NASA’s Curiosity rover has actually found the biggest spot of polygon-shaped ground fractures it has actually ever seen on Mars, a discovery that might expose more about the world’s watery past.

The uncommon surface depends on a valley referred to as Valle Grande on the lower slopes of Mount Sharp inside Gale crater, where Curiosity has actually been climbing up for many years.
A 360-degree panorama caught June on 19 and 20, 2026 programs honeycomb-like polygons extending to the horizon in every instructions.
Each fracture determines approximately 4 to 8 cm (1.5-3 inches) throughout, and the pattern even climbs up the flanks of a neighboring sand-capped butte the group has actually nicknamed Miraflores, which increases about 6 m (20 feet) above the surrounding surface.
Interest has actually photographed little clusters of these geometric shapes before, however absolutely nothing on this scale.
“We’ve seen a great deal of interesting landscapes through Curiosity’s eyes, however this sea of polygons took our breath away,” stated Curiosity staff member Dr. Ashwin Vasavada, a scientist at NASA’s Jet Propulsion Laboratory.
“We determined their shapes and chemistry thoroughly and are confident there are ideas in the information regarding how these functions formed.”
According to the group, not all Martian polygons share the exact same origin story.
Some patterns Curiosity has actually formerly analyzed were left by drying mud, while others can form through duplicated freeze-thaw cycles or from compression that requires water out of buried sediment.
The scientists have actually not yet figured out which system– or mix of systems– produced the recently spotted field.
“Billions of years earlier, lakes and streams dappled the lower foothills of Mount Sharp, a 5-km- (3-mile-) high mountain that Curiosity has actually been rising because 2014,” they stated.
“The rover has formerly exposed chemistry left over from Mars’ watery history, consisting of carbon-based particles thought to be precursors to RNA and DNA, 2 nucleic acids that bring hereditary info.”
“We have no other way of understanding whether these natural particles were produced by biologic or geologic procedures– either course is possible– however their discovery reconfirmed that ancient Mars had the ideal chemistry to support life.”
