Perseverance at Jezero: Stratigraphy, Weathering, and a Potential Biosignature in Neretva Vallis (Bright Angel Formation) at LPSC 2025

To the point

Perseverance at Jezero crater is studying ancient Martian rocks to understand the planet’s past and search for biosignatures, focusing on igneous and sedimentary rocks, while in Neretva Vallis the Bright Angel formation shows meter-scale fractured blocks with laminated to structureless textures and little deposition evidence, HiRISE imagery suggests layering that supports the stratigraphy, and poorly sorted conglomerates on the southern margin may hint at a biosignature, with Joel Hurowitz and colleagues credited for a color image of Cheyava Falls using PIXL and SHERLOC during ongoing fieldwork.
