This is the third time a Long March 5B booster has made an uncontrolled reentry.
The biggest spacecraft to fall uncontrolled from space
This is the third time in two years that China has disposed of its rockets in an uncontrolled manner. In the second instance, in May 2021, the rocket debris. But the first incident, in May 2020, caused metallic objects to reportedly rain down upon villages in the Ivory Coast, although there were no reported injuries.
"The general rule of thumb is that 20% to 40% of the mass of a large object will reach the ground, but the exact number depends on the design of the object," Marlon Sorge, a space debris expert at The Aerospace Corporation,"Generally, for an upper stage, we see small and medium tanks survive more or less intact, and large engine components," Sorge added."The large tanks and the skin of this core stage are likely to come apart.
"Spacefaring nations must minimize the risks to people and property on Earth of reentries of space objects and maximize transparency regarding those operations," NASA Administrator Bill Nelsonafter the 2021 Long March 5B crash landing."It is clear that China is failing to meet responsible standards regarding their space debris."
