Deep Space Fleet

When I entered the meeting room, I found that many experts present were very happy, and the discussion was very warm. Zhang Yuan quickly found a seat and sat down.

"Everyone please don't be impatient! In 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 counted a huge number of satellites, a total of more than ten There are planets to choose from, but we must find the best and most suitable for development! "

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

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

"We have a long way to go!"

成员 All the members in the meeting room rubbed their hands and a heated discussion sounded.ァ 新 ヤ ~ ⑧ ~ 1 ~ 中文 网 ωωω.χ ~ ⒏ ~ 1zщ.còм

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

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

中央 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 gravity is small, the 6 planets are distributed closer to the star, which is a bit like a solar system with a smaller size.

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

The remaining 4 planets are all terrestrial planets.

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

Inner galaxies are too hot, making it difficult for smaller molecules such as water and methane to aggregate. Therefore, the areas near the stars can only be formed by high-melting substances, such as iron, nickel, aluminum, and stone silicates.

The Jupiter-like planets formed farther away from the freezing line, and the water resources on these planets are anomalous. Because the smaller atomic elements in the universe occupy the vast majority, these Jupiter-like planets can often grow large enough. When the mass grows large enough, they can capture the lightest and most abundant elements of hydrogen and helium, making the mass even greater.

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

I discussed for a few minutes like this, and soon, an astronomer stood up and said, "Please, listen to me first!"

The meeting room gradually quieted down.

如果 "If you choose a satellite of a gaseous planet as your landing point, let's say ... this one."

A huge ice hockey puck is displayed on the screen, with a diameter of about 3,000 kilometers, which is similar to Europa.

Um ... "We can easily get more nuclear fuel and water. Just like Europa's industrial base in our solar system ..."

"At present, after a series of decelerations of the spacecraft, the fuel reserve in the warehouse is not sufficient, which is already lower than 8% of the reserve line ..."

"The quality of the Earth Age is too great. Every time the mothership is moved, it will cause a huge consumption of fuel. So I recommend that the first site selection must be selected."

当然 "Of course, if the main base is selected, these nuclear fuels can still be used for about 3,000 years at the current level of power consumption."

Zhang Yuan frowned.

The number of 3,000 years may sound exaggerated, but only if current energy consumption levels are met.

With the rapid development of industry, the use of electricity will definitely increase exponentially, and these nuclear fuels will soon become insufficient. For example, the energy consumed by smelting metals and industrial production is huge, and the increase in population will also consume more energy. At present, it is only the minimum standard of living.

I saw the astronomer continue: "If you rely on a Jupiter-like planet to serve as a nuclear fuel depot, of course, you don't have to worry about energy."

但是 "However, the choice of Jupiter-like satellites as landing sites, due to the formation of these planets, may be lacking some heavy atomic minerals, such as scarce metals, such as thorium, yttrium and lanthanides."

缺少 "The absence of these elements will cause a huge obstacle to the development of industry. We can never dig deep into the core of the earth, whether at the technical or economic level."

Ye Kaifu, a engineer sitting next to him, tapped on the table with his finger, thinking about the gains and losses. He whispered, "I still prefer resources that are more accessible than energy sources that are more accessible."

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

"I think so too ... energy, only economic and cheap is the most suitable." Zhang Yuan nodded.

I saw the scientist on stage continue: "The second choice is the two innermost planets. Especially the one closest to the star, which is called a metal planet, is not excessive!"

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

This planet also has shortcomings. It has relatively few water resources, lacks organic matter, and the existence of uranium ore is another matter.

"... I have to say that the star in the center is a variable star, whose brightness and electromagnetic radiation are unstable, and flare bursts from time to time. The revolution period of this planet is very short. , The economic losses caused by stellar flares must be taken into account ... "

These are difficult points.

Zhang Yuan frowned. When the star broke out, as long as the defense measures were well done, there was not much problem ~ www.readwn.com ~ The most troublesome is that all kinds of remote communication will be interrupted immediately. The loss can be significant if communication is interrupted by an important task.

"As for the two planets that seem to have a lot of water resources and have the atmosphere, which are located in the habitable zone, we are temporarily out of our consideration."

但是 "But there is a third option, we can consider a satellite of Glizer 581g."

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

A potty planet reappeared on the screen.

The members of the scientific council are more sane people, although the two planets have a large amount of liquid water, it looks beautiful, suitable for human survival. Even one of them, 581g, is an enlarged version of the twins from a certain perspective!

Many people are already on the Internet, cheering for wanting to travel to aliens. First https: // https: //

But ...

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

Also, the planet's mass is 3.1 times that of the earth, and the atmospheric pressure is about 1.7 times that of the earth. At this atmospheric pressure, humans will feel very uncomfortable and must wear a spacesuit at all times to ensure normal survival.

That's why, since there is no way to breathe the surface air freely, we still have to carry various survival equipment, it is better to land on a non-atmosphere, easy to develop planet.
