Five hundred and six - tardigrade moss

Under the clear blue sky, a shimmering star shone in the daytime, bringing a remarkable change to this eternal world.

However, I don't know if it was an illusion, but as time passed, the star was gradually getting bigger, and it shone with a unique rhythm.

It seems to be a meteor, and it seems to be some kind of signal.

After more than an hour, finally, the star has become as big as a bucket, the whole body is blue, it is clearly visible even in the daytime, and as time goes by, it continues to grow bigger.

In the end, a spaceship with white flames shining at the bottom slowly descended from the sky, and finally landed on a relatively flat ground.

boom……

There was a low impact sound, and the spaceship landed successfully. The two nuclear-powered engines, which were comparable in size to the spaceship itself, automatically became the landing gear of the spaceship, making direct and intimate contact with the ground.

Then, there was a silence.

"The Ares landed successfully."

However, at this moment, the electronically synthesized female voice came again from the silent spaceship, "Level 1 alert is lifted, and everyone is allowed to leave the rescue cabin."

Following these words, the red lights quickly turned green on the sixteen steel coffin-like devices located in the most central part of the spaceship, which is also the strongest room of the spaceship, and then turned on with a snort.

Only then did everyone laugh and sit up one by one. They walked out of the rescue cabin with a feeling of toddler, and then jumped in unison, feeling the gravity coming from the ground in a novel way.

"I haven't felt gravity for a week, and now I feel a little uncomfortable after feeling gravity again..."

Someone suddenly spoke.

"You'll get used to it soon."

Another person continued, "However, the gravity of Mars is only two-fifths of that of Earth. It may be easy now, but when you return to Earth in the future, you will feel better. At that time, you may have to adjust your breathing for half a year before you can get out of bed." .”

"Actually, there is a solution."

A third responded, "That's being a Martian."

"Ha ha ha ha!"

Following the laughter of the crowd, some breathed a sigh of relief, while others quickly took off their spacesuits and walked towards the cafeteria excitedly.

"where did you go?"

"Of course for a glass of whiskey!"

After all, there were only a few people who went to drink. At this time, Zhou Xiong, the captain of the Ares, sat up. Instead of taking off his spacesuit, he walked directly towards the bridge.

"Captain Zhou!"

A group of people followed immediately, and everyone knew what they were thinking.

Zhou Xiong waved his hand to signal to be safe and not to be impatient. He first came to the bridge and saw the scenery outside the window at first glance.

Outside the window, there is an endless world of ice and snow.

Everyone rushed to the window with some novelty, but saw that the scenery here was not much different from the north and south poles on the earth. They were all flat. Obviously, the ice sheet firmly covered the ground below, and everywhere they could see A piece of pure white.

Not any snowflakes flutter,

There are no strange rocks either.

For all of this, everyone was not surprised. The reason why they chose to land at the south pole of Mars was to build a base. At the same time, only the north and south poles of Mars have water.

However, they know that only a small part of these ice and snow is real water ice, while most of them are dry ice composed of carbon dioxide.

"Ji Zhe, how do you feel?"

Among the crowd, a young female scientist from the Central Continent asked her companions.

"Well, at least on the outside, it looks no different from the one on Earth."

Another young scientific researcher with a somewhat cynical expression replied, "Actually, I would like to see the places where those Mars landers landed back then. That is the unique terrain."

"It's a pity that I won't be able to see it for at least a few months."

A scientist from the North American region next to him responded, "After the base is completed, we may have the opportunity to go there for a while, but not now."

When the crowd heard the words, they started discussing in a low voice.

"Okay, everyone be quiet."

At this moment, Zhou Xiong spoke suddenly, and everyone's voices fell silent. Then he raised his head and looked at a cuboid-shaped camera above his head, "Moss, release the landing vehicle and the drone, and let me explore the surrounding area. The detected data is sent."

"clear."

The female synthesized electronic voice came again, and then a huge void screen was opened in front of everyone again, and four pictures were displayed on the screen at the same time. On, and the screen is black and white imaging for night vision.

The picture seems to be a small "room", and at the same time, the four pictures are slowly turning around in 360 degrees, and then everyone only sees a door slowly opening in the room in front of the screen, and light is also revealed at the same time.

Immediately, the black-and-white image was automatically converted into a color image. At the same time, the carriers of the two cameras moved slowly out of the "room", while the other two cameras slowly floated up and flew out together.

These four cameras are obviously two landing vehicles and two drones.

Next, the landing vehicle and the drone drove out of the Ares one after another. The landing vehicle was a metal tracked vehicle with solar panels on top. Once it drove out, it immediately left a line of shallow traces on the ice sheet .

The landing vehicle started to drive on the ice field in a circle around the spaceship, trying not to miss any open space around the spaceship.

The drones rose rapidly and flew in two directions at the same time. Their goal was to fly as far as possible to draw a nearby topographical map.

"The external atmospheric pressure is 7.5 millibars, and the air composition is 95% carbon dioxide, 3% nitrogen, 1.6% hydrogen, 0.2% oxygen, 0.1% water vapor, carbon monoxide, neon, krypton and xenon, etc."

At this time, the preliminary detection results have come out, just listen to the synthetic female voice, "The outside temperature is minus 85 degrees, and the wind force is five."

"The lander samples the surface."

Zhou Xiong ordered again.

