Chapter 319

Zhang Heng felt like he was in an unprecedented earthquake. Everything around him was shaking wildly. The swing of those metal parts even made people worry that they would fall apart next moment.

When the rocket leaves the ground, the strong acceleration generated will press the people in the command module firmly on the aluminum seat. It's like a gorilla sitting on your chest. Even the simple action of raising his arm in ordinary days becomes extremely difficult. Fortunately, Zhang Heng has trained in the space center before, and is not familiar with this situation Strange.

The numbers on the main display board are beating wildly!

…… 135 seconds after take-off, central engine off In 150 seconds, the four F1 engines in the periphery were also flamed out, and the fuel in the first stage rocket had been burned out. At this time, Apollo 11 also reached an altitude of 68000 meters.

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

On the other side, the two-stage rocket also began to work. The J2 rocket engine increased the flight speed from 9200 km / h to 24600 km / h, and took the spacecraft into the upper atmosphere.

The whole process lasted for six minutes. After that, the second stage rocket completed its mission and separated. It was the third stage rocket's turn to start the relay ignition. The speed of Apollo 11 continued to climb up. However, compared with the time when it just took off, the vibration was much smaller, although the heavy acceleration still existed.

Until 2.75 minutes after the ignition of the three-stage rocket, the engine was shut down, and the spacecraft successfully entered earth orbit at the speed of 28000 km / h.

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

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

Although in the real world, he has seen many books and movies related to aerospace, witnessed the launch of Shenzhou-5, and had a comprehensive understanding of every step of the moon landing program in Apollo training camp, this moment is really coming. As one of the witnesses, it is really a different feeling.

Now they are living in space 166 kilometers away from the surface of the earth. Their helmets are suspended like feathers at hand. They can see the earth under them through the porthole.

It's hard to describe such a scene in words. A blue planet is moored alone in the velvet dark sky. The arc horizon looms in the blue haze. The clouds float silently on the blue ocean. The whole ground is like a huge palette, full of bright colors, blending with the transition colors, the yellow sand Desert, rugged mountains, dark green rainforest Give people a kind of unspeakable shock and moving.

Even with Zhang Heng's consistent calmness, he was rarely absent-minded at this moment.

At the same time, a series of system prompts came to his ears,

[appreciating the earth in space, the mission has been completed 】

[will return in 4 days 】

[successfully aboard Saturn 5 carrier rocket, game points + 10, you can go to the character panel to view relevant information 】

[successfully enter the earth orbit, game points + 20, you can go to the character panel to view the relevant information 】

[successfully maintain continuous weightlessness for more than 500 seconds, game points + 10, you can go to the character panel to view relevant information 】

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

Collins also unfastened his seat belt, pushed his legs and floated to Zhang Heng's side. "If you see such a scene only once, you will never forget it. Congratulations, David. You are a real astronaut now, but your golden Brooch can't be obtained until you get back to the earth ball."

On the other hand, Armstrong's face also had a rare smile. No matter how many missions this is, it's hard not to immerse himself in seeing the beauty of the earth from this angle.

But now they have other work to do. Apollo 11 will stay in low earth orbit for a period of time and fly around the earth. The spacecraft will make the final inspection here, and then Saturn 5 will ignite again to take them on the official journey to the moon.

This step is also called Earth Moon orbit injection.

So far, although Zhang Heng's mainline mission has been completed and he has gained 50 game points, he is still more than four days away from the date of return. Being in space, he has no choice but to complete the moon landing mission with Armstrong and Collins.

Confirm that everything is in good condition and the direction of the spacecraft is OK. The J2 engine of Saturn 5 ignited again 148 minutes later, and took the spacecraft away from the earth with the last remaining fuel.

The Saturn-5 launch vehicle has also successfully completed all its missions.

And then it's time to test the three men on board.When the whole spacecraft was designed, the lunar module was placed in the protective layer of the rocket. To pull it out, we need to separate the command and service module first.

After that, the astronauts drove the separated command and service module to rotate 180 degrees to complete the U-turn, and then returned to the front of the rocket to dock with the lunar module inside, pull it out, and discard the useless third stage rocket.

Although some of them come from the ground control center, the whole docking process needs manual operation, and any small error in operation may bring disastrous consequences.

"The rest is up to you." Armstrong to the side of Collins road.

The latter nodded and took a deep breath.

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

In order to avoid Collins distraction, Zhang Heng and Armstrong no longer speak in the whole process, but quietly watch the whole docking process through the porthole above their heads.

Collins carefully adjusted the angle and position of the spacecraft by using the thruster, just like he was picking up the diamond with tweezers. His hand holding the control lever was always stable. Finally, with a slight tremor in the bulkhead, the small head at the top of the command and service module was successfully inserted into the docking ring of the rocket, almost exactly.

At this time, three and a half hours after taking off, Apollo 11 officially bid farewell to the earth and flew to the moon 300000 kilometers away.
