Critical Orbital Threat
Earth's Fragile Skies: 100 Million Pieces of Space Debris Threaten Our Future
Explore the CrisisWhat is Space Debris?
Space debris—also known as orbital debris, space junk, or space waste—refers to any non-functional, human-made object in Earth's orbit. This includes defunct satellites, spent rocket stages, fragments from collisions or explosions, discarded mission equipment, and even tiny paint flecks. These objects no longer serve any useful purpose and pose collision risks to operational spacecraft, satellites, and the International Space Station.
In summary: Space debris is any human-made object in Earth orbit that no longer serves a function and increases the risk of damage to active space operations.
Large Debris
>10 cm
~50,000 objects
Mission-killing
Medium Debris
1-10 cm
~1 million objects
Catastrophic damage
Small Debris
1mm-1cm
~100 million objects
Cumulative damage
A 1cm fragment carries the energy of a hand grenade and can cripple a satellite in milliseconds

Emerging RiskNew mega-constellations adding thousands of satellites
The Kessler Syndrome: A Tipping Point
What is Kessler Syndrome?
A cascading collision scenario where debris creates more debris, leading to exponential growth that makes certain orbital regions unusable for generations.
Current collision frequency
1 every 5-9 years
Projected growth by 2070
Population doubles
