Chapter 506: Earth-Moon Orbit Change
After this, ZT-9 will go through several key nodes.
Only by getting through these nodes can the success of the rocket launch be basically confirmed.
"Procedure turn - normal!"
"The remote sensing signal of the position is normal!"
"Position tracking is normal!"
"Radar tracking is normal!"
"The cabin is flying normally!"
The signals coming from the headphones showed that the performance of ZT-9 was perfectly in line with expectations.
At this time, the TV host was introducing various detailed information about ZT-9.
"Friends who are familiar with our aerospace industry should know that the ZT-9 is known as a 100-ton launch vehicle for low-Earth orbit. In fact, this statement is not only not an exaggeration, but in fact it is a little less."
"Strictly speaking, the near-Earth orbit carrying capacity of the Zhengtu-9 has reached about 150 tons. Even in lunar orbit, the carrying capacity of the Zhengtu-9 has reached as much as 50 tons."
"Such a powerful carrying capacity is far beyond any of our previous rocket models. Since we had no foundation in heavy rocket technology before, we can say that we started from scratch and achieved a leap in this technology."
At this moment, every audience watching the live broadcast of the ZT-9 launch was very excited.
"Such a large rocket can be launched just by saying so." Lu Zhiyao said.
Before they knew it, the rocket was no longer visible from the location where Xu You and Lu Zhiyao were observing.
At this time, Xu You should also return to the control room.
"Yaoyao, I'm going back to the control room first. You can continue with your work."
"Well, there's nothing much to see here. We can only watch the next scene on TV."
After returning to the control room, Xu You immediately resumed his work state, carefully observing the real-time images of ZT-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, the Zhengtu-9 will also separate the second and third stage rockets.
"According to our previous interview with the commander-in-chief, after the first stage rocket separates, in the next six minutes, the second and third stage rockets will complete the separation process in sequence. After the separation of all three stages of the rocket is completed, our spacecraft can successfully enter low-Earth orbit."
At this moment, hundreds of millions of viewers across the country were watching the flight of ZT-9 nervously in front of their screens.
Fortunately, the flight of Zhengtu-9 went as smoothly as expected, with the second and third stage rockets successfully separating.
After this period of acceleration, the speed of the spacecraft exceeded the first cosmic speed, and after deceleration and braking, it stably entered low-Earth orbit.
This means that the entire launch of the Zhengtu-9 rocket has been a success.
In the control room, the first wave of warm applause rang out.
We are all excited about this hard-won victory. Over the past 30 years, we have achieved a huge breakthrough in the field of aerospace.
From the initial carrying capacity of 300 kilograms to the current carrying capacity of 150 tons, every step forward requires tremendous effort.
And at this moment, we can finally announce with confidence that we also have the ability to launch a spacecraft to the moon.
After a brief applause, the tense and solemn atmosphere returned to the control room.
Simply sending a spacecraft into low-Earth orbit is far from a mission success.
Next, it is necessary to complete the spacecraft's orbit change and allow the spacecraft to enter the lunar orbit, which will mark the end of this mission.
"Although this is just an unmanned flight test, there are actually three dummies in the spacecraft. In order to simulate the actual manned flight scenario to the greatest extent possible, the three dummies are not only completely consistent with real people in terms of size and mass, but they are also wearing standard space suits."
As the host introduced the show, the scene of the three dummies appeared in the camera.
If you don't look carefully, it's really hard to tell the difference between these dummies and real people.
"This is a space suit that we specially made based on the harsh conditions on the moon . The main body of the space suit includes a helmet, torso, gloves, boots, and a life protection kit."
"For the helmet, we adopted the bionic design concept and designed a retractable helmet based on the characteristics of pangolins. The helmet is made using 3D printing technology. In addition to the communication components, the helmet is also equipped with an anti-suffocation system."
"The main torso is made of soft fabric and semi-rigid structure. This design can maximize the space agency's flexibility on the lunar surface. Its strong heat insulation ability allows astronauts to ensure their safety in ultra-high and ultra-low temperature conditions..."
The host introduced the structural characteristics, unique functions, etc. of each part of the space suit in turn, which made people marvel at the powerful technology of this space suit.
"After hearing this, you may ask, this mission is just to fly around the moon, not to land on the moon, so why do these dummies need to wear space suits?"
"In fact, I had the same question as everyone else at the beginning. However, after I talked with the staff of our aerospace institute, I found out the reason."
"It turns out that the reason for carrying out such a mission is not only to test the capabilities of the Zhengtu-9 spacecraft, but also that the spacecraft will serve as a 'backup warehouse' for us on the moon after entering the near-moon orbit. In case of special circumstances such as problems with the space suits, the space suits of these dummies will play an emergency role."
Because the space suits have been rigorously tested, the chances of problems are minimal.
Even so, it's always a good idea to be prepared.
Even though each space suit costs a lot, it is worth spending money here.
Unknowingly, the spacecraft was getting closer and closer to its predetermined orbit.
We are about to reach the next critical point - changing track.
The spacecraft needs to accelerate in low-Earth orbit, pass through the Earth-Moon transfer orbit, and enter the lunar orbit.
This process is also a huge test for the spacecraft.
"The spacecraft has entered the Earth-Moon orbit transfer mode!"
Following the commander-in-chief's order, the spacecraft's control center switched the spacecraft's flight mode.
Because the actual track change process is very complicated and there will be delays in signal transmission, the entire process is not manually controlled.
The next task will be a huge test for the spacecraft’s AI control capabilities.
