Returning to the ground, Zhang Hao quickly convened a high-level meeting of Dayang Group. As for the issue of selling the small spaceships found on the moon base and left behind by the Xuanhuang civilization, it was solved in a few words.

In fact, everyone has long had such an idea of selling spaceships.

With the recent development of space and the great pressure on funding, it's time to 'open source'. Especially now that everyone has cooperation and competition, good things are held in their hands and not let go, which is not conducive to long-term.

However, there has been no consensus on when it will be sold and at what price, but the approximate conditions have already been met.

Now, under this opportunity, everyone quickly finalized the transaction plan: the ship's price is 8.5 billion Lingyuan, which can be paid in installments, but the down payment must be more than 30%;

The price of the spaceship is 8.5 billion spirit stones, which sounds a bit high, but the actual situation is not high - after all, this is left by a high-level civilization, and the smallest spaceship is also more than a hundred meters in diameter, and has a strong transportation capacity, which is extremely valuable in the current situation where space development is just beginning.

Before that, everyone's transportation cost in space was calculated in 'grams'. For example, the cost price of the materials launched from the ground to space by the Ocean Group is as high as 4 yuan per gram - the purchasing power of the currency of the Ocean Group is not small, one yuan can buy five catties of brown rice, which is equivalent to the ration of an ordinary family for three days.

The cost of transportation from the orbit of Tianyuan Star to the moon is as high as 2 yuan/gram if it is transported by rocket. Thinking about industrial construction, it is often calculated according to one million tons, and the transportation cost of 2 yuan/gram is unbearable.

After the spacecraft is activated, the transportation cost between spaces will drop significantly, which can be reduced to 1,000 yuan per ton - mainly because the cost of nuclear fuel for the spacecraft is high, and the maintenance cost of the spacecraft is also high.

In short, as space technology becomes more and more perfect, and as Xuanhuang Group and Hetu World also plan to make a difference in space, it is imperative to purchase spaceships from Dayang Group.

Fortunately, the Ocean Group has long considered this, and Zhang Hao is also very clear: the current situation of Tianyuan Star is different from the earth in the past.

In the past, no extraterrestrial threats were found, so all parties were pulling hard between each other, and there were good things hidden, so they were afraid that their neighbors would know.

But this world is different, everyone is facing a powerful threat, and under this threat, everyone has to do everything possible to develop and become stronger. Cooperation with each other is inevitable, or rather the only option.

But cooperation is cooperation, and brothers have to settle accounts.

Once the ship is decided, everyone moves on to the next meeting: Venus Development!

The discovery of large, high-grade ore on Venus was previously unexpected. Previously, everyone thought more about going to the asteroid belt, that is, the orbit where the Xuanhuang civilization came to the orbit of the planet where the galaxy first resided, and after the planet was broken, a large number of asteroids were left behind.

But the discovery on Venus forced the Ocean Group to change its plans.

Compared to asteroids, Venus is closer and has more resources. And Venus itself is huge, and it can build a huge factory. There was an active, even intense discussion, about this, with the final focus on Venus' biggest problem: the environment.

Zhao Dahe pointed to the picture of Venus and talked eloquently: "The environment of Venus is too harsh, acid rain, high temperature, corrosive atmosphere, strong winds, flashes, sand and dust, etc., will cause great trouble to industry and construction, as well as later maintenance and development.

Venus's gravitational pull is not large, but it is not small. In such harsh conditions, it would be very expensive to launch supplies into space. First of all, the laser launch is afraid that it will not work, and it can only be launched by rockets. At present, our rocket launch technology is far more expensive than laser launch.

In addition, if you want to develop industry on Venus, you need a lot of water. What is temporarily found on Venus is only concentrated sulfuric acid, and the quantity is not much, which cannot meet the needs of industrial development at all. Even the conditions for permanent personnel cannot be met.

To sum up, I think that if you want to develop industry on Venus, you need to draw a question mark for the time being. As it stands, I think asteroid mining is still more advantageous.

Just like planned, by slowing down the asteroid, the asteroid will fly around the moon on its own.

In contrast, even if the materials in the orbit of Venus are sent to Tianyuan Star, the materials will have to be accelerated. And with our current technology, deceleration is obviously simpler. All it takes is a little ordinary gunpowder, and to build a reverse flame canister, it is enough to complete the acceleration. ”

"But...... The acceleration is similar. Is there an essential difference between acceleration and deceleration in space?" a small voice came from the end of the conference room.

"Who!" Zhao Dahe's eyes widened, "Stand up and speak!"

"Stand up, stand up!" a young man stood up from the end of the conference room, six points similar to Huang Mingshan.

"Oh, Huang Mingshan's son? I remember your name is Huang Bo, right?"

"That's a nickname. My name is Venus!"

