Humans pick up meteorites.

Idolization is a very common thing now, and many people have their favorite stars. However, Yang Kexin, a post-90s girl and groupie, has a special idol goal. She spent five years tracking the falling meteorite Chen Xing 3354 on the Gobi Desert.

In these five years, she went in and out of Lop Nur 124 times and walked through the Gobi Desert of130,000 kilometers. Facing the crisis of high temperature, bunker and sandstorm. She passed death three times. During this period, she discovered more than 600 meteorites with a total weight of more than 400 kilograms.

In private acquisitions, the price of rare meteorites is sometimes as high as11000g, but Yang Kexin, which owns more than 400kg of meteorites, refuses private acquisitions.

What difficulties and crises did Yang Kexin encounter in his five-year idol tour in Gobi?

What made her unable to pay the rent, refused to buy high-priced meteorites, and instead cooperated with the Institute of Geochemistry of the Chinese Academy of Sciences to open a public welfare meteorite science museum in her hometown? What is the current situation in Yang Kexin with about 400 kilograms of meteorites?

To answer these questions, Yang Kexin became attached to meteorites nine years ago.

In 20 12, Yang Kexin, a girl from Guiyang, born in 1990, was transferred to Hami, Xinjiang, where she became attached to meteorites.

Hami, Xinjiang is near Lop Nur. Due to the unique geographical environment of Lop Nur, the Gobi Desert here contains opportunities such as coal, iron ore and meteorites. Exploring and collecting stones in the Gobi desert is a very popular activity in the local area.

When Yang Kexin was transferred to Hami, he was the representative of coal mine electrical equipment. He has a lot of leisure time in his daily work, so he often goes to Gobi to pick up stones with friends and colleagues in his spare time, during which he knows many stone friends from his peers.

A news broke out in one of your groups. You Shi found a meteorite, which has been identified by experts.

Seeing the news, Yang Kexin got excited at once.

When I was growing up in rural Yang Kexin, I was fascinated by the starry sky: "I liked the starry sky at that time. At that time, I could still see stars in summer, and sometimes I could see meteor showers. "

Now I have a chance to see the stars in the sky. Yang Kexin, who loves the starry sky, naturally won't miss it, so she immediately contacted You Shi on WeChat and asked to enjoy it in person. The other party readily agreed.

A few days later, Yang Kexin had a chance to get close to these stars. She carefully held the meteorite in You's hand and carefully observed its touch. At that moment, she completely fell in love with this rough but textured stone.

She made up her mind to have a meteorite of her own.

Frank asked you face to face how Shi found the meteorite.

In the face of Yang Kexin's question, You Shi hesitated, not that he didn't want to tell Yang Kexin how to find meteorites, but that this line was too dangerous and too hard, and there had never been a female role before:

"Picking up meteorites is also called meteorite hunting. People who look for meteorites like me are called meteorite hunters. It is hard and dangerous on weekdays. Many men can't stand this kind of pain. At present, no one in our line is a woman. You still give up. "

In the face of You Shi's question, Yang Kexin just stared at You Shi's eyes and replied firmly: "You can take me to meteorite hunting, and then you can see my performance!"

At Yang Kexin's insistence, You Shi agreed to Yang Kexin's request, but also asked Yang Kexin to be psychologically prepared. After all, there is no shortage of courage in this industry, and there are also various professional methods to identify meteorites and find them.

Under the guidance of You Shi, Yang Kexin consulted and learned a lot of meteorite data.

She learned that only 30% of meteorites landed on land, and the desert Gobi is the best place to find meteorites because of its dry climate, which is conducive to the preservation of meteorites. In addition to its special shape and unique aesthetic feeling, meteorites also come from all corners of the universe and carry a lot of information, so we can learn more about the universe through meteorites, which has high scientific research value.

After research, Yang Kexin, who knows more about meteorites, firmly believes that he must find a meteorite of his own.

