Families of the astronauts lost in the space shuttle Challenger accident gathered at the Kennedy Space Center on Thursday to mark 40 years since the tragedy. All seven crew members were killed when Challenger broke apart 73 seconds after liftoff on 28 January 1986.
The accident was caused by the failure of O-ring seals in the right solid rocket booster, weakened by the cold weather. Officials also acknowledged a dysfunctional culture at NASA that contributed to the disaster and later to the 2003 Columbia shuttle loss.
Among the crew was schoolteacher Christa McAuliffe, selected from over 100 candidates. Two fellow teacher-in-space contenders, Bob Veilleux and Bob Foerster, attended the memorial. Foerster expressed gratitude that space education thrived after the accident, ensuring the crew were not just remembered as martyrs.
The Space Mirror Memorial at the visitor complex now bears 25 names, including those of the Challenger seven, the Columbia seven, the Apollo 1 crew, and others lost in aviation and job-related accidents. Relatives of fallen crews from Columbia and Apollo also joined the ceremony.
Speaking at the event, Lowell Grissom, brother of Apollo 1 commander Gus Grissom, reflected on the lost potential: “You always wonder what they could have accomplished.” NASA's Day of Remembrance also included ceremonies at Arlington National Cemetery and the Johnson Space Center.
