The Big Picture - Challenger disaster: remembered

On January 28, 1986, at 11:38 a.m., EST, the space shuttle Challenger lifted off Pad 39B at Kennedy Space Center, Florida. The entire crew of seven was lost in the explosion 73 seconds into the launch. Today, on the 25th anniversary of this national tragedy, we honor in memory the brave crew who gave their lives for the exploration of space. Sharon Christa McAuliffe, a New Hampshire social studies teacher, was NASA’s choice for the first teacher in space. Because McAuliffe was our local astronaut, she is featured heavily in this post, but we honor all seven on the anniversary of a nation’s great loss. — Paula Nelson (34 photos total)
