NASA Marks 25th Anniversary of the Challenger Disaster
January 28, 2011 "This year marks the 25th anniversary of the loss of the Challenger—a tragedy that caused us to completely rethink our systems and processes as we worked to make the shuttle safer," NASA Administrator Charles Bolden said.
"The nation will never forget Jan. 28, 1986, nor its indelible images," Bolden added.
Challenger's entire crew was killed when the shuttle exploded just 73 seconds after its launch, 46,000 feet in the air. The explosion was broadcast on live television.
