Wandering Spaceship in Deep Space Chapter 200: Alien life!

　　 Zhang Yuan carefully pondered these astronomical data, and he saw a circle of yellow and faint purple on Gliese 581g. This circle of yellow and purple is widely distributed in the twilight line, and it seems to be very neat, unlike a natural occurrence.

　　Because the spacecraft 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, have you found traces of the activities of intelligent life?" Captain Zhao also saw this photo, pondered for a while, and asked.

　　 The astronomer immediately replied: "...No intelligent life has been found for the time being. The probe we launched is still on the road. But for now, no regular electromagnetic waves have been found in the universe."

　　 "Neither artificial satellites nor large-scale buildings on the surface have been observed..." The fastest computer terminal of the new 81 Chinese website: https://

　　 Zhang Yuan couldn’t help asking: “Then what are these yellow ones? Such a regular global spectacle can never be formed naturally, right?”

Professor 　　 said: "These abnormal colors are likely to be a large number of alien plants, but the colors are slightly different from those on the earth. Large tracts of virgin forests on our earth are green, and the plants here , It’s yellow and purple..."

　　"We suspect that these beings do not need oxygen, and obtain energy through reactions such as sulfur oxide and nitrogen oxide. This breathing method is essentially different from our aerobic respiration."

　　Alien life?

　　 Zhang Yuan's heart jumped heavily, and many people sitting around couldn't help but discuss in a low voice.

　　Especially some biologists, compared to the sense of crisis, on the contrary, the sense of excitement is the most. For them, any bit of extraterrestrial life has a strong reference and guiding significance for issues such as the origin of life.

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

　　"The large life community located on the dusk line can be exposed to eternal light and the temperature is suitable..."

　　"The strength of life is incredible."

　　 "Ahem, everyone, be quiet, and in a few days, the satellite will be able to transmit back the first-hand data... But I think..."

　　 The professor said a long list. What he meant was that according to the current data, the probability of not having intelligent life is greater. Even if there is intelligent life, it is probably only a few indigenous people, which is not to be feared.

　　 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 of development, they will definitely have to conduct more detailed field investigations on life on this planet.

　　 Zhang Yuan and many people here followed with a sigh of relief. What they worry most is that there is a strong interstellar civilization in this star field...Even if the probability is small, once this civilization exists, they This boatman has undoubtedly become a turtle in the urn.

　　"There is always no civilization. It can develop into the space age without electromagnetic waves or satellites, right?"

　　 "Yes."

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

　　 The proposal was quickly approved unanimously.

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

　　 The six major planets are called b, c, d, e, f, g, etc. These names are named in the order in which they were discovered by humans. 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, No. 1.

　　 The diameter of this satellite is nearly four thousand kilometers, it is bare, and its surface is full of craters. Its revolution period is about 14 days.

　　, coupled with the tide lock, its rotation period is equal to the revolution period.

　　The reason for choosing satellite 1 is that it is at a moderate distance from the star. Even if the star erupts with a flare, the spacecraft will not be too much affected. And theoretically, according to the formation conditions of the planet, it has all the resources needed by humans, including various common metals, rare elements, radioactive elements, and so on.

The only disadvantage of 　　 is that it is relatively close to the living planet, and there may be some potential threats. Life always has endless possibilities, who knows what weird lives will be in it.

　　 However, the distance between the satellite and the planet is a full 360,000 kilometers. If something really happens, there will be time to react. Zhang Yuan doesn't believe that any creature can break free from the gravity of the planet and jump onto the Earth Age with its own body.

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

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

　　 "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 whispered under the seat: "The rotation speed of this planet is too slow, I just calculated it~ IndoMTL.com~ The height of the synchronous orbit is over 80,000 kilometers, and we don’t carry so many raw materials... …What to do?"

　　 "No, you are wrong..."

　　Zhang Yuan smiled and pointed out: "In this case, the laying of the space elevator has to consider the huge gravitational force of another planet. Therefore, our spacecraft will not directly stay on the synchronous orbit... "

　　 "You can calculate again, the gravity of the satellite cancels out the gravity of the planet, and then use the rest to calculate..." ァ新ヤ~⑧~1~中文网ωωω.χ~⒏~1zщ.còм

　　 "It makes sense!"

　　 Ye Kaifu suddenly realized, "I haven't touched this thing for several years, and I have a little forgotten. Fortunately, I didn't directly ask questions, otherwise I would lose my head."

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

　　 This distance is good, and the construction difficulty of the space elevator is greatly reduced, so there is nothing to worry about.

　　As for the energy issue...

　　"There should be enough uranium mines on the planet to support the first few steps of human development."

　　 Moreover, if there is sufficient sunlight, 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 currently carried by the spacecraft, it can be mass-produced in one or two years.

　　After some discussion, Captain Zhao proudly said: "...Then it is so decided, to open our first landing site on the No. 1 satellite!"
