As we all know, today's United States completely regards China as a target of space competition. While worrying about being exclusive to China's lunar resources, it also hypocritically proposes Sino-US cooperation. The best way to do this attitude of the United States is to ignore it and follow China's own space path. However, NASA does not seem to be planning to give up entanglement. Not only does the moon landing site "collide" with China, but the asteroid defense plan is also similar to China. Just recently, NASA successfully hit an asteroid with a detector at a location 11 million kilometers outside the ground.
This is the first time in human history that I have tried to change the movement of celestial bodies. Based on this alone, NASA has created history again. The impact mission has been completed, but whether the orbit of the asteroid has shifted still needs to wait for further measurements from astronomers. If the orbit is confirmed to change, then humans will master the defense capabilities of extraterrestrial celestial bodies in the future. Although China has proposed the "asteroid defense" plan, it is still implemented first by the United States. Does this mean that China's skills are not as good as humans? It has to be admitted that my country is indeed still in a gap with NASA, but this is normal.
After all, China's aerospace development has just begun, and it is not easy to achieve today's achievements under independence and independence. Moreover, although China and the United States have defense plans, the content is completely different. China's plan may be higher than the United States' starting point. NASA uses the kinetic energy deviation mode of the impact body this time, using the kinetic energy of the artificial satellite itself to knock it away, which requires a larger weight of the satellite , otherwise it will not be able to generate huge kinetic energy. NASA successfully hit the asteroid's satellite this time, weighing up to 610 kilograms. When facing larger celestial bodies, it may require multiple detectors to successfully hit.
But China plans to use the "last-stage rock strike" method to impact. The impact body and rocket will not separate, which can generate greater kinetic energy, and the interception probability is far greater than that of the detector. It can also be said that China uses direct launch of rockets to impact, which has good results and fast reaction speed, but it also requires higher technology and spacecraft control level. As long as China can advance the plan as scheduled, it will definitely have the advantage of latecomer. So there is no need to worry about whether the United States is taking the lead. If it really hopes to defend against asteroids hitting the earth, it will be a great thing for the whole world.
But if the US has bad intentions and uses this to develop dangerous weapons, then countries around the world should remain highly vigilant. After all, according to the US's style of conduct, what can't be done? Moreover, it has established space forces, and the deployment in space may be far beyond the outside world's imagination. In addition, if this technology is really successful and used in the field of weapons, it will be a disaster for the whole world. In the face of a common crisis of mankind, the US should also give up selfish desires. Doing unjustly will kill itself, and a community with a shared future for mankind is hoped that the US can deeply understand these two points.
