Watch This Dark Volcanic Ash Creep Across the Red Planet
European Space Agency images from the Mars Express reveal a dark volcanic ash blanket creeping across Utopia Planitia, indicating geological activity.

The findings highlight subsurface ice and tectonic features, challenging the notion of Mars as a static, lifeless planet.
