Study Finds An Ancient History Of Water On Mars That Shifted Over Time
[Purdue University] From orbit, a carbonate-rich band of rock along the inside edge of Mars’ Jezero Crater looked like it might be the remains of an ancient lakeshore. Then NASA’s […]

Complex Water Systems Revealed On Early Mars
[NASA] A new study reveals that Jezero Crater’s enigmatic ‘Margin Unit’ was shaped by a complex sequence of ancient lakes, groundwater systems, and hydrothermal fluids.
![(A) Summary interpolation of the extent of bedrock geologic units based on in situ mapping. The width of the mapping corridor is ∼120 m. White dots are positions occupied during the traverse for which images are available for mapping. (B) Summary of interpreted stratigraphic relationships between identified lithologic units along the Jezero crater floor traverse (A and B adapted from Crumpler et al., 2023; Fig. 19). (C) Orbital image of Jezero crater floor with the path of the Perseverance overlaid in white. (D) Inset of the crater floor campaign, with all Máaz abrasion patches shown (Guillaumes, Montpezat, Bellegarde, and Alfalfa), and the OEB (Octavia E. Butler) landing site indicated. The Guillaumes and Alfalfa abrasions are highlighted, as they are the focus of this article (altered from NASA). -- [Astrobiology (journal)]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/The-Possible-Aqueous.png?resize=1200%2C718&ssl=1)
