Inspired by fireworks, our ancestors invested rockets. The ignition of rockets (including the carrier rocket which is responsible for carrying a satellite into space) is conducted by a special starting device. The operating principle is to light with electricity the propellant of the engine in a rocket, putting the engine in a working condition so as to product thrust, and push it into space. At the order for ignition from a commander, the multistage rocket which carries a communication satellite starts soaring up into the sky, the whole Earth being shaken.
