Galaxy 4, May 1.

Solar system, edge of the Cooper belt.

A spaceship, which has soared to a speed of 570 kilometers per second, is hurtling towards the vast starry sky.

The spacecraft is called the "Cicada-Class Spaceship" and is part of the Office of Interstellar Exploration of Homo Sapiens' Space Division.

The spacecraft of this model is about twice as large as the Tinder class, with a total mass of 14,000 tons when it departs from lunar orbit.

However, the core of the Cicada-class spacecraft is a large number of miniature Firefly hydrogen bombs, and it is with so many miniature hydrogen bombs that the Cicada-class spacecraft flew from the moon to the edge of the Cooper Belt in 11 months, and increased its speed to 570 kilometers per second.

At this time, behind the Cicada-class spacecraft, miniature hydrogen bombs continued to be spewed.

Then a flash of light exploded on the lid of the propeller behind the ship, increasing the speed of the ship several kilometers per second.

If you lock onto the cicada-class spacecraft through an astronomical telescope, you can find a series of points of light behind it, and then fly out of the solar system at a high speed.

At present, Homo sapiens has launched a total of 6 cicada-class spacecraft, which are divided into six directions: southeast, northwest, and up and down, flying outside the solar system.

The cicada-class spacecraft has a synchronous robot and a synchronous communication system with a magnetic monopolar crystal.

In the current test, the communication delay of the magnetic unipolar crystal remains unchanged, still at 0.034 nanoseconds as before.

This communication works very well.

For deep space probes, the first challenge is speed, and the second is communication delay.

Homo sapiens used the berserk method of nuclear explosion propulsion to violently increase the speed of the Cicada-class spacecraft to the current level, solving the speed bottleneck of previous probes.

The synchronous communication of magnetic unipolar crystals solves the communication problem in the process of deep space exploration.

After all, electromagnetic wave communication is within a radius of 300,000 kilometers, which is not too obvious, but once the communication distance exceeds 300,000 kilometers, the obvious delay will become more and more serious.

This is also the previous earth's various forces, in the process of outer space exploration, as long as they leave the spacecraft of the Earth-Moon system, they need relatively high artificial intelligence-assisted spacecraft, otherwise it is easy to have problems.

】

And Homo sapiens, which has solved the two problems of speed and communication, dares to launch a probe spacecraft beyond the solar system.

At this time, the five pilots who piloted the Cicada-class 001 were also busy in the cockpit through the synchronization robot.

The destination of this Cicada-class spacecraft is the old neighbor of the solar system, the Proxima system.

However, the distance between the two sides reaches 4.2 light years, and even if the Cicada-class spacecraft exhausts all the propulsion hydrogen bombs, the maximum speed can only reach about 1,200 kilometers per second, or 0.4% of the speed of light.

It's fast, it's very fast.

But for the distance between planetary systems, it seems insignificant.

Flying towards Proxima at this speed would take 1050 years to reach Proxima.

Obviously, this time is too pitiful.

Of course, Homo sapiens is not ambitious, after all, magnetic unipolar crystals have a limited service life, and can only be used for about 15 years at most.

Therefore, the mission of the Cicada-class spacecraft is to explore the deep-space interstellar space along the way, laying the foundation for more in-depth exploration in the future.

Human beings still have too little understanding of the deep space beyond the ancient cypress belt of the solar system, which is not conducive to human beings going out of the solar system in the future.

What's more, now Homo sapiens has not had many real opponents on Earth, unless the sun suddenly explodes one day, it is possible to wipe out the human civilization in the solar system.

The sun is still in its prime, and it is unlikely that there will be major problems with the sun for the next few hundred million years or so.

Therefore, the most likely danger to Homo sapiens at the moment can only come from outside the solar system.

Of course, this danger does not have to be an extraterrestrial civilization, but it could also be a Gamma ray storm that just swept through the solar system, or a wandering planet hidden in deep space.

First of all, the probability of an encounter between an alien civilization and a human civilization is not very high.

After all, the solar system is not in the central region of the Milky Way, but on the spiral arm, and the other planetary systems around it are very far away, even if it is the nearest neighboring system, it is very difficult to fly over the solar system.

If the other party invents faster-than-light transportation technology, it will basically be in the category of second-level civilization, and there is no need to embarrass a quasi-first-level civilization.

Therefore, the future crisis of Homo sapiens can only come from Gamma-ray bursts in interstellar space and wandering planets.

The former is the product of a supernova explosion, and because the speed of Gamma rays is the speed of light, it is basically impossible to prevent for previous human civilizations.

Now Homo sapiens' solution is to arrange some early warning probes in the void at the edge of the solar system, and the probes will be equipped with magnetic monopole crystal communicators to ensure that the message can be fed back to the Earth headquarters in time.

Without the synchronous communication of the magnetic monopole crystal, there is really no way to know the situation in advance.

As for wandering planets, this is not nonsense, but in the dark interstellar space, there are indeed a few wandering planets.

The origin of these wandering planets, many of them are caused by the collision or fusion of planetary systems with each other, which threw some planets into interstellar space, thus forming wandering planets.

And this kind of planet abandoned by the parent planet system, because it does not emit light itself, naturally in the astronomical telescope, there will be no too obvious signal traces.

There may be fewer planetary-level wandering planets, but there are many asteroid-level planets.

Six cicada-class spacecraft discovered a number of asteroids in the Cooper Belt along the way.

These unknown asteroids are often elusive, and without magnetic field probes, it is really difficult to lock on to these asteroids.

It is precisely because of this hidden nature of the wandering asteroid that Homo sapiens needs to know the situation outside the Cooper Belt and avoid being in a hurry when the time comes.

Don't think these asteroids aren't dangerous, they're actually very dangerous.

Among them, large asteroids, or wandering planets, are very dangerous for the solar system.

Once a wandering asteroid or planet enters the interior of the solar system, it is very likely to cause abnormalities on the major planets in the solar system.

In the early days of the solar system, there were asteroids and rocky planets colliding with each other, otherwise where did the pockmarked face of the moon come from?

Venus was knocked by other planets in ancient times, and its axis and rotation direction were distorted, resulting in an extremely slow rotation of Venus.

The slow rotation of the planet will cause the geomagnetic field to be weak enough to resist the erosion of solar storms, and finally Venus will become what it is now.

Homo sapiens does not want the Earth to repeat the mistakes of the past, so it needs to gradually improve the monitoring of the outer layers of the solar system in the future to avoid unexpected events.

Right now.

Cicada 004 has been flying above the solar system for more than a decade.

Inside the cockpit of the spacecraft, several pilots looked at various monitoring data, hoping to find useful data.

It's a pity that in the void above the solar system, it is really too desolate.

Not to mention planets and the like, even ice crystal asteroids, the scale is very rare, and so far the cicada-class 004 has not found a big target.

But during this boring flight, the sirens inside the cockpit immediately went off.

Everyone looked at the content of the alarm, and they couldn't help but be ecstatic, because the front of this spaceship was about 240,000 kilometers away......
