A single-stage to orbit (or SSTO) vehicle would be a vehicle that could reach orbital velocity without the use of multiple stages. The main problem in constructing such a vehicle is to make the engine efficient and the vehicle structure lightweight enough, to make it unnecessary to drop away parts of the vehicle, whilst still delivering a reasonable payload to orbit. It is believed by some that reusable vehicles, particularly SSTO reusable vehicles, would lead to much reduced costs for access to space and allow aircraft-like operations.

abstract	A single-stage to orbit (or SSTO) vehicle would be a vehicle that could reach orbital velocity without the use of multiple stages. The main problem in constructing such a vehicle is to make the engine efficient and the vehicle structure lightweight enough, to make it unnecessary to drop away parts of the vehicle, whilst still delivering a reasonable payload to orbit. It is believed by some that reusable vehicles, particularly SSTO reusable vehicles, would lead to much reduced costs for access to space and allow aircraft-like operations. No actual SSTO launch vehicles have been constructed - current orbital launches are either performed by multi-stage fully expendable rockets, or like the Space Shuttle which is multi-stage and partially reusable, since it is assisted by a drop tank and solid rocket boosters that are jettisoned during the climb. Several research spacecraft have been designed and constructed, most notably the DC-X, the X-33, and the Roton SSTO; but none of them have been anywhere near an orbital launch. So far, SSTOs have been unsuccessful due to technical and/or economic difficulties.
