NASA’s Curiosity rover found a ‘sea of polygons’ on Mars

NASA's Curiosity Mars rover has discovered a vast field of honeycomb-shaped polygons in a Martian valley called Valle Grande. The polygons, each measuring 1.5 to 3 inches wide, cover a large area, unlike previous small patches found by the rover. Curiosity captured a 360-degree panorama of the unusual terrain, dubbed a "sea of polygons," on June 19th and 20th. The discovery is significant, with project scientist Ashwin Vasavada noting that the scale of the polygons found in Valle Grande is unprecedented.
