Vol 6 Chapter 3254: embark on the road home
Latest website:
So from this we can see how low the moon's gravity is, which is why it is not as good as Mars. Of course, it's also because Mars is larger than the moon.
The equatorial diameter of Mars is 6,790 kilometers, its volume is 15% of the Earth's, its mass is 10.8% of the Earth's, almost one-eighth, and its surface gravity acceleration is 38% of the Earth's.
As for the moon, its equatorial diameter is 3,479 kilometers, and the volume of the earth is almost 49 times larger than it. The mass of the earth is approximately 81 times the mass of the moon.
So in comparison, the moon is much smaller. Because its mass and volume are too small, the gravitational force it can generate is relatively small. Plus, there is a huge earth next to it, so it naturally cannot maintain an atmosphere.
Of course, although the moon is said to be a vacuum environment, it actually still has a weak atmosphere, but it is very weak and almost non-existent.
Haoyu Technology Linghu Headquarters Park, Xinyuehu Aerospace Command and Control Hall.
Wu Hao and the others gathered together to witness that the return-type lunar experiment unmanned spacecraft landing ascender, which already carried the gold meteorite core and lunar resource samples, was about to take off from the moon and embark on the road home (return to the earth).
The atmosphere in the hall is tense and full of expectations. Through the huge screen in front of the hall, you can clearly see the real-time picture of the return-to-lunar experiment unmanned spacecraft.
As before, Wu Hao, Zhang Jun and Lin Wei were all sitting in the guest seats, their eyes fixed on the screen, and their hearts were filled with tension and anticipation.
This is a critical moment, and any oversight may lead to mission failure.
Yu Chengwu stood in front of the podium, his eyes firm and decisive. He always pays attention to the status of the spacecraft and the collaborative work between various departments. He knows very well that as the general person in charge, every decision he makes is related to the success of the entire mission.
Zhou Xiangming was concentrating on monitoring various parameters of the spacecraft. His fingers were tapping rapidly on the keyboard, entering data into the computer for analysis. His eyes were full of concentration and calmness, as if he had become one with the spacecraft and could sense every subtle change in it.
As the system countdown ended, bursts of dust rose from the bottom of the landing ascender. Like a huge silver butterfly, the landing ascender broke free from the embrace of the moon and slowly rose into the sky.
Because the moon has no oxygen, the huge bright tail flame emitted by the engine on the landing ascender cannot be seen. But through the high-definition camera, it can be seen very clearly that these engine nozzles are ejecting high-speed particles, just like dust.
This is the ashes ejected from the burning fuel. Relying on them, the landing ascender can escape the moon's gravity and climb upward.
The landing ascender drew a graceful arc in the sky, and its elegant posture formed a sharp contrast with the vicissitudes of the moon. Its speed gradually increased, and soon it passed through the moon's thin atmosphere and entered the dark space of space.
The orbital thruster waiting in orbit is like a lonely star, hanging quietly in the universe. Its surface reflects the sun's rays, giving off a charming glow. As the ascender gradually approached, the relative speed between the two became faster. The landing ascender was like a meteor, piercing the night sky and speeding towards the spacecraft.
At the moment when the two were about to come into contact, the engine of the landing ascender roared again, and it made its final maneuvering adjustment to ensure that it could dock with the orbital thruster accurately. Under people's nervous gaze, the docking ring of the landing ascender fit perfectly with the interface of the orbital thruster, causing the images of the orbiting thruster and the landing and ascender's extravehicular camera to shake and freeze.
After the docking was successful, the entire landing ascender and orbital thruster together formed a returnable lunar experiment spacecraft assembly, which began to slowly adjust its attitude to ensure that it could operate stably on orbit.
At this moment, the entire universe seemed to be shaken, and human wisdom and courage once again left a deep imprint on the universe.
In the Xinyuehu Aerospace Command and Control Hall in the Linghu Headquarters Park of Haoyu Technology, people burst into warm cheers. Yu Chengwu and Zhou Xiangming high-fived excitedly, their faces filled with excited and proud smiles.
This ascending and docking process can be said to be one of the most important and key actions in the entire journey home, and it is also a difficulty. Overcoming this difficulty means that the returnable lunar experimental spacecraft assembly will officially embark on a journey back to Earth.
Wu Hao, Zhang Jun and Lin Wei also smiled when they saw this, and they were sincerely happy for Yu Chengwu and Zhou Xiangming.
Because they know that behind this success lies the sweat and efforts of countless people, scientific research and technical personnel such as Yu Chengwu and Zhou Xiangming, and even the entire project and all employees of Haoyu Aerospace Co., Ltd. have sacrificed a lot for this moment.
Therefore, such success is deserved and logical. Only such success can repay everyone's efforts and hard work for such a long time.
Of course, this is only the first difficulty in returning home, and it is only the successful docking with the orbital thruster from the moon into orbit. UU Reading www.uukanshu.net The journey home has just begun.
The atmosphere in the entire Xinyuehu Space Command and Control Hall gradually relaxed, and everyone began to talk to each other, sharing their joy and expectations for the success of this mission.
However, they did not relax their vigilance. They know that although the spacecraft has successfully taken off, the process of returning to Earth is also full of challenges and uncertainties. They must continue to be vigilant to ensure that the spacecraft can return to Earth safely.
Because of the earth's gravity, it is easier to transfer from the moon's orbit to the earth's orbit than before. It not only consumes less fuel, but also takes less time.
Even so, there are still many unknown risks during the spacecraft's return to Earth. Yu Chengwu and the others need to pay close attention to the dynamics of the spacecraft, although the entire return process is still controlled by the intelligent control system carried by the spacecraft itself. But Yu Chengwu and Zhou Xiangming still have to pay attention to the status of the spacecraft, especially the operation of each system, and be ready to take over at all times.
Once there is a problem with the system, they will immediately take over the remote control to command the spacecraft to continue returning to Earth.
Fortunately, the intelligent control system of the spacecraft performed very stably. After dozens of hours of flight and orbit changes, the spacecraft finally reached the earth's orbit.
This means that this returnable lunar experimental spacecraft has reached the final stage of its journey home, and the only step left is to return to the atmosphere and land.
And this process is also the last and most dangerous step in the entire journey home. Success or failure depends on this, so the entire Xinyuehu Space Command and Control Center once again filled with a tense atmosphere. (End of chapter)
