What would it be like to watch Earth fade into the distance? If we're ever going to send humans to Mars and beyond, they're going to have to deal with seeing the Earth get smaller and smaller until it's just another light in the sky, and psychologists aren't sure how people are going to handle it.
It's been dubbed the "Earth-out-of-view phenomenon." In the history of space travel, no one has ever been far enough from home to experience it. The moon is as far as anyone's ever gone, and from there, Earth still looks like Earth, with all its clouds, oceans and continents spinning around.
