A memorial wreath stands before the Space Mirror Memorial at the Kennedy Space Center Visitor Complex during NASA's annual Day of Remembrance ceremony on Feb. 7, 2019. The memorial, a 42-foot-high by 50-foot-wide granite monument, displays the names of the fallen astronauts from Apollo 1, space shuttles Challenger and Columbia, as well as others who have lost their lives while on NASA missions or in training. Each year, Kennedy employees and guests gather with others throughout NASA to honor those astronauts who have fallen in the pursuit of space exploration.
