The Suzaku rocket launched this time and carried the first test satellite of our satellite system."

……

The interview with Qiao Ruida lasted for an hour. After watching this interview, tens of millions of viewers in the live broadcast room had a deeper understanding of Qiao Ruida and Ruida Aerospace. Then Du Qingqing interviewed Cao Yifei, the general manager of Ruida Aerospace, and two other engineers. The interview ended at lunch time, and the live broadcast room began to play a documentary about the development process of the Suzaku rocket. Qiao Ruida and Du Qingqing took advantage of this time to go to the cafeteria for lunch. The other employees were also divided into two groups, taking turns on duty, and went to have lunch.

While Qiao Ruida was having lunch, reporters from several TV stations and newspapers rushed to Ruida Space City and asked to enter the rocket launch site for interviews and filming. Cao Yifei called to ask for instructions. Qiao Ruida thought about it for a while and agreed to their filming and interview requests, but they had to pay attention to safety. So several professional cameras were added to the rocket flight control center and not far from the rocket launch tower. Some engineers and staff who had lunch and returned to the site were also caught by reporters for on-site interviews.

After lunch, Qiao Ruida returned to the rocket flight control center. At this time, there were less than 40 minutes left before the rocket launch. Qiao Ruida took a final look at the latest satellite cloud map sent by the Meteorological Bureau and confirmed that there would be no extreme weather over the space city that would affect the rocket launch in the next hour.

"30 minutes to prepare, open the last set of rotating platforms." As the command was issued, the second set of rotating platforms that connected the Suzaku rocket and the rocket launch tower slowly opened. At the same time, the pipelines for replenishing liquid methane and liquid oxygen, communication cables and power cables were also disconnected. At this point, the red and white painted Suzaku rocket was completely exposed in the live broadcast, and the red national flag and the four large characters "Rui Da Aerospace" on the simplified Chinese characters were so eye-catching.

"20 minutes to prepare, all employees at the launch site evacuate." Upon hearing this order, all employees in the launch tower, people close to the launch tower, including reporters and cameramen, evacuated and entered the nearby underground bunkers. Of course, the cameras set up on site and the drones flying in the air were not evacuated. Without them, there would be no way to record the rocket launch.

"10 minutes of preparation" With the issuance of this new command, the rocket launch reached its final moments. The staff on site held their breath, raised their spirits, and focused on their work at hand. At this time, Qiao Ruida came to the back row of the control center, which was the media seat, with reporters and photographers from several TV stations and newspapers. Among them were major national media such as CCTV and Youth Daily. Du Qingqing and two staff members from the logistics department also occupied a position, where they were broadcasting the rocket launch live. After Qiao Ruida's personal Weibo promotion in advance and the accumulation of live broadcasts in the previous few hours, the number of people watching the live broadcast online at the same time has now exceeded 2000 million, including some foreign netizens.

For this live broadcast, the logistics staff brought four high-definition cameras, two SLR cameras, and three modified long-endurance quadcopter drones from Beijing. Currently, two of these cameras are set up at the rocket launch site, one is placed on the rocket recovery platform, and one is placed here at the control center. All three drones are also launched and hovering at different heights and positions above the Aerospace City to take full-scale, multi-angle shots of the rocket takeoff scene. All the images captured by all these camera equipment are sent to the director via wireless data streams, and then after a simple switch selection, they are pushed to the official live broadcast room of Ruida Group and the live broadcast rooms of Tiantian Toutiao and Kuaipai software.

Qiao Ruida sat next to the director and watched the live broadcast on the screen with him. "There are a lot of people in the official live broadcast room, more than 1700 million, why are there so many people posting in foreign languages, are there foreign netizens in the live broadcast room?"

The director stared at the monitor and replied, "It's mainly your fans, Mr. Qiao, and users of Reda phones. I estimate that almost all of your fans, Mr. Qiao, who are online, have come here. In addition, we used the Reda phone platform to do a pop-up promotion, which attracted a large number of passers-by and netizens, which is why there are so many people. These foreign netizens were also attracted by the Reda phone push ads. The time we chose for this launch is not very good. If it was launched at night, the number of people watching the live broadcast would at least double."