"Sampling in progress... Sampling is complete, analysis starts..."

"Dry ice on the surface accounts for 95.7%, water ice accounts for 2.2%, and there are other components such as iron oxide and silicon dioxide. No trace of microbial activity has been found for the time being."

Following the words of MOSS, everyone looked happy. Although there was enough evidence to prove the existence of water on Mars in the previous few unmanned explorations, but now when they really witness it with their own eyes, everyone's heart is full of joy. It's all beyond words.

"Captain Zhou, let me go down and investigate!"

At this moment, someone in the crowd finally couldn't wait and spoke up.

"I am coming too!"

"Let me go too!"

"And I!"

A group of people shouted loudly.

"Everyone calm down!"

Zhou Xiong quickly pressed his hands and suppressed everyone's pleas, "Don't worry, everyone. If there is no problem with the environmental detection results, we will live here in the next few months to a few years, so you don't have to worry about it for a while. .”

"However, the initial manual investigation is also necessary. If this is the case, the four continents can each select a candidate to go to the outside world for detection. This is already the limit. After all, the outside situation is unknown, and I have to be responsible for everyone's situation. "

Following Zhou Xiong's words, everyone agreed one after another, and chose people from their trio to go out for investigation.

Among the remaining four scientific researchers representing Black Light Technology, Zhou Xiong, as the captain, needs to deal with a series of sudden contingencies, so naturally he can't be the first to go out for inspection, so he gave this opportunity to a blond young man.

This is a biologist, and his name is Hannibal Caesar.

That's right, he was Hannibal who followed Chen Chen as early as the founding of Life Science City, and is now a top biology genius who is now in charge of his own work. He is also a professor-level member of God's Forbidden Zone, and Hannibal has extremely high authority in Black Light Technology.

This expedition to Mars was requested by Hannibal on his own initiative, because he had a dream of interstellar travel, and this operation took a long time to prepare, and the probability of failure was extremely small, so Chen Chen arranged for him to be on this manned mission. In the spaceship, become the first batch of scientific researchers to go to Mars.

At this time, he didn't stay with the others like the others, but came to the spaceship's laboratory, and took out a can of metal cans on a row of biological display racks.

This metal tank contains the protoplasts of a special plant - "water bear moss".

"Tardigo moss" belongs to a kind of genetically modified mosses, and its body is derived from a moss called "Moss patens".

Because the DNA structure of moss is relatively easy to repair, and various compounds can be produced in large quantities by replacing the genes of moss with genes that can produce desirable compounds, so at Chen Chen's request, Hannibal cultivated this independent 'Tardigo moss' plants.

The general process is: Hannibal uses the genes of tardigrades to transform "Moss chinensis", after all, the most powerful living animal in the earth's biosphere that Hannibal tardigrades can find.

They can withstand six times the pressure of the deepest seabed, hundreds of times the dose of human radiation, and temperatures close to absolute zero. There have been many experiments in which a group of tardigrades were exposed to a vacuum close to absolute zero. Up to 10 days, in the end there were still many of them that did not die.

The unique trick of tardigrades is the so-called "hidden life", which slows down the metabolism of life to the extent that it almost stops. When it enters the dormant state, its body water content can be reduced to less than 3%, which is worthy of the name "dehydration". But once the water is added back, the tardigrade can be "reborn from the water" like a phoenix.

So, Hannibal strengthened the tardigrade with black water. After a series of enhancements, a "monster" as thick as a human finger and covered with hard chitin appeared in reality.

This "mutated tardigrade" has very strong adaptability. It can survive for three to five years without eating or drinking. It can survive even in boiling water, and it can withstand low temperatures close to absolute zero, even in a vacuum. Zhong also only enters a hidden state, and will recover as long as the temperature rises.

In the cryptobiological state, the mutated tardigrades can survive for more than a hundred years.

So after Hannibal bred a satisfactory mutant tardigrade, he used its gene to graft on the gene of "Moss patens", although this transgenic moss did not acquire metamorphosis like the "mutated tardigrade". It has the general viability, but it can thrive even in the freezer of hundreds of degrees below zero, and its life span is longer than that of all its earth companions.

According to experiments simulating the Martian environment, this vegetation called tardigrade moss has a high probability of being able to endure the severe cold weather of Mars and become a special bryophyte that can survive on Mars.

There is not much else in the Martian atmosphere, the most is carbon dioxide, and this Phy moss can survive in the severe cold of tens of degrees below zero after genetic adjustment, and only needs a very small amount of water. If successful, it means that the Martian environment may be transformed.

At that time, as the moss releases more and more oxygen, the atmosphere of Mars will also be able to make up for a thicker, followed by an increase in temperature, which will cause a large amount of carbon dioxide buried below the surface of Mars to continue to evaporate, and then bring Higher greenhouse effect...

After the temperature of Mars reaches a certain level, there will even be more space for vegetation to live, until animals can also start to survive on Mars, and when they arrive here, the entire Mars can enter a virtuous cycle.

Of course, dreams are beautiful, but there is still a long, long way to go to reach this step, and now is the beginning of everything.

After getting the jar of moss, Hannibal followed a group of teams to the isolation cabin of the spaceship. At this time, everyone had already selected the first batch of personnel to go out for exploration. The group shouted excitedly, and some even bet , to see who can rush out of the spacecraft first and become the first person in history to step on Mars.
