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

In order to complete the system's mission and expand the impact of aerospace as much as possible, Lin Ju spent a lot of extra money and energy.

In addition to finding a way to get the space agency to contact CCTV for live broadcast, they also asked the Sichuan Department of Education.

Nowadays, most schools in Sichuan are equipped with ancient CRT TVs. The launch day is Tuesday, so why not leave the students to watch the rocket launch.

So most high schools and junior high schools with evening self-study received instructions: Tonight at 18:00, the TV will be turned on.

As for places other than Shuchuan, Lin Ju doesn't have that ability yet. He won't know if he has a chance until he sends people there.

On the other side of the ocean, in addition to Lao Ma, there was also a wealthy rocket man squatting in front of the screen and watching Xinyuan 2.

Jeff Bezos, CEO of Amazon, the world's largest e-commerce website, founded the aerospace company Blue Origin in 2000.

In 2012, Blue Origin proposed the "New Glenn" rocket plan, which will use seven BE4 liquid oxygen methane engines with a thrust of 250 tons. A single stage can send a 45-ton payload into low-Earth orbit.

However, until now, the BE4 engine has not had a successful test run.

But when he saw New Yuan 2 being erected, and comparing it to the New Glenn rocket that was highly similar to his own PPT, Bezos always felt like he was being NTRed.

Looking at the screen again, it was already 15:00 Beijing time, and there were still 3 hours before launch.

It was very hot on the viewing beach at this time, but in order to occupy the best position, and with more than 200,000 locals gathering together, there was a great risk of heatstroke.

However, what is surprising is that in addition to the patrolling police cars, a line of light trucks drove up on the beach, with people wearing panda-decorated hats standing on top of them distributing mineral water and fans.

They gave everyone in front of them a bottle of mineral water, and those who didn’t have a hat were given a Tianfu-style tourist hat with panda ears. At the same time, they never forgot to say:

"Come to Tianfu to see pandas when you have time."

"Sichuan River has both scenic spots and high technology. If you want to see the rocket, go to the Beach Attraction Management Office to get Jiuzhaigou group travel package coupons!"

"Qiongzhou is too hot, but our Sichuan River is cooler. Red Plains is a summer resort in July and August."

"..."

In order to maximize the value of its 10 million painting, the Tourism and Culture Bureau has made sufficient plans to target those who can afford to fly to Qiongzhou and can afford to fly to Sichuan, and continuously promote the three major specialties of Sichuan: pandas, scenic spots, Rocket.

If Lin Ju hadn't been firm, maybe the Progress would have turned into a Panda...

"Left to launch: three hours."

Although the rocket is now ready for launch, the staff in the launch tower are still sweating from work.

After all, it was a heavy rocket weighing 1,300 tons. The Long March 5 and Long March 2F combined had only this mass. After the explosion, the No. 1 station would be scrapped.

Deputy Director Huang of the Launch Administration set up an altar of incense outside the launch station, worshiped the local indigenous gods, Buddha, Jesus and his brother Hong Xiuquan, the Jade Emperor, von Braun, and Mr. Qian, and prayed for the new moon No. 2 must not explode.

At the Haidian Astronaut Training Center, Zhou Rui and Zhao Xiaowen looked at Xinyuan-2, which was more than 70 meters high. When they thought that the Progress would be installed at the top of the spacecraft at a height of nearly 90 meters, their legs suddenly trembled.

Deng Lei, on the other hand, was full of excitement. He took a deep breath and clenched his fists, looking forward to the moment when he would sit on it and go to heaven.

CCAV:

Host: "There is only one hour left before the launch. Through the reporter's picture, we can see that the Xinyuan-2 Yaoyi rocket is almost as high as the launch tower. How can such a high rocket ensure that it stands firmly and does not sway? ?”

Xinyuan engineer: "...(not wanting to speak, looking at the guests from the space agency)"

Guest from the Space Administration: "Our launch station uses a different method from Aramco..."

"Countdown to fifteen minutes."

At 17:45 in the evening, the setting sun turned into a huge fiery red circle, hanging above the sea level, almost at the same height as Xianyuan 2.

The coconut trees on the seaside cast long shadows in the setting sun, and the bright lights from the launch tower shone on the Xinyuan-2 rocket body, revealing a smiling panda.

At this time, Xinyuan 2 chief engineer Guo Shen, deputy chief engineer Androv and people from the space agency stood in front of the console and looked at the screen seriously.

"Countdown, one minute."

The engine is powered on again for self-test, and the control system checks the status of the ignition system.

On the beach, more than 200,000 people were counting down together.

"Fifteen, fourteen...four, three, two, one!!!"

As the last countdown sounded, two of the seven engines on the diagonal outer ring first emitted white smoke.

The seven engines at the bottom ignite the outer ring first and then the middle. The outer ring is ignited in sequence 2-2-2-1 relative to the two engines starting at the same time.

The shower head in the launch tower began to spray water mist to cool the high-temperature gas around the engine.

In the water mist and escaping oxygen, the engine thrust gradually increased, and the fiery red flames poured out of the diversion trough impatiently.

Different from the Xinyuan-1 modification, under ten times the thrust, the camera on the beach first saw the air around the rocket being distorted by the heat wave, and it took a few seconds to feel the strong vibrations on the ground and air.

This is still a few kilometers apart, and there is a sea in the middle!

In the few seconds just after it left the ground, the orange-red flames of Xinyuan 2 combined with the setting sun looked like two suns, one big and one small.

At this time, according to sensor detection, the total thrust output by the rocket's first stage was as high as 1,550 tons. As the fuel decreased and the thrust increased, the rocket's ascending speed gradually accelerated.

Outside the launch tower, Deputy Director Huang looked at the stable Xinyuan-2 and breathed a sigh of relief.

There were already many clouds around the launch site at this time. They scattered the light of the rocket tail flame to the ground and spread it on every raised face.

At this time, the strong air flow from the rocket finally crossed the water and turned into a strong wind, blowing the ocean water vapor on the faces of the tourists on the beach. However, within a few seconds, the coolness of the water vapor turned into warm water. Air waves.

In the launch control room, the remaining amount of core first-stage fuel was constantly decreasing, and the rocket was getting faster and faster. At this time, it had become the brightest star in the sky.

From the sea to high altitude, the place where the rocket flew produced a track composed of gaps in the clouds, which looked like a ladder to the sky under the illumination of the tail flame at the top.

In the CCAV reporter's picture, the female reporter shouted with all her strength, but her voice was still covered by the cheers of the crowd and the rumble of the Xinyuan 2 engine. In the end, the picture could only be cut to the ground tracking camera, looking at the bottom of Xinyuan 2. Seven engines spitting out light blue flames.

In the space agency's observation area, they had begun to applaud slightly.

Even if such a heavy rocket cannot be recovered, as long as it can be put into orbit, it is an amazing achievement. It is basically the highest pursuit of the space agency in the next ten years.

The first-stage rocket pushed the entire rocket through the atmosphere, and the perspective was cut to the camera at the tail of the second stage. As the first and second stages separated, a gentle white light from the atmosphere appeared in the picture. Then the vacuum version of the hydrogen and oxygen engine in the center of the second stage started, silently ejecting several Nearly transparent tail flame.

The second-stage rocket will put the simulated payload into low-Earth orbit and then turn around and return to the atmosphere. Its mission is only to test the hydrogen-oxygen engine. It will be burned by the violent friction of the atmosphere.

In the secondary camera, the first-stage rocket shut down and began to move away from the secondary as if lying down.

The first stage will use inertia to rise to an altitude of about 160 kilometers, and then adjust its attitude and start descending.
