Because of being in a black barrier environment,

The sound produced by the landing capsule tearing through the air penetrated the re-entry capsule, and it had already overshadowed the sound of the small light,

Yang Meng didn't know what Xiaoguang said.

And he didn't have time to care about what Xiaoguang said

At this time, he was staring at the screen in front of him tightly and looking at the various data on it.

In this era, mankind already has a wealth of experience in alien landing,

Whether it is Venus with a surface temperature of 400 degrees,

Or a gas ice giant like Neptune,

Humans have all had the experience of landing or trying to land.

And the environment of those planets is far harsher than that of Marshmallow Star,

But even so, as an astronaut, you will not be negligent because you have rich experience in landing.

Landing on any planet with a thick atmosphere is an extremely dangerous process,

Any landing, is walking on a wire rope,

Especially in the state of black barriers, the level of danger will rise rapidly.

Fortunately, the landing capsule did not stay in the black barrier for a long time.

When the speed of the landing capsule is reduced to a certain extent, the violent friction with the air is reduced, and it naturally escapes from the black barrier state.

"Attention! In the midst of a rapid drop in altitude, the buffer parachute is about to be opened! ”

With Xiao Yi's voice,

Yang Meng only felt that the landing and return capsule he was riding in seemed to be pulled by something.

The unpleasant noise outside the cabin also disappeared at this time,

This feeling, Yang Meng knows very well, is the effect of the cushioning parachute.

The thickness of the atmosphere of the marshmallow star is greater than that of the Earth, and the atmospheric pressure close to the surface is also higher than that of the Earth.

This means that the closer you get to the surface, the denser the air becomes, and the more effective the parachute is at cushioning.

Looking at the ever-changing variety of data on the screen,

He couldn't help but recall what he had experienced on his first atmospheric re-entry mission.

Although the technology of human landing and return is extremely mature,

But in order to successfully land on a planet,

or do you need to go through a lot of training,

And his first training target at that time was Mars.

Because the core activity of Mars is not high, its own magnetic field is very weak.

And a weak magnetic field cannot protect its own atmosphere,

Under the blowing of the solar wind, the atmosphere of Mars has been stripped of only one percent of the Earth's atmosphere.

In this case, the effect of the parachute on the deceleration of the aircraft is very limited.

In order to ensure a smooth landing on Mars,

The Mars rovers of early humans did not use extremely large parachutes.

It is a combined landing device that uses three parachutes in a group.

In such a rarefied atmosphere, it was not an easy task for early humans to land.

When the landing module reaches the surface of Mars, a recoil device must be used to avoid damage to the landing module by impact.

"Compared to Mars, the landing conditions on Marshmallow can be said to be very convenient!"

"Thick atmosphere, almost windless environment......"

"It's a pity that such a planet appeared in Nanhe No. 3!"

Thinking that this galaxy had come to the end of his life, he couldn't help but sigh secretly.

When the three as of the South River broke out,

The gravitational binding ability of the entire Nanhe San will be greatly weakened.

It can be expected that when the time comes, the marshmallow star will escape from the three-star system of Nanhe and start its own wandering life.

At this time, because the landing capsule turned on the parachute deceleration device, the speed of the landing capsule began to slow down.

Like a dandelion, it slowly fell towards the ground of the marshmallow star,

The whole landing process has also entered a relatively safe stage,

A small light in the cabin,

can finally float smoothly in the protective cover,

It's just that the flickering frequency on his body seems to indicate that this little light is in a state of shock.

"It's such a troublesome thing to land on a planet!"

Yang Meng, who was thinking about the ending of the marshmallow star, finally heard Xiaoguang's voice this time,

"The process of landing on this planet is not too troublesome!"

"You mean there's a more troubled planet?"

"Yes!"

Yang Meng groaned slightly, and then told Xiaoguang about the several planetary environments he had experienced.

After listening to the unique environments described by Yang Meng

The small light flickered violently a few times, and then made a voice with inexplicable emotion:

"I see!"

"Once upon a time, we only thought about leaving our own planet,

But I never thought about how to land on other planets?

What a pathetic thing our civilization is! ”

Seeing Xiaoguang so emotional, Yang Meng couldn't help but glance at the constantly flickering point of light,

Xiaoguang's words made him a little puzzled,

A civilization that has existed for countless years, how can it not consider the result after doing something,

This is not common sense, and it is impossible for such a civilization to last so long without considering the consequences.

Thinking of this, Yang Meng asked Xiaoguang this question directly.

"Consequences?"

The light flickered twice before responding:

"In fact, after our civilization has reached that point, when it thinks about many things, it no longer thinks about the consequences of doing so.

