Movie black technology

Going to the moon does not have strict requirements on the launch window like going to Mars, because on a space scale, the distance between the earth and the moon is very close.

The average distance between the earth and the moon is 380,000 kilometers, and the distance between the moon's apogee and perigee is only 40,000 kilometers.

When chemically propelled rockets send the spacecraft out of Earth orbit, the flying speed is tens of thousands of kilometers per hour. At this speed, it is easy to fly to the moon, even the third brother can do it!

So it's not impossible for the opponent to block a time.

After guessing what the other person was thinking, the old man He Wei smiled even more happily, as if watching his son come back after marrying a beautiful wife.

With Chen Shen on the side, he had to remind him many times not to laugh too wildly, it would easily appear that they were villains.

The time came to nine o'clock in the evening.

In the school dormitory, Zhou Dafu, who watched Pleasant Goat and basketball all day, was completely immersed in it and couldn't extricate himself.

At this time, the live broadcast screen flickered, and it changed from the screen of Lan Yangyang shooting a basketball to an open field.

"Hey! Why is it gone!" Zhou Dafu and the roommates behind him all exclaimed at the same time.

Only then did he react.

"Is this going to take off?!"

Immediately, everyone forgot about Pleasant Goat and basketball.

Other viewers in the live broadcast room also reacted.

"Where's the big medicine? Why don't you bring it to me quickly?"

"Here it comes! The big medicine is here!"

"Who would have thought that for this moment, I watched Pleasant Goat all day!"

It started in less than ten minutes in the live broadcast room.

Gray on the other side has already received the news.

Looking at the screenshots of the overseas live broadcast room sent by his subordinates, he knew that the launch time on his side had been guessed!

At this moment, he really wanted to forget about this launch, so that he might be able to avoid the Tibetan antelope.

Anyway, this rocket has been pigeond so many times, and it is also a strong contender for the ace pigeon in the aerospace industry. If you pigeon this time, you will be forgiven, right?

Surely it will?

But the other side is so thick-skinned, he is worried that the other side will let the Tibetan antelope dove with SLS...

And there is pressure from the boss...

If he was a pigeon, he might become pigeon soup on the boss's table tomorrow night.

well!

Life is not easy!

"How about the final inspection?"

The subordinate next to him immediately replied: "It has been completed, this inspection is the highest standard inspection, and everything is in normal condition."

Gray opened his mouth, wanting to check again, but he looked at the time, and it was less than two hours before the launch, which was not enough time to check.

"Forget it, let's get ready for launch, we will ignite on time at 9:32."

Gray clenched his hands tightly. If this launch fails, he can imagine what kind of infamy he will bear—Waterloo in the space race, a traitor to freedom...

At that time, the crimson storm model bought by his grandson will become evidence of his collaboration with the enemy...

Although the SLS rockets use basically mature technologies, such as the engine, which was built a long time ago as a spare for the space shuttle, and now the space shuttle is gone, so it is taken out and installed on the rocket, which is regarded as waste utilization.

It stands to reason that this kind of rocket launch should be very safe, but it is normal for a rocket launch to have some accidents, and it is not normal if there are no accidents.

A complex system with hundreds of thousands of parts like a rocket, not all parts can work normally every time it is launched.

It is not uncommon for some parts to suddenly fail and fail to work during the launch process. It is not uncommon for a rocket engine to stop directly.

At this time, it can only be solved by the redundant design on the rocket. If there are spare parts that can't work, it will not affect the launch.

If you can't make it up, you can only borrow two Gs from the nine Gs of F16.

Moreover, some people believed ten years ago that the development speed of a rocket using mature technology like SLS should be very fast...

I can only sigh that things are impermanent!

In apprehension, the staff in the launch center got busy.

At the same time, when He Wei saw this scene, he immediately had the Tibetan antelope pulled out of the warehouse.

The door of the warehouse opened, and a huge tractor towed the traction platform, on which the Tibetan Antelope was slowly driven out.

Today's Tibetan Antelope has been specially painted in red, which looks very festive, with a little black in the middle, which is a bit cool.

Many people in the live broadcast room were watching the live broadcasts on both sides at the same time.

Everyone noticed the almost simultaneous movements on both sides.

"The smell of confrontation is too strong."

"It is recommended that the two sides fight after reaching space. Only standing spaceships are eligible to fly to the moon!"

"A small half-year-old spaceship on the opposite side came to attack me, a ten-year-old rocket, is that okay?"

Gray watched this scene with his own eyes, feeling extremely blocked in his heart.

However, there was no turning back when the bow was fired at this time, and he could only wait for the time to pass by, praying to God that there would be no problems with this launch.

Finally, the hands of the clock reached the scheduled 9:32.

Gray immediately issued a launch command, and at the same moment, the launch tower began to inject water into the diversion tank under the rocket.

In this way, it is to cool down the launch pad and the diversion tank, and secondly, it is to weaken the resonance phenomenon caused by the sound when the rocket is launched.

The sound will cause the vibration of the object. The greater the energy of the sound, the greater the amplitude of the forced vibration of the object. Once the limit is exceeded, the object can be destroyed.

The noise of a rocket taking off can reach 220 decibels, almost twice that of an airplane taking off. People can't survive a second in this noise, and most rocket components can't stand this noise.

So if it is not relieved by spraying water, it is estimated that it will be difficult for the rocket to leave the launch pad vertically.

On the other side, Chen Shen saw He Wei, a bad old man, immediately said into the microphone after the countdown started on the opposite side: "Hurry up and start the countdown, hurry up and catch up!"

Chen Shen became more and more speechless. The opposite must have saved the Milky Way in his previous life, so there must be such a person?

The countdowns started almost simultaneously on both sides.

The moment the countdown reaches zero.

Both sides ignited almost at the same time!

boom!

In Kennedy, the huge core-stage engine of the SLS was driven to maximum horsepower, and the fierce flames evaporated all the water in the diversion tank below. Then, in just a few seconds, the rocket rose from the ground like a second sun, Flying into space at great speed.

And in the country.

The thrusters of the Tibetan Antelope sprayed out plasma light, and it was slowly lifted into the air at this time.

Compared with the rocket, this half-year-old spaceship is like a slow little old man, taking his own crutches and setting off from the door of the house without haste.
