Crustal Water Reservoir On Early Mars

[Geophysical Research Letters]. The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non-destructive analytical techniques for early three-dimensional characterization.

(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)]

The Possible Aqueous Origins of Manganese Alteration Minerals in the Máaz Formation of Jezero Crater

by Keith CowingJuly 28, 2026July 28, 2026

[Astrobiology (journal)] Home to a lake around 4 billion years ago, Jezero Crater is a unique location to study the interplay between igneous processes and aqueous alteration on ancient Mars.

This view looking back up at the outside lip of the 490-foot-tall (150-meter-tall) rim of Jezero Crater was taken by the Mastcam-Z instrument aboard NASA’s Perseverance on May 15, 2025, the 1,505th day, or sol, of the rover’s mission to Mars. Larger imagery -- NASA

Mars Perseverance Rover’s Panoramic View of Broom Point

by Keith CowingJuly 16, 2026July 16, 2026

[NASA] The bright-colored rocks exposed across the slope, running from middle left to middle right of the image, belong to a formation the science team calls the “Broom Point member,” […]

NASA’s Perseverance took this selfie at “Witch Hazel Hill” on Jezero Crater’s rim on May 10, 2025. The small dark hole in the rock in front of the rover is the borehole made when the rover collected the “Bell Island” sample. The small puff of dust left of center and below the horizon line is a dust devil. Credit: NASA/JPL-Caltech/MSSS larger image
