Presentation #102.01 in the session Community & Profession.
The OTA for the Nancy Grace Roman Space Telescope includes the primary mirror, secondary mirror, and aft optics for guiding light into the Wide Field Instrument and the Coronagraph Instrument. The telescope is taking shape integrating the tested optical mirror assemblies. The assemblies have been thermal cycled to the cold temperatures for infrared operation, load tested to launch loads, vibration tested, and optically tested. Pictures and descriptions of the integration and test progress are provided, along with performance results measured at these levels of assemblies with predictions for system-level performance.
