New Research Points to Possible Seasonal Climate Patterns on Early Mars

Research suggests seasonal climate patterns on early mars

Scientists aren’t entirely sure how life began on Earth, but one prevailing theory posits that persistent cycles of wet and dry conditions on land helped assemble the complex chemical building blocks necessary for microbial life. This is why a patchwork of well-preserved ancient mud cracks found by NASA’s Curiosity Mars rover is so exciting to the mission’s team.

A new paper in Nature details how the distinctive hexagonal pattern of these mud cracks offers the first evidence of wet-d...
