Chapter 359 Unexpected

In fact, some humans have raised such concerns, that is, they are afraid that the Nair civilization will catch up and then harm innocent people. So after embarking on the voyage, some people proposed to turn midway.

However, a star map extinguished this idea.

It is not that after leaving the white giant, the current goal of mankind is the only choice, but the nearest star in this direction. It is reasonable to turn to other stars midway. After all, humans have experienced thousands of years of sailing, but it is really a bit far. I am afraid that if it takes another hundred years, the remaining supplies of the fleet will not be enough to deal with emergencies.

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

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

So, the balance of fate made human civilization and Nair civilization meet in the next star system again.

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

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

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

It is a star in its prime, and it can still live for about 9 billion years.

Unfortunately, there are no rocky planets in its habitable zone, which is divided by humans according to their own living environment standards. Not only is there no rocky planet in the habitable zone, but there are no rocky planets in other distant or near orbits.

However, the lack of rocky planets does not mean that it is useless to humans. Humans have no way to obtain supply resources here, because it is very powerful to have two giant gas planets.

And there are many rocky satellites in the orbits of giant gas planets.

Both giant gas planets are more than 6 astronomical units away from the main sequence star. The average orbital radius at the closest moment is 6.6 astronomical units, and the average orbital radius of the one outside is 12.3 astronomical units.

The two gas planets are not much different in size, and both belong to the Saturn-like planets. The diameter of the one in the near orbit is 10 times that of the Earth, and the diameter of the one in the farther orbit is 11.5 times that of the Earth. The two gas planets are only slightly larger than Saturn, and the amazing thing is that both gas planets have a beautiful ring similar to Saturn's ring.

When humans arrived, these two giant gas planets were running on both sides of their main sequence stars, and the moment they approached the direction of humans was exactly the moment of near orbit.

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

Therefore, humans did not give up the near and seek the far, and went directly to the rocky satellite of this giant gas planet. In the process of approaching, through the precise calculations of astronomers, it was found that the orbital period of this giant gas planet is 13 years.

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

The giant gas planet where humans have settled has three rocky satellites, one of which is very small 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 slightly smaller than Mars.

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

In this way, the choice of human resource mining destination is naturally obvious, that is, both.

Both satellites belong to the common planet type in the universe, with no atmosphere and dormant geological activities. They are still 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 explored and mined the two satellites according to the resource development procedure.

The space elevator was released from the special transport spacecraft again, and at the end of the exploration, it was arranged on the two rocky satellites, with three space elevators allocated to the larger one and two to the smaller one.

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

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

Of course, this should be counted from the moment of production and shipment.

Adding exploration, mining, transportation, preliminary processing and other supply and demand, this process will take at least five years.

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

If they come a few more times, neither the Nair civilization nor the virtual consciousness body carrying a huge fleet will be able to catch up with humans.

Although humans don't know whether the Nair civilization is chasing their route, they are better off safe than sorry. It is the right way to finish the work early and run away early.

Based on this concept, humans entered the rapid mining program as soon as they arrived at this yellow dwarf star. The five-year estimate was also made under this circumstance.

Well, this is when everything goes well. If other miscellaneous things are taken into account, it may take humans another year or two from arrival to departure.

But this is not a big deal.

Because humans are still very confident in their supply mobility, as long as the Nair civilization fills up all kinds of materials at the white giant star, the time they spend will definitely be more than five years.

Of course, these are all when the human think tank predicts that the Nair civilization will catch up. If the Nair civilization does not follow the human route or escapes separately, there will be no problem.

However, what shocked humans was that it was only the fourth year since they arrived at this yellow dwarf star, and the probe in the outer part of the star system received a familiar message.

When the probe transferred the information back to the human main fleet, the new government knew at a glance that it was sent by the Nair people. And not long after the information appeared, the probe then sent back a video.

That's 21 AU from the outermost gas planet in this star system, and there's an unexpected and very shameless fleet slowing down.
