Habitable Worlds Observatory telescope mirror assembly and structure technology sub-working group: first year status

As part of the Decadal recommended Great Observatories Maturation Process (GOMaP) NASA has setup Working Groups and Sub-Working Groups to assess technology gaps and define technology development roadmaps for the potential Habitable Worlds Observatory. The Telescope Mirror Assembly and Structure Technology Sub-Working Group is analyzing technology to enable a large (6-m class) telescope with dynamic and thermal ultra-stable wavefront. The sub-group’s charter includes everything from material properties to sub-systems. Mirror assembly (primary and secondary) includes: material properties, substrate geometry, mounting and mechanisms, thermal sense and control, backplane structure, and secondary mirror support structure. Paper will review first year progress including technology gap assessment and draft TRL-5 technology roadmaps.
