Chapter 11: landing

Chapter 11 Landing Titan has a thick atmosphere, and its total mass is even higher than the total mass of the Earth ’s atmosphere. Its main component is nitrogen, which is up to 95%. An atmosphere of this concentration represents severe atmospheric friction. Xiao Yu slowly adjusted his posture and cut into the atmosphere at an appropriate angle.
Under high-speed friction, the outer shell of the spacecraft quickly turned red. But all this was expected, Xiao Yu was not worried at all.
The height of the radon continued to drop, from three thousand kilometers to one thousand kilometers, down to one hundred kilometers, and entered the troposphere of Titan's atmosphere.
The speed began to decrease sharply, dropping straight from two kilometers per second, 1.5 kilometers per second, one kilometer per second, and six hundred meters per second ...
Until three kilometers from the ground, Xiao Yu opened the parachute. The thick atmosphere will make the parachute full, and the speed suddenly drops to 300 meters per second.
This speed is only equivalent to a snail crawling in the universe. But it was too fast for a landing. Xiao Yu's hull was too fragile to stand up to any violent collision. Xiao Yu's ideal landing plan is a slow landing. So after the speed dropped to one hundred meters per second, Xiao Yu turned on the recoil rocket again.
With a series of measures, the spacecraft started to land at a speed of several meters per second, and it was still slowing down. Finally, when only two meters from the ground, Xiao Yu's speed dropped to a few decimeters per second.
This speed is already within the range that can be tolerated. The high-temperature exhaust from the reflection rocket melted Titan's surface, and a large amount of material began to volatilize. Then it met condensation in the air and turned into a white mist. In a white mist, Xiao Yu, like an immortal from nine heavens, landed on the ground.
After waiting for the white mist to disperse, Xiao Yu opened the hatch. Six robots with probes came out. They are side by side, like a team of soldiers.
What Xun Yu sees is a magical world.
I was on Titan's night, and the sky was very dark. Under the cover of this thick atmosphere, the sky can hardly see stars, and only a few bright stars can be observed.
I ’m lucky, it has a huge ‘moon. ‘This huge figure is very prominent.
This is Saturn, a slightly yellow Saturn.
看 When looking at Saturn on Titan, it looks as big as looking at the sun on Earth.
Saturn is 1.2 million kilometers from Titan. This distance is enough to cover Titan within Saturn's own magnetic field, which helps to resist the solar wind from the sun. Titan orbits Saturn for about sixteen days a week.
The earth is shrouded in vast darkness, which can basically be described by reaching out with five fingers. At least, the six robots standing in line in front of the Xiao Yu spacecraft could not take any pictures with the optical detector.
Xiao Xiaoyu turned on the night vision. So, a shocking scene was shown in front of Xiao Yu.
There is a lake in front of Xun, just a few hundred meters in front of Xiao Yu. It was a huge lake. Under the wind blowing on Titan, there were ripples on the lake. There were some waves hitting the shore of the lake, making a rattle sound.
"This lake is so beautiful." Xiao Yu sighed, "Just call you Blue Lake."
Next to the urn, there was a crooked creek. I didn't know where some of the liquid from the river slowly merged into the lake.
At the foot, there is a slightly mottled ground, like sand, and some stones, similar to the Gobi Desert above the earth. At the rear, there is a not-so-high hill bag, short, lying there, like an ancient monster.
This is 1.5 billion kilometers away from the earth. Here, the earth cannot be seen with the naked eye. There has never been a human footprint or even a biological footprint. It is completely shaped by great nature, without any artificial force. As a wise and self-conscious individual, Xiao Yu was the first person to come and see this place.
Above you, there is the giant Saturn. Ahead of it, there are lakes like the sea. Behind it is a dwarf hill pack, next to a small river. Xiao Yu suddenly had an urge to cry.
Then, a sensor on one robot detected that liquid had fallen from the sky, and then the remaining five robots also detected it. Xiao Yu immediately realized a problem.
It's raining.
Yes, there is rain on Titan. However, the rain on Titan is not composed of water, but liquid methane. There are also lakes and small rivers, all made up of liquid methane.
The rain gradually increased, Xiao Yu couldn't help crying and had to command six robots to return to the cabin and postpone the exploration plan until after the rain stopped.
Opened the collection equipment and various sensors on the hull of the spacecraft, Xiao Yu began to feel the rain of the alien planet blankly. This feeling is wonderful, as if Xiao Yu is back to the time when he lived on the earth carefree.
