In a mission update late last month, Perseverance team members described the rover's most detailed look yet at a class of features called aeolian megaripples, oversized ripples of sand that can rise to around 6.5 feet (about 2 meters) tall. Unlike smaller ripples that may shift readily, megaripples on Mars are often treated as "mostly inactive," preserving clues about older wind patterns and atmospheric conditions that helped shape the landscape of the Red Planet. In the recent update, the mission team shared an image of a giant wind-formed sand ripple nicknamed "Hazyview."
