suicide burn noun3 •A method of soft-landing a rocket with a well-timed, high-thrust engine burn starting at the last possible second, such that it reaches a vertical speed of zero at precisely or almost precisely at the exact moment that it touches the landing pad and the engine shuts down. •An instance of such a landing.A suicide burn is a more efficient method of landing than slowly decelerating over the length of a long descent, as a smaller proportion of the engine's thrust is spent fighting against gravity. •A rocket firing during such a landing. formssuicide burns
