NASA scientists are buzzing with excitement over a recent discovery on Mars. The Curiosity rover has stumbled upon a region with an unusual texture near a crater called Antofagasta. From certain angles, the rocks look like they have scaling—almost as if a dragon once sprawled across the surface.
Project scientist Abigail Fraeman describes this discovery as “honeycomb-shaped polygons,” which are found in massive numbers. It’s quite stunning to see them spread out over the landscape in vivid mosaics. “We’ve seen similar patterns before,” she explains, “but never this many at once.”
These intriguing shapes were captured in images taken on April 13, 2026. While it’s still early to draw conclusions, clues are emerging about how these patterns might have formed. On Earth, polygonal patterns often emerge when the ground expands and contracts due to drying or freezing. You might see them in the bottom of a dried mud puddle, known as desiccation crack patterns.
Interestingly, Mars has fewer of these patterns because it lost its surface water long ago. The first desiccation cracks on Mars were only discovered in Gale Crater by Curiosity less than a decade ago. Yet, the feeling at Antofagasta seems different. It’s not just about quantity; the patterns here appear more elaborate, featuring raised ridges that hint at a unique geological history.
Back in 2023, another Martian location, Pontours, was found to have striking hexagonal patterns. Researchers noted that these shapes didn’t form from just one rainy season, but from many cycles of wet and dry spells. Over time, mud would crack into T-shaped intersections that reconnect and develop into hexagons.
This gives compelling evidence of ancient Mars experiencing seasonal changes. Once Mars’s climate shifted, these formations solidified, preserving their shapes for thousands, if not millions, of years. Now, scientists are keen to see if there are similarities between the Antofagasta and Pontours patterns. If so, this could further reveal Mars’s complicated water history.
As Fraeman states, they are collecting detailed images and chemical data to better understand how these honeycomb textures formed. Recent studies suggest that the planet’s geological past is more dynamic than it appears at first glance, indicating a rich history of water activity beneath its dusty surface.
In essence, the findings at Antofagasta may not only shed light on Mars’s past but also spark further investigation into how climates on other planets can change over time. It keeps the door open for more discoveries that could change our understanding of where we live and where we might explore in the future.
