On a sunny Tuesday - for it seems so many awful things happen on a Tuesday - six astronauts and one schoolteacher attempted to pierce the sky. Instead they touched the stars.
Ask anyone who was alive at the time, and they will still remember where they were the moment they heard that the shuttle Challenger blew up just seventy-three seconds after lifting off from Cape Canaveral. The shape of that terrible explosion became burned into human consciousness like the shape of the mushroom cloud over Hiroshima.
The world mourned the lives lost, as well as mourning the loss of an idea, for although space flight had always been, and would always be a dangerous endeavor, there was a certain unspoken faith that human ingenuity, and the grace of God, would keep our ascent to the heavens safe. But the universe is nothing if not balanced. For every Apollo Thirteen, there would be a Challenger. For every miracle, a tragedy.
