Who were the people who died on the challenger?

The Space Shuttle Challenger disaster on January 28, 1986, resulted in the tragic deaths of seven crew members. They were Francis R. Scobee, Michael J. Smith, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis, and Christa McAuliffe, who was a teacher and the first civilian selected to fly in space. The accident occurred just 73 seconds after liftoff due to the failure of an O-ring seal in the solid rocket booster. This incident profoundly impacted NASA and led to significant changes in safety protocols and practices.
