Astronauts often comment on the thinness of the Earth’s life-supporting envelope, and how it suggests the fragility of our planetary ecosystem. They also note that the number of atmospheric layers they can detect with their eyes is much greater than what their photographs show.

One of the earliest known implications of space travel noticed by returned astronauts is what author Frank White has called the “overview effect.”

“For the first time in my life, I saw the horizon as a curved line. It was accentuated by a thin seam of dark blue light: the atmosphere,” said Ulf Merbold, a German astronaut who flew on Space Shuttle Columbia in 1983. “This was not the ‘ocean’ of air I had been told it was. … I was terrified by its fragile appearance.”

White has made the overview effect a life philosophy. He’s helped found the Overview Institute, an organization dedicated to immersive space-related art and media that will allow the rest of us Earth-bound landlubbers to experience the transcendent insights that, until now, has been possibly only by space travel...

Astronaut Gerst: Some things that on Earth we see in the news every day and thus almost tend to accept as a “given”, appear very different from our perspective. We do not see any borders from space. We just see a unique planet with a thin, fragile atmosphere, suspended in a vast and hostile darkness. From up here it is crystal clear that on Earth we are one humanity.