The number of followers of Qiao Ruida's personal Weibo account has exceeded 5000 million, and Ruida mobile phone users also have tens of millions. These two platforms work together to advertise to attract more than 1700 million people to watch the live broadcast, which is normal. More importantly, the live broadcast content is the launch and recovery of the rocket. There are so many world firsts in this launch. All netizens who watch the live broadcast have a feeling of witnessing history. This is so attractive that almost no netizens who enter the live broadcast room leave.

"Space launches are based on launch windows. Opportunities are fleeting, and it is impossible to change the launch time for a better live broadcast effect. It is already very good to have 20 million people watching. At least after this live broadcast, our Ruida Aerospace has become famous."

"Including the live broadcast rooms on Toutiao and Kuaipai platforms, the total number of people watching the live broadcast has exceeded 2300 million. Mr. Qiao, with so many people watching, don't you feel any pressure? If the rocket launch fails, then our Ruida Aerospace will be embarrassed."

Qiao Ruida shrugged and said confidently, "It's impossible for it to fail. I know the performance of the rocket I made myself. The satellite carried in this launch test is only a little over two tons, which is far from the upper limit of the Suzaku rocket. Even if two of the five Magpie engines fail and only three can work normally, it is enough to send the satellite into orbit. The only thing I'm not sure about is the rocket recovery. The first-stage recovery is not a big problem, but the second-stage rocket recovery and re-entry into the atmosphere are too dangerous. Any mistake can cause the recovery to fail."

While Qiao Ruida and the director were talking quietly, the last ten minutes passed quickly and the rocket launch entered the most exciting countdown phase. Everyone at the scene, including Qiao Ruida and Du Qingqing, raised their heads and looked at the big screen in front of the flight control center.

"10, 9, 8, 7, 6, 5, 4, 3, 2, 1, ignite!"

With the final command, the five methane engines installed on the Suzaku carrier rocket ignited successfully at the same time, and five blue tail flames gushed downwards and hit the cooling water surface in the diversion trough. Under the scorching high-temperature tail flames of up to thousands of degrees, dozens of tons of fresh water evaporated in an instant, turning into water vapor all over the sky, gushing out on both sides of the launch tower, rushing out hundreds of meters before gradually dissipating. Within just three seconds after ignition, the Suzaku carrier rocket accumulated enough power to break free from the constraints of gravity with itself and the communication satellite, and slowly flew away from the ground. After taking off, it gradually accelerated and soon soared into the sky. Relying on two high-definition cameras at the rocket launch site and three drones for tracking and shooting. The process of the Suzaku rocket from ignition to takeoff, to slowly accelerating to takeoff, was fully presented to more than 20 million netizens in the live broadcast room. At that moment, the barrage and gifts in the live broadcast room disappeared for two seconds, and then suddenly broke out, almost covering the entire live broadcast screen. It even reached the point where it was impossible to watch the live broadcast normally without adjusting the density and area of ​​the barrage.

"Congratulations, congratulations, the first critical point ignition and takeoff were successfully completed!"

"As long as there are no problems during takeoff, the rocket launch is half successful."

"The technicians at Ruida Aerospace are really amazing. They have really conquered the methane space engine." "It's too early to say it's a success now. There are still four key nodes to go: the first and second stage separation, the second stage rocket ignition, leaving the atmosphere, and the separation of the rocket and the satellite."

"Didn't President Qiao say in an interview that the Suzaku rocket will have no problem completing the satellite launch mission? The difficulty lies in the recovery process."

In the live broadcast, the red and white painted Suzaku rocket was increasing in height and speed, and soon it was beyond the shooting range of ground cameras and drones. The on-site staff quickly switched the signal source and put the images collected by the optical tracking radar on the big screen.

"Takeoff time: 13:00:02:36 milliseconds."

"The optical radar tracking of Ruida Space City is normal, and the telemetry signal is normal."

