In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft. For spacecraft far from Earth (for example those in orbits around the Sun)^{[clarification needed]} an orbital maneuver is called a deep-space maneuver (DSM).^[1]

When a spacecraft is not conducting a maneuver, especially in a transfer orbit, it is said to be coasting.
