It took them nearly a week or so to drag the asteroid to the moon's orbit.

After all, such a big asteroid, the Ming Empire is not allowed to enter the earth's lunar orbit, this is the Ming Empire's long made space safety regulations, once an asteroid or meteorite with a diameter of more than 50 meters enters the earth's lunar orbit, it will immediately be warned by the Ming Empire's Universe Management Center, and will also be revoked Spacecraft driving qualifications, so they can only be near the lunar orbit, but now the lunar orbit is not empty, For example, the place where they are now is planned by the Ming Empire as a cosmic ore trading center, and there is also a small space city here, this space city is less than 10,000 meters in diameter, and the permanent population on it is not very large, and most of these people are ore buyers who are stationed here from those smelting metal manufacturers.

When their ship arrived, he saw the same spacecraft as their spaceship, and most of these mining ships were dragging various ores large and small in the back.

Just when they were approached by the ship, they saw a small spacecraft the size of a car flying in the distance, this kind of spacecraft is actually the smallest means of transportation between spaceships and spaceships in the Ming Empire in space, the smallest of these spaceships is only more than three meters long and one meter wide, and the largest is only about ten meters, because once it exceeds ten meters, then it does not belong to the spaceship.

The spaceship approached the mine ship and asked to communicate with them.

The four brothers had never experienced this situation before, so they were still a little confused, but they still agreed to each other's communication requests.

"Hello! I am a staff member of the center, my name is Deng Cong.

That's right, to enter the Space Ore Trading Center, there must be inspectors from our trading center, who will analyze the ore you have mined to determine the composition of the ore, and then the ore will be registered, and after the registration is completed, it will be done.

If someone needs it, they can see the information of the ore you are stepping on from the trading platform of the trading center, and then someone will buy it directly from you, of course, if there is an ore that has not been sold for a month in the trading center, the official will evaluate it according to the composition of the ore, and then the official will recycle it. And I'm here to test the minerals for you. The staff named Deng Cong said.

"Okay, we got it, thank you." As the eldest of the four brothers and the captain of the Five Brothers, he replied.

The ore detection was very fast, such a large piece of ore, including the other three pieces in their spaceship, was detected in less than ten minutes, and then they drove the space mining ship into the trading center.

……

The discussion on the Moon's Mars transformation plan continues, after all, the Mars transformation is a very large project, so the most detailed planning must be made.

And Zhu Lei has also been staying on the moon during this time, but he is not completely on the moon for the discussion of the Mars transformation plan, and the discussion may last 1 to 2 years, he can't stay there every day for such a long time, you just have to go there from time to time.

In fact, the main reason for staying on the moon is that Zhu Lei's Yongan Group is ready to start the next goal of the space program, which is to further explore the Kuiper Belt of the solar system and the places outside the Kuiper Belt, so as to prepare for the next step of the Ming Empire's exploration of Proxima Centauri, the nearest galaxy in the solar system.

Because now the first controllable nuclear fusion reactor of the Ming Empire is about to be completed, so mankind will soon enter a new space age, so in the near future, long-distance space travel is no longer a dream for the Ming Empire, and the fastest spaceship that can be manufactured with the current technology of the Ming Empire can reach about 10% of the speed of light, and it only takes a few decades for such a speed to reach Proxima Centauri. And a few decades is nothing to the current life expectancy of the Ming Empire.

Before detecting Proxima Centauri, the Ming Empire must complete a detailed survey of the entire solar system and its surrounding environment, and from now on, arm the entire solar system, after all, the current space strength of human beings is still too weak, especially the early warning ability.

With mankind's current space military early warning capability, even if the enemy really reaches the edge of the solar system, more than 80% of the human race may not be able to vent, after all, human beings have a warning radar at the edge of the solar system, and all the warning forces are provided by the earth's own territory.

The various warning radars on the earth, as well as various space telescopes, can only warn the eight planets of the solar system at the farthest, that is to say, when the enemy arrives near the solar system, human beings will not be able to find them at all, so once the enemy enters the solar system, in fact, it is already very passive for human beings, even if the war is finally won, then human civilization will be hit very hard.

After all, the cosmic war is fought at one's own doorstep, and it is very likely to affect the home, so human beings must master the feeding situation of the solar system, and human beings must also arrange various warning radars in the periphery of the solar system, as well as space telescopes every move outside the solar system, and even if there is time, various defensive weapons will be installed in the Kuiper belt of the solar system, only in this way will the safety of the entire solar system and the safety of human beings be guaranteed to a certain extent.

Therefore, due to the smooth implementation of the asteroid belt mining plan, the Ming Empire will no longer lack all kinds of metal minerals in the future, and the controllable nuclear fusion technology has made a breakthrough, so the vigilance system and defense system in the outer periphery of the solar system do not have to worry about the lack of energy, and the controllable nuclear fusion technology can provide enough energy for these defense systems and vigilance systems.

In fact, Zhu Lei's Yonghuang Group has sent a number of space probes to conduct a preliminary survey of the entire solar system, but because these probes are all unmanned probes, and these probes are products from a few years ago, they are already very backward compared to now, and some of these probes have not even reached the periphery of the solar system, so the data collected before are very simple.

And because these detectors are generally small in size, the technology is relatively backward, and the speed of the detectors is also very slow, so the data collected is still very limited.

So Zhu Lei and they recustomized the solar system exploration plan, the biggest difference between this plan and the previous launches of the probes is that this time his Yongan Group plans to use a manned spacecraft and unmanned probes to explore the solar system.
