Wandering Spaceship in Deep Space Chapter 199: Planet selection
When I walked into the conference room, I found that many experts in the room were pleased. The atmosphere of the discussion was very enthusiastic, and Zhang Yuan quickly found a seat to sit down.
"Everyone, please stay calm! The most important thing is to choose a suitable planet as our main development base... There are currently six planets observed, including a huge number of satellites, a total of There are more than ten 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 could not be concealed.
"...Don’t take it lightly, everyone. Then, whether it is economic development, population growth, industry development, and the promulgation of various policies..."
"Our task is still a long way to go!"
All the members in the meeting room were gearing up, and there was a lively discussion.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 basically been completed. Anyway, when the time comes, it will be promulgated 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 that of the sun. Because the stellar gravitational force is small, the distribution of the six planets is closer to the star, a bit like a solar system that has shrunk down.
According to astronomical data, the two outermost planets are Jupiter-like planets, which are gaseous planets. They have relatively large masses, 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".
Because the inner galaxies are too hot, it is difficult for molecules with smaller masses such as water and methane to gather. Therefore, the area close to the star can only be formed by high melting point materials, such as iron, nickel, aluminum, and stone silicate.
While the Jupiter-like planets are formed farther away from the freezing line, the water resources on these planets are abnormally abundant. Since elements with relatively small atomic weights occupy the vast majority in the universe, the masses of these Jupiter-like planets can often grow large enough. After the mass grows large enough, they can capture the lightest and most abundant elements such as hydrogen and helium, making the mass larger.
Essentially, there is a rocky core in the center of a Jupiter-like planet, but its atmosphere is thick enough to cover up the most core things.
just discussed this for a few minutes, and soon, an astronomer stood up and said: "Everyone, please listen to me first!"
The meeting room gradually calmed down.
"If you choose a satellite of a gaseous planet as the landing point, for example...this satellite."
The screen shows a huge crater hockey puck, about three thousand kilometers in diameter, 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 decelerations, the fuel reserve in the warehouse is not sufficient, and it 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 consume a huge amount of fuel. So I suggest that the first base site selection must be selected."
"Of course, if the main base is selected, according to the current level of power consumption, these nuclear fuels can still be used for about three thousand years."
Zhang Yuan frowned.
The figure of three thousand years sounds very exaggerated, but the prerequisite is the current level of energy consumption.
With the rapid development of industry, the use of electricity will definitely increase exponentially, and these nuclear fuels will soon be insufficient. For example, metal smelting and industrial production consume huge amounts of energy. Increasing population will also consume more energy. At present, it is only the lowest standard of subsistence.
I saw the astronomer continue: "If you rely on a Jupiter-like planet to act as a nuclear fuel depot, of course you don’t have to worry about energy issues."
"However, the satellites of Jupiter-like planets are chosen as landing sites. Due to the formation of these planets, certain minerals with heavier atomic weights may be lacking, such as rare metals such as scandium, yttrium and lanthanides."
"The lack of these elements will cause a huge obstacle to the development of industry. It is impossible for us to dig deep into the core of the earth. It is impossible to do this at the technical or economic level."
Engineer Ye Kaifu, who was sitting at the side, tapped his fingers on the table lightly, calculating the gains and losses. He whispered: "Compared to the more easily accessible energy, I still prefer the more accessible resources."
"Nuclear fusion is not necessary for energy, fission energy is also possible...even solar energy is fine! Don’t think that nuclear fusion is much bigger than nuclear fission."
"I think so too... Energy, only economical and cheap is the most suitable." Zhang Yuan nodded.
I saw the scientist on the stage continue: "The second choice is the two innermost planets. Especially the one closest to the star, it is not too much to call it a metal planet!"
"We can easily find all the rare metal elements."
But this planet also has shortcomings. Water resources are relatively small and organic matter is scarce. Whether there are uranium mines is another matter.
"...I have to say that the central star is a variable star, whose brightness and electromagnetic radiation are unstable, and flare will erupt from time to time. This planet has a very short revolution period, and it only takes 4 days to circle the entire star. The star is very close, and the economic loss caused by the star's flares must be taken into account..."
These are all difficult points.
Zhang Yuan frowned. When the star explodes, as long as the defensive measures are done well, there is no big problem~IndoMTL.com~ The most troublesome thing is that all kinds of remote communications will be interrupted immediately. If communication is interrupted during an important task, the loss can be great.
"...As for the two planets that seem to have a lot of water resources and an atmosphere, and are located in the habitable zone, they are temporarily out of our consideration."
"But there is a third option. We can consider a satellite of Gliese 581g."
"One of the satellites is about the size of the moon... or even slightly larger!"
A cratered planet appeared on the screen again.
The members of the Science Council are relatively sane people. Although the two planets have a lot of liquid water, they look beautiful and suitable for human survival. Even one of them, 581g, looks like an enlarged twin of the earth from a certain angle!
Many people are already on the Internet, cheering and want to travel to aliens. First release https://https://
But...
According to atmospheric spectrum analysis, the highly toxic gases mixed in the atmosphere, including hydrogen sulfide and sulfur dioxide, have a concentration 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 spacesuits at all times to ensure normal survival.
So, since there is no way to breathe the surface air freely, you still have to carry all kinds of survival equipment, it is better to land on a planet that has no atmosphere and is easy to develop.
