National Cathedral’s Space Window containing lunar material

The Washington National Cathedral features a stained-glass 'Space Window' that incorporates a small fragment of lunar rock from the Apollo 11 mission embedded within the glass. The lunar fragment was provided to the cathedral by NASA and is set near the center of the window as a symbolic connection between human exploration and spiritual reflection. The window is a unique example of a religious building incorporating extraterrestrial material into its fabric. The cathedral interprets the window as part of its broader program of modern stained-glass commissions.
