Hundreds of people attended a ceremony at the Kennedy Space Center to honor the 25th anniversary of the space shuttle Challenger explosion.

On January 28, 1986 seven crew members including the first civilian teacher to make the cut boarded the Challenger in preparation for their first flight. A mere 73 seconds after takeoff the shuttle exploded, killing all seven members and touching a nation’s heart.

The crew members that lost their lives that day included Dick Scobee, commander; Michael J Smith, pilot; Ellison Onizuka, mission specialist; Judy Resnik, mission specialist; Ron McNair, mission specialist; Gregory Jarvis, payload specialist; and Christa McAuliffe, payload specialist and civilian teacher.

Scobee’s widow, June Scobee Rodgers, spoke to the crowd about looking towards the future in many ways including space travel and space and a science education.

The anniversary comes as NASA is ending the space shuttle program. There are only three remaining scheduled flights before the program comes to a close.
