Kessler Syndrome is a hypothetical scenario proposed by NASA scientist Donald J. Kessler in 1978 which predicts that when the density of objects in low Earth orbit (LEO)-roughly 100-1,200 miles above our planet reaches a certain critical level, it could lead to a chain reaction of collisions which could render the orbit unfit for human use and halt the space age.
