NASA reports that its Curiosity rover is observing a newly photographed field of honeycomb-like surface textures as it climbs a Martian valley called “Valle Grande.” The rover images show polygonal fractures—cracks that form repeating geometric cells—covering an area described as larger than any similar field previously seen by the mission. Each polygon is estimated to be about 1.5 to 3 inches (4 to 8 centimeters) across, based on the scale of the observed features in the rover’s images. NASA and Phys.org both note that Curiosity has identified small patches of polygonal fractures on earlier occasions. However, both sources state that the current discovery stands out for its scale, with more extensive coverage in Valle Grande than seen before. The reports frame the finding as part of ongoing geological observations during Curiosity’s ascent through the valley, using high-resolution imagery to document the distribution and size of fracture patterns on the Martian surface.
