Technology plan for the Terrestrial Planet Finder coronagraph

This document details the technology plan for the first of the TPF missions, the Terrestrial Planet Finder Coronagraph (TPF-C). TPF-C is currently in the first (or pre-Phase A) stage of the NASA project life cycle, and is undertaking a suite of technology development projects to demonstrate technological readiness leading to its Mission Concept Review, currently planned for late FY2006. Contained in these pages is an overview of planned pre-Phase A technology development activities, as well as activities planned through Phase C/D.
