Mars Wind Currents Reveal a Surprising Feature

NASA's MAVEN mission has been studying Mars' upper atmosphere since 2015, mapping high-altitude global wind patterns for the first time. By analyzing wind speed and direction, MAVEN has created a global map of wind currents 200 kilometers above Mars. The data revealed unexpected features, such as the influence of surface terrain on wind patterns. These findings provide insights into Mars' ancient climate, helping scientists understand its transition from a warm, wet environment to the cold, dry planet we see today.
