Traveling to space, it turns out, is good for the soul. Individuals who see Earth from space, as "an oasis against the backdrop of Infinity," feel a "breaking down of boundaries and a sense of the interconnectedness and preciousness of the Earth and all those who live on it."
This phenomenon has been studied in a laboratory setting, and subjects who have experienced true awe have been observed to be "more patient, less materialistic, and more willing to volunteer to help others."
After all, as NASA astronaut Ron Garan once argued, "if you came across a vibrant oasis in an inhospitable desert, you wouldn't trash it. You'd take care of it!" So how can we gain this type of experience in our lives? Very few of us get to go to space. Until we do, we will have to live vicariously through our robot emissaries.
