The picture shows the rocket recovery
Nowadays, many countries attach great importance to space technology, the cost of each space launch is as high as hundreds of millions of yuan, in addition to the cost of satellites, rocket cost also accounts for a large part, and after the rocket launch can only crash? China has broken through a new recycling technology, more ingenious than Musk's starship, the original domestic plan to use tethered hanging recovery rockets, for China's recycling technology to create a new high, but also let the majority of netizens can not help but say, simply than the United States starship more cattle, rocket recovery technology is the United States Space Exploration Technology Company, launched the "Falcon" 9 rocket, successfully sent the "Dragon" spacecraft into the orbit to the International Space Station to verify.
Although the American Space Exploration Technology Company is a private enterprise, but its mastery of space technology is very developed, taking the Falcon 9 rocket as an example, this rocket will not crash immediately after the first launch, but will choose to separate from the second stage, using a reverse thrust to land, through the rocket thrust to reduce the speed of the fall, and the United States also built a recovery site at sea, so that the rocket can achieve a smooth landing at sea.
This process seems simple, but the technical difficulty of wanting to achieve is very large, after all, the rocket in the landing process, how to maintain stability is not an easy thing, even if the angle of a slight tilt, may lead to landing failure, not only that, it is also very high in the landing process of the environment requirements, neither can there be strong winds, but also can not have a big wave, otherwise it will increase the risk of rocket recovery failure, so the Falcon 9 rocket has also appeared many times recovery failure.
China is also vigorously developing rocket recovery technology, after all, with the increase in the number of space launches, the cost required is also greatly increased, it is worth mentioning that the service life of the rocket mainly depends on the engine, and the life of the general rocket engine can reach hundreds of hours, but a space launch process is often only a few tens of minutes, far from reaching the service life of the rocket engine, resulting in a lot of waste, if the rocket engine can be well preserved, and put into use again, Then the cost savings that can be saved every year will be a huge amount of money.

Domestic rocket recovery technology, on the basis of the Falcon 9 has been greatly improved, the rocket first by pushing back to reduce the speed, and then wait until it falls to a predetermined height, into the tether hanging facilities, by adjusting the angle and direction of the tether suspension, successfully hook the hook at the top of the rocket, so as to achieve the purpose of deceleration, it has a larger operating space than the Us rocket recovery technology, and the safety is higher.
Being able to develop this rocket recovery technology fully demonstrates China's creativity in the field of aerospace, and once this technology matures, it can greatly reduce the cost of space launches, which is conducive to China's deployment of the next stage of the space program, while the Falcon 9 rocket recovery technology mastered by the United States is not in the flow at all, coupled with high risk, it is simply not comparable to China's technology.
