Book Review: The Orbital Perspective, SpaceRef
"Ron Garan used to be an astronaut. Now he helps people in remote African communities obtain fresh drinking water. Yet he still has his head back amongst the stars. How he came to this point is the subject of his book "The Orbital Perspective". While many people who have spent time in space have come back with altered perceptions and equipped with a new perspective of our home planet, few manage to express that change in perspective as well as Garan does. Moreover, even fewer actually take that enhanced perspective and put it into action - again, as Garan does."
