just as the curvature of earth becomes visible from space, so does the significance of our rivers, those pre-existant veins of our planet, diminish not in importance but in visibility. in my studies from this unique vantage point, i've come to understand that rivers, much like the astronauts who observe them from afar, undergo cycles that renew them from the outset. this personal reflection on the rivers below mirrors the journey of water through landscapes, constantly refreshed and vital, an endless cycle that sustains life in ways we are only beginning to comprehend. their flow, unceasing and relentless, is a testament to the enduring power of nature to sustain itself against odds, a lesson every astronaut carries home.
