The North Pole of Mars is covered with a thick layer of ice, which is different from the ice at the North and South Poles of the Earth. The ice at the North and South Poles on the Earth is made of water, but the main component of the ice at the South and North Pole on Mars is water.
It is carbon dioxide, water is not the main component.
The temperature at the north and south poles of Mars is too low. Carbon dioxide is in a solid state, which is what we usually call dry ice. The ice layer here is composed of dry ice and ice.
It is very desolate here, without a trace of life. The occasional strong wind brings a bit of cold air. The temperature is very low, below minus 100 degrees. With such a low temperature, even if the penguins come, they cannot resist it.
live.
In the sky, a spaceship descended from the sky and flew rapidly towards the ice of the North Pole. As it got closer to the ground, its speed became very slow.
The spacecraft was not in a hurry to park, but kept flying close to the ground, seeming to be looking for a solid area. Soon, the spacecraft found a flat area with exposed rocks, and landed on it.
“The outdoor temperature is 124 degrees Celsius~”
"Atmospheric pressure 0.1 standard atmosphere~"
“Good lighting, strong ultraviolet rays~”
"..."
"It's really cold."
While Liu Daoming was wearing a special Mars landing spacesuit, he listened carefully to the sounds on the spacecraft. When he heard the temperature was more than 100 degrees below zero, he couldn't help but shudder. Such a temperature is really too cold for the earth.
Even the northern and southern regions cannot reach such low temperatures.
"If the temperature is too low, it will be difficult for life to exist. It depends on whether the temperature under the ice layer will increase. Generally speaking, if the temperature can be around zero, life can still be produced."
Li Jingxuan was also busy putting on his spacesuit. Today, the two of them also landed on Mars with the team, preparing to drill holes in the ice to see if there is liquid water at the bottom of the ice to see if they can find life.
"Hmph~"
Soon, the hatch of the spaceship opened with a burst of mechanics, and high-tech engineering vehicles drove out one after another. Liu Daoming and Li Jingxuan each drove one.
The temperature is too low, and the space suits everyone wears are very thick, and they can only rely on mechanical power to complete the work. Fortunately, scientists have already anticipated all kinds of extreme situations when they conducted scientific expeditions around the sun.
Condition.
All engineering vehicles are specially developed. Even in extreme low temperatures of more than 100 degrees below zero, they still have good performance and can be used with confidence.
"I'm going~ The baby is scared to death, Liu Daoming, look at the sky~"
"Why is this sun blue?"
Li Jingxuan, who was driving the engineer, had just stepped out of the spaceship. He looked up at the sky. When he saw a strange blue color, he couldn't help but scream.
"It's really blue and looks a bit creepy."
Liu Daoming looked up at the sky and couldn't help but said in surprise.
"This should be related to scattering. Because there is no water or vegetation on Mars, Mars has been covered with countless gravels due to erosion over hundreds of millions of years. In addition, hurricanes are rampant on Mars. In this atmosphere,
The dust particles are extremely numerous and very large.”
"These large particles of dust will scatter and scatter away the red part of the sunlight, so when we look at it from Mars, the sun is blue."
Liu Daoming thought for a while and said, although he is a scientist who studies biology, his level of physics is not good enough. The color of things like this can be attributed to the problem of light scattering in the first place.
"There should be no problem with your analysis. This kind of scattering should be Mill scattering, which scatters the red band with the same wavelength as its own particle size, causing the red part in the direction of our line of sight to be scattered, so the sun we see is blue.
The strange sun."
Li Jingxuan thought for a while and added.
"There's nothing to make a fuss about. This is a problem of light scattering. In the future, when we go to other alien planets and see purple, green, or cyan suns, don't make a fuss, otherwise we may be called bumpkins!"
Liu Daoming smiled and said that the sun on earth is red. In the future, when we go to other planets, it may be blue, purple, etc., because there are seven colors of light.
The engineering vehicle is driving slowly on the thick ice layer. The engineer has various detection instruments on it. Through these detection instruments, scientists can clearly know the thickness of the ice layer and the general situation under the ice layer.
"Just choose this place, the ice layer is not too thick."
Soon, Liu Daoming chose an area and started to get busy.
The engineering vehicles we drive are all large-scale engineering vehicles, and they are also high-tech products. For them, drilling is just a piece of cake, without any difficulty.
