2040.

The sun has expanded to near the orbit of Venus.

Venus, which originally had a thick atmosphere, was completely transformed into a bare planet by the close-range solar storm.

Just like Mercury before.

"Zero, when will Venus fall into the sun?"

Lu Yongchang looked at the holographic image in front of his desk and asked softly.

"December 10, 2042, Professor." Lingyan responded to Lu Yongchang's inquiry concisely and concisely.

Lu Yongchang stared blankly at the expanding fireball.

On December 10, 2042, Venus set in the sun.

This is the deadline for humans to leave Mars.

Unlike Mercury, the impact of Venus falling into the sun is extremely huge.

There are two reasons.

On the one hand, Venus is closer to Mars than Mercury.

On the other hand, as the smallest planet in the solar system, Mercury has an average radius of only 2,440 kilometers, while Venus has an average radius of 6,073 kilometers!

This means that when Venus falls into the sun, it will cause a solar storm that doubles in power!

If humans continue to stay on Mars, the outcome can be imagined.

"Zero, where is the Heaven Plan?"

Lu Yongchang was silent for a moment and asked again.

A year ago, after the energy crisis was resolved, Lu Yongchang immediately made the decision and directly launched the Tianting Project.

After the Tianting Project was launched, almost all of Zero's computing power was invested in various factories.

As Lu Yongchang finished speaking, the holographic image in front of him suddenly changed.

The original star map of the solar system disappeared, replaced by a scene outside the Mars spaceport.

I saw starships with a length of 1,500 meters neatly arranged in the deep and dark space.

"Professor, 63.8% of the Heavenly Palace Project has been completed." Zero's voice sounded from the side.

"As of now, 500 [Home] Nebula-class starships have been manufactured."

"The manufacturing progress of 500 [Taotie] Nebula-class material reserve ships is more than halfway completed."

"The production of 250 [Golden Crow] Nebula-class battleships has not yet begun."

"Construction of the new flagship [Earth] has not yet begun."

Lu Yongchang nodded thoughtfully. With the breakthrough in starship manufacturing technology, the original Heavenly Palace plan also made corresponding changes.

The Nebula-class starship is the result of the improvement of the first-level civilization's technology tree.

In other words, these starships contain the pinnacle technology of first-level civilization.

In Lu Yongchang's plan, starships will be divided into nine levels.

The order is nebula level, comet level, asteroid level, satellite level, planet level, star level, white dwarf level, neutron star level, and finally the black hole level starship.

In Lu Yongchang's view, only these starships in the Tianting Plan can be called Nebula-class starships.

In the past, those Luanniao and Xuannv starships could only be regarded as transitional products.

If we insist on counting, perhaps it should be called a satellite-class starship.

"When are all construction projects expected to be completed?" Lu Yongchang asked directly.

Zero's response followed: "It is expected that all construction tasks will be completed by October 2042."

October 2042…

Lu Yongchang frowned.

Humans only have two months to avoid the huge solar storm caused by Venus falling into the sun.

As for the escape plan, Lu Yongchang had already thought of it.

After leaving Mars, the human fleet will head directly towards Jupiter.

By then, 1,250 starships will "hide" on the back side of Jupiter, and then set off to the Kuiper Belt after the solar storm passes.

only……

"Isn't two months too tight?" Lu Yongchang frowned and asked in a low voice.

"Professor, there is enough time." Zero quickly presented a series of calculation and deduction results in front of him.

"According to calculations, we will arrive at the far side of Jupiter one week before Venus sets in the sun."

Hearing this, Lu Yongchang's right eyelid twitched slightly: "I hope so."

The office fell silent again.

"Professor, there is bad news." Zero's voice sounded again.

This familiar tone and voice made Lu Yongchang's right eyelid jump again.

"hiss……"

He gasped sharply.

How long has it been?

This thing is so smart?!

"Tell me." Lu Yongchang put his hand on his forehead and said weakly, "What's going on?"

Zero's tone was very calm: "Professor, our hydrocarbon reserves have dropped to warning levels."

Lu Yongchang couldn't help but be stunned, and then he realized: "Hydrocarbons? How did this stuff drop to the warning level?"

The so-called hydrocarbons are nothing more than various hydrocarbon substances.

Methane, acetylene...

In addition to serving as fuel, these substances can also synthesize various chemical substances, which can be said to be indispensable raw materials for modern industry.

Under normal conditions, under a complete industrial system, this thing will not be scarce at all.

For example, methane can be synthesized by adding hydrogen to carbon dioxide and carbon monoxide.

"The synthesis rate problem." Zero explained softly, "After the Tianting Project was launched, our consumption rate was far greater than the synthesis rate."

"All right."

There was a bit of helplessness in Lu Yongchang's eyes.

These raw materials, which are extremely common on the earth, are now even scarce.

"I'll find a way."

After speaking, Lu Yongchang fell into deep thought.

He subconsciously rapped his knuckles on the desk in front of him, thoughts flashing through his mind one after another.

If we were on Earth, it would be extremely simple to obtain these hydrocarbon materials.

Extracted from fossil fuels, or biogas digesters...

In short, there are countless ways to obtain large amounts of hydrocarbons.

But after leaving the earth, these methods will not work.

There is no such thing as fossil fuel on Mars!

As for the biogas pool...

Now Mars City does not have so much organic waste to produce biogas!

After thinking for a long time, he decided to set his sights on other planets.

"Zero, help me open the star map of the solar system and mark the location of Titan."

The holographic image changes silently.

The relative positions of Mars, Jupiter, Saturn, and Titan were instantly displayed in front of Lu Yongchang.

“Relatively good location.”

The moment he saw the holographic screen, Lu Yongchang's eyes lit up: "Zero, call Fang Xu and the others."

"Next, prepare to land on Titan!"

Titan, also known as Titan.

It is the largest of all the satellites of Saturn and the second largest satellite in the solar system.

What's special about it is that it is the only satellite with a dense atmosphere, and its surface atmospheric pressure is even 1.5 times that of the Earth!

(Io, Europa, Ganymede, Callisto, Enceladus and Triton all have atmospheres, but the atmospheres are extremely thin.)

In addition, the composition of Titan's atmosphere is very peculiar. In addition to 98.44% nitrogen, there are also a large number of different types of hydrocarbons.

According to detection, there are a large number of oceans and lakes composed of hydrocarbons on the surface of Titan, with a surface temperature as low as -179 degrees Celsius!

This is the reason why Lu Yongchang decided to land on Titan.

By then, the collection ship can even draw large amounts of liquid hydrocarbons directly from the methane ocean on Titan's surface!

Convenient and worry-free, it even saves the effort of compressing gas.
Chapter completed!