From 20 12 to 10, you invited Yang Kexin to look for meteorites. At the age of 22, Yang Kexin started her five-year journey of idolization.

Those who received the invitation prepared GPS, metal detectors and other tools according to the requirements of you, and met the team at the designated place. There are four people in this team, plus Yang Kexin.

The journey to find the stars is not easy. Even if meteorite hunters have modern technology and information about meteorite falling, it is still extremely difficult to find meteorites in the vast Gobi desert.

Zhao Zhiqiang, founder of China Meteorite Network, said: "The probability of finding a meteorite is a small probability event. Whether you can find a meteorite depends on luck and experience. It is no exaggeration to describe a needle in a haystack. "

The journey to find the stars is difficult, but no meteorite hunter is afraid of finding a needle in a haystack like this.

20 12 10, a successful four-person meteorite hunting team prepared materials and drove to the meteorite scattered area in Alatag Mountain at 4 am to search for stars.

The reason why we set off at four o'clock in the morning is that the meteorite scattered areas are mostly scattered in the no-man's land of Lop Nur. It is at least 200 kilometers, or even 500 to 600 kilometers, from Hami to the diaspora.

So experienced meteorite hunters will drive to Gobi in the middle of the night, usually at dawn the next day. At this time, the sun is not big, but the light is sufficient, which is the best time for hunters to get off and search on foot.

When Yang Kexin and his team arrived at the meteorite scattered belt in Alatag Mountain, the sun had just come out.

Experienced you ask Yang Kexin to wrap his clothes and put on a veil, eye mask and other sun protection tools. Here is Lop Nur, the surface temperature is as high as 45 degrees Celsius all the year round, and ultraviolet rays can also hurt people.

If you don't do a good job in sun protection, there are not a few people who died in Lop Nur due to heatstroke, burns and other problems.

Generally speaking, it is very difficult to find meteorites. Many times, meteorite hunters spend days and walk dozens of kilometers, but they can't find a stone.

Yang Kexin's first trip to find stars also met with the same difficulties.

After arriving at the destination, Yang Kexin distanced himself from his teammates and searched in the same direction like a fishing net, trying to find the hidden meteorites in the Gobi.

However, several hours passed and nothing was found. After lunch, the expedition continued to search, but they found that night was coming. Yang Kexin is still empty-handed.

The next day, this situation changed. The next day, the four-person team changed direction and began to search.

An hour later, Yang Kexin found a black stone in the Gobi Desert that matched the characteristics of meteorites. Picking up a stone, observing it repeatedly, trying to understand, Yang Kexin's heart was pounding.

According to what she has learned in the past, she is convinced that this is a meteorite!

After being recognized by a more experienced stone friend, Yang Kexin jumped with joy. She finally got the first meteorite in her life. Although this meteorite is very small, only 20 grams, it laid the foundation stone for her search for stars.

In this regard, Yang Kexin officially became a meteorite hunter, and whenever he has time, he will take part in idolize activities.

"The place we go most often is Lop Nur, where the Gobi Desert is everywhere. Finding meteorites is relatively easy. "

During his five years in Hami, Yang Kexin often traveled between the urban area and the Gobi Desert, with a journey of about 6.5438+0.3 million kilometers.

I have been to the famous meteorite scattered belt such as Kumutage meteorite scattered belt and tuya meteorite scattered belt to find meteorites, and I have also been to Taklimakan Desert and Mangya in Qinghai to try my luck.

"At first, I was a little inexperienced and often confused other stones with meteorites. But after a long time, I will be clear. "

"In the five years in Hami, more than 600 meteorites of various types were discovered, weighing nearly 400 kilograms."

Behind Yang Kexin's fruitful achievements, she also suffered a lot.

It is not easy to run back and forth in the desert Gobi. Desert Gobi lacks road signs to identify the location, and it is easy to get lost and the weather changes greatly. There are often extreme weather such as sandstorms, coupled with bunkers in the dark, the temperature difference between day and night is large, and there is ubiquitous exposure.

