After nearly 11 months, Zhang Wei's spacecraft was finally completed, and although the country's Chang'e-7 spacecraft has accelerated its progress, it will take at least four months to complete. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

However, none of this is important, the important thing is that Zhang Wei can become the first person to go to the moon in China, which is a great honor.

September 13th.

Zhang Wei, Qin Xiaobu, Zhang Zhijian, and Liu Hai came to the spaceship factory, and inside the factory, a 100-meter-long spaceship had been assembled.

The interstellar era, it's finally time to take the first step.

In Zhang Wei's view, the interstellar era can be divided into three stages.

The first stage is only possible to sail in the planetary system. In the case of the solar system, any planetary voyage between Mercury and Neptune is called a planetary system voyage, and for us humans, the lowest planetary voyage is Earth to Mars.

The second stage is to be able to achieve stellar system navigation. The voyage from the solar system to any star within the Milky Way is called a stellar voyage, and the lowest stellar voyage is the voyage of our solar system to the star A Centauri, and the stellar voyage is also commonly known as interstellar voyage, which refers to the voyage between two stars.

The third stage, the voyage from any star in the Milky Way to any star outside the Milky Way, is called galaxy voyage, and the lowest galaxy voyage is the Milky Way to the Great McGellanic Galaxy.

These three stages represent the three levels of human civilizational capabilities.

Humanity has just entered the first stage of the interstellar era, which is equivalent to not yet leaving the novice village, but even so, it is something to be proud of.

With excitement, Zhang Wei and the four walked to the entrance of the spaceship, and the identification system of the population department recognized the identities of Zhang Wei and the four of them, and then opened the entrance, and Zhang Wei and the four of them immediately entered the spaceship.

"Beidou, start the spacecraft self-test procedure. ”

After Zhang Wei entered the spaceship, he opened his mouth and commanded.

Not only this spaceship, but every spaceship he builds in the future is controlled by artificial intelligence, and these artificial intelligences are all replicas of Beidou, so Beidou can take over the control of the spaceship at any time.

"The self-test procedure is initiated. ”

Beidou's voice sounded in the spaceship, and at the same time, a virtual three-dimensional screen was projected~ In front of Zhang Wei's eyes, there was a striking progress bar on the screen that was slowly increasing over time.

1%……

15%……

75%……

99%……

Zhang Wei and the four of them looked at the increasing progress bar, and they couldn't help but be a little excited, and their breathing was a little short.

When the progress bar is read to 100%.

Bite.

A pleasant prompt sounded, the progress bar turned green, and Beidou's voice sounded, "Congratulations, boss, the spacecraft is in perfect condition, it can take off immediately, and it is expected to reach the moon in eight hours." ”

"It only takes eight hours. ”

Qin Xiaobu's eyes lit up when he heard this, and he asked, "If you fly to Mars, how long will it take?"

"It's expected to take 90 days to get to Mars. ”

Beidou responded.

"Ninety days...... Doesn't that mean that it only takes 180 days to make a round trip, so the distance from Earth to Mars is not too far, and it is completely within the range of bearability. ”

Qin Xiaobu looked at Zhang Wei, Liu Hai and Zhang Zhijian with some expectation, and said, "Why don't we go to Mars directly after we land on the moon?" In this way, we will be the first people on earth to land on Mars, and we will go down in history forever, and I am a little excited to think about it." ”

"If you want to go by yourself, I don't have time to toss around with you, it's 180 days, a full six months!"

Zhang Wei shook his head and said, "The speed of the spacecraft is still too slow, it takes ninety days to go to Mars, it's like a snail, this can't be helped, our current power system is too backward, it seems that I will gradually transfer my energy to the spacecraft's power system in the future, but I still have a lot of ideas to finish, it's a real headache." ”

The power system of this spacecraft is designed by the state, the engine used is an ion engine, the speed is too slow, Zhang Wei is ready to take some time to develop the nuclear fusion engine, theoretically speaking, the speed of the nuclear fusion spacecraft can reach one-tenth of the speed of light, that is, 30,000 kilometers per second, compared with the ion engine, this is a qualitative leap, from the earth to the moon only takes more than ten seconds!

However, if you want to sail in the sea of stars, this speed is still not enough, at 10% of the speed of light, without slowing down, it will take 40 years to reach the nearest star to the solar system - Proxima Centauri, but this is unrealistic, because we can't brake at 10% of the speed of light, right? And acceleration also requires a process, so it will take about 60 years to reach Proxima Centauri, and 60 years is enough time to raise one or two generations in space!

Therefore, Zhang Wei's research will focus on the antimatter engine. If successful, a spacecraft powered by an antimatter engine could theoretically accelerate to 0.5 times the speed of light, or even 0.8 times the speed of light. According to the general theory of relativity, the time of the high-speed inertial coordinate system is extended, so it only takes about 3.3 years to reach Proxima Centauri. As for traveling between the planets in the solar system, it can be reached in minutes.

However, even the antimatter engine can only allow humans to move within the Milky Way, because the Milky Way is so vast that even if we could travel at the speed of light, it would take 100,000 years to travel through the Milky Way. Therefore, if you want to achieve true galactic navigation, you must rely on the legendary warp speed engine to achieve faster-than-light flight.

……

Of course, the moon landing cannot be carried out in a low-key manner, it must be high-profile, so that the whole world knows, therefore, Zhang Wei did not immediately order Beidou to fly to the moon in a spaceship, he discussed with Liu Hai, Qin Xiaobu, and Zhang Zhijian for a while, formulated relevant plans, and left the spaceship. When leaving the spacecraft, Qin Xiaobu still wanted to go to Mars, but Zhang Wei, Liu Hai and Zhang Zhijian did not agree, they are the core figures of the future technology company, if they leave for half a year at once, the future technology company is likely to have huge changes.
