Chapter 1624 "Christmas News"

But Li Jian only made such a start, and then did not explain it, but continued: "In fact, when we conducted flight tests, we experienced tens of thousands of failures, but after each failure, our team would gather together to solve the problem.

Twenty hours before the launch, the lunar rover and other equipment in the lunar module were already charging. The lunar module weighs 11 tons and is more than 8 meters tall. It can be said to be an absolute big guy among all the lunar landing projects in the world. Moreover, it is not only the heaviest space probe in the world, but also the one with the most complex system.

This probe has a total of There are five parts, from bottom to top, starting from the part that docks with the rocket, which are the orbiter, the returner in the belly of the orbiter, the lander, and the cargo hold, and the ascender and some special equipment on the top.

The lunar exploration mission involves the relative relationship between our blue planet and the moon. In fact, there are only 5 days in the whole 1026 years to meet such conditions, including the launch location, which determines the most appropriate time for the rocket to launch.

The core of this mission, the sampling project on the back of the moon, also has only a few days to complete due to time constraints. No matter how much remaining energy the lunar module has, no matter how much ... No matter how many samples are stored in the cargo hold of the lunar module, the ascender of the lunar module must ascend within the planned standard time and dock with the orbiter that has been orbiting the moon, so that the samples collected by the lunar rover can be successfully put on the shuttle bus back to our blue planet.

For this lunar sample collection, we chose two methods, one is to drill with the drill of the lunar module and the lunar rover, and the other is to use the lunar rover's picking equipment to collect samples from the surface.

Specifically, drilling is to drill into the range of two to six meters deep on the lunar surface to collect samples. In this process, the drill equipment can obtain samples from different lunar surfaces to different depths below the lunar surface. lunar soil, lunar rocks and possible metal substances.

Surface sampling is to shovel soil and dig ice on the lunar surface. In fact, the lunar sample surface sampling technology all comes from the sweeping robot technology of our Jiuzhou Technology Titanium Star Department. After years of exploration and optimization, our company's sweeping robot has become a powerful smart home product that integrates sweeping, mopping, air purification, liquid treatment, pollutant treatment and other cleaning-related tasks. At the new product launch conference a week later, there will also be a sweeping robot using new technology on display. "

Li Jian may be the first aerospace engineer to advertise in the morning news column.

What he said was not off topic, and after this sentence, he also talked about the most important content.

"The former polar bear successfully drilled and brought back lunar soil from the moon using an unmanned probe, weighing more than 300 grams. NASA brought back 382 kilograms of lunar soil samples in the Apollo program, and Chang'e 5 of Daxia Aerospace Group brought back 1.731 kilograms of samples.

When the engineers of Daxia Aerospace Group communicated with us before, they mentioned a special situation, that is, we should not limit the weight and volume of the calibration sample collection too much, because when they designed the project, they referred to the lunar soil density disclosed by NASA, so they designed a 2-kilogram mission standard, but when the lunar module landed on the moon and began to collect samples, they found that the information disclosed by NASA was wrong, and the actual lunar soil density was smaller than it was disclosed. Therefore, under the same volume, the mass was reduced, and 2 kilograms became 1.731 kilograms.

Fortunately, we believed in the engineering team of Daxia Aerospace Group, and when designing the Jiuzhou lunar module, they left enough margin, so this time we Jiuzhou The lunar exploration project brought a total of 5 kilograms of lunar samples to Jiuzhou Technology.

The sampling process is also based on the lunar environment data provided by engineers from Daxia Aerospace Group, because in the process of autonomous sampling by robots, the program needs to test and learn the lunar environment, and then the lunar module and lunar rover can better complete the task.

Carbon-based chips have performed extremely stably in this mission, so in the future, Jiuzhou Technology will use carbon-based chips as aerospace first-level technology and will not open carbon-based chip technology to ordinary cooperative enterprises. "

5 kilograms of samples, even when the reporter heard the sample data, he was very surprised and asked: "This should be the moon landing mission with the most samples collected by all aerospace agencies on Blue Star. How will these samples be handled next?"

When Li Jian heard this pre-arranged question, he knew that the time for his company to advertise had passed, and he had to "read from the script" next.

"The company's processing of lunar soil can be divided into three parts and three uses.

The three parts are that most of the samples will be placed in our Jiuzhou Technology research base in Xinke District, Daxia Rongcheng, for scientific research. Another part will be donated to the Daxia Academy of Sciences Observatory and Daxia Aerospace Group to thank them for their selfless help. In addition, a part of the processed lunar rocks will be stored in Hunan Shaoshan.

As for the three uses, the first use is also the most important use, scientific research. The lunar samples we collected this time include lunar soil, lunar rocks, lunar ice, and a small number of metal minerals and special substances. Of course, we have only completed the classification of 3 kilograms of samples, and there are still 2 kilograms of samples left. I don’t know how many surprises we will get.

The second use is that part of the processed lunar soil will be placed in the Daxia Museum, Rongcheng Museum and Jiuzhou Museum, so that all scientific researchers and ordinary tourists can enter the museum and observe the real objects of another planet up close, instead of looking at photos and videos.

The third use is that we, Jiuzhou Technology, will donate part of the lunar soil to cooperative enterprises and institutions in accordance with international conventions and previously signed cooperation agreements, to help partner enterprises and institutions understand the differences of the moon more quickly, help them develop aerospace technology, and cultivate aerospace talents. "

This is Jiuzhou Technology's arrangement for lunar samples. In general, it is basically the same as the way Daxia Aerospace Group handled it before, but the specific implementation details are different.

At the end of the news, the host read the content of a poem: "Thirty-eight years have passed, and it's just a snap of the fingers. I can reach the moon in the sky, I can catch turtles in the five oceans, and I can return home with a triumphant smile. Nothing is difficult in the world, as long as you are willing to climb. "
