"Fire!" Following Wang Wei's lifelong command, the main gun of the Ziweixing 1 scientific research expedition ship once again sprayed out the flames of liquid medicine after more than two months.

"Boom!..." 10 shells were fired in a row, flying towards the distant starry sky with the boiling fire of the Ziweixing 1 spacecraft.

At the same time, as the main gun of the spacecraft fired, the speed of the rapidly advancing Ziweixing 1 spacecraft also slowed down at a speed visible to the naked eye in the dazzling light of the fire.

The shells ejected from the main gun, due to the influence of the new gunpowder and the speed of the spacecraft itself during launch, the shells were gone and flew towards the target at a speed of nearly a thousand kilometers.

When the cannonballs were fired, the speed of the spacecraft they were riding on had slowed down to about 17 kilometers per second. This speed was like a snail crawling in the vast solar system. However, Wang Wei did not

Without any order, the spacecraft immediately accelerated and continued to fly forward at this speed.

At the same time, he also ordered the spacecraft's fire controller and radar operators to continue to pay attention to the movements of meteorites.

Although it is not a big problem to hit a large meteorite 500,000 kilometers away in space with humankind's current technology, Wang Wei and the others are not yet sure whether this large meteorite is within their reach.

was shattered in several attacks.

At the same time, even if they smash the meteorite, they must always be alert to the threat of meteorite fragments to them.

However, at this moment, the scientific researcher who was responsible for calculating the data said to everyone with some embarrassment: "Captain Wang! When we calculated the data just now, we made some mistakes, that is, the propagation of light in the universe

, it also takes time. The previous meteorite was 500,000 kilometers away from us, and the position of the meteorite we detected was actually two seconds ago. In other words, the shell we just launched was very

Might not hit that meteorite."

"..." After he finished speaking, everyone in the spacecraft turned to look at him, and everyone was speechless for a while.

"Don't worry, everyone. Due to the rear seat of the main gun of the spacecraft, the speed of our spacecraft dropped from 50 kilometers per second to about 17 kilometers per second, so it is impossible for us to fight with that rocket now.

The meteorite collided, and the meteorite had already passed by before we reached the previous position." Your person who calculated the data spoke again.

"Okay! If you win, you are the boss..." For a moment, people in the spacecraft complained one after another.

"..."

"Okay, everyone, stop arguing! Turn on the engine at the airport and continue to accelerate to 50 kilometers per second. At the same time, everyone, you already understand the situation just now.

Based on this situation, we can boldly guess that the asteroid belt in the solar system is actually much more dangerous than we guessed. After all, we are still so far away from the asteroid belt, but even at such a long distance, we

We can still encounter large asteroids on our voyage, which means that the number of meteorites in the asteroid belt is much more than we imagined."

Since there is still a distance of nearly 1.3 astronomical units between the asteroid belt and Mars, that is to say, a distance of nearly 200 million kilometers, even if the Ziweixing 1 spacecraft they are currently traveling on is traveling at its fastest speed, every time

At a speed of more than 100 kilometers per second, it will take them nearly 20 days to arrive. If the acceleration and deceleration time is added, it will take them at least nearly a month to reach the outskirts of the asteroid belt.

…

"Captain! We are about to reach the edge of the asteroid belt. Do we need to slow down?" After nearly a month of flight, the Ziweixing 1 space exploration spacecraft is finally safe and is about to reach the asteroid belt.

However, since the width of the asteroid belt is very large, some of which are nearly 1.5 astronomical units wide, in fact, the density of asteroids in the outer reaches of the asteroid belt is not high, and can even be said to be very rare.

But at this time, Wang Wei and his spacecraft were still quite fast. Although they had already experienced a slowdown, their speed still reached nearly 70 kilometers per second. Flying in the asteroid belt at such a high speed,

Even the outer reaches of the asteroid belt are quite dangerous.

Because at such a speed, as long as there is a meteorite with a diameter of more than 50 cm, it is enough to destroy their entire spacecraft, and in the entire asteroid belt, there are countless meteorites with a diameter of more than 50 cm, so if it is used like this

At such speed, it would be too dangerous to rush directly into the asteroid belt.

"Immediately reduce the speed to about 20 kilometers per second." Wang Wei, as the captain, was of course very aware of this situation, so he immediately ordered.

Following Wang Wei's order, the spacecraft began to slow down.

The asteroid belt is located in the solar system, a dense area of ​​​​asteroids between the orbits of Mars and Jupiter. The distance from the solar system and the core sun is approximately 2.17 to 3.64 astronomical units, and the overall width is about 1.5 astronomical units.

According to previous detections by human civilization, there are as many as 500,000 asteroids in the densely packed interior of the entire asteroid, of which more than 120,000 have been numbered.

Of course, although within the asteroid belt, the number of asteroids in the dense area alone is as high as more than 500,000 grams, but compared to the vast space of the entire asteroid belt, the density is actually not that high.

In the past nearly half a century, human civilization has actually launched several space vehicles to pass through here safely without any accidents.

As the speed of the spacecraft was finally reduced to a safe range, Wang Wei and the others also began to launch a large number of micro-satellites towards the asteroid. These satellites have different functions, including resource detection satellites, magnetic field detection satellites, and infrared detection satellites.

Water resources exploration satellites, etc.

These large numbers of satellites will help Wang Wei and his spacecraft explore the route of the asteroid belt before their spacecraft enters the asteroid belt, and explore the resources on the asteroids inside the asteroid belt, so as to provide humans with the opportunity to mine the asteroid belt in the future.

Various resources provide data.

"Captain, according to the data, we seem to have entered the outskirts of the asteroid belt. However, according to the display of the spacecraft's detection instruments, within a radius of nearly one million kilometers centered on our spacecraft, no object with a diameter exceeding 10

There are asteroids above 10 meters. Is it because the data we provided before was wrong? We have not reached the asteroid belt yet." After the spacecraft entered the outer reaches of the asteroid belt, a staff member on the spacecraft asked Wang Wei with some doubts.
