KENNEDY SPACE CENTER, FLA. - Family members of the STS-107 astronauts and other dignitaries attend a dedication ceremony at the Space Mirror Memorial at the Kennedy Space Center Visitor Complex. During this solemn event, the names of the STS-107 astronauts who lost their lives during the Columbia accident -- Rick Husband, Willie McCool, Laurel Clark, Michael Anderson, David Brown, Kalpana Chawla, and Ilan Ramon -- join the names of 17 other space heroes who gave their lives for the U.S. space program. The "Space Mirror," 42 1/2 feet high by 50 feet wide, illuminates the names of the fallen astronauts cut through the monument's black granite surface.
