Chasing dreams and tackling difficulties together -- a review of the spirit of lunar exploration
2021-12-08
On the moon 380000 kilometers away, the chang'e-3 lander is still operating normally, setting a new record for international lunar surface exploration; On the back of the moon, chang'e-4 realized the first soft landing on the back of the moon, and the lander and yutu-2 lunar rover worked on the moon for more than 1000 days; In the front line of scientific research, the "youngest" lunar soil brought back by Chang'e 5 is constantly producing new achievements On December 17, 2020, the chang'e-5 lander with lunar samples landed safely in the predetermined area of Siziwang Banner, Inner Mongolia. The chang'e-5 mission of the lunar exploration project was a complete success. *** (on December 4, 2020, the National Space Administration released the photos of the chang'e-5 probe, the lunar exploration project, displaying the national flag on the lunar surface. The panoramic camera of the combination of chang'e-5 lander and ascent was used to take images, and the five-star red flag was successfully unfolded on the lunar surface. In addition, the mechanical arm and sampler that have completed surface sampling can be seen above the image.) Great spirit comes from great practice. The spirit of lunar exploration is a great spirit forged by Chinese astronauts and countless scientific research workers to strive for self-reliance and bravely climb the peak of science and technology. From Chang'e-1 to chang'e-5, with the in-depth implementation of the lunar exploration project, the connotation of the spirit of lunar exploration is gradually enriched, which has become a powerful spiritual driving force for the continuous promotion of the project and a winning password for the continuous success of the project, It has written the amazing pen of world aerospace development. Climbing the peak of science and technology -- the spirit of exploring the moon is another valuable spiritual wealth Under the microscope, researchers manually picked out pieces of rock debris from 3 grams of powder, and then found minerals with the size of only one twentieth of the diameter of hair, which were used to determine their "age". (lunar soil samples exhibited in the scientific and technological innovation achievement exhibition photographed at the Beijing Exhibition Hall on October 21.) The 3 grams of powder came from 1731 grams of lunar soil brought back from the moon by Chang'e 5. Through the study of lunar soil samples of Chang'e 5, Chinese scientists found that the "death" of the moon in the geological sense was 800 million years later than originally thought, which pointed out a new research direction for scientists all over the world. China once again stood at the forefront of world science and technology. Since the establishment of the lunar exploration project in 2004, in the past 17 years, Chang'e-1, Chang'e-2, chang'e-3, reentry and return flight test, chang'e-4 and chang'e-5 "six battles and six victories" have successfully completed the three-step goal of "circling, falling and returning" as scheduled. (the picture shows the image of yutu-2 at point a taken by the lander topographic camera.) With the efforts of countless astronauts, "Chang'e" and "Jade Rabbit" wrote one wonderful "Moon Palace story after another, and opened the mystery of the moon step by step. From Chang'e-1's successful flight around the moon to Chang'e-2's first multi-target exploration of "one exploration and three", from chang'e-3's accurate landing in the moon rainbow bay to chang'e-4's successful first lunar soft landing and patrol exploration of human spacecraft, and from re-entry to return to the flight tester at nearly the speed of the second universe Jump reentry to return to the earth to Chang'e 5, successfully realizing China's first sampling return of extraterrestrial objects How hard it was all the way. As a system project with the highest complexity and the largest technical span in China so far, the lunar exploration project bravely takes the lead, dares to be the "first person" and strives to climb the peak of world aerospace science and technology. "The spirit of lunar exploration is another valuable spiritual wealth for us." Zhang Kejian, director of the National Space Administration, said that the spirit of "chasing dreams, daring to explore, tackling tough problems in coordination and win-win cooperation" is a continuation of the spirit of "two bombs and one satellite" and one of the aerospace spirits with the characteristics of the times. *** Exploration is endless -- starting a new journey of interstellar exploration step by step The pace of human exploration of space is endless. At present, Chinese astronauts are making a solid start on a new journey of interstellar exploration step by step. (this is the high-definition image of Mars taken by tianwen-1 released by NASA.) In the "red planet" - Mars, which is more distant than the moon, tianwen-1 and zhurong are racing against time to carry out exploration work, constantly marking the new height of China's deep space exploration. Take the sky as the plate