In May, China's Chang'e-6 successfully entered orbit around the moon after eight days in the air, taking a decisive step towards the lunar exploration program and preparing it for sampling on the far side of the moon.
The previous Chang'e-5 has made history, and now, facing the Chang'e-6 that is about to land on the surface of the moon, we have reason to believe that she will also leave a unique mark in the history of China's aerospace industry. This is the progress of China's lunar exploration program, and it also shows our unswerving commitment to exploring the unknown.
1. The shaping of Chang'e-6: China's lunar challenge
In the vastness of the universe, what is hidden on the side of the moon that is always facing away from the earth has always aroused people's curiosity. However, for Chang'e-6, achieving this seemingly unimaginable feat is gradually becoming a reality.
At this very moment, China's lunar exploration program is demonstrating its astonishing determination and fearless courage, and its long journey is like a heroic adventure, with rollercoaster ups and downs and tensions. Every progress is driving innovation in lunar exploration technology, and Chang'e-6's mission is to continue to innovate and make breakthroughs in the history of human spaceflight.
And just after Chang'e-6 successfully entered the orbit around the moon, it entered the critical stage of preparing for the entire landing. Like weights hanging at the ends of the scale, success and failure, joy and loss are opposed. China's Chang'e-6 operates in a very different mode from its predecessors, adopting a retrograde lunar orbit that flies in the opposite direction of the moon's rotation.
Further, it's a race against nature. What cannot be ignored is that all the efforts, all the anxieties, all the difficulties have one goal, that is, to ensure the stable operation of Chang'e-6 in the orbit around the moon, accurate and successful landing.
If the situation is so grim and the countless challenges are so demanding, why does China still carry out the lunar exploration project without hesitation? There is only one answer, and that is that China, with its determination, courage and intelligence, hopes to leave its own footprints on the road of exploration of the universe. This undoubtedly reveals the tension and excitement of the challenge in scientific research.
Compared with the front side of the moon, the unknown and mysterious on the far side of the moon are more attractive. That's why China chose Chang'e-6 to land on the far side of the moon, and although 10 samples have been taken from the far side of the moon, no one dares to get behind it. Chang'e-6's magnificent mission is not just empty talk, but to prove that China is capable of stargazing on the blue road of the universe.
At the same time, Chang'e-6 is preparing to launch step by step, and it is also telling the world that China is not only staring at its own feet, but also staring at the sea of stars. Chang'e-6's orbital adventure around the moon is about to enter its most challenging part, that is, in the far side of the moon, where darkness and the unknown coexist, trying to find a precise landing site, which is waiting to be explored and discovered.
What will happen along the way, and how will the challenges be overcome?
2. Landing and Adjustment: Chang'e-6's Circumlunar Orbit Adventure
The journey of Chang'e-6 is not only a voyage through the universe, but also a retrograde challenge. Imagine what it would be like to suddenly change the direction of movement in an environment that we are accustomed to. Like in a giant spinning top, you'll need to steer yourself to keep your balance. Such a wonderful adventure is the challenge that Chang'e-6 is facing in front of you.
Landing on the far side of the moon requires the stable operation of the probe in orbit around the moon. For Chang'e-6, this requires a high degree of precision and stability, just like archery. Otherwise, it will not be possible to achieve accurate descent. It's just that what Chang'e-6 is facing is the rotation of the moon in an extremely complex inclination change. Although complex and full of challenges, Chang'e-6 is not afraid, because it is a battlefield and challenge that breaks the routine and proves its strength.
In addition, the adjustment before landing is a rigorous test. Because only a precise landing can allow the probe's journey to space to continue. Chang'e-6 needs to adjust its orbital plane to a coplanar position with the landing site, just like looking for a dance partner with precise coordinates on the endless cosmic stage, and every turn, rotation, or even a slight shift in the center of gravity may change future dance steps. But only after completing the adjustment of this dance sequence, Chang'e-6 can quietly settle on the far side of the moon and start a new round of space journey.
Despite the seemingly arduous appearance, Chang'e-6's orbital adventure around the moon is not over. In the pre-selected landing zone, the South Pole of the far side of the Moon, the Aitken Basin, not all areas are flat and require further verification. Finding a flat foothold in the midst of jagged mountains is a daunting challenge.
