Study finds Martian dunes were eroded by a shift in prevailing winds after the planet’s last ice age

Detailed analysis of data obtained by the Zhurong rover of dunes located on the southern Utopia Planitia of Mars suggests the planet underwent a major shift in climate that accompanied changes in prevailing winds. This shift likely occurred about 400,000 years ago, which coincides with the end of the last glacial period on Mars.
