The SSP study has been conducted in two distinct phases as shown in Figure 1-1. Phase I consisted of teainformation, assessments of past studies, definition of top-level architectures and options, assessment of the market characteristics, and preliminary identification of promising, innovative technologies and approaches. The main product of this phase was the identification of four satellite concepts in seven architecture families for additional examination during the second phase of the study. A brief summary of the Phase I efforts and acomplishments is provided below. Phase II of the study focused on those concepts and architectures selected in Phase I to further refine the concept definitions, estimate the associated life cycle costs, perform economic analyses of various options and define preliminary technology roadmaps. The results of those efforts are documented in this final study report, along with implications and conclusions drawn from those results. Management of both study efforts has been provided by the Advanced Space Analysis Office (ASAO) at NASA Lewis Research Center (LeRC), the lead center for the study.
