After that, Journey No. 9 will go through several key nodes.

Only by surviving these nodes can the success of the rocket launch be basically determined.

"Procedural turn - normal!"

"The position remote sensing signal is normal!"

"Position tracking is normal!"

"Radar tracking is normal!"

"The flight in the cabin is normal!"

The signals coming from the earphones indicate that the performance of Zhengtu No. 9 is perfectly in line with expectations.

At this time, the host of the TV station was introducing various details about Zhengtu No. 9.

"Friends who understand our aerospace industry should know that Zhengtu-9 is called a 100-ton low-earth orbit launch vehicle. In fact, such a statement is not only not an exaggeration, but in fact it is a little less."

"Strictly speaking, the low-earth orbit carrying capacity of Zhengtu-9 has reached about 150 tons. Even in lunar orbit, the carrying capacity of Zhengtu-9 has reached as much as 50 tons."

"Such a powerful carrying capacity is far beyond any of our previous types of rockets. Since we did not have any foundation for heavy-duty rocket technology before this, it can be said that we realized this technology from scratch. leap."

At this time, every viewer who watched the live broadcast of the launch of Zhengtu No. 9 was very excited.

"Such a big rocket will go up if you say it goes up." Lu Zhiyao said.

Unknowingly, the shadow of the rocket was almost gone from where Xu You and Lu Zhiyao were observing.

At this time, it was time for Xu You to return to the control room.

"Yaoyao, I'm going back to the control room first, you can go on with your work."

"Well, there is nothing to see here, and the next scene can only be watched on TV."

After returning to the control room, Xu You immediately resumed his working status, carefully observing the real-time screen of Zhengtu No. 9 and various data indicators.

Just now, Zhengtu 9 has passed the first critical node and successfully completed the separation of the first stage rocket.

Next, Zhengtu 9 will also separate the second and third stages of the rocket.

"According to our previous interview with the commander-in-chief, after the separation of the first-stage rocket, in the next six minutes, the second-stage and third-stage rockets will complete the separation process in turn. After completing the separation of all three-stage rockets, Our spacecraft can successfully enter low-Earth orbit."

At this time, hundreds of millions of viewers across the country were nervously watching the flight process of Zhengtu 9 in front of the screen.

Happily, the flight process of Zhengtu 9 was as smooth as expected, and the second and third stage rockets were successfully separated.

After this period of acceleration, the speed of the spacecraft also exceeded the first cosmic speed, and after deceleration and braking, it entered the low-Earth orbit stably.

This means that the entire launch of the Zhengtu No. 9 rocket has been a success.

In the control room, the first wave of warm applause sounded.

Everyone was very excited about this hard-won victory. In the past 30 years, we have achieved a huge breakthrough from scratch in the aerospace field.

From the initial carrying capacity of 300 kg to the current carrying capacity of 150 tons, every step forward requires great efforts.

And at this moment, we can finally announce openly that we also have the ability to launch an aircraft to the moon.

After a short applause, the tense and quiet atmosphere in the control room was restored.

Simply sending the vehicle to low Earth orbit is far from a mission success.

Next, it is necessary to complete the orbit change of the aircraft and let the aircraft enter the orbit around the moon before this mission is considered to be over.

"Although this is just an unmanned flight test, in fact, there are three dummies in the spacecraft. In order to simulate the real manned flight situation to the greatest extent, these three dummies are not only the size, quality and other conditions, but also The ones that are exactly like real people even wear standard space suits."

Accompanied by the host's introduction, the scene of these three dummies appeared in the camera.

If you don't look carefully, it's really hard to see the difference between these dummies and real people.

"This is a spacesuit specially made by us according to the harsh conditions of the moon. The main body of the spacesuit includes a helmet, torso, gloves, boots, and life protection bags."

"For the helmet, we adopted the design idea of ​​bionics, and designed a helmet with retractable function according to the characteristics of the pangolin. The helmet is prepared by 3D printing technology. In addition to the communication components inside the helmet, it is also equipped with anti-suffocation system."

"The main torso part is composed of soft fabric and semi-rigid structure. This design can maximize the guarantee that the space agency can carry out flexible activities on the surface of the moon. Its strong heat insulation ability allows astronauts to operate in ultra-high temperature and ultra-low temperature. Under the conditions, you can guarantee your own safety..."

The host introduced the structural characteristics and unique functions of each part of the spacesuit in turn, making people marvel at the powerful technology of this spacesuit.

"After listening to this, you may ask, this mission is only to fly around the moon and will not land on the moon, so why do these dummies still wear spacesuits?"

"Actually, at the beginning, I had the same question as everyone else. However, after I chatted with the staff of our aerospace academy, I realized the reason."

"It turns out that the reason why such a mission is carried out is not only to test the capabilities of Zhengtu-9, but also to serve as our 'backup warehouse' on the moon after entering the near-moon orbit. In case In special cases such as problems with space suits, the space suits of these dummy people will play an emergency role."

Because the spacesuit has been rigorously tested, the chances of something going wrong are extremely slim.

Even so, it’s always okay to be prepared.

Even if the cost of each space suit is high, it is worth spending money in this place.

Unknowingly, the spaceship is getting closer and closer to the predetermined orbit.

We are about to reach the next critical point - the change of track.

The spacecraft needs to accelerate in low-Earth orbit, and enter the lunar orbit through the Earth-Moon transfer orbit.

This process is also a very huge test for the spacecraft.

"The spaceship has entered the earth-moon orbit change mode!"

Following the commander-in-chief's order, the control center of the spaceship switched the flight mode of the spaceship.

Because the actual track changing process is very complicated, and the signal transmission will be delayed, the whole process is not manually controlled.

The next work will have a very big test for the AI ​​control ability of the spacecraft.