"I don't have a home anymore." Xiao Yu thought sadly, "there is no such thing."
"I don't have a body, and I can't be considered a real human."
After a heavy rain, Xiao Yu's thoughts drifted far away. For the first time, Xiao Yu began to let go of his fanatical desire for exploration and began to have energy to think about the rest.
For the first time, Xiao Yu wanted to talk to people. However, here, besides Xiao Yu, the only one who can barely be regarded as a creature is the ‘number one’ captured from Jupiter in a metal box.
Xiao Yu sent a burst of high-frequency pulse like a prank, looking at the irritability inside the box, the number one rushing to the right, suddenly feeling better.
The heavy rain lasted for several days. The rising lake almost didn't reach Xiao Yu. But Xiao Yu didn't worry at all, he was quite confident in the tightness of his spacecraft. Moreover, the lake water will recede sooner or later. At this time, Xiao Yu can conveniently collect some methane as a reserve.
Xiao Xiaoyu disassembled an engine on the spacecraft and slightly modified it to transform it from burning liquid hydrogen to burning methane. Tested a bit, everything is fine.
The rain was sunny and Titan's day arrived.
The sky of Titan is an intoxicating dark blue. When Titan moves to the side of Saturn facing the sun, the sun will shine on Titan. After most of the sunlight is reflected away, a small part of the sun will penetrate the ground and pass through the earth. Diffuse reflections of the thick atmosphere of Wei Liu made the sky blue. The principle is similar to the blue sky on the earth.
However, Titan's daylight is still very dim, as it is clear on the earth and the moon is not very bright at night, but at least with the optical detector, you can see a little. Due to the inertia of human beings, Xiao Yu is still not very suitable for the pictures taken by night vision, and the scenery in the visible light band is still more beautiful.
The sun's rays came in, the temperature increased a bit, and then liquid methane began to elevate to a gaseous state, just like the evaporation of water above the earth, and the rising water level slowly receded. Xiao Yu knows that this is the unique gas-liquid circulation system of methane on Titan.
Damp, the muddy ground began to dry. Xiao Yu re-sent a formation of six robots and began a field survey of the surrounding terrain.
For convenience, Xiao Yu's robots are battery-powered. A single charge can support them for six to eight hours in the wild. Of course, in order to adapt to the field exploration activities, Xiao Yu also made some changes to them. The remaining two robots were left behind in the spacecraft's cabin to prevent accidents and all robots would be lost.
萧 Under the unified command of Xiao Yu, the six robots followed the circle, with the spacecraft as the center, and began to explore the terrain.
The terrain of Titan is very flat and there are no large undulations. According to the three-dimensional stereo images taken on the orbit around Titan, the highest peak on Titan is not more than 300 meters.
The cause of this phenomenon Xiao Yu is not very clear, but according to the calculation, it may be related to some special geological activities, or it may be due to the influence of Saturn.
The exploration of the terrain is slowly unfolding, and it has already detected a distance of 1,000 meters from Xiao Yu. An iron ore has been detected in this area before, and Xiao Yu is now looking for the best mining point for this iron ore. UU Reading www.uukanshu.com
In front of him, a large dark red attracted Xiao Yu's eyes. Xiao Yu directed a robot to approach, then squatted down, turned on the flash, and the image data about these things was transmitted back.
Xiao Xiaoyu immediately launched an analysis.
Dark red iron ore. An idea came to Xiao Yu's mind. Xiao Yu's mood suddenly increased.
"My luck, how could it be so good?"
Xiao Xiaoyu looked at the test data unbelievably.
This is hematite, whose main component is composed of iron oxide, which can be separated into iron and oxygen by technical means. Iron can be used to make steel, and oxygen can be used as an oxidant.
Xiao Yu still has many combustion agents. Even Titan has almost unlimited reserves of methane can be used as a combustion agent. The only thing that makes Xiao Yu worry is oxidant.
The hematite discovered by Xun almost made up for the shortage of Xiao Yu in two aspects. This discovery made Xiao Yuda sigh.
And Xiao Yu also found that most of this hematite is open-pit veins, and there are many accompanying miscellaneous ore, and the species are also very rich.
Copper, tin, gold, silver, silicon, chromium, nickel, etc.
这 "Here, this is almost a gift from heaven to me. Does God finally feel that I have been suffering a bit recently, so he sent me this gift? Well, it must be."
Xiao Yu was overjoyed, and immediately directed six robots to move closer to him, and then moved one mining equipment together.
Mining, mining, building bases, building spaceships ...
The grand construction era is about to begin.
