"Comfortable!"

Li Peng took a beautiful bath at the outpost base, and being able to take a bath on the far side of the moon like on Earth is definitely a luxury at present.

About two hours later, Li Peng was repairing at the outpost base for a while, and the transport truck was already ready to leave with 105 cubes of ice, with a total capacity of 52.5 tons.

Accompanying Li Peng was Liu Yiming, who had already completed the handover of the work here, and another half-year period had passed, and this time both of them had to return to Earth.

Five days later, the spacecraft arrived at the Mendeleev crater base once again loaded with thousands of tons of supplies.

This time, Tianqing Technology Group shipped a large number of siege equipment suitable for working on the moon from the earth, in addition to bringing refining and separation equipment, which are needed to build a lunar industrial base by themselves, and also to collect helium three resources for the United States, and the money has already been sent to Tianqing Technology.

As a cross-planetary technology group positioned by Gu Cheng, Tianqing's reputation is leveraged.

After all the goods carried over this time were unloaded, Li Peng, Liu Yiming and other 68 people boarded the Tianjian spacecraft, and this time there were also 89 people, of which 12 people returned to the moon for the second time, and the rest were on the moon for the first time, and they were as excited as Li Peng and their first batch of visitors.

"The next time I come over, it's going to be a different look." Li Peng, who boarded the spaceship, looked back at the main base, witnessing its scale from scratch to the present, and he was also full of emotion, but more because he was extremely proud to participate in it.

This is the supreme honor of a human pioneer.

"Next time, I guess there will be a chance to do a new spacecraft to the moon." Liu Yiming said with a smile, they had long known that the company was stepping up the manufacture of the second Sky Blade spaceship, thanks to the third brother and other countries paying for it.

Twenty minutes later, the spacecraft lifted off again, carrying 68 crew members who had been working on the far side of the moon for nearly six months.

……

During the return of the Tianjian spacecraft, Venus welcomed visitors to the earth again after many years, and Tianqing Technology Group carried out the first low-key probe to Venus at the beginning of this year.

This incident did not attract much attention in the public eye, because the attention of the moon is definitely the focus of space exploration nowadays, especially after the third brother landed on the moon this year, bringing the joyful atmosphere to the far side of the moon.

As for the planet Venus, as early as the last century, after a small amount of exploration in the space hegemony stage of the United States and the Soviet Union, the world's major space powers were not interested in this planet.

Because of the harsh environment and high temperature of Venus, the cost of exploring this planet has soared, and the probes launched in the early years can only work normally for dozens of minutes before they break. The Soviet Union launched several probes one after another and successfully soft-landed on the surface of the planet, and like the previous probes, the equipment failed soon after.

However, the general public did not pay much attention to this incident, but ESA, NASA, Roscosmos and some astronomical institutions paid considerable attention to it, especially some scholars who are keen on Venus research.

As a technology giant that has entered commercial space exploration on a large scale, the normal logic should not be like this, even if it explores extraterrestrial planets, shouldn't it be Mars?

The purgatory-like world of Venus, in describing the horror of this planet, it is difficult not to use some extremely exaggerated adjectives, what is the most terrible planet that people can imagine in their minds, maybe this planet is worse than it, such a planetary world has no commercial development value even if it is poked out.

If the outside world knew about Gu Cheng's "Star Plan", they might not think so.

……

Shangdu, Tianqing Industrial Center, Extraterrestrial Detection and Control Center.

"Mr. Gu!"

"Mr. Gu is good!"

Gu Cheng, who was dressed in simple clothes, came to this control center, and the staff he met along the way greeted him one after another when they saw him.

"How's it going?"

As soon as Gu Cheng arrived, the person in charge of the Venus exploration program had already walked towards him, and immediately responded: "Fortunately, the 'Tianxing Express' has successfully achieved a soft landing yesterday, but even if a large number of the most advanced new materials such as carbonylene alloy are used, the corrosion and destructive power of the probe is already amazing, and I am afraid that it will only last for about half a month before it will lose contact." ”

"Half a month...... Gu Cheng thought about it and couldn't help but nodded, adding: "It's enough, what I'm most concerned about is how much water vapor there is in the composition of the planet's atmosphere, and the information of the Russians is still unreliable." ”

Before that, the most detailed data on this planet in the world was probably the Russians, after all, during the space hegemony between the United States and the Soviet Union in the last century, the former Soviet Union had several explorations of Venus.

Gu Cheng is indeed most concerned about the water source on Venus, there is definitely no liquid water on this planet at present, the atmosphere is rich, and there is no landform on the surface of the earth at all in outer space.

