It’s not unusual for rocket parts to fail to safely deorbit. We’re really fortunate in the sense that it doesn’t appear to have hurt anybody.” “It flew over population centers and it reentered Earth’s atmosphere. “It was seemingly a successful launch, until we started getting information about a reentry of a rocket body, a reentry that was really dangerous,” said Jim Bridenstine, who was NASA’s administrator at the time, according to Jeff Foust of SpaceNews. Debris from its wild reentry was reportedly scattered across villages in Cote d’Ivoire luckily, there were no accounts of injuries or fatalities caused by the impacts. Ground-based radar trackers have revealed that the 30-meter-tall CZ-5B core is tumbling in space, confirming that Chinese space officials do not have control over the component and therefore cannot perform a deorbit burn that would ensure a safe reentry.Ĭhina already sparked worldwide criticism when it initially debuted the CZ-5B in May 2020, a launch that also placed the core booster into an uncontrolled orbit. 'On the issue of uncontrolled rocket body reentries, the states of the Global South hold the moral high ground: their citizens are bearing most of the risks, and unnecessarily so, since the technologies and mission designs needed to prevent casualties exist already.Expendable rocket parts that enter orbit are often equipped to perform “deorbit burns,” maneuvers that guide them into controlled reentries of the atmosphere over unpopulated regions. 'Launch providers have access to technologies and mission designs today that could eliminate the need for most uncontrolled re-entries,' they said. NASA administrator Bill Nelson said that China was 'failing to meet responsible standards regarding their space debris.' However, China doesn't agree, and in response to the 2021 Indian Ocean debris incident, the Chinese foreign ministry said that the likelihood of damage was 'extremely low.'Īccording to the authors of the Nature Astronomy paper, these risks are preventable. In the wake of this predicted uncontrolled debris fall from the Long March 5B, a similar event last year where a Chinese rocket core stage fell into the Indian Ocean, and another in 2020 where debris including a 40-foot pipe fell onto two villages in the Ivory Coast and damaged several buildings, NASA has called out China's risk management. Rockets can be designed to be actively deorbited, so that they can land in a specific area where there is no chance of injury or damage to property.

However, due to the increase in space junk in Earth's orbit, the chances of pieces of debris falling from the sky is increasing, especially in the Global South, according to research published in the journal Nature Astronomy. The chances of the debris hitting an inhabited area are very low: NASA has estimated that the odds of a person being hit by a piece of space debris are around 1 in 3,200. Once we know the precise measurements and angle of the rocket's orbit, we should be able to more accurately predict when and where the debris will fall, according to tweets by McDowell. The speed of the process of orbital decay also depends on the size and density of the objects. The location of the landings is very hard to predict, especially at the moment, as solar activity has caused atmospheric fluctuations that complicate the modeling of the flight path. 'It is always difficult to assess the amount of surviving mass and number of fragments without knowing the design of the object, but a reasonable 'rule-of-thumb' is about 20-40 percent of the original dry mass,' Holger Krag, head of the Space Safety Program Office for the European Space Agency, told SpaceNews. The larger the spacecraft, the larger the number of chunks of space debris falling back into the atmosphere, especially those made of heat-resistant materials. Orbital epoch of ~1200 UTC confirms that the inert 21t rocket core stage remains in orbit and was not actively deorbited.- Jonathan McDowell July 24, 2022
