This is interesting: The Overview effect
"The overview effect is a cognitive shift in awareness reported by some astronauts and cosmonauts during spaceflight, often while viewing the Earth from orbit or from the lunar surface.
It refers to the experience of seeing firsthand the reality of the Earth in space, which is immediately understood to be a tiny, fragile ball of life, "hanging in the void", shielded and nourished by a paper-thin atmosphere. From space, national boundaries vanish, the conflicts that divide people become less important, and the need to create a planetary society with the united will to protect this "pale blue dot" becomes both obvious and imperative"
I've obviously never been into space but I can relate to that feeling.
Reminds me of something similar.. I mean the profound effects space has on people..
There's this amazing short podcast of astronaut Dave Wolf recounting his first spacewalk....he describes how the shadows are the blackest, there's no reflected light if your arm goes in tot the shadow it disappears.
200 miles above Earth's surface, astronaut Dave Wolf -- rocketing through the blackness of Earth's shadow at 5 miles a second -- floated out of the Mir Space Station on his very first spacewalk. In this short, he describes the extremes of light and dark in space, relives a heart-pounding close call, and shares one of the most tranquil moments of his life...
...Out in blackness of space, the contrast between light and dark is almost unimaginably extreme -- every 45 minutes, you plunge between absolute darkness on the night-side of Earth, and blazing light as the sun screams into view. Dave and Anatoly were tethered to the spacecraft, traveling 5 miles per second. That's 16 times faster than we travel on Earth's surface as it rotates -- so as they orbited, they experienced 16 nights and 16 days for every Earth day.
