    Abstract(s): 

    To achieve the ambitious goal of directly imaging exo-Earths with a coronagraph, future space-based astronomical telescopes will require wavefront stability several orders of magnitude beyond 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 multi-phase, NASA-funded effort to mature key technologies to enable ultra-stable telescopes in space. 

    This talk will address Phase 1 (systems engineering) and Phase 2 (technology development) of the ULTRA program. The completed Phase 1 is a system study to evaluate potential architectures, perform trade studies, and identify technology gaps that must be addressed to enable picometer-level optical stability in space. In the current phase 2, the team will mature critical technologies identified as Phase 1 gaps through component-level hardware demonstrations.  The key outcome is to demonstrate performance of these technologies in the picometer regime and with flight-traceable properties – including active systems like segment sensing and actuation and thermal sensing and control, as well as passive systems like low distortion mirror mounts and composite structures.  Raising the TRL of these technologies will address the most difficult parts of the stability problem with the longest lead times and provide significant risk reduction for their inclusion in future mission concepts.

    Speaker Bio(s): 

    Laura Coyle is a Senior Optical Engineer at Ball Aerospace in Boulder, CO and the Principle Investigator for the Ultra-Stable Large Telescope Research and Analysis – Technology Maturation (ULTRA-TM) program.  She completed her undergraduate degree in Physics at Colgate University and her Masters and Ph.D. in Optical Sciences from the University of Arizona. At Ball Aerospace, she supports technology development for ultra-stable optical systems and other astrophysics missions. She also supports optical alignment and performance verification for NASA flight programs like the Operational Land Imager 2 and the James Webb Space Telescope and is a member of the Ball Aerospace wavefront sensing and control team responsible for on-orbit alignment and commissioning of Webb.
