Overview

• The Perseverance rover detected organic matter and curious discolored spots in a rock named Cheyava Falls.
• Calcium sulfate veins in the rock suggest the historical presence of liquid water, a key ingredient for life.
• The discovery includes 'leopard' spots, possibly linked to microbial activity, never before seen together on Mars.
• Further analysis on Earth is needed to confirm if these signs are biological or result from non-biological processes.
• The findings support calls for a multi-billion-dollar sample retrieval mission to bring Mars rocks to Earth for detailed study.
