A two-stage-to-orbit (TSTO) or two-stage rocket launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between a three-stage-to-orbit launcher and a hypothetical single-stage-to-orbit (SSTO) launcher. At liftoff the first stage is responsible for accelerating the vehicle. At some poi… WebA multistage rocket is one that uses two or more engines that ignite consecutively (one after another) to propel a rocket higher and faster. Lower and intermediate stages always use engines that have no delay or tracking smoke and no recovery system ejection charge. The absence of a delay charge allows the next engine to receive the maximum ...
