Homo sapiens

Star River Year 4, May 1st.

Solar system, edge of the ancient cypress belt.

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

This spacecraft is called the "Cicada-class spacecraft" and belongs to the Interstellar Exploration Office of the Space Division of Homo sapiens Corporation.

This type of spacecraft is about twice as large as the Spark class. When it sets off from the lunar orbit, its total mass is 14,000 tons.

However, the core of the Cicada-class spacecraft is a large number of miniature firefly hydrogen bombs. It is with so many micro-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, miniature hydrogen bombs continued to be ejected from behind the Cicada-class spacecraft.

Then a flash of light exploded on the propulsion pot cover behind the spacecraft, and the speed of the spacecraft increased by several kilometers per second.

If you lock this Cicada-class spacecraft through an astronomical telescope, you can find that there is a series of light spots behind it, and then it flies out of the solar system at high speed.

At present, Homo Sapien Company has launched a total of 6 Cicada-class spacecraft, flying in six directions: southeast, northwest, up and down, and flying outside the solar system.

The Cicada-class spacecraft has synchronous robots and a magnetic monopole crystal synchronous communication system.

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

This communication effect is very powerful.

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

The Homo sapiens company used the violent 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 detectors.

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

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

This is also the case for various forces on the earth. In the process of outer space exploration, as long as the spacecraft leaves the Earth-Moon system, it needs relatively high artificial intelligence to assist the spacecraft, otherwise problems will easily occur.

Only the Homo sapiens company that has solved the two problems of speed and communication dares to launch a detection spacecraft outside the solar system.

At this time, the five pilots driving Cicada-class No. 001 were also busy in the cockpit through synchronized robots.

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

However, the distance between the two sides is 4.2 light years. Even if the Cicada-class spacecraft uses up all its propulsive hydrogen bombs, the maximum speed can only reach about 1,200 kilometers per second, which is 0.4% of the speed of light.

This speed is indeed very fast.

But the distance between planetary systems is insignificant.

Flying towards the Proxima System at this speed, it would take 1050 years to reach the Proxima System.

Obviously this time is too boring.

Of course, the Homo sapiens company is not ambitious. After all, the service life of magnetic monopole crystals is limited and 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 and lay the foundation for more in-depth exploration in the future.

Human beings still know too little about the deep space beyond the Cooper 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 Earth now. Unless the sun suddenly explodes one day, it will be possible to wipe out all human civilization in the solar system.

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

Therefore, the dangers that Homo sapiens companies are most likely to encounter at present can only come from outside the solar system.

Of course, this danger is not necessarily an alien civilization. It may also be a gamma ray burst that happens to sweep through the solar system, or a rogue planet hidden in deep space.

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

After all, the solar system is not in the center of the Milky Way, but on the spiral arm. The other surrounding planetary systems are very far away. Even the nearest Proxima Centauri system is very difficult to fly to the solar system.

If the other party invents super-light transportation technology, it will basically fall into the category of a second-level civilization. There is no need to embarrass a quasi-first-level civilization.

Therefore, future crises for Homo sapiens companies can only come from gamma ray bursts and rogue 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 was basically impossible to prevent it for previous human civilizations. If you are really unlucky enough to encounter gamma rays, you can only leave it to fate.

The current solution of the Homo sapiens company is to deploy 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 messages can be fed back to the Earth headquarters in a timely manner.

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

As for rogue planets, this is not nonsense, but there are indeed a lot of rogue planets in the dark interstellar space.

The origin of many of these rogue planets is that planetary systems collided or merged with each other, which threw some of the planets into interstellar space, thus forming rogue planets.

Since this kind of planet abandoned by its parent planetary system does not emit light, there will naturally be no obvious signal traces in astronomical telescopes.

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

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

These unknown asteroids often appear and disappear. Without magnetic field detectors, it is really difficult to locate these asteroids.

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

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

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

Once a stray asteroid or planet enters 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, there were collisions between asteroids and rocky planets. Otherwise, where did the pockmarked face of the moon come from?

Venus was knocked out of position by other planets in ancient times, causing its axis and direction of rotation to change, resulting in an extremely slow rotation of Venus.

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

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

Right now.

Cicada 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.

Let alone planets, even ice crystal asteroids are very rare in scale. So far, Cicada-class 004 has not found any big targets.

But during this boring flight, the alarm inside the cockpit immediately sounded.

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