Thirty years ago today, the space shuttle Challenger exploded after launching from the Kennedy Space Center in Florida, in an event that was watched the world over. The disaster killed seven crew members including Christa McAuliffe, who hoped to be the first teacher in space. Photojournalists captured the many shocked and heartbreaking reactions of those at NASA and the spectators in the stands near the launch site.
One truly memorable and tragic photo captured by Jim Cole of The Associated Press shows McAuliffe's mother, father and sister reacting after the launch and before the deadly explosion.
Other images from around the nation show classrooms that were watching the launch. Concord, New Hampshire, McAuliffe's hometown, can be seen in these images honoring her memory after the explosion.

CORRECTION: A previous Associated Press caption misidentified a photo of McAuliffe's family reacting to the liftoff as a reaction to the explosion.
