It has been nearly two years since Europa and Mars became one, and in the past two years, the Ming Empire, whether it is the Vermilion Bird Army, or civilian mining ships, especially medium and large mining ships, have brought back countless cold asteroids from Kuiper, and most of these asteroids contain water resources.

So in the past two years, Mars has been subjected to countless meteorites every day, these ice meteorites brought from Kuiper have large and small masses, the largest diameter is more than hundreds of kilometers, and the smallest diameter is hundreds of meters, when these meteorites collide with Mars, they often produce huge energy, because most of these meteorites are ice meteorites, so after the impact, these ice meteorites will be evaporated into water vapor and rise into the atmosphere of Mars.

Then a huge cloud layer was formed, and then a storm was formed and landed on the surface of Mars, but because the surface temperature of Mars was still quite high at this time, the water that landed on the surface of the earth would be evaporated again and again into the air to form patches of clouds, so the temperature of Mars began to gradually decrease.

It can be said that the entire Mars from the beginning of the merger with Europa to a month ago, there were lightning and thunder, black clouds, heavy rain poured, did not show more than half of the true appearance, at a glance the whole Mars seems to be covered by all kinds of large and small clouds, and the clouds from time to time also emit strong lights.

However, the drastic changes on Mars have slowly calmed down since a month ago, although the current environment of Mars is still very bad, but now from space it looks like Mars can already see its full picture, and the clouds on Mars have become much thinner, and extreme weather such as lightning and rain is also much less.

At this time, Mars is covered with all kinds of rivers, lakes, mountains, etc., everything is very different from the original Mars, especially the color of Mars, the original Mars is red but has now turned dark brown, this is due to the impact of the iron oxide on the surface of Mars and the erosion of rain, so the color of the Martian soil itself will be exposed, but in some places you can still see piles of iron oxide gathered in one placeIf it takes long enough, then these iron oxides will slowly form iron ore and distribute it on Mars.

And the rudiments of the ocean have begun to form in the lower part of Mars, so you can still see the blue sea on Mars from space, and the blue ocean still occupies 3/5 of the territory of Mars, although Mars is not as beautiful as the Earth at this time, but Mars is undoubtedly beautiful compared to other planets in the solar system.

So if you stand on the earth and look at Mars with a telescope, people will find that Mars at this time is very different from the original, the original Mars has only one color, that is, red, but now just look at Mars, its color is no longer monotonous red, its color has become a color composed of blue and brown, blue is the sea of Mars, and brown is the land of Mars, and occasionally a little red can be seen in the middle of the brown, that is where the original iron oxide of Mars is piled up.

And you can still see patches of white on the whole Mars, that is, the water vapor floating in the Martian atmosphere, the thick clouds of the Martian Mountain, it can be said that Mars at this time is very beautiful and very charming, but unfortunately Mars is not green yet.

After all, although the environment of Mars is much better than before, the environment of Mars has not yet reached the standard that can be transformed, in fact, the crust of Mars is still quite weak, only less than ten kilometers deep, and the surface temperature of Mars is actually quite high, and the temperature in some places even exceeds one hundred and fifty or sixty degrees, and organisms cannot survive in such an environment.

After all, it has only been less than two years since Mars and Europa became one, and the energy generated by the impact must not have been completely dissipated in such a short period of time, not to mention that because the core of Mars and Io have become one, the core of Mars has begun to become hot again, and although it seems that the surface of Mars has calmed down a little now, in fact, the changes in the interior of Mars have just begun.

But if you want to change the environment of Mars, you must use biology to change, you must know that the oxygen content of Mars is still very small, and the most important content in the atmosphere is carbon dioxide, at this time, the carbon dioxide content in the atmosphere of Mars has reached more than 80%, and such a high carbon dioxide content is simply not possible for humans to survive in it, and now Mars has undergone more than two years of changes, and now Mars has a thickness of nearly 90 kilometers of atmosphere, which is almost the same as the Earth's atmosphere. However, the concentration of the Martian atmosphere is far from being comparable with that of the Earth, so in the next time, human beings will increase the concentration of the Martian atmosphere on a large scale, so that the atmospheric pressure of Mars will reach the standard of the Earth.

However, it is still a question where the gas to increase the concentration of the Martian atmosphere comes from, after all, there are no asteroids that can provide gas in the entire solar system, so Zhu Lei and the scientists of the Ming Empire preliminarily discussed, in addition to taking local materials on Mars and using various means to increase the concentration of the Martian atmosphere, they are also preparing to collect various gases on Venus and release them to Mars.

After all, after the initial results of the transformation of Mars, the Ming Empire will immediately start the Venus project, and the atmospheric concentration of Venus is too high compared to the earth, so the atmosphere on Venus will definitely be diluted at that time. Venus may disappear into the solar system, so these methods were basically vetoed by the Ming Empire and Zhu Lei.

For example, a scientist proposed to use a relatively massive asteroid, or a planet to skip Venus up close.

Then use the gravitational force and inertia of the planet to fly the gas on Venus, or use a relatively massive asteroid, such as an asteroid the size of Io to hit Venus, and use the impact force to throw these gases out of Venus, but these plans are very unrealistic, and have a fairly high risk of starvation, and even the Earth will be affected.

For example, using a relatively large asteroid with a relatively large mass to skip Venus and bring other things on Venus into space, not to mention whether this method is feasible, whether it can bring the gas of Venus out of Venus, and using this method is to first find a planet of comparable volume to skip Venus, but the largest moon of the solar system is Ganymede, and the volume of Ganymede is very large, reaching a diameter of more than 5000 kilometers, which is only more than 1,000 kilometers less than Mars.

