NASA’s Curiosity rover found a ‘sea of polygons’ on Mars
NASA's Curiosity rover has discovered a vast field of honeycomb-shaped polygons in a Martian valley called Valle Grande. Scientists believe these formations may provide evidence of ancient water cycles on the planet.
Why it matters
This discovery offers new insights into Mars' geological history and its potential for having supported water in the distant past.
The latest discovery from NASA’s Curiosity Mars rover is a field of honeycomb-shaped polygons covering a Martian valley called Valle Grande. As Gizmodo reports, Curiosity has snapped pictures of the unusual terrain texture before, called polygonal fractures, each about 1.5 to 3 inches wide, but NASA says it’s previously only found them in small patches, “nothing on the scale discovered in Valle Grande.”
