Paper Abstract

To meet the ambitious science goal of characterizing exo-Earths via direct imaging and spectroscopy, future space-based astronomical telescopes will have requirements for optical stability at least several orders of magnitude beyond the current state of the art. Mission concepts requiring stability on the order of picometers include the Large UV/Optical/Infrared (LUVOIR) Surveyor and the Habitable Exoplanet (HabEx) Observatory, which use large primary mirrors and internal coronagraphs to perform high contrast imaging. The Ultra-stable Large Telescope Research and Analysis (ULTRA) Program is a system study performed by an industry consortium led by Ball Aerospace to evaluate potential architectures, perform trade studies, and identify technology gaps that must be addressed to enable picometerlevel optical stability in space. This paper will describe the results of the study, including identification and prioritization of technology gaps and a development roadmap to raise the technology readiness level (TRL) of key enhancing/enabling technologies.
