When I walked into the conference room, I found that many experts here were overjoyed and the discussion was very warm. Zhang Yuan quickly found a seat to sit down.

"Please be careful! The most important thing is to choose a planet that is suitable for development as our main development base... There are currently six planets observed, and including a large number of satellites, there are more than ten planets to choose from, but we must find the best and most suitable for development!"

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

"...Don't take it lightly. Next, whether it is to develop the economy, grow the population, develop industry, or promulgation of various policies..."

"Our mission is still a long way to go!"

All the members in the conference room were ready to go, and a heated discussion sounded.

Various policies, including economic policies, cultural policies, social welfare, work plans, etc., have been discussed for a long time and have basically been completed. Anyway, it will be fine if you promulgate step by step.

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

The mass of this central star is only 0.31 times that of the sun, with a surface temperature of about 3,200 degrees Celsius, and a light intensity of only 1.3% of the sun. Because the star's gravity is small, the distribution of the six planets is closer to the stars, which is a bit like a solar system with a shrinking number 1.

According to astronomical data, the two outermost planets are woody planets, that is, gaseous planets. They have relatively large mass and there are several satellites with thick ice layers around them.

The other four planets are all terrestrial planets.

The main reason why such a structure similar to the solar system was formed is the "nebula theory".

Because internal galaxies are too hot, molecules with smaller mass such as water and methane are difficult to gather. Therefore, areas close to stars can only be formed by high melting points, such as iron, nickel, aluminum and litho-like silicates.

The juicy planets are formed outside the farther freezing line, and the water resources on these planets are abundant and abnormal. Since the smaller atomic elements in the universe account for the vast majority, the mass of these juicy planets can often grow large enough. After the mass grows large enough, they can capture the lightest and richest elements of hydrogen and helium, making the mass bigger.

In essence, there will be a rock core in the center of the woody planet, but its atmosphere is thick enough to cover up the most core thing.

After a few minutes of discussion, a astronomer stood up and spoke, "Everyone, please listen to me first!"

The conference room gradually became quiet.

"If a certain satellite of a gas planet is selected as the landing point, for example... this satellite."

A huge ice hockey with a pothole is displayed on the screen, with a diameter of about 3,000 kilometers, which is a bit similar to Europa."...We can easily obtain more nuclear fuel and water resources. Just like the Europa industrial base in our solar system..."

"At present, after a series of slowing down the spacecraft, the fuel reserves in the warehouse are not sufficient, which is already below 8% of the reserve line..."

"The Earth Age is so mass that every time the mothership is moved, it will cause huge fuel consumption. So I suggest that you must choose the first base location."

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

Zhang Yuan frowned.

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

With the rapid development of industry, the use of electricity will definitely increase exponentially, and these nuclear fuels will soon be insufficient. For example, smelting metals, industrial production consumes huge energy, and the increase in population will also consume more energy. Currently, it is just the lowest standard for survival.

The astronomer continued: "If you rely on a woody planet to act as a nuclear fuel bank, of course you don't have to worry about energy."

"However, selecting a satellite of the Muslim planets as the landing point may lack certain minerals with heavier atomic weight, such as scarce metals, such as scandium, yttrium and lanthanides."

"The lack of these elements will cause a huge obstacle to the development of industry. We can't mine to the depths of the earth's core, and it is impossible to do this at the technical level or economic level."

Engineer Ye Kaifu, who was sitting beside him, tapped the table with his fingers, and was considering the gains and losses. He whispered: "Compared with more easily accessible energy, I still prefer more easily accessible resources."

"The energy does not have to be fusion, fission energy is also possible...even solar energy is OK! Don't think that nuclear fusion is higher than nuclear fission."

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

The scientist on the stage continued: "The second choice is the two innermost planets. Especially the planet closest to the stars, it is not an exaggeration to call it a metal planet!"

“We can easily find all the scarce metal elements.”

But this planet also has its shortcomings, with relatively few water resources and 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. The brightness and electromagnetic radiation are unstable, and flares will burst from time to time. The orbital period of this planet is very short, and it only takes 4 days to circle the entire star and is very close to the star. The economic losses caused by the flares of the star must be taken into account..."

These are all difficulties.

Zhang Yuan frowned. When a star explodes, as long as the defense measures are done well, there is no big problem. The most troublesome thing is that various remote communications will be interrupted immediately. If any important task is being performed, the loss will be great.

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

"But there is a third option, we can consider a satellite from Glitzer 581g."

"One of the satellites is probably the size of the moon... and it's even a little bigger!"

A pothole-filled planet appeared again on the screen.

The members of the Science Council are all more rational people. Although those two planets have a large amount of liquid water, they look beautiful in the environment and are suitable for human survival. Even one of them, 581g, is magnified from a certain perspective, is simply an enlarged twin of the earth!

Many people are already online cheering and want to travel to aliens.

but……

According to the atmospheric spectrum analysis, the concentration of highly toxic gases mixed in the atmosphere, including hydrogen sulfide and sulfur dioxide, is as high as 0.02%! This is enough for humans to eat a pot.

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, humans will feel very uncomfortable and must wear space suits at any time to ensure normal survival.
