Diverse organic molecules on Mars revealed by the first SAM TMAH experiment

NASA's Curiosity rover has discovered over 20 organic compounds in Mars rock samples using a novel SAM TMAH experiment, including a nitrogen-bearing molecule structurally similar to DNA components—a first for Mars. The findings demonstrate that Mars can preserve complex organic material for billions of years, supporting the hypothesis that ancient Mars may have harbored conditions suitable for life. While the compounds themselves don't prove past life existed, they provide crucial evidence for assessing Mars's ancient habitability.