Faced with these challenges, Yang Kexin overcame them one by one.

Generally, meteorite hunters pursue meteorites, often with the mentality of getting rich, and want to get rich through meteorites in one fell swoop, but Yang Kexin is different from those people.

A buyer once found Yang Kexin, who had found many meteorites, and offered him 10,000 yuan a gram, but Yang Kexin, who was not rich at that time, was not tempted.

Even though she was unable to pay the rent for a while and had to sleep on the street, after suffering, she just refused the other party because she wanted to bring the meteorite to the children in her hometown and let them know the stars in the distance.

In 20 17, Yang Kexin's unit cancelled Hami's office, and she left the place where her five-year youth was born. After leaving, she returned to her hometown of Guizhou with more than 600 meteorites.

Yang Kexin said: "Meteorites have made me strong and open-minded, and changed my view of the world and life."

In the process of searching for stars for five years, Yang Ke often provided meteorite samples to scientific research institutions, so he also met experts such as Dr. Li Shijie from the Bureau of Geochemistry, Chinese Academy of Sciences.

After learning Yang Kexin's idea, Dr. Li Shijie was very happy, so the two people who had reached the knowledge of * * * immediately set out to prepare.

This idea was strongly supported by Institute of Geochemistry, Chinese Academy of Sciences. Yang Kexin was hired as an outdoor instructor for graduate students, and plans to set up the Science Museum as an internship base for graduate students of Institute of Geochemistry, Chinese Academy of Sciences.

2065438+June 2007, 27-year-old Yang Kexin returned to his hometown with more than 400 meteorites of different shapes, and founded the first meteorite culture popular science museum in southwest China-Guizhou meteorite culture children's popular science museum, and served as the curator.

Guizhou meteorite culture science museum is open to the public free of charge. In order to facilitate people to better understand meteorite culture, Yang Kexin has specially hired two full-time lecturers and three part-time lecturers to teach in the museum. On weekdays, he often organizes activities to go to various schools to popularize meteorite knowledge for children.

Guizhou Meteorite Culture Science Museum has been opened for four years, and Yang Kexin overcame all kinds of difficulties on the way to open it through his own efforts.

Even if her family advised her to close the door many times, she just gritted her teeth and kept the rules of free access. In four years, she held hundreds of meteorite science popularization activities on campus, which provided conditions for children to get to know the stars at close range.

When asked about the value of Yang Kexin meteorites, she replied, "They have been floating in the universe for billions of years. Every meteorite has traces of time, making it an independent story. Finding these stories has become my interest. "

In February, 20021,CCTV program "Talk" and Yang Kexin connected program exchanged views with specially invited space expert Li Haitao, who was the chief designer of the measurement and control system in China's first Mars exploration mission.

Among the meteorites on display, the largest one weighs 16kg, which was discovered by Yang Kexin in the meteorite scattered area in tuya, Xinjiang a few years ago, and the smallest one is 20g, which was discovered by Yang Kexin during his first visit to idolatry.

Li Haitao, an aerospace expert, spoke highly of Yang Kexin's move to abandon self-interest and establish a museum of meteorite culture and science. He said: "It is worthwhile to hold popular science activities to make one of them change his ideal and join the aerospace industry."

Talking about future plans, Yang Kexin expressed the hope that the scale of the Science Museum can be expanded, more meteorite science instruments can be introduced, a more perfect meteorite culture science popularization system can be established, more meteorite science popularization activities can be held, and more people can know about meteorites.

"We want to publicize through the media, enter the campus, enter the community, cooperate with more institutions and groups, carry out publicity and lectures on popular science knowledge, and let more people know about meteorite culture. It provides a place for astronomy enthusiasts and the public to understand the universe more easily and contribute to the development of popular science activities in Guizhou. "

In the face of the interview, Yang Kexin said: "I will continue to work hard to give full play to the value of meteorites, adhere to the meteorite science museum, and make my own contribution to enriching and popularizing basic science education."

