Zhang Heng felt like he was in the middle of an unprecedented earthquake, everything around him was shaking wildly, and the magnitude of the swaying of those metal parts even made people worry that they would fall apart in the next moment.

When the rocket leaves the ground, the powerful acceleration generated will firmly press the people in the command cabin on the aluminum alloy seat, the feeling is like a gorilla sitting on your chest, and even the simple action of raising your arm on weekdays has become extremely difficult, but fortunately, Zhang Heng has carried out relevant training in the space center before, and he is no stranger to this situation.

The numbers on the main display board are beating wildly!

…… After takeoff, the central engine turns off...... In 150 seconds, the four F1 engines on the periphery also shut down, and the fuel in the first stage of the rocket had been burned out, and at this time, Apollo 11 was also at an altitude of 68,000 meters.

The explosive device blew the first-stage rocket apart from the interstage ring and the former, which detached from the launch-and-escape system at the top of the spacecraft and crashed into the deep ocean after running out of speed.

On the other side, the second-stage rocket also began to work, and the J2 rocket engine increased the flight speed from the previous 9,200 kilometers per hour to a terrifying 24,600 kilometers per hour, and rushed the spacecraft into the upper layers of the atmosphere in one fell swoop.

The whole process lasted a full six minutes, after which the second stage rocket that completed the mission also completed the separation, and it was the turn of the third stage rocket to start the relay ignition, and the speed of Apollo 11 continued to climb upward, but at this time compared to when it first took off, the shock was much smaller, although the heavy acceleration still existed.

It was not until 2.75 minutes after the ignition of the three-stage rocket that the engine was turned off and the spacecraft successfully entered Earth orbit at a speed of 28,000 kilometers per hour.

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

With the main engine turned off, the thrust dropped to 0 in just half a second, and the weight on Zhang Heng's chest suddenly disappeared, switching to a state of free fall, but the seat belt on his body still firmly fixed him to the seat.

Although he has seen a lot of books and movies related to aerospace in the real world, and has witnessed the launch of Shenzhou 5, and at the same time he has a comprehensive understanding of every step of the moon landing program in the Apollo training camp, but this moment has really come, and being in it, as one of the witnesses, this is indeed a completely different feeling.

Now they are in space 166 kilometers above the surface of the earth, and their helmets are suspended like feathers, and they can see the earth below them through the porthole.

It's hard to put into words a scene like this, a blue planet moored alone in the velvety darkness of the deep sky, the curved horizon looming in the blue atmospheric mist, the clouds drifting silently over the blue ocean, and the whole ground is like a huge palette, painted with bright colors, blending with the transitional colors, those yellow deserts, rolling mountains, dark green rainforests...... It gives people an indescribable shock and touch.

Even with Zhang Heng's usual calmness, he was rarely a little distracted at this moment.

At the same time, a series of system prompts rang in his ears

[Admire the Earth in space, the mission has been completed......]

[Will return in 4 days......]

[Successfully ride the Saturn 5 launch vehicle, game points +10, you can go to the character panel to view the relevant information......]

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

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

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

Collins also unbuckled the seat belt on his body, kicked his legs, and floated to Zhang Heng's side, "As long as you see this scene once, you can't forget it for the rest of your 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, Armstrong also had a rare smile on his face, no matter how many missions he had made, it was hard not to immerse himself in witnessing the beauty of the earth from this angle.

But now they have other work on their hands, Apollo 11 will be in low-Earth orbit for a while, do a flight around the Earth, the spacecraft will do the final inspection here, and then Saturn 5 will fire again and take them on a formal journey to the moon.

This step is also known as Earth-Moon orbital injection.

At this point, although Zhang Heng's main quest has been completed and he has gained 50 game points, there are still more than four days before the return date, and he has no other choice but to complete the moon landing mission with Armstrong and Collins in space.

After confirming that everything was in good condition and that there was no problem with the direction of the spacecraft, the Saturn 5's J2 engine ignited again after 148 minutes, and the ship was completely removed from Earth with the last remaining fuel.

The Saturn 5 launch vehicle also successfully completed all its tasks.

And then it was time to test the three people on the ship.

The entire spacecraft was designed to be placed in the protective layer of the rocket, and to tow it out, it was necessary to separate the command/service module.

The astronauts then rotated 180 degrees in the detached command/service module to make a U-turn, and then returned to the rocket, docked with the lunar module inside, and dragged it out, while discarding the non-functional third-stage rocket.

Although some of this comes from the help of the ground control center, the entire docking process needs to be operated manually, and any small mistake in operation can lead to catastrophic consequences.

"I'll leave the rest to you." Armstrong said to Collins on the side.

The latter nodded and took a deep breath.

He maneuvered the command/service module and the rocket to successfully separate, flipped 300 meters away, and then reapproached Saturn 5 at a relative speed of 2 meters per second.

In order to avoid Collins being distracted, Zhang Heng and Armstrong stopped speaking during the whole process, and just quietly watched the entire docking process through the porthole overhead.

Collins carefully adjusted the angle and position of the ship with his thrusters, as carefully as if he were picking up a diamond with tweezers, and his hand holding the joystick remained steady, and finally, with a slight tremor of the bulkhead, the small head at the top of the command/service module successfully inserted into the docking ring on the rocket, almost exactly the same.

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

This quest is nearing its end, and it's finally coming to an end............ ┭┮_┭┮, it's too hardcore, I'm even about to become a space enthusiast.
