380,000 km is the distance from the Earth to the Moon Since ancient times People's Moon Look at it, yearn for it A First Look at the Past Moon Later sampling returns China's "Chang'e" starts its journey to the moon again and again Just yesterday Chang'e 6 carries the first lunar samples Safe return to Earth How were these samples dug out? Digging on the Moon What's the difference between this and digging in the earth? Xinhua News Agency interviewed International Astronautical Federation Space Transportation Committee Vice Chairman Yang Yuguang Telling the story behind the world's first lunar soil sampling 1 Chang'e 6 An "archaeological" journey to Guanghan Palace More than 4 billion years ago A diameter of approximately A small celestial body of 100 kilometers hit the moon The diameter of the current ocean is more than 2,500 kilometers. Aitken Basin Afterwards Multiple collisions not only caused The deep lunar material This also makes the area densely covered with basins "A pit within a pit" Apollo Basin This is where Chang'e 6 landed on the moon. According to Yang Yuguang The reason why I chose to land here Apart from engineering feasibility This is where the greatest scientific value lies. "If we're lucky enough Can be obtained from the far side of the moon It's very far away from this era Rock and soil samples" And the rock soil samples are so old It is hard for us to get it on earth. therefore Many Chinese people romantically call it Chang'e 6 is "going to Guanghan Palace for archaeological excavation" 2 Digging on the back of the moon “We are very careful throughout the process.” Over the years Humans have returned samples from the moon 10 times All taken from the front of the moon As for the exploration of the far side of the moon So far, only China's Chang'e has successfully achieved this twice. But even if it is the second visit to the far side of the moon With Chang'e 5 Chang'e 6 has the same technical status This trip is not easy We need to go to the far side of the moon while avoiding risks The moon's back support is weak Plus the road on the back of the moon is rough Spacecraft undergoes extreme tests … The difficulties of going back and forth are huge Many challenges As Yang Yuguang said "We're going to the back of the moon Not because it's easy Precisely because it is difficult.” “We are very careful throughout the process.” As "the only two times humans have explored the back side of the moon" China's "Chang'e" in this field One step ahead 3 Going to deep space The moon may be the first stop for humans Since ancient times The moon has played a vital role in the history of human civilization. They all play a very important role For thousands of years People continue to try to understand the moon As human exploration of the moon continues to expand The unique vacuum and low gravity environment on the moon As well as helium-3 resources, various mineral resources and water Maybe it can benefit mankind in the future Yang Yuguang Introduction With the continuous improvement of human aerospace technology And human probes travel back and forth between the Earth and the Moon again and again The scale of development and utilization of lunar resources It will definitely get bigger "Sooner or later one day The moon will become human Towards a deep space outpost For humans on a larger scale "It lays the foundation for the development of the great aerospace era" Source: Xinhuanet Xinhua Interview |
