After nearly eleven months, Zhang Wei's spacecraft was finally completed. Although the country's Chang'e-7 spacecraft has accelerated its progress, it will take at least four months to complete. The reason why there is such a long time The gap is due to the fact that Zhang Wei spared no expense on the one hand, and on the other hand, it is because the country is building a spaceship industry base and moving all supporting factories to the base. This integration process took a long time.

However, these are not important. The important thing is that Zhang Wei can become the first batch of people in China to land on the moon. This is a great honor.

September 13.

Zhang Wei, Qin Xiaobu, Zhang Zhijian, and Liu Hai came to the spaceship factory. Inside the factory, a 100-meter-long spaceship has been assembled. The four of Zhang Wei watched with excitement.

The interstellar age, it is finally time to take the first step.

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

In the first stage, you can only navigate in the planetary system. Taking the solar system as an example, any planetary voyage between Mercury and Neptune is called a planetary system voyage. For us humans, the lowest planetary system voyage is the earth to Mars.

In the second stage, star system navigation can be realized. The voyage from the solar system to any star in the Milky Way is called the voyage of the star system. The lowest voyage to the star system is the voyage from our solar system to Alpha Centauri. sailing between.

In 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 galactic voyage is from the Milky Way to the Large and Small Magellanic Clouds.

These three stages represent the three levels of human civilization ability.

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

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

"Beidou, start the spacecraft self-inspection program."

After Zhang Wei entered the spaceship, he opened his mouth to give instructions.

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

"Self-test program started."

The sound of Beidou sounded in the spaceship. At the same time, a virtual three-dimensional screen was projected in front of Zhang Wei and the others. On the screen, there was a striking progress bar that was slowly increasing with time.

1……

15...

75...

99...

Looking at the increasing progress bar, the four of Zhang Wei couldn't help being a little excited, and their breathing was a little short.

When the progress bar reads to 100%.

Ding.

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

"Only eight hours."

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

"It is estimated that it will take ninety days to reach Mars."

Beidou responded.

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

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

"Go by yourself, I don't have time to mess around with you,

This is 180 days, a full six months! "

Zhang Wei shook his head and said, "The speed of the spacecraft is still too slow. It will take ninety days to go to Mars. It is like a snail. There is no way. Our current power system is too backward. It seems that I will focus on it in the future. Gradually transferred to the power system of the spacecraft, but I still have a lot of ideas to complete, it is really a headache."

The power system of this spaceship is designed by the country. The engine used is an ion engine. The speed is too slow. Zhang Wei is going to spend some time to develop a nuclear fusion engine. In theory, the speed of a nuclear fusion spacecraft can reach the speed of light. One-tenth of that, that is, 30,000 kilometers per second. Compared with ion engines, this is a qualitative leap. It only takes more than ten seconds to go from the earth to the moon!

However, if you want to sail in the sea of ​​stars, this speed is still not enough. At the speed of light of 10, 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 stop suddenly at 10 light speeds, right? And acceleration also requires a process, so it will take about 60 years to reach Proxima Centauri, and 60 years is enough to raise a generation or two in space!

Therefore, Zhang Wei's research focus will be 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 will be elongated, so it only takes about 3.3 years to reach Proxima Centauri. As for traveling between planets in the solar system, it can be reached in minutes.

However, even an antimatter engine can only allow humans to move within the Milky Way, because the Milky Way is too vast, and even if our travel speed can reach the speed of light, it will take 100,000 years to cross the Milky Way. Therefore, if you want to realize real galaxy navigation, you must rely on the legendary warp drive to achieve super-light flight.

...

Landing on the moon is such an exciting thing, of course, it cannot be done in a low-key manner, it must be high-profile, and let the whole world know. Therefore, Zhang Wei did not immediately order Beidou to fly the spaceship to the moon. He, Liu Hai, Qin Xiaobu, and Zhang Zhijian three After discussing for a while, they made relevant plans and left the spaceship. When leaving the spaceship, Qin Xiaobu was still thinking about going to Mars, but Zhang Wei, Liu Hai, and Zhang Zhijian did not agree. They are the core figures of the future technology company. Tech companies are likely to experience dramatic upheavals. ***book*** (Sikushu)
