Chapter 11 Landing

Chapter 11 Landing Titan has a thick atmosphere, the total mass of its atmosphere is even higher than the total mass of Earth's atmosphere, its main component is nitrogen, up to 95%. Such a concentration of atmosphere represents severe atmospheric friction. Xiao Yu slowly adjusted his posture and cut into the atmosphere at a suitable angle.

Under the 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 altitude is constantly decreasing, from 3,000 kilometers to 1,000 kilometers, all the way down to 100 kilometers, entering the troposphere of Titan's atmosphere.

The speed began to decrease sharply, plummeting from two kilometers per second, to one and a half kilometers per second, one kilometer per second, six hundred meters per second...

When he was three thousand meters above the ground, Xiao Yu opened his parachute. The thick atmosphere filled the parachute, and the speed suddenly dropped to 300 meters per second.

Such a speed is only equivalent to a snail crawling in the universe. But it was still a little too fast for the landing. Xiao Yu's hull is too fragile to withstand any violent collision. Xiao Yu's ideal landing plan is to land slowly. So after the speed dropped to 100 meters per second, Xiao Yu opened the recoil rocket again.

With a series of means, the spacecraft began to descend at a speed of several meters per second, and it was still slowing down. Finally, when he was only two meters away from the ground, Xiao Yu's speed dropped to a few decimeters per second.

This speed is already within the acceptable range. The high-temperature exhaust gas ejected by the reflective rocket melted the surface of Titan, and a large amount of material began to volatilize, and then condensed in the air, turning into patches of white fog. In the white fog, Xiao Yu landed on the ground like an immortal from all over the world.

When the white fog dissipated, Xiao Yu opened the hatch. Six robots that probe their brains came out. They stood side by side like a line of soldiers.

What caught Xiao Yu's eyes was a magical world.

It was night on Titan, and the sky was dark. Covered by this thick atmosphere, the sky is basically invisible, and only a few bright stars can be observed.

Fortunately, it has a huge 'moon. ' This huge figure is very conspicuous.

That's Saturn, the slightly yellowish Saturn.

Seen from Titan, Saturn looks the same size as the Sun from Earth.

Saturn is 1.2 million kilometers from Titan. That distance is enough to coat Titan within Saturn's own magnetic field, which helps resist the solar wind from the sun. Titan orbits Saturn in about sixteen days.

The earth is shrouded in a vast darkness, which can basically be described as being out of sight. At least, the six robots lined up in front of Xiao Yu's spaceship would not be able to take any pictures with an optical detector.

Xiao Yu turned on the night vision goggles. As a result, a shocking scene unfolded in front of Xiao Yu.

There is a lake in front of him, just a few hundred meters in front of Xiao Yu. It was a huge lake. Under the wind blowing from Titan, ripples swayed on the lake. By the lake, some waves were lapping the lakeshore, making a clattering sound.

"This lake is so beautiful." Xiao Yu sighed, "Let's call you Weilan Lake."

Next to it, there is a winding river, and some liquid flowing from somewhere is 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 small hill that is not very high, short, lying there, like an ancient giant beast.

This is 1.5 billion kilometers from the earth, where the earth can no longer be seen with the naked eye. There has never been a human footprint or even a biological footprint here. It is completely shaped by the great nature, without any artificial force. As an intelligent, self-aware individual,

Xiao Yu was the first person to come and see this place.

Above, the giant Saturn. Ahead, there is a lake like a sea. Behind, is a short hill, next to a small river. Xiao Yu suddenly had the urge to cry.

Then, a sensor on one robot detected liquid falling 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 too. However, the rain on Titan is not composed of water, but liquid methane. There are also lakes, and small rivers, all made of liquid methane.

The rain gradually became heavier, and Xiao Yu could not laugh or cry, so he had to command the six robots to return to the cabin, delaying the exploration plan until after the rain stopped.

After turning on the collection equipment and various sensors on the hull of the spacecraft, Xiao Yu began to feel the rain from the alien planet blankly. This kind of feeling is wonderful, as if Xiao Yu has returned to the previous era when he lived carefree on the earth.

"I don't have a home anymore." Xiao Yu thought sadly, "I don't have the same kind anymore."

"I don't have a body either, so I can't be considered a real human."

