It was an unexpected discovery for them to find organic matter on an asteroid, although the amount of organic matter in this soil was very small, but it was a real organic matter.

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

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

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

With organic matter in the universe, coupled with a suitable environment, life may not be able to occur, such as the super earth discovered by geoscientists in the universe before.

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

In such a large cosmic space, there are planets with similar environments to the earth, and we don't know how many planets there are, even if we calculate with the smallest probability, we can conclude that human beings are not alone in the entire universe.

It is very likely that life has actually been produced on the previously observed super-earth, and even civilization has appeared on this super-earth, and it is very likely that their level of civilization is even higher than that of the earth.

The discovery of organic matter has made scientists think a lot, and even to some extent has given him a strong sense of urgency.

At this moment, they discovered the existence of organic matter on the asteroid, as long as this asteroid falls to the right planet in the future, by chance, under various chances, the emergence of life will be inevitable.

If there is really a particularly high-level civilization in the universe, if the other party discovers the existence of the earth, the emergence of a habitable planet like the earth is likely to cause covetousness.

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 the presence of organic matter on the asteroid, the astronauts immediately returned to the space plane and immediately engaged in a discussion about what they should do next.

And in their negotiations, the final fate of the asteroid they are on was also decided by them.

Eventually, these asteroids will be towed by them to the Earth in an aerospace aircraft, of course, this move is not to be carried out immediately, but after some experiments, they can ensure that they can really control the asteroid to land safely.

After finally discussing such a solution, they stepped out of the plane again and went on to gather more detailed information about the asteroid.

After they had collected all the information about the asteroid under their feet, and then recorded the coordinates of the asteroid, they set up an aerospace plane to leave the asteroid.

In the vast universe, the number of asteroids is extremely huge, just as people can't count how many hairs they have, the number of asteroids is also innumerable.

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

The asteroid they chose this time was actually not much different from the one they had just left in appearance, and it was also an irregular star with a diameter of more than a kilometer.

And in terms of volume, the asteroid they are targeting now is a little larger than the previous asteroid.

Then they will also land on their next targets as they did on the asteroid before, and after the successful landing, they will also collect information on these asteroids to see if there is anything on the asteroid that is particularly useful to Earth.

If there is nothing too important to discover, or the resources that Earth needs, then they will try to drag the asteroid to their nearest planet, Venus, and do an experiment on it.

That is, whether their aerospace aircraft can completely tow the asteroid, and their ultimate goal is to control the safe landing of the asteroid on the planet within a controllable range.

If they can control this asteroid and land on a planet safely, then the asteroid they discovered before, which contains a lot of rare earths and organic matter, can land safely on Earth under their control.

When an asteroid with a diameter of 1,000 meters, its final volume will reach 523.58 million cubic meters, and it is very likely that such a huge volume cannot be controlled by an aerospace aircraft at all.

What's more, the previous asteroid contains a large amount of rare earths, which are a material denser than earth, and his overall weight can be imagined, it will not be ordinarily large.

It's really not something that can be controlled by an aerospace aircraft, so it is necessary to carry out this kind of experiment for the sake of safety.

If you don't go to the experiment, you will really be like a stunned young man, dragging an asteroid with a diameter of a kilometer back to the earth, and if the space plane can't pull the asteroid at that time, the consequences will not be borne by human beings at all.

A long time ago, the overlord of the earth was still the dinosaurs, and although there is no conclusive conclusion as to why the dinosaurs became extinct in the first place, the conjecture of an asteroid impact is abnormally marketable.

An asteroid with a diameter of 1,000 meters was not pulled by the space plane, and finally hit the earth, and the earth will usher in a catastrophe.

The impact can cause large amounts of dust to enter the atmosphere, which can block sunlight for up to a year, and also cause large amounts of sulfuric acid to be present in the stratosphere in the form of aerosols, reducing the amount of sunlight reaching the surface by 10-20% and ultimately preventing plants from photosynthesis.

The complete sedimentation of these aerosols in the stratosphere will take up to ten years, which will lead to the disappearance of a large number of plants and phytoplankton, and the impact will be particularly huge.

And after the impact, there will be a large amount of infrared penetrating the atmosphere, causing damage to exposed organisms, and the impact will also cause a global fire storm.

If such a possibility really appears, then mankind will usher in the end of the world, and it is very likely that human beings will disappear from the earth like the original dinosaurs, and it is very likely that after 10,000 years, they will become fossils and oil like dinosaurs!

