The international cargo spacecraft returned to Mars again, and the asteroid had already hit the earth.

Their banner is to detect changes in Mars.

After many countries capable of detecting Mars sent probes one after another, Universal Corporation came late and finally came over.

Most countries are quietly observing their actions. Although the probes sent in the past, once they enter the Martian atmosphere, they lose contact with the earth because the dust reduces the intensity of signal transmission.

But Universal has given people too much surprise, and people dare not laugh at them, because they are shooting themselves in the middle of the game.

Only when such a spacecraft similar to a large base comes directly to the Martian orbit can it be possible to receive a weak signal penetrating the thick Martian dust.

Many media have expressed limited appreciation for Universal's emphasis on its persistence.

On the other hand, when other countries are unclear and have poor considerations, they rashly send out Mars rovers, which is more like a show than a cautious scientific investigation activity.

Of course, they also made a guess whether Xiao Qiang was planning to build a second base on Mars.

They obviously guessed it right.

This time, Universal is no longer carrying rocket engines that drive asteroids, but various materials to build this planet. Freight spacecraft like this will travel to Mars every two years from now on. For this planet to grow into a home suitable for human habitation as soon as possible, and transport materials.

On the interstellar spacecraft, a detection aircraft quietly left the mother ship and flew towards Mars below.

The clouds on Mars are very thick, much thicker than expected.

This is because the result of dozens of shocks not only swept countless Martian dust across dozens of kilometers of the sky, but also regasified the frozen gas in the soil and gushed upwards.

The scorching high temperature brought by the impact also melts the ice on Mars into gas, increasing the thickness of the Martian atmosphere.

Another important factor that causes changes in the thickness of the atmosphere is the rupture of the mixed Mars shell, which erupts from the core of the movement inside Mars.

The composition of these gases is very complex and contains many substances produced by high temperatures inside Mars.

They whizz past the surface of Mars, rolling the melted sea water up to hundreds of meters high!

The violent flow of the atmosphere also makes the clouds above Mars like a tumultuous sea, surging.

The impact of asteroids with a diameter of one kilometer on Mars is much more serious than scientists have imagined. They are everywhere volcanic eruptions caused by the crust rupture after being hit by planets.

The gushing magma is like flowing water, pouring downwards. Then it slowly solidifies, forming one strange terrain after another.

At the same time, the impact result also caused the orogenic movement of Mars again.

If there was only one asteroid impact, it would not have resulted in such a result. But dozens of asteroids, in a very short time, the impact of one after another would lead to a terrifying disaster. The crust oscillation caused by the first impact has not stopped yet, and the next violent impact has followed one after another. The crusts in some fragile areas cannot withstand one after another and squeeze and shatter one after another.

The subsequent volcanoes gushed up the instability of the earth's crust, and the short-term orogenic movement was once again artificially induced.

This is not a mountain range that gradually formed after hundreds of millions of years of activity in the earth's crust. It is the result of violent operation and must have the shadow of violence.

The fragile crust breaks, crushes each other, squeezes each other, pushes one mountain to the ground, and then makes one original mountain after another collapse and turn it into deep valleys and trenches.

It comes and goes quickly.

As the original energy was exhausted, it quickly returned to calm.

The violent crust movement lasted for two years and finally subsided and became less terrible.

Because the diameter of the asteroid chosen by Universal Corporation is limited after all, it did not cause the surface of Mars to collapse completely, and orogenic movement did not form the kinetic energy for repeated operation.

It was the detection of the atmosphere rolling on the surface of Mars that it obviously began to calm down, indicating that Mars' violent internal operations had subsided, and Xiao Qiang sent the first interstellar spacecraft to explore.

As soon as the aircraft entered the Martian atmosphere, it began to tremble sharply.

This is not the moon without air. Due to the rebuilding of the atmosphere in the short term, billions of tons of gas and dust rushed into the sky. Although as time goes by, part of these gases will diffuse in space and part of them will settle down. But for now, the density of Mars' atmosphere is no less than that of the Earth.

Moreover, since there is almost no oxygen, it is impossible for the aircraft to use ramming, turbine and other engines to provide power like on Earth. Every second it flies, it consumes the liquid oxygen it carries.

When the fuel is exhausted, it has no motivation to rush out of the atmosphere again and can only fall to the surface of Mars.

The atmosphere of Mars is already very "generative" compared to two years ago. In the two years when it was hit, the atmosphere of Mars can only be described in one word, that is: violent!

Although the detector is shaking very hard now, it can finally fly in the atmosphere without disintegrating directly.

"Sulphides, dust, carbon dioxide, hydrogen compounds..., good guy, whoever goes down will die!" An atmosphericist kept shaking his head while reading the data sent back from the detector carried by the aircraft.

"The situation is generally moving in a positive direction. Look at this chart, which is the data test result when we arrived here last month. Judging from the comparison of various data, some heavier dust has begun to land. At the atmospheric crown position, their content has been reduced to a tolerable level." Another scientist said optimistically.

"Is there a lot of gases escaping?" another scientist came over and asked.

"It's quite ideal. This time, Mars was only hit by dozens of asteroids one or two kilometers, and the impact was not big. This is not like when the planet first formed.

They are all madly and rushing most of the gas out of the gravitational circle. They have already quieted down. It is estimated that the amount of gas escapes is less than one ten thousand." The first scientist reader data said happily.

