Mars Reconnaissance Orbiter records movement of ice on Mars

On August 18, 2023, the Mars Reconnaissance Orbiter (MRO) recorded ribbed lines carved into the Martian surface by the gradual movement of the ice. Although the accumulation of surface ice is mostly limited to the polar caps of Mars, these patterns are observed in many non-polar regions of Mars.

As the ice flows downward, rocks and soil are uprooted from the surrounding terrain and move across and within the ice surface. Although this process takes perhaps thousands of years or more, it creates a network of linear patterns that reveal the history of ice flow.

MRO has been studying Mars since 2006. Its instruments zoom in on long-distance images of the Martian surface, analyze minerals, look for subsurface water, track how much dust and water is dispersed in the atmosphere, and monitor global weather on a daily basis.

These studies identify mineral deposits that may have formed in water over long periods of time, look for evidence of shorelines of ancient seas and lakes, and analyze sediments layered by flowing water over time. Source