It wasn't until there were some crises that I realized that some things were irreparable! ”

Speaking of this, the frequency of flickering on Xiaoguang's body became more obvious, and he didn't know if it was an illusion, Yang Meng felt that Xiaoguang, who had no visual organs of a living body, was looking at him,

"During this time, I have also observed you, although you can remain rational,

But as a living organism,

The demand for the ecological niche will never end, this is the instinct of living beings, and I think there are some unscrupulous existences in your civilization!"

Hearing Xiaoguang say this,

In Yang Meng's mind, the gray force of the asteroid belt that had been wiped out inexplicably appeared,

and the Kuiper Belt Gray Forces, which were redeveloped from the remnants of the asteroid belt,

Although the gray forces belong to the same human camp as the human forces,

But the gray forces act without care, gene editing, disorderly cloning, and arbitrary modification of the human body.

This kind of power continues to expand, and it is unpredictable for the human beings on the earth.

Maybe it's like the war between the living forms and the machines that once took place in the Rutan civilization,

The thought that human beings would die in some kind of special infighting flashed through his mind, but then Yang Meng shook his head and said:

"We are different from you, we have left our own planet and walked towards the vast universe!"

"Yes! You're lucky! ”

After Xiaoguang said this, the environment in the cabin instantly quieted down,

Only the sound of various instruments and equipment echoed in the cabin. And this dullness was not broken until the slight vibration of the capsule,

"We're here!" Yang Meng spoke.

"I can feel that the planet is extremely rich in resources!"

"You can feel it!"

Hearing Xiaoguang's words, Yang Meng remembered that Xiaoguang not only has advanced material decomposition and recovery capabilities,

It also has excellent material detection capabilities......

At the beginning, the large metal mine on Ice Deimos was found by Xiaoguang,

As a civilization with a scarcity of heavy elements, prospecting and recovering minerals seems to be an extremely important skill.

"Speaking of which, that piece of metal was ...... in the first place"

Yang Meng's consciousness fluctuated slightly, and then he returned to the matter in front of him,

can think that the landing return capsule has just landed on a strange planet,

There were still many things to do, and there was no room for cranky thoughts, so Yang Meng stopped the thoughts in his heart.

"Put this matter aside for now, since Xiaoguang still has the ability to prospect, the stay time in Nanhesan can be reduced!"

Thinking of this, Yang Meng's first instruction to Xiao Yi,

"Xiao Yi, detect the environmental data of the landing site!"

"Understood!"

And the little light on the side saw that Yang Meng landed on the ground of the marshmallow star and didn't go out, so he flickered and asked:

"Now that you've landed, what are you waiting for?"

Xiaoguang, who is in the Rutan Star civilization, faces the situation of landing on another planet for the first time,

I can't wait to go out and have a look.

However, in the face of Xiaoguang's urgent thoughts, Yang Meng shook his head lightly, saying that there was no need to worry,

Landing on a strange planet, not caring about anything, just open the hatch and go out is a very risky behavior,

Although there have been some detections by probes near the landing site before,

But according to the safety rules for exiting the cabin, Yang Meng has to be tested again.

The reason why such a cumbersome and multiple testing process is set is because human beings have suffered in this regard.

When mankind entered the solar system era and successfully landed on Mars, they planned to march to the next planet.

But there are a large number of celestial bodies outside the orbit of Mars,

Some of the great powers of humanity have also disagreed on which planet to go to.

Whether it is Jupiter or Saturn, or even Uranus and Neptune after all, there are a large number of moons, and some of these moons are unique.

The final result of the discussion was:

Some large human forces directly skipped those Jupiter moons that were closer to Mars,

Set your next landing exploration target as Titan,

And the reason for this plan is very simple,

Titan, as the second largest moon in the solar system,

It is the only planet in the entire solar system that has a liquid ocean on the surface of the earth, except for the Earth.

To be precise, it is the only planet other than the earth that has liquid rivers, liquid lakes, and oceans on the surface, similar to the earth's rainfall atmosphere.

It's just that unlike Earth:

In the earth make up rivers, lakes, oceans, the main substance is water,

The main liquid substances on Titan are hydrocarbons.

In the face of such a special planet,

It can be said that it is the most worthwhile planet to explore among the major moons of the solar system,

As early as the end of the 20th century, after discovering the peculiarities of the possession of this planet,

There was no hesitation, and a lot of financial resources were spent,

On October 15, 1997, Cassini launched the Saturn probe, and on board the Huygens Titan landing probe,

The Huygens successfully landed on Titan in 2005.

And at 0:19 on January 15 of that year, the first batch of data was successfully sent back.

It's a pity that because the Huygens's battery can only last for half an hour,

Titan also has a thick atmosphere, and Titan is too far away from the sun to be powered by solar energy

The detector soon became inoperable.

It was also that exploration that let mankind know that on a planet other than the earth, there is a planet with a liquid ocean on the surface.

