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.
