Short description : none
Major contributors to space debris include the explosion of upper stages and satellite collisions.[ 1]
Overview
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[update] 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]