and the star as the son; The sun, moon and stars are all love words. Some people say that "the greatest romance of the aerospace industry is to turn dreams into reality". From the naming, people understand the romance of Chinese aerospace people—— (this is the "group photo on patrol" taken by the Mars rover zhurong released on June 11.) The lunar exploration project is named "Chang'e", the lunar rover is named "Jade Rabbit", and the relay star undertaking Chang'e 4 mission is named "magpie bridge"; The planetary exploration project is named "Tianwen" and the Mars rover is named "zhurong"... A series of familiar names not only show the long history of Chinese civilization, but also highlight the vigorous and promising of contemporary Chinese people. "Over the past 17 years, the lunar exploration project has adhered to the principle of 'integrated research and demonstration, one-stop tackling key problems and drawing a blueprint to the end' to open a new chapter in human lunar exploration and create a Chinese speed of lunar exploration." Wu Yanhua, executive deputy commander-in-chief of China's lunar exploration project, said that at present, China is advocating the establishment of an international lunar research station and striving to move towards deep space, explore the universe In the new era of promoting human well-being, there are more creations and greater achievements. "In the future, the fourth phase of China's lunar exploration project will build a basic type of lunar scientific research station, which is composed of multiple detectors running in the lunar orbit and on the lunar surface." Wu Weiren, chief designer of China's lunar exploration project and academician of the Chinese Academy of engineering, said that the basic type will have the ability of lunar scientific and technological research and technical verification of resource development and utilization, And cooperate with international counterparts to build an international lunar scientific research station. Talking about the progress and Prospect of China's lunar exploration project, Hu Hao, chief designer of phase III of the lunar exploration project, introduced that the National Space Administration is proposing to build an international lunar scientific research station, promote greater scope, wider fields and deeper international cooperation, and build an infrastructure and sharing platform to solve space science problems, make effective use of lunar resources and develop the geosphere. "It is entirely possible to realize China's manned lunar landing!" ye Peijian, technical adviser of the Fifth Academy of China Aerospace Science and technology group and academician of the Chinese Academy of Sciences, said in an interview a few days ago that starting from the successful completion of Chang'e 5 mission, the fourth phase of China's lunar exploration project and planetary exploration project will continue to be implemented. (on July 23, 2020, the tianwen-1 probe was successfully launched by the long March-5 remote-4 carrier rocket at Hainan Wenchang space launch site.) Carrying forward the spirit of moon exploration -- determined to be a "moon explorer and dreamer" in the new era Sun Jiadong, Luan Enjie, Ouyang Ziyuan, ye Peijian and other scientists are old and concerned about the sky. A group of key Aerospace experts such as Wu Weiren, Yang Mengfei, Li Dong and sun Zezhou struggle and move forward dream by dream. A group of female Aerospace experts such as Zhang Ying and Zhang Yuhua do not let their men and hold up the "Chang'e" Developing half the sky... Generations of Chinese astronauts have marked the spirit of lunar exploration with practical actions. (this is the panoramic camera of Yutu 2 patrol camera imaging the Chang'e 4 lander.) People will never forget the tears of white haired old academicians embracing each other when Chang'e-1 successfully entered the lunar orbit; It is unforgettable that academician ye Peijian and Zhang Xuan, executive director of the chang'e-4 probe project, held hands when chang'e-4 successfully made a soft landing on the back of the moon; People will never forget the days and nights when the "fat five" Long March 5 carrier rocket ran hard from failure to continuous successful launch of tianwen-1 and chang'e-5. When the elements in the myths and stories inherited for thousands of years became the name of the geographical entity on the surface of the moon, the Chinese astronauts permanently engraved the Chinese nation's dream of flying to the moon on the moon and recorded the dream journey in history. The bright moon 380000 kilometers away is the place where the "moon explorers" in the new era dream. Inspired by their dreams, they dare to overcome all difficulties and challenges. Mars, Jupiter, the edge of the solar system... When their dream of exploring the moon came true, they turned their eyes to the more distant deep space. Dream has no end, exploration will not stop. "We should do what others have done, and we should also do what others have not done. We should find ways to surpass what others have done well in the future," said Ye Peijian. (outlook new era)
