The newest discovery from NASA’s Curiosity Mars rover is a field of honeycomb-shaped polygons protecting a Martian valley known as Valle Grande. As Gizmodo reviews, Curiosity has snapped photos of the bizarre terrain texture earlier than, known as polygonal fractures, every about 1.5 to three inches huge, however NASA says it’s beforehand solely discovered them in small patches, “nothing on the size found in Valle Grande.”
Curiosity captured a 360-degree panorama of the “sea of polygons” on June nineteenth and twentieth (Martian sols 4,930 and 4,931) that reveals the feel spreading out in all instructions. Venture scientist Ashwin Vasavada says the Curiosity staff “measured their shapes and chemistry fastidiously and are hopeful there are clues within the knowledge as to how these options fashioned.”
NASA says billions of years in the past, “lakes and streams dappled the decrease foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014.” This terrain may additionally point out there was as soon as water in Valle Grande, primarily based on earlier polygon patches:
Among the polygons that the mission has noticed up to now clearly fashioned as mud cracks, although a wide range of processes can contribute to their honeycomb textures, together with cycles of heat and chilly temperatures or compression that squeezed water out of the sediment when the floor was buried.
