The rocket is a reaction-propulsion device that carries all of its propellants internally. It has been around for over a millennium since its invention in China around the year 1000. The 1900s saw a technological explosion of new rocket-propulsion systems, using both solid and liquid propellants. Within a couple of decades, rockets and missiles had begun to alter the course of the twentieth-century—and beyond.