"Procedural Turn"

About ten seconds after the Suzaku rocket was launched, the flight direction clearly turned, from flying directly upward to deflecting to the southeast at a certain angle. The reason for the turn is related to the orbit that the satellite needs to enter. As we all know, all of my country's territory is located in the northern hemisphere of the earth, and the navigation and communication satellite launched this time needs to operate in a geosynchronous orbit and be positioned above the equator. This determines that the rocket must deflect to the south at an angle to send the satellite over the equator. The tilt to the east is to make full use of the earth's rotation to accelerate the rocket and reduce the rocket's fuel consumption.

"Dongfeng, radar successfully captured the gaze, optical radar tracking is normal, and telemetry signal is normal."

"Weinan radar tracking is normal."

"Taiyuan USB radar tracking is normal."

"Qingdao, radar tracking is normal, telemetry signal is normal."

As the information was continuously reported, applause broke out at the scene. The carrier rocket successfully flew off the ground and entered the high altitude, which at least proved that the take-off and low-altitude flight phases had been successful. The methane space engine was really able to generate a huge thrust of dozens of tons and push the rocket off the ground.

After the successful takeoff, the next key node is the separation of the first and second stage rockets. If it is a general carrier rocket, the first and second stage rockets are separated using explosive screws, which are simple and quick with a very low chance of error. However, the Suzaku rocket is a recyclable rocket, and most of its parts need to be recycled and reused, so the simple and crude separation method of explosive screws cannot be used. On the Suzaku rocket, the connection of these detachable mechanisms uses a mechanical locking device. After the carrier rocket reaches the specified altitude, the program will automatically open the locking device, and then the first stage rocket engine will shut down, and each will give the first and second stage rockets thrust in opposite directions, so that the first and second stage carrier rockets can separate. Then the second stage rocket will ignite and relay to send the satellite into space, and then the first stage rocket will enter the recovery stage. The high-altitude environment is complex and harsh, and vibration during flight is inevitable. Whether these mechanical locking devices can withstand the test and maintain normal working conditions depends on this rocket launch test.

One minute after the Suzaku rocket flew, it was out of the capture range of the optical radar. The image in the live broadcast room also switched to the rocket flight animation demonstration interface prepared in advance, and the real-time flight altitude and speed of the rocket were marked with numbers. In the lower right corner of the live broadcast screen, a small window was opened to play the real-time scene captured by the camera at the tail of the rocket. Although the image is a bit blurry due to the limitation of camera pixels and insufficient signal return bandwidth, the blue wake of the engine, the rapidly shrinking ground buildings, grasslands and white clouds can still be seen clearly.

“Primary and secondary separation”

After the Suzaku rocket had been flying for nearly three minutes, it reached an altitude of more than 80 kilometers above the ground. At this time, the fuel of the first-stage rocket was about to run out, and it finally reached the critical node of the first and second-stage rockets to separate. The live broadcast screen also switched to the signal of the camera at the tail of the second stage. At this time, the picture captured by this camera was still dark. However, as the "first and second stage separation" command was issued, a buzzing sound of motor rotation and a click sound of some mechanical device running rang out in the live broadcast room. Then a ray of light appeared in the live broadcast screen, and then the light quickly expanded. The image of the first-stage rocket appeared in the center of the screen, and quickly moved away, and finally turned into a small dot in the screen. At this time, the entire live broadcast screen was occupied by the beautiful earth. The blue was the sea, the white was the clouds, and the green and gray were the land. No matter when and where, seeing the colorful image of Mother Earth is always particularly exciting.

"The first and second stage rocket separated successfully, the second stage rocket ignited, and the second stage rocket ignited successfully."

In the live broadcast, some white gas was ejected from the engine bell mouth, and then a few sparks flashed, and the white gas was successfully ignited, ejecting a long blue tail flame, and a few beautiful Mach rings were faintly visible. In the flight control center, warm applause rang out again. The first and second stage rockets separated successfully, and the second stage rocket was ignited successfully, which means that this rocket launch has passed two key nodes and has taken another big step towards success.

"Dear viewers in the live broadcast room, as you can see, the first and second stages of the Suzaku rocket have successfully separated." (End of this chapter)
