Within Jezero crater, the Perseverance rover currently explores the lowermost-exposed scarp of the delta (Fig. 1) [1,2]. Here we: (1) present the distribution of light-toned veins currently observed via the rover along its route in Jezero crater; (2) introduce compositional results of veins as analyzed via Perseverance’s SuperCam instrument, and place them into the context of results from the other instruments.
