Space Pollution
where stars shine, satellites soar, and a hidden danger lurks – the celestial clutter known as space debris.Space debris, also known as orbital debris or space junk, refers to non-functional, human-made objects in Earth’s orbit. This debris includes defunct satellites, spent rocket stages, fragments from collisions, and other discarded materials generated during space missions.
Causes Of Space Pollution
Satellite Collisions and Breakups
Accidental collisions between satellites or between satellites and debris can lead to the fragmentation of spacecraft, generating more debris in orbit.
Fragmentation of Rocket Stages
The breaking apart or exploding of spent rocket stages after launching payloads contributes significantly to space debris accumulation.
Intentional Destruction
Deliberate destruction or deactivation of satellites and other objects in orbit can create a substantial amount of debris.
Micrometeoroid Impacts
Tiny particles in space called micrometeoroids can impact satellites and create debris, especially if the objects are not adequately shielded.
Abandoned Spacecraft
Spacecraft that are no longer operational or have reached the end of their lifespan can become abandoned in orbit, adding to the space debris problem.
Lack of Space Traffic Management
Ineffective space traffic management, including the absence of clear regulations , can lead to increased risks of collisions and debris creation.
Impact's
Collision Risk
The primary concern with space debris is the risk of collisions with operational satellites, spacecraft, and the International Space Station (ISS). These collisions can damage or destroy the objects.
Fragmentation
When two pieces of space debris collide, they can create thousands of smaller fragments.
Kessler Syndrome
the density of objects in low Earth orbit (LEO) becomes so high that collisions between objects generate more debris, leading to a cascade of further collisions.
Space Sustainability
The increasing amount of space debris complicates future space missions and the sustainability of space activities. It necessitates measures to mitigate debris generation.
