Ballistic missiles are spectacular when they are launched, and rockets are not bad when they are fired.

The size of the ballistic missile is very large, and the momentum of the launch is basically the same as that of a rocket, and it plays the role of the final word, basically launching one, at most, it is with a nuclear warhead with a separate guide, and the accuracy is very good.

The size of the rocket is generally very small, at least much smaller than that of ballistic missiles, but it is never launched alone, and the launch base is according to the "car", one car by one, and ten thousand arrows are fired at once.

The "Hercules" thrusters ignited, and then relied on the force of recoil to reduce the speed of the "Tutadis" asteroid, and more than a dozen thrusters in its direction spewed hot flames at the same time, which was quite spectacular.

Although the audience can't see it all, the United States intimately invited the light magic special effects company to do an animation demonstration, and the effect displayed is extremely eye-catching.

On the seemingly ordinary asteroid, more than a dozen clusters of flames suddenly appeared on one side of the rock mass, and the background music that made the atmosphere more exciting enough to make the audience's hearts surge.

Well, that's the benefit of an animated presentation, which can be made into a sci-fi blockbuster.

Although the thrust of these dozen thrusters is not very large relative to the mass of the asteroid itself, it is impossible to make the asteroid brake sharply, but it does slow down its forward speed.

Due to the limited amount of fuel carried, it is not possible to spray all the time, so the deceleration of the asteroid will be divided into several times, and different data must be calculated each time to achieve the best deceleration effect, which cannot be completed in one day.

Knowing that people don't have that patience, Mi Guo let the public on the earth watch a prelude and the beginning, and almost turned off the live broadcast, and then directly put the video on the official website.

The post-animation demonstration and the real live video let people know that the United States has succeeded.

They successfully slowed down the "Tutadis" asteroid, and got out of the elliptical orbit around the sun, entered the orbit around the earth, and continued to circle towards the orbit of the earth's artificial satellite, and even soon surpassed the moon, becoming the first giant near-Earth asteroid so close to the earth and more than 4 kilometers in size.

After it crossed the moon, people began to look for it in space, whether it was a hobbyist looking for it with an astronomical telescope, a photo published by a private observatory, or an official organization, it could cause a warm response.

At this time, after a month's long journey, the "Voyage" Mars exploration spacecraft also approached Mars, and more and more videos and images were transmitted, which happened to collide with the final stage of the propaganda of the United States.

Up to now, it is not easy for the United States to pretend to be a comparison in front of the people of the world, how can it be possible for the Arc Group to compete in the heat of information, so it has invested a huge amount of money in public opinion propaganda.

After all, the highlight of Arc Spaceflight is to land on Mars, and at that time, the United States should be able to put the asteroid in the Earth's orbit safely, and the time conflict between the two sides is not very big, so there is no need to waste that money.

Originally, it would not take so long for the "Voyage" to fly to Mars, and it would arrive in 20 days during the best window, but unfortunately they missed that time, so now they have to fly for a little more than a month, which happens to coincide with the plan of the United States.

The main thing is that Dong Chen greeted the group, there is no need to stimulate the United States at this time, it is best to let them put "Tutadis" in the earth's orbit safely and securely, and the rest of the things will be talked about later.

After all, there is a game in this world called "I can't beat you, but I can pull you to finish playing", whether this is "intentional" or "unintentional", it is better to be careful.

This is also the reason why after many countries have nuclear weapons, everyone is calm and restrained a lot, because if you are in a hurry, no one can get better.

On the spaceship, Dong Chen's robot went online again to take a look at this beautiful Red Planet.

Although he himself drove his "Black Hawk" to find the space tunnel and passed by the orbit of Mars, the position of Mars was not very good at that time, and he could not see it very clearly.

During this period, he talked to Musk about the United States' plan to capture asteroids this time.

Although the spacecraft is getting farther and farther away from the earth, it is still able to access the Internet, but because of the satellite relay and the ultra-long distance, the delay is certain, but the signal is still quite good, and it is not a big problem to understand a little information on the Internet.

Even compared to Dong Chen's robot without any delay, it is still a bit heart-wrenching.

“…… This time, the United States has indeed made a lot of limelight, and the practical significance of transporting the asteroid to the Earth's orbit is also very great. ”

"After all, it has been wandering in the solar system for so long, and the four-year cycle of reincarnation will pass through the asteroid belt, and then bypass the sun and then pass the earth, and it will definitely be able to carry some other things on it, which is also very important for human beings to explore the universe."

"The feeling of being able to study the entire solar system at your doorstep should be pretty good, saving you time and effort."

"And there are many kinds of mineral resources above, which can also be of great help to the current country, which is very important for its scientific and technological upgrading and industrial development."

"Why didn't our group start first at that time? We should not have any technical limitations, in this way, this kind of thing that only does one thing, but has many benefits, belongs to our arc group. ”

Musk asked Dong Chen suspiciously, and the tone was quite "his own person".

"This ......" Dong Chen manipulated the robot and touched his chin, "You also said that our technology is advanced and there are no technical limitations, so mining asteroids is actually not very useful for us at the moment." ”

"We calculated that the cost of mining on the moon is no higher than the cost of mining an asteroid."

"Of course, this is mainly the reason why our current industrial coverage is only in the Earth-Moon system, it is not far away, and it is convenient to do anything, and if we go to the asteroid belt one day to develop, it will definitely be to mine the asteroid."

"And when it comes to studying the solar system, studying the universe or something," Dong Chen pointed to the "Yuanhang" spacecraft at his feet, "Aren't we doing it?" ”

"Rather than studying an asteroid and learning about other planets and space from the side, I would prefer that we can do field investigations, because the results are more accurate."

"We happen to have this kind of strength, we can go to Mars for scientific investigation, why do we want to capture an asteroid that has just passed next to Mars, and then go to the trouble of studying Mars from the side."

Well, Dong Chen's reason is really something that Musk can't refute.

When he just reacted, Dong Chen said another reason that he thought, "And the earth is a little dangerous now, I don't want to drag everything next to the earth, if I don't do it, I just find something to do for myself." ”
