As we reflect back upon the tragic loss of Challenger and her brave crew of heroes who were aboard that fateful day, I am reminded that they truly represented the best of us, as they climbed aloft on a plume of propellant gasses, reaching for the stars, to inspire us who were Earthbound.
When I was a little kid, I was really scared of the dark. But then I came to understand, dark just means the absence of photons in the visible wavelength—400 to 700 nanometers. Then I thought, well it’s really silly to be afraid of a lack of photons. Then I wasn’t afraid of the dark anymore after that.