Zhao Dahe's face was a little unhappy, and the old expert was actually pushed by the hairy boy: "Okay." The Venus is the Venus. Tell me, acceleration or deceleration, which is easier, and why?"

Venus stalked his neck and said: "It's not easier, from a physical point of view, whether it is acceleration or deceleration, the principle of kinetic energy is the same." However, if you put things on the actual problem solving, there is a difference.

Before I say that, I'm going to make a hypothesis first. That is, whether it is asteroid mining, or Venus development, the final product has to be transported to Tianyuan Star, right?"

"That's right!" Zhao Dahe nodded.

A confident smile appeared on Venus's face: "To transfer supplies in space, you must first calculate the orbital speed.

The orbital velocity of Tian Yuan Star is 30 kilometers per second, the orbital speed is 48 kilometers per second, and the orbital speed of asteroids is 15 kilometers per second on average.

The potential energy is calculated according to the gravitational force of the sun, and the gravitational force of the sun at the position of the star is ......"

"Alright, I know what you're going to say. Zhao Dahe interrupted Jin Xing's words, "We have also calculated what you said." If we look at the Sun as the basic point, the movement of Venus towards the Celestial Yuan Star is an increase in altitude, while the movement of an asteroid towards the Celestial Yuan Star is a decrease in altitude.

These things don't actually need to be calculated, they are clear at a glance. Even from a purely physical point of view, it's easier to slow down. Not to mention that the materials on Venus must first get rid of the gravitational pull of Venus. ”

"But if we develop an asteroid, we need to move the entire asteroid, and the effective resource content of the asteroid is less than 2 percent, that is, 98 percent is doing useless work.

In contrast, if we build a factory on Venus, we can purify the resources and send them back. ”

Zhao Dahe stopped talking.

But at this time, another voice came out: "It's too troublesome to build a factory on Venus." If it is just for resources, the resources on the Tian Yuan Star are very abundant and more convenient. The huge Tian Yuan Star is enough for us to fully step into the starry sky civilization!"

Golden Star glared at the other party angrily, and this time it was the young master of the Ocean Group, Zhang Xiaoning, who spoke. Zhang Xiaoning, who is only six years old now, is already fifteen or sixteen years old, and he is even more intelligent. We have now begun to observe the meetings of the Dayang Group.

"Xiao Ning!" Zhang Hao spoke, "Come to me." ”

When Zhang Xiaoning arrived next to Zhang Hao, Zhang Hao knocked on the little guy's door, "Don't speak, don't you hear it." ”

Then Zhang Hao looked at the heated discussion and spoke: "Your discussion is very meaningful, allowing us to understand space and plan the future of Dayang Group in an all-round way. But I also have an idea that brings together all the discussions.

I think our plans could be a little crazier. ”

Crazier?

Everyone looked at Zhang Hao.

Zhang Hao got up, came to the back wall/display screen, pointed to the galaxy map above and said, "We have currently discovered three small ice planets in the asteroid belt. Combined, these three small ice planets are about one-third the volume of the Moon and about one-twenty-fifth the volume of Venus. That's 4% of Venus's volume.

And the water content of these three small planets, according to current observations, should be around 60%.

If you can land three ice planets on Venus, you can make Venus moist, and you can increase the water content of Venus from almost nothing in the past to about 2.4%.

And the water content of Tian Yuan Star is only 1.8%!"

Everyone's eyes widened suddenly, shocked by Zhang Hao's 'crazier' idea.

Zhao Dahe was a little trembling, "Mr. Zhang, this ...... Even if we can pull the ice planet into the orbit of Venus, the impact force between the planets is enough to completely destroy Venus, and even the possibility of disintegration cannot be ruled out. The worst possible scenario is that Venus's orbit will change or even get out of control.

This collision of celestial bodies has temporarily exceeded our computing power. ”

Zhang Hao smiled: "Who said it was going to collide." We're not building a starry cannon, just to test the power of the starry cannon.

When the three ice planets approach Venus, we will attack from the location of the Tianyuan star, and the cannonballs will fly 40 million kilometers or even farther to shatter the ice planets. In this way, Venus uses its gravitational pull to attract fragments of the ice planet. So there will be a meteor shower, a meteor shower with an ice core!

A large amount of cold ice will lower the temperature of Venus.

In addition, if the landing angle of the ice rain is calculated, Venus can be rotated by the continuous bombardment of the ice rain. As long as Venus rotates, its liquid core will produce a magnetic field. Let Venus have the foundation to become a habitable planet.

Then we will be able to set up factories on Venus. ”

Zhao Dahe, Zhang Xinhan, Huang Mingshan and other scientific research elites of Dayang Group looked at Zhang Hao dumbfounded. This plan is really crazy enough.

But if you carefully calculate all the circumstances, the feasibility is even higher!
