Ouyang Ziyuan was one of the first people in our country to have "close contact" with the moon.
In 1978, Brzezinski, a former U.S. security advisor, visited China and brought a national gift—a small piece of rock that the U.S. picked from the moon.
At that time, no scientist in China had done experiments on the moon. Everyone knew that there was a man named Ouyang Ziyuan who "specialized in studying things falling from the sky", so he asked him to get this sample.
In this way, Ouyang took back the legendary moon soil from far away.
He still clearly remembers the first time he saw it: "It is installed in a plexiglass column. The glass column has the effect of a convex lens. I thought it weighs more than ten grams. I'm so happy. How much research can I use it for? !"
As a result, he broke open the plexiglass pillar, and the stone rolled out, only the size of a soybean.
Ouyang took it from afar and weighed it only close to 1 gram.
"I can't bear to use up this 1 gram. 0.5 gram is enough for research. I gave the other 0.5 gram to the Beijing Observatory and said,'You can show the people what is a rock on the moon.'"
Now, after more than 40 years, Ouyang Ziyuan, an 86-year-old academician of the Chinese Academy of Sciences and Chang'e engineering consultant, has once again seen the "stone on the moon".
The difference is that this "stone" was brought back from the moon by the Chinese own probe, Chang'e-5.
On October 19, 2021, the Chinese Academy of Sciences held a conference on the research results of the Chang'e-5 lunar samples, and Ouyang Ziyuan was invited to attend.
On the same day, the Chinese Academy of Sciences and a number of institutions released it to the world. Chinese scientists revealed the mystery of the late evolution of the moon-the moon still has magma activity about 2 billion years ago. It is not only more "longevity" than people think, but also " The secret of "longevity" is actually different from what the scientific community had previously imagined. It is neither because the source area is enriched with radioactive heat-generating elements, nor is it because the magma source area is rich in water and lowers the melting point.
At the press conference of this heavy achievement, well-known Chinese and foreign media were all present, and the reporter stand alone was placed in three rows.
In addition to the results themselves, Ouyang Ziyuan's pure white and lush hair and baritone-like voice also attracted the attention of reporters.
Comparing the new results with the old experience, Ouyang Ziyuan said with emotion: "This is the result we made with our own (moon) samples. I am very excited!"
Recall that in 1978, Ouyang Ziyuan divided the 0.5 grams of lunar soil he received into several parts for experiments and published 14 papers.
"Going out to participate in international conferences, the leadership of the National Aeronautics and Space Administration (NASA) said, we didn't say anything, how do you know all about it?" Ouyang Ziyuan said: "We can also answer the moon's problem. I also know how to give it to Our "stone" was knocked down from which numbered "stone"."
The study of the moon is also a matter of scientific truth and national dignity.
Ouyang Ziyuan said that 43 years ago, the study of Lunar Soil was to welcome an "examination", and today 43 years later is an "exploration", "to make high-level and valuable research" "to show us The solidarity and cooperation and high level of scientific and technical personnel (research ability)".
It is exploration and relay.
The moon can be witnessed that in the past 43 years, a group of diligent Chinese scientists have cultivated the ability to reveal the mysteries of space.
Ouyang Ziyuan is not only impressed with today's achievements, but also with the efforts made by the new generation of researchers.
In the face of great opportunities for heroes to be useful, working overtime, sleepless nights, and even food become trivial.
Li Xianhua, one of the corresponding authors of the paper, an academician of the Chinese Academy of Sciences and a researcher at the Institute of Geology and Earth Sciences of the Chinese Academy of Sciences, told China Youth Daily and China Youth Daily that since the launch meeting of the Chang'e 5 lunar sample research project was held on July 12, 2021, His research team completed the relevant experimental analysis within 7 days, and completed 3 related papers within 14 days.
How does this "Chinese speed" spell it out?
Yang Wei, a young researcher at the Institute of Geology and Earth Sciences of the Chinese Academy of Sciences, told reporters: "You know, some people born in the 1980s have been developing related technologies since they entered the research institute.
He said: "There are not many opportunities for people to encounter such major events in their lives. We do have a sense of mission. Everyone who has a little stunt in his body wants to contribute."
Yang Wei introduced at the press conference that there are still many post-90s in his team.
He humorously said that so many post-80s and post-90s can participate in this project, it is really "breaking the four only", "The director has handed this task to us, and I will sweat for the director!"
Laughter rang out at the scene and all eyes were cast towards Wu Fuyuan, an academician of the Chinese Academy of Sciences and director of the Institute of Geology and Earth, who was sitting not far away.
The microphone was handed to him, and Wu Fuyuan said: "Our work plan is based on hours. The Chang'e 5 moon samples are attracting attention from all over the country. We are very honored to have a rare opportunity for researchers in a century. We did not have what we have now. Technology. Now that China has collected its own samples, we have a sense of pride. We must fully demonstrate the level of Chinese scientists and China's scientific and technological strength. This is our sense of mission."
