Deep Space Fleet

Zhang Yuan carefully pondered these astronomical data. He saw a circle of yellow and faint purple on Glize 581g. This circle of yellow and purple, widely distributed in the dusk line, seems very neat and does not seem to occur naturally.

Because the spaceship is still seven astronomical units away from the planet, the resolution of the photo is not high, and I don't know what it is.

"Professor Fan, did you find traces of the activities of intelligent life?" Captain Zhao also saw this photo, pondered for a moment, and asked.

The astronomer immediately replied: "... No intelligent life has been found for the time being. The detectors we have emitted are still on the journey. But for now, there are no regular electromagnetic waves found in space."

"No satellites or large buildings on the surface have been observed ..." The newest 81Chinese website updates the fastest computer end: https: //

Zhang Yuan couldn't help asking: "What are these yellow ones? Such a regular global spectacle cannot always be formed naturally?"

Professor Fan said, "These unusual colors are likely to be a large number of alien plants, but the colors are slightly different from the plants on the earth. Large areas of our primary forest on the earth are green, and the plants here are yellow And purple ... "

"We suspect that these lives do not require oxygen, and energy is obtained through reactions such as sulfur oxide and nitrogen oxide. This breathing method is fundamentally different from our aerobic breathing."

Alien life?

Zhang Yuan jumped heavily in his heart, and many people sitting around couldn't help whispering.

Especially some biologists, compared with the sense of crisis, they are mostly excited. For them, any point of alien life, for the origin of life and other issues, has a strong reference significance.

"These stars have been locked by the tide. The side facing away from the star is too cold, the side facing the star is too hot, and the dusk line is neither cold nor hot, which is a very good place to live."

"Large life communities on the dusk line can be exposed to eternal light and the temperature is suitable ..."

"The strength of life is incredible."

咳 "Ahem, let's be quiet first, and in a few days, the satellite will be able to transmit the first-hand information ... but I think ..."

The professor said a long list. He means that according to the current data, there is a greater probability that there is no intelligent life. Even if there is intelligent life, it may be just some indigenous people.

Anyway, as long as these lives do not have the ability to threaten humans, there is nothing to worry about.

After human beings have reached a certain stage, they will definitely have to conduct a more detailed site inspection of the life of this planet.

Zhang Yuan and many people present were slightly relieved. What they were most worried about was that this star field originally had a strong interstellar civilization ... even if this probability is small, but once this civilization exists, they will be a ship. Man is undoubtedly the one in the middle.

"It is impossible to have civilization, and you can develop into the space age without using electromagnetic waves or satellites or something?"

"Yes."

Listening to the discussion, Zhang Yuan stood up and said, "For the sake of caution, we still need to shield the spacecraft's radio waves as much as possible until more specific information appears."

提议 The proposal was quickly adopted unanimously.

Next, after a series of discussions, combined with various mechanical equipment carried on the spacecraft, everyone chose the satellite No. 1 closest to Glizer 581g for development.

6 major planets are named by b, c, d, e, f, g, etc. This name is named in the order that humans discover. However, the satellites attached to these planets are not named. For the sake of simplicity, people directly call the largest satellite of the 581g planet as No. 1.

卫星 The diameter of this satellite is nearly 4,000 kilometers. It is bare and its surface is full of craters. The revolution period is about 14 days.

In addition to tide lock, its rotation period is equivalent to the revolution period.

The reason why I chose satellite 1 is because it is at a moderate distance from the star. Even if the star flares, the spacecraft will not be affected too much. And in theory, according to the formation conditions of the planet, it has all the resources that humans need, including various common metals, rare elements, radioactive elements, and so on.

The only drawback is that it is closer to the life planet, and there may be some potential threats. Life always has endless possibilities, who knows what weird life will be inside.

However, the distance between the satellite and the planet is 360,000 kilometers, and if something really happens, it is too late to respond. Zhang Yuan didn't believe that a creature can use its own body to break away from the planet's gravity and jump to the Earth Age.

So, being closer to the planet of life is not necessarily a disadvantage, but it may also be an advantage, at least in the future, the scientific investigation will be much more convenient.

Compared to other planets, there may be irreparable defects. No. 1 is already a pretty good planet.

但是 "But, Zhang, at this rotation speed, if a space elevator is placed on this planet, the height of the synchronous orbit will be very exaggerated!"

Ye Kaifu quietly said under the seat: "The rotation speed of this planet is too slow, I just calculated it ~ www.readwn.com ~ The height of the synchronous orbit is more than 80,000 kilometers, and we have not carried so many raw materials ... How to do?"

"No, you're wrong ..."

远 Zhang Yuan smiled and pointed out: "In this case, the laying of the space elevator must also consider the huge gravity of another planet. Therefore, our spacecraft will not stay directly in synchronous orbit ..."

"You calculate again, the gravity of the satellites cancels out the gravity of the planets, and then use the rest to calculate ..." ァ 新 ヤ ~ ⑧ ~ 1 ~ 中文 网 ωωω.χ ~ ⒏ ~ 1zщ.còм

"That makes sense!"

Ye Ye Kaifu suddenly realized, "I haven't touched this thing for a few years, and I have forgotten a bit. Fortunately, I didn't ask questions directly, otherwise I will lose my hair."

He calculated it carefully, and it took only 8,000 kilometers to get the orbital height, and he couldn't help secretly rejoicing.

This distance is good, the construction difficulty of the space elevator is greatly reduced, so don't worry about it.

As for energy issues ...

"It should be possible to find enough uranium on the planet to support the development of the first few steps of humanity."

In addition, in the case of sufficient light, you can consider laying solar panels on the sunny side of the planet to replace nuclear energy. Solar panels are a very cheap and simple technology. Zhang Yuan feels that with the equipment carried by the current spacecraft, it can be produced in large quantities in one or two years.

After some discussion, Captain Zhao claps his heart with enthusiasm: "... So it was decided, and we will open our first landing site on satellite No. 1!"

Uh ...
