From a subjective point of view, many first-generation elderly people prefer the blue planet; but from an industrial point of view, the last man 4 defeated the royal woman by an overwhelming margin.

In the face of this result, Yu Yifeng's heart is slightly more complicated.But he had to admit that “Dongfu 4” was a better choice.

For the current science and technology, low gravity, cold environment, is more acceptable than complex microbial environments.

“Humans have grown up.”

He suddenly had such an emotion: not loving the civilization of the mother star, can go further...

Humans have chosen the cold planet as its main base, rather than the planet of life, which is actually caused by a qualitative change in science and technology.At present, humans can survive on almost any planet, but it is a difficult or easy question.

The result of the vote came out, and sure enough, the doctor 4 was elected with more than 80% of the votes.

After the selection of the main base, various amendments were made to the details.

The Ayu 4 is about 2.3 astronomical units from the star, with an average density of about 3.6 grams per cubic meter, and in theory, such a planet can find any resource that humans need.

And with the size of a planet, enough for humans to eat...

In these 360 million kilometers away, there is also a gaseous planet with 1.44 times the mass of Jupiter, which is "Further Five".Because of its huge gravity, it has a small impact on the rotation of the yufu 4.

Astronomers are very interested in this big guy and focus on it.

The "Doufu 5" is spinning at high speed, and it can rotate for a week in about nine hours, and various turbulences and vortices appear on the surface of the planet, forming a storm turbulence large and small.

This turbulence is simply the difference between the sea and a glass of water compared to a tornado on Earth.

If you choose "Yufu 4" as the main base, you can observe the nearest distance and use "Yufu 5".

For existing technologies, there should not be much danger as long as people do not die on their own.

"The Ayu 5 has at least 80 satellites, and we can also look for a larger one and establish a sub-base as a nuclear fuel collection base."In this way, there is almost unlimited energy...” Astronomer Professor Thomson suggests.

Because the upper atmosphere of the gaseous planet contains 87% hydrogen, 12% helium, and a small amount of methane, water and other gases.

The most important thing is, of course, the " helium" element!

Helium, as an inert element, is usually present in a gaseous manner.This element is very stable, even after high temperature ionization, the chemical properties are not active, so industrial use is very wide.

The application of high-energy plasma is the cornerstone of the current development of electricians and an important distinction from low-level industries.

Helium is an important medium for the ion industry.Helium gas and hydrogenation, after high temperature ionization, can be used to smelt metal, ultra-high purity is difficult to match the ordinary smelting method; helium ions can also act as a magnetic fluid generator power generation medium, because of the inactive chemical properties, there is no particularly large corrosion to the machine, so that the maintenance cost is greatly reduced.

But on ordinary planets, the mining of helium is too troublesome, even because of its small atomic weight, it has become a relatively rare element in the earth-like planet.

This is because the ordinary planet's own gravity is too small, helium escapes on a large scale, so the reserves are generally not high, and only a small amount of mash can be extracted in natural gas.

“We can get a lot of helium from this gas giant.Helium-3 can be separated as nuclear fuel, and helium-4 is an ordinary industrial material.A gas planet, a steady stream of resources, and the distance is relatively close!"

“Building a base, no problem!”

Seeing the ambitious discussion of the people, Yu Yi Feng was full of joy.

The yupod star is really a feng shui treasure, and the original solar system is almost the same, safe, stable, rich in resources, and even an Earth-like planet exists for people to explore and play.

The “stower” is really good.

This time, humans must pull out more and more ships!

"Yes, we must also provide some cover for the deep space number to prevent the possible discovery of the 'Obitual 2' indigenous people.Do you all have a solution to this problem?”

"Because this star was found by the sower civilization to help us find, for the time being, we adopt a policy of non-interference in the possible indigenous civilization, and look carefully and then ... what do you think?"Yu Feng suddenly thought of a problem.

People thought about it, and there wasn’t much opposition.

How to hide such a large ship?

“This problem ... I think it is possible to use a material that is visually invisible and attached to the surface of the Deep Space.”A materials scientist named Wilf stood up and said.

"On the one hand, we will stop at the doctor 4, not too close, there is a gap between the two planets 3 ... 1.3 astronomical units apart, but also a long distance, if we keep the radio silent, the lower civilization may not be able to find."

"Second, this visual invisible material can deflect light at an angle and reduce the possibility of being found..."

While speaking, Wilf debugged a video on the screen.

Several young people were demonstrating with a piece of transparent fabric, and they covered the transparent fabric on their bodies, and the whole body really disappeared.

Move the cloth away and the body reappears.

"It's amazing, it can be said to be a cloak of invisibility."A scientist in the surrounding area laughed, “These young people made it out, didn’t they?”It's funny."

Wilf nodded and smiled and said, "In fact, the principle is very simple, that is, to deflect the surrounding light, but can only maintain visual invisibility at a few angles, including visible light, infrared, microwave, etc. ... is enough?" 」

After this problem was solved, there were basically no too many details, and finally Yu Feng patted the board: "So be it, after the maintenance of this spacecraft, immediately set off the doctor 4.Industry problems, please be prepared first...”

“Disappearance!”

Time passed, a month of time passed immediately, and the speed of the deep space was getting lower and lower.

As the spacecraft passed the huge gas planet of the "Doufu 5", it clearly observed a huge red spot, which is very similar to the red spot on Jupiter.

This is the first time humans have observed this astronomical phenomenon so closely.

The maximum speed of the Great Red Spot, up to 42,000 kilometers per hour, is a complex to extreme anticyclone storm, from the perspective of a large astronomical telescope, you can also see the thick lightning jump inside, drawing a fierce power grid.

These super lightning, power up to hundreds of billions of kilowatts, a lightning energy, equivalent to a small nuclear bomb!

The largest large red spot, the diameter of about 2.4 Earth, the airflow contains a large amount of red phosphide, so it is a dark brown color.

There is a very small particle in the central part of the Great Red Spot, which is the core of the Great Red Spot, which is about 600 kilometers in size.

It is very strange that this core remains motionless in the surrounding anti-clockwise whirlpool movement, and a magical area of calm emerges.

"The wind is calm in the chaos, I really want to run to the core to see..." Yu Yifeng looked at the core of the Great Red Spot and said with some sigh.

A peripheral scientist shook his head and a smile on his face: “... this is an extremely complex turbulence, caused by the rotation of the planet and its gravity.”Perhaps our calculations have reached their extremes, and mathematics has come a long way before we can accurately simulate the next minute.”

Deep Space has passed this gaseous planet and is about to reach its destination...

More and more people at the observatory also broke out cheering from time to time.

Happy, really too happy, the vast long march, people finally reached the next foothold.

Darkness is not the most feared thing in the universe, and people have become accustomed to it.

This dark planet will be a new beginning, carrying new hope.
