Abstract

UVO to Far-IR (UVO-FIR) mirror technology development project is a multiyear effort initiated in Fiscal Year (FY) 2022 to mature the Technology Readiness Level (TRL) of critical technologies required to enable ultra-stable telescope of the Habitable Worlds Observatory (HWO) mission. Accomplishments of 2022/23 include: building and correlating a new ‘as-built’ model of the 1.5-m ULE® AMTD-2 mirror, and extrapolating implications for achieving an ultra-stable wavefront for coronagraphy; implementing absolute gravity-sag characterization algorithms and demonstrating ability to compensate G-say via a CGH; using tailored stiffness process to design a mirror for a balloon mission whose only significant gravity sag as a function of elevation angle is coma (which can be eliminated via adjusting the secondary mirror); and as a community service, MSFC’s Center for Mirror System Characterization and Acceptance Testing (CfMSCAT) cryo-tested 7 different mirror technologies provided by industrial partners.
