Former astronaut John Young addresses guests and attendees at a ceremony at the KSC Visitor Complex held in remembrance of the astronauts lost in the Apollo 1 fire: Virgil "Gus" Grissom, Edward H. White II and Roger B. Chaffee. Members of their families, along with Associate Administrator for Space Operations William Gerstenmaier, President of the Astronauts Memorial Foundation Stephen Feldman, Chairman of the Board of Directors of the Astronauts Memorial Foundation William Potter and former astronaut John Young, attended the ceremony. Behind the stage is the Space Mirror Memorial, designated as a national memorial by Congress and President George Bush in 1991 to honor fallen astronauts. Their names are emblazoned on the monument’s 42-1/2-foot-high by 50-foot-wide black granite surface as if to be projected into the heavens. Photo credit:NASA/George Shelton
