Space Junk Explained: What's Orbiting Above Us Right Now?
Space Junk Explained: What's Orbiting Above Us Right Now?
By: Kashmik Singh Chouhan
More than 34,000 large objects and millions of tiny fragments are circling Earth at 28,000 km/h. Space junk is no longer just a sci-fi issue it's real and growing.
Space junk includes dead satellites, rocket parts, tools lost by astronauts, and debris from collisions. Even a paint fleck can cause damage at orbital speeds.
What Counts as Space Junk?
Junk builds up from satellite breakups, anti-satellite missile tests, leftover rocket boosters, and accidental explosions.
Where Does It Come From?
– 34,000+ objects >10 cm
– 900,000+ fragments 1–10 cm
– 128 million particles <1 cm
How Much Is Up There?
Debris can destroy satellites and threaten the ISS. Space agencies perform collision-avoidance maneuvers regularly.
Risks to Satellites & ISS
A chain reaction of collisions could trap us on Earth. More junk = more collisions = even more junk. This dangerous feedback loop is a top concern.
The Kessler Syndrome
Radar, telescopes, and satellites scan the skies 24/7. When needed, alerts are sent to move spacecraft out of harm's way.
How It's Tracked
Laser brooms, harpoons, drag nets, and robotic arms are being tested to clean orbit. Most are still in the early stages.
Cleanup Ideas
The UN and space agencies now require satellites to plan safe disposal. Some new tech burns up after use.
What's Being Done?
Space is not endless when it comes to orbits. Managing space debris now means safer missions, cleaner skies, and a future for space exploration.
