In the following days, Zhu Lei and the others have been cleaning up the debris produced by the impact, and distinguishing the types of these debris, leaving the useful and useless ones directly to Mars, after all, there are a lot of debris that flew out of the Martian impact, and even now the mineral resources collected are enough to make nearly 100 space warships.

And in the past few days after the impact, in addition to sending thousands of unmanned probes to Mars, although the metallurgical technology and material technology of the Ming Empire have been very advanced, but due to the very harsh environment on Mars at this time, the death rate of these probes is as high as more than 80%, and the remaining 20% survival rate will not exceed 48 hours, and the probes previously arranged on Mars, as well as various probes and artificial equipment on Ceres, At the moment when the two planets collided, they were directly destroyed, and none of them were spared, and most of the planetary thrusters on Ceres had been withdrawn after entering the Martian gravitational sphere, and the remaining small part, due to the water vapor eruption of Ceres, and the effect of Martian gravity had been damaged, so it was directly used as a land probe on Ceres, but because these planet thrusters were too large, before Ceres and Mars collided, These planetary thrusters have been completely destroyed.

It can be said that during the Mars collision, all the various probes on Mars and various artificial facilities on Pangea were all destroyed, but fortunately, these probes were not worthless, but such a thing was long before the Mars plan really began to be implemented, Zhu Lei and many scientists in the Ming Empire had expected such a thing to happen, so the information of these probes was transmitted in real time, so the collision of Ceres and Mars, Zhu Lei's Cosmic Celestial Laboratory and Planetary Structure Laboratory have obtained quite a large amount of data, which is of great value for human beings to transform other planets in the future.

Just when Zhu Lei and the others continued to block the debris, there was a major good news from the Lunar Cosmic Celestial Research Center, that is, the magnetic field of Mars has begun to recover, although only about five percent of the Earth's magnetic field has been restored, but this is undoubtedly a very important good news.

After all, the magnetic field of a planet is like a huge protective shield, protecting the planet from the invincible attack of various high-energy particles in the universe, especially the attack of the solar wind, because there is no protection of the magnetic field, the atmosphere above the planet is very easy to be swept away by the solar wind, so the magnetic field of the planet is very important for a planet, and now the magnetic field of Mars has begun to recover, and has reached 5% of the earth's magnetic field, which is a great news, but unfortunately according to the calculations of the computer, The magnetic field of Mars can eventually reach about 15% of the Earth, after all, the heat caused by the impact is still far from enough, especially when the core of Mars is basically cooled, it is very difficult to reheat the core of Mars, and there must be an asteroid impact with a hot core to be able to completely recover the magnetic field of Mars.

There is also the fact that after exploration, the gravity of my heart has also increased significantly, because the volume of Mars has increased due to the impact, and its rotation speed has accelerated, and now it has reached 40% of the Earth's gravity, but this gravity is still far from enough for people who want to live on Mars for a long time, so Zhu Lei and they have to find a way to continue to increase the volume of Mars, after all, if humans want to live on Mars for a long time and healthily, the gravity of Mars must reach at least 85% of the Earth, but at 85% The gravitational pull of the left and right.

So Zhu Lei set his sights on the other two largest asteroids in the asteroid belt except Ceres, and in addition to the asteroid belt, Zhu Lei turned his eyes to Jupiter's moons, especially Jupiter's Io, although the volume of Io is huge, if it hits Mars directly, there is no doubt that it will directly hit Mars, but because Io has a hot core, it is very likely to make the magnetic field of Mars fully recover, and because the volume of Io has reached a full 3000 kilometers, It will be half of Mars, so it will also play a very important role in the increase of Mars' volume and mass, as well as gravity.

And in addition to Europa, Zhu Lei also plans to include some other smaller moons of Jupiter, of course, this does not include Jupiter's other three relatively large moons, these three moons are Europa, Europa, and Ganymede, after all, these three relatively large moons have huge water resources, and these water resources are to be used in the future transformation of Venus, so these three planets must not be moved.

But Jupiter's other moons don't matter, you must know that Jupiter in the solar system, it has 68 moons, and the smallest of these moons is a few hundred meters in diameter, and the largest moon is more than 3,000 kilometers, and Io is more than 3,600 kilometers in diameter, making it the fourth largest moon in the solar system.

In addition to the four largest moons of Jupiter, the possibility of containing water resources on other moons of Jupiter is also very large, although the storage of water resources of these aliens is not very large, but it is also very important for Mars, after all, the water resources of fire are still very scarce.

At this time, the biggest change on Mars is the temperature, at this time the average temperature on Mars has reached more than 100 degrees Celsius, so the poles of Mars you created began to melt rapidly, making the atmosphere of Mars also thicker a lot.

However, at this time, the volume of Mars is far from enough, so it is necessary to continue to increase the volume of Mars, and the project is such a huge moon, if you want to merge with Mars, it is not time at all, because Mars is still in an extremely unstable state, and the volume of Mars is not large enough, so according to scientists, it will take at least a year before you can use a relatively large asteroid to impact Mars, and if you want to use Europa to impact Mars, it will take at least 5 to 10 years. Wait until the volume of Mars increases to a certain extent before it can be implemented.

And now the number of spaceships in the Ming Empire is far from reaching the level of prying Europa, and the volume of the spaceship is still too small, after all, the weight of the largest spaceship of mankind is only fifteen or six hundred tons, and if you want to pry Europa, the number of spaceships will at least increase by dozens or even hundreds of times before it is possible to pry Europa.

Therefore, the Ming Empire will take at least five years to prepare, so during this time, the Ming Empire must find a way to increase the volume of Mars as soon as possible, so that he can withstand the impact of Europa fragments.
