Former NASA astronaut Ron Garan, who spent 178 days in space and traveled over 71 million miles in 2,842 orbits, has revealed a ‘sobering realization’ he had after seeing Earth from space. Reflecting on his experiences, Garan shared that humanity is ‘living a lie’—a perspective shaped by the overview effect, a phenomenon where astronauts experience a deep, often spiritual connection to the planet. Speaking with Big Think, he described witnessing lightning storms, glowing auroras, and the astonishing thinness of Earth’s atmosphere,
which led him to a profound conclusion: “That paper-thin layer keeps every living thing on our planet alive.” What struck him most was not the global economy but rather an iridescent, life-filled biosphere, making it clear that humanity’s systems prioritize economic gains over the planet’s health. In an interview with Forbes, he described the experience as overwhelming, saying it made him feel deeply connected to everyone on Earth. Since returning, Garan has become a strong advocate for environmental sustainability, founding the Manna Energy Foundation to provide clean water access and launching Fragile Oasis, a project promoting global change. His message is clear: as humanity looks to the stars, we must also prioritize protecting our home planet for future generations.
