Curiosity uncovers complex organics in ancient Martian sandstone

NASA's Curiosity rover, using a first-of-its-kind off-Earth chemical test with tetramethylammonium hydroxide (TMAH), detected more than 20 organic molecules in 3.5‑billion‑year‑old sandstone from Gale Crater, including naphthalene and benzothiophene, with possible nitrogen-containing heterocycles—evidence of ancient Martian chemistry that could be a building block for life and that will guide future TMAH experiments on Mars rovers and future missions.

Curiosity's bold chemistry test reveals more organic clues on ancient Mars

NASA's Curiosity rover carried out a novel TMAH-based chemistry experiment on Mars that detected more than 20 organic molecules, including benzothiophene, suggesting preserved organics on the planet's surface for over 3 billion years. While not proof of past life, the findings reinforce Mars' ancient habitability and guide future missions like Mars Sample Return and ESA's Rosalind Franklin rover.

Curiosity Finds Diverse Martian Organics, But Life’s Origins Remain Unclear

NASA’s Curiosity rover’s Sample Analysis at Mars (SAM) detected more than 20 organic molecules in Gale crater’s clay‑rich rocks using a first‑of‑its‑kind TMAH thermochemolysis experiment, suggesting macromolecular carbon preserved in ancient Martian sediments; while the findings show organic richness and potential biosignature precursors, they cannot distinguish biological from non‑biological sources, and they align with Perseverance observations to inform future life‑detection missions.