And it was found that the marine material of this planet is mainly methane and some hydrocarbon materials.

And hydrocarbons are extremely common on Earth,

At that time, the gasoline fuel filled by human motor vehicles was a common hydrocarbon.

Therefore, the liquid state on Titan's surface can be seen as similar to that of gasoline.

Such a special planet, in the nomination of scientific researchers, was elected as the primary exploration target with a high number of votes.

At that time, mankind had just broken through the controlled nuclear fusion technology,

Beyond Jupiter's moons, it is not difficult to explore Titan.

Of course, not all human forces choose to explore Titan, and some forces with limited capabilities still choose the closer moons of Jupiter.

And those forces that probe Titan,

Following the general detection process, which was smooth at first, the launch of the probe, the detection of the environment of the Titan landing site,

After determining the safety of the landing site, astronauts were sent to land on Titan.

began to scramble for enclosure, intending to establish a base on Titan,

However, in the process, a tragic accident appeared in the last stage after the landing,

Before landing, the probe detection stage.

Humans have discovered the presence of highly toxic cyanide on Titan

In order to deal with this terrifying and highly toxic substance, all major human forces have also done a lot of protective work for this purpose.

However, among the human forces, there are always some forces that have a fluke attitude towards the aerospace project.

In the face of the dangerous environment of Titan,

In order to seize the opportunity, the astronauts of a certain force rushed out of the capsule without probing the surrounding environment of the landing site.

In the eyes of this force,

They already have a lot of experience in landing, and the probe has done some detection of the surrounding environment before,

They don't waste time at all, in probing,

Under the guidance of this kind of thinking, the forces on this side did not test the environment of the landing site too much, and then opened the cabin and went out.

The spacesuit has a strong airtightness and will not be invaded by toxic gases.

But the ground command center of this force found that

His own astronaut lost contact, and he had to turn to other forces for help.

After waiting for the astronauts of other forces to go to the landing site of this force,

But it was found that the astronauts on it had all lost their lives.

Such a major accident immediately attracted the attention of all human forces,

And the causes of the accident are not complicated,

After the landing capsule landed on Titan,

Because the landing capsule still maintains a certain residual temperature,

Although this residual temperature is not high, it is a high-temperature object compared to the average surface temperature of minus 179 degrees Celsius on Titan.

At this temperature,

Titan's gas-liquid environment will continue to form a special oil-liquid interface on the surface of the "hot" landing module.

This oil-liquid interface evaporates rapidly under the "high temperature" of the landing module, and causes the carbon and nitrogen triple bonds of cyano compounds in the atmosphere to recombine in the hydrocarbon-liquid environment.

The result is a highly toxic substance that humans have never been exposed to.

This new substance will surround the landing module in a cloud-like form.

If the test is carried out before leaving the cabin, this substance will be detected immediately.

Although humans have not seen this cyano compound, and its properties are not clear,

However, most of the cyanide is toxic.

The spacesuit can withstand this highly toxic substance and can move outside,

But the astronauts had to return to the landing capsule and take off their spacesuits.

The air pressure chamber outside the landing capsule can filter out 99.9% of foreign gas molecules,

It is forbidden for astronauts to bring foreign poisonous gases into the cabin after the air pressure is balanced, which will damage the environment in the cabin.

Moreover, even if the toxic gas enters the cabin, under the circulating filtration, the toxic gas molecules can be diluted to a low toxic concentration to a large extent.

However, the new gas molecule that appeared happened to be a new poisonous gas that mankind had never seen before.

The circulatory system was also unable to filter, and a tragedy was created.

……

Recalling this event written in the history of astronautics,

Yang Meng didn't dare to be careless about such an alien environment in front of him,

"As the old saying goes, any clause written into the aerospace safety rules and regulations seems unreasonable, but someone has paid for it with their lives!"

In waiting, time passes slowly,

Yang Meng was not in a hurry, but the small light on the side kept flickering, and he seemed to be a little impatient.

Just when Xiaoguang wanted to urge again, Yang Meng finally spoke up:

"It's basically safe, and you're ready to go out!"

Hearing Yang Meng's voice, the small light flickered, and the entire point of light revealed excitement

Seeing such a small light, Yang Meng shook his head gently,

He can still understand the state of Xiaoguang,

After all, when he left the earth and landed on Mars for the first time, he also had such a state.

Yang Meng withdrew his gaze from Xiaoguang,

Looking at the data just explored, compared with the outer atmosphere of the marshmallow star, the atmospheric environment on the surface of the marshmallow has undergone some changes.

The most abundant gas in the outer atmosphere is hydrogen, which accounts for 91% of the atmospheric content, followed by nitrogen, methane and other gases.

The composition of this gas is not normal,

Hydrogen, as the lightest atom, is extremely susceptible to external forces.