It was raining heavily, and Xiao Yu's thoughts drifted far away. For the first time, Xiao Yu began to let go of his fanatical desire to explore and began to have energy to think about other things.

For the first time, Xiao Yu really wanted to talk to someone. However, here, apart from Xiao Yu, the only thing that can barely be regarded as a living creature is the 'Number One' captured from Jupiter in the metal box.

Xiao Yu sent out a burst of high-frequency pulses as a prank. Seeing No. 1, who was irritable and rushing from left to right in the box, he suddenly felt a little better.

The heavy rain continued for several days. The soaring lake water almost didn't even reach Xiao Yu. However, Xiao Yu was not worried at all, he was quite confident in the airtightness of his spaceship. Moreover, the lake water will recede sooner or later. Taking advantage of this time, Xiao Yu can easily collect some methane as a reserve.

Xiao Yu dismantled one of the engines on the spacecraft, made a little modification, and transformed it from burning liquid hydrogen to burning methane. Tested it, everything is fine.

After the rain, the sky is clear, and Titan's day has arrived.

Titan's sky is an enchanting dark blue. When Titan rotates to the side of Saturn facing the sun, sunlight will shine on Titan. After most of the sunlight is reflected away, a small part of sunlight will penetrate to the ground and pass through the earth. The diffuse reflection of the moon's thick atmosphere makes the sky this blue. The principle is similar to that the sky on earth is blue.

However, Titan's daytime is still very dim, just like the night when the earth is clear and the moon is not very clear, but at least with optical detectors, you can see a little something. Due to the inertial thinking of human beings, Xiao Yu has always been uncomfortable with the pictures taken by night vision devices, and the scenery in the visible light band is still more beautiful.

The sun shines in, the temperature rises a little, and then the liquid methane begins to sublime into a gaseous state, just like the evaporation of water on the earth, and the rising water level slowly recedes. Xiao Yu knew that this was the gas-liquid circulation system of methane unique to Titan.

The wet, muddy ground began to dry out. Xiao Yu re-dispatched a formation of six robots to start a field survey of the surrounding terrain.

For convenience, the robots made by Xiao Yu are all battery powered. A single charge can support them in the wild for about six to eight hours. Of course, in order to adapt to field exploration activities, Xiao Yu also made some modifications to them. The remaining two robots will stay in the spaceship cabin, in case of an accident, all the robots will be lost.

Under the unified command of Xiao Yu, the six robots followed a circle with the spaceship as the center, and started to explore the terrain.

The terrain of Titan is very flat and there are no major undulations. According to the three-dimensional images taken in the orbit around Titan, the highest peaks on Titan are no more than 300 meters.

The reason for this phenomenon is not clear to Xiao Yu, but according to calculations, it is probably related to some special geological activities, and it may also be due to the influence of Saturn.

The detection of the terrain is slowly unfolding, and a distance of one kilometer from Xiao Yu has been detected. It has been detected that there is an iron ore in this area before, and Xiao Yu is now trying to find the best mining point for this iron ore.

In front, a large area of ​​dark red attracted Xiao Yu's attention. Xiao Yu directed a robot to approach, then squatted down, turned on the flash, and the image data about these things was sent back.

Xiao Yu immediately started the analysis.

Dark red iron ore. A thought appeared in Xiao Yu's mind. Xiao Yu's mood suddenly increased.

"My luck is so good?"

Xiao Yu looked at the test data in disbelief.

This is hematite, mainly 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 has a lot of burning agents now, and even the almost infinite methane on Titan can be used as a burning agent. The only thing that worries Xiao Yu is the oxidant.

The hematites discovered almost made up for Xiao Yu's shortage of materials in two ways. This discovery made Xiao Yuda sigh.

Moreover, Xiao Yu also found that most of this hematite is an open pit vein, and there are many associated miscellaneous ores, and the types are also very rich.

Such as copper, tin, gold, silver, silicon, chromium, nickel and so on.

"This, this is simply a gift from God. Could it be that God finally thinks that I have been struggling a bit recently, so he gave me this gift? Well, it must be like this."

Xiao Yu was overjoyed, and immediately commanded six robots to move closer to him, and then jointly carried the mining equipment one by one.

Mining, mining, building bases, building spaceships...

The era of great construction is about to begin.
