Wave-like formations on Mars offer insights into the planet’s icy past, its potential to support life, and how granular materials flow across its surface.

Despite its dry, dusty terrain and thin atmosphere, Mars may have more in common with Earth than previously thought.

In a recent study, researchers from the University of Rochester—led by PhD student JohnPaul Sleiman and assistant professor Rachel Glade of the Department of Earth and Environmental Sciences—discovered that some Martian soil features closely resemble wave-like patterns found in Earth’s coldest regions.

This finding suggests that, despite key differences, both planets may be shaped by similar physical forces and icy environmental processes. Published in Icarus, the study offers new insights into Mars’ climate history, the potential for past life-supporting environments, and the physics of granular material behavior. Figure 1.

Satellite Study Reveals Similar Lobe Patterns on Mars and Earth

Using high-resolution satellite images, the researchers examined nine Martian crater sites and compared them to similar terrains on Earth. They found that Mars' wave-like landforms closely resemble solifluction lobes—slow-moving soil patterns typically found in cold, mountainous areas like the Arctic and the Rocky Mountains.

According to Glade, these formations are “large, slow-moving, granular versions of familiar flow patterns, like paint dripping down a wall.”

The key difference?

The Martian lobes are, on average, about 2.6 times taller than their Earth counterparts.

Gravity and Soil Composition Explain Height Gap in Martian and Earth Lobes

The researchers found that the height difference between Martian and Earth lobes matches predictions based on Mars’ lower gravity and the physical properties of its soil, which allow the lobes to grow taller before collapsing.

On Earth, solifluction lobes form as soil slowly creeps downhill during freeze-thaw cycles. While Mars likely underwent similar freeze-thaw activity, the process was probably driven by sublimation—where ice transitions directly into vapor—rather than melting into liquid water.

The study suggests that Mars may have once experienced icy conditions that shaped its surface much like on Earth, offering new insight into the planet’s climate evolution, the role of water, and where scientists might search for signs of past life.

“Studying how these patterns form helps us better understand Mars’ climate history, particularly the possibility of past freeze-thaw cycles,” says Sleiman [1]. “Though more research is needed to determine when these features formed, this work could ultimately guide the search for environments on other planets that might support—or restrict—potential life.”
