MTL - The Return of the Black Technology of Immortal World-v3 Chapter 305 rain on mars

Time passed quickly, and it was another two years in a blink of an eye.

Two years may not seem like a long time, but for Mars, earth-shaking changes have taken place.

From the time when the first asteroid fell on Mars, one or two asteroids fell on Mars every month thereafter.

In two years, a total of thirty-one asteroids have merged with Mars.

Mars seems to have returned to ancient times, when the solar system was just born.

At that time, not only meteorites of varying sizes fell at any time, the planet that had not yet begun to cool down, but also volcanic eruptions, and everywhere was shrouded in hot lava.

Now Mars has spread all over the world, more than one hundred active volcanoes are erupting, and a large amount of volcanic ash and volcanic gas cover the entire planet.

Therefore, Mars, which is already very close to the atmospheric pressure of the blue star, is completely covered by volcanic ash, just like Venus, and there is no way to see the surface.

Now Mars can no longer see the dense iron oxide grit on the surface, so it can no longer be called Mars at all.

Just like the situation on Venus, even if the thick volcanic ash blocked the sunlight, the entire Mars should have entered an ice age.

However, a large number of volcanic eruptions and the existence of a large amount of greenhouse gases caused the surface of Mars to jump from the initial below zero to an average of more than 50 degrees.

Mars is still too small, and the cooling rate was too fast at the beginning, so it can't turn into a hot **** like Venus, but it is still not suitable for human survival.

Because the volcanic gas contains various components, and because of the hot surface, all kinds of things that should have become liquid have also become gaseous, so the color of the atmosphere of Mars is not colorless, but colorful mixed with volcanic ash. .

But even if Mars has become like this, the act of throwing asteroids at it has not changed at all. At most, there are fewer rocky asteroids and more water-rich asteroids.

With modern detection methods, the surface of Mars can naturally be seen through the thick volcanic ash.

Because of the eruption of the volcano, the entire Mars was covered by thick clouds. The friction of the clouds caused two opposite charges to collide, and then lightning began to occur. Even through the clouds, the light of lightning could occasionally be seen.

With clouds and lightning, another thing, rain, appears naturally.

Falling on Mars, the melted icy asteroids have formed several lakes, or relatively small seas.

With rain, the water vapor evaporated from the sea, in addition to filling the gullies on the land, part of it also flows back to the sea.

So a preliminary water cycle system began to be established.

Although this system is still very fragile, it often occurs that the entire sea is swallowed due to a geological change.

But as the icy planets were thrown in, the water content on Mars continued to increase.

And Xiao Ai's actions never stopped.

Because the speed of the spacecraft reaches one percent of the speed of light, travel within the solar system is already easy. Even the Kuiper belt, which is 30 astronomical units away, can be reached in just over 17 days.

Even counting the time for acceleration and deceleration, it is only a mere month.

Thinking back to the last century when airplanes were not yet in use, crossing the ocean, even if it was a ship using a steam engine, the time would still last for more than a month.

And even the widest Pacific Ocean is only 10,000 kilometers wide, which is not comparable to the Kuiper Belt's distance of 4.5 billion kilometers.

But this represents that the determination of human beings to pursue speed has not changed. Jumbo jets have shortened intercontinental travel to less than one day.

Now taking the spacecraft at the Moon Palace base, it will take less than ten hours to reach the moon.

Because of the increase in the speed of the spacecraft, Xiao Ai already has the ability to explore the entire solar system.

Just before No. 1 and No. 2 dragged the asteroid back, many exploration spacecraft have carried out detailed detection of many asteroids that have become targets.

Although asteroids that are all metal substances have extremely high value, they cannot be used as weight-increasing materials for Mars.

Because they are too heavy, nearly twice the mass of ordinary asteroids, the impact on Mars caused extremely serious damage.

Although their relative speeds are almost the same when they meet, as the asteroids approach, the gravitational force between each other will accelerate the asteroids to a relative speed of more than several kilometers per second.

This speed coupled with the mass of the asteroid itself tens of billions of tons, the impact force can be imagined.

If it's just one or two, it doesn't really matter, but their goal of increasing the weight of Mars has reached more than 20% of the total mass of Mars.

Too much mass that does not belong to Mars, if placed on Mars on average, it doesn't matter, it will only make Mars bigger and heavier.

But when a heavy asteroid is also extremely strong, it will directly break through the protection of the earth's crust when it hits.

At that time, the damage caused directly reached the mantle of Mars, and even the core. For a planet, the damage was extremely deep.

If there are more such impacts, then Mars is not far away from being torn apart.

Therefore, the asteroid Yang Qing chose was either mainly composed of rocks or contained a lot of water. Such an asteroid hitting Mars is like an egg hitting a rock.

Although the kinetic energy is almost the same, its damage is basically maintained at the level of the shallow layer of the earth's crust or mantle.

This is considered to add mass to Mars, and the heat converted from kinetic energy will further heat Mars.

And the angle of the impact must be strictly calculated, and it must be kept symmetrical, so that there will be no change in the orbit of Mars due to the impact~www.novelbuddy.com~.

This is also the reason why only one or two asteroids hit each month. Otherwise, with Xiao Ai's work efficiency, a thousand asteroids could be smashed down within a year.

After all, the orbit of Mars was cleaned up after billions of years. A slight deviation, even if it is a few tenths of a degree, may lead to the phenomenon that in a year, a certain season is full of enthusiasm, and other seasons are frozen into dogs. .

It is also possible that because of this deviation, an asteroid or comet that often visits the inner solar system happened to meet Mars.

At other times, Yang Qing would actually be eager for a collision, but the impact of this orbital change in a short period of time is actually invisible.

Accidents can be decades, or even centuries, away.

However, Yang Qing's estimated Mars transformation time will not exceed 50 years. In about ten years, Mars needs to form a basically stable geological structure.

Twenty years later, the modified Martian atmosphere can basically meet the needs of ordinary people.

Although it seems a bit fanciful to condense the changes of the past hundreds or thousands of years into a period of more than ten years.

But with the addition of aura, all this became possible.

In the prehistoric times, we would often encounter this kind of world fragments, and many conditions were not even as good as Mars.

However, through the blessing of various formations and the birth of spiritual energy, all this became possible.
