The discovery of the Mars mission team is enough to shock the world. There is also a heated discussion within the space agency about whether to publish the discovery.

    "Announce it! The discovery of the Mars mission team is definitely not accidental! There must be more traces of life on Mars!" said a paleontologist from Qinghua University.

    "Yes," said Han Jie, a planetary ecologist at the space agency. "We will certainly find more evidence later, and now the results are the best. It can not only show the results of our exploration on Mars, but also get more attention and funding."

    "The American Mars ship will be on Mars in more than four months..."

    "Prepare to announce..."

    It was agreed that Du Xingyu also knew the news, and the space agency gave the opportunity to announce the news to their Mars mission team.

    This is also an opportunity for them to be recognized and honored by the world.

    In order to announce their discovery to the earth, Du Xingyu made another video.

    This time, he released the video at station B and trembling at the same time. The video is called "Mars Exploration - a cry from four billion years ago!".

    "Du Xingyu updated the video!" now more than his fans are paying attention to Du Xingyu, including many news media, even foreign space agencies and intelligence agencies.

    Du Xingyu an update, these people all open to watch.

    In the video, Du Xingyu did not directly announce their discovery on Mars, but began from the history of Mars.

    "Four billion years ago, Mars was a water world!" in the video, maroon Mars turned blue, just as beautiful as today''s earth.

    "There is plenty of rain and rivers running here. In the northern hemisphere of Mars, rain converges into a huge ocean, accounting for one fifth of the surface of Mars!"

    "At that time, Mars was a blue planet. The atmospheric pressure at that time was very similar to that of the earth. The temperature was about 25 degrees Celsius. Although the oxygen was thin, in some areas, today''s human beings can survive."

    "On the contrary, the earth four billion years ago was also full of toxic gases. The acidic ocean covered the earth''s surface, chaotic and disorderly!"

    "Everything about ancient Mars is so similar to the present earth! It has all the conditions for the birth of organic life. Did Mars give birth to organic life?"

    Du Xingyu did not answer directly, but put a computer simulation of the four billion year old Mars.

    "My God! Was Mars so beautiful before?"

    As like as two peas, I think Mars will be the same!

    "Where''s all the life on Mars?" the audience kept sending barrages and messages.

    Du Xingyu continued to explain, "why did Mars, with its atmosphere and ocean and warm as spring, disappear? Today, we have found some evidence."

    "It was a terrible space disaster!" when making this video, Du Xingyu also had a lingering haze in his heart, because he realized that behind the "death" of Mars is so similar to today''s earth!

    "When we observe the earth, we can''t find any answer, because the earth''s geological activities are frequent, coupled with volcanic activities, weathering and oceanography, the traces of disasters billions of years ago have been buried!"

    "But we can find evidence on the earth''s little partner, the moon. For billions of years, the moon has been inactive. It has suffered disasters from space... Meteorite craters record it."

    "By analyzing the decay information of radioactive elements in the crater rocks, we can distinguish the age of the rocks... Through the analysis of a large number of craters, we know a truth!"

    "From 3.8 billion years ago to 3.9 billion years ago, the moon ushered in a peak of meteorite impact."

    "At that time, countless asteroids and meteorites rushed into the Martian atmosphere and disintegrated, which was a doomsday catastrophe to destroy Mars! It is estimated that 53 tons of meteorites fell per square meter on the Martian surface!"

    "At such a high meteorite impact frequency, everything disappears!"

    In the picture, countless meteorites fall from heaven, smashing the beautiful surface of Mars into human purgatory!

    "What a tragedy, Mars man!"

    "This is what I was doing at that time!"

    "At that time, the earth was still developing, and Mars took the lead in GG!"

    "It''s terrible!" the audience exclaimed.

    "Next, let''s explore the source of this doomsday catastrophe!" Du Xingyu''s voice gradually became dignified.

    "According to the existing data and data, we simulated the formation process of the solar system, and we found that the root of the disaster came from Neptune!"

    "When Neptune moved out, it passed through the Kuiper belt. Countless icy rock objects gathered here, which is the edge of the solar system. Neptune''s gravity destroyed the orbit of the original objects, so some asteroids and meteorites were pushed into the solar system."

    "The great Mars impact 3.9 billion years ago took place!"

    Du Xingyu has remembered that the earth is about to face a disaster, which is also a big impact, just like the Mars disaster 3.9 billion years ago!

    "There was no life on Mars at that time. Even if there was life, even Martian civilization, everything disappeared under such impact!"

    Du Xingyu continued to explain, "the livable conditions of Mars have existed for hundreds of millions of years, which we call the Noah period. About 3.5 billion years ago, Mars suddenly became cold and dry. This is the Hesperian period. All the water on Mars is locked in a huge ice warehouse."

    "During this period, the underground activities of Mars were more frequent. Volcanic eruptions and underground lava melted the ice reservoir. The melted ice water poured into the surface of Mars from the southern highlands to a place called eches Valley!"

    "A 4000 meter high super waterfall has been formed here!"

    In the video, the surging and majestic flood fell from a place 4000 meters high, like countless Water Dragons rushing and roaring into the abyss!

    "This is the largest waterfall in the history of the solar system. You can imagine what a spectacular scene will be when a water cube with a length, width and height of 70 kilometers suddenly flows into a valley with a width of 10 kilometers and a length of 100 kilometers!"

    "Screenshot, screenshot, I want to use this as wallpaper!"

    "I can''t imagine. It''s so shocking!"

    "Overturned my cognition!" more than one million people watched Du Xingyu''s video at the same time.

    "After the flood swept away, the water on the surface of Mars disappeared!" Du Xingyu said, "but the disaster is still worsening, and the atmosphere on the surface of Mars began to disappear gradually."

    "Once Mars had an atmosphere with a structure similar to that of the earth. The magnetic field generated by the movement of the Martian core protected the atmosphere from the solar wind, a stream of high-speed charged particles blown from the sun."

    "When they hit the planet''s magnetic field, they will produce beautiful Aurora, which is the planet''s magnetic field protecting the planet''s atmosphere. The aurora of ancient Mars also jumped at its poles."

    "In about 3.5 billion to 4 billion years, the Martian core was no longer active and the magnetic field weakened. As a result, the Martian atmosphere began to be blown away into space by the solar wind, the ocean without atmospheric protection began to evaporate and the surface froze... Mars gradually became what it is today."

    Du Xingyu''s tone is tragic. He is telling the process of a planet from "prosperity" to "death". This is only a calculation based on the existing data. No one knows whether Mars was a vibrant world four billion years ago?

    "Did Mars ever have life? Does it still have life now?" Du Xingyu asked himself in the video. "We have found the answer. I want to tell you, yes, there is life on Mars. We found it not long ago!"

    When the video was put here, the audience were stunned, "there is life on Mars? My God, what did you find?"

    In one second, hundreds of thousands of comments were added to the video, all asking and marveling.
