An illustration depicts space junk surrounding the Earth, consisting of abandoned satellites, satellite fragments, astronaut tools, and other debris floating in orbit. While air travel safety is a current concern, it remains a safe mode of transportation. Statistics from the International Air Transport Association show a decreasing rate of accidents per flight over the years.
However, space junk poses a significant threat to aviation safety. Researchers from the University of British Columbia have highlighted the increasing risk of space debris colliding with aircraft, with potential catastrophic consequences. They found that major airports face a 0.8% annual risk of debris in high-density airspace, which rises to 26% in busy regions like the northeastern United States and northern Europe.
The closure of airspace due to space debris, as seen in a recent incident involving a 20-ton rocket, can lead to significant disruptions and economic strain. With the growing number of daily flights and objects in orbit, the risk of debris damaging aircraft has escalated. Even small debris pieces can cause severe damage, emphasizing the urgent need for solutions.
The researchers suggest that all space missions should ensure controlled reentry into the ocean to mitigate the risk of uncontrolled debris collisions with aircraft, instead of halting space activities or grounding flights.
“Researchers recommend conducting controlled reentries for rocket bodies, guiding them to remote ocean areas far from people and aircraft. Currently, less than 35 percent of launches implement controlled reentries. The authors argue that universal use of controlled reentries would reduce risks substantially. They stress the importance of policy and legal changes to prevent accidents and avoid disruptions caused by sudden airspace closures. Read the full article on Travel & Leisure.”
