Chinese rover finds Martian climate changed drastically 400,000 years ago

The Chinese Mars rover Zhurong has found evidence of a dramatic change in Martian climate 400,000 years ago in the form of dark ridges overlying light dunes that stretch across the sands of Utopia Planitia the rover is exploring.

Scientists led by Li Chunlai of the National Astronomical Observatories of the Chinese Academy of Sciences used the rover’s instruments in conjunction with high-resolution observations from China Tianwen-1 Mars orbiter to take a closer look at the large sand dunes near Zhurong landed in May 2021.
