The successful landing means that the launch mission of the lunar cargo transportation system is a complete success. It also represents that Haoyu Aerospace’s lunar exploration and the construction of the lunar scientific research station have officially entered the first step and ushered in a good start.

For the staff of the entire lunar cargo transportation system spacecraft project technical team, they can finally breathe a sigh of relief and have a good sleep.

Since the launch of the lunar cargo transportation system, the staff of the entire project technical team can be said to have not had a good night's sleep. They have been staying at their respective posts every day to prepare for any positive situations that may occur.

You know, this 380,000 kilometers is not a short distance, and it involves going from one planet to another, involving gravity escape, gravity capture, deep space maneuvering, deep space steering, and deceleration and braking. , orbiting and orbiting, and a series of technical issues, every link is crucial.

Although there have been two previous successful cases, this time is different, because this time both the lunar cargo transport system spacecraft and the cargo carried are more than ten times that of the previous ones, so the difficulty can be imagined.

So at this moment, you can imagine the mood of the entire project technical team members. Wu Hao, who was also a technician, naturally understood their mood at this time and also expressed cordial condolences to the team members.

After the landing is successful, follow-up work will proceed steadily, but there will definitely be no big moves tonight. Having just completed such a difficult task as landing, I need to take a breather.

So after expressing condolences to the staff in the hall, Wu Hao and the others immediately prepared to leave, but unfortunately, he did not leave because the reporters, bloggers and anchors outside had not dispersed yet, waiting for Wu Hao and the others to show up. Woolen cloth.

Faced with this situation, Wu Hao had no choice but to bring Yu Chengwu, Zhou Xiangming and others to appear in front of the reporters. As soon as he appeared, he was surrounded by this group of people.

Mr. Wu, Mr. Wu...

At this time, Yu Chengwu, who was standing next to Wu Hao, stepped in front of Wu Hao. While protecting Wu Hao, he said to these reporters: "Dear journalists, please be quiet. Please consciously maintain the order of the scene and ask questions in an orderly manner. "

Mr. Wu, how are you feeling now?

After hearing Yu Chengwu's words, the scene immediately fell silent. Before anyone could speak, a female reporter standing in front asked.

Wu Hao smiled softly when he saw this: "Of course I feel better. This is a great victory for us in the aerospace industry, so we should be happy."

"Mr. Wu, does this successful landing on the moon mean that the construction of the lunar surface scientific research station can be officially started?" Another male reporter saw that he had finished his words and asked hurriedly.

When other reporters saw this, they could only look at this reporter helplessly, and then looked at Wu Hao to wait for his answer.

Wu Hao nodded slightly when he heard this and said: "That's right, the goods we transported this time are basically used for the construction and preliminary preparations of the lunar surface scientific research station.

But this does not mean that the construction of the lunar surface scientific research station will start immediately. First, we need to carry out a series of preparations. For example, building and deploying a series of other basic support facilities, such as communication base stations, solar power stations, deploying and debugging multi-purpose engineering robots and intelligent control robots, debugging lunar soil 3D printers, etc.

After all the preparations are completed, we will also strengthen the foundation required for the building. Only when these preparations are completed, can the construction officially begin.

We know that building the foundation of a house is the most important, and the same is true for this lunar scientific research station. The surface of the lunar soil is relatively fluffy. If there is no solid foundation, the built house may have problems such as tilting and subsidence, seriously affecting the quality of the building and endangering the safety of people living in the building.

In addition, everything this house needs, such as water, electricity and electricity network, is required. On the moon, each of these is crucial.

For example, electricity, as everyone knows, all the home appliances we currently use are powered by electricity.

Electricity is probably the best solution here. Although it is said to be easy to solve, it is also difficult to solve this problem on the moon. First, we have to transport many solar panels to the moon. Solar panels may not be expensive, but the freight from the earth to the moon is very expensive. To drive the operation of such a large scientific research station, the solar panels required are calculated in tons.

Secondly, everyone knows that one day on the moon is roughly equivalent to about twenty-nine days on the earth, which is about one month on the earth. Among them, the daytime on the moon lasts about fourteen days, and the night also lasts about fourteen days.

We know that the temperature difference on the moon is particularly large. During the day, when the sun is directly shining, the maximum surface temperature of the light-receiving surface can reach 150 degrees. Such high temperatures are certainly suitable for power generation, but they also pose a huge challenge to power generation materials.

At night, the lowest temperature can reach more than 180 degrees below zero, and even in some shadowed craters or canyons, the lowest temperature can reach more than 230 degrees below zero.

Such a hot and cold situation has extremely strict requirements for all materials. Even if it is as hard as rock, it has disintegrated and disintegrated into grains of fine sand under the moon's hundreds of millions of years of temperature difference between day and night.

Therefore, electricity is very important on the moon. With electricity, we can use electricity to insulate all equipment and facilities to ensure that they can survive such a cold winter. The reason why our "Yuetu-1" malfunctioned was that it could not withstand the cold winter of the moon.

The day and night on the moon last longer, and solar panels can be used to generate electricity during the day, but at night, solar panels cannot generate electricity, so where should the electricity come from. "

Speaking of this, Wu Hao paused, glanced at the reporters gathered in the front row, and then continued: "In this case, there are generally two solutions. The first one is to use an isotope thermoelectric generator. Power generation is also the most mature technology used in Europe and the United States, especially Laomi space probes. Using this technology, these probes do not need to be afraid of nights and winters, or even dust storms on Mars.

However, this isotope thermoelectric generator also has its disadvantages, such as high technical difficulty, radiation, and limited power generation. It's okay to maintain one detector, but it's definitely a bit stretched to maintain a huge scientific research station. "

At this point, Wu Hao changed the subject and smiled: "At this time, some people may say, why not just transport a nuclear power plant up there? Isn't there so much helium-3 on the moon? This will solve all the problems."

Ha ha ha ha……
