After exploring Europa, the Hornets collected detailed data on Europa, Europa, and the other three largest moons of Jupiter, and also landed on these planets to collect samples of the planets.

And after each completion, they send detailed data back to the moon.

After exploring Jupiter's four moons, they really set out on their journey to the edge of the solar system.

At this time, the Moon's Mars Transformation Program Symposium has been going on for nearly a year, and in such a long time, the Mars Transformation Symposium has come up with a preliminary transformation plan and began to make further preparations.

And Zhu Lei Yongan Group has sold nearly 2,000 small mining spaceships to the entire Daming, and even sold dozens of medium-sized space mining ships, while the real large space mining ship has not been sold by Yongan Group so far.

However, for the large space mining ship Zhu Lei, his Yongan Group does not want to sell it to the private sector for the time being, after all, it is enough to mine asteroids and Kuiper belt minerals in the solar system, small mining ships and medium-sized mining ships, and there is no need to use large space mining ships, of course, large space mining ships are for the Ming Empire.

And during this time, Zhu Lei also added more than 300 space warships for his Suzaku Army, the largest of which reached a length of more than 1,500 meters, and the tonnage exceeded one million tons, which is also the largest spaceship in the Ming Empire.

And the technology used on this spacecraft is also the most advanced technology in the Ming Empire at present, as far as the electromagnetic railgun is concerned, the power is many times more powerful than the previous one, and the speed of the projectiles fired by the most powerful main cannon can reach 0.7 times the speed of light.

However, this speed is also the highest speed that human technology can achieve at present, if you want the cannonball to fly faster, then it is impossible with the current technology of the Ming Empire, of course, with the development of science and technology, the speed of the electromagnetic railgun of the Ming Empire will definitely increase, but because the faster the speed, the greater the mass.

If you want to continue to increase the speed of the electromagnetic railgun projectile, the amount of energy required is also very large.

After this period of intense construction, Zhu Lei's Yongan Group is building, the first phase of the space smelting base project has finally been received, and the steel output of the entire Ming Empire and the output of other metals have also increased nearly twice, but although the metal output has increased significantly, but for the current Ming Empire.

Such steel production is far from satisfying, because with the pace of the Ming Empire towards the sea of stars faster, more and more metal materials are needed, although during this time, the Ming Empire's officials also began to build various smelting plants on a large scale.

But in fact, the demand for steel in the Ming Empire is also growing rapidly, but this situation will be effectively solved after the completion of Zhu Lei's second phase of the project, because the second phase of the Yongan Group's project is definitely much larger than the first phase of the project, and the technology is more advanced, and the output is more than ten times that of the first phase of the project.

At that time, the steel output of the Ming Empire will basically be flat, but because the demand for metals in the Ming Empire is also growing wildly, the second phase of the project will enter the third phase of the project immediately after the completion of the project, and only in this way can it keep up with the demand for various metals in the empire.

Finally, after more than a year of discussion at the Mars plan symposium, an effective implementation plan was finally reached, and this plan was basically agreed by most of the people present, although it is quite dangerous to transform Mars, after all, a slight mistake will be a huge disaster for mankind, and may even lead to the extinction of the country.

However, everyone knows that if the Mars program is not carried out, the development of human beings will be very restricted, and the entire human civilization will definitely collapse in the near future due to resource reasons, so whether it is the high-level of the Ming Empire or all the scientists present, it is very clear that the Mars program will definitely be carried out.

Zhu Lei stood in the middle of the conference hall, and then slowly looked around, and at this time, all the scientists in the hall also turned their eyes to him standing in the middle, waiting for him to summarize the Mars transformation symposium.

Zhu Lei took a deep breath and then said, "Hello everyone! I think everyone knows me, so I won't introduce myself too much, and everyone here is the top scientists and scholars in various fields of our Ming Empire, although many people have different opinions about this Mars transformation plan.

And I know that in fact, among the scientific workers who are doing, there are still some people who oppose the Mars program now, thinking that human beings do not need to be in such a hurry to carry out the Mars plan, after all, human beings are not fully sure of the transformation of Mars, and they should wait until the development of human science and technology to a certain extent, and they should start to transform Mars after they have full confidence in the transformation of the planet, so that the safety of the entire human race will be improved a lot.

But time waits for no one, everyone knows that in the past 20 years, the Ming Empire has increased by 300% from the original 5 billion population, which means that all the populations of the Ming Empire have added up to more than 15 billion people, and this data is still rising rapidly in that year.

According to the latest inference of scientists, the entire earth can withstand a maximum of about 30 billion people, which is already the limit, even if you add the moon and various space projects near the earth, the population that the entire earth-moon system can support is only more than 40 billion, and more than 40 billion people do not need 20 years from now on, that is to say, at most 20 years, or even as long as ten years, the entire earth-moon system can be filled.

There may be many people who will say that as long as we slow down the population growth rate, or limit the population growth, so that we have enough time to transform Mars, but I don't agree with their statement, you must know that human beings have now begun to enter the big family of the universe, and the population is one of the largest resources of each universe race, and it is also one of the most important resources, if the race wants to survive in the universe, a sufficient number of people is necessary, and more than 20 billion people, For the whole universe, it is just a very small, very small point, and you can't even see it, and there will be various accidents at any time that will lead to the extinction of the entire race.

So everyone, our time is very precious, our population is still very small, you must know that since we humans have mastered the controllable nuclear fusion technology, we have become an intermediate primary civilization in the universe, that is, the third stage civilization in the universe, and it is also the third stage of the primary civilization, and what is the specific population of the general third stage civilization in the universe, generally speaking, the population of the third stage is about 100 billion on average, and the entire human civilization is now less than 21 million people, Think about how far we are from the average population of the third stage of civilization.

So in order to feed more people, we have to start doing it right away, if I have the possibility I want to start tomorrow, we don't know when the alien civilization will come to the solar system, and what will be the purpose of their coming, war or peace?"
