It's so outrageous. As soon as the 93rd military parade ended, our mother was preparing to plan to hit an asteroid. Before I could recover from the shock of Dongfeng 61's global coverage, the times have already stepped into the "Defend the Earth" plan. Today we will talk in a simple way, what is the sea of stars and what is the defense of the Earth?
Speaking of this, it is actually a bit terrifying to think about it carefully. I just finished the military parade and proposed this plan. During the US-Soviet Star Wars, the Soviet Union was fooled and lame. Now history seems to be about to repeat itself. So the question is, who fooled who again this time?
The full name of this plan is "Near-Earth Asteroid Defense Mission Plan". It was originally announced on April 25, 2023. The plan will achieve kinetic energy impact on asteroids in 2030. This plan is not only us, but NASA has also announced a similar plan. By the way, I have also prepared a plan: Everyone raises his hands, pays attention to it, and accompany my country to counterattack together.
Two years ago, 10 asteroids were initially selected, with the largest diameter being 89 meters and the smallest being 24.3 meters. However, the distance of the last selected target asteroid relative to the earth is required to be moderate, the orbital inclination is not greater than 7°, and the eccentricity is not greater than 0.6. There are at least one observation opportunity in China before the impact. All telescopes in China can see it during the impact. After the impact, there will be at least one observation opportunity in three years.
According to Academician Wu Weiren's introduction this year: China is preparing to adopt the "flying + impact + flight" mission mode, and then impact the asteroids 10 million kilometers away from the earth, to remove the risk of the target asteroid hitting the earth in the next hundred years. Does this sound particularly like a science fiction film?
But science fiction films have come to reality, and CCTV also released videos as evidence.
The mission to defend the earth is not a big talk. Asteroids are still very dangerous. The earth is also called Blue Star. Because the ocean area accounts for a large proportion, looking at the earth in the distant outer space is like a blue planet. After the asteroid hits the earth, it will trigger a tsunami, melt the earth's crust material, cause a large amount of dust, cover the sky, and cause large-scale acid rain, seriously destroying the ecology. The former earth overlord dinosaur was extinct.
A 65 million years ago an asteroid hit the earth, producing huge shock waves and heat waves, which not only caused forest fires and severe earthquakes, but also caused huge tsunamis and dust covering the world, causing more than two-thirds of the creatures on the earth to become extinct, and dinosaurs are one of them.
Since the last century, craters have been constantly discovered on Earth by scientists, such as those found in the Yucatan Peninsula in Mexico. This crater was formed in the Cretaceous and the end of the Tertiary period, with a diameter of about 200 kilometers. It is said that this is the asteroid ruins that caused the extinction of dinosaurs. There is also a 50,000-year-old asteroid ruin in Arizona, USA. In 2013, a meteorite entered the atmosphere and exploded over the city of Chelyabinsk, Russia, causing thousands of injuries.
All signs are proving one thing: an asteroid hitting the earth may destroy human civilization. At this time, we have to talk about the community with a shared future for mankind.
What is a community with a shared future for mankind? All capable countries have the responsibility to prevent such destruction of the world and the earth from happening. How can there be a complete egg in the end? Putting all your time and energy into the knife instead of spending money and hegemony in the hegemony of grabbing oil is called responsibility for a great power, also called responsibility.
I say that destruction of the world is not an exaggeration. The fact that the Americans sent Japanese mushroom bombs is all pediatrics in front of this. Scientists have long given simulation experiments. When an asteroid with a diameter of more than 1 kilometer hits the earth, a crater of 15-20 kilometers will form and trigger a major earthquake around the world. Seventy percent of cities in the world cannot withstand this kind of impact. Just impact is the smallest damage, and the subsequent chain reaction is even worse.
After the impact, more than 5 billion tons of dust and sulfate aerosols will be injected into the Earth's stratosphere. Then, under this influence, the global temperature will continue to drop for three to five years, with a drop of about ten degrees. Many plants will become extinct in this temperature difference and the earth's ecosystem will collapse.
