AI overview
A rocket engine is a type of jet engine that doesn't need to breathe air and is designed to propel missiles or vehicles through space or the atmosphere. It matters because it enables spacecraft, satellites, and other vehicles to travel where air-breathing engines cannot operate, such as in the vacuum of space.
