New images from ESA's Mars Express reveal evidence of past ice ages on Mars! We explore the Coloe Fossae canyons and the Ismenius Lacus quadrangle, uncovering swirling patterns called lineated valley fill (LVF) and concentric crater fill (CCF).
These features, similar to glacial till on Earth, suggest glaciers once flowed across the Martian mid-latitudes. Learn how studying these ice flows helps us understand Mars' transition from a warmer, wetter planet to the cold, dry world we see today.
Discover how variations in Mars' axial tilt (obliquity) drove these climate shifts, and what this tells us about the geological and environmental history of the Red Planet.
