Of course, the main reason is that just choosing a rocket launch base at the equator cannot qualitatively improve the rocket's carrying capacity.

On the original basis, increasing by a few percentage points will not solve the fundamental problem.

However, if the idea is bolder, it may completely change the situation.

"Launching a rocket from the moon makes it easier for the spacecraft to reach the expected speed, so that asteroids with a diameter of more than one kilometer can be greatly affected. Moreover, because the gravitational force on the moon is very small, it can make the same rocket have greater payload capacity."

Compared with launching rockets on Blue Star, launching rockets on the moon has many advantages.

The first advantage is that there is no atmosphere on the moon, so there is no air resistance, which will make the take-off process of the rocket very easy after launching on the moon.

The second advantage is that the first universe on the moon is very low, only 1.7 kilometers per second, which is about a quarter of that on the blue star, making it easier for spacecraft to enter orbit.

The third advantage is that since the moon revolves around the blue star, in this way, as long as the rocket is launched at the right time, a greater relative speed can be generated between the spacecraft and the blue star.

In addition, there are many other advantages of launching rockets on the moon, such as less space junk around the moon and so on.

Of course, at the same time, launching rockets on the moon also has many disadvantages.

Including that there is no oxygen required for fuel combustion around the moon, less suitable launch time, and so on.

And the most important point is that the moon has not yet been developed at this time, and there is no rocket launch base at all.

It is almost impossible to establish a rocket launch base on the moon within a year.

However, this did not make Xu You give up the idea of ​​​​building a rocket launch center on the moon.

"Even if it can't be completed within a year, this project should start sooner or later. In the future, there will be more asteroids that may approach the blue star, and if you want to explore farther outside the earth, it is definitely more important to launch a rocket on the moon." Good choice." Xu You thought.

According to the current data, the probability of these three asteroids finally entering the low-earth orbit is very small. Even if they do enter the low-earth orbit, with the current technological capabilities, it is enough to ensure the safety of Blue Star, but there will be Just some side effects.

Launching a spacecraft on the moon, colliding with an asteroid through the spacecraft, and changing the trajectory of the asteroid can be regarded as an alternative.

After a detailed evaluation, Xu You has determined his own plan, and stated his plan with everyone at the meeting.

"My idea is that after the next lunar landing project starts, we will build a rocket launch base on the moon and use the launched spacecraft to collide with asteroids. Launching rockets on the moon will not only allow the spacecraft to reach a higher level. The high speed can also increase the load weight at the same time, so that the spacecraft has the maximum momentum. In this way, even if the asteroid with the largest mass enters the low-Earth orbit, I am confident that the impact of the spacecraft can be used. Let's make it work like a blue star."

After hearing Xu You's idea, everyone looked at each other in blank dismay, as if they had some doubts about Xu You's idea.

"Academician Xu, are you sure that we can successfully build a rocket launch base on the moon before the three asteroids approach the blue star?"

After everyone hesitated for a while, one person raised his question first.

And now is also a question for most of the people present.

With our current aerospace technology, it is indeed possible to send astronauts to the moon, but to complete tasks of this level, it is not just as simple as sending astronauts to the moon.

You know, even if it is to establish a rocket launch base on Blue Star, it may be a problem in a year.

There are very few countries in the world that are capable of doing this.

"No, I didn't say that the construction of the lunar rocket base must be completed before the three asteroids approach the blue star. It is naturally best if it can be completed, and it doesn't matter if it cannot be completed. In any case, we will definitely not Let the asteroid really hit the blue star."

Hearing what Xu You said, some people already understood Xu You's thoughts.

"Academician Xu means that this is just an ideal plan, we just try our best to do it, and it doesn't have to be used for the three asteroids that will approach Blue Star in a year's time?"

Xu You also laughed when he heard the words:

"Yes, that's what it means. If it can be used a year later, that's naturally the best. If it can't, it doesn't matter. When it can be built, we will do our best."

After listening to Xu You's explanation, everyone was relieved.

Xu You continued: "Of course, this does not mean that we have sufficient time to prevent possible asteroid problems in the future. In this plan, we must go all out. This is not just for these three asteroids , including larger and more threatening asteroids that may appear later.”

Xu You knew that about 65 million years ago, an asteroid with a diameter of about 10 kilometers visited the blue star and had a huge impact on the blue star.

And this is probably the reason that led to the extinction of dinosaurs.

"With our ability to explore the moon, it is indeed not an easy task to establish a rocket launch base on the moon. Of course, at the same time, because the moon is still in the initial stage of development, the rocket launch base we have established on the moon, A lot of unnecessary parts can be saved, and there is no need to take a lot of protective measures like on the Blue Star."

When launching a rocket on Blue Star, it is necessary to take into account the various impacts of the rocket on humans, including the landing position of the rocket wreckage, etc., all of which require accurate calculations, and must land in an uninhabited area.

There are no living things on the moon. In contrast, there are much fewer places to pay attention to.

It can be said that as long as the most basic ability of rocket launch is available, other parts can be considered later.

Next, Xu You continued to explain his detailed plan, including the batches of rockets to be launched on the moon, the personnel and materials carried, the improved version of the lunar rover and drone, the location of the rocket launch base, the launch time, etc. , every detail was taken into consideration.

For Xu You like this, everyone could only nod their heads repeatedly. Apart from respect, they couldn't find any other words to describe him.
