingly: "It's just a trip to the moon and stars, the journey is a bit far, and it takes a little time, how did you make it like the sky is falling, is it necessary to be so exaggerated?" Do you think I could have an accident? ”

"Moon Star? Mars? ”

The woman collected her tears and said suspiciously: "You said that it is a bit possible to go to the moon star, Mars is so far away, how can it be possible to run back and forth so quickly?" ”

"That's slow."

Wei Ming shook his head and said: "I regret making such a big guy, the maximum acceleration can't exceed 10G, if you can shrink a few numbers, you can run back and forth in a day; A little more aggressive, put on a sealed armor, and even if the oxygen backpack only lasts for 5 hours, I can run back and forth during this time! ”

Five hours?

The woman stood still for a moment, far beyond her imagination.

"Wait a minute, I'll bring that industrial camera."

Thinking of something, Wei Ming returned to the Water Drop and took out the industrial high-definition camera.

Home cinema hall on the second floor of the villa.

Wei Ming imported the picture data from the industrial camera into the laser projector and played out the pictures one by one.

These high-definition pictures are Wei Ming's travel harvest in the past few days.

Oh, and he also brought about 100 kilograms of rocks and soil from Mars, took out a stone the size of an egg, put it in the woman's hand, and said, "This is a rock on Mars, which is a gift I brought to you." ”

Xu Chuxia took the stone and put it in front of him to observe and rub it.

On the other hand, I looked at the pictures one by one and found that the man did not fool her, but really went to the moon and Mars.

Previous fears have been dispelled

But the anger in my heart not only did not dissipate, but became even more dissatisfied.

"Since there's so much space in your Water Drop, why don't you take me with you? Isn't it a big deal to bring your son with you? Such a fun thing, you always take care of yourself. She said as she glared at the man.

"The space environment is weightless, how can you feed and change diapers in such an environment?"

Wei Ming said: "Dong Dongbao is so active, what if you accidentally break the equipment inside, if you don't make it happen, the whole family will become space junk, this kind of thing can't be willful." ”

"When my two sons are asleep, can you take me to space for a while?"

Xu Chuxia said: "It's okay to stay for half an hour or an hour, your photos are not good-looking, and your photography skills are too poor, I want to go to space to take them myself." ”

"Okay, okay!"

Wei Ming walked to the bedroom: "I'll take you up tomorrow to have a good time, I'm so sleepy now, go back to my room to sleep." He yawned and lay down on the bed, and soon fell asleep.

Xu Chuxia stayed in the home theater hall and didn't leave, although she didn't dare to compliment Wei Ming's photography skills, she still looked at those photos several times, and her eyes were full of yearning and curiosity.

Especially on Mars, the selfie of the man and the Water Drop was compared to a scissor hand, which was so funny that it made people laugh.

……

The next afternoon.

Black Hole Cosmos Development Corporation.

Wei Ming took the 100 kilograms of Martian rocks and soil to the elemental analysis laboratory, found Bai Jinglun, the person in charge of the laboratory, and asked them to study the composition of these substances and count the proportions of each element.

As for the elements in it and how much it contains, Wei Ming scanned it with Xiao Hei, and he basically knew it in his heart, and he didn't need any instruments to detect it.

He brought these soil rocks to give them some quizzes to test their professional abilities.

"Oxygen content 50%, silicon content 18%, iron content 15%, aluminum content 4%, magnesium content 3%, calcium 4.3%, sulfur 3%, titanium ......"

After a brief test.

Bai Jinglun looked at Wei Ming and asked, "Mr. Wei, where did you bring this soil from?" The composition of each element is very similar to that of Martian red soil, unless it is artificially mixed, this kind of soil cannot exist on the blue star, and I even mistakenly think that this is the soil brought from Mars. ”

"Ahem~"

Wei Ming coughed twice and said: "Don't ask how it came from, let me ask you, is the value of this soil high, can it be used as a raw material to refine a variety of high-value resources?" ”

"High! Its value is certainly high. ”

Bai Jinglun said: "Its iron and aluminum content adds up to 19%, and the grade is not very high, but in the industrial field, it already has the value of selection and smelting, and has a certain profit margin." The other 1.5% titanium content is definitely high-grade perovskite, and the refining value is very high! The soil on the surface of Mars contains tens of billions of tons of titanium, and the mineable reserves are more than ten times that of Blue Star, and if large-scale mining and refining are carried out, a large amount of cheap titanium can be obtained. ”

"You mean, the most ordinary soil on Mars has a certain economic value?"

"That's right!"

Bai Jinglun nodded: "I think the value of Martian soil will not be worse than that of medium and high-grade iron ore." ”

Of course, the greatest value of Mars is not how many metal minerals such as iron, titanium, and aluminum it has.

However, it is rich in light elements, and the air contains a large amount of carbon dioxide and 2.7% nitrogen, so it is theoretically possible to directly use the Martian soil to grow crops, as long as it finds abundant water resources, it can produce a lot of food.

It may not be impossible to open up a new living space for mankind.

Wei Ming nodded.

Now he basically has a plan in his mind, and he has a general idea and plan in his mind.