At this time, the deep-sea system can still be maintained. The problem is that humans have little hope of survival in the deep-sea, and the extinction of plants on land will lead to food production reduction.
The food that can be eaten by humans is cultivated in a greenhouse. The greenhouse needs electricity supply, so the premise is that the planet hit the earth without causing large-scale damage to the power system. Then there is acid rain and ozone layer damage, which will last for several years. When what I said happens at the same time, 90% of ordinary people on the earth will no longer exist. At this time, human civilization can only retreat, and the hope of restoring human civilization can only be placed on a small group of people.
No one wants this to happen, right? Of course, we don’t want it. All countries in the world don’t want this to happen, so space agencies in various regions are closely monitoring these asteroids. In 2024, NASA and the European Space Agency jointly announced a news that the orbit of a near-Earth asteroid named 2024 YR4 has changed
The diameter of this near-Earth asteroid is about fifty meters, and the risk of impacting the earth has increased by one percent. This year, the probability of this asteroid hitting the earth has reached three percent.
Later, there was news that the probability of this asteroid hitting the moon is relatively high. No matter what, everyone is responsible for defending the earth. You must participate in this matter. If you don’t participate, how can you show the strength of China’s aerospace and not show your practical strength? How can you know that you have strength? To put it bluntly, it is similar to the military parade.
Besides, look at the NASA, one ppt a day, and this matter must be followed. The strength to impact asteroids also represents the strength to impact a satellite. When there are asteroids, it is to defend the earth. When there are no asteroids, it is to defend the country.
In September 2022, the United States used a 0.6-ton spacecraft to actively impact an asteroid in low-Earth orbit at a speed of 6.6 kilometers per second. Thirty years ago, the United States also put forward a slogan, fighting all over the world in an hour. In the last century, after decades of expansion, the Soviet Union's military finally reached its peak.
Let me put it this way, the total number of ballistic missiles, submarine-launched missiles, and nuclear warheads exceeded that of the United States, which means that they had a nuclear advantage over the United States. At that time, the United States was also trembling with fear. After all, they had just emerged from the dilemma of the economic crisis and were really afraid that the Soviet Union would really play nuclear deficit. That was a fighting nation, but the United States had to follow up. As the saying goes, one mountain cannot accommodate two tigers, unless one male and one female.
The young Americans are much smarter than now. Compared with the Americans, the Soviet Union is like a brainless guy. The Americans have also thought about it and cannot be led by the nose. If the Soviet Union wants to engage in military affairs, we will do the economy. Since it is not possible to be strong in military affairs, then let's take a detour. I will spend 100 million US dollars to build an anti-ballistic missile system. Since you have already made so many nuclear bombs, I will intercept your nuclear bomb. If you don't want to blow it up, you will be the one who has the headache in the end.
The Soviet Union was really troubled when he saw the plan proposed by the United States. After so long, it was intercepted by others. Isn’t that a waste of time?
In fact, according to the technological level at that time, the United States really might not have been able to do this. It was just a big pie for the whole world from the perspective of the US-Soviet battle.
Whether this cake is delicious depends mainly on whether the country has the strength. If it is very empty, this cake is a bad heart. Everyone should be familiar with the movie "Star Wars" series. In the year when "Star Wars 6" was released, US President Reagan delivered a TV speech at the White House, titled "Peace and National Security". Reagan told all Americans "I am taking the first important step...
To develop a long-term research and development plan to achieve our ultimate goal of ultimately eliminating the threat of strategic missiles, I believe that the efforts we set out tonight have hope of changing the course of human history”
In October of the same year, the US Department of Defense proposed the famous anti-ballistic missile program "Strategic Defense Initiative" based on the spirit of Reagan's speech. The United States should use space as its main base to deploy laser, particle beam, electromagnetic guns and other weapons, combine ground and air defense weapons to form a multi-level deep defense system to intercept ballistic missiles launched by the Soviet Union layer by layer, and destroy all or most of them before the missile flew to the United States. At the same time, in the 1980s, the US Department of Defense judged that the Soviet Union lags ten years behind the United States in computer electronics, and there is a gap with the United States in many key areas such as electro-optical sensors, robotics, signal processing, and communication technology. If you want to catch up, you must spend money hard. Economically, the Soviet Union could not bear it. The Soviet Union was following up with the Manhattan Plan and the Apollo Moon Landing Plan that were previously constructed, and the Soviet Union was trapped in the quagmire of Afghanistan.
