v2 Chapter 64： mission completed

Zhang Heng felt like he was in an unprecedented earthquake, everything around him was shaking in a crazy way, and the amplitude of those metal parts even made them worry that they would fall apart in the next moment.

When the rocket left the ground, the strong acceleration caused the person in the command cabin to be firmly pressed on the aluminum seat, and it felt like a gorilla was sitting on your chest, even on weekdays. The simple movements of raising arms have become extremely difficult, but fortunately, Zhang Heng has already been trained in the space center before, and this situation is no stranger.

The numbers on the main display are beating wildly!

... 135 seconds after take-off, the central engine was shut down ... 150 seconds, the four F1 engines on the periphery were also extinguished, and the fuel in the first stage rocket had been burned out. At this time, Apollo 11 also came to six. Above eight thousand kilometers.

The explosive device blasted the first stage rocket and the interstage ring. The former detached from the launch escape system at the top of the spacecraft and crashed into the deep sea after the speed ran out.

The second-stage rocket on the other side also began to work. The J2 rocket engine increased the flight speed from the previous 9200 kilometers per hour to the horrible 24600 kilometers per hour, and took the spacecraft into the upper layer of the atmosphere in one fell swoop.

The entire process lasted a full six minutes. After that, the second-stage rocket that completed the mission was also separated. It was the third-stage rocket to start the relay ignition. The speed of the Apollo 11 continued to rise, but this time and just took off Compared with the time, the vibration has been much smaller, although heavy acceleration still exists.

Until the third-stage rocket fired 2.75 minutes, the engine was turned off, and the spacecraft successfully entered Earth orbit at a speed of 28,000 kilometers per hour.

At this moment, the ground control center in Houston was jubilant because it meant that the launch phase was successfully completed.

After the main engine was turned off, the thrust dropped to 0 in just half a second, and Zhang Heng's chest pressure suddenly disappeared and switched to the free-fall state, but the seat belt still kept him firmly fixed on On the seat.

Although in the real world, he has seen many books and movies related to spaceflight, and has witnessed the launch of Shenzhou-5. At the same time, he also fully understood each step of the moon landing plan in the Apollo training camp. However, But this moment really came. Being in it, as one of the witnesses, this is indeed a completely different feeling.

They are now in a space 166 kilometers from the surface of the earth. The removed helmets are suspended like feathers on their hands, and the earth beneath them can be seen through the porthole.

It is difficult to describe such a scene in words. A blue planet is solitary moored in the velvet-like dark space. The curved horizon is looming in the blue atmospheric mist. Clouds drift silently on the blue ocean. The entire ground is like a huge palette, painted with bright colors, blending with the transition colors, those yellow deserts, undulating mountains, dark green rain forests ... give an indescribable shock and Moving.

Even with Zhang Heng's consistent calmness, it is rare to be a little lost at this moment.

At the same time, a series of system prompts came from his ear.

[Appreciation of the earth in space, the mission has been completed ...]

[Will return in 4 days ...]

[Successfully boarded the Saturn 5 carrier rocket, the game points +10, you can go to the character panel to view related information ...]

[Successfully entered the Earth's orbit, the game points +20, you can go to the character panel to view related information ...]

[Successfully maintain a continuous weightlessness state for more than 500 seconds, game points +10, you can go to the character panel to view related information ...]

"It's beautiful, isn't it?"

Collins also unfastened his seat belt, kicked his legs, and floated to Zhang Heng's side. "As long as I see this scene once, I can't forget it in my life. Congratulations, David, you are now a real Astronaut, but your golden brooch will not be available until you return to Earth. "

On the other side, a strong smile also appeared on Armstrong's face. No matter how many times this was his mission, it was hard not to be immersed in seeing the beauty of the earth from this angle.

But now they have other work at hand. Apollo 11 will berth in low-Earth orbit for a while, and make a circle around the ground. The spacecraft will make a final inspection here, and then Saturn 5 will reignite. , Take them formally on their journey to the moon.

This step is also called the Earth-Moon orbit injection.

At this point, although Zhang Heng's main mission has been completed and he has received 50 game points, he is still more than four days away from the date of return. In space, he has not completed the moon landing mission with Armstrong and Collins. Other options.

Make sure that everything is in good condition, and that the direction of the spacecraft is no problem ~ www.novelhall.com ~ The J2 engine of Saturn 5 re-ignited after 148 minutes, leaving the spacecraft completely out of the earth with the last remaining fuel.

The Saturn 5 carrier rocket also successfully completed all its missions.

Then it was time to test the three men on the ship.

When the entire spacecraft was designed, the lunar module was placed in the protective layer of the rocket. To pull it out, the command / service module needs to be separated first.

Afterwards, the astronaut drove the separated command / service module to rotate 180 degrees, completed a U-turn, returned to the rocket, docked with the lunar module inside, dragged it out, and discarded the third-stage rocket that had no effect.

Although some of this comes from the help of the ground control center, the entire docking process requires manual operation, and any small mistakes in operation may bring catastrophic consequences.

"I'll leave it to you," Armstrong said to Collins aside.

The latter nodded and took a deep breath.

He maneuvered the command / service capsule and the rocket successfully, completed a rollover 300 meters away, and then re-approached Saturn 5 at a relative speed of 2 meters per second.

In order to avoid the distraction of Collins, Zhang Heng and Armstrong stopped talking during the whole process, but just watched the entire docking process quietly through the porthole overhead.

Corinth used the thruster to carefully adjust the angle and position of the spacecraft, just as carefully as holding a diamond with tweezers. His hand holding the joystick was always stable, and eventually, with a tremor of the bulkhead, the command / The small head at the top of the service cabin was successfully inserted into the docking ring on the rocket, almost exactly the same.

At this time three and a half hours have passed since the takeoff, Apollo 11 officially said goodbye to the earth and flew to the moon 300,000 kilometers away.
