Mars: The Planet That Lost Its Atmosphere | Science For Sleep

Mars was not always the cold, silent desert we see today. Across its red surface, ancient river valleys, dried lakebeds, layered rocks, and hidden deposits of ice reveal signs of a world that may once have been warmer and wetter. So what happened to the Martian atmosphere—and where did all that water go? In this calming science-for-sleep journey, we explore how Mars slowly changed over billions of years. Discover how its smaller size, weaker gravity, cooling interior, fading magnetic field, solar wind, and atmospheric escape may have transformed the Red Planet. We will also follow clues found by Mars rovers, orbiters, and NASA’s MAVEN mission to uncover what remains trapped in rocks, minerals, polar ice, and beneath the dusty surface. Relax, close your eyes, and drift through the quiet story of how Mars lost its sky.
