Summary
NASA completed its final inspection of the Nancy Grace Roman Space Telescope’s primary mirror on May 20, clearing the observatory for shipment to Kennedy Space Center ahead of a launch as early as Aug. 30.
Engineers checked the 7.9-foot mirror for debris, verified its alignment and optical path, and confirmed earlier vibration testing had not shifted any components.
The mirror feeds Roman’s Wide Field Instrument, and NASA said the optics passed the review "with flying colors," keeping the flagship mission on track for an early September window that could open sooner.
Roman was declared complete in April and is designed to make highly sensitive wide-field observations across the cosmos, making mirror precision central to the mission’s science goals.
