NASA's Curiosity rover has found a field of honeycomb-like polygons in the Martian valley Valle Grande. The polygons measure about 1.3 to 3 inches across, and scientists still don’t know how they formed; potential explanations include ancient wet-dry cycles or sediment processes, and researchers hope the data will reveal clues about Mars’ past climate and geology.
NASA's Curiosity rover, using the CheMin instrument on 20 Gale Crater samples, found hematite crystallites are smaller at higher elevations and larger lower down, with goethite present only higher up. The size pattern, explained by warmer, longer-lasting groundwater and Ostwald ripening, indicates extended warm, wet conditions in ancient Mars and potential habitability deep in Gale Crater.
Scientists analyzed 20 years of images from ESA's Mars Express and ExoMars TGO to track 1039 dust devils on Mars, revealing that wind speeds are faster than previously thought and providing new insights into the planet's weather and climate, which will aid future missions and climate models.
