Human history becomes more and more a race between education and catastrophe.

Space Shuttle Challenger Disaster

The Space Shuttle Challenger disaster occurred on January 28, 1986, when Space Shuttle Challenger (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members.

The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida at 11:38 EST (16:38 UTC). Disintegration of the vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. This led to the separation of the right-hand SRBs aft attachment and the structural failure of the external tank. Aerodynamic forces broke up the orbiter.

The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. The exact timing of the death of the crew is unknown; several crew members are known to have survived the initial breakup of the spacecraft. The shuttle had no escape system, and the impact of the crew compartment with the ocean surface was too violent to be survivable.

Oh! I have slipped the surly bonds of Earth

And danced the skies on laughter-silvered wings;

Sunward I’ve climbed, and joined the tumbling mirth of sun-split clouds, — and done a hundred things

You have not dreamed of — wheeled and soared and swung

High in the sunlit silence. Hov’ring there,

I’ve chased the shouting wind along, and flung

My eager craft through footless halls of air….

Up, up the long, delirious, burning blue

I’ve topped the wind-swept heights with easy grace.

Where never lark, or even eagle flew —

And, while with silent, lifting mind I’ve trod

The high untrespassed sanctity of space,

Put out my hand, and touched the face of God.
