One in a Billion by Don Pettit
"I float in the cupola, looking out the seven windows composing this faceted transparent jewel. While my mind is submerged in contemplation, my eyes gorge on the dim reflections from a night-time Earth. There are more than 8 billion people who call this planet home. There are seven of us who can say the same for the space station. What a privilege it is to be here."