With the efforts of Yang Kexin, more and more people realize the value of meteorites besides money.

In March this year, a Youshi donated a meteorite to the Science Museum. The market price of this meteorite is about100000. After hearing this, Yang Kexin asked Youshi to reconsider. After all, money is quite small, but you still insists on his decision: "meteorites are not only valuable in money."

In September, 20021year, during the popular science month in Guizhou, Yang Kexin once again took meteorites into Yunyan Primary School in Guiyang, and brought the popular science of meteorites into the campus to ignite the real idol dream for the growing children.

In the promotional film shot for his hometown of Guizhou, Yang Kexin, 3 1 year old this year, monologues at the end of the film; "You ask me what I should do when I am young, and I will answer, make a living!"

Yang Kexin explained the real idol road with his youth.

Related Q&A: What is a meteorite belt? The meteorite belt is a related question and answer: some people say that meteorites often fall on the earth. Why do these meteorites rarely land in the city center? First of all, the probability of meteorites falling in every corner of the earth is the same. However, why do we feel that meteorites only fall in the desert or Gobi desert, and rarely fall in cities?

We must start from the earth. We all studied geography in primary school. It is clear in this book that the earth is spherical. More than 70% of the earth's surface is water, and the remaining 20% contains desert forests and areas suitable for human habitation. The desert area of China (including Gobi desert and semi-arid areas) has reached about1300,000 square kilometers, accounting for nearly 14% of the national territory, mainly concentrated in the western, northern and northwestern regions. The forest area in China accounts for about 16% of the total land area. Therefore, if a meteorite falls into the water, it will be oxidized if it is not found for a long time, and it will be difficult to be found if it falls into the forest, and it will slowly disappear by oxidation. Only when it falls into the Gobi desert or desert, it is relatively easy to preserve it for a long time, because the desert and Gobi desert have dry climate and low humidity, and it is relatively easy to preserve meteorites.

Moreover, smaller meteorites burn through the atmosphere and never reach the ground. Only larger meteorites pass through the atmosphere will they fall. So we call those that burn through the atmosphere meteors and those that can fall to the ground meteorites.

Meteorites have also been recorded falling in densely populated areas. Successfully collected samples for scientific research and declared international names, such as 1976 Jilin meteorite (figure 1), 1997 Juancheng meteorite (figure 2), 20 18 Mangui meteorite (figure 3) and 2065438+.

Many people also witnessed the fall, and no records of meteorite specimens were found! For example, the Shangri-La meteorite fall event in 20 17 (Figure 5) and the Xilingol meteorite fall event in 20 14 (Figures 6, 7 and 8) have never found any specimens. (This passage comes from the official WeChat of China Meteorite Collection Club: WeChat official account: Beijing time120 17 65438+20: 07. The impact site was 40 kilometers northwest of Shangri-La County, Yunnan, China, and the explosion equivalent was 540 tons of TNT, slightly stronger than the 20 14 Xilin Gol incident (450 tons). Because the height of the air explosion is less than 40 kilometers, it is very low, so there is the possibility that the meteorite will fall to the ground before it burns out. The velocity of the asteroid relative to the earth is 14.6 km/s, and the explosion height in the air is only 37 km. It is likely that unburned meteorites fell to the ground. At that time, many meteorite lovers in China searched for several days continuously. Due to a series of factors, such as high mountains and dense forests, low visibility, changeable climate, rugged mountain roads and frequent falling of gravel, meteorite specimens could not be found.

It is difficult to collect samples every time a meteorite falls, because there are few enthusiasts who can get samples of meteorites due to climate, topography, landform, temperature and other conditions, and the probability of finding meteorites by themselves is definitely good luck. Meteorites are hard-won, and play and cherish! Cell phone code word, thanks for reading. @ HeadlineNo。 @ 么么么么么么么么