Nowadays, human beings have deepened their space exploration, and have increasingly recognized that all major planets in the solar system have common water source problems, not to mention that there are water sources on the moon, and even Mercury, which is closest to the sun, has meteorite impact craters in its polar regions that also exist in permanent constant shade areas.

Needless to say, Venus definitely has a water source, but it doesn't exist in liquid form on this planet.

"The probe made a soft landing yesterday, and we have obtained a lot of data on Venus, and the information obtained on this day alone is several times richer than all the data obtained by mankind in previous exploration of Venus." The head of the program was quick to speak.

Gu Cheng immediately followed him to the console, and the other party called up the data.

"The latest data shows that more than 90% of Venus's atmosphere is still made up of carbon dioxide, which is extremely dense. Among them, nitrogen only accounts for about 4.12% of Venus's atmosphere, but it is about 20% more than the combined nitrogen in the Earth's atmosphere. At the top of the atmosphere, there are clouds of sulfuric acid, which have a strong ability to reflect light, which is how the bright light of Venus comes from. ”

"Secondly, the atmosphere below is so dense that less than 3% of the sunlight reaches the surface, and the difference between day and night is basically not felt, which is a picture of the probe wearing back."

After speaking, the person in charge called up the pictures, and while Gu Cheng looked at them one by one, he continued: "We have deduced it with a supercomputer with the data we have obtained so far, and it has been preliminarily shown that in the early days of the formation of the solar system, the water on Venus was more abundant than that on Earth. At that time, the Sun was different from today, Venus was still in the habitable zone, and there were oceans of liquid water on the planet's surface. But over time, the habitable zone shifted outward, and when Venus reached the inner edge of the habitable zone, the situation began to take a sharp turn. ”

At this moment, Luo Sheng looked at the dynamic simulation demonstration image he called up.

"As the temperature rises, the ocean evaporates, and a large amount of water vapor enters the atmosphere, and the water vapor has a strong ability to retain heat, resulting in a further increase in surface temperature, which in turn exacerbates the evaporation of seawater, more water vapor enters the atmosphere, and more heat is trapped on the planet and cannot escape, so the disgusting cycle eventually becomes a runaway greenhouse and enters an irreversible trend."

"As all the water evaporates into the atmosphere, the carbon on the planet loses its barrier, and over time, the water vapor in the atmosphere is exposed to enough sunlight, and the charged particles of the solar wind continue to electrolyze the water, breaking it down into hydrogen and oxygen. Hydrogen escapes into space, and oxygen combines with carbon to form carbon dioxide, which eventually replaces water vapor as the dominant component of the atmosphere. ”

It is worth mentioning that as the sun continues to expand, the habitable zone will move further outward, and sooner or later the earth will reach the inner edge of the habitable zone. At that time, under the condition of natural evolution, the current Venus will be a portrayal of the Earth in the future.

However, it is still too far away for humanity.

"How much water is left? Have you come up with reliable results? Gu Cheng immediately asked, he is a pragmatist, how much water is still on Venus, which has a crucial impact on the future colonization of this planet.

Without water, the colonization of Venus will be greatly delayed, so you can only go to distant Saturn to carry water sources, even if the technology tree is fully opened, it will not have much effect without half a century.

Hearing this, the person in charge of the Venus exploration program replied: "At present, the analysis of the enrichment of water vapor in the atmospheric composition of Venus, preliminary data show that it is about 207.9 million cubic kilometers of liquid water. ”

Hearing this data, Gu Cheng couldn't help but be stunned for a while, and said, "So much? There are still 200 million volumes...... It seems that the early stages of water on Venus are not ordinary. ”

In other words, the water resources in the rich atmosphere of Venus are equivalent to about 15% of the earth, and the total water volume of the earth is about 1.386 billion cubic kilometers, and 1 cubic kilometer of water weighs 1 billion tons, which is equivalent to a large water ball of 1,384 kilometers if the water on the earth is gathered together.

Gu Cheng, who looked at the data information, couldn't help but fold his arms and said to himself: "About 15%, it is beyond my expectation that there can be so many, enough is enough, completely enough." ”

Although the earth only accounts for about 15% of the total water on the earth, don't forget that 96.5% of the earth's current water sources are in the ocean, and only about 3% of the freshwater resources are located, and about 70% of this freshwater resources are located in Antarctica.

In Gu Cheng's eyes, the 200 million cubic kilometers of water resources on Venus are not only a lot, but incomparably abundant.

In other words, after the completion of the super-giant light screen device on the Lagrange point of Venus, Gu Cheng can intervene in the movement of the Venusian atmosphere, so as to easily mobilize the distribution of these 200 million cubic meters of water in the form of precipitation or evaporation on a global scale.
