Curiosity detects diverse organics on Mars, hinting at ancient habitability
TL;DR
NASA’s Curiosity rover, via a wet-chemistry experiment on a Mary Anning rock at Gale Crater, uncovered 21 carbon-containing molecules, including seven not previously detected on Mars. The organics could be preserved for about 3.5 billion years, reinforcing the idea that ancient Mars was habitable, though the findings do not prove life. Researchers say definitive answers require returning samples to Earth, and future missions with similar chemistry experiments (e.g., ExoMars Rosalind Franklin, Dragonfly) will continue probing Mars’ organic past.
