At present, this large-scale lunar soil 3D printer has begun to print floor tiles and lay them on the entire lunar scientific research station foundation and these connected roads.

The entire process does not require the movement of this large-scale lunar soil 3D printer. It only needs to print out the floor tiles, and then hand them over to these two multi-functional engineering robots for construction and laying.

In the last mission, Wu Hao and the others transported two multi-purpose engineering robots and an intelligent control robot to the moon. This is the main force in the early construction of the entire scientific research station.

In the future, larger and more powerful robots, construction machinery and related equipment will definitely be transported to the moon to participate in even larger lunar projects.

In fact, the entire construction work has always been open to the public. Except for Wu Hao and others who will announce the entire construction progress from time to time, relevant media, especially those heavy media and TV stations, will regularly ask them for relevant news footage.

The reason why the media is so enthusiastic is because Wu Hao and his lunar scientific research station attract a lot of attention, so the ratings of relevant news reports are very high.

So this also makes these media very keen to find relevant news reports. No, in the latest related video, the foundation construction of the research station has been completed, and the road construction on the foundation has been nearly half completed, so related topics It's on fire again.

The main station's International News Channel also specially produced a related special report and invited relevant experts to attend and interpret it.

"Mr. Cai, as the deputy chief engineer of the lunar exploration project, what do you think of the latest video released this time." The host looked at an old man with gray hair but still very energetic and asked.

Hearing the host's question, Deputy Chief Engineer Cai nodded, then looked at the video on the screen and smiled: "To be honest, the construction progress of the entire lunar commercial scientific research station is far beyond my expectations, so We were also very surprised when we saw the news today, we didn't expect their construction speed to be so fast."

After hearing the words of Deputy Chief Engineer Cai, the host smiled and said: "Can you explain to us what you said quickly? Because it seems to us that the construction of this project is very slow. It seems that the relevant construction has started a year ago. Project. In the words of many of our netizens, if there is no progress, it will almost become an unfinished project."

Hahaha, after hearing the host's words, the two experts present laughed.

Mr. Cai said with a smile: "In fact, in more than a year, after the Lunar Cargo-1 spacecraft landed, the small lunar soil 3D printer they carried, as well as two multi-purpose engineering robots and intelligent control robots were put in place. The foundation part of Aerospace's commercial scientific research station project on the lunar surface has already begun, and the entire project has been almost in progress for nearly two years.

In the eyes of many people, especially the general public, the past two years have been very long, but they have just completed the construction of the foundation tonight. This speed is really too slow.

But for those in our industry and those who know a little bit about deep space exploration and lunar exploration, this progress can be said to be very fast.

You know, they are on the moon 380,000 kilometers away from our earth. Although compared to the vast universe, these 380,000 kilometers may not be worth mentioning at all, but for the current situation of us humans and our human technology, Said, this is like a natural chasm, difficult to cross.

Let’s not talk about anything else. Let’s just say that we can count on both hands the number of countries and aerospace companies that have been able to reach the lunar surface so far.

There are only a handful of people who have the ability to carry out large-scale construction on the moon and build their own scientific research stations. Not to mention that this is the only one that has already started construction and has made progress.

Therefore, from this aspect, no matter how slow their speed is, every step and progress they take on the moon is creating human history and writing a new chapter in human exploration of the universe and the moon. "

After praising and affirming the achievements, Mr. Cai continued: "Technically speaking, the current progress and achievements are already very fast.

Why do you say that? Because this is the moon, not our earth. The environment on the moon is very harsh. One day on the moon is equivalent to twenty-seven days on Earth. During the day on fourteen days, the maximum temperature can reach 127 degrees above zero. There are still about thirteen days of darkness, and the darkness on the moon is very harsh, with the lowest temperature reaching minus 183 degrees.

Of course, the temperature is not the most critical, the most critical thing is the lack of sunlight. Then equipment that relies on solar panels for power generation will not be able to receive power replenishment, and naturally will not be able to work.

Although there are currently four radioactive isotope batteries, the power they can provide is very limited and cannot support the use of high-power equipment.

In addition, the temperature in the dark night of the moon is too low, which will affect the operation of related equipment, so it cannot work. Under normal circumstances, these devices will enter a sleep state at night, and will wake up and start up again after surviving the night.

This also means that we only work on the moon for more than half of the year, and we are unable to work for nearly half of the time.

Therefore, the two years on the moon are actually only about one year that can be used. "

At this point, Mr. Cai paused for a moment, picked up a remote sensing map of the lunar surface near Zhihai, and then continued: "In the one year available, they must first level the land, which is more than two thousand square meters. The lunar surface needs to be leveled, the raised mounds and scattered rocks on the lunar surface need to be eradicated, and then the scattered lunar craters within the entire planned range must be filled.

Then use these multi-purpose engineering robots to repeatedly crush and compact.

You can take a look at the two Earth satellite remote sensing maps I have. This is a satellite remote sensing map near the Lys Mountains in the northwest direction of the Lunar Sea. This is the map before construction. This is the satellite remote sensing map after filling and compacting. You can See the difference very clearly. "

Comparing the two satellite remote sensing maps, you can clearly see the difference. It turns out that all the large and small impact craters in this area have disappeared, replaced by a flat lunar surface, which has very large craters around it. the difference.

To put it simply, it is like a flat area suddenly appearing on the dotted surface, which is very conspicuous.

"The difference is very big. We can see that many circles on it, that is, all the craters have disappeared." The host said while looking at the satellite remote sensing map.
