Homo sapiens.

Galaxy 4, February 5nd.

Solar system, edge of the Kuiper belt.

A spacecraft whose speed has soared to 570 kilometers per second is rushing towards the vast starry sky.

The spacecraft is called the "Cicada-class Spaceship" and belongs to the Interstellar Exploration Office of the Space Division of Homo Sapiens.

This type of spacecraft is about twice the size of the Tinder class, and when it departs from lunar orbit, it has a total mass of 1.4 tons.

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

At this time, the back of the cicada-class spacecraft continued to eject miniature hydrogen bombs.

Then a flash of light exploded the lid of the propelling pot behind the spaceship, and the speed of the spaceship increased by several kilometers per second.

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

There are synchronous robots on the cicada-class spacecraft, and a synchronous communication system with magnetic monopole crystals.

In the current test, the communication delay of the magnetic monopole crystal has not changed, it is still 0.034 nanoseconds as before.

The communication effect is very powerful.

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

Homo sapiens uses the violent method of nuclear explosion propulsion to violently increase the speed of the cicada-class spacecraft to the current level, which solves the speed bottleneck of the previous detectors.

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

After all, electromagnetic wave communication is not too obvious within a radius of 30 kilometers, but once the communication distance exceeds 30 kilometers, the obvious delay will become more and more serious.

This is also the fact that the various forces on the earth in the past, in the process of exploring outer space, as long as they leave the spacecraft of the earth-moon system, they need relatively high artificial intelligence to assist the spacecraft, otherwise it is easy to go wrong.

Only Homo Sapien, which solved the two problems of speed and communication, dared to launch a detection spacecraft outside the solar system.

At this time, the five pilots driving Cicada-class 001 were also busy in the cockpit through the synchronous robot.

The destination of this cicada-class spacecraft is the old neighbor of the solar system-the Proximity system.

However, the distance between the two sides reaches 4.2 light years. Even if the Cicada-class spacecraft exhausts all the propelling hydrogen bombs, the maximum speed can only reach about 1200 kilometers per second, which is 0.4% of the speed of light.

This speed is said to be fast, and it is indeed very fast.

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

Flying to Proximity at this speed, it will take 1050 years to reach Proximity.

Obviously this time is really too bad.

Of course Homo sapiens did not aim too high. After all, the magnetic monopole crystal has a limited service life, which can only be used for about 15 years at most.

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

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

What's more, the Homo sapiens company doesn't have many real opponents on the earth now, 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 the sun is unlikely to have major problems in the next few hundred million years or so.

Therefore, the most likely danger that Homo sapiens company will encounter at present can only come from outside the solar system.

Of course, this kind of danger does not necessarily have to be alien civilizations. It may also be a gamma-ray burst that just swept through the solar system, or a wandering planet hidden in deep space.

First of all, the probability of encountering alien civilization and human civilization is very small.

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

If the other party invented super-light-speed transportation technology, it would basically fall into the category of a 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 and wandering planets in interstellar space.

The former is the product of a supernova explosion. Since the speed of gamma rays is the speed of light, it is basically impossible to guard against for previous human civilization. If you are really unlucky and encounter gamma rays, you can only resign yourself to fate.

Now Homo Sapiens’ solution is to arrange some early warning detectors in the void at the edge of the solar system. Magnetic monopole crystal communicators will be installed on the detectors to ensure that the information can be fed back to the earth headquarters in time.

Without the synchronous communication of the magnetic monopole crystals, there is really no way for gamma rays to know the situation in advance.

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

The origin of these wandering planets is that many planetary systems collided or merged with each other, and only a part of the planets were thrown into the interstellar space, thus forming wandering planets.

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

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

During the flight, the six Cicada-class spacecraft discovered many asteroids in the Kuiper Belt.

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

It is precisely because of the concealment of the wandering asteroid that Homo sapiens needs to know the situation outside the Kuiper belt to avoid being in a hurry.

Don't think these asteroids are not dangerous, in fact they are very dangerous.

Among them, the huge asteroids, or wandering planets, are very dangerous to the solar system.

Once wandering asteroids or planets enter the inner solar system, it is very likely to cause abnormalities in the major planets in the inner solar system.

In the early days of the solar system, asteroids and rocky planets collided with each other. Otherwise, where did the pockmarked face of the moon come from?
Venus was hit by other planets in ancient times and its axis and rotation direction were distorted, which caused Venus to rotate extremely slowly.

The planet's slow rotation speed will cause the geomagnetic field to not be strong enough to resist the erosion of solar storms. Finally, Venus became the ghost it is now.

Homo sapiens does not want the earth to repeat the same mistakes, so in the future, it needs to gradually improve the monitoring of the outer solar system, so as to avoid emergencies.

Just now.

Cicada-class 004 has been flying above the solar system for more than ten months.

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

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

Not to mention planets and the like, even ice crystal asteroids are very rare in scale. So far, Cicada-level 004 has not found too big a target.

But during this boring flight, the siren in the cockpit immediately sounded.

Everyone looked at the content of the alarm, and suddenly they couldn't help being ecstatic, because the spaceship was about 24 kilometers away...
