The overview effect

...It was always part of NASA’s mission to look inward, not just outward. The National Aeronautics and Space Act of 1958, which established the agency, claimed as its first objective “the expansion of human knowledge of phenomena in the atmosphere and space.” nasa’s early weather satellites were followed, in the seventies and eighties, by a slew of more advanced instruments, which supplied data on the ozone layer, crops and vegetation, and even insect infestations. They allowed scientists to recognize and measure the symptoms of climate change, and their decades’ worth of data helped the Intergovernmental Panel on Climate Change conclude, in 2007, that global warming is “very likely” anthropogenic. According to a report released last month by nasa’s inspector general, the agency’s Earth Science Division helps commercial, government, and military organizations around the world locate areas at risk for storm-related flooding, predict malaria outbreaks, develop wildfire models, assess air quality, identify remote volcanoes whose toxic emissions contribute to acid rain, and determine the precise length of a day.

These seem like key functions of civilization as we know it...

...We seem to need to see the planet as a whole in order to think about it as such.

Generations of astronauts, after looking at Earth from space, have professed a profound new understanding of it. Edgar Mitchell, who, in 1971, became the sixth man to walk on the moon, said, “From out there . . . international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch.’ ” Michael Collins, Neil Armstrong’s crewmate on Apollo 11, expressed similar sentiments in his memoir, “Carrying the Fire,” which was published in the midst of the Cold War. Seeing our home planet from afar, he wrote, prompted an epiphany: “The earth must become as it appears: blue and white, not capitalist or Communist; blue and white, not rich or poor; blue and white, not envious or envied.”

Mike Massimino, in his memoir, “Spaceman,” reports having spent almost a full day staring out a window of the Space Shuttle Columbia, watching sunrises and lightning storms (“like a form of communication, like a sequence, like the clouds are alien creatures speaking to each other in code”). On his second spacewalk, Massimino told me recently, he had a spare moment to “take in the view.” He recalls being struck not only by Earth’s incredible beauty—“We are living in a paradise”—but also by its fragility. From out there, he said, especially during night passes, “you can see the thinness of the atmosphere,” a bluish-green line. This sudden perception of Earth as a delicate, intricate system is so common among astronauts that the writer Frank White coined a term for it: the overview effect...
