Half-immortal civilization

Calls from all over the world have found a master company. The probability is one in seven thousand, which is an extremely dangerous probability.Human beings cannot take risks and wait for God's decision.This is already the age of science and technology, and human beings already have means to restrict asteroids: space-based weapons!

On June 6rd, at 3:[-] a.m. local time in Huaxia, Zhao Qingyun, who is in charge of the safety of the master company, delivered a speech, saying that the master company will do its best to carry out the plan to destroy the asteroid.However, due to the incompleteness of the space satellite of the master company, it is impossible to lock the orbit of the asteroid, and international assistance is needed.

The first response was the United States. NASA monitors all the observed asteroids in space that are harmful to the earth almost all year round. After that, the United Kingdom also expressed its full support.By evening, more than a hundred satellites around the world had locked on to Apophis.

That night, the public channel of Master Company received all the known details of Apophis. Data from more than a dozen countries around the world made this information extremely accurate. Whether it was time, orbit, or even size, the errors were all within a thousand. Below one ten-thousandth; only the density cannot be measured.

Seeing this data, Zhang Jingyuan sighed speechlessly. If the whole world can unite, mankind is expected to truly enter the space age in five years, unlike the present, which is still in the transition from the space age to the space age.It's a pity that each has its own interests and demands, but they never thought that the power of unity is even stronger.Of course, the real world cannot be counted in this way, and there are more complicated ones.

Putting this matter aside, the master company urgently held a high-level meeting, and all high-level officials related to this matter were in place.At 11 o'clock in the middle of the night, the headquarters building of the master company was brightly lit, and on the big screen in the huge conference hall, a schematic diagram of the changing Apophis orbit was evolving.Of course, even though it is a schematic diagram, it is also extremely accurate.It's just that the master company of this meeting did not agree to the request of the world's public meeting, but discussed it internally.

Because in such a meeting, the core interests and secrets of the master company will inevitably be involved.

Now, except for Liu Haibo, who is performing missions in space, all relevant personnel are in place.Looking at the serious people around, Zhang Jingyuan suddenly smiled, "Don't be so nervous, there is still a month to go. Besides, it's not that Gaoshou Company has no experience in destroying asteroids. But this time what I thought of was not destroying asteroids, but :capture!
As the global space race accelerates, supplies on Earth have become increasingly strained.Just a few days ago, one-third of the mines in Africa have been declared exhausted, leading to a further increase in the price of global mineral resources, and greatly constraining countries such as Germany and Japan that do not have enough mineral resources.

So, this time I wondered if we could try to capture an asteroid.Even if they are all rocks, they are of inestimable value in space.For example, our current photovoltaic cells are mainly composed of silicon wafers, and the source of these silicon wafers is stone, which is extracted step by step from quartz sand.So even if the asteroids are all stones, because they are in space, they are also a mobile gold mine. It would be too wasteful to smash the asteroids directly.

The previous comets were nothing because they were mainly ice; but this asteroid is not only rocky, but also sent to our door on its own initiative, so we can't give up anyway.

More importantly, please see, according to the reflection analysis above, and through the comparison of the spectral wavelength and color position, we can find that the surface of the Apophis asteroid contains a large amount of iron.We don't even rule out that the asteroid contains a lot of iron inside.The role and status of iron need not be explained.

In fact, according to the current law of development, steel is still the most powerful weapon for human beings to conquer nature.The rest, whether it is titanium, aluminum, magnesium, copper and other metals, can only be regarded as decorative steel ornaments.

In addition, I analyzed that the earth's revolution speed is about 29.79 kilometers per second; Apophis approaches the earth at a faster speed than the earth, with a relative speed of 15 kilometers per second, and the real revolution speed is about 45 kilometers per second.

At this speed, if we first calculate the orbit of the planet and let the space shuttle accelerate in advance, we can completely capture the asteroid.

This is a gold mine sent to us by God!
Mu Xinghai, what do you think of this plan? Is it feasible? "

Soon, Zhang Jingyuan turned his gaze to Mu Xinghai who was in deep thought.In the field, this is an absolute expert in space shuttle piloting.Of course, Dongfang Ying, who was in charge of the design, was also not simple.

"I think it's feasible," Mu Xinghai replied a little slowly, "but, after we capture it, where do we put it? Is it dangerous to put it in the earth's orbit around the earth? And if it's put far away, it will be difficult to manage. .”

