Their mission is to spread their wings and dance around the moon, writing a new chapter in China's aerospace in the distant space.
However, just at the critical moment when the satellite was about to reach the orbit of destiny, an accident disrupted all plans.
The failure of the launch is not the end of victory or defeat, but the prologue of a new story. The story of these two moons is like the phoenix in ancient Greek mythology, rejuvenated from the flames of frustration.
How did the 220,000-kilometer space solo dance ignite new hope in a desperate situation through a series of self-rescue measures? What mysterious force guided them to shake off their shackles and rush to the embrace of the moon? Why do satellites have to control DRO orbits, and what kind of grand dream of stars does this space mystery relate?
This is not just a technological leap, it is China's unyielding spirit and a demonstration of the desire to explore the boundless universe.
Come, let's walk together into this suspenseful resurrection journey across space.
【Hanging Hope - Rekindling the Dream of Lunar Exploration】
Dreaming of the Moon: China's Satellite in Search of the Moon
Our story begins on March 13, 2024, at the Xichang Satellite Launch Center, where China is determined to adopt a strategy of flying two arrows together, shooting not only satellites to the deep space of the moon, but also the indomitable will of Chinese to explore space.
DRO-A and DRO-B satellites, two names that will go down in the annals of China's space history, symbolize the ambition and ambition of China's space industry.
On this day, with the powerful rocket thrust, everything seems to be moving towards the right trajectory in space.
An unexpected challenge: self-redemption in the storm
But in the journey of space exploration, there are always variables. The remarkable orbiter and rover had not yet set foot on lunar soil, but the two satellites suffered a setback at the critical moment of launch.
Yes, we all know that the launch was a failure.
However, on the vast stage of space, the satellites DRO-A and DRO-B have not been disgraced, and they have begun an incredible journey to save themselves.
In the detailed analysis of the ground control center and the majority of astronauts after the fact, this self-rescue was regarded as a pioneering feat in China's aerospace history.
Struggles in the face of adversity: the orbital dance of two satellites
In the original plan, the two moon-orbiting satellites were supposed to reach an elliptical orbit with a perigee of 525 km and an apogee of 132577 km.
However, the results of the satellite's self-rescue were impressive, successfully lifting to a wider latitude orbit of 971 km at perigee and 225193 km at apogee.
This means that they do not need the assistance of external forces, relying on their own power systems and abundant fuel, to launch a gorgeous retrograde dance in the darkness of space.
The Fuel of Faith: The Birth of China's "Phoenix Satellite".
These two satellites have lost the help of launch vehicles, but they have not lost the wisdom of the expert team and the determination of China's aerospace industry.
As the orbit continues to rise, what technology has enabled DRO-A and DRO-B to achieve such amazing self-resilience? This unfinished topic is attracting the attention and discussion of space enthusiasts around the world. What amazing self-control and navigation systems do they have, and what engineering marvels do they contain?
And all these efforts are aimed at reaching a fantastic existence—the DRO orbit.
This orbit has truly become a new target in space exploration, a mysterious and desirable location, a long-distance retrograde orbit around the moon, and it will be the next important node in China's space exploration program.
【The Significance and Challenges of Striving in the Interstellar-DRO Orbit】
Exploring the "Green Channel": The Ultimate Goal of Satellites
"DRO" orbit, a term that has attracted much attention in the aerospace industry, represents not only a trajectory, but also an endless hope for the future of space travel.
It is a high orbit with a lunar orbit radius of about 61,500 km, making it an ideal springboard to the moon. The journey of the satellites DRO-A and DRO-B is to reach this new realm, which no one has ever set foot in before.
But why is it "DRO", is this the world-famous "green channel"?
The mystery of the long-distance retrograde orbit around the moon
The scientific significance of the "DRO" orbit, this route, lies in its stability and economy.
If the spacecraft flies along this orbit, there is almost no need for orbit adjustment. Spacecraft can save valuable power and extend mission timeliness.
Moreover, retrograde orbit is inherently convenient for spacecraft acquisition and entry, which will greatly reduce the complexity of lunar missions.
The scramble for the "space track".
Space, like the ocean, has its own shipping lanes and resources. Not only China is aware of the advantages of the "DRO" orbit, but the international space community has also set its sights on this route.
China's Chang'e-5 and the U.S. "Orion" spacecraft are actually carrying out space journeys around this orbit.
Space powers compete in every inch of space, and the predetermined orbit not only ensures flight safety, but also represents the prospect of the development of space resources.
The unique strategic significance of space orbit
It is undeniable that at the boundary of space exploration, every newly opened shipping lane means the possibility of human beings expanding further into space.
The "DRO" orbit may become a transit station for manned missions to the Moon or even Mars in the future, and the door to a "new world" will be opened if any country takes the lead and which team digs deeper.
【Sinking Sand and Recasting - The Value of Success and Future Prospects】
The success of Chang'e-5: the unstoppable momentum of lunar exploration
While discussing the DRO orbit, we cannot ignore the iconic achievement of the Chang'e-5 mission.
The successful launch of this pinnacle of civilization in 2020 not only heralded a new era of China's aerospace in the world, but also laid a solid foundation of confidence for the DRO-A and DRO-B satellites.
Self-help in distress: the tenacity of DRO's moon-orbiting satellites
What is little known is that the DRO-A and DRO-B satellites are not the first "rebirth" of China's space industry.
The Zhongxing-9A in June 2017 is a miracle in the history of Chinese satellites.
In the face of the abnormal launch, the satellite ignited itself to lift the orbit, and after arduous self-rescue, it finally completed its mission in the predetermined orbit and became a real "star power" in space.
Looking Ahead: Networked Asterisms and the Dream of the Moon Landing
Now, we hope that the DRO-A and DRO-B satellites will repeat this feat, and bravely move towards the other side of the successful orbit with a higher starting point of the satellites.
Once realized, the grand picture of Samsung connectivity will become a reality, and together they will weave a gorgeous network in space to help the subsequent lunar exploration and even manned missions to Mars.
[Conclusion: The Departure of the Space Dream - A New Chapter of China's Aerospace]
In this starlight painting of space, every moon that rises bravely is a bright spot. They are not only the crystallization of technology, but also the witnesses of China's continuous space exploration.
Whether it is the precise navigation in the DRO orbit or the challenge of satellite self-recovery, every step shows the world China's courage to work hard and innovate in the space field.
The history of the struggle of DRO-A and DRO-B satellites may only be a shallow wave in the long river of space exploration, but it is precisely such waves that converge into the magnificent sea of China's aerospace industry in the future.
China's dream of lunar exploration has never stopped because of temporary challenges. The work of an astronaut is not only to start a rocket, but also to start a dream, to inspire a country, to inspire all mankind to advance into the unknown.
Therefore, we have reason to believe that in the near future, the DRO-A and DRO-B satellites will become the pioneers of exploring the colorful world of space, just like the ancient navigators who landed in the New World.
Let us wait with bated breath to see how they will write their own history and how they will create a new milestone for China's aerospace industry.