It is really appropriate to use it to skip Venus, but how to move such a large moon, you must know that two years ago, the Ming Empire spent countless manpower and material resources in order to move Europa, if you want to move Ganymede, on this basis, the manpower and material resources are at least more than ten times, and it may not be able to move.

The second is whether it can ensure that Ganymede accurately skips Venus and takes away the atmosphere above Venus, which is a very uncertain factor, after all, the volume of Ganymede is too large, and there is no way for it to accurately skip Venus with the current technology of mankind, instead of colliding with Venus, not to mention that this will also have a great impact on the earth.

After all, when a planet passes over Venus, the gas will definitely float in the space near Venus, and eventually most of these gases will be pulled back by the gravitational pull of Venus, while a small part will be attracted by the planets near Venus, and the Earth, which is also the closest to Venus's orbit, will become a hard-hit area, so this plan is absolutely not feasible.

In addition, hitting Venus with a relatively large asteroid will have the same effect, so neither method is feasible.

In the end, the plan proposed by scientists is to establish a carbon dioxide collection factory floating in the stratosphere on Venus, specifically collect carbon dioxide gas on Venus, and then make dry ice and put it on Mars with a spacecraft, so that it can kill two birds with one stone, since it can reduce the carbon dioxide gas on Venus, and reduce the atmospheric concentration on the surface of Venus, and can increase the atmospheric concentration of Mars, the atmospheric pressure of Mars meets the standard of human survival.

So as soon as this plan was proposed, it was recognized by most scientists, although it took a bit of time for this plan to take a long time, it may take more than ten or twenty years or even longer, but it is still early for humans to transform Venus, so now the Ming Empire has time to reduce the concentration of Venus's atmosphere.

It can be said that although the environment of Mars has initially begun to calm down, but in general, Mars is still a forbidden area for human beings, and if you want to immigrate to Mars, you will have to wait at least 10 to 15 years later, but Mars transformation will be able to put a variety of improved plants in a few years, and the biotechnology of the Ming Empire has made full progress in the past ten years, and human beings have a very thorough understanding of various creatures in nature, so human beings have a very mature understanding of plant improvement technology.

And in order to test what plants are more suitable for the Martian environment, Zhu Lei Yongan Group also went through a lot of unemployment and finally identified several plants, most of which are algae, but there are also some other plants.

As for the animals, Zhu Lei does not plan to put them on Mars at present, at least until the initial transformation of the environment of Mars is successful, suitable for the survival of animals before they can be released, although after genetic improvement, these animals can adapt to the environment of Mars, but at present, it is not known whether these genetically improved animals will mutate after arriving on Mars, and whether it will have a fatal impact on humans after human immigration to Mars, so it is necessary to understand thoroughly before it can be put on Mars.

Although there is still a long time of 10 to 15 years before the timetable for human immigration to Mars, this does not prevent the people of the Ming Empire from caring about this matter, and now the Internet and major media of the Ming Empire are full of changes on Mars every day.

The carbon dioxide collection plant on Venus has been started a few years ago, and most of the carbon dioxide collection factories on Venus have been started until now, and these factories are all unmanned automated factories, after all, the environment on Venus is simply not adapted to humans, even if they stay in the stratosphere of Venus, the temperature has reached hundreds of degrees, and no one wants to stay in such an environment to live, even if they live in a carbon dioxide collection plant.

It can be said that the route between Venus and Mars is very busy now, there are countless spaceships shuttling through it every day, in the carbon dioxide collection factory of Venus, loaded with dry ice formed by carbon dioxide, and then fly to the vicinity of Mars, directly put these dry ice on Mars, and the official price of each trip to the Ming Empire is also very high.

After all, due to the increase in space mining ships, all the asteroids with slightly larger volumes in the entire asteroid belt have been towed away by these mining ships, and the remaining ones cannot be called asteroids at all, and most of the remaining volumes will not exceed ten centimeters, so from now on, the asteroid belt can only be called the outer meteorite belt.

However, there are still a lot of mining ships busy shuttling in the asteroid belt, and the income of these mining ships is completely incomparable with that of a few years ago, so they are no longer picky about asteroids.

Instead, it is a dragnet collection, whether it is large or small, as long as it touches all the bags and takes them away, and then decomposes, leaving all the valuable ores and those useless ones and transporting them to Mars.

However, most of the mining ships of the Ming Empire are no longer engaged in the mining industry, because the entire inner circle of the solar system, asteroids with slightly larger volumes, and meteorites have been collected.

Therefore, most of those small mining ships have been converted into short-range space cargo ships, and the main route is the cargo service between Earth and Mars, Mars and Venus, Venus and Earth, and now the main object is the official of the Ming Empire.

The remaining asteroids are basically more than 500 kilometers in size, and such a huge asteroid and these small mining sites are simply powerless, even medium-sized mining ships cannot be dragged by these asteroids.

However, because the medium-sized mining spacecraft has a long range, heavy armor, and the ability to resist various cosmic rays, these medium and large spacecraft have a better goal, that is, the Kuiper belt, for those thankless asteroids of more than 500 kilometers are not eyed at all, not to mention that most of these asteroids of more than 500 kilometers have been marked by the Ming Empire, and private mining is not allowed. Because these asteroids will all be dropped on Mars in the next two years to increase the volume of Mars.
