Parachute cord (also paracord or 550 cord when referring to type-III paracord) is a lightweight nylon kernmantle rope originally used in the suspension lines of parachutes. This cord is useful for many other tasks and is now used as a general purpose utility cord by both military personnel and civilians. This versatile cord was even used by astronauts during the 82nd Space Shuttle mission to repair the Hubble Space Telescope.
