"What''s the matter with Academician Du? I heard that the leaders of the Bureau called in person, but he refused to come out!" everyone in the space agency talked one after another.

    "Isn''t he satisfied with the Nobel Prize?"

    "Are you kidding? That''s a Nobel Prize. If you can win it once in your life, you''ll go to heaven!"

    "I don''t understand why he quit the Mars mission. Now the Mars mission has just begun."

    "He must have his own ideas. We''d better do our own things!" Xu Lianqiu passed by holding the folder and whispered.

    As the discoverer of Martian microorganisms, she is now the deputy leader of the Mars mission team.

    "Du Xingyu, there must be something very important hidden in his heart." although Xu Lianqiu didn''t know what Du Xingyu was thinking, her intuition told her that it was definitely not a small thing to make Du Xingyu so careful.

    On the Internet, there are also some media talking about shadowy things, but few people pay attention.

    Du Xingyu''s social account has not been updated for several months.

    Netizens sent letters asking:

    "@ earth observation, why not?"

    "Congratulations on winning the Nobel Prize. What about you?"

    "Didn''t the author go back to earth?"

    "Tell me where the address is? I want to send the blade!!!"

    "His B station account has also stopped. I don''t know what to do? Is he performing any confidential task and can''t speak?"

    Du Xingyu turned a deaf ear to all kinds of external interference. Every day, he observed and analyzed data.

    A month later, at the astronomical observatory, Du Xingyu was using a computer to compare the observation data from the Tiangong space telescope.

    "Eh? There''s a problem!" Du Xingyu found that there was a small error in the data of the precision pointing sensor.

    This error is almost negligible, but Du Xingyu believes that it is definitely not caused by machine error.

    He immediately carried out data analysis. The precision pointing sensor (FGS) collected 60 starlights per second. In an acquisition last night, the data fluctuated for 0.3 seconds. The sunlight reflected by Neptune darkened in a very short time, and then returned to normal!

    You know, these starlights are sunlight reflected from Neptune, which cannot suddenly darken and recover. Then there is only one possibility that a celestial body just flew in front of the observation point and blocked the light from Neptune! This is similar to the occultation phenomenon, but this time it is not the stellar light, but the faint light of Neptune.

    Du Xingyu''s observation directions are Neptune''s orbit and the nearby Kuiper belt. In this case, it is likely that an asteroid temporarily obscured part of Neptune during its flight.

    "Did you find it?" Du Xingyu was inspired. Although he did not directly observe the asteroid, he already had its trace. Next, he could find its flight orbit by continuous observation and comparison.

    Du Xingyu not only observed by himself, but also contacted the Haleakala Observatory and asked them to observe together.

    A week later, Du Xingyu finally determined his guess. There is indeed a high-speed celestial body, passing Neptune, flying towards the interior of the solar system.

    Its orbital target is very close to the earth''s orbit. According to the data observed every day, it can be roughly estimated that this celestial body should be an asteroid with a diameter of about 30 kilometers, mostly composed of rocks, and its flight speed is 25000 kilometers per hour.

    "Our calculation is the same!" said Professor Beth of Haleakala Observatory in horror. "Now we can only calculate its existence through FGS data, but we can''t observe it directly."

    Just imagine, Professor Beth feels cold all over, like falling into hell! An asteroid with a diameter of 30 kilometers flew towards the earth at a speed of 25000 kilometers.

    According to the average speed of 4.496 billion kilometers from the earth, Neptune will arrive near the earth in 20 years and 5 months, and then collide with the earth under the pull of the earth''s gravity!

    This will be a world-class disaster with the extinction of dinosaurs more than 65 million years ago. Who can resist it?

    "God is going to punish mankind!" Professor Beth suddenly sat down on the ground, pale.

    "Professor, calm down. This is just our calculation. There may be a deviation. Its orbit may not intersect with the earth''s orbit." Du Xingyu comforted her, but the effect was limited.

    "Professor Beth, maybe you can contact the top level of your country and see what they do," Du said

    "Yes, you must tell them about it! Don''t waste time!" Beth stood up and began to sort out the data and report her findings.

    Du Xingyu doesn''t know exactly what happened.

    He only knew that when he asked Professor Beth the next day, Beth''s eyes were dull and kept whispering, "they are so stupid! The disaster of destruction has come. No one believes that we will go to hell together! God has given up us!"

    "Sure enough!" Du Xingyu sighed, and he guessed something. Their conclusions are just astronomical observations and conjectures, and those big people are skeptical first.

    Secondly, even if such a thing really happens, some people may choose to hide it and make it public when there is no way to hide it. They are not stupid, just because they are too "smart" to calculate each other for their own interests.

    But at that time, it was too late!

    Or these people will build their own shelters, spaceships, simply give up the struggle and enjoy themselves... Come up with various ways.

    "If mankind does not unite, all means will be futile!" Du Xingyu knows this very well. "I must publish this news to the world, even if it will cause panic and anxiety... But this is an extinction disaster of mankind. There is no time for these people to continue to quarrel, hide or escape!"

    In the face of this disaster related to human civilization, people''s individuals, cities, even countries and continents are very small!

    Three days later, Du Xingyu could not contact Professor Beth. The contact person of Haleakala Observatory told him that Professor Beth was mentally unstable and sent to treatment.

    No one mentioned the previous observations. This makes Du Xingyu understand that if the breeze before the storm is too weak, it will be ignored. Only with a thunderbolt in the clear sky can we wake up the world!

    Because the asteroid has flown around Neptune, it can''t observe the difference of light with a precision pointing sensor at this time. It''s like stealth! Even if someone wants to find it, they can''t find a clue.

    Du Xingyu didn''t tell anyone again. He knew that no one would believe the news now. He needs proof!

    "According to the analysis of the speed and orbit of the asteroid and the light sensing ability of the space telescope, it will take at least 30 days to make a preliminary observation. The coordinates should be near this point... At that time, the reflection of sunlight will let the space telescope see its image directly." Du Xingyu calculated the time and place when the asteroid showed its true face.

    "Twenty seven days later, it is December 10, the day of the Nobel prize presentation ceremony." Du Xingyu stood up and looked up at the sky: "it''s time to announce the news to the world!"
