Challenger

Challenger Explosion
NASA: Challenger Explosion

Twenty-five years ago today my teachers had us all gather in a classroom. A teacher was being sent into orbit. The intent was for us to see a historic event. Instead we got to see even bigger history being made as the Space Shuttle exploded 73 seconds after launch. The disintegration of the vehicle was blamed on failure of the o-rings to contain the hot gases. It grounded the shuttle program.

When I attended Space Camp over a year later, the program was still grounded. One of my hopes was to better understand the cause. The adults instead steered us towards the physics of space flight and mechanics. A black spot on the history seemed to be avoided.

Years later, my eighth grade science fair project was to show how freezing o-rings, especially with water involved, distorted their shape. Some o-rings even cracked. It earned me a second place overall for the school. It also got me to the regional science fair where it did not fare so well.
