Zhang Heng feels like he is in an unprecedented earthquake. Everything around him is shaking wildly. The swing of those metal parts even makes people worry that their next moment will fall apart.

When the rocket left the ground, the strong acceleration generated firmly pressed the person in the command cabin against the aluminum alloy seat. It felt like a gorilla was sitting on your chest, even normal. The simple movement of raising the arm has become extremely difficult, but fortunately, Zhang Heng has already been trained in the space center before, and he is no stranger to such a situation.

The numbers on the main display board are beating wildly!

… 135 seconds after take-off, the central engine is turned off … 150 seconds, the four peripheral F4 engines are also turned off, the fuel in the first stage of the rocket has been burned out, and then Apollo 1 has reached 60000 Above 8000 meters.

The explosive device exploded the first stage rocket and the interstage ring. The former broke away with the launch escape system at the top of the spaceship, and fell into the deep sea after the speed was exhausted.

On the other side, the Level 2 rocket also began to work. The J2 rocket engine increased the flight speed from the previous 92001000 meters each hour to the terrible 246001000 meters each hour, and rushed into the upper atmosphere with spaceship in one fell swoop.

The entire process lasted for a full 60% of the time. After that, the Level 2 rocket that completed the mission also completed separation. It was the turn of the Level 3 rocket to start the relay ignition. The speed of Apollo 1 continued to climb upwards. Compared to take-off, the vibration is much smaller, although heavy acceleration still exists.

Until the Level 3 rocket fired for 2.75 minutes, the engine was turned off, and the spaceship successfully entered Earth orbit at a speed of 280001000 meters each hour.

At this moment, the ground control center in Houston was full of joy, because it meant that the launch phase of Perfection was completed.

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

Although he has seen a lot of books and movies related to aerospace in the Real World, he has also witnessed the launch of Divine Boat 5 with his own eyes, and at the Apollo training camp he also fully understood each step of the moon landing plan However, this moment really came, surrounded by this, as one of the experiencers, this is indeed a completely different feeling.

Now they are in the space of 1661000 meters from the surface of Earth. The removed helmet is suspended on the hand like a feather, and Earth can be seen through the porthole.

It is difficult to describe such a scene with words. A blue planet is solitary in the deep velvet sky, the curved horizon is faintly discernible in the blue atmospheric mist, and the clouds float silently on the blue ocean , The whole ground is like a huge palette, painted with bright colors, blending with the transitional colors and water, those yellow deserts, rolling mountain ranges, dark green rainforests … gives an unspeakable expression Shocked and moved.

Even with Zhang Heng’s usual calmness, somewhat absent-minded is rare at this moment.

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

[Appreciate Earth in space, the mission has been completed …]

[Will return in 4 days …]

[Successful ride on Saturn 5 carrier rocket, game points +10, you can go to the character panel to view related information …]

[Successfully entered the Earth track, game points +20, you can go to the character panel to view related information …]

[Successful maintenance of continuous weightlessness for more than 500 seconds, game points +10, you can go to the character panel to view related information …]

“Is it beautiful?”

Collins also unfastened his seat belt, kicked with two legs, and floated to Zhang Heng ’s side Astronauts, but your golden brooch wo n’t be available until you return to Earth. “

On the other side, Armstrong’s face also had a rare smile. No matter how many times this was his first mission, it was difficult to witness the beauty of Earth from this angle.

But now they have other work to do at their disposal. Apollo 5 will be parked in low-Earth orbit for a period of time, orbiting the ground. Spaceship will conduct a final check here, and then Saturn 1 will ignite again. , Take them on a formal trip to the moon.

This step is also known as earth-moon orbit injection.

At this point, although Zhang Heng’s main line mission has been completed, he has earned 50 game points, but he is still more than 4 days away from the return date. He is in space, and he has not completed the mission to the moon with Armstrong and Collins. Other options.

Confirm that everything is in good condition and there is no problem with the direction of the spaceship. The Saturn 5 J2 engine is ignited again after 148 minutes, and the spaceship is completely separated from Earth with the last remaining fuel.

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

And then it was time to test 3 people on the spaceship.

When the entire spacecraft was designed, the lunar module was placed in the protective layer of the rocket. To pull it out, you need to separate the command service module first.

Afterwards, the astronauts drove the separated command service cabin 180 degrees, completed the U-turn, and returned to the front of the rocket, docking with the lunar module inside, dragging it out, and discarding the Level 3 rocket that had no effect.

Although there is also a part of the help from the ground control center, the entire docking process requires manual operation, and any minor mistakes in operation may have catastrophic consequences.

“The next part is for you.” Armstrong said to Collins aside.

The latter is nodded, taking a deep breath.

He managed to separate the command service module from the rocket, completed the flip at a distance of 300 meters, and then approached Saturn 2 at a relative speed of 5 meters per second.

In order to avoid the distraction of Corinth, Zhang Heng and Armstrong stopped talking during the whole process, and just quietly watched the whole docking process through the porthole above the head.

Collins used the propeller to cautiously adjust the angle and position of the spaceship, just as carefully as holding the diamond with tweezers. His hand holding the joystick was always stable. Eventually, with a flutter of the bulkhead, he commanded the service The small head at the top of the cabin successfully inserted into the docking ring on the rocket, almost exactly.

At this time, three and a half hours have passed since the take-off. Apollo 3 officially bid farewell to Earth and flew to the moon 300,000 kilometers away.
