Quote of the Day
October 2, 2009
“The atmosphere on edge presents a striking sight. You see many distinct layers, all a different shade of iridescent blue. Through binoculars, I have counted six. The most amazing aspect of this view is how thin this life-preserving blanket is when compared to the full extent of the planet. Like an orbital eggshell, our atmosphere looks so frail that it might crack and be gone in an instant, rendering earth as barren and lifeless as any other baked hunk of rock orbiting the sun.”
–Don Pettit, Science Officer, International Space Station, 2002-2003
