Crew members of the fateful Challenger mission STS-51L stand in the White Room at Pad 39B following the end of the Terminal Countdown Demonstration Test (TCDT). From left to right they are: Teacher in Space Participant, Sharon "Christa" McAuliffe, Payload Specialist, Gregory Jarvis, Mission Specialist, Judy Resnik, Commander Dick Scobee Mission Specialist, Ronald McNair, Pilot, Michael Smith and Mission Specialist, Ellison Onizuka.

All would perish in the explosion shortly after launch on January 28, 1986. The world would never be the same after this disaster.