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

At that time, after the experiment, it would be best if the asteroid could be dragged back to Earth in a controlled manner, and if it could not be dragged back to Earth in a controlled manner, then they would have to carry out the second plan.

The second plan is definitely not as good as the first, that is, to build a large number of aerospace planes and space mining equipment, complete smelting and purification on asteroids, and transport a large number of useful finished materials back to Earth through aerospace aircraft, which is undoubtedly much more expensive.

Or they bombard and smash the entire asteroid with particle weapons, and end up with countless fragments, which they transport back to Earth in a variety of sizes and shapes.

Anyway, there are many options, but the option of returning the entire asteroid to Earth is the least costly one. If you think about it, you can know that an entire asteroid has been transported back to Earth, and when the time comes, people will not be able to mine it as much as they want?

The asteroid that was now their target was not far from where they were now, and they drove the space plane to its maximum speed, and it took more than a week for them to come to the asteroid as their target again.

After some series again, the same process as on that asteroid before, and finally landed on this asteroid.

After landing, various tests were carried out in an intense and orderly manner, and the various terrains and components of the asteroid were within the scope of their information collection.

Under all kinds of strict inspections, the asteroid they are on has been detected by them, and everything on the asteroid will be collected by them.

The composition of this asteroid is very different from the asteroid they detected before, or this asteroid is useless to human beings.

They drilled into the ground in the most concave part of the terrain, and went down a distance of more than 500 meters, which should have reached the core of the asteroid according to the factory.

But they all hit the core, and the material they detected was no different from the material detected on the ground, which means that the whole asteroid is the same type on the surface.

In the end, such a test result was obtained, so that is to say, this asteroid is of no use at all, and it has no use value for the earth and human beings.

This made the exploration team have a feeling of disbelief, knowing that the asteroid at this moment and the asteroid they had reached before, the gap was too big.

The previous asteroid can be said to be full of treasures, but the asteroid they are on now is useless, and the gap between the front and back is too big.

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

When they got the second asteroid they had reached, which had no use in the slightest, all of them looked at each other and made a decision.

The asteroid under their feet will exist as a prop for them in the future, and they will use this asteroid to test the towing technology of the space plane.

After the astronauts made a decision, they immediately used the anti-gravity technology of the space plane to start pulling the asteroid, and the engine was turned up to the maximum by them.

The orbit of the asteroid in space, under the traction of the space plane, began to slowly change, and they drove the space plane, pulling the asteroid with a diameter of 1,000 meters, and began to move towards the nearest planet to them.

The planet they landed on was Venus, the closest planet to Earth, and the second planet to start outward from the Sun. An inner planet located on the inner side of the Earth.

Venus is also a terrestrial planet that closely resembles Earth and is often referred to as Earth's sister star. It has the thickest atmosphere of the four terrestrial planets. Venus is also very similar to the Earth in terms of gravity, with the Earth's gravity being 1 g and Venus' surface gravity being 0.903 g.

It can be said that in terms of gravity, Venus is more to Earth than Mars.

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

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

At such an average temperature, it is undoubtedly a luxury for Venus to have higher organisms, and it is very likely that there will be some microorganisms on it, and no higher level of life will exist except for these microorganisms.

Speaking of returning to the task of towing and landing, with the continuous development of the aerospace aircraft in the universe, the speed of the asteroid is also increasing under the traction of the aerospace aircraft.

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 reach Venus before they can finally enter the orbit of Venus.

When it comes to the orbit of Venus, they will control the asteroid to slow down, and at that time they can finally come to the desired theoretical results based on the performance of the space plane at that time.

Whether they need the support of other aerospace planes or aerospace fighters, they will know at that time, as for the high temperature of Venus at that time, which is close to 500 degrees Celsius, under the condition that the aerospace aircraft has a particle energy shield, the high temperature is not a big problem at all.

The month-long flight made the astronauts on the plane enter the boring time again, but fortunately, before departure, like the Mars exploration team, they brought a lot of entertainment, and it was precisely because of this that they were not too bored.

In addition to piloting the space plane, the five astronauts had no other tasks, but the scientist who followed the plane was caught in endless thinking.

The two asteroids they had landed on in the universe before, and what they got from them was so valuable that even if the scientist was just an astronomer, it couldn't stop him from thinking about the data he had detected.
