What is space debris?

Space debris refers to the defunct satellites, spent rocket stages, and other remnants left in orbit around the Earth as a result of human space exploration activities.

The growing problem of space debris

The accumulation of space debris in Earth’s orbit poses a significant threat to satellites, spacecraft, and even astronauts, as even small debris can cause severe damage upon collision.

Active debris removal

Active debris removal involves technologies and strategies aimed at actively capturing and removing space debris from orbit, thus reducing the risk of collisions.

Laser-based debris removal

Laser-based debris removal is a proposed method where lasers are used to target and vaporize small debris, causing them to lose momentum and eventually fall back into Earth’s atmosphere.

The use of nets

One approach to space debris capture involves launching nets that can ensnare larger pieces of debris, allowing for controlled re-entry into Earth’s atmosphere.

Sovereign capabilities in space debris remediation

Various countries are developing their own space debris remediation capabilities, including robotic systems that can autonomously capture and deorbit debris.
