Curiosity Rover Finds Largest Organic Molecules Yet on Mars, Hints at Prebiotic Chemistry

NASA's Curiosity rover has discovered the largest organic molecules yet found on Mars: decane, undecane, and dodecane. These molecules, likely fragments of fatty acids—building blocks of life on Earth—were found in the 'Cumberland' rock sample from Gale Crater's Yellowknife Bay, a region that shows evidence of an ancient lakebed. The discovery suggests prebiotic chemistry may have been more advanced on Mars than previously thought, increasing the possibility of past life. The sample's rich clay minerals, sulfur, nitrates, and methane further support the ancient lake environment. This finding strengthens the case for returning Martian samples to Earth for more detailed analysis.