It can be said that there is wars that continue to bleeding outside, arms races that continue to invest in, the domestic economy shrinks across the board, and the bread doesn't care about fullness, and what kind of heels are used. Even if you use it as a shorts, can you keep up?
The Soviet Union originally wanted to admit defeat quietly, hoping that the United States could keep the "Star Wars" plan in the laboratory. The United States was excited when it heard it. Then I must do it. I don't do it. How can you disintegrate the Soviet Union?
After the collapse of the Soviet Union, the United States did not give up on Star Wars, but just changed the "comprehensive" to a limited key interception. At this time, we have to repeat the sentence "Dongfeng 61, global coverage" three times. The United States' PPT Dongda University is seriously studying it. This is so bragging and encountering the honest. In the future, based on Star Wars, the United States has put forward a lot of ppts
For example, the AIM-120D air-to-air missile is said to use a cross-age dual-pulse engine, with doubled range, improved accuracy, and high end storage speed and strong maneuverability. That means to hit wherever you want, very very powerful.
Dongda University saw that the United States was so strong, so we couldn't fall behind. Then the double-pulse solid rocket engine missile - Pili 15, emerged from nowhere. The United States was confused when it saw it. I'm asking for money. Are you really playing?
Is this the difference between capitalist society and communist society? I look at the money, you look forward, there is also the F22, the lift coefficient of the United States has reached 1.5, and it claims to be 2.0. Dongda University is even more anxious when it comes to seeing it. Why are you so awesome? You have to follow. So the "lift body edge strip wing duck-like layout" emerged again, with a lift coefficient of 2.2
Tongda University can finally feel at ease. The Americans can't sit still, are you playing it again? Is it wrong to get the script of the US-Soviet battle?
We are quite nervous about the US-based spacecraft hitting an asteroid in low-Earth orbit. What if it is not an asteroid hitting it, it is Beidou?
This involves another problem. Once the Beidou is knocked out, will Chinese missiles become blind? Navigation satellites are too important to a country. Without it, any weapon and equipment is like having no eyes. And the Galaxy incident back then, that is the sting in the hearts of every Chinese. Let me say that, if you lose the Beidou, China's weapons will not become blind. Maintaining national security is definitely no problem, but this matter must not be gambled.
It is better to bet on your own strength than bet on the conscience of the United States.
The near-Earth asteroid hit by the United States is at a speed of 6.6 kilometers per second, and even the first cosmic velocity required to operate in the earth's orbit is 7.9 kilometers per second, and it cannot reach the second cosmic velocity required to break away from the earth's orbit. In other words, this is not intended to impact the asteroid at all, but to impact satellites in other countries.
The impact distance we chose is 10 million kilometers away, far exceeding the 384,000 kilometers of the earth and the moon, which is definitely more than the second universe speed. This is the technology that can truly impact asteroids. They themselves know what the NASA wants to do. Anyway, we are really defending the earth and showing our strength. Sometimes, technology is just a knife.
In the hands of a murderer, that is the tool for the crime, and in the hands of a chef, that is the guy who cooks.
I hope the United States can keep up in this game. After all, from the perspective of the United States' usual thinking, there can only be one Hao Nan brother in the global village.
Finally, we will look at what Academician Wu Weiren said: "For the extremely small probability and extremely harmful event of near-Earth asteroid impacting the earth, we will perform kinetic energy impact on an asteroid of tens of millions of kilometers to change its orbit, and conduct an impact effect evaluation in orbit, so that it can be achieved, accurately impacted, pushed, measured, and explained clearly."
In other words, Ying Jiang, don’t use the Beidou satellite, we will also hit it accurately.
