On the way back to the shell ecosystem, Dong Chen looked at the huge shell that was under construction, "One, do you have any tracking information about the recent asteroids around the earth here?" Is there an increase on the other side of the earth? ”

"Yes, sir, I'll sort it out for you, it will be more convenient for you."

Dong Chen's question was immediately answered positively by No. 1, and in the process of processing the information, No. 1 also said succinctly, "According to the data on the arc space side and the observation and tracking information of the space bureaus of various countries, in recent months, there has indeed been a problem with the operation of asteroids around the earth. ”

"The orbits of many asteroids begin to enter dense intersection areas, and then many asteroids will collide with each other, and this collision is uncontrollable, and some asteroids will be knocked into the Earth's orbit."

"This situation will not affect us much, but it will indeed have some impact on the space activities of the earth, because their observation equipment and computing equipment are not as advanced as ours, and the data recorded is not detailed enough, so this impact will gradually increase for them."

"Sir, the information is finished, please check ......"

"Well," listening to No. 1's concise explanation, Dong Chen had basically understood some of the situation, but some details still had to be seen by himself.

The information is more or less the same as the explanation of the first one, but there are some more detailed data to look at, and from here you can get a sense of the many changes that have taken place over this time.

The initial data changes started before the outbreak of the "Bloodshed" virus, but although these asteroids or debris have their own inherent orbits, they will change more or less every once in a while, so it is normal to have these changes.

However, with Dong Chen's sensitivity, he still saw the difference in it, after all, he was very concerned about this aspect of the matter now, and he had to include this item in the key observation project early.

According to the accurate data of arc space observation, in the past few months, the number of asteroids that have fallen into the earth's atmosphere has increased by 6%~8% compared with the same period before.

For nearly half a century, there have been an average of more than 700 meteorite falls per year worldwide. Of these, more than 3,000 occurred in 1979 and 1988.

However, it is worth noting that these are only asteroid impact events that fell to the ground and formed meteorites, and are documented and complete by the International Meteorite Society, the main purpose of which is to provide the official names of various meteorites and record the individuals certified by the Society.

Because many meteorites that fall in the sea or other uninhabited areas, as well as small meteorite falls that are overlooked, will not be recorded.

Such a high frequency of high-altitude falls may sound a little scary, but the casualties caused by meteorites are actually very small compared to the number of times a meteorite falls. The vast majority of meteorites shrink rapidly due to friction and combustion with the atmosphere, and finally the mass is only about 1 to 2 grams.

Therefore, the actual number of meteorites that fall to the earth every year may increase by tens or hundreds of times.

Even some asteroids can't land on the ground at all, and they burn up directly in the atmosphere, so the number of asteroids that rush into the earth's atmosphere every year must be several times higher than the actual number of meteorites.

In this way, this growth figure is quite impressive.

Again, it's pretty scary.

However, looking at these data records, Dong Chen found that the orbits of many asteroids did not change suddenly, but were meant to intersect, and what really determined the future direction was the result of their collision.

And this result is also the most difficult to calculate.

From this point of view, it is really possible that such a "bureau" started very early.

Sometimes Dong Chen also wonders what the truth of this world is like.

Is it a brain in a jar?

Is it a box?

Or a particle?

But when I think about it, I feel that I am full.

If you really want to know, when the level of the "novice village" of the solar system is cleared, you will know when you go out and take a look.

"Sir, in addition to the earth, the overall data on the moon side has also come out, and the relevant indices have also increased."

"There is also data on the asteroid belt, and the situation there is also a little different, the probability of collision between asteroids has become larger, and once this value becomes larger, there will be more variables after the collision, which may affect the Earth-Moon system."

Dong Chen quickly read the information synthesized by No. 1, and at the same time, No. 1 also gave a brief introduction next to him, giving him a general understanding of the entire solar system.

However, the current form is unclear, although he looks like a sign, but in fact, there is no hair, and he can't see anything, it's just that there are more asteroids, and the movement is a little more complicated.

“…… There haven't been any major impacts yet, so all we can do now is do the calculations and gather information until we have the exact information before we let me know. Dong Chen said after reading everything in general.

"Yes, sir, I'll keep an eye on that." Number One nodded beside him and said.

"Well, that's it," Dong Chen leaned on the seat of the car and sighed, "It seems that there will be another tough battle to be fought in the near future." ”

The road back to the "bubble" was not long, although the speed of the vehicle was not fast, but after Dong Chen and No. 1 talked about these things, they had already entered it through the airlock.

Just like when they left, they came back unnoticed by anyone.

Since these shell ecosystems are fully enclosed, the implementation here is still the earth time, and the display screen on the roof of the shell shows the alternation of day and night, so in addition to feeling light and fluttering, some impact on life, and occasionally falling on the ground, the living environment feels no different from the earth, and even better than where they lived before.

Occasional flat falls, that's what makes them get used to being here for a few days, and only after getting used to the gravity here can they get to work.

And they used to fly for a long time, so after coming here for a while, they all rested, and now this kind of sleep can not only replenish the spirit, but also allow the body to self-regulate during sleep, and further play a role in adapting to the environment.

So when Dong Chen came back, it was already quiet.

When Dong Chen learned about the asteroid, he planned to stay here for a few more days, of course, Sun Hao said that it must be indispensable after he found out.

However, after reminding Dong Chen to pay attention to safety, he agreed.

After Dong Chen and his new friends got used to it for two days, they were basically able to adapt to the gravity and living conditions here, and they also spent these two days taking a good look around this part of the open Moon City, which felt really incredible.

And Liang Guoyu, the general director of the moon of the Arc Group, also came, and began to officially manage the first city established by mankind on the moon.

And Dong Chen ...... Oh no, it's Dong Dui, he also got his first job on the moon, which was driving a moon bulldozer.
