Chapter 3217 Embark on a journey from month to month
【Revision】
Huge flames erupted from the tail engine of the Jianmu-9 heavy-lift launch vehicle, shaking the air like a dragon's roar. Supported by clouds and mist formed by huge water vapor, the rocket slowly lifted off.
Through the images returned by the high-definition camera installed on the launch tower, people can clearly feel the huge power generated at the moment of launch of the rocket. Even in the launch command and control hall a few kilometers away, Wu Hao and others can feel the rocket
A huge roar came from the launch.
This is the roar of the rocket. This sound is enough to tear the air and make people within a few kilometers feel the vibration. With the command of "Program Turn!", the rocket begins to adjust its angle, like an arrow piercing the clouds.
Pierce the sky.
At this moment, the people who were watching the live broadcast in various viewing areas were able to see the rocket launch as they wished, and they cheered loudly.
The huge roar of the rocket was accompanied by vibrations, which made the onlookers deeply feel the energy of this behemoth. This kind of shock can only be truly experienced by visiting the scene in person. Every tourist watching showed excitement, and even some
The person was shocked by the huge roar emitted by the rocket, and could not recover for a long time.
In the launch command and control hall, all staff are busy in an orderly manner, and various data and information are constantly updated and broadcast.
"Position No. 1 reports that the rocket tracking is normal and the telemetry signal is normal."
Although such launch missions have been carried out many times, they still require full concentration every time.
Although this mission is quite special and important, for the launch team with excellent professional skills and rich experience, they become particularly calm and calm once they get into work. The look of having everything under control makes everyone look very happy.
Peace of mind.
Wu Hao and Lin Wei, who were sitting in the guest seats, were also very excited. Lin Wei made trumpets with her hands in front of her mouth and cheered. She was as excited as a little girl.
In the starry night sky, the Jianmu-9 rocket was carrying the returnable lunar experiment spacecraft as it flew higher and higher, and finally turned into a bright and twinkling star in the sky.
On the large screen in the command and control hall of the Nanhai Launch Site, everyone can clearly see its real-time infrared signal image through the remote sensing data signal of Zhanjian-1.
The rocket is still flying stably. Through the infrared remote sensing signal picture, you can see that the wake ejected by the rocket is as smooth as wire drawing - this is the normal working state of the rocket engine. This picture also shows that the rocket engine is very stable during operation and combustion.
No fluctuations occurred.
The digital timer next to the big screen is still changing, and everyone is holding their breath waiting for the arrival of the first important node.
As the rocket tail flame flickers in the infrared picture, the rocket changes from the three tail flames that were gathered together to three scattered tail flames. The brightness of the tail flames on both sides is much weaker than the bright spot in the middle.
"Booster separation!"
"First and second level separation!"
The guests who heard the radio broadcast applauded enthusiastically and cheered.
The screen in front of the hall was divided into two parts: the screen on the left showed the upward-flying Jianmu-9 core two-stage rocket and the fairing payload it lifted; while the screen on the right showed three bright spots -
—This is exactly the flame emitted by the separated core first stage rocket and two boosters.
Through the surveillance cameras installed on the core first-stage rocket and the booster, people can very clearly see the wonderful moment when the first and second stages of the rocket separate from the booster: after the core first-stage rocket and the booster separate, the engine
The flow is closed and the grid wings at the front end are expanded to control the falling posture of the core rocket body by continuously adjusting multiple surfaces.
The tourists who gathered around the Nanhai launch site to watch the launch also witnessed three light spots beginning to fall downwards and burst into warm cheers again.
On the left side of the large screen in the command and control hall, there is a picture of the second-stage rocket pushing the return-type lunar experiment spacecraft to continue to soar upward; however, at this moment, the Zhanjiang-1 remote sensing equipment can only capture a faint bright spot, and the picture is starting to become blurry.
stand up.
Suddenly, the front end of this pillar-shaped bright spot flashed, and two objects fell off from the bright spot; the external surveillance camera on the return-type lunar experiment spacecraft in the fairing also captured this scene: the camera's picture froze for a moment and then was blocked.
The white objects in sight were thrown away and the entire field of vision became completely black."
Throw the fairing!”
Immediately afterwards, a report came from Position No. 1: "Position No. 1 reported: The two halves of the fairing at the front end of the second-stage rocket were successfully thrown!"
"good!"
Everyone was relieved to hear the good news and burst into warm applause and cheers again.
Warm applause erupted again in the command and control hall, and even some experts who were usually serious and reserved had rare smiles on their faces at this moment, and they all applauded together.
As the saying goes, laymen only watch the excitement, while experts watch the door. The action of throwing the fairing may seem simple, just throwing out the two halves of the protective shell, but it occupies a crucial part in the entire rocket launch process.
In fact, in many cases of rocket launch failure, the failure of the fairing to be separated and thrown out on time is one of the important reasons for the launch failure.
If the fairing does not separate successfully, the rocket will push the fairing and its wrapped payload into space. This means that the payload inside the fairing, such as satellites or other spacecraft, will not be able to deploy the solar wing battery sails for charging.
It was also unable to adjust its flight attitude, which ultimately led to the failure of the entire mission.
This time, the huge fairing of more than 20 meters high on Jianmu-9 was successfully separated and thrown out, which undoubtedly made the rocket team breathe a sigh of relief.
Although they have conducted countless tests and drills before, no one can guarantee the results until the last moment. After all, there are too many unpredictable factors in actual flight missions.
"The air recovery team reports that the air formation has arrived in the predetermined airspace and is on standby, and the high-altitude drones have begun to transmit back images!"
As the report came from the command and control hall, everyone's eyes focused on the big screen again.
The core two-stage rocket is pushing the returnable lunar experiment spacecraft to continue flying. After the fairing is successfully thrown away, the picture returned by the spacecraft's external camera instantly becomes brighter. At the edge of the arc skyline, a dazzling light gradually appears.
, that is the sun.
At the same time, the core first-stage rocket and booster on the other side are also slowly descending.
As their altitude continues to decrease, the intensity of the injection from the booster's tail engine gradually increases, and the sound becomes more and more deafening.
However, this did not affect the enthusiasm of the audience. Seeing the spectacular scene of three rockets falling from the sky, everyone cheered and marveled.
Amid everyone's attention and cheers, the core first-stage rocket and two boosters landed smoothly on the two circular landing platforms at the landing site in a "pin"-shaped array.
What followed was deafening cheers and applause, and the atmosphere reached its climax tonight.
