Curiosity Uncovers 3.5-Billion-Year Organic Clues on Mars
TL;DR Summary
Curiosity's analysis of Gale crater clay found 20+ organic molecules, including a nitrogen-bearing compound akin to DNA precursors and a benzothiophene, suggesting ancient organics were preserved on Mars for ~3.5 billion years and that the planet once offered habitable conditions; Earth-based experiments with a meteorite and landing simulations aided interpretation, while ESA plans a 2028 Rosalind Franklin rover to continue the search.