"In another half a year, the atmosphere will be almost stable."

Several scientists fell into deep thought, half a year later, it was time for them to plan their next plan.

A scientist stretched: "Okay, our work today is done. Whoever wants to go to the rotation gravity cabin, I'll invite you to have a drink."

An old researcher in his sixties gnawed: "You'd better go. I'm old and can't stand the impact of the rotating gravity compartment. Every time I go in, I feel a tingling eardrum. I'll go and look at other data, make statistics and comparison charts, etc."

Several young scientists shrugged their shoulders and floated towards the gravity cabin.

It is different from the movement of broken plates on the earth, constantly squeezing each other, forming frequent earthquakes.

The crust of Mars is a complete piece, and the data transmitted through the probe was sent back. This time, the crust of the earth was destroyed and did not completely break the Mars crust.

Although there are many damages and frequent volcanoes, the Martian crust is still a complete continent.

This makes Mars geological activities lose their main source of power. Therefore, when volcanoes erupt one after another and release the kinetic energy accumulated inside, Mars quickly calmed down again.

From the third month, scientists were surprised to find that it started to rain on Mars!

Due to violent atmospheric movement, it began to flatten, and the heat generated by atmospheric friction was also decayed. Moreover, because dust blocked the direct sunlight, the temperature of the Martian air circle quickly dropped to a certain extent at an unexpected speed.

The temperature of the high air flow ground drops particularly quickly.

The water vapor that was swept to the high altitude formed small water droplets under the action of cold air. Under the action of gravity, the small water droplets drizzled down, carrying the dust in the atmosphere and a large amount of harmful and toxic substances, and returned to the embrace of Mars.

If you orbit normally, some asteroids bring organic matter from space will settle down on Mars along with the dust.

Perhaps, some organic matter will develop in the direction of higher life as time goes by.

But what is more likely is that when the planet's movements completely end, when the surface of Mars is surrounded by the severe cold again, it will be frozen again and will lose the possibility of further evolution forever.

What the world people have to do is to prevent this from happening!

In the fifth month, the exploration aircraft brought back good news: the temperature on the ground of Mars has dropped to twelve degrees Celsius, and the temperature of the sea water has dropped to 25 degrees Celsius!

At this temperature, some warm water-based algae can already survive and reproduce in seawater.

The spacecraft did not release the detection aircraft, but instead bounced out of the spacecraft and landed onto the ocean area.

When the barrel enters the atmospheric circle and the temperature rises to a certain level due to atmospheric friction, the device set in the barrel will explode and put the billions of warm water-based algae carried inside into the sea.

Algae are the most primitive photosynthesis creatures and are also the hero of all living things on earth today.

Without algae, there would be no Earth today. The early Earth was like Mars today, without oxygen, only carbon dioxide and various toxic gases.

It is the algae that absorbs carbon dioxide and various harmful substances in the atmosphere and releases oxygen. Some of the oxygen is converted into ozone in the atmosphere and forms the initial ozone layer, which allows various organisms to reproduce and evolve.

What Universal is doing now is just to re-trace the development history of the earth.

However, the algae they put out are all species that have been modified by biological genes. Their ability to withstand high temperatures and absorb carbon dioxide and harmful substances has been increased by 30%. The most important point is that its reproduction speed has reached twice that of the original mother!

Perhaps, in the Martian sea in the future, algae will become a disaster.

But now, people need them, and they need them to turn the planet that humans cannot survive into the future paradise of human beings.

In addition to algae, scientists are also putting grass seeds and lichens into the land in large quantities.

Lichen is actually also a kind of algae, or a symbiont of algae and fungi. Most of the cells of lichen are fungal cells, and a small number are algae cells. The two organisms are closely combined on the same organism.

It is manifested that lichen-Piaotian-Long-Long; it is possible that when he was still alive, scientists successfully conducted research on human genes and developed a good recipe for prolonging life. Then, by then, he might have other ideas.

But now, he is just a Martian.

The expansion of the base and the large-scale planting of plants have also increased rapidly.

In terms of the oxygen content produced by the green plants in the base, it has long exceeded people's survival needs. It is even accommodating tens of thousands of people and supplying their survival needs, and there is no problem.

Some of the excess oxygen penetrates into the outside world through the gaps that are not tightly sealed.

Now, there are not many animals and healing bacteria on Mars. Oxygen is supplied to the atmosphere unilaterally without asking for returns. According to the simulation operations of scientific researchers through supercomputers and the current expansion rate, as long as the personnel control the increase in the scale of 10,000 people per year, Mars will become a human in 40 years in 40 years.

The planet!

The arrival of new personnel has predicted that new expansion will accelerate.

The electromagnetic gun was built, and the spacecraft was still in the Martian atmosphere, releasing more than a dozen large reconnaissance satellites.

Through the receiving station on the Mars ground, Mars has built a preliminary defense system.

The moon's weak gravity environment created conditions for the spacecraft to take off directly from the moon and transport a large number of materials. It was also a entrepreneurship and after obtaining the lunar base, the entrepreneurial process of Mars was obviously much easier.

By the fifth time, Lin Yi and her whole family came, and the moon base also began a major migration.

The surface of Mars is covered with translucent tents scattered.

According to the future development plan, the surface of Mars is divided into several parts, and from the beginning, it has been implemented according to the unified planning and the progress of synchronous development.

Transparent tent gathering areas make the prototype of these future cities.
