NASA’s Roman Telescope Camera Beats Its Sharpness Goal by Nearly 30% After a Mirror Nudge Smaller Than a Hair
Nature World News | 21.10.2026 20:01NASA's Nancy Grace Roman Space Telescope has finished checking out its main science camera, and the result is better than its own engineers planned. After a final round of optical corrections, the Wide Field Instrument now shows an optical error of 63 nanometers RMS against a requirement of about 90 nanometers, which NASA describes as nearly 30% better than predicted, according to the Roman mission update posted by NASA's Goddard Space Flight Center.
