NASA's Roman Space Telescope Clears Final Mirror Check, Heads to Launch
TL;DR Summary
NASA’s Goddard Space Flight Center completed the final inspection of the Nancy Grace Roman Space Telescope’s 2.4-meter primary mirror, confirming no specks, proper coating, and alignment. The ultralow-expansion glass mirror is silver-coated for near-infrared light and is exceptionally smooth; it will be shipped to Kennedy Space Center for an early-September launch, with the sunshade hood deployed and the aperture cover stowed for launch preparations.
