It was really an unexpected discovery for them to discover organic matter on an asteroid. Although the content of organic matter in the soil was extremely small, organic matter was actually discovered.

Organic matter is the material basis for the production of life. All living things contain organic compounds, including fats, amino acids, proteins, sugars, etc., all of which are organic compounds.

Metabolism and biogenetic phenomena in living bodies, which all involve the transformation of organic compounds.

The discovery of organic matter on this asteroid can also prove from the side that in the universe, planets that produce life forms must not only exist on the earth.

With organic matter in the universe and a suitable environment, it may not be impossible to produce life, such as the super-Earths previously discovered by earth scientists in the universe.

The environment there and the environment on the earth are almost like a replica of the earth in observation. In an environment that is not much different from the earth, and with the presence of organic matter, the emergence of life has become inevitable.

In such a vast universe, it is not known how many planets have a similar environment to the earth. Even if we calculate it with the smallest probability, we can conclude that human beings are not alone in the entire universe.

It is very possible that life has already appeared on the super Earth that was observed before, and even civilization has appeared on this super Earth. It is very likely that their level of civilization is higher than that of the earth.

The discovery of organic matter made the scientist think a lot, and even gave him a strong sense of urgency to some extent.

This moment allowed them to discover the existence of organic matter on the asteroid. As long as the asteroid crashes onto a suitable planet by chance in the future, the emergence of life will be inevitable under various opportunities.

Such a conclusion will have a huge impact on the entire world. If there is a particularly high-level civilization in the universe, if the other party discovers the existence of the earth, the impact of a livable planet like the earth will be huge. Appearing, it is likely to arouse covetation.

Just like the law of the dark forest written in The Three-Body Problem, if the earth wants to survive in the vast universe, it must be extremely careful about everything on the earth.

After discovering various rare earth resources and organic matter existing on asteroids, the astronauts returned to the space shuttle and immediately held a discussion about how they should proceed next.

During their discussions, the final fate of the asteroid they were on was also decided by them.

In the end, these asteroids will be towed by aerospace planes to fly to the earth. Of course, this move is not done immediately, but after some experiments, they ensure that they can really control the asteroids to land safely. to land.

After finally discussing such a solution, they walked out of the space plane again, and then conducted more detailed information collection on the asteroid.

After they had collected all the information about the asteroid under their feet, and then recorded the coordinates of the asteroid, they left the asteroid in a space plane.

In the vast space of the universe, the number of asteroids is extremely huge. Just like a person cannot count how many hairs he has, the number of asteroids is also countless.

Based on its previous understanding of the universe, the aerospace plane flew towards another known target asteroid.

The asteroid they selected this time is actually not much different in appearance from the one they just left. They are also irregular stars with a diameter of more than one kilometer.

In terms of size, the asteroid they are now targeting is larger than the previous asteroid.

Then they will land on their next target just like they landed on the Nako asteroid before. After a successful landing, they will also collect information on these asteroids to see if there are any targets for the Earth on them. Extremely useful stuff.

If there is nothing too urgent to discover or urgent resources needed by the earth, then they will try to drag this asteroid to Venus, the nearest planet to them, and conduct an experiment on Venus.

That is whether their space plane can completely pull the asteroid. Their ultimate goal is to control the asteroid to land safely on the planet within a controllable range.

If they can control this asteroid and land safely on a planet, then the asteroid they discovered before that contains a large amount of rare earths and organic matter can land safely on the earth under their control. .

When an asteroid is one thousand meters in diameter, its final volume will reach 523.58 million cubic meters. Such a huge volume is likely to be beyond the control of an aerospace aircraft. living.

What's more, the previous asteroid contained a large amount of rare earth. This rare earth is a substance that is denser than earth. It is conceivable that its overall weight will not be ordinary.

It's really not something that an aerospace aircraft can control, so for the sake of safety, it is necessary to continue this kind of experiment.

If we don’t do this experiment, we will really be like a stupid teenager dragging an asteroid with a diameter of one kilometer back to the earth. If the aerospace plane is unable to drag the asteroid by then, the consequences will not be human at all. bearable.

A long time ago, the overlords on the earth were dinosaurs. Although there is no conclusive conclusion as to why the dinosaurs became extinct in the first place, the hypothesis of an asteroid impact is extremely popular.

If an asteroid with a diameter of one kilometer is not towed by a space plane and eventually hits the earth, the earth will be annihilated.

The impact will cause a large amount of dust to enter the atmosphere, thereby blocking sunlight, which may last for up to a year. It will also cause a large amount of sulfuric acid to exist in the stratosphere in the form of aerosols, reducing the amount of sunlight reaching the surface by 10-20%. Ultimately, it prevents plants from performing photosynthesis.

The complete settlement of these aerosols in the stratosphere will take up to ten years, during which time a large number of plants and phytoplankton will disappear, and the impact will be particularly huge.

Moreover, after the impact, a large amount of infrared light will penetrate the atmosphere, causing damage to exposed organisms, and the impact will also cause a global fire storm.

