Chapter 3075: The mission of the lunar landing and return experimental spacecraft
After hearing what Yu Chengwu said, Wu Hao couldn't help but nodded. Yes, it is rare because of the difficulty, and it is valuable because of the scarcity. Otherwise, it would just be a relatively high-gold product.
A stone, or just a gold nugget, is far less valuable, and it is impossible for them to spend so much effort transporting this gold meteorite core back to Earth.
That thing failed? Zhang Jun couldn't help but ask.
Hearing Zhang Jun's words, Yu Chengwu glanced at Zhou Xiangming, then smiled and spread his hands and said: "Then what can we do? Although this is not what people want, adventure is always full of risks. Before this task is formulated,
From the beginning, we have already taken the consequences of failure into consideration.
So even if the mission fails, we can accept it. At worst, we have to start over again. The detection work must face failure. The golden meteorite core is there, and it cannot escape for a period of time, and others cannot dig it away, so we
It will be shipped back sooner or later.
Besides, even if the mission fails, it is not without gain. The journey of more than 1,400 kilometers is a challenge for our equipment and will help us further test these equipment in such a cruel and complex environment.
The performance in the detector will accumulate a large amount of data for our next step in the development of detectors related to extraterrestrial planets, which will help its research and development.
In addition, even if we cannot transport back this golden meteorite core, we can still transport some other things. Anyway, we will not return empty-handed.
Not to mention anything else, the lunar soil and samples collected along the way are very precious, and transporting them back is a very wrong choice."
Where is the lunar landing and returning experimental spacecraft now? Can you take a look? Zhang Jun asked immediately after hearing this, I am now interested in the lunar landing and returning experimental spacecraft that is about to be launched.
It's just outside your spacecraft test workshop, please lead me there. Yu Chengwu responded, and then led Zhang Jun and Xu Qing. We walked outside the glass corridor for a while, and finally arrived at a huge test workshop.
The test workshop is smaller than the following development workshops. The outside is white and very dim under the light.
Yes, the lunar landing and return experimental spacecraft is not very small under those two small parts.
That's because it needs to store less fuel before it lifts off from the moon and returns to the moon's orbit. There must be too much fuel to support it in flying.
In order to support it to fly again, the push-back system it uses is also a newly developed vector engine equipped under your lunar surface transfer spacecraft. It is not only more powerful in reasoning, but also more precise in thrust control.
.
Therefore, you can't see that the lunar landing and return experimental spacecraft behind you is small in size, but there are no small parts in the structure.
Outside the test workshop, there were a few spacecraft placed in total, including the Walker manned spacecraft and other satellite products. However, what caught our attention the most was not the unique lunar landing and return vehicle.
Experimental spacecraft.
Yes. Yu Chengwu smiled and nodded and said: "You are wrong. That lunar landing and return experimental spacecraft was developed by you based on the lunar cargo transfer spacecraft.
Before reaching the Earth orbit, it then went through a continuous orbit change to reach the return orbit, and then separated from the lunar landing site.
It looks very different from your lunar cargo transfer spacecraft. Wu Hao said.
Therefore, the goods transported by the lunar return experimental spacecraft from the earth to the moon are basically related materials and equipment that were exposed to the space environment, mainly related equipment and materials for use in lunar scientific research stations.
construction work.
After walking to the lunar landing and returning experimental spacecraft, Yu Chengwu smiled and introduced: "Mr. Wu, Mr. Zhang, that is not the lunar landing and returning experimental spacecraft."
At the front, it is no longer the metal frame used to fix the core of the golden meteorite.
As for your lunar landing and return experimental spacecraft, it is a two-way return spacecraft. It cannot transport cargo to the moon and then transport the cargo from the moon back to the earth.
As for the landing lunar module, it will continue to fly along the return orbit and wait for an opportunity to release the return landing device carrying the gold meteorite core. It will also use the miniature attitude engine under the return and landing device to reverse orbit and control its landing.
Accuracy.
It cannot be seen that in order to transport the golden meteorite core at that time, your lunar lander does not have a closed cargo compartment under it, but uses an open pylon to retreat.
But as you can see from the size, the lunar landing and return experimental spacecraft is much smaller than the lunar cargo transporter.
Here, you also carry small-purpose intelligent robots, Wangshu series exploration vehicles, and related parts and components needed for engineering transport vehicles and other materials.
Before that, the lunar lander will ignite and ascend, and will retreat and dock with the orbital resource module waiting under the lunar orbit. The orbital resource module will carry the lunar lander module back to the earth.
Like your lunar cargo transfer spacecraft, the lunar landing and return experimental spacecraft is divided into two parts, namely the lunar landing module at the bottom and the orbital resource warehouse above.
The size of the lunar lander below is much smaller than the lunar landing compartment of the Lunar Cargo Transport System, and the structure is not the same.
That is mainly because the lunar landing and return experimental spacecraft is to return to the earth from the moon, so its orbital resource warehouse is much smaller than that of the lunar cargo transfer spacecraft. This is also to be able to reserve sufficient fuel to ensure that it can
The spacecraft was transported back to the earth from the moon.
The orbital resource warehouse will use the added fuel to retreat and change orbit, plunge into the small atmosphere, and use the huge friction of the small atmosphere to burn up and consume it under the South Pacific.
These include related mechanical parts used in the construction of the Zhihai lunar surface scientific research station, as well as glass and other building material parts.
As for the landing part of the lunar module, its remaining fuel will be used to de-orbit, causing it to burn up under the southern Indian Ocean."
Zhang Jun and Xu Qing nodded when they heard this, and then looked at the full picture of the lunar landing and return experimental spacecraft in front of them.
Compared with the lunar cargo transfer spacecraft, the lunar landing and return experimental spacecraft is not very small. The smallest of them is the lunar cargo transfer spacecraft, which is a one-way spacecraft. It can only transport cargo to the moon.
Then it has completed its mission and can come back from under the moon.
Before those materials arrive on the moon, they will be disassembled, and then a metal frame will be used to fix the gold meteorite core. Then it will be lifted up and retracted to dock with the docking hole at the bottom of the lunar lander, and the bolts will be inserted and tightened to complete the loading.
