The presence of glacial features in the mid-latitudes of Mars suggests that the currently dry, red planet experienced alternating cold and warm periods, driven by repeated freeze–thaw cycles throughout its evolution. These climatic fluctuations are caused by changes in Mars’ orbital parameters – especially the tilt of its rotation axis, known as obliquity. Unlike Earth’s relatively stable tilt of about 23.5°, thanks to our loyal companion the Moon, Mars’ axial tilt varies more dramatically and frequently due to gravitational influences from other planets. These obliquity cycles cause periodic shifts in Mars’ climate – and with them, changes in the distribution of ice. Simply put: during periods of high obliquity, ice spreads from the poles toward the mid-latitudes. When the tilt is lower, as it is today, the ice retreats back to the poles, leaving behind visible traces in the landscape. The consistent presence of such features along the dichotomy at similar latitudes may point to global climatic drivers rather than localized environmental changes.
