Kessler syndrome - Wikipedia

The Kessler syndrome (also called the Kessler effect , [1] [2] collisional cascading , or ablation cascade ), proposed by NASA scientist Donald J. Kessler in 1978, is a theoretical scenario in which the density of objects in low Earth orbit (LEO) due to space pollution is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions. [3] One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations. [3]
