Windblown yardangs on Mars | Space photo of the day for Oct. 15, 2026

A striking image captured by the Mars Express spacecraft reveals prominent windblown yardangs across the Martian landscape on October 15, 2026. The photograph showcases distinct rippled ridges formed by powerful winds acting upon loose sand deposits. These features, known as yardangs, are characteristic landforms shaped by aeolian processes – specifically, the movement and deposition of sediment by wind. Scientists believe these patterns provide valuable insights into the planet’s atmospheric conditions and past climate history. This visual evidence further supports ongoing research regarding the dynamic nature of the Red Planet's surface.
