'The future doesn't belong to the fainthearted; it belongs to the brave'

Today marks the 30th anniversary of the Challenger Disaster

30 years ago today the space shuttle Challenger blasted off from NASA's Cape Canaveral base in Florida. It was an event broadcast around the world but other than several delays to the launch (mainly caused by poor weather) this was a routine space shuttle mission.

However 73 seconds after take-off an explosion led to a structural failure in the fuel tanks and the break up of the shuttle itself. It was one of the first major disasters to be captured live on television. All seven crew were killed including schoolteacher Christa McAuliffe.

Later that day, US President Ronald Regan delivered an emotional address to the nation, praising the astronaut's bravery and remarking that 'The future doesn't belong to the fainthearted; it belongs to the brave'. 

To mark the anniversary George Hook spoke to Mike Mullane who was a NASA astronaut from 1979 until 1990 about his memories of that day and how NASA recovered from the disaster. You can listen back below
