In the live broadcast room of the main station news channel, relevant experts were specially invited to live broadcast the entire transfer process. These two experts are already very familiar to everyone. They are Director Zhang and Professor Huang who were invited during the last launch mission.
The two of them were very emotional to be invited back to the live broadcast room to host such a program. They did not expect that in just a short time, the second lunar cargo spacecraft would be launched.
"Professor Huang, after more than a year, you once again saw the Jianmu-9 heavy-lift rocket lifting the lunar cargo spacecraft for transportation. How do you feel now." The host first asked Professor Huang.
When the host asked, Professor Huang responded with a smile: "Of course I am very happy, very excited, and very emotional.
To be honest, I never thought that a private enterprise like Haoyu Aerospace could go so far, so fast, and so well in this field. They have done things that many countries and companies have not been able to do for decades. This mission is not only a grand event for Haoyu Aerospace, but also a grand event for our entire domestic aerospace system and even our people across the country. "
"You just used the words far, fast, and good in succession, and expressed your excitement and joy. It can be seen that you are indeed very excited. Why, isn't this just an ordinary launch mission? Why did you behave like this? So excited and emotional. What is the difference between this mission and the previous mission, or what is the highlight?" The host asked continuously.
After listening to the host's words, Professor Huang laughed: "Yes, I am very happy and gratified. I am gratified that an aerospace enterprise like Haoyu Aerospace can emerge in our country. Although it is only a civilian aerospace enterprise, it has achieved so many achievements." The results are no worse than our aerospace system.
And it has developed very rapidly. It has only been a few years since the successful launch of its first carrier rocket until today. They have already been able to land on the moon and establish a scientific research station on the moon. This is something we have never thought about in the past. I dare not think about it.
So before the show started, I was still sighing with Director Zhang. We are all satisfied to be able to see these in our lifetime.
Director Zhang was persuading me to live a few more years, and maybe I could see more exciting things. "'
Hehehe...
Director Zhang and the host both chuckled after hearing Professor Huang's words. Professor Huang continued to speak with a smile: "This is the second lunar cargo transport spacecraft launched by Haoyu Aerospace. Compared with the first lunar cargo transport spacecraft, this lunar cargo transport spacecraft is particularly critical because it has It is equipped with a large-scale 3D printer that will be used to print the lunar scientific research station.
This printer is very critical. It will undertake the overall printing work of the entire lunar scientific research station. And it is said that the printing efficiency is very high. If everything goes well, the entire main body will be completed in about half a year, which was unimaginable in the past.
You must know that the total construction area of the first phase of the lunar scientific research station announced by Haoyu Aerospace reaches more than 500 square meters.
We know that it would take several hours to build such a house of more than 500 square meters on the earth, let alone on the moon. This speed is not unpleasant. "
"Yes." Director Zhang on the side couldn't help but said: "We were shocked when we first heard that Haoyu Aerospace announced this time plan. We thought we heard it wrong or that Haoyu Aerospace announced it wrong. .After repeated verification, it was officially confirmed that this time period is correct.
Therefore, we are all very confused and curious. Why is Haoyu Aerospace so confident that it can print out the entire lunar scientific research station's main building body of more than 500 square meters within half a year.
Therefore, with curiosity and doubts, and in line with the purpose of serving the enterprise, we formed an expert inspection team and went to Haoyu Aerospace to conduct a practical inspection. The focus of the inspection was to demonstrate the technical feasibility of Haoyu Aerospace on this project.
As a member of the inspection team, I participated in the entire process. To be honest, it gave us a very shocking feeling. "
"Shocked?" the host couldn't help but ask.
Director Zhang nodded and said: "Yes, it's shocking. We never expected that such a private aerospace company would have such a high technical level. Many of the advanced technologies we saw during this period were eye-catching, even Let out an exclamation.
In the process, we finally saw the engineering prototype of this large-scale lunar soil 3D printer that will be sent to the moon. "
"What kind of printer is it? Can you describe it to us?" the host couldn't help but asked curiously.
Director Zhang said with a smile: "Actually, it is similar to an ordinary printer, except that its design is more sophisticated and consists of many parts. Each part can be disassembled separately for repair and replacement, thus making it easier for the entire printer to be used on the moon. Perform maintenance and repairs.
In order to verify the reliability of this printer, the project R&D team built a surface environment sandbox in a huge indoor space. The "lunar soil" in the entire sand table is sandy soil that we simulated and mixed based on the lunar soil samples collected by several previous lunar exploration missions, as well as the lunar soil components previously detected by Haoyu Space on the moon.
It is said that the project research and development team mixed the sand found in several deserts and rivers in a certain proportion to restore the composition and state of the lunar soil as much as possible.
And in order to simulate the real lunar environment, the entire lunar environment sand table is separated by huge glass, and a vacuum is extracted inside.
Then the lunar 3D printer was put inside for experimental printing, and we also watched its actual printing demonstration process. "
"Oh, you have also watched its printing process in person." the host asked.
"Yes." Director Zhang nodded: "Its working principle is actually no different from our ordinary 3D printers. The only difference is that it can print lunar soil, that is, sand, into a hard building body.
In fact, to put it bluntly, the principle is very simple. It uses the sticky properties caused by the high-temperature dissolution of quartz sand in the sand. First, the engineering robot will excavate and collect the lunar soil, and then screen it to remove some coarse particles and large gravel.
Then pour the sun-dried fine lunar soil into the feeding port and flow into the furnace. Solar power is used to drive the electric furnace to heat the incoming lunar soil, dissolve the quartz stone and broken glass in the lunar soil, and then mix it with other substances. It is pumped to the printing nozzle for further heating, and then stacked and printed like squeezing out toothpaste, thus forming the main body of the building. "
