Mars died 3.5 billion years ago — and we now know why. A magnetic field collapse exposed the planet to the Sun’s solar wind, stripping away the atmosphere and boiling off the ancient oceans. ESA missions like Mars Express and ExoMars still map the traces of this catastrophic past. A world that once looked Earth-like… became silent forever.
