[NASA's latest announcement, launched in 1977, the exploration of Saturn, Jupiter, and the extrasolar galaxy space, Voyager 1, which has made outstanding contributions to the space of the extrasolar system, has been officially confirmed to be missing 3 days ago, which marks the ...... in the history of human spaceflight]

"Mom and Dad, I'm going down in the third year of junior high school after the New Year."

On Chinese New Year's Eve, I pasted the couplet at home with my sister, and Lu Yi, who came to the kitchen to stuff tofu meat with Lu's father and Lu's mother, heard the sound from the TV outside, and also told his parents about the time he left.

The loss of contact with Voyager 1 was already expected, after all, it had been sailing for more than 42 years, and the isotope thermoelectric generators on board were on the verge of depletion.

The only thing that worries all the scientists who pay attention to this matter is that the location information transmitted back by Voyager 1 before it lost contact is very abnormal, and no one knows whether this is a strange phenomenon unknown to humans in extragalactic space that caused this position anomaly, or whether someone outside discovered Voyager 1 and took it with him by the way.

Not to mention that human beings have not found any clues of other extraterrestrial civilizations at this stage, except for the discovery of traces of civilization on Mars, this proves that this possibility is very low, just from the fact that the suspicious spacecraft was captured but not shielded from the spacecraft's external signal transmission, this is a logical refutation.

If NASA hadn't sworn that they hadn't cheated on this matter, and invited relevant personnel from Russia and China to go to NASA to check the underlying hardware information of the Voyager 1 instrument, everyone would have thought that this was another conspiracy of Lao Mi, in order to distract Russia and China.

"...... so early" Hearing Lu Yi say that he was going down in the third year of junior high school, Lu's mother paused and said with some reluctance.

"Let him go down, go to his parents in the second year of junior high school, and go down in the third year of junior high school, otherwise my brother will have a headache when they come over in the fourth year of junior high school."

Compared with Lu's mother, although Lu's father is reluctant, he still agrees with Lu Yi's third year.

According to the customs of the Hakka people in northern Guangdong, the second day of the Lunar New Year is the time to go back to their parents' house to visit relatives, and the third day of the Lunar New Year is inconvenient to visit relatives.

No matter how powerful Lu Yi is outside, he has to obediently shout at his uncle and aunt at that time, if someone really asks for something, it is really difficult to refuse.

Lu's mother nodded silently, then turned her head to look at Lu Yi and said, "Xiao Yi, you are 25 years old after the New Year, and Zhang Liang is planning to get married."

I heard others say that there are very few girls in the laboratory, and in the past, you called Uncle Zhang's son at the corner of the town to do research in a laboratory in Shanghai, and he has not found a girlfriend after graduating with a doctorate at the age of 30.

You're almost going to hurry.,Don't delay it when you meet the right one you like.,Didn't there be 3 girls last time.,How is it now? ”

“......”

Looking at the old mother who entered the marriage urging mode, Lu Yi fiercely scolded Zhang Liang who got married so early with a bad head in his heart, but he had to keep a smile on his face and said helplessly: "Mom, I haven't turned 23 years old after the New Year, the 3 girls you said They gave you and my dad's New Year's gifts in my suitcase, and I planned to give them to you after eating Chinese New Year's Eve." ”

"Why don't you say you're 18? Who's going to be the first year with you in the family, wait......"

Lu's mother directly refuted Lu Yi's method of calculating the age according to the age of the year, and the next moment she seemed to react, and wondered: "The three girls have New Year's gifts? ”

......

After a short New Year at home, on the morning of the third day of the Lunar New Year, Lu Yi pinched the nose of the little princess Lu Ying, who was shouting that she would take her to Yangcheng to play in the summer vacation when she came back next time, and then said goodbye to Lu's father and Lu's mother, and went to the airport with several security personnel in a reluctant gaze.

Take the special passage to board to avoid the crowd, and the plane enters the runway under the priority guidance of the tower and accelerates into the sky.

"Professor Lu, we have gone to NASA with the Russians to confirm that the data information sent back by Voyager 1 is not fake.

In addition, we also asked to contact the Mars InSight probe in person to verify that the underlying information of the hardware of the contact instrument has also determined that there is no problem with the Mars data provided by the United States, this is the latest detection and tracking data of the Mars Insight, NASA roughly believes that the traces of civilization on Mars are just relics, and the main body of civilization has disappeared. ”

In the afternoon, when Lu Yi arrived in Beijing, a scientist from the Huaguo Aerospace Astronomy Group came to pick him up, and after seeing Lu Yi, he quickly handed him a copy of the data in his hand.

"Professor Su, do you think that the United States thinks this problem is very serious, or is it going with the flow?" Lu Yi was a little surprised when he heard that even Mars InSight had publicly asked Russia and China to verify it.

"It's a bit of a big deal."

Professor Su said with a wry smile: "Although we can't rule out the cause of the failure of the internal timer of Voyager 1, there are traces of Martian civilization in the front, and there is an abnormal position of Voyager 1 in the back, which indicates that the probability of the existence of extraterrestrial civilizations has greatly increased, and even they are around us." ”

Voyager 1 is too far away from the Earth, the communication module on it is not very powerful, and the signal is extremely attenuated, and only a few observatories can detect and receive it, so it cannot be positioned through multiple points like launch vehicles or near-Earth spacecraft.

The main way to determine the position of Voyager 1 on this side of the earth is to determine the location distance of Voyager 1 based on the timer on board, through the speed of light propagation characteristics of electromagnetic waves, through the direction of the received electromagnetic waves, and then calculate the propagation time of the signal.

"Deep space exploration didn't find any suspicious traces, right?"

Lu Yi flipped through the NASA InSight Mars tracking and exploration report in his hand, and then asked a question.

"Nope."

Professor Su shook his head and said: "After confirming that Voyager 1 was missing, space telescopes such as the Hubble Telescope, the Compton Telescope, and the X-ray Space Telescope all aimed their lenses in the direction of Voyager 1's disappearance, and no abnormalities have been found so far. ”

"It's all old rice guys."

Lu Yi couldn't help but shake his head with a wry smile when he heard the names of the series of space telescopes reported by Professor Su.

Human extraterrestrial search, extragalactic space exploration is said to be the efforts of all mankind, in fact, Lao Mi occupies more than 95 percent of the power, and the large telescopes floating in space are almost all pasted with Lao Mi's national flag.

In recent years, China has gradually increased its investment in scientific research and exploration of foreign galaxy space, which has begun to slowly change this situation, but it is limited to ground investment in the field of new exploration technology.

"Let's go, let's go back and see what Lao Mi thinks about this matter in the video conference."