Despite all the difficulties encountered in preparing for the landing on the far side of the moon, Chang'e-6 demonstrated an indomitable and courageous spirit. As it enters the countdown to landing, we look forward to whether it will successfully land on the far side of the moon, and then complete the excavation mission in just 48 hours, and expect it to tell us more secrets about the far side of the moon.
3. The 48-hour final: the speed and efficiency of Chang'e-6
Imagine that on the far side of the vast moon, Chang'e-6 completed the task of excavating soil and sampling in just 48 hours. In that cold, sandy lunar land, every inch of progress, every grasp, there are difficulties and challenges. It's like a race, where the twin tests of speed and efficiency converge and become even more important.
Once the landing is successful, Chang'e-6's life clock begins to count down. The goal is clear: to complete the sampling within 48 hours, two ways, freehand and electric drill. The scenes that have been simulated countless times in my mind become reality at this moment, and every step of the action seems to have been rigorously choreographed and debugged. Like a delicate dance, Chang'e-6 integrates steps, movements, and body language to demonstrate its precision and efficiency on lunar soil.
Bare hands and drills, these two methods have their own characteristics, such as the gold right hand and the silver left hand. Freehand sampling is equivalent to digging lunar soil directly with "hands", and freehand sampling is preferred for places with relatively simple surface conditions. Chang'e-6's bare hands are like a magical little shovel, whether it is as hard as gravel or as soft as dusty lunar soil. Electric drill sampling, is suitable for complex landforms, may have deeper information in the area, it can work multiple times, each time not more than 2 meters deep, the excavation volume is larger, for the deep research of scientific research is of far-reaching significance.
Despite the rush of time, Chang'e-6 has found a delicate balance between the flexibility to change sampling methods and the guarantee of speed and efficiency. The balance of getting the most samples in the shortest amount of time without sacrificing the quality and validity of the samples is also an art.
Chang'e-6 was the clear winner in the final of speed and efficiency, demonstrating to the world China's determination to strive for excellence in space technology with its extraordinary resilience and determination. This final is not over, and there are many things to be done, such as, how to return the collected samples to Earth? How will Chang'e-6 continue to explore and discover more secrets on the far side of the Moon?
4. Global Sharing: The Spirit and Commitment of China's Aerospace Industry
China's Chang'e-6 has once again demonstrated its pace towards international cooperation. In today's entire aerospace field, China has entered a new era of "joint cooperation", facing the world, and any country can cooperate with China under the premise of meeting certain conditions.
This international collaboration has already shown new possibilities in the Chang'e-6 project, leading to a future of mutual support and sharing of scientific research results.
In April this year, China announced the applications of 10 scientists from six countries, and obtained preliminary approval for borrowing Chang'e-5 lunar samples, which is also a practice of China's aerospace industry to promote scientific research sharing and cooperation with a global sharing attitude.
Recently, Richard de Gris, a professor at Macquarie University in Australia, predicted that the samples collected by the Chang'e-6 mission are expected to be shared with the international community, demonstrating China's global vision in the field of space.
Sharing exists in lunar exploration, but it also appears in the scientific cooperation between Mars exploration and China's space station. China's space industry has become a model of international cooperation, embodying the spirit of openness and fairness, as well as the persistent pursuit of far-reaching research and common exchanges with mankind.
It is important to know that every lunar sample is extremely precious, they may reveal secrets about the evolution of the moon and the entire universe, may represent the exploration of new materials, new energy, and may even expand our understanding of the unknown world. Faced with this precious resource, China did not take it for itself, but chose to share it with all mankind. This is undoubtedly the perfect embodiment of China's aerospace broad-mindedness and responsible spirit.
Epilogue:
At the same time, China's aerospace industry should not only share its achievements, but also strengthen its cooperation with the global aerospace field and jointly explore ways to achieve a harmonious universe. After all, the goal of China's aerospace is not limited to the moon and galaxies, but hopes to promote the progress of human society and promote global scientific research exchanges and cooperation through space exploration.
This concept runs through China's aerospace industry, giving it incomparable soft power and setting a model for the global aerospace field.
So far, the wonderful journey of Chang'e-6 can be said to be a perfect short slice, demonstrating China's aerospace firm determination, innovative spirit and great love to contribute to global scientific research in chasing the dream of space.
