The primary mirror for NASA's Nancy Grace Roman Space Telescope has passed its final inspection. On May 20 and 21, engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., confirmed that no specks fell onto the mirrors during testing and that there are no defects in the coating or alignment. With this milestone complete, the primary mirror is ready for its next view: space.
