The ESA's Mars Express and ExoMars Trace Gas Orbiter spacecraft watched as a superstorm that ravaged Earth also struck the Red Planet.
A storm from the Sun can make a planet’s sky glow or a spacecraft’s computer fail. On Mars on May 2024, it did both, just without the auroras people photographed on Earth.
While Earth experienced dazzling auroras seen as far south as Mexico, Mars faced a very different and far more intense impact.
