Urgent Need for Space Debris Management
The increasing amount of space debris poses a significant risk to both satellites and human safety on Earth. With plans for launching approximately 60,000 new satellites in the coming years, the situation is anticipated to worsen, leading to more orbital congestion and increased chances of dangerous collisions. A vivid example shared involved a Canadian farmer who discovered large pieces of SpaceX debris on his property, highlighting how these fragments can actually pose a physical threat. Current statistics indicate there are around 12,400 tons of space junk, of which 130 million tiny fragments are moving at extremely high velocities, amplifying concerns regarding space sustainability.
