#PPOD: When a meteoroid shook the edge of Apollinaris Mons on Mars, it triggered streaks that carved a hundred new scratches on the surface. The European Space Agency’s ExoMars Trace Gas Orbiter captured these dust avalanches on the slopes the night before Christmas in 2023. This image also shows the faint cluster of impact craters in the discoloured region at the base of the slopes. Credit: ESA/TGO/CaSSIS
