Space debris

  • Space debris (also known as space junk, space pollution, space waste, space trash, or space garbage) is defunct artificial objects in space—principally in Earth orbit—which no longer serve a useful function.
  • The LEO environment is becoming congested with space debris because of the frequency of object launches. [leftover of satellite waste]
  • This has caused growing concern in recent years, since collisions at orbital velocities can easily be dangerous, and even deadly.
  • Collisions can produce even more space debris in the process, creating a domino effect, something known as Kessler syndrome.

Initiatives taken to tackle the problem

  • Inter-Agency Space Debris Coordination Committee
  • NORAD: North American Aerospace Defense Command, is an initiative of the U.S. and Canada
  • ClearSpace-1 Mission: To be launched in 2025.
  • ELSA-d, Mission: ELSA-d (End-of-Life Services b)
  • Starship: Space X Starship
  • NEO-01: China
  • Project NETRA: ISRO
