Evelyn Husband-Thompson, widow of shuttle commander Rick Husband on mission STS-107, and her children place flowers at the memorial dedicated to the seven crew members of Columbia who were lost as they returned from the mission. Husband-Thompson participated in the special event held to honor NASA's fallen heroes in front of the Space Mirror Memorial at NASA's Kennedy Space Center Visitor Complex. Kennedy marked the NASA Day of Remembrance with special ceremonies. This year the crew of Columbia was remembered in a special way on the day that marked the fifth anniversary of the Columbia accident. Photo credit: NASA/Kim Shiflett
