Large powers have developed various capabilities for destroying satellites.Now companies are buildingadvancedservice spacecraft that could become weapons.The purpose of these service craft is to repair and move existing satellites,but all it takes is a change ofintentfor these spacecraft to become war craft.

A Chinese space weapon test which destroyed one of its owndefunctsatellites in 2007,createda great deal ofdebris （殘骸）that put other satellites in danger.If remains from one act of destruction go on to destroy further satellites,a chainreaction renderssome orbits unusable.

Kessler Syndrome

凱斯勒現(xiàn)象

Kessler Syndrome is a thought-up situation made by the NASA scientist Donald J.Kessler in which the amount of space debris in orbit is large enough to cause space collisions to happen often.This would make space mostly unusable for years if it happened at an extreme level.

There is a satellite in orbit that is large and inactive,making it count as space debris,but it is in an orbit with a large amount of space debris.Two known objects get within 200m of it every year.This could cause a lot of space debris,inducing a domino effect with more collisions.
