Perseverance’s 'Sapphire Canyon' Sample Shows Potential Biosignatures — Earth Return Needed to Confirm
NASA’s Perseverance rover recovered a 'Sapphire Canyon' rock from Jezero Crater containing organics and iron‑phosphate and iron‑sulfide textures, plus tiny 'leopard‑spot' and 'poppy‑seed' features that could be biosignatures. Confirmation requires returning the sample to Earth for laboratory analysis, and return plans remain uncertain.
