NASA Curiosity Finds Rare Organic Molecules on Mars That Expand Life Possibilities

Some compounds are unlike anything Curiosity has seen

NASA says its Curiosity rover has detected the most diverse set of organic molecules ever found on Mars, including multiple compounds not previously seen on the planet. The findings come from an ancient rock sample drilled by Curiosity and bolster the case that Mars once had conditions favorable for life, even as researchers stress that this is not direct proof of biology.
