Under rainy skies, Kennedy Space Center Director Bob Cabana speaks to guests after placing a wreath in front of the Space Mirror Memorial at the spaceport's Visitor Complex during NASA's Day of Remembrance. The brief ceremony honored the astronauts of Apollo 1, who were lost in 1967, the shuttle Challenger crew, who perished in 1986, the space shuttle Columbia astronauts who were lost in 2003, as well as other astronauts who gave their lives while furthering the cause of exploration and discovery.

Dedicated in 1991, the names of fallen astronauts are emblazoned the monument's 4.5-foot-high-by-50-foot-wide polished black granite surface which reflects the sky and has been designated by Congress as a National Memorial. Photo credit: NASA/Dimitri Gerondidakis