If such a possibility really arises, then humankind will usher in the end. It is very likely that human beings will eventually disappear from the earth like the dinosaurs at the beginning. It is very likely that human beings will become fossils and fossils like dinosaurs in 10,000 years. oil!

Therefore, when considering dragging the asteroid back to Earth as a whole, all possible impacts must be carefully considered. If there is an accident, then human beings will disappear from this world.

At that time, after testing, it would be best if the asteroid can be towed back to the earth in a controlled manner. If it cannot be towed back to the earth in a controlled manner, then they will implement the second plan.

The second plan is definitely not as good as the first one, which is to build a large number of aerospace planes and space mining equipment, complete smelting and purification on asteroids, and transport a large amount of useful finished materials back to the earth through aerospace planes. In this way The cost will undoubtedly be much higher.

Or they use particle weapons to bombard and smash the entire asteroid, and eventually get countless fragments. They transport these fragments of suitable sizes and different shapes back to Earth.

Anyway, there are many plans, but the plan of transporting the entire asteroid back to the earth is the lowest cost plan. If you think about it, you will know that if a complete asteroid is transported back to the earth, won't people be able to mine it however they want?

The asteroid that was now their target was not that far away from their current location. They drove the aerospace plane to the maximum speed, and it took almost more than a week to reach the asteroid that was their target again. .

After going through some series again, using the same process as before on the asteroid, we finally landed on this asteroid.

After landing, intense and orderly inspections were carried out. The various terrains and compositions of the asteroid were all within the scope of their information collection.

Under various strict inspections, the asteroid they were on was thoroughly inspected, and everything on the asteroid was clearly collected by them.

The composition of this asteroid is completely different from the one they detected before. In other words, this asteroid is completely useless to humans.

The top is composed of some very ordinary rocks. They drilled underground in the most concave part of the terrain, and drilled down to a distance of more than 500 meters. According to the factory, an asteroid should have been drilled at such a depth. Core.

But when they got to the core, the material they detected was no different in composition from the material detected on the ground. In other words, the entire asteroid was of the same type.

In the end, such a test result was obtained, which means that this asteroid is of no use at all and has no use value for the earth and humans.

This gave the exploration team a feeling of disbelief. The gap between the asteroid at this moment and the asteroid they had arrived at before was really too big.

The previous asteroid could be said to be full of treasures, but the asteroid they were on now was completely useless. The gap between before and after was too great.

In fact, what they don't know is that the asteroid they are on now is the norm in the universe, but the one they encountered before is not very normal and not very common in the universe.

When they got the second asteroid they arrived, which had no use value at all, everyone looked at each other and made a decision.

The asteroid under their feet will serve as a prop for them in the future, and they will use this asteroid to test the traction technology of the aerospace aircraft.

After the astronauts made their decision, they immediately used the anti-gravity technology of the space shuttle to pull the asteroid up, and they turned the engine to the maximum.

The asteroid's orbit in space began to slowly change under the tug of the aerospace plane. The group of them drove the aerospace plane, pulling the asteroid with a diameter of one kilometer toward them. The nearest planet begins to advance.

The planet they landed on this time was Venus, the closest planet to the Earth and the second planet outward from the sun. Inner planets located inside the Earth.

Venus is also a terrestrial planet that is very similar to the Earth and is often called the Earth's sister planet. It has the thickest atmosphere of the four Earth-like planets. Venus and the Earth are also very similar in terms of gravity. The Earth's gravity is 1g, while the surface gravity of Venus is 0.903g.

It can be said that in terms of gravity performance, Venus is closer to the earth than Mars.

Therefore, in this traction experiment, Venus is undoubtedly the most suitable experimental object.

Of course, the gap between Venus and the Earth is still quite large. First of all, Venus's average temperature is as high as 462 degrees Celsius, making it the hottest planet in the solar system, hotter than Mercury, which is closest to the sun.

Under such an average temperature, it is undoubtedly a luxury to have higher organisms on Venus. It is very likely that there will be some microorganisms on it. Apart from these microorganisms, no higher level of life will exist.

Coming back to the task of towing and landing, as the aerospace aircraft continues to develop and exert force in the universe, the speed of asteroids under the towing of the aerospace aircraft is also constantly increasing.

They are almost 40 million kilometers away from Venus, and at their current forward speed, it is estimated that it will take more than a month to finally enter the orbit of Venus.

When it reaches the orbit of Venus, they will control the asteroid to slow down. At that time, they can also finally obtain the desired theoretical results based on the performance of the aerospace aircraft at that time.

Whether they need support from other aerospace planes or aerospace fighters, they will know when the time comes. As for the high temperature of Venus reaching nearly 500 degrees Celsius, with the aerospace plane having a particle energy shield, the high temperature will It's not a big problem at all.

The month-long flight made the astronauts on the plane into boring time again. Fortunately, like the Mars exploration team, they brought many entertainment items before departure. It is precisely because of this that they did not let them get too excited. Too boring.

Apart from flying the aerospace plane, the five astronauts had no other tasks, but the scientist following the plane was trapped in endless thoughts.

The two asteroids they landed in the universe before, what they got from them are really valuable for research. Even if this scientist is just an astronomer, he can't stop him from analyzing the detected data. Do research and think.
