Initially, the term space debris referred to the natural debris found in the solar system: asteroids, comets, and meteoroids. However, with the 1979 beginning of the NASA Orbital Debris Program,[1] the term also refers to the debris (alt. space waste or space garbage) from the mass of defunct, artificially created objects in space, especially Earth orbit. These include old satellites and spent rocket stages, as well as the fragments from their disintegration and collisions.
As of December 2016, five satellite collisionshave generated space debris.[citation needed]Space debris is also known as orbital debris, space junk, space waste, space trash, space litter or space garbage.[2]
As of 5 July 2016, the United States Strategic Command tracked a total of 17,852 artificial objects in orbit above the Earth,[3] including 1,419 operational satellites.[4] However, these are just objects large enough to be tracked. As of July 2013, more than 170 million bits of debris smaller than 1 cm (0.4 in), about 670,000 pieces of debris 1–10 cm, and around 29,000 larger pieces were estimated to be in orbit around the earth.[5] Collisions with debris have become a hazard to spacecraft; they cause damage akin to sandblasting, especially to solar panels and optics like telescopes or star trackers that cannot be covered with a ballistic Whipple shield (unless it is transparent).[6
