I ask you to build tractors, but you build rockets?

In the South China Sea, the receiving antenna of the Yuanwang-1 radar survey ship rotated slightly, aiming to lock the first stage of the Xinyuan-2 that was already in space.

She sends the measured altitude, speed, attitude and other data to the communication satellite through the satellite antenna, which is then received by the ground base station in Qiongzhou and reflected on the simulated attitude image.

It is good to be included in the national aerospace measurement and control system. The rocket can be monitored in all aspects without blind spots, and the ground can conduct two-way verification based on the data sent by the rocket itself and active detection.

The audience on the beach still hasn't dispersed. They all know that the Xinyuan-2 mission will carry out a first-level recovery, which can also be seen here.

The audience waiting for recovery on the beach looked around and found something wrong with the launch station opposite, or next to the launch station to be precise.

Hasn't the rocket been launched? Why does it still seem to be smoking?

"Fight the fire, put out the fire! The excavator rushes to dig the isolation belt. How long will it take for the fire truck?"

Deputy Director Huang was hoarse and looked at the burning woods with a constipated expression.

The tail flame launched by Xinyuan-2 was too large and violent. The Qiongzhou launch site did not consider such a level of launch. The launch station was a bit close to the noise-absorbing woods.

Fortunately, the fire brigade was on standby at any time during the launch, and they strengthened their strength for this mission. They also had plans for forest fires, and the fire was quickly controlled.

Everyone in the control room naturally saw the forest with thick smoke in the picture, and this unexpected episode diluted the tense atmosphere a little.

At the Xinyuan Launch Site No. 1 recycling station next to the Wenchang Launch Site, the lonely tower is also silently waiting for its own link.

In the air, the first stage of Xinyuan No. 2 had been adjusted to a vertical falling posture and fell rapidly to the ground.

At altitudes of 10,000 meters and 6,000 meters, the engine ignited twice for a short period of time to reduce the speed, and then waited until 4,000 meters to start.

The M220 liquid oxygen methane engine performed stably, and only the central one started. However, it was completely redundant for the rocket body, which already weighed only dozens of tons.

At a distance of 2,000 meters from the ground, the throttle valve increased the thrust, and the crowd on the beach saw the familiar rocket again, but this time the tail flame was much smaller.

In CCTV's tracking camera footage, most of the original panda painting on the surface has been ablated, with only half of the green bamboo left.

The forty-five-meter-high first level is as high as the entire Long March 2F. Such a huge giant is falling little by little, giving people a majestic sense of oppression.

Under the command of the powerful control system, the ground only needs to guide the coordinates, and the No. 1 engine in the center continuously swings the nozzle and floats to the No. 1 recovery station.

The recovery tower is ready, with hydraulically driven steel supports ready to extend.

Due to its huge size, the first-level recovery procedure of Xinyuan-2 is not to aim at the landing point from the air and then fall directly. Instead, it controls the height at a certain distance from the tower, and then slowly approaches the tower diagonally.

The spectators on the beach watched as if they were watching a miracle as they saw the thick and long first-stage rocket slowly slowing down as if it were being turned upside down and getting closer to the 100-meter-high tower.

In the control room, the numbers on the sensors kept beating.

The rocket was less than 30 meters above the ground and less than 20 meters away from the tower. As long as it swayed a little, it would hit and turn into a pile of debris.

However, Xinyuan-2 is heavy enough, and the seven engines at the bottom lower the center of gravity. Unless there is a strong cross wind, it can be corrected on its own.

The first stage, which continued to emit tail flames, was getting closer and closer like a tower. Just when the distant spectators thought they were about to collide with each other, the recovery tower stretched out two slender "arms", which happened to support the rocket on both sides of the top. Two or three meters below the eight grille rudders.

The throttle valve began to slowly reduce the flow rate, and the RCS under the grille rudder desperately sprayed gas in all directions to stabilize the posture until the reinforced grille rudder contacted the steel cantilever beam.

The engine was shut down immediately, and the first stage of Xinyuan 2 was supported by the recovery tower with two steel arm beams and hung on it.

According to the camera on the top of the tower, there is a certain gap between the rocket body and the arm beams on both sides, and the error does not exceed 20%.

Xinyuan 2 was recovered successfully upon its first launch.

In front of the YouTube live broadcast, Ma Yilong tilted his mouth into a twisted O shape.

On the beach, the more than 200,000 spectators seemed to have witnessed a miracle. They were stunned in disbelief and were silent for a moment.

The host in the CCTV studio actually repeated a complete sentence three times. The guests from the space agency had dull expressions and even forgot to read the lines on the teleprompter.

In the launch control room, facing the live broadcast camera and looking at the big screen in front of him, Lin Ju looked calm in front of thousands of netizens. He coolly took off his headphones and slowly began to applaud.

This is the recovery method of starship boosters in the future. The recovery modes of Long March 9 and 10 are also similar. They are both expected to take almost fifteen years from now to be realized, but Xinyuan 2 has done it since its launch.

Even though he had long been confident in the system and system engineers, Lin Ju was still excited and speechless.

In the VIP area of ​​the space agency, He Zhuang had a complicated expression. He compared the scenes of the first recovery of Xinyuan-2 and Long March-6, and his face kept twitching.

Including the staff in the control room, no one expected that such an almost acrobatic recovery method could be successful. It was not until a minute later that they reacted and started clapping, and it became more and more enthusiastic, growing like a tidal wave.

On the beach opposite the launch site, in thousands of schools in Sichuan, and in front of the TV sets in countless families, they are all filled with heartfelt cheers and joy.

Even ordinary people who know nothing about aerospace can intuitively feel the crazy technical power behind Xinyuan 2.

Chen Jun, who was still communicating with the leader on the phone, was also stunned. The other end of the phone immediately learned about the innovation of Xinyuan No. 2, and immediately said that Chen Jun would be fully responsible for making Xinyuan the best domestic brand in China.

Xinyuan-2 created a miracle in the history of spaceflight with the fastest speed and the most powerful technology.

Lin Ju turned around and looked at everyone in the control room, seeing an unprecedented lively scene.

The director of the Launch Administration came directly over and pressed his shoulders firmly:

"Chairman Lin, it seems that the Qiongzhou Launch Site will become the nurturing place for the future space industry. We will organize every Xinyuan launch mission in the most responsible manner!

Congratulations, now the space agency is not as good as Xinyuan Aerospace. "

"Ahem." A cough interrupted his congratulations. The director turned his head impatiently and saw the head of the space agency standing behind him with a sullen face. He hurriedly said hello and walked away thoughtfully.

When the boss walked up to Lin Ju, he had an encouraging smile on his face. Then he looked back at his subordinates as if inadvertently. After a murderous look, he held Lin Ju's hand and said solemnly:

“Xinyuan Aerospace Power has proven that it has sufficient technical capabilities, and you also have the qualifications to enter the national aerospace project. You can actively participate in the space agency’s external bidding in the future;

In addition, I know that some of Xinyuan's projects may involve sensitive technologies. If they have confirmed uses and can accept a certain degree of control, exchanges can be made. "

What the boss means is actually very simple: you are so powerful, come and stand with the space agency, and you will really enter the national system in the future.

There are also sensitive technologies, which obviously refer to the nuclear materials I asked about before. Now it seems that it is not non-negotiable.

This was a complete surprise for Lin Ju. It meant that even if there were no system tasks, he could still push forward with the help of state funds and power.