As the sound of machinery continued to sound, a large amount of crushed ice was continuously taken out, and the depth of the drilling was getting deeper and deeper.
While drilling, samples are also being collected from each layer so that they can be tested in the laboratory and gain a detailed understanding of the mysteries hidden under this thick layer of ice.
"The depth is 20 meters, and the temperature rises very quickly. It is already only over minus 50 degrees."
At the same time, Liu Daoming and Li Jingxuan also paid close attention to the temperature under the ice, because they knew clearly that temperature is an important condition for the existence of life.
"The depth is 30 meters, and the ice has been drilled through."
It didn't take long for Liu Daoming to open a hole in the ice and penetrate the ice.
"There is liquid water down there, and the temperature is only about zero degrees. It's incredible how much the temperature has risen."
Li Jingxuan kept observing the data transmitted by the detector and said in great surprise.
"Send a small detector in~"
Liu Daoming also got excited and controlled the engineer to launch a small fish-shaped detector through the drilled hole.
This fish-shaped detector is also a high-tech product, integrating many functions such as communication, remote control, remote sensing, detection, etc.
The detector was launched in, and Liu Daoming and Li Jingxuan nervously watched the images transmitted back by the detector.
Under the ice is a dark water world. The visibility here is very low and it is pitch black. The ice on the upper layer looks very bright here, like a sky curtain shrouding this small dark world.
The lights on the detector automatically turn on, illuminating the surrounding world.
This is a very quiet world with no waves. In the pure darkness, the silence is terrifying.
The detector continues to dive underwater. This high-tech detector was developed by scientists from the Galaxy Institute of Science to study the ocean. Theoretically, it can detect the seabed thousands of meters deep.
The further down you go, the darker it becomes, until it is completely pitch black without a trace of light. Soon, the detector reaches the bottom, which is not too deep, just a few hundred meters deep.
"The water temperature has risen to 10 degrees above zero. At this temperature, many creatures on the earth can survive, let alone those primitive life."
"It just doesn't make sense. Why does the temperature of the water get higher as it goes down?"
Li Jingxuan had been paying close attention to various data and said excitedly when he saw that the temperature had risen to about 10 degrees.
"Because there is an active volcano at the bottom."
Liu Daoming was also observing all this closely, and soon he discovered something.
The detector was slowly swam toward an area with the remote control. The temperature here was getting higher and higher. At the same time, it was obvious that there was water flowing, and the detector became unstable.
Soon, the detector came to a submarine volcano crater. When the light shined over it, bubbles could be seen floating upwards. At the same time, red magma could also be seen slowly emerging from the crater, forming a
An extraordinary underwater volcanic landscape.
"Shouldn't the core of Mars be extinguished?"
"I didn't expect that there were signs of active volcanoes."
Li Jingxuan's eyes widened. Scientists have conducted in-depth analyzes of Mars. One of the most important aspects is their guess that many billions of years ago, Mars should have been a prosperous planet with life like the Earth.
Just because the mass of Mars is too small, its core cannot burn continuously like the Earth's core, so the core of Mars was extinguished many billions of years ago.
Because the core of Mars was extinguished, the magnetic field of Mars disappeared, so that the atmosphere of Mars escaped and became very thin. Eventually, it changed from a living planet to a dead and desolate planet.
But everything we have seen now is enough to overturn this view. It is obvious that the core of Mars has not been extinguished. Otherwise, why would there still be active volcanoes?
"Incredible~The core of Mars has not been extinguished yet!"
Liu Daoming also nodded in surprise. The presence of active volcanoes is enough to prove that the core of Mars is still working continuously. It is also enough to show that the heart of Mars is still beating.
"This discovery is enough to overturn all previous understandings of Mars. Perhaps hundreds of millions of years ago, Mars really had prosperous life."
Soon, the two realized that this major discovery would definitely overturn people's previous understanding of Mars.
"There will definitely be life here, there is water, and the temperature is OK. It is better than the environment of the primitive ocean on our earth. As long as there is enough time, life can be born here, and if it continues like this, life here can multiply to
To a certain extent.”
Liu Dao was obviously very excited. The conditions here are already very good for life. You must know that the environment of the primitive ocean on the earth is not comparable to the environment here.
"Hurry up and collect samples. There will definitely be a major discovery here. Extraterrestrial life, even primitive extraterrestrial life, is definitely the most important discovery of this century."
