Mars subsurface holds complex organics

Curiosity detected more than 20 organic molecules in the Martian subsurface, including a nitrogen‑bearing compound similar to DNA precursors and meteorite‑delivered sulfur‑rich organics such as benzothiophene. The finding shows that ancient organic material can survive on Mars and that meteorite delivery plus subsurface preservation may supply prebiotic ingredients without invoking biology. — This changes public and policy conversations about life detection, sample‑return priorities, and planetary protection by making Mars a more credible source of preserved prebiotic chemistry.
