This results in higher development and operational costs. Since the required kinetic energy amount is shared by two vehicles, design difficulties ease, although key technologies (such as propulsive, structural and thermal protection concepts) remain design critical. However the “orbital dry mass” of the second stage to deliver the same payload is significantly reduced compared with SSTO. Concerning aerodynamical, flight mechanical and dynamical aspects, stage integration and separation introduce an additional problem.
