Mars Rover Detects Potentially Groundbreaking Organic Molecules
NASA’s Curiosity rover has detected the largest organic molecules yet found on Mars within a 3.7-billion-year-old rock sample. These long-chain molecules, including decane, undecane, and dodecane, are potential fragments of fatty acids, crucial building blocks of life on Earth. While not definitive proof of past Martian life, this discovery, detailed in the *Proceedings of the National Academy of Sciences*, suggests complex organic chemistry occurred on Mars and strengthens the case for returning Martian samples to Earth for more thorough analysis. The finding also boosts hopes of detecting further biosignatures, despite the planet’s harsh radiation.
