Scientific paper

This paper examines the results of a previous assessment of earth-to-orbit (ETO) transportation technologies in the light of the requirements for larger launch vehicles for the Space Exploration Initiative (SEI). Conclusions and recommendations are listed which demonstrate that infrastructure and launch vehicles are required on the east and west coasts of the U.S. for 20,000-lb class transportation. The Space Transportation Main Engine and the Space Shuttle Main Engine are shown to be key elements, and technological advances are required in the area of strap-on high-thrust hybrid motors. An approach is outlined for defining the requirements of large launch vehicles that emphasizes simplifications of payloads and orbital assembly requirements. Launch-vehicle requirements for various SEI moon and Mars mission scenarios are discussed, and a large range of possibilities is defined.
