The various U. S. government agencies that are pursuing in-space assembly technology have a common need to demonstrate technological capabilities on a space-based platform. Several of the agencies, and different mission developers within an agency, have independently begun planning such demonstrations. This paper reports on a study of how well the different planned platforms could support demonstrations of the agencies’ joint needs. The study first prioritized a comprehensive list of the needs for in-space assembly capabilities across the agencies against jointly agreed evaluation criteria. Each planned demonstration platform was characterized to a first order. The capability needs were qualitatively assessed against four figures of merit including their joint priority, and the platforms were assessed against five criteria to produce a quantitative weighting factor of reach capability need and each platform. A Quality Function Deployment (QFD) matrix was used to deploy the weighted capability needs against the weighted platforms capabilities. This first-order assessment showed that the platforms reflect a great deal of redundant capability without a strong reason to prefer one over the others. These results were largely insensitive to the details of the assumptions.
