Although he was also worried that the proposal to "transport" the asteroid to the past could not be passed by the earth's side, Tang Feng still drove the Nautilus around the asteroid and took it away. Pen "Fun" Pavilion www.biquge.info

Earthlings are worried that these asteroids will be in danger, and Tang Feng is also worried, but it doesn't matter, it's a big deal not to transport these big guys to the Earth's orbit, they can be directly transported to the lunar orbit or the Martian orbit.

Of course, it would be better if a comet passed through the asteroid belt and was caught by Tang Feng. There is no water on Venus now, and the conditions are extremely harsh, and a comet with a sufficient equivalent amount is needed to hit the surface of Venus, so that a large amount of water vapor contained in the comet can remain on Venus, which can at least add a large "lake" of the Yellow Sea area to Venus. Moreover, comets also carry a huge amount of life factors, and they will also contribute to the transformation of the environment of Venus.

It's a pity that the comet can't be seen in the asteroid belt, and most of that thing originates in the far away Kuiper Belt or even beyond, and it really depends on luck if you want to run into that thing.

Moreover, in Tang's plan, once the Earth successfully implements large-scale migration to Mars and Venus, then the Earth, as the home planet, will slowly carry out the "de-industrialization" plan.

If the earth civilization wants to join the Star Alliance, then the home planet must become the most brilliant planet of the earth civilization. Those polluting industrial enterprises had better move to Mars, Venus, the moon and even other immigrant planets, and the earth, as the home planet of the earth's civilization, must become the best.

Of course, it will take a long time for this plan to be implemented. However, once the earth really joins the Star Alliance, the earthlings will definitely support this plan after seeing the home planet of the major families and civilizations of the Star Alliance.

Who doesn't want their home to be better, as long as there are conditions, no one wants to make their home the same as a kennel.

The powerful families and civilizations in the Star Covenant can be called against the sky for the protection of their home planet. For example, the lifespan of a star similar to the sun is about 10 billion Earth years, which translates into a star alliance year, which is about 1,000 star alliance years. At this point, the star will enter the end of its life due to the excessive release of its own energy, that is, the star system is about to enter the stage of decline.

At this time, as the home planet of those families and civilizations of the Star Alliance, these families and civilizations will use the super high technology of the Star Alliance to install a huge planetary engine on their home star, and then push their home star to the designated position.

This location must have been found for a long time, and it is definitely a star system in its prime, so that the parent star can continue to exist in this new star system.

The families and civilizations in the Covenant will use this method in order to preserve their home planet. At present, with the scientific and technological level of the earth's civilization, of course, this cannot be done, but if the earth's environment is improved, there is still no problem.

If the earth's civilization wants to develop for a long time, it is necessary to adopt this mode of preserving the home planet and carrying out various industrial production on other administrative planets. This model has been proven in the Star Alliance and is an excellent development model.

Of course, in order to achieve all this, it will take a long time for the earth's civilization to work hard.

But for now, start that effort on your own!

It is with this mentality that Tang Feng walked the entire asteroid belt and marked those asteroids that contain various rich mineral resources, although they were not directly controlled by the star core, but with these marks, it was enough for Tang Feng to carry out the transportation of these asteroids in the future.

In fact, if Tang Feng is willing, he can use the transportation function of the star core to control these asteroids, and then transport the mineral resources directly to the earth, just like when he transported helium-3 ore from the moon to the earth.

Stellar star cores do this kind of work, with ease.

But Tang Feng didn't want to do this, and the reason was actually very simple.

Human beings rely on their own technology to carry an asteroid, which has a huge role in promoting the entire space technology. As long as humans can accurately transport an asteroid to Earth's low Earth orbit, then building a super-large spacecraft for interstellar migration will not be a problem.

Because the engines used to propel and slow down an asteroid are used to deal with a spacecraft, and that's a drizzle. How big is a spacecraft? How much does it weigh? Compared to an asteroid, that's a big difference.

If the earth civilization wants to go out of the solar system and enter other star systems in the galaxy in the future, this super-large spacecraft is an indispensable equipment. Only when such a super-large spacecraft is completed can human beings truly enter the universe.

Of course, this process is long, and at the very least, it is absolutely impossible to eat a fat person in one bite. Therefore, Tang Feng also deliberately picked out a lot of relatively small asteroids during this inspection. Most of these asteroids are between tens and hundreds of meters in diameter, and super ion thrusters are perfect for testing various powers.

Through the conversation with Dr. Schmitz, Tang Feng has learned that now Dr. Schmitz's team has basically understood the manufacturing process of the super ion thruster with a diameter of more than 60 meters provided by Eric.

Compared to the state-of-the-art 1,800 mm xenon ion thruster used on the Prince Barnett, the technology provided by Eric is a higher grade plasma thruster. The unit thrust generated by this plasma thruster is even more powerful, or the earth civilization has not yet mastered the principles and technologies of more advanced magnetic thrusters, Eric will even provide Tang Feng with more powerful magnetic thruster technology.

However, even this plasma thruster technology, which has long been abandoned by the Star Alliance, far surpasses the technology of Earth. Although the earthlings have preliminarily mastered the relevant technology of plasma thrusters, they can be regarded as the first glimpse of the way, but if they want to manufacture this kind of plasma thruster with a diameter of up to 60 meters, they will have to wait at least thirty or fifty years.

Of course, Tang Feng wouldn't wait that long, so he asked for this plasma thruster technology from Eric's hands.

Just in terms of caliber, the 1800 mm xenon ion thruster used on the "Prince Barnett" is simply the difference between a needle and a towering tree compared to this super plasma thruster. Not to mention that the 1800 mm caliber xenon ion thruster only has a thrust of a few tens of kilograms, while the thrust of this super plasma thruster is as high as more than 100,000 N, that is, tens of thousands of tons of thrust, which is more than three times more powerful than the thrust of the most powerful Saturn V rocket engine on Earth.

Of course, such a large-caliber plasma thruster cannot be installed on a launch vehicle in any case, because there is no such thick launch vehicle that can install such a large-caliber thruster. Such thrusters can only be installed on large spacecraft. For example, a large spacecraft under construction for the settlement of Mars.

Of course, this plasma thruster can also be used to propel smaller asteroids if more than a few are installed on the asteroid...... (To be continued.) )
