"The story of Planetes follows the crew of the DS-12 "Toy Box" of the Space Debris Section, a unit of Technora Corporation. Debris Section's purpose is to prevent the damage or destruction of satellites, space stations and spacecraft from collision with debris (so-called "space debris") in Earth's and the Moon's orbits. They use a number of methods to dispose of the debris (mainly by burning it via atmospheric reentry or through salvage), accomplished through the use of EVA suits."
