When he walked into the meeting room, he found that many experts present were very happy, and the atmosphere of the discussion was very enthusiastic. Zhang Yuan quickly found a seat and sat down.

"Everyone, please be calm! The most important thing is to choose a planet suitable for development as our main development base... There are currently six planets observed, and counting the huge number of satellites, there are more than ten planets in total. There are several planets to choose from, but we must find the best and most suitable one for development!"

In the large conference room, Captain Zhao said solemnly, but the excitement in his tone was hard to conceal.

"...Everyone, don't take it lightly. Next, whether it is economic development, population growth, industrial development, or the promulgation of various policies..."

"We still have a long way to go!"

All the members in the conference room were gearing up, and there was a lively discussion.

Various policies, including economic policy, cultural policy, social welfare, work plan, etc., have been discussed for a long time and basically completed. Anyway, when the time comes, it will be fine to promulgate step by step.

The most important thing now is to choose the planet, the most important step.

The mass of this central star is only 0.31 times that of the sun, the surface temperature is about 3200 degrees Celsius, and the light intensity is only 1.3% of the sun. Because the star's gravitational force is small, the distribution of the six planets is closer to the star, which is a bit like a solar system that has shrunk down by one size.

According to astronomical data, the two outermost planets are Jupiter-like planets, that is, gaseous planets. Their mass is relatively large, and there are several satellites with thick ice layers around them.

The remaining 4 planets are all terrestrial planets.

The main reason for the formation of such a structure similar to the solar system is the "nebula theory".

The inner galaxies are too hot for smaller molecules such as water and methane to gather. Therefore, the region close to the star can only be formed by substances with high melting points, such as iron, nickel, aluminum and stone-like silicates.

The Jupiter-like planets formed farther beyond the freeze line, and the water resources on these planets are abnormally abundant. Since elements with smaller atomic weights in the universe occupy the vast majority, the masses of these Jupiter-like planets can often grow large enough. When the mass grows large enough, they can trap hydrogen and helium, the lightest and most abundant elements, making the mass even bigger.

Essentially, a Jupiter-like planet has a rocky core at its center, but its atmosphere is thick enough to hide the innermost core.

After a few minutes of discussion like this, an astronomer stood up and said, "Everyone, please listen to me first!"

The meeting room gradually fell silent.

"If you choose a satellite of a gaseous planet as the landing point, for example... this satellite."

The screen displayed a huge ice ball with pits and holes, about three thousand kilometers in diameter, somewhat similar to Europa.

"...we could easily get more nuclear fuel and water. Just like our solar system's industrial base on Europa..."

"Currently, after a series of decelerations, the fuel reserve in the warehouse is not sufficient, and it is already below 8% of the reserve line..."

"The mass of the Earth Age is too great. Every time the mothership is moved, it will cause a huge consumption of fuel. Therefore, I suggest that the first base location must be chosen well."

"Of course, if the main base is selected, according to the current power consumption level, these nuclear fuels can still be used for about three thousand years."

Zhang Yuan frowned.

The figure of three thousand years sounds exaggerated, but the prerequisite is the current level of energy consumption.

With the rapid development of industry, the amount of electricity used will surely increase exponentially, and these nuclear fuels will soon be insufficient. Metal smelting and industrial production consume a huge amount of energy, and the increase in population will consume even more energy, which is currently only the minimum standard of survival.

The astronomer continued: "If you rely on a Jupiter-like planet as a nuclear fuel depot, of course you don't have to worry about energy issues."

"However, choosing the satellites of Jupiter-like planets as landing sites may lack some minerals with heavier atomic weights due to the formation of these planets, such as scarce metals, such as scandium, yttrium and lanthanides."

"The lack of these elements will cause a very huge obstacle to the development of industry. It is impossible for us to dig deep into the earth's core, whether it is technically or economically, it is impossible to do so."

Engineer Ye Kaifu, who was sitting by the side, tapped the table with his fingers, thinking about the gains and losses. He whispered: "Compared to energy sources that are easier to obtain, I still prefer resources that are easier to obtain."

"Nuclear fusion is not necessary for energy. Fission energy is also possible...even solar energy! Don't think that nuclear fusion is superior to nuclear fission."

"I think so too... As for energy, only economical and cheap ones are the most suitable." Zhang Yuan nodded.

The scientist on the stage continued: "The second choice is the two planets in the innermost ring. Especially the planet closest to the star, it is not too much to call it a metal planet!"

"We can easily find all the rare metal elements."

However, this planet also has disadvantages. There are relatively few water resources and a lack of organic matter. Whether there is uranium ore is another matter.

"...I have to say that the star in the center is a variable star, its brightness and electromagnetic radiation are unstable, and flares will erupt from time to time. The revolution period of this planet is very short, only 4 days around the entire star, and it is very close to the star , the economic losses caused by stellar flares must be taken into account..."

These are all difficult points.

Zhang Yuan frowned. When the stars erupted, as long as the defense measures were done well, there would be no major problems. The most troublesome thing was that all kinds of long-distance communication would be interrupted immediately. If the communication is interrupted while performing some important task, the loss may be great.

"...As for the two planets that seem to have a lot of water resources, have an atmosphere, and are located in the habitable zone, they are not within our consideration for the time being."

"However, there is a third option, and we can consider a satellite of Gliese 581 g."

"One of the satellites is about the size of the moon... even a little bit bigger!"

A cratered planet appeared on the screen again.

The members of the scientific council are relatively rational people, although the two planets have a lot of liquid water, and the environment looks beautiful and suitable for human survival. Even one of them, that is, 581g, from a certain angle, is simply an enlarged version of the twin of the earth!

Many people are already on the Internet, cheering for their desire to travel to alien planets.

but……

According to the spectral analysis of the atmosphere, the concentration of highly toxic gases mixed in the atmosphere, including hydrogen sulfide and ammonium hydrogen sulfide, is as high as 0.02%! This is enough for a human to eat a pot, and even if it is not poisonous, it smells so bad.

Moreover, the mass of this planet is 3.1 times that of the earth, and the atmospheric pressure is about 1.7 times that of the earth. Under this atmospheric pressure, human beings will feel very uncomfortable, and they must wear spacesuits at any time to ensure normal survival.

So, since there is no way to breathe the surface air freely, you still have to carry various survival equipment, it is better to land on a planet with no atmosphere and easy to develop.
