Key Takeaways:
- Chinese rocket engineers failed to add a way to guide the rocket spent core booster.
- Aerospace says the risk to a person of getting hit by a falling rocket debris is six per 10trn.
LAGOS (CoinChapter.com) — A Chinese space rocket booster earlier reported to make a chaotic return to Earth has plunged into the Pacific Ocean on Friday, according to the United States Space Command.
The US space command via a tweet revealed that the booster was a large piece of the Long March 5B rocket that launched a third and final module to complete the Tiangong space station.
Notably, the 23-ton hunk of Chinese space junk following its successful deployment has been orbiting for the past few days. However, atmospheric drag has been pulling the rocket body back to Earth little by little. And once again, that created some nervous sky-watching around the world.
This will be the fourth time China is allowing its rocket part to re-enter Earth’s atmosphere without having any control over where it falls. Chinese rocket designers without proper precaution allow rocket parts to come crashing down to earth, scattering tons of metal pieces across the surface.
For example, most private space companies or agencies designed their orbital rockets to return into the ocean or over unpopulated land. Interestingly, SpaceX design their rockets to make landfall autonomously to land where they can be reused.
However, this is not the case for Chinese rocket designers. China’s scientists have failed to design their rocket booster properly so as to allow it to steer itself down. Hence, the boosters use atmospheric drag to chaotically do the work and make landfall sometimes dangerously.

Recall that three of the core stages from Long March 5B launches have fallen to Earth in an uncontrolled manner. Notably, the first launch of the rocket in 2020, the booster made an uncontrolled re-entry over West Africa. Large metal debris made landfall on a village in Ivory Coast causing chaos and fear among residents.
Furthermore, in July after the third launch, another uncontrolled re-entry occurred over Southeast Asia. Once again large chunks of metal landed near populated in Malaysia. Although no one has been injured, the proximity illustrated the dangers this uncontrolled launch poses to human lives and property.
Experts Criticize Chinese Rockets Uncontrolled Return To Earth
Ted Muelhaupt, a consultant for the Aerospace Corporation, has condemned China’s use of the Long March 5B rocket. He argued that the Chinese government and scientists have to ensure that their rockets don’t pose a risk to people and infrastructures.
However, Zhao Lijian, a foreign ministry spokesman, on Friday rejected the notion that China’s handling of the Long March 5B rockets represented anything unusual. He stated that the Long March 5B had been designed to pose less danger upon re-entry.
“I would like to stress that China has always carried out activities in the peaceful use of outer space in accordance with international law and international practice. Re-entry of the last stage of a rocket is an international practice.”
Zhao Lijian said.
Meanwhile, the China Manned Space Agency issued a location warning in the final hours before the booster crashed. They provided the altitude of the perigee and apogee of the core’s decaying orbit of the projectile.
It is also worth noting that the Long March 5B booster is not the only human-made object to ever fall from space. A small piece of a SpaceX vehicle recently turned up on an Australian sheep farm in August. Additionally, pieces of spacecraft from countries, including the United States, have also fallen back to Earth recently.
What Are The Odds Of Getting Hit By Falling Rocket Part?
The Chinese uncontrolled manner of launching rockets has posed the question of the odds that someone might get struck by falling rocket debris. However, the Aerospace team has noted that the risk to a person of getting hit is six per 10 trillion.
Although where you live also matters. Because of the orientation of the orbit, nearly everyone on Earth would survive. Meulhaupt also stated that “You’re 80,000 times more likely to get hit by lightning. So you don’t need to worry about it.”
Earth would survive unscathed at 99.5 percent. But the 0.5 percent possibility that someone could have been injured or killed is high enough. So, the world has to watch and prepare and take precautionary steps”
Muelhaupt said.
