The reason why I didn't go to the Xinyuehu Aerospace Command and Control Center, which is one step away, was because I was afraid of trouble. Why did I have to make a special trip to see things that I could see in the office?

The second one is because they will inevitably have an impact on everyone, especially this mission has attracted more attention, and everyone is under too much pressure. Wu Hao's going will undoubtedly increase everyone's pressure, so they simply don't go.

In the end, Wu Hao and the others were actually reluctant to go. Although this mission has attracted more attention from the outside world, it is an ordinary space launch mission for them, and there is no need to pay too much attention to it. So, they didn't bother to go, they just took a look in the office.

Seeing the rising rocket on the screen, everyone in the office smiled.

good!

clap clap...

Following Zhang Jun's applause, everyone present followed suit and applauded.

Seeing this, Wu Hao smiled and applauded with everyone. A good start is half the battle. The rocket ignited and launched very smoothly, which of course deserves everyone's joy.

In the video, everyone in the South China Sea Launch Command and Control Hall and Xinyuehu Aerospace Command and Control Hall are working in an orderly manner, and the radio in the hall broadcasts various data information from time to time.

Whether it is the staff of the launch site system or the staff of Haoyu Aerospace, everyone has experienced such launch missions many times, so they deal with it very calmly, calmly and professionally.

Through the high-definition surveillance camera of the stationmaster outside the rocket body, Wu Hao and the others can clearly see on the big screen that the rocket is rapidly approaching the ground.

As the rocket flew higher and higher, it finally became a bright spot in everyone's vision, shining like a star in the night sky.

And through the telemetry screen of Position No. 1, everyone can clearly see the whole picture of the rocket's flight on the screen.

Especially in the night sky, the wake of the rocket is like a trickle, very silky. This shows that the rocket motor is working properly, the motor is running very smoothly, there is no spotting problem.

In fact, people began to observe whether the rocket was working normally a long time ago. In addition to the sensors on the rocket itself, there is also ground telemetry observation.

In addition to observing the flight attitude of the rocket through telemetry observation, the most important thing is to look at the combustion and injection of the engine at the tail of the rocket. The operating state of the engine is directly related to the operating state of the rocket.

If there is a problem with the rocket engine, there will also be problems with the shape of the ejected tail flame, such as not being smooth enough, intermittent, or color changes, etc.

For some major space launch missions, more ground telemetry stations will be set up, and more telemetry ships will be dispatched to conduct relay observations on the trajectory of the rocket launch, so as to track and observe the flight status of the rocket throughout the process.

With the continuous growth and changes of the technical numbers on the big screen, the rocket launch finally ushered in the first critical node.

I saw the rocket exhaust flash on the infrared remote sensing screen a few times, and the rocket changed from a single two points to four bright spots all of a sudden. The brightest bright spot is still rising, while the remaining three bright spots are relatively weak and are slowly declining.

Booster separation, primary and secondary separation!

clap clap clap...

The staff in the two halls and I also applauded, and Wu Hao, who was watching in the office, also applauded.

"The ground recovery team reported that the grid wings of the core first stage rocket and the No. 1 and No. 2 boosters are open, and the landing status is normal, and the landing is proceeding according to the scheduled procedure."

As the sound of the broadcast sounded, the big screen also switched to add the images of the core first-stage rocket, the No. 1 and No. 2 boosters, and the landing site. This time, the core first-stage rocket and two boosters will land on the main landing field together, realizing the magnificent scene of three arrows landing together.

In order to be able to record this spectacular scene, the entire ground recovery team, including the propaganda department, added many camera positions on the ground, in order to be able to record the entire landing process.

In addition, the entire landing and landing process will also be broadcast live in real time, so that all the people watching the launch mission can witness this spectacular moment together.

On the other side of the picture, the second-stage rocket is pushing the Lunar Cargo-2 spacecraft to continue to take off. But because the height is too high, I can see a bright spot in the remote sensing picture at this moment, and the picture is very blurry.

As the rocket flew higher, the bright spot flickered for a while. The two halves of the fairing protecting it can be seen in the external surveillance camera of the lunar cargo spacecraft.

In the picture, the night hemisphere below, the arc-shaped sky in the distance, and the green aurora over the North Pole can already be seen.

"Throw the cowl!"

Position No. 1 reported that the two halves of the fairing at the front end of the second-stage rocket were successfully thrown out!

"good!"

There was another burst of warm applause in the command and control hall.

The so-called layman watches the excitement, while the insider watches the way. Throwing the fairing seems to be quite simple, but in fact the action of throwing the fairing occupies a very important part of the entire rocket launch. UU Reading www.uukanshu.com

In many cases of rocket launch failures so far, many of them were caused by the failure of the fairing to separate and eject on time.

The two halves of the fairing on Jianmu No. 9 are very large in size, so it is very difficult to separate them. This must require the entire separation mechanism to be reliable enough.

Despite this, the entire rocket launch team was still very worried at this time point, and it was not until the fairing was separated that it was a long sigh of relief.

The picture on the fairing was also worn back again. After the two halves of the fairing were thrown out, the paraglider inside the fairing was thrown out quickly, and began to drive the fairing to adjust its attitude and glide in the air.

The ground recovery team reported that the falling posture of the two halves of the fairing was normal, "The air recovery team has arrived in the predetermined airspace and is on standby, ready to recover!"

As soon as the screen changed, three yellow-painted helicopters were flying towards the predetermined sea area. This is the recovery team of the fairing, and they are responsible for the aerial recovery of the two halves of the fairing.

Different from other methods of recovering fairings, Haoyu Aerospace's recovery technology for fairings is more direct, even brutal. Use the helicopter to hang the hook, and then hook the paraglider on the fairing, and then realize the air recovery, air hoisting and transfer work.

This recovery method is more maneuverable, more flexible, and has a higher success rate of recovery. Of course, the risk brought by the advance payment is naturally higher than that of ordinary utilization ships, which use vehicles to open a large net to wait for the fairing to land.

Although the risk is a bit higher, it is not so high, and the cost of recycling in this way is lower, which is more important for fairing recycling.

If the success or failure of recycling is too high, then there is no need to spend this effort and take this risk to recycle.
