Just as Li Sujia continued to Nanmen 2.b, the expedition fleet had just arrived at Barnard's Star. At this time, the fleet was hovering in a high-altitude orbit about 500,000 kilometers away from it.
A low and long sound sounded in the large and small ships in the voyage fleet. As the dormant cabins were opened one after another, batches of crew members woke up.
Among them is Liu Hanyang.
Voices of exclamation came from the mouths of the crew members. They gathered in front of the portholes and stared intently at the stunning scenery outside the window.
Liu Hanyang walked over curiously.
The scene in front of me is intoxicating and confusing. In the deep space, a star with orange light illuminates everything along the way. It is like a wisp of warm light in the cold polar night, warm and colorful.
Gentle and bright light pours on the two slowly rotating planets. The rocky giant planet closest to the star emits azure light. Under the milky white atmosphere are pieces of emerald green continents and vastness. The ocean, illuminated by orange light, is golden and splendid.
Outside the rocky giant planet is a gas giant planet, which is slightly larger than the former. The star is divided into 5 or 6 color strips of different sizes by gas strips of different colors from top to bottom. The color strips are along different lines. The direction slowly rotates, illuminated by the orange light, colorful and dazzling, as fascinating as glass.
These two supermassive planets orbit closely around their parent star, Barnard's Star. Their distance is so close that they cannot be regarded as one galaxy. Instead, they seem to be like a mutually rotating galaxy. Samsung system.
But they are indeed a galaxy similar to the solar system. Barnard's star, which emits orange light, is the absolute master of this galaxy. Although its mass is only 14% of the sun, it is still tightly locked like a shackle. Two supermassive planets with masses of 0.8 and 1.1 Jupiter respectively.
This rocky planet with a mass of 0.8 Jupiter has oceans, land and an atmosphere. It is the only extraterrestrial planet that Liu Hanyang has seen in the past nine years of his voyage that has a blue atmosphere like the Earth.
However, compared with the earth, the mass of this planet is really giant. Its mass is about 255 times the mass of the earth. It does not seem appropriate to describe it as a super earth.
It is the king of the planetary realm.
Liu Hanyang quickly dispatched a planetary civilization assessment ship and a planetary atmosphere detection spacecraft to fly into the atmosphere of the rocky giant planet.
Thirty minutes later, the planet’s civilization index, atmospheric composition, gravity environment and other parameters were gathered into Liu Hanyang’s hands.
"Commander Liu Hanyang, please go to the fleet flagship Taimiao immediately, repeat..." The central control system of the scientific research ship sent a prompt voice.
A shuttle flew away from the scientific research ship. It was like a firefly in the dark night shuttling among the mountains of interstellar ships. During its journey, Liu Hanyang received detailed information about Barnard's galaxy.
Ten minutes later, he arrived at the "Taimiao".
In a conference room of the "Taimiao", fleet commander Snet, chief of staff Zheng Yulin, and armed escort spacecraft commander Miyazawa and his party were already waiting for him.
He smiled at everyone and then sat down in his seat.
"I won't repeat the overview of Barnard's Galaxy. You must have read the relevant information halfway." Snate said.
Everyone nodded.
"The purpose of convening everyone for today's meeting is to discuss whether this galaxy is worth keeping a part of it.
(This chapter is not finished, please turn the page)
People establish territories here. "
Snate's words caused everyone to fall into a brief silence. They all activated the projection equipment on the table, and information about Barnard's Galaxy was projected into the air on the table.
They want to relive it.
Snate signaled to a lieutenant next to him, who waved gently in the air, and a diagram of Barnard's galaxy appeared in the air in front of the conference table, with three stars marking it in turn. They are the star Barnard's Star (Barnard's Star), the rocky giant planet (Barnard b) and the gas giant planet (Barnard c).
"Barnard's star is a star with a very small mass. It is an M4-type dim red dwarf star. It is not only a flare star, but also a variable star. It will erupt strong stellar flares from time to time. It affects the two planets, namely The influence of Barnard B and Barnard C is huge and is not conducive to the continuation and development of civilization." Miyazawa and his party said.
"But there is civilization on Barnard B, and its climate is very suitable. The average temperature throughout the year is 20.3 degrees, which is more pleasant than the earth." Snart said disapprovingly.
After he finished speaking, a trace of doubt suddenly flashed across his face: How could a variable star that erupts stellar flares give birth to a civilization?
His eyes looked at Liu Hanyang.
"According to stellar model predictions, Barnard's Star has been in a relatively stable period for the past 1.5 million years and has not experienced large-scale stellar flare events. 1.5 million years is enough for the birth of a civilization," Liu Hanyang said.
"But its civilization is at the end of the slave society. Measured on the time scale of Barnard's Star of more than 10 billion years, its civilization has been destroyed countless times. If we establish a territory on Barnard B, who will Can we guarantee that the eruption of a stellar flare will not destroy our territory?”
