Astronaut’s ‘Sobering Realization’ After Seeing Earth from Space
Former NASA astronaut Ron Garan spent 178 days in space, orbiting Earth 2,842 times and

covering over 71 million miles. But what truly changed him wasn’t the distance traveled—it was a realization that humanity is “living a lie.”

The Overview Effect
Garan experienced the ‘overview effect,’ a cognitive shift astronauts often feel when viewing

Earth from space. “I saw the paparazzi-like flashes of lightning storms, I saw dancing

curtains of auroras that seemed so close it was as if we could reach out and touch them,”

he told Big Think. But what struck him most was “the unbelievable thinness of our planet’s atmosphere.”

A Harsh Truth
In that moment, Garan understood the fragility of Earth’s life-support systems. “That paper-thin

layer keeps every living thing on our planet alive,” he noted. From space, he didn’t see economies

or borders—just “an iridescent biosphere teeming with life.” He added, “Our human-made systems

treat everything… as the wholly owned subsidiary of the global economy. It’s obvious from the vantage point of space that we’re living a lie.”

A Call for Change
Garan’s experience “just blew him away” and deepened his connection with humanity. Since returning,

he’s championed environmental sustainability, founding the Manna Energy Foundation and Fragile

Oasis to drive global change. His journey underscores a crucial lesson: we must prioritize Earth’s well-being over short-term economic gains.
