Siheyuan: Xu Damao, I want to go to the moon

Luna 2 was originally a lunar probe launched by the Soviet Union on September 1959, 9. It made a hard landing on the lunar surface on the 12th, becoming the first messenger to reach the moon, but its radio communication device stopped working after hitting the moon.

Now it is the launch date of the 24th, and the 26th is about to arrive, but Xu Damao has been waiting here for a long time.

[Electromagnetic cannon is charged to 100%, and three electromagnetic cannons can attack three times. The target distance is 3 kilometers, and the electromagnetic cannon attack range is 3137 kilometers. However, due to the vacuum and the influence of the earth's gravity, the shells can continue to fall at an accelerated speed. ]

[It is expected that the shell will automatically burn and decompose and disappear after entering the atmosphere about 10 kilometers. ]

[Host, do you want to shoot now? ]

Xu Damao was wondering about the attack range of the electromagnetic gun. Why was it so large?

I heard in my previous life that it was only about 200 kilometers? How come it is 2000 kilometers now?

Only then did I realize that we were now on the moon, in a vacuum environment with no air resistance, so it would naturally be much farther.

As for whether the target could be hit beyond the range, it was also clarified. The last time, the distance of Luna 1 was more than 5000 kilometers. It was only by relying on the stone and dung fork to move at a constant speed without resistance in the universe that it "collided" with the target, rather than hitting it directly.

How is it possible that a stone and a dung fork can be thrown more than 5000 kilometers?

Only on the moon can Xu Damao do this.

In addition, the shells are made of tungsten metal, 20 kilograms of pure tungsten metal, and they do not pursue explosive effects, but only pure kinetic energy strikes.

Therefore, after such a "small" piece of tungsten enters the atmosphere, it will be naturally decomposed due to its speed, just like a meteor.

Xu Damao even thought, if my shells were bigger and heavier, for example, if they were made into the shape of a spear, could they become "space-based" or "moon-based" weapons?

The system's answer is that it is not possible for the time being. The current electromagnetic gun is a lunar defense electromagnetic gun and does not have that much power.

That's a shame, but it's safe.

Therefore, Xu Damao ordered a test launch at the Lunar 2 satellite that was "colliding" with him at a high speed, and then corrected and determined the position and angle, etc.

So far, no shot has been fired, and Xu Damao also wants to see the effect.

There was not even a sound. The No. 1 electromagnetic cannon vibrated violently, and a lot of lunar soil was blown up. Then a shell was fired. If Xu Damao's eyesight had not been modified and there was a flash of lightning when firing, he might not have been able to see the shell. It was too fast.

Finally, only a slight vibration was felt under my feet.

Then, Xu Damao looked up and followed the trace of the shell. The speed of Luna 2 was 3.3km/s, while the speed of the electromagnetic shell was 2.5km/s. Logically, if it hit the target, there should be results within 9 minutes, but when the time was up, the satellite did not explode.

It must have missed the target.

In Xu Damao's eyes, the satellite is just a small black dot. If the earth was not behind it and on the bright side of the day, it might not be visible.

And the shells - I really can't see them.

[Missed, correcting the shooting parameters, do you want to shoot a second time? ]

"shooting!"

All that is consumed is electricity. These solar arrays plus the power storage center are enough for three electromagnetic cannons to fire six times a day.

As for the artillery shells, they are made from local materials and decomposed and synthesized by the quenching and decomposition center, and no gunpowder is required.

If the system can adjust the shooting parameters, it will be much more convenient in the future. Why not shoot?

So, the second shell was fired, and at this time, the first electromagnetic cannon was once again fully charged and was in position, ready to fire at any time.

But more than 3 minutes later, Xu Damao saw a small bright spot flash in the universe -

The satellite exploded!

Only then did he feel relieved.

"System, directly set 5000 kilometers as a defense zone. If anyone crosses this line, attack directly."

"5000 kilometers is the air defense red line of our lunar base! It is the distance of our airspace."

[As you command, host. ]

Xu Damao gave the order. This time, a test firing was needed and the shooting parameters needed to be adjusted, so he was quite nervous.

But after the test launch is completed and adjustments are made, the subsequent defense work will be carried out automatically by the system.

As for whether Xu Damao's decision is overbearing or not? Is the 5000-kilometer airspace reasonable?

The moon is 36 to 40 kilometers away from the earth. Damn, you insist on getting so close to me. Who else should I hit if not you?

The remaining distance is enough for you to launch a satellite.

When we can evolve the electromagnetic gun again in the future and its range is longer, we can adjust the defense line distance.

As for space-based or moon-based weapons, Xu Damao really wants to make one, which is equivalent to nuclear deterrence.

But there is no need to think about this issue now, it is too far away.

----------------

A few days later, the international news broke.

"Lunar 2 was attacked and crashed" -

There Are Aliens on the Moon

"The final image confirms that the lunar civilization is suspected to have an electromagnetic cannon" -

"Mao Xiong and Da Piaoliang jointly announced again to jointly develop the Lunar 3 lunar landing plan" -

"Is lunar civilization a threat to us?" -

"Baiyujing, do ancient Chinese myths and legends really exist?" -

"Xiao Rizi announced that according to the archaeological evidence of the Tale of the Bamboo Cutter, he has legitimate territory on the moon..." -

South Korea says ownership of the moon needs to be studied

"The Moon Belongs to All Mankind..."

"Moon……"--

Anyway, there were all kinds of things said, and some international news was quoted and published in domestic newspapers. In the Propaganda Department, Section Chief Huang, Xu Damao and others were watching the current affairs news and they didn't know whether to laugh or cry.

The Russian bear is unlucky. Its satellites were shot down twice. It is obvious that there are people on the moon and they are not allowed to go there. This is a typical example of not welcoming you.

But you still want to go, who else should I beat if not you?

Xiao Ri Zi and South Korea also jumped out to show their presence... Isn't this just looking for trouble?

The Russian bear just can't find anyone to get angry at.

"Electromagnetic gun? What is an electromagnetic gun?" Section Chief Huang was very interested in this.

"To put it simply, it uses electricity to drive metal shells. It's no different from an electromagnet, just an oversized electromagnet." Xu Damao explained casually.

Director Huang's eyes sparkled - "Da Mao, do you understand?"

"A high school physics experiment, very simple?" Xu Damao didn't understand why Director Huang was interested in this.

"So, let's make it for fun?"

"Have fun?"

As expected, no man is immune to guns and other weapons, let alone Director Huang who has retired from the army.

So, a group of old men with nothing to do decided to develop their own electromagnetic gun at the steel rolling mill. As they worked on it, the business became bigger and bigger.

"Chief Xie, we are applying for a cannon. We don't need shells, but only a long-barreled cannon."

As soon as he said action, Lao Huang ran to find Chief Xie of the Security Department excitedly and said, "First of all, you need a sturdy and durable gun barrel, right?"

Then, Section Chief Xie became nervous.

The 10th anniversary National Day military parade is coming up soon, and you are asking me for artillery at this time?

What are you going to do?
