Curiosity Unearths Giant Honeycomb Textures Across Martian Rocks
NASA’s Curiosity rover captured Mastcam mosaics showing thousands of polygonal, honeycomb-like textures across rocks near Antofagasta crater in Gale Crater, a pattern scientists are evaluating as a clue to Mars’ ancient watery past; researchers are testing hypotheses from drying/wetting cycles and groundwater mineralization, complementing other recent findings of organics in Martian rocks.
