From a subjective point of view, many first-generation seniors prefer the blue planet; But from an industrial point of view, Mio 4 defeated Mio 2 by an overwhelming margin.

Faced with this result, Yu Yifeng's heart was slightly complicated. But he had to admit that "Mio 4" was a better choice.

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

"Humanity has grown up."

He suddenly had such a feeling: If you don't love the civilization of the home planet, you can go further......

Human beings have chosen the cold planet as their main base instead of the living planet, in fact, this is caused by qualitative changes in science and technology. At the current level, it is only a matter of difficulty or ease whether humans can survive on almost any planet......

The voting results came out, and sure enough, Mio 4 was elected with more than 80% of the votes.

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

Mio 4 is about 2.3 astronomical units from the star, with an average density of about 3.6 grams per cubic meter, and theoretically, such a planet could find any resources that humanity needs.

And with the size of a planet, it is enough for human beings to eat......

360 million kilometers away, there is also a gaseous planet with a mass of 1.44 times Jupiter, known as "Mio 5". Because of its huge gravitational pull, it has a small effect on the revolution of Mio 4.

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

"Mio 5" is rotating at a high speed, about nine hours to rotate for a circle, all kinds of turbulence and vortices appear on the surface of the planet, forming large and small storm turbulence.

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

If Mio 4 is selected as the main base, you can observe and use Mio 5 at close range.

As far as the existing technology is concerned, as long as people don't die themselves, there shouldn't be too much danger.

"Mio 5 has at least 80 satellites, and we can also look for a larger one and build a sub-base as a nuclear fuel gathering base. In this way, there is almost unlimited energy ......," advises astronomer Professor Thomson.

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

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

Helium, as an inert element, is usually present as a gas. This element is very stable and chemically inactive even after ionization at high temperatures, so it has a wide range of industrial applications.

The application of high-energy plasma is the cornerstone of the current development of electrical engineering, and it is also an important distinction from low-level industries.

Helium is an important medium in the ionic industry. Helium hydrogenation, after ionization at high temperature, can be used to smelt metals, and the ultra-high purity is incomparable with ordinary smelting methods; Helium ions can also be used as a power generation medium for ferrofluid generators, because of their inactive chemical properties, they are not particularly corrosive to the machine, so that the maintenance cost is greatly reduced......

But on ordinary planets, helium mining is too troublesome, and even because of its small atomic weight, it has become a relatively rare element among terrestrial planets.

This is because the gravitational pull of ordinary planets is too small, and helium escapes on a large scale, so the reserves are generally not high, and they can only be mixed and matched in natural gas to extract a small amount.

"We can get a lot of helium from this gas giant. Helium-3 can be separated and used as nuclear fuel, and helium-4 can be used as an ordinary industrial material. A gaseous planet with a steady stream of resources, and it's relatively close! ”

"Build a sub-base, no problem!"

Seeing everyone's ambitious discussion, Yu Yifeng was full of joy.

Yufu Star is really a treasure of feng shui, almost no different from the original solar system, safe, stable, rich in resources, and there is even an earth-like planet for people to explore and play.

The eye of the "sower" is really not bad.

This time, humanity must hold back more and more spaceships!

"By the way, we also need to provide some cover for the Deep Space to prevent it from being discovered by the possible 'Mio 2' natives. Is there a solution to this problem? ”

"Because this star was found by the Sower civilization for us, for the time being, we will adopt a policy of non-interference with the possible indigenous civilizations, and we will observe carefully before we ...... What do you think? Yu Yifeng suddenly thought of a question.

Everyone thought about it, and there were not too many objections.

But how to conceal such a large spaceship?

"This question...... I think we could use a visually invisible material and stick it to the surface of the Deep Space. A materials scientist named Wilf stood up and said.

"On the one hand, we stop at Mio 4 and don't get too close, and there is a Mio 3 in between...... The two planets are separated by 1.3 astronomical units, which is quite a long distance, and if we keep the radio silent, the lower civilizations may not be able to detect it.

"Second, this visually invisible material can deflect light at a certain angle, reducing the possibility of detection......"

As he spoke, Wilf debugged a video on the screen.

Several young people were holding a piece of transparent cloth for demonstration, and they put the transparent cloth on their bodies, and their whole bodies really disappeared.

The fabric is removed and the body reappears.

"It's amazing, it's an invisibility cloak." A nearby scientist laughed: "These young people made it, right?" It's interesting. ”

Wilf nodded and said with a smile: "Actually, the principle is very simple, that is, it deflects the surrounding light, but it can only keep the vision invisible at certain angles, including visible light, infrared, microwave, etc...... Enough is enough, right? ”

After this problem was solved, there were basically no too many details, and finally Yu Yifeng clapped his hands and said: "Then let's do it, after the maintenance of this spacecraft is completed, we will immediately set off for Yufu 4." Industrial problems, please prepare first......"

"Adjournment!"

Time passed, a month passed quickly, and the speed of Deep Space was getting lower and lower.

When the spacecraft passed by the huge gaseous planet "Mio 5", it clearly observed a large red spot, which is very, very similar to the red spot on Jupiter.

This is the first time that such an astronomical phenomenon has been observed at such a close distance.

The Great Red Spot, with a top speed of 42,000 kilometers per hour, is an extremely complex anticyclonic storm, and from the angle of a large astronomical telescope, you can also see the thick lightning jumping inside, drawing a fierce and violent power grid.

These super lightning bolts have a power of up to 100 billion kilowatts, and the energy of a lightning bolt is equivalent to a small nuclear bomb!

The largest one, the Great Red Spot, is about 2.4 Earths in diameter, and contains a large amount of red phosphide in the airflow material, so it has 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, and its size is about 600 kilometers.

Strangely enough, this core remained motionless in the anti-clockwise vortex motion around it, and a magical calm zone appeared.

"The chaos is calm, I really want to run to the core to take a look......" Yu Yifeng looked at the core of the big red spot and said with some sighs.

A nearby scientist shook his head with a smile on his face: "...... This is an extremely complex turbulent motion, caused by the rotation of the planet as well as gravity. Perhaps we have advanced our calculations to the extreme, and the mathematics has advanced greatly, so that we can accurately simulate the state of the next minute. ”

After passing over the gaseous planet, Deep Space is about to reach its destination...... Mio 4!

There were also more and more people at the observatory, and cheers erupted from time to time.

Happy, really happy, the vast Long March, people have finally reached the next foothold.

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

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