According to a report from the World Wide Web on May 7, the time for the wreckage of the Long March 5B rocket to return to the ground is getting closer and closer, and the foreign media's hype about the loss of control of the rocket wreckage has become more intense. The US Department of Defense said on the 5th local time that it is currently tracking the rocket flight trajectory of the Long March 5 , but has not yet considered whether to intercept it.
Foreign media double-labeled the wreckage of Chinese and American rockets
China's Long March 5B rocket was successfully launched this time, the core module successfully entered orbit, and the launch mission was successfully completed. In this regard, foreign media has invented a new aerospace word "runaway rocket wreckage".
The British " Guardian " once pointed out that the Long March 5B rocket appeared "out of control" after the launch mission. The trajectory of the rocket passes through many densely populated areas, and there is the possibility of falling to the ground out of control, posing a threat to ground safety.
"The New York Post " reported on the 3rd, "Scientists have warned that the super-large space junk from China may fall into New York or a larger city." When the "Falcon 9" rocket wreckage fell on a farm in the United States, foreign media used beautiful and romantic words to package the incident as a mysterious anecdote.
"The New York Times", in the report that the "Falcon 9" wreckage fell into Washington state , once said that the rocket wreckage "lit up the night sky of Seattle ". In contrast to the Long March 5, the "New York Times" reported that the "Long March 5 rocket" violently fell back to the earth, and the public may be hit by the 23-ton rocket wreckage.
Foreign media smears experts one by one to refute rumors
Harvard University astrophysicist Jonathan McDowell once said in an interview that the probability of rocket debris causing injury or hitting a human body is very low. "Even for personal safety, I don't have any insomnia."
Chinese aerospace expert Xing Qiang responded to in response to previous smears by Western media, arguing that the trajectory of the wreckage of the Long March 5 rocket was not "out of control" as reported by foreign media.
Xing Qiang said that the entire rocket's trajectory The process of falling is all calculated in advance and combined with the passivation technology of the rocket, which not only shortens the orbital time of the rocket wreckage, but also ensures that the wreckage does not pose a threat to the safety of the earth.
Hong Kong military expert Liang Guoliang also once In an interview with the media on the 5th, he said that what is currently in orbit is some of the remaining wreckage after the rocket has completed its delivery mission, and it is not the "rocket out of control" that foreign media refers to. Under such circumstance, the foreign media's such reports are confusing. To take a step back, the rocket itself has completed the delivery mission, and the wreckage itself is space junk, which does not need to be further controlled, so there is no such thing as "out of control".
Diplomacy Ministry response: extremely low hazard
Chinese experts have responded to foreign media reports of "out-of-control rocket wreckage" many times. After completing the delivery mission of the core compartment, the rocket wreck lost its power and its structure Damage may have already occurred, so the rocket wreckage (no matter which country) does not yet have the concept of so-called "controllable".
Chinese Foreign Ministry spokesman Wang Wenbin responded on the 7th, the current international practice, It is the ablation and destruction of the last stage of the rocket when it re-enters the atmosphere. The Chinese side has always been committed to the peaceful use of outer space and strives to maintain the security of outer space.
The Long March 5 rocket uses a special technology to design , and most of the components will be reused In the process of entering the atmosphere, it is ablated and destroyed, and the harm to the current aviation activities and human body is extremely low.
Wang Wenbin emphasized that China has always been closely following the re-entry of the rocket's final stage into the atmosphere. At present, the relevant competent authorities are responsible for monitoring the operation of the rocket, and the information will be communicated to the public in a timely manner.
