However, although the Ming Empire does not have any good solutions for those relatively large asteroids now, after all, there are only these three spaceships that the Ming Empire can carry out long voyages.

But after all, there are not only those relatively large asteroids in the asteroid belt, most of the asteroids are still relatively small in size, so they came to investigate the asteroid belt this time, and when they are ready to go back, they will bring some relatively small asteroids back for research and analysis.

Just when the captain of Explorer 2 was thinking about this, the data of those satellites launched by the Explorer 2 spacecraft came, and the data sent back by the aliens this time was actually one of their main goals to explore the asteroid belt this time, after all, whether it is to modify Mars or Venus, we must consider using asteroids to impact, and the source of asteroids is only two places in the entire solar system.

One is the asteroid belt between Jupiter and Mars, and the other is the Kuiper belt, which is the only place in the solar system where asteroids or dwarf planets that modify Mars and Venus exist.

However, the Kuiper Belt is too far away from the Earth, and with the current space technology of human beings, it will take several years or even more than ten years to come back and forth from Kuiper Belt, and if you want to use the small stars in the Kuiper Belt to transform Mars or Venus in such a long time, then the time required is too long.

After all, there are not many asteroids needed to transform Venus or Mars, and there are also requirements for volume, so Gong Daming's empire only chooses the asteroid belt between Mars and Jupiter, and of course, it can also use the moons of other planets in the solar system to transform Mars or Venus.

But for the moons of other planets in the solar system, with the current technology of human beings, they are not yet able to move them out of their original orbits and fly towards Mars or Venus.

Therefore, the relatively large asteroids in the asteroid belt have become the best choice for the Ming Empire at present, especially the three largest asteroids in the asteroid belt.

Therefore, Geng Mingzhong and their explorer 2, the main exploration target in the asteroid belt this time is also these three asteroids, especially for the material composition and orbit of these three asteroids to make a preliminary and detailed investigation, after all, changing to Mars or Venus is not only enough to explore Mars and Venus itself, but also to conduct a detailed investigation of the asteroids that hit them.

After all, there are such a large number of asteroids in the asteroid belt, and without the help of these satellites, it is still difficult to find these three asteroids in the vast asteroid belt.

Although they are not very far away from the exploration satellites, they are actually not close, after all, these exploration satellites were launched before Explorer 2 entered the asteroid belt, and now the speed of Explorer 2 is already very slow, after all, flying in the asteroid belt is not as good as other places, and they have to do all kinds of data exploration in the asteroid belt, so their speed at this time is turtle speed.

So to get to the place where the exploration satellite is, it takes about two days for Explorer 2 to accelerate and decelerate.

"It's Ceres." In fact, he needless to say, all the people on Explorer 2 know that the planet in front of him is the legendary Ceres.

After all, as the largest dwarf planet in the asteroid belt and the only dwarf planet, it is natural for everyone on Explorer 2 to be curious about him.

For the understanding of Ceres, the largest dwarf planet in the entire asteroid belt, the humans in this world obviously do not know as much as Zhu Lei and the humans in his previous life, even if the aerospace technology of the Ming Empire is much more developed than in his previous life, but after all, compared to Zhu Lei, in his previous life, the Ming Empire is not comparable to the field of astronomy.

After all, the development of the Ming Empire in this area is still too short, and in his previous life, in the middle of the last century, human beings began to conduct aerospace and also made leaps and bounds in the field of astronomy.

For example, the Ceres in the asteroid belt in Zhu Lei's previous life was discovered and announced by humans as early as 1801, but it was not discovered until about 2003 in this world, and at this time, human space technology, especially the space technology of the Ming Empire, was quite developed, and it was no longer a problem to travel to and from the moon.

And for the asteroid belt of Ceres or Zhu Lei proposed, and named, if Zhu Lei does not say it, the astronomers in the Ming Empire of this world will not notice that there is such a dwarf planet in the asteroid belt of the solar system, when this planet was discovered, the entire Ming Empire felt very incredible, if there was no intervention from Zhu Lei, then the Ming Empire wanted to discover this planet at least 10 to 20 years.

And the controversy over Ceres in this world is not as big as Zhu Lei's previous life, after all, the world's science and technology, especially aerospace technology, has been so developed, when Zhu Lei discovered this dwarf planet and named it, the Ming Empire immediately sent special exploration equipment to this love planet for exploration, and after the exploration, the Ming Empire was very sure that the nature of the planet was determined to be a dwarf planet.

This was not the case in Zhu Lei's previous life, Ceres, which was considered the largest asteroid at first, but later due to the deeper human research on it, more understanding of him, so astronomers later upgraded it to a dwarf planet.

Explorer 2 soon arrived near Ceres, and then Explorer 2 began to fly around Ceres, and then Explorer 2 flew out of a lot of probes, and began to investigate fifty percent of the new overall data, and then after these probes surveyed, they landed on the surface of Ceres, and began to collect samples of the dwarf planet and analyze various magnetic fields and material compositions.

And the No. 2 he said took Ceres as the first target of their expedition this time, because when the Ming Empire sent unmanned probes to explore Ceres several times before, according to the data analysis, there should be a large amount of water resources in the ancient city, and whether it is to transform Mars or Venus, a lot of water resources are needed, so the water content on Ceres has a very important impact on human transformation of Mars or Venus.

As the probes on Ceres began to send back data one after another, the staff on Explorer 2 also began to get busy, after all, collecting data on an asteroid is also a very large workload, although such data is nothing compared to Mars and Venus, but it will not be easy, after all, Mars and Venus are so close to the Earth.

Human beings have begun to collect data on Venus and Mars more than ten years ago, and although Ceres said that the Ming Empire had also sent probes to collect data, none of these probes landed on the surface of Ceres, let alone collect data on the surface of Ceres.
