Abstract

A major design trade for the Terrestrial Planet Finder is the choice between a structurally connected and a separated spacecraft interferometer architecture. Three metrics are applied to the comparison and serve to show which aspects of each architecture drive their design. The primary metric is the wet mass for which reference designs are discussed and the relevant mass drivers are examined. Capability and adaptability metrics are used to include more qualitative design comparisons, with the result being a more complete understanding of the trade-offs involved.
