"Remembering the Space Shuttle Challenger Disaster 38 Years Later"

Sunday marks the 38th anniversary of the Challenger space shuttle explosion, a disaster that killed seven people 73 seconds after launch due to an O-ring failure blamed on cold weather. The incident resulted in a 32-month suspension of NASA's shuttle program and the creation of the Rogers Commission to examine what went wrong. The crew members, including teacher Christa McAuliffe, were remembered for their sacrifice, and a commemorative coin act was passed to honor McAuliffe's memory.