If it was in the interior of a star system, it would have been blown away by the violent stellar wind power.

But it's too far away from the star, and hydrogen can still stay around Marshmallow, which is another reason why the planet's outer atmosphere can maintain such a strange shape.

And when you get to the surface of this planet,

Yang Meng found that the most abundant gas in the atmospheric structure changed from hydrogen to nitrogen, which accounted for 57% of the air.

"So it looks like this planet is still a nitrogen-rich planet!"

"It's not common on this kind of planet!"

After Yang Meng has experienced so many planets,

I've only encountered three nitrogen-rich planets,

One is the Earth, which contains 78 percent of the atmosphere with nitrogen

The other is Titan, which contains 98% of the atmosphere

These two planets are the only two nitrogen-rich planets in the solar system.

And in addition to these two planets,

The other one is the Rutan star B he encountered in the Rutan system.

That is, the planet where Xiaoguang is located, and that planet is also a nitrogen-rich planet.

Now he has met the fourth nitrogen-rich planet.

Nitrogen is a very important element for life on Earth.

Human genes are composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus, and plants cannot grow without nitrogen.

"This planet has the basis for life!"

"If it's still in its place, maybe it has a different scenery!"

……

Looking at the various data on the panel, after making sure that it was safe outside, I was finally ready to get out of the cabin.

Yang Meng untied the shackles on his body and subconsciously wanted to float forward.

But the gravity on the planet made his knot step on the bilge solidly.

Feel the long-lost down-to-earth,

Yang Meng was the first to feel an unbearable tingling sensation, which passed from the soles of his feet into his brain.

This caused him to lose his mind for a short time.

Xiaoguang on the side saw that Yang Meng's expression was a little abnormal, so he asked out loud:

"What's wrong with you?"

"Nothing!"

Yang Meng shook his head and sighed in his heart:

"That familiar feeling is back!"

Faced with this situation, he seemed to be prepared and took off the spacesuit on his body.

Then I took out the contents of the toothpaste package from a box next to the seat.

Some pink paste-like substance was squeezed out of it,

Apply it to the soles of your feet, and the abnormal tingling sensation on your feet quickly disappears.

Xiaoguang on the side kept staring at Yang Meng's movements, and seemed to see something:

"You're so fragile as living beings!"

Seeing Xiaoguang say this, Yang Meng smiled and didn't respond anything.

It didn't matter much to him.

His time is different from his grandfather's space age,

In those days, after an astronaut stayed in the space station for a long time, there were a series of changes in the body,

Such as bone loss and muscle nerve atrophy, etc.,

Therefore, when astronauts land on Earth, they need to be placed on recliners in order to ensure their health and safety in the face of the new gravity environment.

When you return to the base, you have to do a lot of recovery training to get your body back to normal.

And the development of aerospace technology to this era,

With the development of modified centrifuges, the combination of low-temperature dormancy technology and microgravity centrifugation technology has emerged.

Such a technology can already avoid most of the problems that astronauts will have in a weightless environment.

Unfortunately, even with centrifugal microgravity technology, some of the health problems caused by weightless environments are reduced.

But there are still some problems that have not been completely solved.

That's the problem of pain in the soles of the feet.

Because astronauts float around in a weightless environment for a long time,

Because the stratum corneum on the sole of the foot loses the pressure of the body, it will slowly shed over time until the tender skin inside is finally exposed.

Without the protection of the stratum corneum, the soles of the feet are extremely sensitive.

If you have the cuticle on the sole of your feet, it will be unbearable to be tickled with a feather.

When you lose your cuticle, the soles of your feet become more sensitive, and your itching becomes tingling.

And the soles of the feet, which are non-fatal and non-important problems, do not manifest themselves in a weightless environment.

Therefore, human researchers do not pay much attention to this kind of problem.

After all, if this kind of problem occurs, it means that the astronauts have returned to the surface.

As long as it is repaired for a while, it can be restored.

In the eyes of some researchers, there is no need to waste funds in this area.

And after the breakthrough of controlled nuclear fusion technology,

The speed of the spacecraft is getting faster and the time to reach other planets of the solar system is getting shorter, and this symptom is less pronounced.

Fortunately, as mankind enters the space age,

A large number of technologies, funds, and talents have poured into aerospace-related fields.

Coupled with the fact that mankind has to carry out pioneer exploration programs,

In order to ensure that astronauts can gain activity in other galaxies far from Earth.

This kind of trivial problem has also been studied by some people.

……

Yang Meng applied the ointment,

I turned on a UV lamp and shone it on the soles of my feet.

Then put the spacesuit back on,

After standing up and taking two more steps to make sure there were no problems, he headed for the barobar.

"Are you finally out of the cabin?"

The light flickered twice and followed.
