Voyage of the Stars

In fact, some humans have also raised such concerns, that is, they are afraid that the Nair civilization will catch up and affect Chiyu. So after embarking on the voyage, someone proposed a mid-course diversion.

But a star map put an end to this idea.

It’s not that after the departure of the white giant star, humanity’s goal at this moment is the only option, but the nearest star in this direction. It is theoretically possible to divert to other stars midway. After all, humans have experienced thousands of years of voyages, but it is still a bit far away. I am afraid that if we go for another hundred years, the remaining supplies of the fleet will not be enough to cope with emergencies.

Moreover, some people have also raised another point, that is, if the Nair people really want to follow someone, then humans will be discovered even if they turn around.

Based on these two points, humans gave up the idea of ​​turning around midway.

Ever since, the balance of fate has allowed human civilization and Nel civilization to meet again in the next star system.

In the dark universe and the deep starry sky, when a steel fleet spurts out light from the darkness, the outline of the target star also appears in front of humans.

This is a very stable yellow dwarf star. It is only slightly larger than the sun. Its mass is about 1.1 times that of the sun. It has a G-type spectrum. It is the same type of star as the sun, but it is not exactly the same because there are no two stars in the universe. stars with identical spectra.

This star is a main sequence star like the sun. Its average surface temperature is 6000 degrees Celsius, which is much higher than the sun.

It is a star in its prime and can live for about nine billion years.

Unfortunately, inside it, there are no rocky planets in the habitable zone defined by human beings based on their own living environment standards. Not only is there no habitable zone, there are no rocky planets in other orbits, whether in far orbits or near orbits.

However, the absence of rocky planets does not mean that it is useless to humans. Humans have no way to obtain supply resources here, because it has two giant gaseous planets.

There are many rocky satellites in the orbit of giant gas planets.

The two giant gas planets are both more than 6 AU from the main sequence star. The average orbit radius at the closest moment is 6.6 AU, and the average orbit radius of the outer one is 12.3 AU.

The two gaseous planets are not much different in size, and both are earth-like planets. The diameter of the close orbit is 10 times that of the Earth, and the diameter of the farther one is 11.5 times that of the Earth. The two gaseous planets are only a little larger than Saturn, and the amazing thing is that these two gaseous planets have beautiful rings similar to the rings of Saturn.

When humans arrived, the two giant gas planets were orbiting on both sides of their main sequence stars. The moment they approached the direction of humans, they happened to be in close orbit.

Of course, humans did not enter the star system directly from the ecliptic plane of the main sequence star, but formed an angle of about 30 degrees, but no matter what, it was close to the one in the closer orbit.

Therefore, human beings did not abandon the near and seek the far away, and went directly to the rocky satellite of this giant gas planet. During the approach, astronomers made precise calculations and discovered that the orbital period of this giant gas planet is 13 years.

As for the outer one, because its orbit is longer and farther, its orbital period is longer. It takes 35 years to orbit its main sequence star.

The giant gas planet that humans have settled on has three rocky satellites, one of which has a very small mass and cannot form a sphere by itself. Its orbit is also a very flat ellipse, so humans choose to ignore it. Among the other two, the one in the farthest orbit is very large, with a diameter of 6011 kilometers, only smaller than Mars.

However, it orbits a giant gas planet, so even if it is large enough, it is still a satellite. As for the other one, it is smaller than the moon.

In this way, the choice of human resources extraction destination is naturally obvious, that is, both.

Both satellites belong to the common types of planets in the universe. They have no atmosphere and are silent in geological activities. They also look desolate and lonely.

This is the norm for many planets in the universe, and humans have long been accustomed to it. Therefore, they did not dwell too much on sadness and followed the resource development procedures to explore and mine these two satellites.

The space elevator was again released from the specially transported spacecraft, and at the end of the exploration, it was deployed on the two rocky satellites. Three space elevators were allocated to the larger one and two to the smaller one.

The main purpose of humans coming here is to mine more non-ferrous metals and various minerals to extract the required metals and then make them into armor-piercing projectiles for electromagnetic railguns. While making enough armor-piercing bombs, they also filled each spacecraft with the materials and fuel consumed by the fleet during its voyage.

According to the estimates of the production department, if there are sufficient supplies and all elemental metals and non-metals are not lacking, it will take about three years to fill the entire fleet's ammunition depot.

Of course, this starts from the moment production and shipment begins.

Coupled with supply and demand for exploration, mining, transportation, pre-processing, etc., this process will take at least five years.

In other words, after five years, humans can set off again and run away.

By then, if we come a few more times, neither the Nell civilization nor the virtual consciousness carrying the huge fleet will be able to catch up with humans.

Although humans don't know whether the Nel civilization is chasing its own route, they are not afraid of ten thousand, but afraid of the worst. Finishing the project early and running away early is the right way.

Based on this concept, humans entered the rapid mining process as soon as they arrived on this yellow dwarf star. And the estimated time of five years was also estimated under this situation.

Well, if everything goes well, if other miscellaneous things are included, it may take another year and a half for humans to arrive and leave.

But it doesn't hurt.

Because humans are still very confident in their own supply capabilities. As long as the Nair civilization fills up all kinds of supplies at the white giant star, it will definitely take them more than five years.

Of course, these are the conditions under which human think tanks predict that the Nair civilization will pursue them. If the Nair civilization does not follow the human route, or they escape separately, then there will be no problem.

However, what makes humans stunned is that it has just been the fourth year since they arrived at this yellow dwarf star, and the detector uncomfortably outside the star system received a familiar message.

When the detector transmitted the information back to the human main fleet, the new government knew at a glance that it was from the Nair. Not long after the information appeared, the detector then sent back an image.

That is the space 21 AU from the outermost orbiting gas planet of this star system, where an unexpected and very shameless fleet is slowing down.
