A status report on advanced manned launch system (AMLS) conceptual studies being conducted at the NASA Langley Research Center is presented. The primary goal of these studies is identifying means for lowering the cost of manned access to space while fulfilling mission needs. Attention is focused on partially and fully reusable launch concepts that employ an operations-oriented design approach. Identified in particular are vehicle systems, technologies, and operations factors which influence launch costs, mission, success, and safety
