List of space debris producing events

Summary

Major contributors to space debris include the explosion of upper stages and satellite collisions.[1]

Overview edit

There were 190 known satellite breakups between 1961 and 2006.[2] By 2015, the total had grown to 250 on-orbit fragmentation events.[3]

As of 2012 there were an estimated 500,000 pieces of debris in orbit,[4] with 300,000 pieces below 2000 km (LEO).[1] Of the total, about 20,000 are tracked.[1] Also, about sixteen old Soviet nuclear space reactors are known to have released an estimated 100,000 NaK liquid metal coolant droplets 800–900 km up,[5] which range in size from 1 – 6 cm.[5]

The greatest risk to space missions is from untracked debris between 1 and 10 cm in size.[1] Large pieces can be tracked and avoided, and impact from smaller pieces are usually survivable.[1]
