What Does SSTO Stand For?

SSTO stands for Single Stage To Orbit

SSTO, or Single Stage To Orbit, refers to a launch vehicle design that is capable of reaching Earth orbit without the need for multiple stages. This approach simplifies the rocket's structure and reduces the complexity associated with staging, thereby potentially lowering costs and increasing reliability. SSTO systems are engineered to perform all necessary flight operations, from liftoff to orbital insertion, within a single vehicle framework, making them a notable focus in advanced aerospace engineering and space exploration initiatives.
