Chapter 256

After nearly 11 months, Zhang Wei's spaceship has finally been completed. Although the national chang'e-7 spaceship has accelerated its progress, it will take at least four months to complete. The reason why there is such a big time gap is that Zhang Wei does not hesitate to pay any cost, on the other hand, the country is building a spaceship industrial base and will provide all supporting works The factory moved to the base, which took a long time.

However, none of this matters. What matters is that Zhang Wei can become the first group of people to go to the moon in China, which is a great honor.

September 13.

Zhang Wei and Qin Xiaobu, Zhang Zhijian and Liu Hai came to the spaceship factory. Inside the factory, a 100 meter long spaceship has been assembled. The cold metallic luster and the size of a giant make Zhang Wei's four people see it boiling.

Star age, it's finally the first step.

According to Zhang Wei, the interstellar age can be divided into three stages.

In the first stage, we can only sail in the planetary system. Taking the solar system as an example, any planetary navigation from mercury to Neptune is called planetary navigation. For us, the lowest planetary navigation is from earth to Mars.

In the second stage, the navigation of star system can be realized. The navigation from the solar system to any star in the Milky way is called the navigation of the stellar system. The lowest navigation of the stellar system is the navigation from our solar system to Alpha Centauri. The navigation of the stellar system is also called the interstellar navigation, which refers to the navigation between two stars.

The third stage, from any star in the Milky way to any star outside the Milky way, is called Galaxy navigation. The lowest Galaxy navigation is from the Milky way to the large and Small Magellanic galaxies.

These three stages represent the three levels of human civilization.

Human beings have just entered the first stage of the interstellar age, which is equivalent to not leaving the novice village, but even so, it is a matter of pride.

With excitement, the four Zhang Wei people came to the entrance of the spaceship. The identification system of the population department recognized the identity of the four Zhang Wei people, then opened the entrance, and the four Zhang Wei people entered the spaceship immediately.

"Beidou, start the spaceship self inspection program."

After Zhang Wei entered the spaceship, he asked.

Not only this spaceship, but also every spaceship he built later is controlled by artificial intelligence. These artificial intelligence are copies of Beidou, so Beidou can take over the control authority of the spaceship at any time.

"Self test program started."

At the same time, a virtual three-dimensional screen was projected to Zhang Wei's eyes. There was a striking progress bar on the screen that was gradually increasing with time.

1%……

15%……

75%……

99%……

Looking at the increasing progress bar, Zhang Wei's four people were all a little excited and breathed a little fast.

When the progress bar reads 100%.

Ding.

A pleasant prompt sound starts, the progress bar turns green, and the voice of Beidou also rings, "Congratulations, boss, the spaceship is in perfect condition, it can take off immediately, and it is expected to reach the moon in eight hours."

"Only eight hours."

Qin Xiaobu, hearing the words, asked, "how long will it take to fly to Mars?"

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

Beidou replied.

"Ninety days Doesn't that mean a round trip only takes 180 days? So the distance between the earth and Mars is not too far. It's totally within the range of bearing. "

Qin Xiaobu looked at Zhang Wei, Liu Hai and Zhang Zhijian with some expectation and said, "otherwise, we will go to Mars directly after landing on the moon? In this way, we are the first people on earth to land on Mars. It will be recorded forever. It's a little exciting to think about it. "

"If I want to go to you, I don't have time for you. It's 180 days, six months!"

Zhang Wei shook his head and said, "the speed of the spaceship is still too slow. It takes 90 days to go to Mars, just like a snail. It's impossible. Our current power system is too backward. It seems that I will gradually transfer my energy to the power system of the spaceship in the future, but I still have a lot of ideas to finish. It's a headache."

The power system of this spacecraft is designed by the state. The engine used is the ion engine. The speed is too slow. Zhang Wei is going to spend some time to develop the fusion engine. In theory, the speed of the fusion spacecraft can reach one tenth of the speed of light, which is 30000 km / S. compared with the ion engine, this is a qualitative leap from the earth to The moon only takes ten seconds!

However, if we want to sail in the sea of stars, the speed is still not enough. At the speed of 10% of light, it will take 40 years to reach the nearest star in the solar system without slowing down. But this is not realistic, because we can't brake at the speed of 10% of light, right? And acceleration also needs a process, so it will take about 60 years to reach the neighborhood star, 60 years is enough 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 or even 0.8 times the speed of light. According to general relativity, the time of high-speed inertial coordinate system will be lengthened, so it only takes about 3.3 years to reach the neighbor star. As for the travel between the planets in the solar system, it can arrive in minutes.

However, even the antimatter engine can only let humans move in the galaxy, because the galaxy is so vast that even if we can travel at the speed of light, it will take 100000 years to cross the galaxy. Therefore, if we want to achieve real Galaxy navigation, we must rely on the legendary warp engine to achieve super light speed flight.

……

Landing on the moon is such a windy thing, of course, it can't be carried out in a low-key way. It must be done in a high-key way so that the whole world can know. Therefore, Zhang Wei didn't immediately order Beidou to fly to the moon. He discussed with Liu Hai, Qin Xiaobu and Zhang Zhijian for a while, worked out relevant plans, and left the spacecraft. When he left the spaceship, Qin Xiaobu said he wanted to go to Mars, but Zhang Wei, Liu Hai and Zhang Zhijian didn't agree. They are the key figures of the future technology company. If he left for half a year at once, the future technology company is likely to have great changes. (to be continued. )
