New images from Mars will guide search for evidence of ancient life, says study

Pictures taken by Perseverance rover show how water helped shape planet's landscape billions of years ago

Images from Mars reveal how water helped shape the red planet's landscape billions of years ago, and provide clues that will guide the search for evidence of ancient life, according to a new study.

In February, Nasa's Perseverance rover landed in Jezero crater, where scientists suspected a long-gone river once fed a lake, depositing sediment in a fan-shaped delta visible from space.
