Mars lost its atmosphere thanks to giant atmospheric waves—plasma clouds whipped up by solar wind, since the planet lacks Earth’s protective magnetic field. New data from MAVEN and Tianwen-1 confirms these Kelvin-Helmholtz waves are actively stripping away Martian air, turning a once-habitable world into the barren red planet we know today. The process isn’t uniform—it’s concentrated based on solar wind direction—and future missions like ESCAPADE aim to map exactly when and how much atmosphere escapes, offering clues about planetary evolution—and whether other worlds without magnetic fields…
