Curiosity Rover Uncovers Mars’ Watery Past with Polygonal Formations
This June, NASA’s Curiosity rover climbed Mount Sharp, reaching a high vantage point. From this point, it reveals honeycomb-like patterns stretching across the Martian landscape, a mesmerizing sight stretching to the horizon.

These formations are polygonal fractures, each measuring four to eight centimeters in width. Though the rover had previously encountered smaller patches, never before had it discovered such an expansive field. This intricate pattern resembles what you might see when mud dries and cracks on Earth, whether in your driveway or in the arid expanse of Death Valley.
Mystery of the polygons unfolds as Curiosity Rover Uncovers More
The team behind Curiosity is currently investigating the origins of these Martian polygons. While similar formations on Earth can result from cycles of freezing and thawing or sedimentary pressure squeezing water out from underneath, the vehicle explores new possibilities in the source here that remains a matter of scientific inquiry.
All of the candidates involve water. The rover has uncovered more as it has been exploring Mars for fourteen years, twelve of which have been spent ascending a mountain where ancient lakes and streams once flowed. Its findings include organic molecules that could be precursors to RNA and DNA, essential components of life.
Tracing life’s roots in Martian soil
Despite these discoveries, the origins—whether biological or strictly geological—remain unknown. The Martian surface, showing hand-sized dried cracks, offers a haunting glimpse into a planet that transitioned from a wet to an arid landscape billions of years ago as it reveals more of its secrets.
