How far is China rocket from reuse?

Looking around the world, only elon musk's Falcon rocket has achieved a low-cost and reusable launch vehicle. In the past five years, the recovery of rockets on land and at sea has been regarded as a typical successful case in the field of commercial aerospace, which has once again ignited the dream of human beings moving to Mars.

Now, the verification of China's rocket recycling technology has taken a small step. How far is it from real rocket reuse?

Cheap and efficient, more safe.

The so-called reuse of the launch vehicle means that the booster, a certain sub-stage and other components of the rocket can return safely after launch and can be reused after renovation. This seemingly sci-fi idea has not only become a reality, but also become a new stage for the development and wrestling of various space powers.

As for the reason, low cost is the first knowledge in the industry.

According to the report released by the National Aeronautics and Space Administration (NASA), the same Falcon -9 rocket needs at least $654.38+03 billion to be developed by NASA, while commercial companies only spend less than $400 million.

Therefore, some people commented that elon musk, a commercial space leader with hundreds of millions of fans, lowered the price of space launch by an order of magnitude.

An aerospace expert told China Youth Daily and China Youth Network that Elon Musk's commercial company won the favor of the aerospace market with low-cost products. Their Falcon -9 rocket won 38 launch contracts worldwide in the next five years, among which 24 were from the international commercial launch market except the government's 14 contract. 2065438+In May 2005, this company was also qualified to carry out the space launch mission of the US military.

While the cost is reduced, the efficiency is also improving.

First, the development cycle is shortened. Falcon 9 took only four and a half years from design to first flight. Second, technological innovation has accelerated. Falcon -9 has carried out a series of reusable rocket tests, and both land and offshore platform recovery tests have been successful. The expert told reporters that the establishment of a flat organization by commercial aerospace management institutions has greatly shortened the management chain.

For China at present, this matter has more practical significance-security issues.

According to He Wei, Assistant Minister of the First Design Department of the First Research Institute of China Aerospace Science and Technology Corporation, in recent years, the high-intensity and high-density launch of launch vehicles in China has become the norm, especially in 20 18 years, with the number of launches reaching 38 times, ranking first in the world. The safety problem of rocket debris landing zone has attracted more and more attention.
