The material reserve warehouse of the Red Heart spacecraft has been installed in the Hercules rocket. At this moment, the Hercules rocket is standing next to the launching tower. The huge arrow body as high as 70 meters pointed straight at the sky, and a heroic aura that pierced the sky continued to emanate from it.

After the old man issued the order, the five astronauts stood at the same time, facing the screen and saluted a standard military salute to all the operators in the control hall, then turned around and left the control hall in an orderly manner.

Through the surveillance screen, Zhao Huasheng saw the five astronauts boarded the shuttle bus, and the shuttle bus drove directly into the launch tower. The five astronauts got out of the car and then rose to a height equal to the tip of the Hercules rocket through the elevator.

Staff have evacuated from the launch tower. Through the air ferry bridge, five astronauts entered the rocket one by one. Then the exit of the material reserve warehouse was closed and the rocket passage was closed.

The cameras in the reserve warehouse transmit the astronauts' pictures in real time, and the space suits in the cabin monitor the astronauts' heart rate, breathing frequency, blood pressure, body temperature and other data at all times.

The windmeter reported the surface wind speed and high altitude wind speed at this moment, and the meteorological satellite reported the weather conditions at this moment. The rocket sensors reported the operation of instruments in various parts of the rocket. The staff were working nervously, and an extremely solemn atmosphere enveloped the entire control hall. The old man's image was always on the big screen, and it was obvious that the old man was watching here.

About 40 minutes after the astronauts entered the rocket, Wang Tang came to the big screen again and reported to the old man: "Report to the head of state, everything is ready, the rocket modules are normal, the weather conditions are good, please instruct!"

The old man nodded: "Start!"

Wang Tang turned around and shouted loudly: "Enter the thirty-second countdown!"

Two huge Arabic numerals appeared on the other screen, one was three and the other was zero. After a moment, the numbers changed and became twenty-nine.

The huge steel frames connected to the launch tower around the rocket suddenly separated at this time, cutting off the connection between the Hercules rocket and the launch tower.

The detection signal reports of various rocket modules are constantly coming out. After these reports, all of them are added with four words "Everything is normal". This means that the Hercules rocket is in good condition.

When the countdown was four, on another large screen that broadcasted the real-time outdoor scene of the Hercules rocket, Zhao Huasheng saw a red flame appearing at the tail of the Hercules rocket. The flame was not strong, but it looked full of power.

The rocket quickly strengthened in just four seconds and eventually turned into a vertical jet. While the flames were strengthening, the four boosters installed on the Hercules rocket were also ignited at the same time. The flames of the boosters and the flames of the main engine of the rocket blended together, and eventually became extremely bright, making people almost unable to see directly.

"zero!"

"Start!" Wang Tang yelled out the word "Start!"

At this moment, the flames ejected from the tail of the Hercules rocket were strengthened again. When these flames just left the rocket, they turned into colorless and transparent. Only when the air around them, which was distorted and deformed due to the high temperature, showed their strength. After a few meters away from the tail of the rocket, they showed a strong red and rolling ball.

A large amount of white thick fog evaporated at the tail of the rocket, almost covering a space of dozens of meters. Zhao Huasheng knew that the flames ejected by the rocket were led out by the diversion trough, and then the liquid used to cool down quickly evaporates.

At this moment, even Zhao Huasheng, who was sitting at least more than 1,000 meters away from the Hercules rocket, felt the earth trembling. It was a very slight, but very dull shaking, like an earthquake, but it was different from an earthquake.

Zhao Huasheng raised his head and saw from the real-time outdoor display screen that the Hercules heavy launch vehicle, which was as high as 70 meters and weighing more than 4,000 tons, slowly taking off. At the beginning, its speed was very slow, like a rope slowly lifting it up, but after just over ten seconds, its speed increased to a height that was somewhat shocking.

With extremely fast acceleration, the gravity inside the rocket can even reach more than ten times the gravity of the earth. This can be seen from the somewhat distorted faces of the five astronauts lying flat in the reserve warehouse.

Under such a huge gravity, the astronauts could not even raise their arms. They could only lie quietly in the reserve warehouse and use all their strength to fight against this huge gravity beyond ordinary people's imagination.

