On this page about Two-stage-to-orbit:
A two-stage-to-orbit (TSTO or DSTO - Double/Dual-Stage-To-Orbit) launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between the more common system with more stages, such as the three-stage-to-orbit system, and a single-stage-to-orbit (SSTO) launcher, which does not exist yet.
A launch vehicle is a system used to deliver a payload from a planetary surface into space. There are several broad categories that launch vehicles fall under, including: Expendable launch system Reusable launch system Single stage to orbit Two stage to orbit See also spacecraft propulsion...