"This is not a problem. Just a few days ago, we have completed the development of the intelligent program. We can transplant a set of intelligent programs to control the space shuttle, and place two space shuttles on the captured asteroid to be responsible for adjusting the orbit at any time; according to With the current development speed of Master Company, by the end of this year, when the construction of the New Continent space base is completed, we will have the ability to deal with this treasure with our hands free."

"Well, I'll gather the boys and start the exercise now. But I guess it will be difficult to capture the asteroid." Mu Xinghai frowned, "I calculate that the weight of the asteroid is at least 4900 million tons, which is still calculated according to the weight of the rock. The texture is calculated; but we must be prepared in case, if it is filled with a lot of iron, the weight may reach 1.4 million tons. Of course, this is the limit weight; but the calculation must calculate the limit situation.

按照1.4亿吨重量计算，小行星速度45公里每秒；携带动能1.4175x10^21焦耳，约合电力3.9375x10^14度电。（通过这个数字可以看出小行星对地球的危害了；话说这个数字哥真心吓着了。不计算不知道。）
And it is impossible for the space shuttle to use up all the electric energy, so we calculate according to 4x10^14 kilowatt-hours of electricity, which is 40 trillion kilowatt-hours of electricity!But now, the electric energy carried by the newest and largest space shuttle Rise of the Master Company is only 6 million kilowatt-hours.Last year, the total global power generation was less than 90 trillion kilowatt-hours; China's own power generation was only a little over 9 trillion kilowatt-hours.

To be honest, this looks really difficult.

We need at least 660 seven sorties of the latest Space Shuttle Rise!

Personally, this is a number that can only be looked up to.

In addition, all aircraft need to be accelerated, and even need to carry a large number of steel cables, carbon fiber locks, etc., all of which must be counted, and the energy must be increased by at least one thousandth. "

Mu Xinghai's calculated data suddenly cooled Zhang Jingyuan's ambition.

"No, we should calculate like this." Dongfangying accepted Mu Xinghai's calculation results. "We should calculate the ability of the earth to capture asteroids in space. As long as the calculation is accurate, we can use the gravity of the earth to make the asteroid a satellite of the earth and orbit the earth.

The speed around the earth is 7.9 km/s, and the escape velocity is 11.2 km/s.In extreme calculations, Apophis can revolve around the Earth at a speed of 11 kilometers per second (near-Earth speed).

Secondly, the earth itself is also revolving around the sun at a speed of 29.79 kilometers, which cannot be lost.

According to the calculation of the current orbit of Apophis, there is a slight angle with the Earth's orbit, which can be ignored.Assuming that we make the orbit of Apophis around the earth parallel to the orbit of the earth, then the Apophis asteroid has the speed and energy of orbiting the sun with the earth in addition to its own orbiting speed and energy.

这样计算极限能量大约就是：0.5x1.4亿吨x（45000^2－11000^2－29790^2）÷3.6x10^6=1.97663647x10^13度电，约合2x10^13度电，为2万亿度电。（这个计算不知道对不对，请发现的大神帮忙计算下。）
Uh... well, it's still a little big, but it should be doable.That is, we need to be more cautious in the process, and there should be no mistakes in the calculation.

In addition, in fact, we calculated according to the iron core of Apophis. If the core is rocky, this number will be discounted by [-]%.

Moreover, there are currently 400 space shuttles in Gaoshou Company with executive capabilities. According to my calculations, all these space shuttles carry a total of 600 billion kilowatt-hours of electricity; and the batteries stored in Gaoshou Company have a full reserve of 1000 billion kilowatt-hours. In addition, we Full production in one month can reach 2000 billion kWh.And all aircraft can be modified, 400 space shuttles, if all the empty seats are filled with batteries, they can carry about 3000 billion kWh of electricity in total.

In addition, according to calculations, the country currently has about 5000 billion kWh of physical battery power storage, and there are about 300 Hiryu fighter jets, carrying about 100 billion kWh of power.The country is fully engaged in production, and can produce 4000 billion kWh in a month. All the Dragon space shuttles should be able to be refitted, and the total carrying power can be increased to 2000 billion kWh.

The sum of all space shuttles can carry 5000 billion degrees, and there will be 4700 billion degrees of physical batteries remaining.

In this way, the total amount of electricity is close to one trillion kilowatt-hours, and it should be possible to try it.But it needs to be discussed with the state.Simply relying on the master company itself, it is basically impossible to complete. "

Looking at these numbers, not to mention everyone, even Zhang Jingyuan was stunned!
Oh shit, I just want to play with a rock, as for it!
It feels wonderful, please collect and recommend.Many thanks.