The words of Miyazawa and his party caused everyone to fall into deep thought...
Snett and Zheng Yulin exchanged glances, then faced Liu Hanyang and asked, "Commander Liu, what do you think?"
"According to Barnard B's civilization index, the eruption of a devastating stellar flare should be between 1.5 and 2 million years ago, so there is no need to worry too much. Even if it is an eruption, we can completely deal with it with our existing technology." Liu Hanyang said.
"Then you support the establishment of a human territory on Barnard B?" Zheng Yulin asked.
"Not necessarily. It depends on whether the civilization on the planet accepts us, and whether we have enough patience to establish a territory here."
"As for the first point you mentioned, we will contact the civilization on the planet. I am confident enough that they will willingly accept us as new residents. Regarding the second point, please be more detailed. You are As the commander-in-chief of the technical ships, you have a more thorough understanding of the technical data and parameters than we do, and I need you to explain them in detail."
Liu Hanyang nodded, and he signaled to the lieutenant on the side. The lieutenant waved lightly, and an icon about the atmospheric composition and gravity environment of Barnard B was displayed.
He pointed at the icon and said: "Relevant data sent from the planetary atmosphere survey spacecraft show that the oxygen content in the atmosphere of Barnard b is 5.7%, the carbon dioxide content is 33.6%, the nitrogen content is 59.15%, and the others are some rare gases. After Further exploration revealed that the organisms on this planet use carbon dioxide as their metabolism."
"The oxygen content of 5.7% is indeed a big problem." Snate murmured. After a moment, he pointed to the large area of dense smoke clouds above the planet and said, "There is a phenomenon of large-scale burning of forests on this planet. Does oxygen content have something to do with this?"
Liu Hanyang shook his head and glanced at Barnard b
(This chapter is not finished, please turn the page)
There was dense smoke like wolf smoke in the sky, and then he said: "The forest on this planet is not the kind of forest we are familiar with on the earth. It does not produce oxygen, but carbon dioxide, but there is a strange phenomenon. Oxygen levels are slowly increasing and it's not clear what's causing it."
"Slow? How do you understand slow?" Miyazawa and his party asked.
"Every 100 Earth years, its oxygen content increases by about 3 percentage points, and it will reach the Earth's oxygen content in about 300 years."
"What about the carbon dioxide content? If forests are burned in large areas, it will inevitably increase the carbon dioxide content and cause the greenhouse effect." Zheng Yulin said.
"There is no change, and there is no greenhouse effect." Liu Hanyang shook his head.
"Why is it so contradictory? And what caused the oxygen content on this planet to increase significantly?"
Zheng Yulin's words made everyone sitting there fall into thinking. They stared at the huge picture of Barnard B in front of the conference table for a long time.
It is like a blue and green spherical emerald, hanging in the dark starry sky. The golden light extends from the continent to the endless sea until it disappears in the morning and evening line.
The green continent is transparent and gorgeous in the golden light, and the blue ocean is like a shadow against the milky white clouds. It is so beautiful.
"We can't wait 300 years." Snart said, revealing a trace of deep regret in his words.
"But 300 years later is a good choice. We need to take a long-term view. Measured by the time scale of the development of a civilization, 300 years is nothing." Zheng Yulin said.
After looking around at everyone, he continued: "Also, opening up a new territory on a large scale on a strange planet with a very different environment is not something that happens overnight. It may take hundreds of years to finally take shape. , our children and grandchildren can live a carefree life on Barnard B.”
Snart thought for a moment and nodded.
"According to data sent by the planetary atmosphere survey spacecraft, Barnard b's mass is 255 times that of the Earth. In such a gravity environment, we humans simply cannot survive here for a long time." Miyazawa and his party said.
"Yes, this is fatal. Commander Miyazawa's reminder is crucial." Snart glanced at Miyazawa and his party and said worriedly, "An ordinary earthling on this planet can weigh up to 17 Tons, the super strong gravity will not only damage our organs, but also make it impossible for us to complete the simple action of opening our feet."
The conference room fell into silence again, so quiet that it was a bit uncomfortable, except for the breathing of everyone, there was no other sound.
"Hanyang, is there a solution?" Zheng Yulin asked.
"Regarding the transformation of the planet's gravity environment, we can refer to the technology of the Tiberians. They have solved the problem perfectly and may provide us with a little inspiration."
"Is there any existing technology?"
"Yes! Wu Yijun showed me this technology before the voyage fleet set sail. They obtained it from Anhe Company. The complete set of technical information should still be in Wu Yijun's hands."
"Ask Wu Yijun to quickly send the relevant technical information."
"Well, however, before implementing this technology, a detailed field investigation of Barnard B must be conducted."
"Gentlemen!" Snate stood up, looked around at everyone, and then said with confidence, "Notify all ships of the voyage fleet that after an hour of carnival, Commander-in-Chief Liu Hanyang will lead the team to land on Barnard B! "
