This is a guest essay by Frank White, who originated the Overview Effect concept and is the author of The Overview Effect: Space Exploration and Human Evolution.
The Overview Effect® is a term that describes the experiences of astronauts when they view the Earth from space and in space.
However, that is not how the phrase and the resulting theory originated. It started with a cross-country flight that I took in the mid-1980’s. As I looked down at the Earth from above, I had an epiphany. As I have described in my book, The Overview Effect: Space Exploration and Human Evolution:
“People living in space settlements will always have an overview! They will be able to see how everything is related, that what appears to be ‘the world’ to people on Earth is merely a small planet in space, and what appears to be ‘the present’ is merely a limited viewpoint to one looking from a higher level.
People who live in space will take for granted philosophical insights that have taken those on Earth thousands of years to formulate. They will start at a place we have labored to attain over several millennia.”
“That moment of realization gave birth to the term Overview Effect, which meant, at the time, that the predicted experience of astronauts and space settlers would have a different philosophical point of view as a result of having a different physical perspective. We might say today that the statement above formed the hypothesis of Overview Effect theory. I knew right away that I needed evidence for the theory, but there were no space settlers then, and there really aren’t any now, in the sense of people who have chosen to live permanently off of planet Earth.
So, I turned to interviewing astronauts as the closest possible proxies for members of future space communities.
Thus, I have been thinking and writing about the Overview Effect continually since that time, and this effort has expanded my understanding of the phenomenon enormously.” (1)
The Overview Effect was, of course, experienced by space travelers long before it had a name. Yuri Gagarin, the Soviet cosmonaut who orbited the Earth in 1961, had the experience and he said some truly Overview Effect-like things on his unprecedented flight. For example:
Orbiting Earth in the spaceship, I saw how beautiful our planet is. People, let us preserve and increase this beauty, not destroy it!
and
Looking at the earth from afar,
you realize it is too small for conflict,
and just big enough for co-operation.
Astronauts and cosmonauts echoed Gagarin’s words for more than two decades, but the phenomenon still had no name.
Thus, it was not until 1987, when the first edition of my book was published, that the term “Overview Effect” began to be used within the space community, and gain credibility.
These words have also evolved to represent a fundamental difference in how humanity views its home planet, and its future: Overview Thinking versus Surface Thinking.
Not long after Gagarin’s flight, the power of the Overview Effect revealed itself with the Apollo 8 mission.
Apollo 8 launched at a time when hopelessness dogged the minds of Earthlings. The United States had been rocked by war, assassinations, riots, and a growing suspicion that the government could not be trusted.
Yet, on Apollo’s trip to the Moon, the three astronauts, looking back at the Earth, saw a different world floating in the darkness—beautiful, serene, and peaceful. Later, they saw our home rising above the lifeless landscape of the Moon. The striking contrast reminded them, and all of us, that life on Earth is fragile and we are its stewards.
That first glimpse of “Earthrise” surprised the astronauts, but they managed to take a picture that has since come to be known as “iconic.”
This mission, and those that came after it, gave a huge boost to the environmental movement.
It was the end of a terrible year, but Apollo 8 showed us what humanity could do when we worked together, not as adversaries. On the surface of the planet, we could see little but division and conflict, an obsession with borders and boundaries, and competing ideologies. From the Moon, we saw something different.
It took a long time, half-a-century, but Apollo 8 finally had a complementary mission known as Artemis 2.
The two missions were similar in ways that cannot be ignored, but they were also very different.
When Artemis launched, there was, once again, division on the surface, with wars raging abroad and political tensions at home. Meanwhile, the Artemis astronauts engaged in “Overview Speak,” with Victor Glover talking about love, and how we are “all one thing.” (2)
When the astronauts asked Mission Control for permission to name one of the craters on the Moon after Commander Reid Wiseman’s late wife Carol, it was an unforgettable human moment, summarizing what many said about the four astronauts on Artemis 2: they were “so human,” so “relatable.”
There are two major differences between Apollo 8 and Artemis 2, one of which is a distinction of which I am acutely aware: as noted earlier, no one used the term “Overview Effect” in 1968. I had not yet experienced the insight that produced the term and did not publish my book on the topic until 1987.
The other key distinction is in media coverage and the audience. In 1968, the Apollo mission had episodic coverage. To be sure, the astronauts shared their experiences with the world en route to the Moon and even turned their cameras around to give us our first view of the Earth from a distance. And their Christmas Eve reading from Genesis as the Earth appeared over the lunar surface garnered a huge audience on traditional networks.
However, Artemis 2 took place during the Internet era, with multiple alternate media sources and NASA providing near-continuous video feeds of life on the spacecraft.
Artemis 2 offered a vivid contrast between “Overview Thinking” and “Surface Thinking.” While the astronauts spoke of love and connection, leaders on the surface traded threats and missiles, with one of them promising to obliterate an entire civilization.
“Overview Thinking” focuses on collaboration, cooperation, and an understanding that we are on a spaceship floating through an infinite and eternal universe.
“Surface Thinking” focuses on division, conflict, and polarization. It has been outdated for a long time, and certainly since April 12, 1961, when Yuri Gagarin became the first human to experience the Overview Effect.
We must understand, however, that “Overview Thinking” cannot be a passing thought brought about by one NASA mission. It should become a new paradigm that guides the behavior of the crew on “Spaceship Earth.”
Creating a new paradigm is challenging, and it can even be dangerous. The first heliocentric model of the solar system was proposed by the Greek philosopher Aristarchus in the third century BC. However, it was not until 1543 that Nicolaus Copernicus published his book, which made a definitive case for heliocentrism vs. geocentrism. He was so fearful of how the Church would react to his ideas that he waited until he lay on his deathbed to approve the book’s release.
It may also be dangerous to espouse a new paradigm in our time, but we have no choice: “Surface Thinking” is dangerous, and it is a path that must be abandoned, or at least modified. We have a choice to make as a species, and it will be made in our lifetimes: which mode of thought will guide us in the coming years?
Meanwhile, among the many questions we had about Artemis 2 was whether it might capture any photographs that would match “Earthrise,” one of the best examples of an Overview Effect photograph.
The answer to that question appears to be “yes,” and it is not that Artemis shot another Earthrise photo. Rather, the astronauts captured “Earthset,” a perfect complement to that wonderful Apollo 8 picture.
It’s great news for our species that Artemis 2 scored a resounding success, bringing our planet together in much the same way as Apollo 8 did, so long ago. Very few of the people alive today were old enough to experience Apollo 8!
Everyone deserves, in the words of Astronaut Nicole Stott, an “Earthrise Moment.” (3) Today, we might add an “Earthset Moment.” Some of us have been fortunate enough to experience both!
