Images taken from Mars are the subject of a new article by NASA scientists studying water on the role of the planet in shaping its landscape and finding evidence of life.
The article, published in the journal Science, is based on images taken in February by NASA’s Perseverance rover from inside the Jezero crater. Scientists believe that a river once flowed into a lake where the crater now exists. Based on images taken by Perseverance, the crater cliffs mark what were once the shores of the delta, and the layers shown inside the cliffs offer a glimpse of how it formed.

The lower three layers indicate a once constant and steady flow of water, suggesting that the planet was “hot and humid enough to support a hydrological cycle” nearly 3.7 billion years ago.
Scientists hope to take samples of sediment from the base layer of the cliffs to examine them for signs of past life on Mars.