A large number of things that seemed to be fragments were peeled off from the rocket's body, and spilled to the ground like it was raining. Zhao Huasheng knew that those fragments were the insulation layer of the rocket, and they were actually some foam plastic.

When the Rockets were still on the surface, in order to prevent the low temperature on the ground from affecting the material structure of the rocket's body, engineers put these things on the rocket's body shell. When the rocket took off, violent friction with the atmosphere would peel off the plastic foam, which formed the fragments we saw at this moment.

There were constant reports in the control hall. Listening to the "normal" and "normal", Zhao Huasheng's slightly nervous mood calmed down.

More than twenty seconds after the rocket took off, the rocket's ascending direction changed. It no longer pointed vertically at the sky, but began to shift to the east slightly. Because the earth's rotation is from west to east, shifting to the east can increase its speed by using the earth's rotation.

More than a minute later, the four boosters installed on the Hercules rocket body left the rocket at the same time. They had fulfilled their responsibilities, so it was time to leave. At this moment, the speed of the rocket could not reach the first cosmic speed of the earth, so the lifting boosters would land on the earth at an extremely high speed and then be damaged in violent friction with the atmosphere. If the combustion is not sufficient, it is possible that some wreckage will fall to the ground.

After the booster is separated, it is soon time for the first-stage engine to separate. In order to ensure strong driving force, the Hercules rocket has a total of three-stage structures. Among these three-stage structures, the first-stage engine is responsible for the most important and arduous tasks. Therefore, it is also the largest in size. The total length of the Hercules rocket is 70 meters, and the length of the first-stage engine reaches nearly thirty meters.

The Hercules rocket was still flying at high speed, but at this moment the flame at its tail suddenly disappeared. The next moment, the first-stage engine, which was thirty meters long, left the rocket with a bang. It also landed on the earth like a booster separated before, and then disappeared in the violent friction with the atmosphere.

The primary engine is disengaged and the secondary engine is ignited, and it will take on the heavy responsibility of continuing to send the rocket into orbit.

The second-stage engine ignition work for less than a minute and then followed the footsteps of the first-stage engine. It also fell off the rocket and fell into the atmosphere, and the third-stage engine began to ignite.

At this moment, the Hercules rocket is more than 300 kilometers away from the surface and has reached the height of the low earth orbit. But this height is not enough, and it will continue to rise.

The air here is extremely thin, so the fairing at the tip of the rocket is useless. It is also thrown away by the rocket and falls into the atmosphere.

The material reserve warehouse is completely exposed to the space environment. However, there is also a complete life maintenance system in the material reserve warehouse, so this will not have any impact on the astronauts in the warehouse.

The third-stage engine also completed the mission after working for more than half a minute. However, it will not be thrown away from the Rockets. At this time, the material reserve warehouse is to leave the Rockets.

This step is the separation of the ship and arrows. After the acceleration of the third-stage rocket engine, the material reserve warehouse has reached enough speed and can enter the orbit of the earth. In the future, it will travel alone.

The launch was basically successful. In the control hall, the staff also recovered from the nervous mood. The display screen was still broadcasting real-time images of the astronauts. Zhao Huasheng saw that the astronauts had been free from the trouble of huge gravity. At this moment, they were in a weightless environment. Zhao Huasheng saw them floating spontaneously in the cabin, as if in the water.

"Since there was no accident." Zhao Huasheng breathed a sigh of relief and threw out the unknown premonition in his mind.

The material reserve warehouse also has its own propulsion engines, which will be used to adjust the orbit and speed of the cabin. In the next time, the material reserve warehouse will circulate the earth at a speed of 87 minutes per lap for two weeks, and adjust its posture, angle and speed during this time, and finally dock with the Red Heart rocket.

Zhao Huasheng has been waiting here. In the material reserve warehouse, the sun rose and set, rose and set, and it took two steps in total. The figure of the Red Heart sun detection spacecraft finally appeared in sight.

The speed of the Material Reserve Warehouse and the Red Heart spacecraft are at 9:3 kilometers per second at this moment. This is an incredible high speed, but because both maintain the same speed, they look like they are still. In such a near-static situation, the two are slowly approaching each other. Finally, with the assistance of the ground staff, the interface is smoothly connected, and the steel claws used to fix the docking of the two are also smoothly extended, firmly connecting the two.
